don you make a good point but as the rpm gets more radical cant the cam get as radical to make the power in a differant rpm range??

Diesel Doc

The only class you could use that many rpm's according to the DHRA is super street.
The entire rotating assembly would need to be balanced. I would lower the compression and install the lightest pistons available for that many rpm.

Dwitt0187

yes super street is what im talking about

matego

You are 100% correct and that would be good if you could do a gear change 1/2 way through the pull. Since that is not possible you need the RPM's to get wheel speed in 1 gear. They pull into the meat of the power at the end anyway with a good set-up.

Don, I know you know this... just trying to add a little info.

They arent, 12v's still rule the 300' track, and will until the software comes out to turn 4.5-5k rpm, or people start throwing 13mm ppumps on the CR engine

Dwitt0187

the route of the p pump on the cr is taking away from the 3rd gen part of it. electronics can be tricked and once they are it is unilimited to what they can do. if you p pump it then you just have another p pumped 24v with the new head. and that has already been done by a couple people i believe there is a video on the diesel garage of a p-pumped cr motor

Hintz

Please explain. And you'll have a better flowing head

I don't think the 3rd gen rpm game is over yet.....

this is link the a p-pump 3rd gen i think the guy is a member on here search p-pump 3rd gen

Dwitt0187

picture of p pumped 3rd gen the user name is (p-pumped)

Kind of out of the power band.....yes.....4000RPM ...........sure

haloman

Can the CP3 supply adequate fuel at that RPM range?

Dwitt0187

one can't but i believe that 2 would have no problem as long as the lift pumps were strong enough

Bswope

Id almost bet that the Dmax croud could be a big help tuning that $8K ECM!
But im with Justin, i dont think the RPM gain is over yet.

i would really like to see 4800-5000 rpm that would suit me just fine. i dont really think you need 6000 rpm in our trucks, but then again i dont pull in the super street either.
