Someone said they wanted to merge two Hayabusa engines together.....check it out

Bang for the buck, it's hard to beat a last-year's sorted racecar, then add power & tire and reduce weight where you can if you're not limited by rules.
As far as an older car, I like the idea of using a modern tube car and putting vintage body panels on it. Obviously wheelbase & track width of the chassis need to work with the proportions of the body, depending on how original you want it to look.

Here is how you make an old Mopar out handle that race prepped Mustang:

How to cut 4 seconds off your ET for $10

So if you cut enough of your car away you will eventually beat that Mustang and if you think of it this way, once the weight cut out of the car you should be able to get away with a 0.84" diameter torsion bar and have some excellent cornering capabilities......

I hope you know I am just kidding with that last post.

Yes, it can be done. Lots of recipes to get there, too. None of them particularly inexpensive, though.

The mustang continental spec tire is a 275/35/18. I don't know how much hp they run in that series, but I doubt it's over 600.

To beat him:
Put 335/30/18's on all 4 corners
get the center of gravity as low as possible while still maintaining a minimum travel
Ensure your suspension maintains a good contact patch in the corners
Beat his weight to power ratio across the rpm band you'll be working in
Upgrade your braking system to ensure no fade at threshold braking lap after lap

I have a similar yet lesser goal. Keep up with a C6 Z06 & a porsche GT3. I'll be running 275/35/18's on all 4, factory suspension geometry, a 3G Hemi, and 14x1.25 with viper calipers on all 4. I should be running in a few weeks and racing in a few months, so that should give you a baseline on what to improve on. Shoot, Tim's valiant and Peter's dart are both good cars to base a build off of with your goal in mind.

It depends. The basic chassis may be built pretty symetrically since Nascar imposes rules on how much offset and bias can be built into the chassis. Changing control arms and spring rates to balance the car out for right and left turns should be a simple bolt on effort if the car is a symetrical design. Actually a Nationwide or Late Model series car may also be an alternativesince they are built on slightly shorter wheelbases to different requirement levels.

For that matter, you could probably have Racefab, Alston, BMR, Howe or any other supplier put one together specifically for your requirements. Heck, Howe even offers a TA2, GTA, and GT2 chassis package if you are so inclined: http://www.howeracing.com/Adobe/HoweTA20811.pdf with a base price tag of $72.5k for an LS3. Since they will do any engine and body combo, all it takes is some more money for a change to a Hemi and a Challenger body and you should come in around the same price tag as the Mustang listed above. In the oval track chassis, they do offer symetrical or offset chassis builds in various stages of completion. Prices start at $2700 and go up from there. http://www.howeracing.com/p-7331-perimeter.aspx


If you really want to keep it mopar based and do it all yourself, there are enough reproduction parts out there that you can buy all the core pieces from an E body to reproduce the old Mopar Kit car program chassis for around $3500 and then add all the associated tubing for the cage and other structure for a few hundred more. After that, you can skin it in darn near any body you want. Run t-bars and leafs, XV L2, AlterK, or whatever suspension suits your fancy.

Here is a pic of that 1964 race prepped Imperial:

Perfect! I was about to pull the trigger on the Mustang but I will get one of those Imperials and a torch instead! You just save me $134,000...

Well I was riding my dirt bike yesterday.....

...why are you steering to the right while turning to the left?

I know, I know. Same as what Doc told Lightening in the 'Cars' movie.

There's a tube-chassis GT car with a C4 body Dzus-fastened to it in Hemmings right now for $11,900. Imagine that with a suitable vintage Mopar body on it...it'd be great with an early Valiant body - tell me it wouldn't drive the other guys nuts - but that's too narrow without flares or seriously bulged fenders & quarters.

Imagine if they would have been tracing where the center of gravity was moving around as the weight was removed from the 1964 Imperial.

The last move should have been lowering that car down some more that is one high riding go cart when they finished up with it.
