m sure most have seen this car on the forum but the numbers are amazing!!!!!!!!!!!!!




593 rwhp with a TPI, ported vette heads and T-03 turbos with 2.5" downpipes.............holy cow.

Seems like the PITA Super Ram with the right cam could eaisly make over 600 rwhp.

I sold the brodix top end kit and actually lost $100 in the investment...oh well.

Can these turbo's fit under the car and support a SuperRam with ported afr 190 heads?

Im still learning about turbo effiencies so forgive my ignorance.

That set up with a SuperRam and nice heads would make a lot of power. The TPI made gobs of torque. Those #s were on 20 psi. at the dyno.

That is pretty much my engine combo. SR and AFR 190 heads.
I am looking into a 383 or 406 with the brodix 227 heads.
I am planning on moving up to TO4B's and try to get a bigger down pipe in there. at the least try and squeeze a 2.75, but I want a 3"

Pics of the headers? email me.
I dont get to be on the net much anymore.
Just a note, that was EX-gold87 setup.

talk about a well built system. He could probably find a way to route the intakes for the turbos up front by the air dam and get some colder air in there rather than pulling from right in front of the motor and gain some power that way as well. Other than that, that is a very well done system. I would like to see something similar done to an LT.
