Dyno numbers are loaded with so many variables it's not even funny. Weight, gear, tq curve, etc. Those 9" rears are some heavy ***** compared to a 10 bolt though. One man an lift a 10 bolt and literally throw it lol. If u can do that with a 9" you're one tough sombich.

Exactly! I'm actually starting to lean towards the tune at this point. It's been brought to my attention that some tuners tune a car in a way that it will respond differently on the street verses the dyno. Not sure how true that is, but it's worth looking into. Mine was on a mustang dyno, so there may be something in the tuning process that changes between real world racing and dyno racing. I'm calling my tuner on Monday and see what he has to say

I've never had any direct experience with a Mustang Dyno, but they are supposed to be closer to "real world" resistances. They definitely read a good bit lower than a Dyno Jet. From my understanding, its a LOT lower reading dyno which would explain a lot.

mrtstang

Right but what I'm saying is that the way the car is tuned might be responsible for the low numbers on any dyno. Mine dynoed 420 on that mustang dyno, and that was before the motor was broke in and before I added the merge pipe to my exhaust. So the dynojet numbers are significantly lower...even after all this lol

That's the weirdest thing. Seems like every time you go on a dyno it makes ~10whp less. But yet still runs just as strong as it did since day 1. lol

mrtstang

Actually it runs better than it did from the start when you think about it lol. Remember our first few races when I got the new motor and how much closer they were since the motor broke in and the merge pipe addition

Stone629

Ohhh, damn. I'm with you now! That is very strange. I mean long as its running better thats the important thing, but that is odd to say the least.

Good job! Hopefully my cars tuned Wednesday and I can have some end of the season fun.

ctgreddy

Dont you even say that madness.
