RS2 - a new lease of life

[Jamo]

Ross speak to JP about his reclocked 7a and forget about rs2 cams

[A80Avant]

but it seems that he doesnt have 7A cams Jamo! IF it is to reclock existing cams, and there is a good solution, fine, i agree. But if you just want to use stock stuff, maybe audi knew what they were doing

glad to see everything coming together Ross....you will have to keep me posted about your clutch...

[Jamo]

I know he hasn't that's why I said speak to JP about *his* 7a cams

You might as well keep stock cams with the turbo you are getting.
You will retain driveability down low, and not lose a whole lot up top.

Of course, 7A cams would be a lot more aggressive on boost, but losing the lows isn't worth it if you are going to use your car in town driving.
I have now tried 7A inlet and exhaust, 7A inlet only and 7A exhaust only. I'd say either go both, or just go stock cams.

An alternative, which I found pretty nice, was to use NM cams. IIRC they had slightly longer duration and lift than stock ones. Much closer to stock cams than 7A ones, but give a bit extra up top with not much loss down low.

But really, if it were my car, I'd just keep stock or ADU stock cam setup. Even on a GT30R car running 2 bar to redline it was very nice to have stock CR and stock cams, because of all the pull down low. Of course it wasn't as fast as it could be with only 15 deg timing up top, but power is really not everything, it was very driveable even around town.

ah i see your point now!

@ Prj,

While we are at this, what is the laymans description of the differences between a set of ABY cams in Ross' engine and a set of ADU cams in his engine?

Thanks.

[Jamo]

Only the rs2 exhaust cam is different, never seen the big thing with rs2 cams as especially with garrett turbos the induce surge where the stock aan/any don't, edit saw prj post wow I agree with it

[A80Avant]

did i mention that i like rs2 cams yet?

By the way, i believe some porting of the heads would reduce any kind of surge anyway.

I like rs2 cams I sold 4 of then for big money however they suit the kkk turbo range best
repo has had results on them after clocking them with an adjustable sprocket Brams rocket for instant
Mrc will tell you they are hell with a 3071r
I just think buying a pair of 7a and having JP or Prosty reprofile them is better than looking for a single rs2 exhaust cam for the same money

[Jamo]

Morning Ross!

[A80Avant]

i dont disagree, if you get them reclocked or reprofiled, they will be better, but as i said on another thread, on my previous setup, surge issues were minimal with vems, and without a ported head.

If i think of this correctly, if the engine is able to digest more incoming air(ie from the turbo) at lower revs, then the surging will be reduced, isnt that correct?

[Jamo]

I agree Vems gives you better control in terms of on your setup you had instant gains but let's face it Ross won't be switching to the dark ecu side!

[A80Avant]

That's true also.... The force is strong with this one...
