Maybe ported/polished heads? Titanium engine bits? (probably stuff that doesn't even exist yet for the VQ37 for all I know). I just don't see the OP getting his wish.

At what point would the clutch need to be changed to handle the increase in hp/tq?

Thanks!

Well, the 5.0 is not going to be putting them into the 11s.
The Mustang is rated just over 400 and we have not gotten official rear wheel numbers to see the power loss, add in the weight, and other things and it is still close. Heck the new Camaro SS has a good 100hp over us and it barely wins in a straight line.

Remember guys, just because we cannot get 400rwhp does not mean we are slower, after you get going on power look into weight savings a bit maybe and better suspension or braking. Just because it does not add to your power band does not mean it is bad.

I agree, yes the new Mustang will be fast but I can't see it running faster than mid to low 13's and that's magazine numbers. Real world drivers will not run those times, a Z with the mods I've named thus far shouldn't have a problem with the new mustang, if the Mustang weighs around 3600lbs which would be pretty light for an American car it would give the Z's with sports packages around a 300lb advantage, and that is a lot.

kevin.z · 03-14-2010, 12:57 PM

I just want my Z to be able to stack against M3! 350whp should be able to beat a stock M3

StealthZ · 03-14-2010, 01:04 PM

crack the vvel, polished and ported heads, all bolt ons possible, I would imagine it may put you in that range, always try new pistons etc... but then you get in the price range of the S/C system... I think it would be sick to see a full on N/A build with a goal of over 375WHP

a little less than 350whp would be more than enough, e92 M3's have put on considerable weight, they are no longer the raw GT cars they used to be.

KillerBee370 · 03-15-2010, 12:04 AM

Nope.

From my dyno today...

It just ain't gonna happen without FI.

Is that flywheel or RWHP?

kevin.z · 03-15-2010, 02:23 AM

rwhp because i think killerbee has all the bolt on's including jwt clutch and flywheel.

NYBladeZ · 03-15-2010, 10:25 AM

LTH's are probably good for another 4-7whp, but regardless those are still really nice numbers. I believe those are the highest documented N/A numbers.

RCZ · 03-15-2010, 10:39 AM

It completely depends on the dyno, I could go on a dynapak right now and make 350rwhp easy. They read so high. Dynojets read a bit high too, I'm probably at like 330whp on a dynojet. The dyno I used (Mustangdyne) reads more accurately when you consider the whp/weight vs. performance figures (performance seems to match what you would expect 310whp/3300lbs to do). If I were to dyno on a dynodynamics I would probably put down 300 or less because those read low.

So you have to know which dyno you are talking about. This is my rule of thumb:

Dynapak: +15%
Dynojet: +10%
Mustang: 0 (base)
Land&Sea: 0
DynoDynamics: -5%

I don't know the numbers, but I have a hard time believing that would beat the BMW V-8

Those are dyno graphs, rear wheel.

Don't ask me how I know, but my car is as fast if not a little quicker than an e92 M3.
