106mm turbo . Hello ,
I have motor that jusy finshed and its for drag race only ... so what i need to know is what size A/R that every one is using for that kind set up .
the motor is :
436ci lsx block
etp 255cc heads .
wet sump kit on it .
sold cam .
and do i have to use two 60mm W.G so i can control the boost right on it . or just one 60mm will be fine with it .
and what is the best gears you are using for the 1/8 mile i have 3.55 right now on my M9 rearend .
Thanks for the help .

We just talked with Precision on this. The recommendation is 1.32 for a footbrake car. It will spool faster. They did say the transbrake car can take advantage of the 1.50 AR depending on converter and RPM range.

Verdad Gallardo On a 427-438? I highly doubt you'll see anyone running a 1.50 AR and going fast with a 427-438". Maybe on a 525-550" big block.

Tuna, a 1.32 is what you want. I would stay with the 3.55 as well. We run a 3.50 with a 315 radial with a 3spd. And are near the top of 2nd in the 1/8th.

I've got twin 44mm gates and can run the boost down to 4# without any creep. If you set the wastegates up correctly you dont need two 60s. One would probably work IF setup correctly.
