great times!!..does anyone know what some of the top d-maxes are making on #2???im sure its close to these times

 

The one I helped build locally ran a 12.36 @ 109.9 on #2 yesterday. It's a LLY.

 

when people do twins on the 3rd gens are head studs needed?

 

yes, usually over 45 lbs of boost you need aftermarket studs. they hold pretty well

hope this helps

 

I ran 50 lbs all year pulling last year with stock head bolts....thats 50lbs for about 20 seconds straight with egt's in the 1700 area
When I removed the gasket about a month back there wasnt even a hint of any cylinder leakage on the gasket.

So I would say studs are not needed in the 40psi area but they couldnt hurt either!

 

The 3rd Gens seem to be able to take more abuse in the head gasket area...most don't get o-ringed until past 65-70psi.

Of course my headgasket/bolts don't owe me a thing...they've hung in a lot longer than they should have

I thought I was abusing my truck hitting 1600*f for a few seconds one time. About 1300*f and 42psi boost is about all it see's now days.
I can't figure out how folks burn their motors up on these 3rd gens.

 

Don:

Congratulations on your times! These darn Dodge CR Diesels are definitely doing well now!

I know that I would easily be in the high 12's right now if I got a set of slicks. I ran a best of 13.45 1/4mi. about a month ago on a stock LP. and stock tires. I hit the dyno #'s with the Walbro and stock turbo. I thought about getting a set, but this is my daily driver, and I dont race it much. besides, I really like the stealth look it has too much. Nobody outside of a lifted/modded diesel that could see my stickers would know what I had.

 

My father and I seen most all the runs on Sunday and like Don mentioned earlier it is very obvious that something was limiting the top end. CR's are on a much more aggressive hp path than the previous Cummins motors. It really is too bad that nobody has figured out the electronics on the top end yet. When they do... I know I was watching a 11 sec common rail on stock tires getting with the program.

 

Steve:

I have to agree with you 100% about the Dodge Cummins CR Trucks! It is only a matter of time before someone figures out a way around the defueling issues. Steve,.......... can you work on that for us?? I also think that with the advent of the "upgraded" CP-3 Pumps etc. that the CR trucks might be able to rival the 12 valve P-Pump trucks. It will definitely be interesting to watch.

I am impressed with what I can do to my Chev with the EFILIVE setup. If a similar setup ever comes out for the Cummins the CR will exceed the 12 valves. And they will do it at a much cheaper cost.

 

Don- Bullydog has a tune that completely eliminates TQ management and the speed limiter. It also pulls much harder than the current Crazy Larry tune. It has not been released yet, but hopefully soon as track times will be much improved. Before this tune I could only launch with 2k rpm before it would defuel, now I can launch with 3k if I want.

 

Hmmmmm. Interesting.

 

please please more info you say you have this on your '05?? where can i get it??
