Aftermarket throttle body and STD cast iron exhaust manifolds with aftermarket 2 1/2 inch dual exhaust system.
Do have any before numbers? when I installed my Roe I gained 150whp and just over 100ftlbs, but it was different dyno's so who knows
Before I bought it, the previous owner had it dynoed. It was on a Dynapack chassis dyno (NZ designed and Built). 551hp @4950rpm and 852 Nm @3932. It now has a tune from Torrie and goes hard right to 6250rpm. It will be interesting. It will be on a Mainline Dynolog. Anyway it will be a fun day out. Just been reading.....Dynapack and Dynojet read same ish, high. The Mainline Dynolog is approx 15% less, so DON'T expect too much
The ROE was installed in January 2005 within the first month of the original owner buying it in Alabama.
