People are not impressed when I say my car makes 200 RWHP, but they are more impressed (and confused) when I tell them the car runs low 14s.

Lou, remember when we put my 3200 Cuda on the dyno at Pittsburg?
204 rwhp, then ran 13.5's an hour later, under exactly the same weather conditions as the dyno.

How much flywheel HP did the Cuda make? Just curious of what percentage of loss through the power train.
Thanks Derek

It is just over 20% loss with a 904 and <3000 stall converter, according to Cameron Tilley's testing (engine and chassis dynos). Manual trans is probably more like 12-15% loss.

The cool thing about Charlie's dyno pull (nitrous) is that the HP curve was dead flat from 2500 - 6000+RPM. Yes, you read that right. The torque started way high (400 ft-lbs??) and dropped linearly through the pull. So, his peak HP was the same as his average HP, whereas most engines have a pronounced HP peak at higher RPM.

The Slantkota engine has made up to about 220 average flywheel HP on the dragstrip (by a calculator and trap speed), and the 64 Dart about 260 flywh HP, and the turbo '68 Dart just over 300 flywh HP, but those are average numbers and the peaks will be higher.

That's the double edge sword to nitrous, instant torque. Can be good for acceleration, can be bad for parts longevity.

I have seen many Procharged cars on the dyno. The torque is flat on them too.

yep I have The frames Tied.. I am also looking at lightening the K member as well - An alton type front end would cost me ~$2-4K If can keep the intergerity of the k frame while cutting some of it out and replacing it with tube or channel I would be delighted :-)

Car's metal was already thin enough from the Salt water mix from being on pittsburgh roads 1968-2003.

Acid could be scary :-0

That's AWESOME! What was your starting weight again?

Your dedication to "looking in 1600 places and removing an ounce" has certainly paid off!

I hope to copy some of your techniques on the Duster at some point.

Are you doing car weight with driver or just car weight?I normally weigh 185lbs,went on diet before I went for A gas record,got down to 170lbs.I will diet again just before Vegas,,alot easier for me to lose 10-15 lbs than to get it out of car.My lowest weight with me in the car with 2 gal of gas was 2336 with me weighing around 175 lbs.Nitrious system is gonna add about 40lbs so thats why I am wacking more and will bee on a diet before Vegas.Mark

Hi Mark, That Figure is with Me out of the car - My race ready weight is 222# with jacket, Helmet, and gear, etc.

@Rob Simmons - at the end of last Year Before I Began any cutting etc The car was 2595..


Today I was able to hack out 4# of stuff from the Passenger Door, and the Passenger Fender, and From the "Spotweld Seam" around the Front Passenger Door - I am going to cut the "Spotweld Seam" area out of all 4 doors and I am going to cut the rear doors off the car - hopefully remove `~20# from them and then weld them back on. I also have some aero Ideas for in front of the rear tires and To get the Sides of the car low to the ground.

Calculated Weight today -4# = 2243.5 I did add weld to the Seams where I cut off the Spotweld areas, but most of that got ground away flat :-)

26 Pics of th progress:

In These Pics I am Cutting the Top of the fender to raise it to match the angle of the Raised hood in the back.. AKA AERO FENDERS!

Image


Image


Image


Image

Here I am Welding the Seam on the fender Back together a bit to add some rigidity.
Image

More Boogery Weld goodness - I will grind it smooooth!
Image

Welding on seam complete
Image


Image

Every weld has to get the obligatory coat of black - Either satin gloss or flat - This time it's flat.
Image

Adding A Piece of.025" AL sheet to fill the Gap for the AERO FENDER
Image


Image


Image

Cutting Some More weight From The Passenger door - Hope I dont get caught in any wind storms!
Image


Image


Image

Lots Lighter Now!
Image

This Is the original Look of this area with the Pinch/spotweld area - All 4 doors have these and even under the hood has areas like this as well.
I plan for now to cut out the metal for all 4 doors and Re-weld the seams flush and then grind them smooth!
