i know 18psi has a scan gauge, perhaps he can letcha borrow it or use it or something, not monitoring knock eh? well as u said its been awhile since uve done pulls, ive been neglecting my knock for awhile, than i got home to the dsp and realize i had 5 degrees of it...5 minutes later...bam, nothing thru all 4 gears i tried, simple WOT spark adjustment, but for you, im not sure how you would stabilize ur knock out not having that cause ud be happy with ur fuel levels than ud have to cut them back to get rid of knock. gr...the shit is so time consuming, why cant i have a car like jose's where i put the parts on and it runs like a fucking stage 2 on an s0 pcm. good god.

LOL I hear you man. When I was on the dyno earlier this month I was dumbfounded.

265HP, 312TQ. Then one of the other Big Turbo SRT's went on and produced 350HP with only 322 TQ. How the hell am I producing so much TQ, but such shitty HP, lol.

If you were on a mustang dyno(loaded dyno) a 265whp output is close to 290whp on a dynojet dyno. As for the torque our little stock turbos are torque monsters because of their quick spool time. Some people have seen nearly 400ft lbs on their stock turbo when they crank the boost up to 24-25psi........the downfall of doing that is the HP output will be hurt because peak HP for our stocker is around 20psi. Anything more than 20psi actually hurts top end power, but man it can be fun to have all that torque

In other words you can add close to 10% on top of a mustang dyno output and that will equal a dynojet output which is likely where most of these 300whp guys have gone to get readings.

Damn really?! That makes a lot more sense if this is really the case!! Thanks for the heads up. As Scott said, it was a Mustang Dyno!!

Smart idea I think do to it was so much easier to respond to mods when I went to a bigger snail. You won't be the slow one of the group anymore with that

That is the actual Scientific factor WAY over my head.
I was looking for the correction factor to make the Mustang === Dyno Jet HP #'s more equal. I heard that you add about, ABOUT, 10% to Mustang #'s to match what a Dyno Jet see. IE Mustang #: 300 HP Dyno Jet would see 330hp 300 + 30 (10%) = 330

Just what I have been reading/hearing

Got yaa. I was reading on some dyno sheets it says 12% conversion on NA engines and 12%-15% on Turbo/Supercharged engines conversion on Mustang vs Dynometers. Mustang Dynos only use SAE factors only.
