What would the power output be?

Car : Polo G40
Mods : stage 4 charger
65 mm toothie kit
Fast road cam piper
Bosch performance plugs
Magnecor leads
Gt inlet
Panel filter
Chip from PPP
Exhaust system

Any ideas ?

150 - 160.

I know you've not asked what you can do to improve...
But a de-wedged throttle body or 51TB from Justin would be a good addition
You also haven't stated that the OE restriction in the plastic airfilter box has been removed, this also helps.
I don't think going from stage 4 to full blend would make much difference.
Otherwise it sounds to me you've got quite a quick G

I would have said 130-140 and 115 at the wheels

My g40 was same spec minus the cam but de wedge tb and i made 149bhp

O right , well they reckon a 15bhp increase on piper but very wary of that increase, I had de wedged on a gt however running was a bit lumpy and un even never got it running right.
Wouldn't mind a bigger TB but quite pricey , found top end restricted so hopefully a system will illuminate this.
The triangle part of the airbox that I can see is in the bottom part itself but can't see how this will be a power gain , wouldn't also mind bigger injectors but then have to start to think about clutch's then.
Hopefully get her into a RR soon to see so others can use it as a guide!

i went from 149 to 171bhp+ with 1341 bottom end, gas flowed head, cam and 51mm tb. I'd say you'd get around 10bhp from a cam. They claimed a 15bhp increase from my schrick one but that was probably the best figure they have seen. I'd like to run mine on a standard one to see what power decrease i get.

For the clutch just get a helix ceramic one. Will handle the power fine, has done on mine for a while.

Mine made 136bhp and 139lb/ft with a full blend charger, 68mm pulley, decat, de restricted airbox and GT inlet (plus a remap). I'd say 150, maybe more, with that spec.

I ought to get mine on the rollers again now it's got toothed belts and a PPP exhaust.

Yeah mine had headwork, piper cam, 65mm pulleys on a full blend and dewedged the TB as well as GT inlet and i got 108 Bhp at the wheels, though when rebuilding my pistons looked like they had a fair amount of blowback.

Will be getting it back on the same dyno just outside Pickering once i have run it in
