yep, standard gearing 400 (2.48 /1.48/ 1.00). Slick is a stiff wall 28x10.5" and 3.25 rear gear. The thing about this pass, after looking at the logs, is that it really wasn't that great of a pass. The obvious slow launch because of tires but I also had not adjusted my shift light from last yrs stock LQ4 so the shifts were all around 6000rpm instead of 7000. Not sure its worth much but def worth something (hp curve is still a 45* incline at 6000rpm).


We had no issues at all at 27* and 3.6 AFR, but is it is only 12 psi. I'm told I will have no issues below 30psi, I don't plan on going over 24 psi. I guess we will see next yr.

Nice build! I like the white
How does that swaybar crossmember work that you made up, is there any significant improvement? Is it connected to the stock swaybar?

It's just a homemade double anti-roll bar. It actually replaced the old solid ATR sway bar that was connected to the lower control arms. This bar connects the body to the rear end so they stay "in sycn" with each if that makes sense. If you look at how twisted the car is in the pic in my sig, the new Anti roll bar eliminates that 100%. Now when launching the car the rear end and the body of the car stay parallel with each other. I will know more after some good tires and more testing.

Don't they have websites about that?

Wow! That's a bunch!

Well little update ... upgrading the front brakes as this boat didn't like stopping from 149. So I picked up the Dynalite Pro Series Front Brake Kit from Wilwood to help fix that problem. Should be installing tonight and hoping to do some real testing soon with new tires which are mounted and ready.

Updates to come.

Eh not really. That turbo isn't doing anything at 4#.

4#? What do you mean? It was 12psi & 3.6 air fuel ratio on that pass, 19psi on the dyno.

Ok, little update. Below are two pics of the new front brake setup. These are awesome BTW!

I was able to make 3 test passes to start working on ramping the boost in. Everything is still new; new combo, new slicks, and now testing at a new track, so I baby stepped the boost just to see what it was going to do. With a 5psi launch it did a 1.400 60ft and the ramp very soft at 5 to 6psi in first gear and up to 10 to 11psi in second gear (just hit the 7000rpm rev limiter as I passed 1/8mile). The car ran 6.13 @ 116.87mph. I'm happy with that and how the car felt. Next testing will be at the first race on the 26th. Planning on 7 psi launch (see if it holds) and then get to 15psi in first gear and 20psi in second gear. I guess we will find out soon enough.

nice numbers. my car ran high 5s with a 116.92 mph so you are already making enough power to be in the 5s even with the soft ramp and low boost.

Thanks. My biggest obstacle at the moment is the stockish susp on the car. I'm hoping I can get some low to mid 1.3's with it turned up a little more. Next time out i'm gonna try to ramp it in much faster too. At this point I'd like to see some 5.7's or better. We will see on the 26th.

Seems quick for the amount of boost! Methanol ftw!

methanol is an amazing fuel. i wish more race only guys would catch on and see the benefits of methanol

BMF_Racing

iTrader: (6)

It is slowly catching on more and more recently. Def alot more out there using it on turbo cars now than a year ago.

3-4 bucks a gallon
can save about 100lbs in weight off the car
detonation resistance like a mojo
runs cool
cleans the piston tops
can run almost max timing
more power and TORQUE

yeah, for me its methanol or nothing at all.

BMF_Racing

iTrader: (6)

Yes Sir, all that for the cost of a bigger fuel system (only con I dealt with switching). I'd recommend it to anyone for their race car. Pro's overly outweigh the cons for sure.

Methanol is great. I use it as a add-on in my car. If it were strictly a race car though I don't know where the gains would be over all of the other race only fuels used already.

Well had the first race for the local "street car" series this past Sat at the oldest track in the US, Thornhill Dragway. Even though I didn't make any clean passes, it was a good time.

I was able to get out of the gate ok but the .400 pro tree caught me off guard so was only launching at 3psi (don't have any real spoolup tuned yet as the event was to be an arm drop race which is much slower). It was good on these passes till about 20ft out when it ramped to 10 psi, it would move aound a little and calm down in the bottom of second gear. As it ran though 2nd gear it was breaking traction the whole pass (but pulling good) and then would get way out of shape in the top of second gear at 13psi and have to lift (no full passes all day) letting him drive by me while I coasted through the 1/8mile (was way out on him, oh well). It really was all over the place to be honest and even with all of that I still had my best 60' with the car ever, 1.368.

I'm stuck at the moment with the susp I have, gonna work on the stuff I know needs attention first (solid things up in the rear ... control arms, so on) and see how it goes. I'll be doing a full TRZ susp upgrade over the winter. Even with all that didnt go as planned, I had fun and will continue to try to dial this heap in and get it to run as good as I can with what I have, I guess we will see.

Little Update:

Well race #2 is done ... and making ground on the tune (made a new PB 60' for this car, 1.352). I was able to get a launch procedure setup so I can be at 3.5psi on the footbrake at pre-stage and creep into the stage lights on the 3step and stop it with the Tbrake as soon as the 2nd bulb comes on. It instantly is at 5 psi, ready to launch.

Both time/qualifying runs it still unloaded the tires in second gear, even with all dome pressure set to zero. Just before 1st round, as a last effort, I went in a pulled 8 to 10* timing out for 5psi and up across the entire ign map. The car spun on launch, 1.516 60', but went straight down the track effortless. It felt ok till about mid-way through 2nd and then 3rd ... man it was a pig up top without that timing. The other guy crossed about a car and a half in front of me so I lost but didn’t care much about that as I was just thrilled to finally make it down the track. It ran 6.301 @115.8mph. I plan on creeping up on the tune until it starts to spin again, then I guess that’s as good as it will be until the new Susp gets here.

I used to have an 87 GN from 87-92, got it running low 10s full weight, A/C etc.
Now I'm building a 1964 Chevy C10 pickup using a single or twin turbo on a GM Performance LSX376 B15 (4 bolt mains, 6 bolt heads) Will run the alchy control methanol system all in a 64 Chevy Pickup. Not sure how much boost it'll hold, should be a beast. Ford 9 inch, tubbed, 4L80E tranny. I'm new to this forum. Just trying to find the best ideas, anyone have experience with these motors? Which intake would be best? Looking at the Holley Hi-rise. 95-100lb injectors and hoping to make somewhere around 900-1200hp. Any ideas would be appreciated. Also, what about exhaust manifolds/headers. Looking at Stainless works I guess and finish fabricating the rest. Maybe get the ones that go up and forward because I'll have lots of room under the hood.
