phr mustang II pulled .99g????

[one+g]

Just picked up latest phr mag and it has a blue mustang II with modified factory suspension and like 225 rear tires but all out race tires. I can look back and get the exact details but this seems alittle far fetched to me. I mean an Iroc pulling .90 and this car with less advantageous design ( but race tires pulling .99 avg.? Anyone read this? What do you think? Any of the modified cars on here put a g- meter in and tested their rides?

I have actually been on the track with Alcino, talented driver with a good combo. Yes, he pulls serious skid pad numbers, remembers that skid pad numbers do not translate automatically to a well balanced/great handling car. Also remember we are talking about a 2,000 pound with small block and race tires.

That Mustang is a really nice intelligent combination of speed and handling. I beleive this proves that using your brain to develop a good combination is much more important than the size of your wallet. :hail:

Fastest times through our cones as well :)

Besides.. we have witnesses.. lol. One of them was Mark from Lateral Dynamics. His tires are DOT legal but sticky as hell. Car felt very predictable and reacted very well.

As for the skid pad we ran several clockwise and counterclockwise then averaged the best in each direction.

Why do people think that you HAVE to spend a fortune to build a great handling car? It was fun watching the little Mustang smack around all the high dollar cars that day. About the only place it needed real improvement in was braking.

Oh, we tried like hell to get 1g but just couldn't get it to average that way. With some suspension tuning we felt it could have gotten there.

It's nice to see a Mustang II get some respect too! :thumbsup: And also that averege Joe can get his car in a magazine. Good job!

Just hard for me to imagine this car pulling similar skid numbers as a 96 lt4 vette with 315 rears. Maybe, I want try to reengineer a chassis completely

I was there to when they did the test, we were with the 65 Mustang that is in the May isuse. Alcino's car works killer, he running Hooser autocross tires that stick like glue. Also Nick, the test driver, tried real hard to break a "G".

Tires can make your car a super hero too. That’s what I learned when I was getting may azz beat in autoX by fully stock cars. Rules allow any tire that is DOT legal. So everyone runs the hoosiers and kumhos, heat cycled and shaved. Once I bought my tires I dropped my time 6 seconds on a ~55 sec course and was staying up with M3s C5s and miatas.

For the record the tires are toyo Ra1 full thread depth road race tires( not shaved or heat cycled). I bought them cause they supposedly can last 10-15,000 miles of wear. Thus allowing me to only have one set of tires. They are not the best for autoXing or drag racing, but have been great all around.

Here are some low quality vids of that testing day(kinda boring though)

Welcome Alcino. :thumbsup: I didn't realize you were a member here.

I'd sure like to hear more about the RA1's. How many miles do you have with them? How would you compare them to a Nitto 555R or Nitto 555RII?

[one+g]

Have you run withand without the tires. How much lateral g do you think they are worth? .05 ? Regardless, your car gives me more hope of cornering on a budget.

Yep, I was there too, and the car worked extremely well on the skid pad, cones, strip, and did pretty darned good in braking too. And yes, it is hard for some folks to believe, in fact I think Al didn't even believe it for a few days himself! Some of the other virtues that make it such a terrific car in these tests, other than the tires and the very light weight, is the overall aspect ratio of the car. It has a short/modest wheelbase, and is relatively wide, so inherently it has a relatively small weight transfer in cornering. The car rotated perfectly through the cones, it was set up exactly right for that test in particular. I won't ever forget the test driver's responses after he laid down some fast cone sessions, he was blown away by how fast and easy to drive the car was.

And yes, r-compound tires really "do" make a very big difference.

I've been a member for sometime. Only reading though. I like that it's more go than show here, just felt I never had anything good enough to contribute.

On with some info. I don't know about the Nittos, but Im sure they are similar. This is my first pair of R compunds. A buddy had the RA1s on his car and after a ride I needed no convincing on what tire I wanted. I have about 8,000 miles on them with 3 open track days, dozen or so autoX and drag racing events. The backs look really good. I think they have at least another 8,000 or more in them. The fronts seem to get the brunt of the abuse. With close to 2 degrees of static camber the inside is showing wear from the mileage and after a track day the outside shoulder really gets hammered. I will be happy if I get 3,000 more miles out of them. Since I run 15 inch wheels the prices are realatively cheap at $130 a tire.

I don't know how much the tires were worth in the skid pad, but the testers did say that if people want good numbers they need good tires. If you see the current issue of PHR (May 2006) Tate Walthall's 65 mustang, which was there that day, only got a .88g with a very nice suspension setup on street tires. Maybe someone could lend me street tires and PHR could do a retest. I'm sure Toyo would love the press.

Or better yet, I'll run mine with the street tires and then Toyo can give me a set of R1's and I'll re-run the course for before and aft comparison...only because I'm such a generous guy that I'd give my time and abuse my ride like that.
