09 ss tc
We don't know who flashed the first tune before I got the car. Church Automotive pulled the whole tune and looked at it under a microscope..lots of maps were changed. It was a custom tune very much like the one Church actually uses himself. He said it was pretty decent. However, car was detonating a bit..so he flashed over it with his custom tune..richen..etc and provide more torque down low (2000-4500RPM). After the tune, I could rip the tires in second which I couldn't do before

OH..I have absolutely NO MODS AT ALL.....ZIP! All bone stock...not a single aftermarket mod you can *SEE* anyway.

About this Dyno (Dynapack) and Dynojet
http://home.earthlink.net/~spchurch/id12.html
Registers *about* 10 HP more to the wheels than Dynojet.
This is why we recommend people use a rough percentage adjustment to estimate flywheel hp on the Dynojet versus a rough fixed adjustment on the Dynapack. In our experience, a manual transmission FWD car will lose 20-25 hp to the hubs on the Dynapack. A RWD car will lose 25-30 hp and an AWD car about 35-40 hp (the FWD case has been verified on an engine dyno). In contrast, losses on the Dynojet will be in the 12-14% range for FWD and 14-16% for RWD (opinions vary).
Let's work through a comparative example for the same car on a Dynapack and Dynojet.
Car A produces 205 hp to the hubs on the Dynapack. This would equate to between 225-230 hp at the flywheel. The same car produces 195 hp to the rollers on a Dynojet. This would equate to 222-226 hp at the flywheel. Furthermore, the difference in power matches up very well with our calculated difference due to inertial losses. And interestingly enough, we have tested just such a car on our Dynapack and a Dynojet back to back with the same results (actually 196 vs. 206 hp).

They ask for DYNO results on this thread don't they? You see OTHER dyno charts posted here...don't you? ARE THEY ASKING FOR TIME SLIPS?. Have you ragged on their asses too? BTW..take a look at my pics on the Imge link...ever done any real ROAD RACING?
Man, I wish they had an *ignore* feature here
Shaun Dyno Tuned the car, he's a great guy:

He got another 15 HP and 20 TQ:
*Note: the stock run appears to have had the bolt ons (makes sense..before &after dose same day) worth 15 HP or so. The Church dyno accounts for another 15HP, since it dynoes around 15 higher than a dynojet. That gives you a *stock* run that's +30 over stock around 245HP.

Again my car, no mods, just tune:

So, it appears all the bolt ons he used are worth around +15HP or so. Nice, but not a big deal in this case.

The nice thing about reading dyno results of a kO4 SS/TCs is....the only thing that matters is what is going on at 5252 and what happens after that.
All that low end TQ does not really mean much. It looks pretty on a graph but that is pretty much it...
HP>TQ son.
I raced my buddy in his TVS (supporting mods) and we were DEAD even from a 50 roll in 2nd gear (cold out) and from 60 in 3rd, I pulled him by half car at least (where the TQ shows)
These cars have strengths in different areas, don't get on a high horse!

You better drive my car
Anyway, How does 4.8 sec from 60-90 and 6.4 sec from 60-100 sound?
Torque Accelerates period...HP tells you how far you can take it.
I was thinking about that, but these post tend to get *lost* and burried. Just because I posted somwhere else a while back, doesn't mean that someome reading this thread was aware of that post. Even I had a problem finding it again

I'm gonna say this up front..I don't drag race the car. It's not that I haven't ever raced either (see Image Link if you want)...just road racing. I can understand why you guys would like to see times...it's not going to happen in my case. There are many reasons for this I won't get into.. one of them being>>>>I don't wanna beat up this car! I know what running race tracks can do to a car. Also, drag racing measures DRIVER SKILL. My posts are directed at CAR POTENTIAL not drivers skill.
