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!

Wow Manny. That graph is so close to my 3sgte graph (before the turbo upgrade) at 14psi its scary. Perhaps you don't even need the 3s! Here is my plot:

haha jay...naa..the 5SFTE is fun, dont get me wrong,
but with the setup that im running, im really pushing it..lol
boost control has been a problem since day one with the '27 and 3" turbo back.
it pretty much just rises right till redline, and on a normal day will peak at around 12 or so lbs.
i think the fact that i have the super fresh '98 motor to start with the metal headgasket ect has really helped me a ton, i totally believe that if it wasnt in as good of condition to start with, it'd be dead. lol
the 5sfTe can be a great learning tool, and it has been...but its not what i wanna do with it.
the 3sgte will allow me to reach my goal for the car MUCH more reliably, without question.
with the '27, and a few simple bolt ons, i can easily surpass 250whp, which IMO is more than enough for my needs.
besides, with the wifes heavy right foot, and her 40mi commute round trip everyday we need to keep the car helthy and reliable, somthing much easier with the 3sgte VS 5sfte..
knock on wood, i havent had any MAJOR problems with the 5s yet, but thats just it, its all about that magic little word : YET.. haha
its not a matter of IF, its a matter of WHEN. IMO thats the rule for 5sfTe projects, and when bryan "noshoes" moore tells you that very same thing, you better listen..hehe and i have.
that said..
IM COMING TO THE DARK SIDE JAY!! hehehehe

ohhh..and lets not miss the fact that in your graph, your over 200ftlbs till like 5600, and 200whp well past 6k hehe
