Contour Enthusiasts Group Archives Forums Modifications Forced Induction Turbo and nitros ?combined?or more boost

I read alot about the turbos and would like to know which one probably would be better on the stock engine.

Turbo and 100 shot nitrous
or
turbo and 4 psi boost=10psi

I definitely get the turbo since more tuneable than the s/c.

It would seem nice to have all three but boooom would probably be the answer.

What are ya'll plans?

I hate to say this, but it seems you may not fully understand what you are talking about. I would advise that you study up on internal combustion engine theory, and forced induction (both turbo and super, and the differences) and how nitrous works.
I would love to help explain/clarify some of these things for you, but it would take a loooooong time to type it all, and I prolly couldn't explain it nearly as well as others.

fyi, there is a fantastic book on turbocharging out there called "Maximum Boost" by Corky Bell. It provides an excellent resource on turbocharging and the practical applications of turbo theory.

The turbo kit we are putting out will be able to provide as much power as the stock internals can stand. Anything past that and you start to chew metal. You might want to lay off the F&F DVD for a while

well the only reason I mentioned the 100 shot is because isn't worldtour pushing 10psi with the water injection and having no problems. That didn't sound crazy to noneone. Especially when the turbo only pushing 6psi what 4 more psi =10psi the same as s/c. Or the 300hp at the crank with the 100 shot at the crank equally 400 hp isn't there only one duratrac out there with 450hp on stock internals with a turbo used on a race car. I may need some knowledge on turbo but at least what I saying is going be tried I bet.

I think you need to understand engine internals a bit more.

That sort of power will require much stronger engine components than the stock parts.

Worldtour is running on the ragged edge of what the stock block can handle, and he is well aware of the fact that one of his con rods could go at any time.

Saleen had roush build several 450hp supercharged motors for the Saleen Contour, and Saleen destroyed at least 6 of them in a very short period of time (this is at least partly why saleen never produced thier contour)

I really think you are looking at things the wrong way, you are trying to throw parts at the car to make it faster. Decide what sort of HP you want first, then study up and find out what it will take to make that kind of power.

Worldtour is running stock Vortech boost. (8-10ish - random it seems :rolleyes: )

Water injection is to prevent detonation. Nothing like Nitrous...

Around 300HP at the wheels (365ish crank)

Turbo kit is preset at 8psi.

Comparing the turbos 8psi to the S/C (8-10ish psi) is pointless without knowing how much CFM either one is flowing. It's not psi, but CFM that is important...

There is NO 450HP stock Duratec.

Duttweiller built a 450HP turbo Duratec but used a few custom pieces. Forged pistons & rods being a big part!

I think I see what you are suggesting, are you suggesting you use Nitrous like a water injection system? It does work and has been used, but not on contour/mondeos. Theory being that you use a small injection of nitrous to lower the intake charge, when used appropiately you can also use it to lower the turbo lag.

If this is what you mean then 100BHP would be extreme!

I think others saw what she was suggesting too, but that sort of power increase would be far above what the engine internals could handle for any length of time. Heck, just a 100 shot on a stock bottom end is close to the limits of the motor internals (let alone driveline parts)

What kinda internals might need strengthend?? (rods, bearings...) I know that the Duratec in stock form can't handle too much But it does allright.

my understanding is that the rods are the first weak point.
