They are lovely, My brother has an e46 (i expect its the same tbs) sounds amazing.

I think the M3 EVO and E46 have essentially the same engine give or take with minor changes

just to give a bit more info on this. the car is a 205 and is purely used as a track car, and cant decide which route to take the options are
1 fully forged N/A engine from Ridgeway racing engines
2 forged supercharger set up
3 forged turbo set up with proper dp engineering manifold etc

If you have the cash id go turbo. What sort of power are you after? As tue low boost supercharged ones use standard internals and can make 260bhp.

On that basis, i would say supercharger Thumbs up

Hi I am running a 206 rallycross car with a charged GTI6 motor with steel rods and forged pistons (£950) fitted with with a Rotrex C38 supercharger (£1600) and a Lynx fitting Kit (£800) Omex management (£600) new injectors (£500)
Steel headgasket (£120) and currently its at 300 bhp but once mapped correctly should be 400 + bhp

So for the best Charged engine you are looking at around £4570 but i would factor in another £2k for exhaust mapping Lsd diff ect

Even with just the 300 bhp its rapid so looking forward to getting it mapped next week to 400+ bhp

Marty

The supercharger system has been reliable just my right foot and cooling issues have been a problem when racing as i am on to my 3 rd engine.

The first one dropped a valve and destroyed itself
The second one overheated due to mud in the radiator and i didn't stop so it picked up a piston
The third one is going ok since moving the rad to the rear of the car and its currently 300 bhp and should be 400+ bhp next week but it drives like a normal car at low revs.

This is probably a really dumb question but why do you think they went for turbo's in F1? Could they have gone for superchargers instead?

its not just a straight turbo as one would normally think of one, it also has energy recovery and boosting capability in the ERS system which is powered from the turbocharger's spindle, essentially its an electric turbo/supercharger!!

F1 is not normal. Its a 'money no object' 'anything is possible' race. Things that have been researched and developed in F1 is beyond anything a normal person will encounter. But the reason is for a smaller capacity cc. Thus giving more economy and less emissions iirc.

Looks like supercharger is the way forward, looking in to a 300bhp forged set up which should be good fun.

Well that depends....

I'd say no if a circuit motor. If charging and forging why only aim for 300?!

In my opinion a Rotrex doesn't give the torque that you need.

Has the torque been limited somewhat with the rotrex setups though? Dunno

The gearbox is the main problem, turbo or supercharger there seems to be no cheap way of getting a bullet proof box Doh

No they don't seem to make the torque an eaton does or a turbo lump does.
