Hi Guys.

Tech question for the guys who've played a lot with Vcam.

I've currently got a Step II, 264 in 8.7mm lift.
Making around 700rwhp with an EFR9180 on a slightly ported head with 1mm oversize valves.

I was wondering if anybody had compared the Vcam Pro's 264 10mm profile and experimented with the gains it gives.

on paper it seems like a very tiny increase, but its marketted by HKS for higher levels of power etc. Perhaps it has a much more aggressive profile and could flow a decent bit more than the Step II.

Has anybody ran both of them and can report of the power difference with a single turbo?

Cheers.

Pretty sure the difference in response varies with turbo. UP Garage in WA, USA has dyno graphs on their facebook comparing step 1 and step 2 VCAM with some turbos, the difference can be huge in some turbos and significantly less in others.
