I told them to stop at 9.5 psi cause I did not want to push it anymore. My initial goals was 550whp and I was more than satisfied with what I made.

Why is it that some people are getting 609 whp and 9.5 psi, 590 a 9.5, and 560 on "low boost" but then I see others in their sigs that are sitting at 540 at 10psi? I know it's components and tuning, but damn that seems like a huge loss for just specific selections you make? Especially when the 540 whp has AAM TT kit and their exhaust :/

Could be a lot of reasons. Weather conditions, dyno used, type of exhaust (true-duel, y-pipe, etc.) and most importantly the tuner performing the tuning. Some tuners are more conservative with their timing and that will have a dramatic impact on HP numbers.

also some people ask for the car to be tuned certain ways. some want max power as I would and some just want a little extra.

Also I would add the fuel system (injectors, fuel pump, rails, return lines, etc) and type of fuel used (91, 93, E85, etc) have a great impact on HP numbers - and in my case, the compression ratio of the motor.

There are so many variables that change the final outcome, I'm still learning new things everyday!

The fuel is a big one, one reason I started adding it to the finished builds thread because people with much lower boost were hitting high numbers but were on e85. Helps show a better perspective into how someone reached it.

Power is power.

Good friend of mine made 510awhp in his 911. He expected a lot more, but when you pulling busses on a 600whp z06. Does that dyno even matter? I would think not lol.

11 PSI tune on a VQ37HR is power. Whether it's 500whp or 600whp. Only thing dyno is truly used for it making sure you have all the tools you need to make adjustments for clean pulls. Numbers can be so irrelevant it's all about tune and health of the engine.

Even I get caught up in the number game, but end of the day all I care about is healthy power.

tonyHTX · 04-28-2015, 11:41 AM

^ Totally agree that reliable power is best and that the dyno is a controlled environment for the tuner to work magic as opposed to WOT down the streets, I mean tracks.

I was just trying to add to jwick's response to GeauxTigers1 question as to why everyone's 'number' varies.

Fuel can definitely play a factor as well.

Fuel is everything for a high powered tune. This is why E85 is a dyno killer. I'm lucky to have 93 octane in my area, but would love a E85 pump.

Someone once told me, "if I want more power i'll do a shell 104 octane tune".

Replied, "Yea try taking the tune out of town tell me how that works out lol".

I want a tune for the average pump. Hunting down $7 gallon fuel with limited places to fuel isn't my idea of a weekend warrior. IMO, That's more like a dyno queen that drives his car to event once a month.

This is all amazing info! Wish I could quote every one of you. Much more info than I expected, freakin love this place!

Thanks everyone, added the q's to add at my project consult coming up!

I believe I did have a great advantage at getting over the "600whp" mark at the time. I did choose to upgrade to a automotive 340 fuel pump and 1000cc injectors, with the cjm return lines. I think that alone gave me a high chance in achieving my goal of 550whp. I do also have a tomei titanium single exit exhaust. I don't know how much of a difference it would have against a dual setup. On top of that when it was getting tuned, the weather had a nice chill that day. Roughly 40-50 degrees maybe less, and then I had Jon Parhams awesome secret tuning skills.

So I kinda knew I was gonna get decent numbers at the time but I really wasn't expecting to hit over 600 on 9.5 psi at all, it blew my mind. Guess I was just lucky

What fuel we're you running?

That's the same setup Charles has on his car expect for the turbo system.

Right now i'm GTM TT, 650 CC, 255 walbro.

If I do a CJM S1 Fuel return and 11 PSI tune on 93 octane. Like to think 580 whp is achievable.

Z1's dyno seems like it runs just a touch high, so that's why you're showing more power on the same boost. They're a great crew, good tuners and a good shop, but their dyno is very marketing-friendly.

Also a key point to note is the over 600 number was a fifth gear pull. The fourth gear pull, which is what most of us report, was 589 if I recall properly.

Edit - Again not knocking just trying to point out differences that could account for a high number.
