my b18b finally boosted
 

hey just got back from the dyno today. wasn't really impressed with the numbers, i was expecting more. does it look right or should i be getting more power? it was only tuned for an hour though.

my setup:
stock ls
short tubular mani
garrett t3 60/48 from ford merkur
38mm tial wastegate with mbc
dumptube to the floor
2.5 downpipe with 3" cutout
dsm 450
walbro 255
2.25 cold side and 2" hot side charge pipes.
8" jrc

spike up to 11psi at 4500rpm then drops back to 8 or 9psi till redline

190whp 191 tq

blue lines were my basemap run at 8psi

Looks good. A/F are very conservative and who knows what the timing is like. Bigger turbo, bigger DP, bigger charge pipe, more boost and a more agressive tune and you'd be sitting pretty.

does my power seem right at 9-11 psi?

Re: my b18b finally boosted
 

I would think it would be closer to like 220 ish whp but maybe im full of ----, def. a bigger turbo is needed, a .63/.60 54 to 57 ish trim t3/to4E is what you need my friend, maybe the timing isnt agressive enough, do you know what the timing maps look like when your in boost? top end timing? should be like 22 deg. top end, ngk 7's for plugs? gapped to .028-.030? pull a little more fuel out and get it to 12:1, i think with more proper tuning you could get well above 200 whp with that set up though....

numbers could be better
