Just trying to figure out the new trans cooling system. He went with a thick cast pan that is cross drilled with water ports. We were hoping to be able to use the heater ports on the water pump to circulate the water but it just doesn't move the water fast enough once it's restricted down to the 1/8" ports. He's going to have to buy another pump now.
Ordered a new chromoly drive shaft with a billet slip yoke to replace the aluminum one with the regular slip yoke. The standard 1350 slip yokes seem to twist the splines once the 60' foot gets into the mid to low 1.3's with these heavy cars. I'm on my 3rd in the last year. This last Strange one lasted 2 high 1.2 60's.
He went ahead and got the big wheel studs for the back also as that was probably going to be the next problem.

Reaction time was of no concern last night. We just wanted to figure out the ramp for the 60'. Rome wasn't built in a night. Not even in 5 months. LOL. The car builds boost quickly but we haven't practiced prestage at all. Also, this car is not really setup for class racing. It is a street car at 3500 lb race weight. Full interior minus back seats with stereo and subwoofer in the trunk. There is no plumbing inside the car. It is very mild mannered.

Next order of business is a cold air intake contraption. Due to the orientation of the turbo's, he is picking up air that is 150* degrees to start with from behind the radiator. The other problem is that they are only 4" from the charge pipe which mkaes for a very tight radius. Too tight for a 4" 90* to go on there.
So what is happening is that the A2W intercooler is cooling the air charge to ambient at the starting line and by the end of the pass, I'm seeing 150* actual post IC charge temps. On one pass he forgot to turn on the IC pump and charge temps were just over 200*. So we know that the IC is knocking atleast 50* off what it is sucking in.
One thing to take into consideration is that the E85 is also cooling the charge before it goes into the cylinder. There is no way to measure what the real charge temp is but I think that if we can drop 50* at the TB, it may be good for another tenth.
