Why are these S/C kits coming in under the advertised numbers?

GTM Performance Engineering 370Z SUPERCHARGER KIT PRESS RELEASE

ummmm... what are you talking about?

Jamaica

Does he have any Z in house installs on this kit?

DarkZide

So stage 0 "up to 450" makes 42X and their stage 1 "up to 500" makes 452 and you think thats correct numbers?

Should be stage zero ~425 and stage 1 ~450

sylenze

key words are "up to"... he did not say at 8 psi stage 0 will be at 450... he is trying to differentiate the capabilities of the different trims of the Rotrex compressor... perhaps actually reading and understanding the whole press release would help ... also check out the dyno sheets at the end of the press release... maybe those pictures will be easier to comprehend..

DarkZide

I did look at the press release. Thanks for being a jackass an insulting me rather than reading my post.

Stage 1 on a exhaust-modded 370z should be closer to 475 or so if the advertised result is "up to 500". You cant have an "up to 450" and then the next stage up only makes 452. Thats dumb.

I guess factory 370z's come with "up to" 1500hp. key word "up to"

Zsteve

I would say the "up to" parts depends on different mods, PSI, altitude of where car will be , temp etc. Its not an exact science so I can live with up to. The actual numbers seem to be about par for SC cars out there that are carb legal.

I could live with "up to", don't get me wrong on that. They just seem way low for the top of the "up tos", thats all.

I figured one could get 430-440 out of the 0 kit with a decent exhaust setup and a worthwhile tune. and at least 470ish out of the stage 1. Not 425 and 452.

What a retarded argument...

If it's anything like what Stillen advertises, it is estimated BHP. Which is useful for people paper racing based upon the stock 332 BHP figure. It's actually safer to state the estimated crank horsepower output of a kit since dyno and atmospheric conditions vary so widely. 500 BHP can very well end up just over 400 WHP on a low-reading Mustang dyno.

The rating of the horsepower output of our force induction systems whether a twin turbo or the supercharger set up is in BHP (brake horsepower ) just like how Nissan rates the car on their web site, the 370z VQ3VHR engine is rated @ 333 HP . so i think your are looking at the press release and seeing up to 500 HP and then comparing it to the dyno graph we have posted, the only problem with that is you are comparing WHP ( wheel horse power) to BHP (brake horsepower ) and i think that is what's causing your confusion .

So our stage one kit is rated up to 500 hp which translate to about 415 WHP depending on the car and the dyno and the same goes for a stock 370Z with 333 HP from the factory that will also dyno @ 275 whp

Hope this help .

Oh, thanks Sam.

Didn't realize the ad numbers were BHP.

sylenze

so Sam... are you gonna have a Z with this kit for the fontana meet?

SAM@GTM

No problem, This is the only way to rate systems like these. This is due to so many variables in conditions and set ups .

Sam

SAM@GTM

Planing on bring four cars, 2 with the twin turbo set up and 2 with the Supercharger kits.

Are they going to be the 370's superchargered or the the G37?
