R8 V8 carbon build up?

Do the V8 R8's suffer the low power output and carbon build up the same as the B7 RS4?

Like to know about this too... I am guessing they do as they are FSI...

I'm sure someone told me that the R8's don't suffer from the carbon problem as much as the RS4's. Possibly because the R8's engine is dry-sumped and has a different crancase breather arrangement.

I did some research on this and what I found was that they do still suffer as do the V10's. I don't know if it's to a lesser degree or not.

My understanding was that any FSI style engine(direct injection) will suffer this as the fuel that would normally flow through the ports assisting in keeping the ports clean is not there... so carbon build up is inevitable?  Meth injection can help & forced induction reduces build up.

suffer from carbon build up??? Absolute balderdash..... according to some people anyhoo.

100%

With any DI car you will get carbon build up, its just one of the drawbacks from the design. But badly designed breather systems, egr, valve timing and other things can all accelerate the problem.

Good stuff Bruce

yes they do AFAIK

BUT, V8 R8's are faster than B7's as no matter how hard I tried in my bananana I couldnt beat iR8V8 in a drag

that was because the colour... not of being an rs4 instead of r8
