G40 Engine

[G40jamie]

Bought this G40 engine bout 2 months ago, been told it has around the 180bhp mark, what are the chances of this? As far as i know is has a stage 5 Charger, polish and ported, Stage 2 re-map, smaller pully. They since owning it i have done, 4-2-1 manifold with full de-cat system, K&N induction kit, freshly rebuilt, front mount intercooler. What break shoud it be running roughly you think?

150-160 on some decent, accurate rollers.

180-190 at stealth LOL

well it really depends what is meant by "stage #".  What is a stage 5 charger and what is a stage 2 remap?  What's been done exactly?  Also, what size pulley?

I doubt it's much more than 150bhp really.
