made 320KW at the wheels or 430rwhp on 98 pump fuel here in Aus, they said should get another 15-20KW at the wheels once the limiter is raised to normal (Previous was 370HP with the standard stillen gear and frozen boost heat exchanger with a custom tune on same dyno).

So here's the questions as I'm going E85 straight from here;
If I change these 2 pulleys which I've seen some people do and pulling 650-700rwhp, what Belt will I need to run? - https://www.summitracing.com/int/par...-300/overview/

Also, has anyone upgraded to say a Nismo oil pump/aftermarket pump and raised rev limiter?
