Dyno numbers, I expected more...
Well I took my car to the dyno and got 645whp 647wtq was really expecting more here is my mod list:
LPE 710 kit Pulley 2.35 Lingenfelter damper 14% LPE snout ported to 102mm Nick Williams 102mm LS3 ported and polished heads - Intake 387cfm Exhaust 236cfm Meth injection Short throw MGW Cam Comp cams - 227/243 @.050 .614/.624 109 CL SPEC double disc clutch Headers 2" No cats AEM wideband NT05R 345/30/19 I really was expecting at least 700whp. https://cimg1.ibsrv.net/gimg/www.cor...67c44419c3.jpg |
With those mods you should be around 750 rwhp. What's your psi?
|
Something is off.
|
I am at 17psi how can I upload the log of that run? When I try to attach it it says invalid file.
|
What kind of dyno was it?

Is the meth working right? How much timing? What fuel are you running?
|
something is deff wrong you should be well over 700whp. 17PSI seems low for that setup, unless cam make and headers specs justify that boost drops.

I notice that IAT2 numbers where on the sky, here is a comparison of the IAT2 on the dyno and on the street, same file same everything. How much power could I be loosing because of this?

it pulls MAJOR timing when the IAT2 gets that high.
I'd have to look but I think it pulls 8-9* when the IAT2 goes over 130*. |

Your car pulled 4.5* @ 6,000 rpm...
Check your intercooler fluid.....It shouldn't be 70* above ambient... Your coolant was at 207* Do the fan setup like I told you... you should be in the mid 700's |

Morphin did that info I gave you on the throttle body help ya?
Also check for belt slip....Your boost is dropping 2 lbs I would think that pulley setup would push more...I have 14% lower with 2.6 upper at 16lbs |
your belt is slipping, still not sure why power is so low on your set up. i made 752 whp in 110 degree ambient with similar set up but ported ls9 ehads. back at home with better weather with the same pulley combo im seeing 21.8 lbs (lower to sea level in washington) car got tuned in phoenix
|
The shop where I dynoed the car didnt had a BIG fan they only had 2 small ones thats why temperature got that high. I usually dont have issues with IAT2 numbers.
|
This are how my IAT2 numbers usually are:
