Jumping on a dyno jet will clear things up I guess....
Or we could do a side by side highway pull and see if the 130mph traps are there:-) which it would need closer to ~500rwh :-)

she's not makin' 500 horse, that's for damn sure......that 130 was a joke on my part. Dynojet sometime soon (and perhaps side by side highway pulls up and down 287 as well), but for now I plan on kicking back and relaxing

You got enough free tuning already. LOL If i'm doing this, it'll be for Brian and not you. :-P

Did I hear free tuning??? Bryan's wanting me to turn it up to 17psi on your next trip down to B-ham. If I'm there it'll be just to watch others because I think I lost my ***** a long time ago...lol

good meeting you too. any idea if Kan is due back to the tristate area?

Matty, my car is still a DD (for a little while longer anyway) and a frequently driven car. I really don't want to deal with the noise and smell of a midpipe or deal with the emissions ***** or overzealous state troopers.....
If I wasn't worried about the above, I would have gone with a small single turbo. BNR's+hi-flow cat = a car that looks 100% emissions compliant and should legitimately pass the sniffer test.

I won't achieve Rich's awesome numbers but I hope to make a very good amount of power while still hitting emissions and not vaporizing stock twins.....

Nice #'s with the twins

Id like to keep in touch with you, when you get some results.

In my experience, a stock (heavier) flywheel helps while launching at the strip, while the aluminum flywheel helps acceleration tremendously once underway, esp. in the lower gears.

re-read how a turbo-charger works, there really is no debate here...again, I'm not talking about the ability or inability to launch the car...that's a separate issue

92fd, I thought you confused the flywheel with a turbo compressor wheel in your post. Name calling aside, it would make a good debate. In my experience with both my non seq fd and awd dsm's, low rpm response suffered after swapping in lightweight flywheels.
you missed the point...the point is whatever you can do to help the car build rpm quickly, the faster the turbos will spool...launching the car is a separate issue (although somewhat related in terms of clutch function)
sorry for the name calling....have a good day

A lighter flywheel is a much better option, period. A heavy flywheel is like adding weight to the car- it will only make you slower. this is NOT true for a launch where you are sitting at high revs and drop the clutch, but holds true once you are accelerating, PERIOD. if i wasnt in a hurry I would post the equation for calculating the acceleration of a vehicle but you would find that masses are in the denominator, aka, they go up, acceleration goes down.
