Except for the side exhaust ports, the turbo back pressure will cause the end plates to swell around the exhaust, and the engine will fail shortly after the exhaust ports are damaged.
Any turbo really needs a bit of porting work for any hope of reliability, due to the extreme back pressure between the exhaust port and the turbo.

 

turbos tend to be alot smaller but supercharge give you alot more low end power

 

Surely you measured this on several turbo cars and compared it to your exhaust pressure levels, of course, considering similar mass flow

Or you assumed?

 

Actually, "I" did neither:


Theory on Turbo Renesis failures, by Pettit & Forcefed Racing

 

This could be argued...... and it has been....

 

Oh, "theory" from people producing supercharger kit

Mismatched combinations doesn´t count. And without comparison on same power level - which on its own will need to be higher in SC engine to drive SC, you are just repeating same BS, same applies to "usable" power of SC engine vs. "laggy" turbo

 

Actually, Forced Fed Racing is only into Turbos, but you already knew that.

 

Actually, you can´t prove your claim about extreme back pressure and just repeating same BS on topic, which you don´t even understand

 

Why not just enlighten everyone in detail with what is wrong with Pettit's white paper?

 

Its one example of how not to do it. But everyone takes it as gospel against turbocharging Renesis. Surely, turbine restricts flow, but not every turbine and housing combo is same... What cracks me up is that some supercharger guys are acting like their exhaust system doesn´t have any restriction, but every turbocharger surely has "extreme backpressure"

 

I see where you're coming from. I think if you have a setup, turbo or sc, that is reliable for your circumstances and produces the type of power you want to make than that's really all that matters.

 

Fair enough

I just hate when someone claims something, which isn´t true and even doesn´t know what´s happening... but that´s interwebz

 

Thx guys for all ur replies... Some good info and arguments... Made me understand more things, yet more confused on what i shud get. Is there anyone in here that actually have/had a sc or turbo rx8?? Thx!!!!

 

LOL
Ummmm basically it's a personally choice.
Make one and go for it.

There is no clear cut winner ...... but many will tell there is.

<I have turbo>

And yes there are many members with both.

Go to the Performance section have a look around

 

I'm a turbo man myself..... wonder how many members have had the privledge of driving a SC and Turbo'd 8 with nearly the same power levels??
