Now for the catch my buddies mustang  was previously dynoyd at 578hp and the new numbers were 572hp so he was happy too and took top honors with me right below him. |
You cant really go by the numbers that Johns mustang put down with the previous owner. Dynos can be skewed to favor the tuner if you catch my drift. So that comparison would be much better if he had run it on a know accurate dyno himself.
I was there when it put down 430 on race relateds dyno. We made sure that the correction factor was set up right and they gave SAE numbers.
The dyno at nissan's settings are all screwed up. Get it to Roys and back up the numbers that it put down at Race Related

To me, that looks like numbers from a bigger cubed motor than a 346cid with the TQ being so close to the RWHP. Ive seen 346's with (ETPs, TFS & AFRs) make 430TQ but their RWHP was always 470-500, I dont know. |
They are definately off

BTW, I bet that you either have ported heads or the

engine with unported heads make that much power
without nitrous or forced induction. |
They are definately box stock with no portwork. I was there when the head/cam swap was done.

Heads are not ported to my knoledge or the previous owners.. it is stock cubed and no power adders!!!

Definately stock bottom end w/ 243's

Who cares about dyno numbers as long as it rides out. |
Exactly what I said the day of the event!

Definately. But not 450 without some portwork, bigger intake,etc

Break in the trans, dyno at roys, go to the track (while keeping fingers crossed and butthole clenched!).
