Its been a little over a month but I thought I'd post my results since Im changing a few thing and going to re-dyno soon.

Keep in mind it was 97* outside during the time of dyno in mid July

Excellent results. What is the CR with this setup?

1 BAD BURB

Nice!!! That must be a 12.5:1 CR? I bet the thing is a blast to drive.

C6 Curtis

Thanks 13.8.1 because of the .130 mill, I had to use 7.700 pushrods compared to the 7.800 before the milling.

Very fun to drive. Just need better tires now NT05R's spin from a 60 roll. Ill post an idle clip tomorrow.

Good numbers

Brandon619

13.8 compression! That's what I'm talking about, great numbers.

LS7 BUD

Great results...! I'm jealous of all the guys with E85 available to them... I make 624rwhp & 555rwtq on 94 pump and meth at 12:1cr... I would love to see what I could make at 13.8:1 on E85...

Da Z06

Sick! Great numbers!! Now get her to the track and get into some 9s!

Whis9

Awesome
Great numbers

Looking forward to some video. I am looking at going to E85 right now as well. Are you running cats?

HyperX

Stupid question - but if I do this e85 conversion (which is rock solid) does it down tune itself if I pump regular gas into it? (You know go on trip where there are no e85 stations)?

FNBADAZ06

You would need the flex fuel modification offered by DSteck to have the car adjust automatically from pump to E85 fuel. I currently use HP Tuners to upload the appropriate tune for the fuel I'm running.

Are your dyno numbers SAE corrected, and with smoothing set to 5 ? Your numbers are impressive with 12:1 ....you're running the BTR Stage 4 cam, correct ?

FNBADAZ06

Do you have a dyno sheet with SAE correction and smoothing set to 5 ?

lane_change

I knew someone would eventually have to be the ******* to ask for that.

Don't worry, I thought the same thing, but decided to keep my mouth shut.

FNBADAZ06

LOL I hear ya.
I'm not trying to call the OP out or questioning his results but it's a bit easier to understand the mod's to engine output when we all use a common setting.

I have the Winpep Dynojet software on my laptop, and when I change my SAE to Standard, and Smoothing 5 to Smoothing 0, I pick up 12 RWHP and 12 RWTQ on the same dyno run file

C6 Curtis

Unfortunately I dont. The car did trap 139 last month so its pretty much on point. I had a crap e.t due to wheel hop out the hole.

Lawdogg

Doesn't that depend on the temp, humidity, etc. On a hot day won't sae read higher than standard?

FNBADAZ06

No worries.....and I agree, 139 traps are on point for 600+ RWHP.

FNBADAZ06

Actually, correction factors are used to mitigate MOST atmospheric conditions which can affect the dyno readings. What the correction factor can't do is take into account what knock retard or A/F ratio changes are doing to the engine, which then affect the final number. For a more complete picture to be presented, you'd want to see the correction values AND the IAT's, ECT's, A/F, and KR-timing numbers.

And, more to the point of your question, STD correction factors will always show higher returns than SAE, as the formula used are different and biased to a higher output with STD correction. The only time you'd see numbers HIGHER than a corrected number, regardless of the correction factor used, is when the dyno run is performed in conditions where the DA is way below sea level, with crisp, cold, dry , air.
