So I put the car on the Dyno this morning. I am no expert, nor am I going to come on here and have any type of ego. With that said I have some questions for you all, or should I say I want opinions and feedback.

Heres the deal- on the best pull the car made 655 hp at 6,350 and it made 565 tq at 5,500.

The mods I have-
AWE Cat back exhaust
Mamo Motorsports TB
Roto Fab CAI

Are these numbers at all realistic? Or was I on a overly happy dyno? Now the guy said these numbers reflect the conditions (55 degrees ambient temp)
He said the SAE was more like 630 hp.

Would love to hear what you all have to say.

Thanks Chad

Those numbers seem high for sure. 6sp cars will dyno higher due to less drivetrain loss but man, that hp number seems high to me from what I have seen. Do you know what gear they did the pull in? Was it a Dynojet? Surely not a Mustang Dyno they are notoriously more stingy. That is NO tune correct?

Unless there's a tune, flex fuel running E85, and/or a O/D pulley on the S/C I don't see those numbers being realistic at all. Not trying to rain on your parade but, from what I've seen you'd need all three I mentioned plus what you've done to get in the 650 range. Even that SAE conversion seems waaay high.

For what you've done I would expect to see 585-590, max.

But hey, I wasn't there and it might be you have a unicorn.

I have basically the same mods (albeit from different vendors) and I dynoed at 627 WHP, and my car is a fairly healthy example. Having another 28 HP on top of that without one of the following:

-E85
-Tune
-Ported Supercharger
-Pulley

Would be basically impossible, even on the strongest running of cars. I'd check another shop, or have home boy adjust his correction factor. Your SAE number is much more in-line. Check my thread for my results:

Those numbers seem excessively high, I would expect to see in the 570-585 range and the TQ should be in the same ballpark, but you have a wide disparity between RWHP and RWTQ. That is a very strange DYNO run.

[RDBill]

The numbers seem off if for no other reason the HP and TQ of these cars are relatively similar even after modifications and yours are not all that close. For example my car bone stock (A10) made 550HP, 560TQ on a 90+ temp day. After some modifications it made 730HP, 755TQ. You have a spread of 90 which doesn't make sense to me but also not being an expert I don't know what would cause that.

Your only mods were: cat back exhaust, ported 87 tb, and a CAI? No tuning? Dyno says 630 rwhp SAE? My opinion is that dyno is very optimistic. Too bad you don't have a baseline, because then you'd know what really matters, which is the gain from the mods.

Mine with from a 574 baseline to 627 with those same mods, on the same dyno.

That’s impressive, wouldn’t have thought the gain from those simple mods would be +53hp.

I wouldn't have either, but the results are what they are, I was happy! Both cool days, both same dyno, same dyno operator, etc etc.

No joke, I'd be over-the-moon with that. So far all I've done is a drop-in green filter, TM TB, and Borla X-pipe. I've never dyno'd mine, so who knows what I'm getting.

Always going to be variations among dyno runs. But your HP gain from minimal untuned mods, the peak HP (more than me with the mods/tune below) and the gross disparity in torque tells me something is way off. Heck, your peak torque with those mods is at a completely unrealistic rpm. I don’t need to see the dyno sheet to know they are no where near accurate. No worries though, if it runs and sounds good, that is all that counts!

I agree with you about the torque number, and how it’s at 5,500. Something doesn’t seem right to me either. Which is another reason why I’m on here asking.

Dyno numbers are fun to play with I guess. If the car moves out.....it will show in the mph at the track. FACT
