Im new at this, so opinions would really help. I will post up the dyno as soon as i get to a scanner
Here is the Set Up
Fully Built Motor w/ HKS VPRO & AAM's Fuel Set up
Power Enterprise TT

Here are the numbers
At 15 PSI
Max Power : 493HP between 6000-6500 RPM
Max Torque : 495TQ @ 4500 RPM

Correction Factor : UNCORRECTED, Smoothing : 5
Run Type : RO
Run Conditions: 61.23 F, 29.60 in-Hg Humidity: 8% UNCORRECTED: 1.0

Aren't these numbers pretty low for a dynojet? especially at 15psi?

Im impressed by the torque, but kinda disappointed that it didn't make more HP...
BTW these were on street tires and stock rims

Please, your opinons and suggestions

 

does seem abit low. you should be around 13ish psi with those numbers.

 

Eagle's car made 443@11.5psi on PE Turbo's... so maybe those numbers arn't so bad.. and it all depends on how they tuned it... might just be the kit

 

well, i did ask for a conservative tune, what kind of numbers do you think i will make on a mustang dyno?

 

I'd think the psi number would partly matter on the size of the exhaust

 

Here is the first tune on the JWT 700 BB twin turbos, but at 2psi higher:


Then we tuned it down for a race worthy lower boost level:



These are modified Garretts, T-28 units. You cannot necessarily compare outputs because the turbos are different than the PE turbos. A set of Greddys at these boost levels would be throwing out much more power, because they are bigger and pushing more air and fuel.

What really matters is the dyno plot and the useable range and power that the turbos are giving to you. At around 500rwhp and torque you are pushing a very nifty amount of power, about as much as you can hope to hook up and use. Let us see the plot. I would not be too concerned or expressive of potential disappointment just yet. The PE are good units. But a quart container can only hold a quart....not a gallon.

 

my apologies i was talking about eagletanggreen

thanks for all the inputs, i will post this either from a scanner or take a photo of the dyno paper tommorrow.

as far as 60 F, and 7-8% humidity.. these are favorable conditions for an uncorrected dyno right?

thanks

 

oh by the way, as far as comparing my car to dyno's above, i had my tuned at a conservative level, and my air fuel ratio never goes above or near that straight red line.. so as far as being safe. i hope that these lower numbers in comparison to EAGLE's would be much more safer for me.

 

Wow thats low....... Ida been really pissed after all that $$ spent...

 

actually, let me verify this with aam tomorrow, my car was tuned at a low boost (13psi) and a high boost (15psi) setting. .. im not sure if this dyno is the low boost or high boost


(stupid me, i got too exited test driving my car)

 

AAM's dyno is uncorrected and seems to run a bit on the conservative side for numbers. Would you be any happier if the dyno chart had said 550 whp? It doesn't make your car any faster.

Take it to the track, run it on the highway, just go drive the car. If you can't help but smile every time you get on it, don't sweat it. Who are you trying to make happy, us or you?

 

hehe.. +1 ^ ..

you do have a really good point.... i should get my car back after i get back from cali.. i just left it there to give me time to pay the rest ..

but, it sounds amazing.. especially the hks bov...

your right...im just curious if i could do better..

 

Have you had baseline dynos done at any other shops? Or is this your first dyno pull ever on the car? The big problem is every dyno reads differently. AAM's dyno is going to read different every month because its uncorrected. I think I put down 233 rwhp there in 98 degree weather w/ 90% humidity which was the same as my baseline dyno at Car V2. Without a basis of comparison, other cars running the dyno on the same day, baseline dyno on the same dyno before and after the build, etc... the numbers end up being kind of meaningless.

I wouldn't sweat dyno numbers. Focus on your A/F and your torque curve. Those are the 2 big keys. Besides, there's nothing worse than getting big numbers on a real friendly dyno to be punked out in a race by somebody who is claiming a lot less power than you.

 

another good point.. actually this was my very first dyno ever, i never even dyno'ed it when i had the turbonetics kit.

i guess i always would rather have a conservative and safe tune rather than high numbers..

 

Absolutely correct. You want a steady air fuel ratio across the band, a long "flat" curve of power and torque rather than a jagged climb and descent from a pronounced "peak", and not too much of a spread or gap between the torque and hp curves, as well as a tight matching of the curves for two or three pulls.

Then you have your motor set up, and you move to improving the braking and suspension. Once you have that sorted out, you have the biggest mod to work on, and that is yourself as a driver. Most important "go fast" cog in the assembly, and usually the weakest for most of us.

 

Wrong. They have a Dynojet, the numbers can be uncorrected (actual), SAE, STD or a few other less known DJ corrections. Id think with the temp at 61 when the pull was done the #'s would be close to SAE or STD, applying either one of those corrections could add or subtract a few hp.

OP-How much timing are you running at redline? Id like to see the graph. I remember you had posted you wanted higher hp goals, but dont let anybody get you down 500/500 are great numbers, and Im sure that car is a blast to drive. People get caught up in these online Dyno # competitions, screw all that and enjoy your car, have fun with it. Im sure with your set-up and those #'s you have a long life of good power ahead of you. Congrats on getting it up and running.

edit-OP--->ask Mike to check the file and apply an SAE or STD correction to your dyno above and post those #'s, its better to compare STD vs STD or SAE vs SAE online from DJ's than it is to compare uncorrected to corrected numbers.

 

Sorry about the crappy camera pic, i will scan this later at work

Opinions?

 

The HP curve looks nice, Id like to see the car revved to its rev limiter though, its cut off way early. 400ft/lbs @ 3300rpm's is nice.

 

somewhat off topic but don't the PE kits have smaller Turbos than the Greddy or APS?
