at a bolt-on crossroads...

SPOHN · 11-13-2012, 12:00 PM

I just ordered the Momentum 350z headers and TP's from Z1 yesterday. Can't wait to get them on and tuned. Good thing the headers reduce weight also. A good bit (16lbs). But yes weight savings is a big win.

Or shoot nitrous at it from time to time.

spohn, i'm waiting to see the before and after dyno with those headers onyour car before i make any decisions on the headers. are u doing the vvel tune as well?

Might I also suggest the Mustang 5.0

i wouldnt mind seeing a company take some chances

i.e: new manifolds, individual throttle bodies, active exhaust, larger tb's, polishing throttle bodies (no i'm not paying mines $3700 to do 3 hours worth of machining), roots style blowers, ANOTHER TUNING SOLUTION, different cam options, more companies offering head work, etc, etc...

i just feel like the aftermarket has been somewhat asleep at the wheel on the performance for the vq37

Many of those items you listed you can have done at a good shop, if they can do it for X engine they can do it for the VQ37, just have to work with them on what you want. Like, larger TB, polishing TB, cams, etc. ITB and roots blower can be done by good shops as one offs but will be more expensive.
Tuning, I think Uprev is doing a great job, we now have VVEL starting to come out with early testing and seeing good results. Tuning is something you do not want to rush, and with the limit size of the Z ownership things will be a little slower compared to other cars.

Not sure of all the tuning that has to take place or how much the VVEL can be played with. But what ever it takes I'm game. There has to be something done with the valves to help such as overlap. But that's the secrets of the tuners.

Completely agree, because when it gets hard, it's easier to go boost. I think there is easy hp sitting on the table that requires some engineering investment. There are only one set of cams available, and most parts available with engineering behind them came from Japan that mere mortals can't afford or makes no sense to dump that much money into it. Maybe if we had GTR money, but then we'd have a GTR.

The only thing superior about a Mustang is the 5.0's power (and the diff). You forgot about the brakes (pads and fluid kills any argument), handling, Forged rims, lighter weight, better dynamics (axis of rotation is actually the middle of the car). The 5.0 card is played out. We would have bought one if we wanted it.

I'll geting PPE headers installed soon -- dynos to come, but I expect them to make lots of power.

A good setof LTH's is the way to go -- stay tuned for clear before and after data on PPE.

5.0 has better brakes and is only 300lbs heavier. Sway bars can fix weight distribution.

Not going down this rabbit hole, but no and no.

Jordo, Looking forward to your results. I gained 30whp with the headers and my exhaust setup, another member gained 35whp on a stock motor and tuning.

The best bet cost per performance wise is going to be those gears, all the bolt on's you listed OP will feel like nothing compared to a set of 4.08's. You will be kicking yourself in the rear for not having done it first. You will lose some MPG but the acceleration difference is huge. You won't gain any more power, but you will accelerate much faster, that will tide you over till the gains for cams or anything else will become available to public knowledge.

edub370 · 11-13-2012, 02:30 PM

anyone documented the 0-60 or 1/4 mile change on stock gears vs. 4.08's?

SPOHN · 11-13-2012, 03:39 PM

I so regret not doing the 4.08 when I did my LSD.

jcosta79 · 11-13-2012, 04:25 PM

I've been down this road before. If you got the itch really bad, maybe you should consider selling the Z and starting over with a different car that has more power potential.

Yes you can squeeze a few more ponies without going FI, but if you're not going to go down that road and you really want more power, the Z platform is not going to get you there.

Think about what you really want to accomplish. If you don't want to change to another platform, your only other realistic option for a lot more power is to go FI.

Best wishes with whatever you choose!

DANG. reality is a bitch.....

i got to drive a c63 the other day that got me jonesin' for some more power
