Enjoy !

We will be making alot more videos for his channel shortly. Stay tuned!

You gained ~110WHP from 2.5 psi??? WTF.....Didn't have audio on, was the tune fat/undertimed on the 12 psi pull?

Nice numbers man as always.

Will need to ask him . He started basically from nothing . So he was creeping up on the tune the whole time im assuming

Appreciate it !!

was creeping up on it, added about 3 degrees and added boost. I like to make it suspenseful

LMAO, that makes more sense.

Was that on gasoline or E85?

Like 70% content

walmart ethanol

was this the same car you had the NA 416 in? If so, which setup is faster?

Yes same car . Well find out soon which one is faster!

I have saw 40-50 hp gained per pound of boost on the Dyno it's not uncommon. Nice!

On what setup? I wouldn't call it commo unless your initial boost/timing is WAY off.

Considering the changes its not far off from normal at all for 3 degrees and 2.5psi to gain 110whp. Every degree of timing should pickup at least 15whp so your only getting like 25hp per lb for that 2.5psi increase. Seems like a lot at first glance but once you break it down its pretty normal. I've seen a lot more gained from each change, just depends on the setup. That's not even factoring in if their was an A/F change but normally the power doesn't change all that much as long as A/F is close.

If you guys read my posts again, I asked was the timing/AFR off on the pull with 2.5 less PSI....then when subeone confirmed that they also added 3 degrees of timing I said it made more sense.....I've never seen 110whp from ONLY a change of 2.5 psi assuming AFR/timing was good to begin with.

Gotcha, 30-35 isnt uncommon on big turbo high flowing stuff but that's still a bit off from 110 as you said. Sometimes you can swing A/F a half point in either direction and not see much if any hp change so that's probably the least important assuming its already in a safe range.

Agreed. 30-35 is what I expected, hence the question. Adding 3 degrees can add 100whp by itself in some instances so it made more sense after subeone clarified.

Have another fuel pump coming . So hopefully we can stretch these injectors out a bit more and make 700 ish with them .

What fuel line are you running? and what fuel regulator?
