GT Motorsports: 370Z Supercharger system development

DannyGT · 02-13-2010, 11:47 AM

So, ya, mmmm 8psi @ 93oct with the snow performance meth kit I have here should = ~450whp.

Zsteve · 02-13-2010, 12:44 PM

so 2 psi got 35 hp, will 4 psi get 70 and 6 psi 105?

Z eliminator · 02-13-2010, 03:43 PM

I got the same numbers that you did 105 and thats standard horse power, not SAE!
My base line 265 + 105 = 370 RWHP. Now with some tuning there should be
more power. 11 to 1 compression with 6 lbs = shorter engine life. 8 lbs = 400 rwhp, I would say the engine is at risk. (my stillen stage 4 , 8lbs, killed my 3.5 in my 350.)

Found this on the GTM site

The Stage 3 Kit continues where the Stage 2 Kit leaves off. Included with Stage 3 is the GTM Flash, as well as the complete GTM spec 2.5" cat back,Designed for N/A/Supercharged use but suitable for mild turbo charger applications. Features full stainless steel construction with a high polished finish.And Our GTM Supercharger Turn key kit .
it has a list price for the supercharger of $5390 may not be the same kit though

The VQ35DE has weaker internals.

just speculations..........

on the same note, GTM increased the price for TT on 370z by about 33% when compared to 350z..........

perhaps they will raise by as much in the SC kit for 370z as well............

since it would cost about $15k to get 500 RWHP TT kit, it would not be any cheaper than $10k to get RWHP in that range....

of course, if they were to offer it at the range of SC for 350z, ppl will presumably jump at it and go "nuts." ................... i know i will.........

In what way did it kill the 3.5? Hope it wont do that on the 3.7.

Im with the lower the price and more will buy thing. At $9-10K, no way. At $5-6K yes. Maybe they need to do some R&R on here at what price it will sell to the most people.

Z eliminator · 02-14-2010, 01:42 PM

I broke something in #2 cylinder, lost 40 lb compression. currently installing a 4.2 gtm with wolf 850 tt.\ in the 350.
If the price is to high i will leave the 370 N/A

I agree with you there.......I know GTM is working hard with the SC system but I lost some intrest in the product. If they worked faster I would have been an impulse buyer.....ahh boy

Looks like they just bumped the price to $7390 on the website. That wouldn't be too bad if that was installed price, don't need the CBE.

How many miles b4 the engine died? and what type of miles, hard launches -1/4 mile runs, WOT everyday? that type of driving will shorten the life of an engine too

I understand that anytime you add F.I. to a motor, it tends to shorten the lifespan, but driving style will have a big impact too. Was your system running anti-knock sensors?

I think anything over 7k is going to kill their sales... you can TT for a little more... The supercharger was supposed to be the cheapER FI solution.... Im sure to most a 1-2k difference isnt cheaper....

Read the page people. $7390 includes the stage 2. Minus the stage 2 option is $5390.

Well that depends on what's included.. that price of 7300 had an exhaust included in it which the TT kits don't ever include so thats an extra 1.5k ontop of the TT kit cost.

TT kits cost 15K on average so it seems. I don't think this kit will cost anywhere near TT costs even with the upgraded clutch and exhaust options.
