NHRA National Time Trials Phoenix 1-28-07. Doug Kalitta warming up his Top
Fuel Nitromethan powered car at the Firebird raceway in Phoenix, AZ during
the National time trials. I had to go to get my fix of Nitro cars. Check
out the sound on this one, lol.
Home made 4-cam hemi fire up #2
This fire up was to test the clutch. The idea is that you set the clutch to
slip at a certain RPM, not only so it will not spin the tires at the hit,
but so you can control the car to get it into reverse after the burn out
and stage the car. You want to have just enough drag to where if your hand
is off the brake the car will creep, but not so much that the brakes won't
hold the car. You also want to be able to bring the RPMs to the point where
the motor runs clean so when you hit it the motor picks right up instantly
rather than having to catch up with the volume of fuel you're dumping in
there; or worse, gag and die on the line because you're dumping more fuel
in than it's ready to handle.
Tommy was told to set it up so it will launch at 3000 rpm, so that's what I
was zinging it up to in this video. It's kinda eerie. The car starts
shaking and really changing tune. You can see Tommy come over and depress
the clutch pedal, lock it, and then try to get the clutch to slip by using
the handbrake... which if you notice, the tires aren't slowing down and
smoke is just pouring out of the brakes.
We also found on this run that the tach in the car is off by 100%. I was
twisting it at 3000 according to the temporary tach in the seat, and the
one on the control panel was bouncing around 6000. No wonder we hurt the
motor last time out at the track. Tommy launched it at what he thought was
2500 RPM and it was obviously more like 1250, so that explains why the
motor hydraulicked and hurt the bottom end.
Back to the drawing board. We made some adjustments to the clutch and tried
it again with much better results. but a 3000 launch rpm just seems awfully
He ended up making a few phone calls and the Skuza's told him to set it up
to launch at 2200 RPM. Much better on my nerves at least! I can't imagine
having to do this on a 90% load of nitro... I'd better have my life
insurance paid up. So we'll try it again tomorrow.
BTW- the truck tires on the back are just to be able to get it to fit into
the trailer, obviously when we're at the track we have full size slicks on

my custom build twin engine rc monster truck
Here is my first really big project.(before I build my real dune buggy)
Its a custom build twin engine monster truck, totally made from the highest
quality 7075 aluminum. powered by two XTM 24-7 pro engines (over 2,5 hp
each). The acceleration is sick as you can see in this video. I built it
2003-2004 when I was 16 years old. Total cost 30 000 SEK or $4000
Time Traveler - Nitro Funny Car Start-up
This is a Nitro fuel funny car that was at the GoodGuys show that they
started up. When the car switches to nitro it's pumping out 6000HP!! It was
really, REALLY loud! A total rush.
