Darth, I went to Henneseys' site and couldn't find anything related to Z's...only Vipers and such. Any idea if they have Z upgrades published anywhere? Thanks.

Darth: Great numbers! Have you removed both the pre-cats (necessary for the long-tubes) and the regular cats?

Other that LARGE, can you describe how the power curve feels on the car compared to stock. We know it is much stronger, but when and where and how do you feel the power?

Thanks!

Darth,
Great numbers!! Do you think your stock clutch will hold up with the amount of power you are putting out?

That is an issue that we are looking at right now, actually.
We'll see.

We added the Underdrive Pulley & the computer has had a little more time to cycle, although we are still running the Stock programming. We should have that worked out in the next couple weeks.
Here are the new dyno results done on Sat.

Conditions were:

Temp=53.3 Deg F
Vapor Pressure= 0.2 in. Hg
Barom.=30.66 in. Hg
Corr. Factor = 0.93 SAE



Actual #'s=455.9 RWHP & 429.1 RWTQ

CORRECTED= 425.3 RWHP & 400.3 RWTQ

I will keep you posted again after we get the Comp reprogrammed, we hope to pick up some more at that time.
