It’s cool to see what you’ve tried and what the result was I love that and marks car was a monster I met him at island awhile back when he had it cool dude to talk to and was partly the reason I built my car

SOB!!!!
It's been bugging me why the added timing after peak torque actually lost power and the answer was right in front of and I didn't see it. I have MAT retard set up with 0 degrees retard at 150*F and 2 degrees retard at 180*F, never thinking the MAT would see 150* much less 180*. Well, it went over 150 just before the 2-3 shift and kept climbing to 170.5* at the finish line. So, instead of advancing 1 degree, it was retarding after the 2-3 shift and up to 2.33 degrees less than what I wanted at the finish line.

Been a little busy this, but here is an update.
7-sec pass didn't happen and didn't think it would since I tried on Sunday on a nice mid-80s sunny FL day. Faster I tried to run, slower it went and gave up when the IATs got into the mid-180s and turbo refused to give up another ounce of boost. Spoke to LJMS (thanks!) and he advised instead of the 1.58 hsg, that I send the turbo back to Forced Inductions for a 100mm turbine wheel and have the 96mm hsg CNC'd for the bigger wheel and better flow. Waiting for it to return. Didn't want to do that but would go bat-**** crazy to be so close and stop trying. That noise you hear is me drumming my fingers impatiently.

Don't know, Mark, and didn't ask as I not looking for that much more. Jose at Forced Inductions says the 100mm wheel is a new design and they have found a way to CNC the 1.32a/r turbine housing to improve flow while retaining the quicker spooling. Both Jose and LJMS said this was the better option. To be honest, there's only so far I can with 1400cc injs and twin AEM380s on E55 and the next worry is lifting the head and pushing water. Don't really know how far you can go before that becomes an issue.

40F temp drop should be good for 80ish hp.

Been a while. Sometimes life gets in the way of having fun.
Decided to make a radical change in my setup and simplify it. I eliminated the alky setup (it's for sale if anyone's interested) and decided to shoot for a 7.9xx with just C16 then back it off and run E70. Looks like I underestimated what it would take to tune going from a E85 mix with alky to pure C16 and also deal with a bigger turbo hotside. I've made 5 hits so far and the biggest issues I'm dealing with is spoolup and boost ramp and the fact that I like to take baby steps. Before, I was launching with about 3800 and about 25* and that got me 8+psi and now that could barely get me 6psi with a slight drop on the hit. Takes .250 secs before it starts ramping. Well, on the 5th pass I was up to 4380rpms and 30* and that got me 9.1psi and a wheels up 1.200, another 8.09! but 169.13, new personal best.
Still plenty tuning to do to see what AFR and timing it likes. IAT was up to 168* but I expected that and I am not seeing any signs of detonation yet but there is definitely more heat further up the threads. Gonna try a 8 plug and hope the NGK resistor boots work.
