my 5sfte 200+whp dyno runs, 203whp 246ftlbs! Options

[presure2]

ok guys, went back to the dyno with the 460cc injectors, and did some runs to see what was up....first couple runs were about the same as before, about 195 or so whp and a little over 210ftlbs...but now it was NICE AND RICH, which i was VERY happy about.
so, i removed a little fuel up top (between 4600-6k) and upped the boost a little bit, to 12lbs.
she responded by giving me these runs.



after looking at the runs some, you can really see how the power drops off right @ 4450rpm.
i think this MAY be one of two things.
the SAFCII screwing with my timing, and the ECU making it pull timing to fight back,
or just plain ole detonation.
now, i havent noticed anything strange as far as readings on the SAFCII, and i havent actually "heard" anything strange, yet. then again, they do say by the time you hear it, its usually to late..lol
so, im planning on going back, and trying a few things to see what i can do about the power dropoff.
even with it, the car pulls HARD, and by the looks of the egts things are actually safer with the bigger injectors.
i really think that if i can figure out the issue i have there above 4400rpm, i should be making about 225whp to go with the 240+ftlbs...
any thoughts???
lets hear em!

Great numbers. That's weird, though, that at only 12 PSI you are possibly detonating. I run 12 -15 PSI on my Celica with Mazda MX-6 turbo injectors on Shell 93 in the hot ass Puerto Rico weather and I have never detonated...I am trying to make the engine break so I can know the limit of it before beefing it up but it has held all the abuse. =/
