Looks perfect. But why such low Boost/High Octane??

 

[FourG63GST]

Thats what I wanna know. You could get away with more boost than that on PUMP.

 

[UNDR PSI]

im running 100 right now because next thursday, it is getting dyno tuned for 28psi, on 100 octane. The shop that is doing it, told me to run 100 octane for a few weeks before the tuning. Ive just been playing around with the tuning the past few days for the hell of it. Timing looks good though???

[markgholland]

Now tune for knock What does the butt dyno say you make for horsepower? :laugh:
~Mark

 

[UNDR PSI]

what??

 

[markgholland]

What are you "what???"ing? Tuning for knock?

When I said, "What does the butt dyno say you make for horsepower?" I was asking how it feels? Are you satisfied with your 50 trim?
~Mark

 

[mavisky]

2g's can't see knock, poor bastards

 

[UNDR PSI]

thats why i said what...the knock thing. I have to go off timing. It pulls hard, even for only the 16psi im pushing now. I love the 50 trim....and to think its not even effecient until 18+psi. As it is now i walk all over z28's and hang with c5 corvetts. Im getting it tuned for 28psi thursday and i cant wait to see the HP on the dyno with that, let alone the"butt horsepower" Im sure i will be much more inpressed with what i feel vs. what i see. Thanks for the replies.

[markgholland]

2g's can't see knock, poor bastards

But he can see timing retarding...
~Mark

 

[mavisky]

yes, but that's still not the same thing exactly.

 

[markgholland]

yes, but that's still not the same thing exactly.

You're right, however, the onset of knock is present by the slope of the timing curve. So in essence, he *could* tune for knock

Whatever, he'll get on the dyno and tune it with a WB. Problem solved, done deal.
~Mark

 

[KPWSerpiente]

I am quite capable of seeing knock in degrees of timing pulled and in raw counts. Yeah, it's a 2g...


The log looks ok but you'll probably love it more at 28psi.

-T

 

[UNDR PSI]

yea in essence, you can tune for knock if u think of it that way. Because anytime your pulling timing a decent amount there is knock. Were all right.

 

[Violater101]

Good Luck with the dyno ... why again did he want you to run 100 octane a whole week in advance again? Aside from making sure that you were completely empty of regular gas. How are your EGT's? That should give you a good indication without a wideband of how lean you are.

 

[kpt4321]

I think 28 psi is probably on the high side, why did you pick that number?

I think 25 psi sounds a lot more reasonable.

 

[UNDR PSI]

Well the shop told me it would be a good idea to run it for a bit before hand. My EGT's are good, around 1500 at top of 3rd and hold steady. I get the car back today, cant wait to see what she can do. And i picked 28psi, because that turbo can handle that all day long. Plus with all the time and money i spent over the winter building this car, 25psi just wasnt high enough. The car is built to handle 600whp, and the turbo is capable of 28+psi......so i figure i got it at hand, why not use it.
