I am just saying that those numbers would be perfect for me. I am pretty sure the SC can reach those numbers with the stage 3 kit.

+100 hp woudl equal something like 370whp, or 420bhp, it would seem.

(bhp = brake horsepower measured at the flywheel like manufacturers)

Here is the latest dyno numbers after fixing the boost leak, we will be changing the Supercharger pulley next to get more boost out the system.

I'm liking that mid-range torque. Can't wait to see how it responds to a better exhaust system than the stock unit. Thanks for sharing, SAM.

This is the one of the advantages the Rotex supercharger, even it is a centrifugal blower it does steel maintain a good low end torque .

Assuming 8 psi is a safe boost level, long tubes and catback may produce more power than some people are figuring. At 5~psi on stock cats and exhaust those are nice gains. I would immagine a full exhaust would get close to 400 whp at 5~ psi. Looking foreward to more updates and results. Also, is it a recirc or open setup? My guess is recirc.

8 psi is a safe boost level even 9 is not a problem, we have been running our turbo system up to 10 and 11 psi without any issues. the system runs a recirc set up but it was open on this dyno run

Sam,

Is that a base model on the dyno? I am really interested in the SC kit as well, but didn't know if the stock open diff would or could handle it. I'd like to switch out the diff at some point after some solid choices come out that are verified fits.

Thanks,
Tony

i think i jus drooled a lil!!!! haha this is awesome update :D

9-11lbs plus a full 2.5 exhaust will hopefully put the Z around 450ish if not more with a pulley. If that's the case and it was that much low end torque I'd be inclined to say that a stage 1 SC> stage 1 TT.

LiquidZ 02-18-2010 07:55 AM

The torque curve looks great.

RCZ 02-18-2010 08:07 AM

344 @ 5psi in the charts.
400 @ 4.5psi in the video.

:confused:

If its flowing higher, that just means it doesnt need to spin as fast to produce the same boost. Just because a turbo is bigger, doesnt mean theres more air in 5psi than there would be with a small turbo. Less stress on the turbo yes, more psi in the psi, no.

So "obviously" that's not why. I think the numbers that were throw out there by Z eliminator are pure speculation. I dont think it made GTM look good either. Stage 3 @ 10psi only making low 400 when their actual stage 1 kit is already making 350 @ 5psi.

Wtf is going on here folks? I'm not hating here, but these things aren't making GTM look good for me. I know they are a good company, this isn't necessary or needed.

DannyGT 02-18-2010 08:35 AM

Very nice.

We all know downpipes/exhaust should give us at least 20whp so add that + the fact he is tuning for 91*...I think I could really hit my goal of 420 - 450 @8ish psi with 93* and water/meth system.

Sam, will you be tuning with 93* to work on custom maps for us guys in the eastcoast

Just guessing here but if you look at the baseline dyno and take the drivetrain loss of that times 400 you get exactly 344.

NYBladeZ 02-18-2010 08:44 AM

We're all getting tired of speculation lol, GTM its getting hard to stay patient, how about that press release to satisfy the mob already
