hello friends. I want to know the feedback from users of kleemann camshafts. I bought new shafts. tell me how the power of my w211 e55 will change? today I use pulleys 175 and 77 and good cooling. my travel time is 100-200? does anyone have experience with these shafts? do you feel an increase in power?

 

Hi, I use Kleemann cams in my car along with mid tube headers, 80mm throttle body, and a stock pulley which has been milled to 88mm. My lower crank pulley is stock. I fiddled with the cooling and stuffed in 3 heat exchangers and a Pierburg CWA100. Depending on ambient temps my car does 100-200 kph in 7.1 to 7.7s.

Mist noticeable difference with these cams is, they make a tad less torque than the stock ones, but the power keeps going up till 6500rpm. The stock cams drop power after 6100 rpm roughly. Last summer I was on the dyno with some other 55. One guy had a similar mod list like mine and I've attached both power curves.

Based on your measurements, I see that there is more horsepower on the stock shafts. And it is 581. Correct?

 

Top dyno was from a different car with stock cams. Mine is the bottom picture with 572hp. The other car had more HP due to running more boost. He had a 172mm crank pulley and stock upper pulley. Mine had a stock bottom pulley and 88mm upper pulley.

You can't compare the numbers between the two cars, but the power curve itself.

 

thanks friend i got it
