View Full Version : Time for a motor swap

09-21-2010, 07:32 PM
My wife and I went to another NHRA race this past weekend in Charlotte. She took me once for my birthday but now she is hooked on the top fuel cars. I told her that maybe with a sawzall and some duct tape I could fit one of the 8000 HP engines in my boat. Of course I would have to get a taller ski pole or add a tower!

Every guy needs to see one of these go down the track before they die. It sounds cool on TV, but you need to "FEEL" it to believe it. I know it's not funny (yes it is :D) but you always see a few kids start crying the first time the top fuel cars shake the stands.

Love the NHRA top fuelers and funny cars! They are coming to Maple Grove next month, hopefully I can fit it into the schedule somehow.

I've been to the Gator Nationals many times. The thunder of the Top Fuel cars is awesome! Look forward to seeing pics of your "Motor Swap"! :D

OBTW - You might need a bigger PROP!!! :rolleyes:

And you'd have to rebuild the engine after every pass through the course...

My wife only likes to go because she has the hots for Tony Schumacher.:rolleyes:
He is a good driver and I do like the paint scheme on the car.
I won't go again in the summer. It was 95 degrees in the stands and I was thinking about being at the lake the whole day. I don't want to see any one get hurt, but they didn't even have so much as a blower explosion the whole day.

We may go back to Charlotte next spring because they will run 4 cars at a time.

How much is Nitro a gallon?:D

Good point! 8p

I think its more funny when they fire them up in the pits and all the people up front who don't know what their in for start crying from the exaust and running to the back..

I've been quite a few times. Ain't nothing like it for sure

Here are some unverified facts about dragsters from an email that has been circulating around:

* One Top Fuel dragster 500 cubic-inch Hemi engine makes
more horsepower than the first 4 rows at the Daytona 500.

* Under full throttle, a dragster engine consumes 11.2
gallons of nitro methane per second; a fully loaded 747 consumes jet
fuel at the same rate with 25% less energy being produced.

* A stock Dodge Hemi V8 engine cannot produce enough
power to merely drive the dragster's supercharger.

* With 3000 CFM of air being rammed in by the
supercharger on overdrive, the fuel mixture is compressed into a
near-solid form before ignition. Cylinders run on the verge of
hydraulic lock at full

* At the stoichiometric 1.7:1 air/fuel mixture for nitro
methane the flame front temperature measures 7050 degrees F.

* Nitro methane burns yellow. The spectacular white
flame seen above the stacks at night is raw burning hydrogen,
dissociated from atmospheric water vapor by the searing exhaust gases.

* Dual magnetos supply 44 amps to each spark plug. This
is the output of an arc welder in each cylinder.

* Spark plug electrodes are totally consumed during a
pass. After 1/2 way, the engine is dieseling from compression plus the
glow of exhaust valves at 1400 degrees F. The engine can only be shut
down by
cutting the fuel flow.

* If spark momentarily fails early in the run, unburned
nitro builds up in the affected cylinders and then explodes with
sufficient force to blow cylinder heads off the block in pieces or split
the block in half.

* Dragsters reach over 300 MPH before you have completed
reading this sentence.

* In order to exceed 300 MPH in 4.5 seconds, dragsters
must accelerate an average of over 4 G's. In order to reach 200 MPH
well before half-track, the launch acceleration approaches 8 G's.

* Top Fuel engines turn approximately 540 revolutions
from light to light!

* Including the burnout, the engine must only survive
900 revolutions under load.

* The redline is actually quite high at 9500 RPM.

* THE BOTTOM LINE: Assuming all the equipment is paid
off, the crew worked for free, & for once, NOTHING BLOWS UP, each run
costs an estimated $1,000 per second.

The current Top Fuel dragster elapsed time record is 4.441
seconds for the quarter-mile (10/05/03, Tony Schumacher). The top speed
record is 333.00 MPH (533 km/h) as measured over the last 66' of the run
(09/28/03, Doug Kalitta).

Putting this all into perspective:

You are driving the average $140,000 Lingenfelter twin-turbo powered Corvette Z06. Over a mile up the road, a Top Fuel dragster is staged & ready to launch down a quarter-mile strip as you pass. You have the advantage of a flying start. You run the 'Vette hard up through the gears and blast across the starting line & pass the dragster at an honest 200 MPH. The 'tree' goes green for both of you at that moment.

The dragster launches & starts after you. You keep your foot down hard, but you hear an incredibly brutal whine that sears your eardrums & within 3 seconds the dragster catches & passes you. He beats you to the finish line, a quarter-mile away from where you just passed him. Think about it - from a standing start, the dragster had spotted you 200 MPH & not only caught, but nearly blasted you off the road when he passed you within a mere 1320 foot long race!

Looks like I'll be going to Gateway next year....good stuff there^^^

I happen to meet a guy who has a friend in the crew for Jeff Diehl. He said that he can get me into the pit next spring at Charlotte, and that a lot of the information in the email about the top fuel engines is slightly exaggerated. For instance, he has several spark plugs out of Jeff's car and they look like typical spark plugs...not melted down. Just to show you how much HP these engines are pushing, check out the video of Jeff's car when one of the headers comes off. At around 2:10 it's in super slow motion....looks awesome.

I was at Charlotte at the end of the video when his body blew off. If you look real close you can see me waving in the stands!:D
