Not bad at all. I want my y8 to get 200whp too off my T3 .48/.63. I don't think I'll boost to 12psi though. 10psi for the track and 7psi-8psi around town. I'm going to run stock internals so that size turbo on my y8 boosted to 10psi should hold, right? I want to see the dyno, too. P.S. I like!!!

congrats scotty, your new motor setup sounds alot like what ive been planning on doing also. maybe we should do a twin buildup... vtec vs. non-vtec

i'm going to the shop tomorrow night...i'll post up the graph as soon as i get home.

checked my email and there was a present waiting. thanks for emailing the files charles.

if the boost wouldn't creep back to 10 from 12 i could've been in the 210's to 220 range.

whats with the AFR's? graph looks like its all 13's range.

scttydb411

it's aggressive in the low end...13:1 while it's transitioning. 12.5:1 to just above 12:1 full boost throughout midrange to upper end. i've run this engine tuned similarly to this for almost 2 years.

ok so the dyno is probably just using a sniffer which tends to be about 1/2 point off.

more than likely yeah, sniffer's just reading a little lean, i hate those damn things tune looks real good though man, good job!

it's in the downpipe...12.7 at 3.5krpms 12.5 at 4krps and 12.2 at the topend. it's hard to tell because i didn't put the red indicator line at 13 across the af graph. i may work on the mbc tonight to see if i can get it to hold.

yikes, a hair lean for my taste i try to keep afr's right under 12 anything over 7 psi, the .5 more fuel won't affect the power at all, and it's just al ittle extra insurance, for say a less than perfect tank of gas or some warmer charge temps on a hot day, etc. but too each his own.
