GT Motorsports: 370Z Supercharger system development

Buddy Revell

Interesting point. I welcome a technical conversation about the positives and negatives of each kit before I put down such a large chunk of money on either kit. Thanks, Sam.

SAM@GTM

Yes, that is the way it should be and it is for everyone best interest so you guys can make an informed decision.

i guess the reputation precedes the product........ *^^* as such, the PERCEIVED quality of the brand name and the product dictates the market value....

i, for one, cannot speak from my personal experience, but from gathering info from forums, ppl dont seem to have any problem w GTM...........

Travis = much more polite than I.

Sam do you think the larger manifold that comes with the Stillen kit will hinder the VVEL's operation and performance in general? Back in the previous gen Z's, those upgrading to FI manifolds needed cams to get that extra air into the engines efficiently I believe

Let me take my GTM hat off for a minute.

I as a Tuner have some serious concerns about what stillen did with their manifold disghn and yes it will hinder the performance and drivability of the car in general.

issue # 1

The mass air flow sensors contains the air temp sensors so by placing the sensors on the hot side of the blower and then cooling the air inside the manifold the ecu is not getting the right info and will cause a lot counter actions from the ecu due to the extreme air inlet temp it seeing, if you ever touch the hot side on a vortck blower you will literally burn you hand . these ecu are very advanced and this disghn will cause a lot of issue .

issue # 2

The factory ecu uses two different inputs form the mass air flow sensors to control the fuel trim on bank one and bank two and literally there is separate maps for each bank when it comes to controlling the fuel, these fuel maps are not the same meaning the engineers at nissan knew that the amount of air entering each bank will be different and therefor every bank uses it own majoring devise (mass air flow sensor on each bank)to control the air fuel ratio.
Now when having both sensors on the same tube reading the same voltage to the ecu...…i think the answer is clear.

Maybe stillen knows more about the VQ37VHR then Nissan them self .

It is clear to me that stillen rearranged the car around their supercharge kit without taking all the factors in.

can't wait to hear some responses from Stillen on all of this... I hope they have an answer... I don't even freakin know half of the things you guys have discussed lol, but doesn't sound great

Doesn't surprise me that one vendor would talk down about another vendor's product based off a picture. Happens every day. Worth about 1 shiny penny to me. Products will reveal themselves all in good time. If product A is ****, people will not buy product A (all things being equal such as price)...

Well, if I ever learned anything in management, it's that the consumer will base his or her decision based on two of the following three qualities:

Cost
Performance
Quality

You can't have all three!

The flaw in that famous line of thinking is the lack of timeline in the equation. On a long enough timeline, all 3 can usually be achieved through technological advancement.

gleonard

the problem is that the quote is actually price, speed(of delivery), quality... choose any two.

performance can be lumped in with quality.

my 2 cents

You can have a "quality" product that does not perform as well as another product of inferior quality.

Sure you can, if you have the money!

No, because if you have the money cost is not a factor!

I don't know if that is necessarily the case. Sam commented on things only after i brought them up and others questioned them. Its not like he came on here posting bad things about the Stillen kit, only answering questions. I probably shouldn't have mentioned them, but i honestly was disappointed in the Stillen set up. With everything they talked about in the earlier thread, i was anxious to see there design, and had good visions of the kit in my head. First of the Lysholm unit, and then when they said V3, (while i'm not a fan of the Vortech units) i was still hopefull for some VERY clean piping running right out of the charger directly into TB's (positioned on the drivers side) about 6 inches away. Then i saw the pics. Not at all what i expected, and it raised more than a couple of questions both in function and form.

I was planning on keeping these to myself, but had a momentary lapse in judgment earlier and posted my true thoughts.
