Hi All,

Given my GC8 has all the work done below, why am I only getting 295 BHP at the wheels ?
I'll have to dig out the dyno graph as it shows torgue, put it somewhere safe, LOL. (ie Can't Remember).
Given the mods below, would you expect more power, or is the power output consistent with the mods done ?
295 bhp would be on normal RON98, with nothing added.


ENGINE
JDM EJ20 rebored to 2.2 litres
CP Forged Pistons
Eagle Conrods
ARP Head Studs
Port & Polished Heads
Walbro Fuel Pump
800cc Injectors
Greedy T518Z Turbo
Haltech Platinum 1000 ECU
FMIC
3" Stench Pipe, Turbo Back (no cat)

GEARBOX
Now has an STi 6 Speed Manual Gearbox, as the 5 Speed Close Ratio gearbox had a few problems

 

Seems like a normal power output for an 18g based turbo - Newer style/versions of this in Australia do 200-230awkw on 98 (Dependent on which dyno is used).

How much boost are you running?

If you want more, throw a Blouch 1.5XTR / SC42 on!

 

Seems like your turbo is the only limiting factor. Everything else is in place for bigger power.
Still would have thought you'd have gotten a higher figure imho.

 

Need to pull out the dyno graph to see what boost was.

Might have been a warm day, with no air cooling thru the FMIC.
