standard vs supercharged power figures

[Sam&Lewis]

can any one tell me standard power figures at the fly and at the wheels for a 230 model v6.

also just for an example what power would you expect to have if it was supercharged with standard compression running 14psi.

ours isnt running 14psi (i hope). just curious.


cheers

mike t you have a pm

I have responded!

I’d suggest the following

Fit a boost gauge first
Run no more than 7psi max at standard compression (this will involve a release valve or a reduction in supercharger gearing – not a BOV which you also have already I guess and still need)
A large Vortec can run 600bhp so it should be at 2/3 speed approx max
Do this only with a good chargecooler in place (inlet temp will be way to high otherwise)
Place an air inlet temp sensor at the inlet and when the inlet goes over 40 celcius retard 5 degrees as a safety feature (ecu switch on a motec).
Standard injectors will not fuel enough – 430cc or big greens will do or it will lean off
Standard fuel pump is to small and needs upgrading to a motorsport pump
A boost related fuel pressure regulator is a must or it will lean off under boost – this is a bitch with a standard fuel rail and I had a billet unit made.
A better oil cooler is a must as oil temps reach 130 under boost
It will make 380 bhp at 14psi mapped correctly with intake temps at 25degrees
At 7psi I would expect 300bhpish with similar intake temps

Your current issue will be intake temps at 100+degrees at 14psi with no cooler leading to a huge reduction in air density (less oxygen) and mapping to this has led to a reduction in bhp over standard – the colder the inlet the better.

It will blow up (they break ring two on the rear bank first) by detting under load at moderate revs if you do not do the above or run higher boost with standard pistons.
Turbo pistons are a huge help with a cr of about 8.5 and a larger height above ring 1 to dissipate the higher bore temperatures.

You have my no if you need to call
