this run was on motor converter unlocked

this run was on motor, converter locked 21* timing

same run with 26* timing

this run is with the 250 shot. tires spun on the dyno and didn't hook until almost 5500 rpms

here's the same run using mph, so you can get a little better view of the run

HOLY SH*T!!! 662/589? WOW! What a friggin monster, nice numbers

**mrr23** · 11-08-2007, 07:43 PM

the 589 rwtq is at 5700 rpms. imagine if the tires hadn't spun what the number would be. seeing as the na numbers matched, that would assume to be 663 rwtq as well.

402 RWHP ----- 379 RWTQ
506 RWHP ----- 481 RWTQ
Those are Hastings #'s before and after N20.
So that definitely goes along with what you're saying. Pretty consistent. Both of your previous nitrous numbers on both cars are right on with each other, so yea, you're def putting down more tq than that. Damn, guess you're the torque monster
