R34gtt cooler into R33

[Chief]

Hi 97r33gtst-typeM,

When you dyno'ed, were you running at stock boost or above? This may make an impact on differences in output.

Like I've said before, I havent figures to compare before and after new cooler, but I could definately tell the difference (Im not just talking about the greater induction noise; with the 34'cooler in, it is feeling stronger). Like you said its not 20kw stronger like a FMIC - this goes without saying, but seeing that I could feel a significant difference I would say we must be talking about a 5% improvement at least.

That would be about the 8-10rwkw area which kinda sounds like the improvement sdm33 got. This may be felt more so with boost levels above stock where the lower volume and efficiency(?) of the stock cooler being less able to support higher boost and power levels. From what Ive read, the 34's cooler has 50% more volume than the 33's and is more efficient(how much more Im not sure).
