I noticed an issue tonight while I was power braking with a friend. After a certain rpm, my vortex kinda lames out, like it just quits screaming and stays at one rpm. Is this normal or is something off? Now I know that power braking isn't the best and I never do it, never really have too since this car will roast the tires without the brakes but can anyone give me some in site in what's going on?

 

Bumb

 

If your spinning the tires at WOT is it possible you're hitting a speed limiter ?

 

On a carbed motor?

 

With a carved motor? I'm running hei for a distributer so I didnt think I had a speed limiter,

 

Sorry, if you don't have a ECM then obviously you don't have a limiter.

 

Will have to think on this one a bit. What rpm does it become stationary?

 

Not real sure since I'm running the original v6 tach still but its around the top of first gear I'd say 4500 rpm?

 

Could be a valve spring or hydraulic lifter issue.

 

Didnt think of that but im running a stock cam with upgraded valvesprings( alex springs) so I didnt consider that, what the motor does is it revs alittle higher than normal then drops downn to where it stays till I let off the brake then I think it comes back up to its higher rpm. Would over tightened rocker arm nuts do this?
