Post subject:  Winter overhaul

Well, since I wasn't able to get to the track this year, it looks like my work will be cut out for me over the winter. I've talked it over with the wife, and there's gonna be alot of work done to the car to get it ready for next year. Here's a few things on the list already:

- Rewire the car. It works now, but I don't like how it's done. There is a better way than it is right now.
- Chassis updates. After a quick trip to Mark Williams and a look at the SFI book, I can do the upgrades here at home in just a few days for less than 1/4 of what it was going to cost to have a chassis shop do it for me. Will also add a couple of small things, change a couple of things, and "adjust" some others......
- Shifter. Going to replace it with a better one, and see if the new one will fit next to my leg on the side of the cockpit instead of between my legs, where it is now. Also will do both shifts automatically instead of just one.
- Replace fried delay box. Figured might as well upgrade now, just haven't decided on which one yet.
- Possible repaint. The car looks nice now, but me and the wife want to repaint it another color. I do need to do some bodywork on the side panels, but the new color isn't set in stone yet. Also considering having the frame re-powdercoated after the upgrades.
- New motor. My buddy that gave me the car might be helping out with that part, so if it comes together, I'll have a pretty radical 598" motor over the somewhat mild 461" that's in there now.
- Fuel system. Already decided on this one. Right now it has two fuel pumps, one for the motor and one for the juice, and neither are enough for what they are doing. Only thing I haven't decided yet is what pump. If I stay with gasoline, I'm looking at both belt driven and electric. However, alcohol injection is in the future, so we'll see where that goes. I just know that either way, I need a bigger pump.
- New brake calipers. The ones on the car now are the originals. Made by Airheart. I can get kits to overhaul them, and new pads, but the cost of just the overhaul kits is more than a new set with pads!!!
- Reseal the rearend. Also gives me a chance to take a look at the gears, and might do a ratio change, depending on funds.
- New front rims. If the budget allows, of course, as they are proud of dragster wheels. The ones on there now are a bit on the heavy side though, and dinged up some. This is a "like to have", not a "need to have".
- Taller windscreen. The one on there now doesn't even extend above the dash, and I'd feel better with it taller anyway. Not a big deal here, just a sheet of lexan and a steady hand.

That's about all I can think of for now. I'll post pics of my progress as things move along. I'll be looking at deals on stuff as the work gets done, so if you have anything that I might be able to use, let me know. Not sure when I could get it off of ya, but at least I'll know its there if I do need it!

Thanks guys!
Mark

Hi Mark,

Here is my input on some items that may work good for your application, and I will highlight them in color.

B&M makes a nice trim line shifter for dragsters, and there are a few other companies also that make them, but there PRO BANDIT MODEL is a nice piece and your choice of handles, either a blade design, or a Magnum grip which is a little wider, and you can even get it with a shiftnoid deal. It has a reverse lockout and is NHRA/IHRA cirtified for useage.
Did you say you shift twice???? :-k seems to me that most diggers run Powerglides due to there lower amount of engine power needed to run them, one less gear to worry about going bad, wayyyy less weight, and overall a very nice range of gears now a days. This would also give you ONLY 1 shift also, the 1-2 and that's it. JMO on this item.

I just know that either way, I need a bigger pump.

Fuel pump-I would say anything higher than a 400 gph pump would be sufficient to run your newer engine combo and Magnafuel is one darn good system but there are others out there for your choice. Run the biggest line you can from the fuel cell to the filter, to the pump and then back to the engine, then downsize as needed to the other components and use your regulators to finish off the press. needed.

If your going to run alcohol, you may want to look into a belt drive alky pump, that way as your engine needs increase for alky, your pump will be there to supply it, rpm increase = volume increase and many alky racers have this setup. Or, you can go old style and get the Enderle camshaft direct drive setup but that requires the need to buy a timing cover but eliminates any belt problems as it is gear driven. Ign. system may need an upgrade if your going to run alky also for maximum spark capacity. JMO though on that part, a MSD 7AL-2 OR -3 will work fine. The 7AL-3 has all the retard functions, and rpm chip spots available for your juice also so look into that box for sure.

That's it for me =; =; good luck on all the upgrades.

Post subject:  Re: Winter overhaul

Thanks for the input John. Here's what I have so far: The car is equipped with a TH400, and I'm going to keep it in the car. Just don't have the extra capital right now for a powerglide setup. Just doing what I'm going to be doing is gonna strain the budget as is. Hopefully my buddy will help out some, as he's said he would. The shifter I'm looking at is from Precision Performance Products. Talked with them on the phone, very nice, helpful people. One of the few places that I called that didn't try to upsell anything, in fact, they recommened the lower priced shifter and said they could add the features that I wanted for less money than buying one already fully equipped. I like that. What's nice, is it's only 3/4" wide, so I'll have more space to mount it than I do right now.

I already have an MSD 7al-3 in the car now. The only thing I'd like to change about that is the coil. It has the older Pro-Power coil now, I'd like to upgrade to the HVC II.

