GTM Performance Engineering: VQ37VHR Twin Supercharger System

Chuck33079

Ok, if you consider a built motor as a "supporting mod", then you're too low on costs. You can put the kit on and build the motor later, if you even need to at all. The car can easily handle 500 whp without a built motor. You may find that's enough in this car. The jury's out on the twin sc kit, but in general sc is not the correct path for an all-out big power build. Install it yourself and have someone else tune it. It'll come with a canned tune that's very good. 4.08 gears on a FI build will convert the power into tire smoke, not forward momentum. There's a 3.3 rear end if you're going for 600whp+.

i HATE to mention this in a gtm thread "sorry sam" but would it be a better idea to go with the fast intentions TT? ive never seen turbo numbers like that before, its making 450RWHP at 3k rpm!!! WTF. i thought the low rpm range was supercharger territory lol. 10psi, 550 hp, 485 tq......... thats absolutely insane. if they can get the fuel issue worked out, which i would guess just cant keep up with how quickly the car needs it, not pressure, VOLUME. you can put more pressure on a small pipe to flow more, but will still have pressure drop if the demand exceeds the delivery. increased pressure doesnt linearly equate to higher volume of gas when using a mechanical pump. the kits 9 grand..... thats cheaper than the TSC, and MAN is it clean. all you can even see from under the hood is the intakes, and to an untrained eye that would just look like you had some retarded long tube CA intakes on it. cant even see the damn intercooler unless you look straight through the front of the car, its about as hidden as the oil cooler lol.

your not the first to say that this car can hold 500+ stock..... im starting to believe it. also, random question since ive mentioned so many mods...... does anyone sell a CF driveshaft for the 370? i took the one on my old 09 off for various reasons i wont disclose..... and dear GOD its heavy. and ive even heard rumors that its actually partially carbon fiber ALREADY? really? i dont remember CF weighing a million pounds.

I won't get into the turbo manufacturer debate, because it's been beat to death in countless threads. You will find all you need to know there without hijacking a GTM thread.

500-550 is the norm on stock internals. Some have pushed 550-600 reliably.

The driveshaft is a composite (that contains some carbon fiber material), not full CF.

Ok Chii370 the Fast Intentions turbo kit does not make 450 whp @ 3.5k it makes 450 tq @ 3.5K. This is very impressive number and it is a very nice kit with some very solid numbers. I also would like to point out if your doing a build engine on a 370z you wont be doing cams our cars don't have any intake cams we have VVEL here is a link Nissan 370Z / G37 VQ37 VVEL camless intake valve system - YouTube There are only exhaust cam's from Jun that are not proven on a Boosted car I wouldn't even bother.


If you want low end TQ and power just go TT and be done with it built your motor and be done with it. I am still 3.7 with my built motor and I will be going for more power over the summer take at my charts for reference.

i agree, fully.... and i would LOVE to see the same numbers as you are, and i know what is required for the most part to do so. Thing is, putting 600 RWHP in a stock VQ will diminish the life span by a multiple of probably close to 100. i SERIOUSLY doubt even with simple day to day driving, not beating on it, that it would last much longer than 20-30k before it sends an important part of the engine into the road, through your hood, or into your dash. so a big thing for me is longevity. thats one reason why i have pretty high hopes for the TSC kit, from what ive HEARD superchargers are usually less "harmful" overall to your system in the long haul, due to typically lower boost pressures and various other things. i could be wrong, but thats what ive gathered. but i mentioned the FI kit because it was the first TT developed for the 370 so far that has seen numbers even close to that at such a low boost, and it also has the simplest plumbing setup ive seen as well. less complicated=good imo. considering the fact all of the parts will be installed by me, less is best.

also misread the dyno chart, my B. but anyway 450tq, thats even better lol.... tq=useable power converted to energy from the engine. not just magic equation numbers.
