Sorry this is going on the 94 that is a dedicated puller (when it get's done)

 

For a pulling truck you want to get it pinned. A Fluidamper rep told me that a couple of pullers out of Ohio managed to spin their dampers off at 5000+ rpms thus the pin was offered.

 

Tiger Rag, PDR had 8 on their shelf. Had mine the next day...

 

sorry to hijack but what are the peformance gains from a fluidamper.

 

Did you pin yours ph4tty? Does a VP truck even need to consider this?

 

No real gain on performance but what a difference in idle, knock vibrations, etc... My engine use to shake quite a bit, now it's smooth like butter. Your internals will love you for putting one on. My factory balancer was falling apart so that's why I went to a fluid dampnr. Excellent product...

 

My sheet that came from Fluidampr claims:

5 hp and 3 ft/lbs on the Cummins
14 hp and 40 ft/lbs on the 6.0 Ford
6 hp and 18 ft/lbs on the Dmax

I bought it for smoother idle and less stress on parts and I've got a double disk clutch so I wanted to quiet that up some too. It's not on yet so I can't pass judgement yet.

 

Naw, I just want to spin to 3500 so I don't need it- so says the fluidamper rep I spoke with at fall brawl

 

Yes it does smooth things out. Do you still get the shut down chirp? Mine is gone forever

 

No chirp here...

 

That went away as soon as I got my DD. Did your's stay until the fluidamper?

 

It became an occasional thing not an every time thing with the dual disk clutch. Mr dodgediesel has an FE =P

 

Never ever had the chirp but my buddies 01' 5 speed does.

 

Yep, that was my thought too. I might tach a little higher just because it revs so quickly with the 4.10's that in drag racing it might be tough to shift quickly enough......especially if I add the squeeze........

Still, I'm thinking 3800 max for me. I'll have my F1 valve springs soon and won't worry about it holding it under 3100 any more. A vp truck won't get near 5000 to my knowledge. I think some pulling trucks running a Blue Chips box can see 4000.

 

Swap the 4.10s for a 3.31 =P At 60 you'd be at 2200 rpms, but in 5th gear I'd give you 10 mph in just 3rd =P (@ 3500)

The max rpm I've heard of on a 24v is 4200 using a hot redline box of some kind.
