It may just be my perception but I feel that my car is loads more powerful in the 5500-6500rpm range if I have been accelerating from 4000rpm (or under) in that gear. In other words, if I change gear quite early, and the car is at 4000rpm, I put my foot down and the car accelerates nicely and by 5500 it really pulls.

But if I am holding speed at say, 5000rpm, going around a corner, then suddenly accelerate, it just doesn't feel fast. That same 5500-6500 that felt so good before is not there. I checked the boost gauge and I still seem to be hitting my boost target, but the car just seems slower.

Any comments, similar experience?

 

probly just waiting for the turbo to spool up m8. ?

 

That's what I would have thought, but the turbo is spooled up as I am full boost, it spools up between 5000 and 5500 but 5500 to 6500 seems slower that if I had started spooling at 4000.

It's probably just that it doesn't give the kick up the backside as the torque is lower there?

 

How is you car setup ? To hold a flat boost target or vary by rpm ?

You are passing peak torque by c. 5000 rpm on a TD05H-16G

as you can also see from the graphs peak bhp is c. 6000 rpm
