Re: Anti pump up lifters
Hello Bill!!
this is question wich i have given a lot of thought. I have heard at Competition cams hydraulic rollerlifter will go over 6500 without "pumping" of course its depend of how much you have valvespring ,but reducing the mass of valvetrain should help a lot,like titanium retainers ,lightweight pushrods etc.
I have tryid to hear comments what kind of results people have had but know one seems to have highrev hyd roller can engine???????
Lets hope this topic would bring more opinions

Re: Anti pump up lifters (bill mcdonald)
Why do you need them? Most of the after market hydraulic roller lifters are designed to handle higher rpms than stock ones but the stock lifters shouldn't have any problems unless other mods require much higher rpm to make power. What are your other mods?

Re: Anti pump up lifters (bowtie racing)
For what it's worth, I have seen many Hyd/cammed engines go way over 6000RPM. I sure hope my new engine pulls past 6K. There are alot of factors that effect valve float, and different combo's will behave differently from others.
