AKA Fast Frank, or Nitrous Hotdog.

His truck (05 RC/LB 4x4) was featured in Diesel Power Magazine by TTS as being the fastest diesel in the Western Hemisphere. It was claimed to cut 1.4's or better.

The TTS crew called me out to Fontana to race Frank. We did not line up against each other, so we had to go by best ET. I was in lanes waiting for him but he hung back.

Frank ran a supposed best of 12.0x with 3 stages of N20 at 5000lb, and I ran an 11.7 and 11.8 at 6420lb. That was a year ago, he has recently ran 11.7 on the bottle.

He was a friend until he started hanging with Cole, then he got weird and started bad mouthing everyone.

Sorry to hear about a lost friend.

Do the numbers seem odd to you? We are dealing with "windows" here, cut an alleged 1.4 60' and go 11.7. Casper cuts a 1.56 best, and goes 10.60 +/-.

In all my forum reading (taken with a grain of salt when required) this is an age old discussion, perhaps even argument. The calculators aren't that far off are they? tenth...hundreths maybe? Not 3,4,5 tenths or more. Maybe he was 1500lbs lighter than he claimed, or made 300 hp more and was baggin?

What do the numbers say to you?

deep staging will kill 60' time as will the front wheels in the air at the 60' beam.

sucks tripping the 60'er w/ your back tires.

even tire size and beam heights can have some effect on the times.

some guys even went as far as staggering the front axle so they had a bigger roll out.

My best 60's were on fuel, 10.95 (1.59) and 10.83 (1.56).

These were "soft" launches, and did not dance or spin off the line. Spinning starts about 10' after the beams.

It really depends on your traction situation. I've seen a tenth on the 60 translate anywhere from .10 seconds, to .20 seconds.

So the best we know of is mid 1.5 60's (Congrats Pat).

Surely somebody is working on a solution, enabling us to get outta the hole quicker without all the drama. :D;)

It's not science, alot of racers are doing it. We just need to adapt, tune and adjust it to a 4 wheel drive truck.

Just being stiff and stopping axle wrap is only going to get us so far, IMHO.

We can get the wheels to drive under us to... Who knows with a different converter, driveshaft and 4 link we may be able to cut 1.3 60's like a Sunday drive to the store! (Exagerated drive visual)

Run a calcumalator on that! That's scootin'

Practice is #1, and if you have the front beefed up (sleeves and Cognitos) then keep upping the launch RPM until the 60's won't fall anymore.

We cannot use 100% of our power to launch with starting at about 425rwhp. If you try, you will walk through the brakes, or the truck will dart to the left and buck like a bronco for 100 feet.

So the trick is to learn the "feel" for what the tires are doing, and "feel" the engine climb onto the charger. I seldom even look at the gauges anymore. I know what the truck is going to do before it even moves off the line.

Tires are one of the keys to very good 60's and also to prevent wheel hop. Good tires make you look like a pro. But you don't always get to pick the tires, nor do you prep the track yourself, so this is why seat time is more important than anything else. Experiment.
