It's going on a relatively mild 482 BBC. It's a small roller cam with Dart 310 heads and victor jr. intake. I broke the trans the first weekend out with the motor last year but it seems to run around the same ET's as Mark is now at 8.40's around 158-159mph

The 1050 should be fine with regular boosters.

Good news from mine today, didn't win but won the first two rounds against some tough opponents at the Bradenton divisional in S/C. First round was Dave Scilluto, many time local track champ. .002 and an 8.79, he decided he wanted the stripe so he went 8.77. I had the fastest B/O ET to win... =; So I dialed my t-stop a little more, starting to get it a little closer. Second round was none other than Troy Coughlin Jr. O:) So I gave him a .008 to his .011 an an 8.932 to his 8.930, MOV was .0015 \:D/ Next round missed the tree a little, .029 to his .028. Ran an 8.894 to his 8.898, took the stripe by .0038. Would have had to give him the stripe to win. I have two of the 3 more runs to look at later on the Racepak. Next race in a couple weeks if the weather is good, I'll try some different metering blocks then.

Congrats on the round wins! It's always nice to put the big dogs in the trailer and sometimes that's almost as good as a win IMHO!! ;-)

OK, some updates. Tried the alcohol blocks, but it seemed like there was some leakage from somewhere into the idle circuit making idle and transition a bit fat. It ran clean down track but with .170 jets it ran the same MPH as it did the next run with the other blocks and .164 jets. I'll try and figure the other blocks out, but it will be after the Gatornationals. I need to recalibrate the O2's and possibly swap sides, one side show a little leaner than the other. Still they sit around the low .90's Lambda and the plugs are getting a little color to them, so it may be rich enough but just not showing on the O2's. I did manage to pull out a win, one by run, one run was tight taking a .004 stripe, and the last three easy wins.

Congrats on the win!! Send me a short writeup and you'll be the first winner of this new year. \:D/

Interesting on the blocks?? Was the tuneup the same other than the MJs? :-k

Alcohol metering blocks with about .195 mainwells, .170 jets, same IFR size. I reused the gasket, realized after the fact that it may not have been sealing well between the emulsion well and the idle feed passage below it. I will try again, but need to leave it alone for the Gators.

Mark - Great job in the win!

Interesting results with the alcohol blocks, I guess its somewhat good news in the fact that there wasn't anything wrong with the first set of blp blocks. I've been wondering if there is there any chance that the large amount of booster insert exposure you have with the combination of slots and holes is too much and it's not allowing you to create enough signal to pull fuel from the mainwell?

I just swapped everything over to my 1050 mainbody so we'll see what results I see when the snow melts in a few weeks. Any guess of a starting jet for your basis 1150 tune (but with more standard 12 hole boosters opened up to .063 per hole) applied to a 1050 mainbody? I need to get a few more blp primary jets so right now I have a mix of holley and BLP jets and was planning on starting with holley 98's plus a PV in the front and BLP 144's in the rear.

Good luck at the Gaters! Are you also running the divisional beforehand?

I'll try the other blocks one more time, but I think I'm close to all this carb will do on this engine. It is an 1150 on a 23˚ 427, and with the thin throttle shafts flows probably closer to 1200. I don't believe the boosters have a signal issue, just the engine being able to pull enough through them with it that large. Still a little quicker than the gas 1150 and cheaper on fuel costs.

As far as your 1050... I picked up some parts to work my 1050 over for E85 and will try it out soon as well, so I'll have some data for it maybe in a few weeks.

No to the Valdosta divisional, gotta work this Friday and Saturday.

Mark where did you end up with blocks, jets, etc on this carb? I just did an 1150 for a friend of mine with a street/strip big Dodge with a 512 wedge motor. He hasnt ran it yet but should be in the upcoming weeks. Here are the specs I went with on that one:

Blocks:
QFT Green 2 Circuit (Mainwells resized to taper from .172 - .187 at cross channel.)
Cross Channel .174
IFR .046
emulsion .028 - X - .028 - X
Kill bleed .028

The rest
Booster 12 hole resized to .070
Booster channels .184
Banjos with a 1.010 skirt (Wanted to cut GFM a bit on this one as the cam was not enough for the 1150 in my eyes)

MAB .025
IAB .060 (wanted to build heat quicker for him) May change to .052 if its too erratic in temp increase at idle.
TSJ .135
PVCR .082

PMJ 93 w/pv
SMJ 103

I am thinking he will need some more jet but I know this will get him in the ball park with his combination. I am thinking he will end up at 95 - 105. Time will tell as he is going to the dyno next week.

AJ, question on your crosswell (cross channel) dimension? You're .187 @ that crosswell in the mainwell but the crosswell is smaller @ .174?? Then you list the size of your booster channel through the banjo @ .184? Correct me if I'm wrong here but isn't the circuit suppose to get progressively larger as it goes from the MJ to the booster? Looks to me like your .174 is going to be a restriction in the middle of that circuit??

My 1150 methanol carb I'm building is going to be that way with a final banjo feed hole of .234 into a 12 .080 hole booster. I want to be able to run a .225 MJ so I'll need something that tapers up to the crosswell @ around .230 then crosswell slightly larger but not at or above the diameter of the .234 banjo?? I may have to have some special cutters ground to do this but I know of a shop local to me that can do those.

If I'm all wet here then by all means let me know cuz if this isn't important then I won't go to the trouble.

Similar to what I started with, be ready to throw some jet at it but the skirted banjo's will change that some. Right now I have the BLP 5130 blocks, 2 circuit for a small methanol carb. #3 taper, .184 at the bottom, around .200 at the top, .184 exit channel, .181 pins, .185 banjo passages and 16 hole BLP boosters. #2 ehole with a .024 and the rest plugged plus I think a .028 kill bleed. Jets are at .168 square in a BLP jet. I have no data as of yet on my skirted 1050, when I installed it I must have knocked off the throttle stop wire, trying to get it running with the stop closed didn't work too well. [-( Put the 1150 back on at the track and THEN figured it out, too late to switch back.

I got down to 4 cars again this week and gave the race away. My .10 to a .17, other guy was 2 over and I was on a 1 over pass until I tried to judge him AT THE MPH CONE. ](*,) [-( Ripped the throttle and then saw the other cone.

Ken my theory behind it is that my main restriction is still my jet size. I make the cross channel the same size or +.010 of the bottom of the main well. When it approaches the cross channel the smaller size will increase the velocity of the fuel through the cross channel and into the stake tube and booster. The greater velocity allows more fuel to flow through the booster than increasing the size from top to bottom. I may be off base on my theory as well but it has worked well so far.


Still no results from the 1150 as it hasnt made it to the dyno yet.

I just did a skirted 1050 as well. We will get the car fired up tomorrow and have it on the track in 2 weeks. (Not my car yet.)

Ken, I don't believe the larger mainwell to the angle channel will be an issue, although I believe the .174 cross channel is going to be small for an 1150. Having the mainwell a little larger at the top may help the transition or turn to the angle channel a little less turbulent. Skirts will help it a little and may be enough, but those metering blocks are similar to what I had on the 1150 and without skirts it will not be enough. AJ, one of the threads you may want to read is the bottom in the E85 folder is this one.
viewtopic.php?f=21&t=7055
It discusses the differences in ethanol's viscosity, and the reason to make sure transitions are progressively larger as much as possible to avoid sending the fuel turbulent in the main passage. It may be why the smaller blocks didn't work on my1150, I'll see if they will work on the skirted 1050, it may be that an 1150 is the point we need larger mainwells for. I agree that keeping the passage as small as possible will make the fuel delivery more responsive, as long as it poses no restriction like I found with mine.
