400rwhp and I want more--give me ideas

vorteched2000GT · Dec 30, 2003

I have the following ENGINE mods:

305 Big Bore with forged internals
BBK LT' w/Cats
C&L 80MM
P&P heads
Bullitt Intake (untouched)
Bassanii Catback
Vortech SQ Blower with smaller pulley (10lbs boost)
Steeda radiator
FMS 42lb injectors

Other mods include:

Steeda Shifter
3:73 gears
Aluminum Drive Shaft
17x8 fronts/17x10.5 rears/nitto drags
MM full length subs
boost and fuel pressure gauge
2003 Cobra tank and pump

I think that's it.

My goal is 470ish rwhp on a conservative tune, as I don't want another rebuild.

Although the car is not a daily driver, it needs to pass the sniffer so cams may not be an option. Pumped gas is also a necessity. I was thinking about a powerpipe and aftercooler.

I would upgrade to a T-trim, add an intercooler, powerpipe and let Tim tune it.

You can ask Tim (Cobra Killer) anything you want Here

'96&'01Stang · Dec 30, 2003

You could also P&P your bullit intake

Wills Black 98 · Dec 30, 2003

yeah upgrade your blower defiantely. or spray on top of what youve already got.

vorteched2000GT · Dec 30, 2003

Why should I have to upgrade the blower when vortech says it will support up to 680hp, far less than I desire.

Screwed2V · Dec 30, 2003

So, with a 5.0 stroker, an s trim, a bullitt intake and all the other mods your'e only making 400 rwhp? Something is amiss. I made 437 with the stock motor, s trim at 9 psi, bullitt intake and magnaflow exhuast. You should be well over 400 rwhp with what you already have.

What is your torque at the wheels?

Wills Black 98 · Dec 30, 2003

put a new pulley on it then at least go up to like 15 pounds!

vorteched2000GT · Dec 30, 2003

The torque peaked at 420. I have a very conservative tune by Alternative Auto. The hp actually peaked at 419, but that was at the limiter, it maintained 400 at 4900rpms to the the peak at 6200. I'm sure the power is low for the combo, but Lidio is know for his conservatism and making engines last, two things high on my list.

Wow. I'd be cuttin' somebody. I'm sure that built motor can take well over 419 rwhp.

Atlanta_GTer · Dec 30, 2003

Uhhhhh.... I'm confussed. If I was only putting down ~ 400 rwhp with that setup, I'd be on someone's ass. A "conservative" tune with that setup should be closer to 475+. Not sure what gives here?

Seems extremely conservative to me. Tim(Cobra Killer) had a stock 99 cobra w/ a vortech SQ put out 470rwhp with nothing done to it except one of his special tunes...

That's what he considers conservative for a built motor?????

GinoGT · Dec 31, 2003

I'd bet Tim could get a nice amount of power out of that engine without even turning a wrench. From what I've heard, his tuning is almost like voodoo.

BlackStripes · Dec 31, 2003

what they said, for all what you have, 400rwhp is way low. You only need another pulley and another tune.

Just for the records, on a stock engine, stock exhaust manifold, stock intake, a 3.33" pulley and some methanol , i make 424rwhp and i race my car ALL the time. Don't be afraid, your engine can take way more than what you have now.

Bone Racing · Dec 31, 2003

VT blower cams
alot of suspension

bryantd1960 · Dec 31, 2003

Get rid of that C&L and get a Pro-M (or at least a 90mm Lightning). That should help a lot because those #'s are low for what you have.

Screwed2V · Dec 31, 2003

Can you scan your dyno sheet and post it? I'm interested in seeing the torque curve. Thanks.

vorteched2000GT · Dec 31, 2003

I can email them to someone to post.

With a big bore motor i would expect a LOT more power.
I run a stock bullitt intake,3.1 pulley no cooler, and pump gas. And my block is only .20 over.

I can understand conservative.But 400rwhp .Mines conservative(only 14.5 degrees of timing).Plus a c&l is NOT a good maf for a blower car.
With the same basic setup as you have now (except running a powerpipe with a 3.33 pulley) i made 481rwhp.

Cams is a main key and with the right tune and cats it should pass the sniffer no problems.
