is there anyone who has tried to get other camshafts an valve spring to get higher rpm . and are there some who can tell me what the ome degrees is
Schrick made a set, not sure if they still do
They do but the question is how much i get out of mount them ? Schrick inlet 288* or 292* outlet 274* or 278* But whats is the original degree ?
The schrick cams are good but they are made for the higher revving V10s that go to 8400rpm. The max motor speed your going to see is about 6800.
The cams in the S6 are low end cams. I can look but apparently back seveal years ago someone put on a set of heads from a lambo and according to them they lost all low end TQ. I would try to email schrick and see what RPM range the cams are made for before you worry too much about much else.
Another thing to keep in mind is that the whole engine has to be designed to hit those higher RPMs.
so with the cam lobing and phasing, that obviously controls intake and exhaust - when air is going/coming, how much, and how fast. then you have to adjust fueling accordingly. and your piston bowls have to be designed to combust properly given all of the above in terms of both timing and the actual physical fuel/air mixture that you’re getting. and your entire drivetrain needs to be able to support revving that fast, lest everything fatigue prematurely or hit a critical speed (resonance) that causes a part to let go.
not to discourage you from investigating - but realize that raising the RPM may not be a good thing if the engine components aren’t designed for it. if you were to take an R8 block from a salvage vehicle, that would probably be a much better option because those parts will be designed with the higher revs in mind.
edit: now working for an automotive company, i have a much greater appreciation for these kinds of things 
Said it perfect the best example is the high revving 4.2 in the RS4 Vs the Q7. They both have the exact same block but the RS4 has different timing chains… bearings… intake manifold… camshafts and transmission to handle the extra rpm. It’s no small upgrade.
I will give you that right. I’m just looking for opportunities to get more hp out of the engine. the things i have done are: 10 new injections, Coil Pack, JHM Intake Spacers, Spark plug, kn filter new intake manifold, cylinder head cnc machined for better flow and i make header what else can i do.
The JHM ecu and tcu tune unlock a good amount of power. The head work and the exhaust won’t do too much without a tune to support them.
fits jhm tune to my octane number 100 (RON)
is jhm tun not the same as if i get the car on dyno and made a program after that
Many people have tried messing with tunes themselves and ended up not doing to well. The biggest thing you are missing are the ECU/TCU tune from JHM. I’m willing to bet those will be exactly what you’re looking for.
Exactly great point. V10S6PA
@noerregaard I and so would all of the other JHM tuned guys suggest you go with JHM. We have all seen dyno tuned cars in the past from companies like APR claim big numbers only to show ZERO difference in acceleration times. I’ll have to search for the customers name but I think there was someone in Australia that got a dyno custom tune that claimed BIG gains on the dyno to show almost no real difference in acceleration. That user switched to JHM and picked up almost 1 full second in his 1/4 mile acceleration times and an impressive drop in the 0-60 times.
Those reasons and the fact that JHM actually has development 5.2 cars and they are supporting the platform is something to strongly consider when thinking about the tune. I do believe there tune will cover 100 RON. Several people in Europe have there tunes for things like the S8 and other NA platforms JHM is in like the RS5
