Donnie,

Is that a real HKS gate or the knockoff? How do you like it? I use a 50mm knockoff that rusts and sticks when the car sits for a few weeks. It probably just needs a good reeming and antiseize but I'm wanting to upgrade.

John

That is awesome. I didn't know that Jesels made rockers for the stage 1 type heads.
What turbo is that to go that fast with 22psi? Must be some low backpressure in those headers!
 
Don, I thought you were doing up a TA AL block?
The timeslip for this thread was done by the Alky Buick V6 version 2.0.0.
The latest Alky Buick V6 version is 3.1.0. It is using the TA block. Version 3.1.0 is the one in the picture on the first post.

Actually, the boost was unstable and had dropped to 20 psi by the end of the run. I haven't figured that one out yet. I'm kind of thinking the turbo just didn't have enough flow to keep it up.

The Jesels are designed to be used on the M&A heads. Pushrod holes needed to be modified. I installed a set onto a customer's TA SE heads with a little modification to the mounting bar and pushrod holes. Worked out great.

Old school Turbonetics T76 (not the Super)
Single ball bearing
Q trim
.96 AR ratio turbine housing. Carefully ported to match exhaust system flange.
V-band clamp
4 bolt mounting flange
The compressor housing is from my old T70 that I modified to fit the T76 compressor wheel. That...was interesting.
Electronic boost controller by Innovative Turbo Systems.
HKS GTII 60mm wastegate.
Turbonetics Godzilla blow off valve
Intake manifold mounted, DRW designed poppet valve for max level boost control and protection from intake backfire.

Don,

What RPMs do you go through the traps at?
I really think the car would pick up with either lower numerically lower gears
or taller tires. Let me know what you think!

We have 3.7s in Chows and run 175MPH with no second half of the track.
We would have put 3.6 or 3.5s in it if we had to do it again.

I was wondering if someone would pick that up. Very good John. I'm impressed.

My shift point is 7400 rpm. The car goes through the traps at over 7800 rpm. You are absolutely correct about the gearing or tire size. I haven't figured out which way to go yet. More time on the sim. My home track is an 1/8 mile track, so at this point it's not real important to correct.

Don,

Thanks for the compliment I will take any I can get!!!:D
You may be able to correct this with a 30X10.5 but I think I would
prefer you stepping the gears down to at least 3.73s
That would really help you launch the car with more boost as well.
We should be able to get your 60s in the 1.35 range at least!
Please let me know what you decide to do.

Actually, when I first installed the Moser rearend, I had it setup with 3.73s. I went to 4.11s in search of improvement. I'll have to look back at the timeslips, but as I remember it the change was not a big deal. Within a tenth for the whole 1/8 mile. Sixty foot difference in the high hundredths. The lower gear did seem to get the turbo to speed quicker, especially without the nitrous assist. I had also changed over from a 200C I was playing with (and now am installing into our street/strip T-type) to a 400 transmission (higher first gear, lower numerically) at the same time I had changed the rearend gears. I was somewhat surprised that the difference was so little. I should also add that a sim I use also predicted very little change.

I've never loaded this car heavy on the boost at the lights yet. Mainly because I've always been refining the tuneup. After I'm happy with the tune, I'll start playing with different launching strategies.
