Markus - You need to go for a trip to Perfect Touch mate.... 1.4 bar redline!!!! <img src="/forum/images/graemlins/smirk.gif" alt="" /> <img src="/forum/images/graemlins/shocked.gif" alt="" />

He He... what's wrong with that Si as I've had 1.3bar on my marshmallow internals <img src="/forum/images/graemlins/wink.gif" alt="" /> I'm not sure the turbo can flow 1.4bar at redline very efficiently though but it's worth a shot <img src="/forum/images/graemlins/laugh.gif" alt="" />

But is the car at full performace at that RPM or is it 3500 - 4000rpm and its really going? This is what i think people need to state when they are talking about spool up / performace / lag.

My huge turbo would be going at 4000rpm on the button, but yet i could have 1.4bar by 3000rpm but not actually be seeing the performance side of it <img src="/forum/images/graemlins/smile.gif" alt="" />

That's definately the crux of it Begbie, it doesn't matter when your turbo spools up because it only really counts when you are "on boost". I know Joe's RS spools a fair bit quicker than mine but we actually come on boost at near enough the same point... he's a car length ahead at this point though <img src="/forum/images/graemlins/laugh.gif" alt="" />

You're right there Begbie, it can often be misleading.

Although I get 1 bar of boost at 3000-3100rpm, the car doenst 'get going' to nearer 3500rpm, and then its too quick to spot <img src="/forum/images/graemlins/laugh.gif" alt="" /> <img src="/forum/images/graemlins/laugh.gif" alt="" />

The hybrid certainly was quicker by a few hundred rpm here <img src="/forum/images/graemlins/smile.gif" alt="" />

The only way to compare impirically is to get a fully loaded up dyno and run the cars. Your max power will be down (and your setup will dictate how much you lose), but you will be able to compare when you are actually making power rather than just being spooled up.

I have a dyno graph of my car on a loaded up dyno - it only made 420BHP (down 40BHP) but the turbo spooled up as it does on the road and you could see where it spools up compared to where you are actually getting the power by comparing the boost to the torque or power.

I have the RS and straight induction.

1 bar comes in at close to 3000rpm, but as Docorfrag pointed out it does not realy start to pull till 3500rpm - which is now when the clutch slips in 3rd 4th and 5th <img src="/forum/images/graemlins/frown.gif" alt="" />
