370ish whp, do you think it can be done?

kdoske · 03-13-2010, 09:32 PM

I don't have them so I obviously can't answer from experience. Pully swaps are really more for quicker engine response rather then higher HP. Also you don't need to rent a pully. You can buy them for 7 bucks.

still can't justify getting them, maybe after i finish the exhaust, cf work, and clutch/fly I'll revisit the idea.

I hit 'yes,' before I realized he's talking wheel hp. I think you could do 370 hp at the flywheel, n/a, but it would take a lot of work and money. But not wheel hp. So I guess my answer is 'no.'

yeah, easily done at the flywheel, no way at the rear wheels without massive infusions of cash.

I started at 250whp and im now at 310whp. Thats 60whp over, even if we went 1 to 1 hp to whp, starting from 330 I'd be at 390. So yeah easily possible to do 370 bhp.

IMWEZL · 03-14-2010, 04:05 AM

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

Thanks!

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.

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

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.

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

StealthZ · 03-14-2010, 12:04 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

kevin.z · 03-15-2010, 01:23 AM

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

NYBladeZ · 03-15-2010, 09:25 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.

Correct! The only thing I don't have is the LTH but I believe those actually LOSE power according to some previous testing.

I want to see it. True the dynapack reads higher because you're not rotating the unsprung weight of the rear wheels however I don't think you'll hit 350 easy. I put down 315 on a dyno dynamics which is yet another "heartbreak" dyno according to some.

The good think about the dynapack is that it gives you an accurate rwhp... as in, the power that is hitting the rear wheels. Not power to the street.

Correct again.

I'm not going to get into an argument here but I've seen dynapacks read as much whp as the car was supposed to have bhp, they are all over the place and usually read too high to give any indication of real power. I'm not sure why you think that's a good thing, I guess if you wanted to know an inflated number of what the car is putting down without wheels and tires on, only drivetrain loss, then that would be good.They are just notorious ego boosters in every car community I've ever been on.

315 on a dyno dynamics is great though, that you can definitely be proud of and is a much better approximation of the power your car is making.

Moving on.
