On a Standard ECU (so standard boost & Ignition settings) LET we fitted an XE Inlet Cam with a Vernier retarded 7 degrees I think it was and the engine put out 240bhp!!! So YES it does make a difference. More so on an engine running Higher boost im led to believe. As mentioned... read MAXBOOST. Great website

Nope, as the distributor is driven by the camshaft. You could actually make it worse in theory.

would a vernier pulley sort that out

Total vauxhall did a test with an engine and various rolling road tests with standard cams, xe inlet cam etc

read max-boost or ask on vaux-sport. You wont get a technical answer on here, and it does work.

So heavily tuned, it will add around 30bhp?! hmmm.

i think that the XE exhaust cam is too aggressive for the LET and would cause the valves to touch the pistons so is no good.

Thought it may be something to do with that, but why not the XE exhaust cam in then?

I think 10-12bhp is a bit optomistic TBH.

ive got the feeling that it is slightly more aggressive/has a slightly longer duration so as a result there is more air in the combustion chamber

Have people actually seen 10+bhp off this mod? Even off a standard engine?

I'm just curious as to why it adds so much? or is there more to it than just shoving in the inlet cam? IE mapping?! pullies?
