You guys have issues. SGC posted a vid of his dyno. And that's what this thread should be about.
Any ways. Stock boost for 600 cars is 0.9 bar. Stock boost for 65 cars is 1.5 bar. These numbers are straight out of MB repair/tech manuals. From personal exp. most cars stock are right at that number or slightly lower.

I didn't realize the stock 600s pushed so little air.

So a stock 65 runs 1.5 bar that's 21 psi, and TMC M5 says to get 624 RWHP
he is running 22 psi.
Ha Ha Ha HA
That's a WHOLE pound more..
Thanks for the accurate info.

From my perspective, I don't pay much attention to anything other than what my car does in the quarter-mile and how much power it makes on the dyno. I leave the rest for the tuners.

Don't tell anyone, but this thread has been a conspiracy to give you inaccurate boost numbers to make sure that if you have a V12 BiTurbo, it will be slower than everybody else's.

Surely SGC you know what boost you are running now, I have been accused many times for not being interested in facts and figures.
My guess is you must be running 25 psi, and I am not sure whether there was adequate cooling.
I do have a V12 TT but it's stock, extra torque I think would make it less fun in our type of weather. Still everything is quiet! shame I was enjoying it.

When I had a Buick Grand National years ago and had a boost gauge in the car, I could tell you boost numbers to the pound; however, with the Benz, I've never paid attention to it since there is no boost gauge in the car.
However, this thread has peaked my interest. It is my understanding that my current tune runs a peak of approx. 1.5 bar. It is set up to run on 93 octane because I drive the car every day. Maybe there is more power on the table. I will ask again and get definitive numbers to satisfy my curiosity as well as yours.

I think you need to update the 1/4 time and ET in your sig! Congrats!

manual according to him.You say your car PEAKED at 1.5, so that would probably drop off slightly. So how is it possible to get 624 rwhp on 1.5 bar.
Maybe you should ask the operator on the dyno what it was.

You are right, I should have posted the below turbo map as an example, its easy to see for any gearhead that even a slight increase of e.g. 10% in boost is accompanied by an increase of as much as 20% in temperature etc - but its also easy to see that what really matters is airflow, not boost.... but now I start to rant again

It looks like a 1.65 60'. I think in optimal conditions it could crack into the 10.7s. I am not sure the FL weather will cooperate with that. It would great to see Steve's car at MIR. But that is a long trip to pick up a 1/10.

You're exactly right on the the 60' foot - 1.65. Hoping to get some cool air down here without rain before it starts warming up for spring.

Hi, Dsmed says stock boost for 65 cars is 1.5 bar, that's straight from the MB
manual according to him.You say your car PEAKED at 1.5, so that would probably drop off slightly. So how is it possible to get 624 rwhp on 1.5 bar.
Maybe you should ask the operator on the dyno what it was.

It also says 730 bhp at crank, how do you get that.
So if you believe the 730 at the crank that's an extra 130 bhp for an extra 4 psi
Upping the boost is the only way you will get significant extra BHP. Before you say it I realize a bigger engine will produce more bhp with extra boost than a small one, however there seems to be a lack of maths, more guess work. Was it really only 4 psi more than stock, I find it hard to swallow, 26 psi maybe!
