small update on mine
So, i thought it was about time i got this up for people to see..
my car (totally standard) got 140bhp and with the following mods its made 167bhp
Ecotec 2.2
K&N Induction Kit <- £80
Ported Throttle Body <-£free
2.4 Inlet Manifold <- £170
Comp Cams Stage 1 <- £240
Tullet 4-1 Manifold <- £488
2.5" Piper Downpipe <- £287
2.5" Piper Backbox <- £550
RS Tuning Remap <- £299
Total = £2114 (works out at £79 per bhp)
here are the graphs
after the mods (red line) and remap (green line)
as you can see you certainly loose alot of torque with the 2.4 manifold but! after driving a standard one directly next time mine, you dont really notice the loss even tho it is there and on paper it looks massive.
I am going to put the 2.2 manifold back on to see what i get then.
