abit lower on power but i didnt expect going from a standard one to a dyno dynamics to prduce the same power..
so here are the results.
140.1bhp @ 5750rpm (bhp)
115.0bhp @ 5750rpm (whp)
AFR dipped below 10:1 so its running very very rich... he said ti i sorted that out then id be looking at 146 - 147, but if i do remap it to sort that out and put on a 2.4 inlet and 68mm tb then it will run too lean.. so im going to leave it on standard map for now, get the engine bits i want then remap the whole thing once ive put on what i want.
the other vx220s were getting 156.8, 158.0 and 158.1 they had the manifold, cams, sports cats, etc etc.

Chris is a 2.2 16v, other engine is 2.0 16v Turbo Z20LET. I think book figure for the 2.2 is just under 150bhp and just under 200bhp for the Turbo.
Not massive power but the cars only wiegh 850 and 930kgs respectivly

a 2.2 NA and a 2.0 turbo
the 2.2 factory produces 145 at fly from the factory but i dont know how accurate they are.
and i dont know myself if running this rich would effect it too much, paul seemed to think another 7bhp maybe from the car.. if it was mapped to suit.
that means closer to 150 and thats not too bad, specially when all i have done is removed the pre-cat and ported the throttle body, none of which are bhp gainers but the curve is smooth.

result seems normal for a DD dyno, they usually get around 145-150 bhp. As you have pointed out, it is running very rich!
