i have the same pulleys minus the crank pulley. Steeda CAI, x pipe no cats, roush mufflers, steeda tune. I guess im a stage 5 too ! yay lol .. I was told i would only be boosting 8-10 with that setup i need to get a boost gauge. What rwhp did you get ? what kind of crate motor ?

well the crank ... ( 1 year ago by roush907)

well the crank pulley adds 4 psi and heres the list of everything team jdm 298 strocker block with forged internals, ported heads, stage 2 comp cams. 2.57 pulley, 90mm idler pulley, steeda cold air intake, with 90mm MAF housing, 10% overdrive crank pulley, AFCO heat exchanger, gt 500 fuel pump, kooks headers and x-pipe with magnaflow 3" cat-back, team JDM custom tune, QA1 adjustable rear shocks, control mounts, lower control arms, 3.73 gears, and a wideband.

and to tell u the truth i dont remember the hp i was at and when. now im 550 to the wheels on pump gas and on my 100 octane race tune im gonna guess 580?

thats a pretty high ... ( 1 year ago by PureBred427r)

thats a pretty high number. Have you run it in the 1/4 yet ? i got a 12.7 in mine first time at the track. I work at a shop here in ga so ill do some more mods to mine eventually but its not cheap ya know ! thats pretty crazy though 550 to the wheels. mines 402. do i guess you gained 150rwhp from a cam, and a small bore, fuel pump, MAF and crank pulley. I wonder if that supercharger is running hot with that much boost.After all it is a baby charger.

yo i saw on your ... ( 1 year ago by PureBred427r)

yo i saw on your other page a comment saying the 427r runs a 12.2 stock, its 13.0 flat stock. Your in alaska ? Thats tight yall have those organize races right on the side of the road. Wish we could do that in atlanta.

well i have the ... ( 1 year ago by roush907)

well i have the afco heat exchanger for the heat problem. no i havent run it in the 1/4 yet but tis summer i will

What exactly is a stage 5. I know its engine/supercharger upgrades but what exactly

2.57 pulley, 90mm ... ( 1 year ago by roush907)

2.57 pulley, 90mm idler pulley, steeda cold air intake, with 90mm MAF housing, 10% overdrive crank pulley, AFCO heat exchanger, gt 500 fuel pump, kooks headers and x-pipe. well in reality it would be like stage 3, considering i was stock but roush does there shit wierd andya

WOW that mustve been a shit load

That seems like ... ( 1 year ago by Billboard2001)

That seems like realllly low estimation for pump gas(~90) --> 100. Where did you get your initial dyno from (the 550)?

hey i got a lot ... ( 1 year ago by roush907)

hey i got a lot more stuff on there now. but i dont have a dyno up here, but thats what team jdm told me

I know there's no ... ( 1 year ago by Billboard2001)

I know there's no dyno here in fairbanks (you should consider going to anchorage and actually dyno'ing it) I'm sure you'll be suprised on how high your guesses were. Your stock car being 427 hp at the crank, not wheels. And I'm sure being blown adds a good bit, but once again, I would bet a large, large amount of money that this isnt to the wheels. A stock gt500 puts ~415 WHEEL hp on a dyno, (for a drivetrain loss of about 17%) So if you factor that into your calculations, its just alot lower

not to be an ass or ... ( 1 year ago by Billboard2001)

not to be an ass or anything. I just think that your over speculating on your hp estimate

i see what ur ... ( 1 year ago by roush907)

i see what ur saying, but i now have a fully built 298 stroker motor from team jdm with heads and comp cams, and 427rs put 386 to the wheels. and i thought gt 500s put 440 to the wheels at 15% drivetrain loss?

hmm. ( 1 year ago by Billboard2001)

hmm.
Yea, it very well could lay 440. It just depends on the dyno brand (see mustang dyno vs. dynojet, the post huge differences in numbers :-(

Wow man u came ... ( 11 months ago by rsx2006ss)

Wow man u came along way since we last race...sweet....haha I ditch the supercharger and went turbo ..I only put out 279whp with the supercharger..now with the turbo I'm putting down 401whp on a conservative tune only on 12psi...check out my new vids
