Has anyone run the Silver State Classic ?

I want to build my car to run it at WOT.

I know HEAT is the ENEMY. I'm thinking single turbo (reliable) maybe a T-78 with a front mount or a large V-Mount (like the white Apex car) and coolers everywhere.

I need some ideas or better EXPERIENCE with running a 3rd gen at WOT for an extended amount of time.

How about aerodynamics that work not just for looks at 200mph?

Suspension mods?

Safty mods: Cage, Belts, and Seats with the camara mount?

Boost creep? I have an almost open exhaust on the car now 4" HKS Ti.

Um, yeah those fools in the unlimited class run 200+ mph. I'm going to have to officially say **** that and you are a crazy *** **** for even thinking about it. You don't want to end up like the Option 350z that blew out a tire @ 170+ mph...

So do you have any road racing experience???

Look at history, Lou Young (sp?) ran his FD in the Silver State Classic 4-6yrs ago. IIRC his car wasn't that modded. Stock or almost stock FDs have done well in One Lap so I don't see why you would need to mod the car significantly until your in the top class. By asking the questions you are I can tell your not ready for the top classes.

Your best option is to stay in the lower classes with a 95 or 105mph limit. Concentrate on driving.

The option 350Z was toast, I saw the pics...

I believe you need to progress through the classes anyways. You dont just show up and get approved for unlimited.
A guy in the local club, Blue, was in the 135 mph class this last one and averaged just under 135 with a high trap of 165. His car is stock except roll cage and Racing Beat cat-back.

I know I'm not ready to run unlimited.

That was not the question

I want to know what works as the car is being built now and I don't want to invest in something that will not pass spec/safty and a car that is reliable at WOT.

Thanks, Jeff

I know pistons engines that run on gas run cooler the faster and more gas you give them where as deisel is the opposite. You probably could do well stock, but I'm not sure with the functioning of rotaries but I assume some of the same concepts carry over from piston to rotary. Maybe just get some good mods for downforce and suspension. Maybe RE rear diffuser and 99 spec wing, and 99 spec lip. A nice free flowing exhaust for upper RPM pep, an all aluminum radiator and a nice Stock mount intercooler. And a blow up doll for the passenger seat. If you paint your car yellow you will go faster too. Vin diesel proved that in the first one. HEHE!

i dunno, but it'd be really hard to beat big red, that crazy '69 camaro that used to run. i have that thing on video and it's nuts! good luck to ya tho, i'd like to see a really successful fd run in that thing

I don't have anything to offer that you probably don't already know other than at 150 mph+ it isn't power you need, it's low drag.

Remember that drag squares with road speed. It's all about keeping the car "clean".

You'd be suprised what a good coat of wax can do at high speed as well. Our single engine Comanche airplane would gain a few knots just with a coat of wax

He Jeff,

You might read through this road racing thread:

There is a lot of good info there about cooling. Good luck!

the guy with the 20B from bermuda runs this....i think his username is bermuda 20b

Here is a LINK to some pics of the rally.

I still don't see any sevens

Car & Driver did an article on those races about 4 or 5 years ago. I don't have the magazine anymore, but in their pics there were a few FD's. I have no idea how modified they were since the shots were actually of all the different license plates of the various cars (they all had some interesing personalized plates).

I do see 1

Hey! That's the article.

V-mount or SMIC, FMIC will definitely hurt cooling ability

i would suggest a water injection setup, but at those speeds you'll have more than enough air to eliminate heatsoak. Im not sure how much aerodynamic aids will help a 7 because the underbody isnt flat, which renders most diffusers useless.

JeffShoots

Is this true. I would think a good wing and diffuser would help?

Good page too, lots of info.

My cousin in Arizona built a 3 rotor 3rd gen for a customer, some middle aged rich guy who was trying to get into some sort of "200+ mph club" and at 180mph the car started lifting off the ground, so the car was sent to some place in florida and then back to texas to go through a windtunnel and get the proper aero fittings, and the owner drove the car from texas to las vegas to meet up with the rest of his 200+mph club, and somewhere in between texas and vegas he hit 235mph, so it can be done with a 3rd gen. Keep in mind the rx7 is light though, so high speeds can be trouble without aero mods, the pictures were pretty cool though, you see a ferrari, porsche, lambo, ferrari, rx7, ferrari, porsche

A good functional wing would defintely help because its up in smooth air. I'll try to find pictures...but if you look at a McLaren, Enzo Ferrari, any other purpose built supercar, or a F1 car the entire bottom of the car is flat, and the diffusers run along the entire underbody. On a car like ours, since the bottom is not flat, there is turbulence underneath, and since most of the diffusers we can buy are only 18-22" in length, they do not provide enough surface to smooth the airflow out and make downforce.

teamstealth

look at this photo of the enzo. Notice how the entire underbody is smooth and sculpted to eliminate turbulence provide downforce. I might be off on the fact that the RE diffuser provides no downforce, but it will not be nearly as effective as this kind of setup.

Maybe I should run the NSX

No not the HONDA

Is fabbing some sort of underbody panel that is smooth out of the question? Wouldn't it be possible to create something to smooth the airflow so that a rear diffuser could function effectively?

He's considering going all out with a single turbo and whatnot, so why not make a top speed machine and see if you can win a class?
