traction is gonna be a serious issue at the drag strip. Dude hook up little nozzle sprayers in your rear wheel wells for a traction agent. This could be a serious factor in traction and it could result in you blowing the competition away. Plus it would be oh so sneeky. I know of people who run fwd cars that have this setup on a honda and it runs 10s in the quarter with NORMAL street tires (non drag radials). I believe the chemical they use is called VHT, I think thats what its called. I also know of a muscle car guy who uses orange soda and claims it works quite well. Just remember not to use too much, and get some practice with it. You could prolly just hook up a windshield washer sprayer and do one small squirt and you will be set.

 

Hey, i was just wondering what is a normal amount of money to donate. I would like to donate, just dont want to seem like a cheap scate, since im still in college. What are some of you other guys donating?

I also agree with the exhaust setup with a cut out hole for better flow and it would be way better for emissions.

From the look of the competition, it looks like you wont have any problem wooping some ***. ESPECIALLY on the road course.

The problem with this "setup" is that VHT requires some time and temperature to "set" and get tacky; you don't just spray it on and get instant traction. If you try to run on it too early, all you'll do is spin the tires.

 

You spray it before you do your burn out. This will obviously heat up the VHT. Hey this was just a suggestion. Ive seen it done, and it works. With Street tires that are not drag radials, with that much power, getting traction in first or second gear is gonna be pretty tuff. With this setup, he should be able to get good traction in first gear.

 

As for differentials...does Quaife make one that's available through Mazdacomp?

I think given the multiple handling-based tests it would be perhaps a good idea to have a planetary gearset like the stock Torsen or Quaife as opposed to a clutch pack like the TII or Kaaz.

i didn't see one on the ATB list, i wonder why they have never made one for any of the RX7s

http://www.quaife.co.uk/index2.htm

not on the uk site either

 

Are a Torsen (a brand name) and a Quaife any different in their basic operation? They look pretty similar to me.

Yeah, they work the same. I was thinking along the lines of the Quaife (if it exists) being more beefy if the durability of the stocker is in question.

 

For the traction at the strip why not get something that retards the time or somethign similiar to what the V-8s use so they get the launch then they spray?

Is NOS allowed?

 

Yup.

We just got the Exedy twin plate clutch at the shop, waiting on water inj and tires.

Fyi, we have about $200 in the paypal account already, thanks for the contributions everyone

 

THAT'S IT!!

Someone put a sticky at the top of this forum that says

"Contribute to see the Rex win the USCC!!"

Sure you will get more money. $200 is barely one rear tire! (not including shipping)

 

Wish I could help. But like most here I aslo have an FD so money to spare for another rx7 not mine? pfffffttt ya right Im still "saven" for the last motor.

 

What I meant by "time and temperature to 'set'" is that VHT is a rubber cement compound (in really simplistic terms) that needs at least several minutes and 70 degrees F to cure on the racing surface (the pavement, not the tire) that already has a layer of rubber on it. Even if it did somehow set properly as you staged with this "setup", you'd only get the benefits of one or maybe two revolutions of the tire before it wore off. That would be what, four or five feet?

There were other factors involved that allowed these 10-sec Hondas or whatever to get traction.

 

What's wrong with RaceLogic traction control? It would help everywhere, not just at the drag strip...

 

Any additional traction early in the race makes it soo much better for you later on. So even if it helped out just a little it would be awesome.

 

Exactly. A far more effective (and not to mention, easier to install) method of gaining better traction...

 

This is definately an option, but the traction control only limits the amount of power that goes to the wheel so that they dont sit there and spin. If you go with the traction agent, it makes the tires grip better. Maybe both would work great. I bet they dont allow the Racelogic traction control though. I also bet that if steve kan is a really good track driver that he may not benifit from the traction control or even want to use it.

 

The problem is that traction agent only works if it's applied properly (see my previous posts...), and even then it's no guarantee that you'll hook up.

Traction control is able to react far quicker to pavement grip changes than any human, and will work regardless.

 

didnt PFS own this event a coupkle yrs ago with his triple rotor.....pretty much whipped *** but lost b/c of a little technacality.

 

That was a different event... a Car & Driver "tuner" challenge or something. Peter cleaned up on the roadcourse portion (at least partially due to his skill), but blew a radiator hose IIRC.

For this event, i'd spend as much time/$$ bulletproofing as i would adding capability...

 

This is info on the PFS 3-rotor car: http://www.caranddriver.com/article....&page_number=1

Chassis mods are supposedly limited to Koni shocks and some unnamed springs, a Brembo front brake kit, and Kumho Victoracers in 245/45-17 front and 275/40-17 rear.

 

Kaaz has a new differential now, more configurable than the previous version.

 

we are looking @ the new kaaz, it has more clutch packs and is supposed to be more streetable...
the aem has traction control and a 2-step, so we will try to use both of these, we have played with the 2-step and it's pretty slick....it shoots fire ***** the entire time it's on...thanks again for all of your input, and rich is the homo gay..

 

sorry i was logged in as someone else, but yes rich is the homo gay..
