I'm talking about Torque. It's very clearly lower initially, particularly below 2500 rpms.

dude the GTM SC makes more torque at idle than the NA Z makes horspower at redline!!!

What you are seeing is due to the dyno operator starting to record the dyno run without going wide open throttle, Here is an example of where the torque at at lower RPM . this is an in house install that we are just rapping up.

Sorry, the lines were blending together and I kept looking only at the single TQ line above the rest.
I wonder if the AF being adjusted would balance that out, it is also weird 3 of the runs are very low and then 1 is way above the rest.

great numbers...im very tempted to go the gtm route. Is the stage 1 kit carb legal or is it just the stage 0 kit?

It is the stage 1. I wanna say it is the carb route but being from philly i don't think you would need to worry

In regards to the initial numbers. The guy started it off mostly at 2500 rpms when recording so there will be inconsistancies. The highest torque I had in the low end (2500rpm) range was with the supercharger in 4th gear. 25 torque more

Makes me consider the SC route vice the TT... awesome work, GTM.

SAM@GTM · 12-13-2010, 10:38 PM

Here is the info on the new bypass valve set up, this is a fully adjustable valve with a 38mm port size vs the older version that was 24mm non adjustable .
