How to go fast on the stock motor? - 2003-04 Mach 1 Registry Owners Club

So, everyone seems to say that 450hp it about the limit and even then, its rough.

How can this guy run a stock 2v longblock with twin turbos, make 480hp/500tq and tim and mph say its fine.

Cuz...if its fine...then imma start saving moolah haha

The dyno run was dated 5/1/07. Lets see how long it lasts at that HP level.

He says he's gonna be at FFW in Houston. Maybe I better bring a mop and broom.

How much power the stock block can handle isn't a hard number. Whoever you ask, you will get a different answer. I've asked this before, but I'll ask again, that magic 450hp, is that to the wheels? Is that for turbo cars or supercharged cars? What about nitrous? Is that through a stick or automatic?

When you factor parasitic losses, you can see how a rwhp measurement coupled with a supercharger through an automatic could be skewed. Hell, 450rwhp through an automatic with a supercharger could mean 600hp at the crank. Whereas 450rwhp with nitrous and stick means around 500hp.

Well, if it is a manual, that helps. Turbo's are much more forgiving then Most SC's as that belt adds about 50-100+ hp at the flywheel and there is some back pressure on the piston to help the rod stay straight. The compression on the two valve is much lower then our 4 valves, so detonation may not be as much of an issue. And he is only at 9 psi of boost.
I am at 9.5.

Still, good luck to the dude.

He still has to be very careful about boosting at low rpm's/high load! (ie high gears like 3-4-5)

i'd feel safer with turbo'd 450hp than s/c'd 450hp.

I thought for sure with all the work he did on that engine that he would have obviously forged it. I guess not. I'm counting the days till explosion.

We still need drivetrain mods for the GT but the nearly stock 2V is pushing 445rwhp/428rwtq on 6psi. The built motor can take a solid 9psi and the driveline will be ok up to 500/500 by the time it goes in. This will be a street driven car that may see some autoX action and a rare trip to the drag strip.

The cr will be just below 9/1 and the cams are meant for TT's. The current motor came from a wrecked 03 vert and has forged pistons and cams. We are using a PP Bullitt intake that is the only thing moving to the new motor.

I'm thinking he may have a combo that could work. Sure seems like the TT's are easier on the whole car than what I expected.

You can go fast on the stock motor, that's not the problem. The problem is detonation under a power adder, nitrous being the worst. You can hurt the motor N/A if using crap gas on an aftermarket tune!

Using pump fuel at your local station is the number 1 problem when producing a high performance tune/motor now a days. You need to find/have good octane fuel all the time!

I guess you can look at 450 rwhp meaning someone that is careless with their fuel, tune, plug checking/gap/so on, and the factory motor still can be hurt, being the powdered metal rods are the weak link. Second, are the factory pistons top ring land thickness. It's a safe average is how I look at it.
