where as the turbo is a better delivery of boost.
Charger definately has a better delivery than a turbo in my opinion.
Anyway, here are my thoughts, years ago on a stock car with stock cam, cat, exhaust, inlet etc, just a 65mm pulley and a chip pulley I remember pulling 150hp....
Now, no offence here Robin, even if it would have pulled the 10 more later on with just a map, something must of been up for you to pull 166 with this spec...
"1341cc
High compression ratio with metal head gasket
GT inlet
51mm throttle body
FMIC
Aquamist
250cc injectors
Full PPP system inc 4 branch "
Lack of BVH/Cam + large bore manifold? I don't know... But it is a bit harsh on that mateys for sale ad to tell him it'll only pull 140, he should get more than that, even if 180 is a bold claim.
Does anyone remember Jabbasports G40? Wasn't that 180hp? I can't remember the full spec, but it definately didn't have a large bore manifold, High comp 1341, FMIC, and Aquamist...
Personally the jabba car always said to me there wasn't much wrong with the stock intercooler and manifold/downpipe. This tallied up with the various G40's I've built and other people's I've driven. The car's I remember having more fun in had modified stock downpipes and smaller bore exhausts than 63mm. That's rated for 220-250hp?
Vaguely remember someone taking a high spec g40 to 8krpm and getting 200hp?
G40 with G60 lader making 221 years ago?
Anyway, just food for though for all you with G40 laders chasing HP, be interested to see some more RR graphs with full specs......
