YSI build about complete... results in.... I started this build thread a while back....
https://ls1tech.com/forums/forced-in...witch-ysi.html
The build is complete now and the final results exceeded our expectations.
Dyno on pump gas and meth.... 15 degree max timing.... right about 11 AFR.
IAT's were 135 on a run we did with no meth.....64 with about 70/30 meth/water.
I also checked the crankcase pressure and the MM cans are great. Basically neutral with no build in pressure at all.
We only made the pull to 6400 rpm. The next pull would have been to 6700 which is where I usually stop, but this was enough. I don't need the glory dyno sheet. Very happy with this.
We could have added a few degrees timing, leaned it out a little, and ran it to 6800 and been well over 1000...... but didn't see the need.
Seems our custom fabricated intake is working fine too.
Huge thanks to Seth at Federal Performance for all the help, and putting up with my fussy quirks. LOL. This guy knows his stuff !!!!!!!
Final numbers..... 983@6400 RWHP
817@6000 RWTQ
The green is my old eforce build....

Thanks guys....
This on 17.5 lbs of boost. The blower is not maxed out. Should be turning around 59-60000 at 6500 rpm here. It is rated to 65000 and can be overspun a bit with no problems. Plenty of room for more.....I would just need to grow a bigger pair.
