In shock...474hp at the dyno
#46
Thats what I would do... just go to the track and not even look for ET.. just the MPH...

If your car is running lean you should be seeing normally more torque on the dyno not less, it was already mentioned above I believe.
The stock ECU will adjust for the intake and exhaust mods, you should not be running lean.
All of the above indicates to me that your tuner was not having a good day, or you maybe misunderstood what he told you.
In any case his dyno needs serious calibration/maintenance.
Don't get carried away by these anomalies, I would do my due diligence before using this dyno for further assessment of mods, it will obvoiusly mislead you.

Very very true, everybody knows that with "stock" 16's you can only get so much Hp/TQ regardless of ECU, exhaust, etc...You cannot acheive mid 500's on stock 16's especially with stock ECU programming, not even close. Obviously somebody has not calibrated the Dyno or is full of it. Not to bash anybody but who has ever seen more than say 500-510hp with stock ECU and turbos at the flywheel???? Anyone???? I think not. Maybe try and get car dyno'd somewhere else first simply for piece of mind.

SAE factors can be manipulated. The dyno here is seal level, so it hardly needs any correction, yet the operator has put in a 1.06 correction factor. Thus a 350rwhp car will make almost 400rwhp on that dyno.

I talked to the guys who own the dynojet. First all dynojets do the "same thing"...so minimal variation between machines...nothing is wrong with the calibration. The correction factor is software controlled based on measures atmospheric pressure, temperature...and altitude (5300ft). Now a case could be made that since I am running turbos there should be no correction, so I am getting the uncorrected sheets sent to me. However, they said all turbo and supercharger folks use the correction factor!

The newer dynojets have the built in stuff that detect measurements, of which can still be altered.
That dyno's altitude is 5300ft? Probably has a massive correction factor.

I would not think an NA engine altitude correction factor would be appropriate for a forced induction system...as suggested by another, this would appear to be the source of the inflated reading.

Wross,
Sorry so many are busting your ***** but I think they are right. You are looking at it correctly that you just want to see what improvement the mods add. It seems unscientific but what markski said about the trap speeds and the hp is pretty darn realistic. I am interested in the after mods run. Good luck with the mods and don;t let the newfound power cause you to loose your liscense.

Thanks Silver...they're not busting my *****...they are just trying to help me explain the unrealistic numbers (I know this)...hence the title of my post...In Shock. I think it comes down to the correction (inflation) factor. So let me repeat I don't care...just trying to compare before and after...probably never get trap speeds as that is not my thing...also don't care...also hope I don't lose my license(already been caught +40 over speed limit)...but the new found power really won't change the possibility (probability) of that...the thing was already fast!!!! Love those TT's!
did I say I don't care?
did I say I don't care?

I have an Idea.. why dont u go to another duno somewhere else... that should explain alot

Wross,
You have this planned very well but you obviously have a hokey
dyno number. try somewhere else as a comparison or use an AX-22
before mods (I would offer mine). Then do your after.
