Really impressive F4R rolling road results from SRR

[Dan@SJM]

Yes, it's now using std cams with mikes timing

These engines do vary a lot, on your car that might be getting close to the maximum it will do, from what Ive seen the retiming only gives a few bhp increase and perhaps half a dozen lbft, its really not a huge gain. So if you have already paid for mapping its probably not worth it now.
So this one is just not a very good engine, was only low 160s as standard I bet, they vary more than any other engine I am familiar with, when I first started getting into these cars I was gobsmacked to see how much the F4R can vary from one car to another even when the cam timing is definately the same on both and they are both mapped to same standard etc.

Wow really?
i'm very new too the world of RS clio's, but recently had my completely standard 45k, RS 182 RR'd and it made (apparently) really good figures, this thread has got me seriously unsure now though reading about others and variations in rollers etc.
