1) Sierra Sierra evo8 putting the Full-Race twinscroll through its paces during a practice session at Buttonwillow:

2) A hardcore Subaru customer of ours has a Full-Race twinscroll 40R turbokit on his daily driven (literally) built STI. He loves the spool, response and power but wanted to do a similar build to an Evo. He bought a low mileage evo8 from a close friend of ours, and decided to stay with the twinscroll turbokit to retain good spool and quick response, yet still looking for 700+HP. He used a simple but intelligent build with a top notch parts list. The first day of 93octane pump gas tuning was very impressive... resulting in 641whp/526tq

As a fellow GT4088 owner myself I am impressed with the results once again. Did you post the boost somewhere. I was unable to find it.

Going over the list we have just a few parts slightly different but for the most part they are identical.

Congrats.

Nice! I love in-car vids. How much of power is that Sierra car putting down?

Thanks for posting up the 93 octane pump gas map Geoff! Looking forward to the race gas map!

The AEM logo and the corresponding dyno chart were posted by Geoff - 27psi...

Jeff Evans and I agreed, 640whp is more than enough for 93 octane pump gas... Race gas tune and more boost should happen in a week or two...
