First post!
Right everyone I'm new to the site and this is my first post so hope you don't mind this techie question.
I recently had my car (clio 182) fitted with the Ktec low pressure turbo conversion.
When the fitting etc.. was being carried out I was told it would be running approx 220bhp at 7 psi (0.5bar) boost.
After the fitting I took the car to RStuning for some tweaking of the original map, as it was originally done on Seans 172 clio. On Pauls rollers the best he could get was 205.9 bhp (the print off confirmed 0.5bar of boost)
Moving on, there are a couple of supercharger kits being developed for clio's in both high and low boost formats. Both the low boost conversions are claimed to be running at 0.5 bar yet putting out 250+bhp.
So the question is what is the difference between turbo boost and supercharger boost at 0.5 bar that should yield such significant power differences? Considering both conversions use standard internals, CR's etc..
Surely boost is boost?
From all the research I've done, a turbo should have the highest gains due to the fact that it runs from exhaust gasses.
Where as a supercharger has to sacrifice some of the bhp gained, due to the extra drag placed on the crankshaft to turn it.
I did a search on google about this and all I could find was various groups argueing which was best.
Hopefully some of the experts can break it down into simple terms for me.
