GTM Supercharged 370Z nismo with stock Exhaust & HFC- 414 RWHP 351 RWTQ 91 oct

SAM@GTM · 12-31-2010, 03:07 AM

Just want to to moment and share with you guys this beautiful strait forward project that we just finished .The results were very good and the car feels great .

Here is the list of the mods

-GTM Turn key supercharger kit STG 1
-Berk HFC
-GTM Competition oil cooler
-Stock Exhaust

Here is some pics, the dyno graph and a video of the car in action .

Sam

UPDATE --------------------------

Customer opted to run test pipes on the car so we threw a set of the GTM resonated test pipes and went back on the dyno with the same tune same gas. Here are the results with some pics .

Better HP and torque and no effect on the tune, Also no rasp and it did not sound bad art all .

How do you hit peak boost at 5500 rpm and hold peak without building more boost to 7500? Is it becuase the recirc valve opens at 8 psi? Ive never seen a centrifugal setup hit peak boost before redline, usually they keep building pressure. If theres something I dont know (probably the case), is there a way to make a larger higher flowing compressor hit peak (8psi) boost even sooner and hold it to redline? Either way, thats pretty bad ***. Are the kits workable with the LTH yet? PSI/Power drops?

it has a lot to do the VVEl and the VE of the VQ37VHR engine, same blower on a VQ35HR is doing 14 psi and over 470RWHP .

I don't think there is any issues with the 7AT, driving habits has a lot to do with it .

Just out of curiousity, what habits should 7AT guys avoid that cause these issues?

^^Agreed. 4th gear in the 7at will bring you to ~190km/hr already, there really isn't a need to juice the car with 5/6/7... Unless you're tracking, then why not get 6mt for tracking...

Im curious to know if the 'VQ Hiss' is still there with SC setups. I know on TT setups its gone, but I just figured thats because there an impeller in the way acting as an accoustic modifier/ back pressure. Does the additional airflow and temperatures get rid of the hiss, or at least lessen it? Or, prehaps just as good, can you not tell because the SC sound and recirc valve is THAT awesome?

SRT8 had to have had some mods to keep up with that car. They aren't that fast stock. Low 13's/high 12's at about 107-109 or so is about the best you will see from a stocker.

I can't wait to hear from all the little goodie-goodies about *GASP!* A streetracing vid, though, lol.

Very clean install!

G37sHKS · 12-31-2010, 06:37 AM
