HANG ON a minute, I might still supercharge mine... is it possible to do both? at the same time?  SUPERTURBOCHARGE...

Just for you mate.

I realize the supercharger draws a small amount of power to drive it but the boost comes on earlier in the rpm range.

I think you will find it is not a small amount of power, and could actually be as buch as 40 to 50 hp

Please correct me if I am wrong, I am sure Someone WIll!

I don't know exactly how much power loss you would have, there would have to be some. As the boost comes on from the moment the engines rpm increases it would'nt be to long before the boost would counter act the loss, and show a power gain. And can you imagine how quickly the turbo would spool.

sbr79, Already started designing plans

Do the same to N/A XR6 how could it not perform as good as a turbo.

Easy, the centrifugal supercharger does not produce any where near the same boost pressure (mas air flow) in the low to mid rpm range................the turbo will murder it on the strip and street.

Peter,

Can't you overdrive a supercharger to resolve this issue?

Or is it not possible with centrifical superchargers.

then you have overboost up high nothing like a variable drive supercharger commonly known as a turbo!

still got that one for you to look at macka?

That RX4 is mental!!!!

Its hard to put to sh*t on a blower install job on a XR6 when theres been bugger all development on the blower compared to the turbo.

How many moded Turbo's Vs XR6 and XR8 Superchargered cars are out there?

I love the Turbo, but at the time I got my N/A car the turbo was 9K more, and 9K on a blower package gets you a bit more than the stock 240kw me thinks, more like 240+ at the bags (and change).

It was a happy life, till I bothered talking to insurance companys......to all the supercharged guy out there what are you paying to cover your beasts?

Its only time till I get a blower, then a re-build to harden up the guts so I can run small shots of NOS with the Blower. The sound of a super-charger at high or low revs that's a noise you can't beat it.

Macka the real problem with centrifugal blowers is you need to gear the blower around the boost pressure you will have at red line.

In other words if you want to run say 10 PSI at approx 6000 rpm the centrifugal type blower will only produce something around 3 to 4 PSI at 3000 RPM, compare this to a turbocharger...............the turbocharger being exhaust gas driven will produce more like 8 PSI at the identical rpm (3000 rpm) hence much greater mass air flow............higher torque and power across the entire rpm range than a blower.

too tue that is how its done as a norm you can also set it up for low down boost and bleed the excess off which is wastful and the charger life is reduced greatly!

roots or screw type is the go for the road but as turbos already produce too much low down torque this on a high comp will be worse!

macka or anyone as ive said b4 im happy to helpout if need be!

[Lawsy]

I was pretty sure they were thinking about using a screw/positive displacement type charger....

They're more fun I reckon
