Nice comparison. Peak numbers aside, area under the torque curves are similar.

Could the spoolup difference be the Xedes rpm mappable boost control?
What boost control did the RNR/2.4 have.

Cool, when I first saw your post, I didn't realize you were the guy who tuned it..... I was thinking you were a retarded newbie

I believe the better spool of the AMS set up is due to it using the .63 turbine housing. The RnR car has a larger one, so even its additional displacement (~.12)can't make up for it. Both cars were running very low boost: just over 19psi.

That is Jimmy's. How ya' doing Ryan? The point of the post was to show two great cars making really nice numbers on VERY low boost. You can see that the AMS spools a little better, but the RnR has nice little torque hump that is impressive. Both cars were at or around 19 psi. Rumor has it that the RnR car makes 440whp on this dyno when tuned more aggressively on 91.

Ya, Jimmy has the .82 AR GT series 4 bolt so that might be part of the reason for a little more lag. Both cars are pretty impressive in my opinion.

The RnR car ended up making as high as 440 on pump but settled closer to 420 at 22psi. We wiil look for the graphs later today.
