Sweet. more proof of FORD muscle over mopar going to the gym.

 

I’m assuming that by the way he worded it; these might be the street races that the police give the racers a section of street, (I’m going to assume this at least for legal purposes.)

Vic_Ferrari-
Yeah, that takes some nerves.

It's easier at the track, where you kow how long you'll have to do it, but timing it in the street races is a little trickier. Every second you pray a little harder it stays together, lol.--


As far as holding a high RMP for a launch, I really don’t see a need to, but then again, I can't afford a new trans. With my truck, with no power braking, it takes forever to hit 10 psi, but after that it hits max much quicker. I just can’t justify to myself the danger of holding it past the TC lockup RPM when my truck will go from the 10 psi to max quickly. Does anyone know how much time difference there is between holding it at the TC lockup RPM (about 10 psi for me) and holding it at 3k? I wouldn’t think it would be that much.

Now hold on =o)


Before we get crazy here, my last project was the 05-06 Cummins.
The test truck was making considerably more power (440HP, 1000 ft lbs at the tire) than a tuned stroke and it too would handle 4WD launches.

For how long? Who knows.

My point here is that the cummins engine has MUCH more power potential then the powerstroke. Anyone who needs proof only needs to spend some time on the dyno tuning each.
The powerstroke is very strong, but when you crank up the load on the dyno, it doesn't handle it nearly as well as the cummins.

The cummins "voice" barely changes under load, it just chugs along making ridiculous torque.

Now, Im not sure what Superchips released for final power numbers on the cummins, but I do know the program was toned down and tweaked for safety of a mass-market product.. I left superchips before this project was complete. Rob and Derek are INCREDIBLE when it comes to mopar, and they finished the project masterfully. I was still a "noob" with Mopar while working on this project.

Ok, went off on a tangent, lol =o)

My point here is even though they toned down the cummins tuning, it's STRONG, and there is a lot more in there. Not only this, but we proved it makes power up to 4,000 RPM when the correct mapping is found/changed properly).

A few of us gave it the nickname "Godzilla" because no amount of load from the dual eddy current dynos could stop it.
In fact, it was so strong that you could swat the throttle on the expressway at 70-80 MPH and the truck would GO SIDEWAYS!

Many times while testing the limits of the powerstroke, the dyno's eddy currents stopped it in its tracks.
However, to be fair to the powerstroke, I did log several stock trucks with only a tune at over 140 MPH, and this is on the street =o)
The top speed limiter on the Cummins was pretty elusive, but they may have found it by now.

Theres no doubt I'm a Ford guy and the Ford has a better tranny in their diesel truck, but look out for Dodge, because the Cummins 600 is better than any engine they have previously released, and they have made drastic improvements to the transmission.

I've always said this and it still holds true:
If I could have the best of all worlds, I'll take a Ford truck with the Cummins engine and an Allison trans. What a truck that would be =o)
