Full exhaust with HF cats and x-pipe
2.73 degree upper pulley

Cold-air intake

Blower, MAF, are stock.

Port the stock blower and upgrade the MAF....you would see close to 650+ and close to the same TQ......get a bigger blower and the sky would be the limit...

No way in hell. not even at the crank. . . as per your current mods id say 460whp . . . .

I agree on the nowhere close to 650 with a stock blower. You are going to want to either go ported stocker and spray or twinscrew to get past 600 rwhp mark

+1 maybe a bit lower, just depends on the tune.

1StockGT · September 26th, 2009, 03:36 PM

It'll definitely take a TS or turbo to hit 600+ rwhp. I guess you could get a ported eaton and lots of nawzz.

FX4DTUF · September 26th, 2009, 03:44 PM

ive seen non ported eaton cobras with full bolt ons make 500hp im meen look at Almo's car.

Almos car was a freak. It also didn't make 650+.

The reason he went so quick was lots of weight reduction and good suspension setup. It wasn't all about power.

FX4DTUF · September 26th, 2009, 03:49 PM

but it did reach 500hp

BoostFiend · September 26th, 2009, 03:52 PM

True, but there are also full bolt on, non-ported cars making 440whp.

I think he will make a tad bit more with his stroked and built motor, but no where close to 650 that Yellow02Gtauto was claiming.

FX4DTUF · September 26th, 2009, 03:54 PM

yeah def but im thinking if he gets a good tune and a upper and lower pulley set up and a good Maf he will reach 500+

Smoothgrandmama · September 26th, 2009, 08:56 PM

on a 2.73 pulley without a lower i dont think he will crack 500. . . . he night but its not likely. ya its a stroker and ya he put some gt super car cams in. . . but termis dont get alot from a cam swap. so between 460-480.

BoostFiend · September 26th, 2009, 10:17 PM

If he ports the blowr it will be 500 easy. I agree that it will be between 460 and 480.

Mustang RacR94 · September 27th, 2009, 12:47 PM

my friends made 460 with upper pulley, bassani heads O/R x and catback, JLT intake.

so my estimate would be very high 400's to very low 500s
