Does the vr6 have a flat spot
« on: 13 April 2013, 15:15 »
I was wondering if the vr6 has a flat spot at a certain rpm as its only got 2 valves per cylinder as like the 8v or does the dohc help solve the issue

What?

Do you have a vr6 with a flat spot?

No engine should have a flat spot.

Again every engine has a powerband.

Say a engine reaches maximum bhp at 6000rpm. You want to keep the revs between 5000 and 7000rpm (powerband)

Do you mean does a vr6 give you a kick up the arse when you hit a certain rpm? No it doesn't as the bhp pick up is very smooth and no sudden kick in power throughout the rpm range. It also makes a lot of torque low down the rpm that is also smooth.

Edit. (Miss read) No it doesn't run out of power up the top rpm.

The cam in the 8v is poor. I changed mine and it pulls right up to the limiter

I have a 8v i was just wondering if the vr6 would have had a similar curve but its a cam problem then why did vw opt for 2 valves in the vr6 instead of 4 was it a overcomplicated design or would have been to advanced in its time or was it a money thing

Technology. It was designed in the early 90's maybe even thought up in the late 80's at the time it was a great engine and don't forget how cheap fuel was!

10 years later they made a 2.8 24v that came in the mk4 and the vag r32 engine.
