Car goes on the rollers tomorrow, but Delta Dash Road dyno is showing it as producing about 470BHP/490LbFt.

Once the Sprint is over Owen is going to do a write up on the turbos and start marketing them, even before this last sprint we have guarateed a 1-2 in the championship, it's just a case of which of the two of us wins. (We have two cars with this turbo at the moment, mine is a forged 2.1 in a full weight JDM STi genuinely daily driven 12K mile/year road car, Pauls is an MY03 lightened Spec C with a stock engine.)

Wastegates on this Owen Turbo are inconel specials, one of the issues with the stock turbos is the size of the waste gates and the materials, it's not uncommon for the waste gates to not shut properly due to distortion and they can be restrictive at the top end due to their size. Uprating the actuators isnt actually fixing the fundemental problems with the stock turbo's.
well i hope its not too damn expensive after conversion rate for money and shipping. the new efr that is coming out is supposed to be super fast spool as well with the best technology you can get. i would just need to get a 1.5 scroll up pipe and mod my DP which is no big deal to me.
