Kyle, I would like to run a larger oil cooler...at least 34 rows. Will I be able to fit that along with the intercooler?

Zguy 01-20-2010 09:17 AM

I just want to see it already....

Not sure yet RCZ! I'll look into this for you in the next couple of days. We are currently testing the kit on our G right now but it will be making the switch to the Z soon. PM the part number and description of the cooler that you're looking at running so I can get dimensions and take some measurements for you.

Yes, you read that correctly...We are driving the supercharged G37 today!!! Unfortunately the rain is coming down pretty steadily all week so we won't be able to get any numbers (outdoor dyno) and we still need to do some tuning anyways before we're ready to release final power numbers but that should be coming along soon.

Our dyno is an outdoor dyno (thankfully we back right on to the John Wayne airport runway so we don't have any noise complaints) so when the rain comes down, we can't do any dyno testing/tuning.

We should have some video's/photo's in the next day or two.

hmm, Off the top of my head the dimensions were something like 7.75"X22". Obviously it would go across the long side. It's your non race kit with an upgraded setrab core I need to buy. However if it doesn't fit then I'm going to have to do something else. Maybe you guys can come up with something :)

simota1 01-20-2010 03:34 PM

im super excited when this thing comes out.. :tup:

G37Sam 01-20-2010 04:55 PM

Being tested on a G????

WOW

RCZ 01-20-2010 05:02 PM

^ Ya...they dont care if the G blows up. Valuable info for the Z development ;)

Lol. So true.

G37Sam 01-20-2010 06:17 PM

hahahaha touché

I don't mind the bigger brother taking the beating for the smaller one ;)

travisjb 01-20-2010 07:58 PM

umm, you might just be outnumbered here, Sam ;)

Buddy Revell 01-20-2010 08:34 PM

LOL, G or Z who cares? We have the same engine, so whatever the kit's being developed on is good for everyone.:tup:

RCZ 01-20-2010 11:17 PM

^ we know..thanks for killing the fun though. You fun killing revell.

Minicobra1 01-21-2010 03:11 AM

This will give an idea on the kind of numbers we can expect, although completely different car and engine, the base HP is about the same, and I'm assuming we will be running 6-10lbs of boost.

2010 Mustang GT, stock pull was 277 hp 299 torque after the Vortech V3 install 444 hp, 400 torque with 10lbs of boost. This was a warranty install with a safe tune.

Here is a video, different car, you can hear the sound of the V3, on a mustang,
hood is up though.

G37Sam 01-21-2010 03:14 AM

A Ford Mustang has a compression ratio of around 9.8 and a bigger displacement.. hmmm

RCZ 01-21-2010 08:14 AM

Yep, throws all the calculations off. Their 9.8:1 cr is completely different than our 11:1 cr. Based on that figure, we will make more hp per pound of boost introduced into the engine.

SeeyaBud86 01-21-2010 08:28 AM

Yup. I'm going to guess around 500ish for our kit. I guess we shall see soon because they are going to give an update on the G.

RCZ 01-21-2010 08:41 AM

My guess is 460 range for the race kit.

Keep in mind the '05 and '10 Mustang GT has a 4.6 liter V8. Quite far off from the VQ37 to make comparisons. Even the old VQ35 in the 350/G35 would be a better comparison. Haha, I'm a fun killer? Perhaps, LOL.

No way, that's a 50% increase.

I wouldn't expect too much more than 400.

SeeyaBud86 01-21-2010 09:44 AM

We'll see what Stillen comes up with...I'd be fine with 400 as well...

LiquidZ 01-21-2010 09:51 AM

420-430

m4a1mustang 01-21-2010 09:59 AM

Low 400s is all I really want. That's perfect for a street car of this weight.

LUVZTTZ 01-21-2010 01:26 PM

I would be pleased with 350 lbs/ft of torque at 3k RPM.

m4a1mustang 01-21-2010 02:00 PM

At 3k rpm I think that is asking for much. The AAM TT that made 500whp/372wtq only puts down about 280lb-ft at 3,000 RPM. Peak wasn't until after 4k.

Though any little bit of extra grunt down low will help. This car has no balls until you get past 4k.

WShade 01-21-2010 02:25 PM

Yeah but a S/C will start to produce a little earlier in the RPM range than a T/T setup.

m4a1mustang 01-21-2010 02:32 PM

I'm still thinking 350 that low is going to be a bit of a stretch. I hope I'm proven wrong (I'd love to make that much torque at 3k), but I just don't see it happening.

LiquidZ 01-21-2010 06:39 PM

So Stillen, how close are we to seeing pictures?

90-120 days..











or a LOT sooner.. :bowrofl: Very soon actually..

I wouldn't use AAM's TT numbers as a bench mark yet. GTM was making much more torque with their 500whp stage 1 package

Red370 01-21-2010 11:44 PM

The anticipation for this kit is so much, that as soon as the numbers and sale price come out, i'll instantaneously wet and crap myself, and maybe have a stroke. I'd be plenty happy with 400whp for daily driven and the occasional track day.

Buddy Revell 01-22-2010 02:37 AM

My prediction: 410-420 to the wheels @ 6 psi.

:eek2: wow the anticipation is gonna kill me... lol

Z eliminator 01-22-2010 07:11 AM

I fell that at 6 LBs. boost it will make 355 to 365 RWHP. About a 100 over base line .
16.6 rwhp per 1 lb of boost on a 370 z with a 7 AT.

BLUESLATE 01-22-2010 07:23 AM

I would love to see stable 400whp with this kit. :)

I'll be glued to your blog for the next week. My girlfriend is going to hate me.

Zguy 01-22-2010 09:27 AM

Guys boost is boost no matter if its from a supercharger or a turbo.... If another kit is putting down 450-500 @ 6-9psi thats what the stillen will do... the only differences that I know of is when the boost comes on... Turbo= for the most part all at once somewhere in the rpm band... Supercharger linear gains boost with rpm

There are other factors in there that effect efficiency but for the most part I think it will put the same HP down as the TT's that are out now as long as the psi is the same, peak HP should be the same. Torque will be different though....

This is not entirely true. Superchargers require work input from the engine
to spin. This extra work required by the supercharger does consume horsepower. As an example, a turbo at 6 psi might produce 450 whp whereas a supercharger at 6 psi might produce 430 whp.

The only way a supercharger would produce the same power at the same level of boost is to run it off of a completely isolated and powered motor, thus bypassing the horsepower robbing work required by a supercharger to work.

KEVTEX 01-22-2010 11:00 AM

It also takes some horsepower to spin the turbo. There is no free lunch.

I fail to see this. The turbo requires no work from the engine to spin.

I'm just going to stop here before a supercharger vs turbo debate explodes.

Exactly, the back pressure put by the turbine on the engine "robs" horsepower too you know..
