Re: homemadeturbos suck?? wha'what??
 

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. ;) ;D 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 :)

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.

Re: homemadeturbos suck?? wha'what??--now w/ dyno graph
 

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!

Re: homemadeturbos suck?? wha'what??--now w/ dyno graph
 

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.