I've looked at the Magnaflo, and it's got a solid rep. I'm also looking at Aeromotive, both electric, and their belt driven. I'm kinda leaning towards the belt driven pump, as I'd like to get some of the electrical needs reduced, but I'm not committed yet. Still need to really look at what I want to do and what will do the job for me. Not leaving any options out though, and I'm open to all input.

The biggest obstacle is the nitrous system. Right now it's just a cheater system from nos. I'm looking at some of the new stuff out there now and there is alot better stuff on the market. I want to stay with a plate system, so if I go injection later, I won't have to drill the intake for another set of nozzles. Again, this is one of those things that I need to sit down and really plan out. I might just end up building a system from scratch.

That's it for now.

Thanks!
Mark

I'd seriously consider running a glide and selling the TH400, they're a simple box, you can build them yourself, takes all the power you can throw at it with part off the shelf. A shorty box or set up shouldn't be too much money.

On the wiring, this is something I need to do on my car, it works but just not to my taste

For calipers I use Wilwood all round. It works out cheaper to by their whole set up for a 9in with discs, top hats and caliper brackets than it does to buy the calipers individually. Aerospace make some nice looking calipers too, not used them but was impressed how nice they look.

On the Nitrous, tap the manifold now and just plug the holes with a bung, With alky I'd run a cam driven pump, and keep the crank pulley free for an alternator and vacuum pump.

Post subject:  Re: Winter overhaul

I'd love to put a glide in it, but there would have to be considerable work done to the chassis as well to put one in, and that's what I'm trying to avoid. Not saying it won't happen in the future, but the car will go down the track with what it has now and as I said before, that's money I can use elsewhere.

I do plan on getting Wilwood calipers, had them on my last car and loved them. Not changing the whole setup though, as the rear is set up as a floater, and everything but the calipers is in great shape. This used to be a top alcohol car, so that part is beefed up for that. I'd overhaul what I have, but like I mentioned in my last post, Airheart is proud of their stuff.........overhaul kits and new pads are almost twice the price of new Wilwood calipers and pads...........No brainer here.

As for the manifold I have now, I'm not doing anything to it. It won't be used on the new motor, whichever way it ends up getting built. As for the motor that's in it now, it's staying as is until replaced. Pump gas, hydraulic cam, little maintenance. Strong running motor that does the job for now. That will most likely end up going back to my buddy who gave me the car.

The fuel system will take some planning. I just don't want to get a new pump and hook it up. I need to know my new fuel system will do whatever I need it to do, and I need more info on my build before I can do that. One thing for sure though, I'm switching the pumps I have around until they get replaced. The Holley blue is going to feed the nitrous, and the Mallory Comp 140 will feed the engine. Right now it's the other way around, and I know the Holley pump is too small for the motor right now.

I'll have some pics up this week, feel free to comment, add to, question, or otherwise.

Thanks!

Mark

Well, still working on the pics, but have started work on the car. Basically started stripping it down to get ready for chassis updates, which I hope to do first, but not sure if that will happen that soon or not. I am going to work on the wiring and some other stuff right now though, as I can build most of the new harness as it is, and install it later. Gonna have some used parts off this too, I'll post those on the buy and sell as soon as they are off the car.

Post subject:  Re: Winter overhaul

Thought I'd update where I'm at with the car. Just finished my materials list, and most of the parts list for all the upgrades. That was a chore in itself. You never really know how much work you need to do to a car until you really get into it!!! I've gotten the wire harness torn out, and quite frankly, I don't know how it even ran!!! Most of the grounds were to aluminum panels bolted to powder coated CM tabs!!! I'm wondering if that also had something to do with my delay box cooking itself......The wide open switch for the nitrous on the carb I thought was connected to a relay.....Nope........the solenoids themselves were connected directly to the switch, after coming from a circuit breaker under the dash, then back out to the solenoids!! The transbrake wire was activating the relay to provide power to the circuit! I'm surprised that the switch didn't fry as well! Basically what I've found was alot of unneeded wiring and poor grounds. Also, all of the high current stuff on the car was routed through the switches instead of a relay. I started trying to save some of the wiring, then after seeing how it was all done, decided to just get rid of it all and start over from scratch! Won't take long to build the new harness, just gotta figure out where to put the relay panel and such......

I'd have some pics up, but the wifey has been dragging her feet with them!!! Got them on her camera, but she still hasn't downloaded them to the puter! So, hopefully this weekend I can bug her enough to get that done. I'll post them as soon as I can.

More to come......

Just thought I'd update everybody on where I'm at with the car. Right now, it's stripped completely down, and I've started building the new wire harness for it. New dash is welded together, I just got the new tubing for the updates, and my heads off the big motor are in the machine shop. I'll be cutting the old cage off and getting the new tubing bent in the next week or so and working on the updates at the footbox area as well. Once the chassis work is done, I can start putting it back together! I'll clean off the car and take some pics, right now it's got stuff piled on it everywhere! Can't wait to get it done!

I finally got my website updated with some new pics of the work on the dragster! Let me know what you guys think!!

Post subject:  Re: Winter overhaul

Just thought I'd let you guys know where I'm at with the dragster. I've got all but a couple of pieces of tubing, and the footbox area only needs one more piece fitted then it can all be welded up. The shoulder hoop and cage comes next after that, then putting back on the body panel mounting tabs, rewiring the car, installing the new fuel system, and finally dropping the new motor in. I've got most of the parts for the new motor, only missing a few more things. Racing budget took a big hit though, as the wife lost her job last week. Hopefully she'll find another one soon, as I can't make the house payment by myself. We're hopeful though, so say a few prayers for us! As far as the car goes, I've got alot to do that doesn't cost anything but my time, and will continue to work on that. I just wish I had my own tig!!! My wife's cousin is supposed to do the welding for me, but he's so busy now I really doubt that will happen. He wants me to take the chassis over to his shop so he can weld it there, then bring it back to my house for more fitting, then back to the shop.......Well, you get the idea, just not feasable....and not sure when he'd be able to get to it. So, I might sell my mig's and see about getting a tig instead. Either way, we'll get the car done this year one way or another. Might only get to make one pass, but I'll get it there! I'll update my website again pretty soon, and hopefully have some more things to put on there. Anyway, good luck to everybody this year!

Post subject:  Re: Winter overhaul

Can you believe it? After two years and about $25 bucks (hahahahahhahaa) it's finally alive! Started it for the first time Friday afternoon! It's still gonna need a bunch of tuning to get it right, but it starts and runs! Oil pressure is good, cooling system is working good, starter works good, and it sounds mean as hell!!!! I haven't updated anything in so long it's not much to look at right now, but I promise I'll get it done! The wife did post a couple of short vids on you tube, just need to go to my facebook page to link to them. I'm hoping to make the track Wednesday for the first bit of testing! Wish me luck!

Post subject:  Re: Winter overhaul

Well, that's another step in the right direction! The dragster I bought back in March is requiring more work every time I get near it as I keep finding stuff that I don't like. Next thing ya know, that part is off the car and I've got to make another or replace this or that. Latest item is the dash but got a piece of aluminum Thursday to make a new one out of. Now I have to decide how I want to do it?

But glad to hear you're finally ready to smell some smoke! Hope it works out well for ya and that it comes home in one piece!

Post subject:  Re: Winter overhaul

Wednesday test for sure! Carb is coming around, but I don't think the neighbors appreciate it very much. This car is LOUD! My plans are for a couple of easy trips down the track footbraking it and very soft launch. I'll step it up every run with the intent of having a full out pass to the 1/8th mile as my last run. We'll see! I'll post my results if my plan works out!

Post subject:  Re: Winter overhaul

Well, we made it to the track this last Wednesday for test and tune! Tech was a breeze, and all I needed to do was a bit of setup before we made our first run. My plan was just to drive the car down the track first run and get a feel for it. Nothing fancy or fast, just make sure everything was going to be ok. First run ended up being in the 15 second range, but that's all I was looking for. Only had a small water leak and nothing else. Second run I left off the brake, but fairly soft. 1.55 60' time and ran a 13.xx at about 86 mph. Car felt good, but steering was just a bit out of whack. A quick check and adjustment in the pits fixed that. Last run for the night (lots of street cars on Wednesdays so not many chances for runs unless you hot lap your car and I'm not going to unless I'm racing!) I planned to get into it a bit. Left off the brake and with quite a bit of rpm. Car left straight and true, shifted fine, and I backed off then ran about half throttle all the way down the rest of the track. Didn't realize I never got enough rpm's back into it to make the second shift! Pedaling it and cruising through the lights at about 1/2 throttle I realized I was still in second gear and never made the shift to third! Oh well, I ended up running a 12.15 at about 89 mph without even trying. This thing is going to be fast!!!! Here's what I learned during this test session and need to work on:

1. Carb is stupid rich at idle and part throttle. Need to lean it out and clean it up quite a bit. I've done some tuning on it and have had some help from Jmark and Adam from Ninja fuel systems. It's getting better, just need to keep plugging away on it. O2 sensors are in the future, but don't have the budget for them right now.

2. Need a new water neck. The one I had leaks where the cap seals to it. No biggie, I didn't get a new one to save a few bucks to get it up and running. It will get replaced now so it doesn't leak anymore.

3. I need to get a spring to put in the lower radiator hose until I can get custom piping done. Hose is collapsing during cooldown and I need to stop that.

4. Something happened to my tach and it doesn't work anymore. The only time I knew what my rpm's were is when the car shifted gears. I can't go without a tach, so a new one will be coming with the new water neck. I have no clue as to what the engine was turning when I made my runs, but it sounded like it wasn't hardly turning at all.

5. My firesuit is hot. I have no choice but to loose weight when I'm at the track. Imagine being in a sauna wearing a snowmobile suit..................

6. I had alot of fun! It was great to get out on a track again, and I started racing at this track so that made it even better! I can't wait to go out again and run it alot harder, then go for my license!

More updates to come!
