I've spent a good deal of time behind the wheel of others Evo at a few different tracks, but they were all moded and had the A/F leaned out and were making plenty more than stock hp. Never noticed any big exhuast smoke of any color, might have been due to tuning. I wonder if that led to better gas mileage as well. maybe an extra 1mpg? I estimated about 5-7 mpg when running their cars, but that depends on the tracks a lot as well, big long straights can drop that quickly.

 

I didn't notice any fuel starvation. I ran a heat on the track and half of it was with the fuel light on. I kept waiting for it to die but it never did. Interesting that you got those problems, but then again you were achieving much faster times than I was.
Maybe my Works reflash saved me an extra mpg~ I achieved a 6 mpg average

 

Well, no fuel starvation, the brakes faded away during the last session on saturday, the tire were way better than I expected, and I was running 1:28's and 1:29's.

They put me in D since it was my first time, and I never got passed the entire weekend. I'm pretty sure I was the fastest in my group that included several M3's, and M5, a couple of 911, and S4 and some other slower cars. The Evo was very predictable, and even a lot of fun going (jumping?) over the curbs on the track out of turn 8 (CincyEvo will know what I mean!). As for mileage, I averaged 8 mpg with a couple of foot and a half long flames out the tailpipe between the 3-4 shift on the front straight!

Good times, can't wait til next year.

 

A common problem with people new to road tracking is being on the brakes too long. The best way to use the brakes on a track is fast and hard. This puts the minimum amount of heat into the pads/rotors/calipers. The worst thing you can do is put the brakes on a bit in preparation to harder braking (kind of like riding the clutch before pushing it in). This puts heat into the pads and rotors without any useful purpose. Even medium pressure (versus braking hard) can cause problems. If you want to be cautious in your braking in approaching a turn, the best approach is to brake hard to slow some, let off the brake completely, then brake hard again to the proper turn-in speed.

Could this have been a factor in your fade issues?

 

A big help to combat understeer is to add a rear strut tower brace, put stiffer springs (preferably some good coilovers) and maybe even bigger rear anti-roll bars. Obviously you'll want to do each step and evaluate them, but those work. I put the strut bar in and it still understeers more than I like. Next are the coilovers. If that doesn't help, I will get the larger Cusco rear anti-roll bar. If that's too much, then I'll add the larger front anti-roll bar. I think once the car is stiffer, it will rotate nicely. Also, I didn't get any lift-throttle oversteer. I used to have an S2K, so I know about lift-throttle issues...

Good luck - I think you'll be happy.

Sounds like a great time. It's interesting that you had brake fade there & I had none & you got 8 mpg & I got 4-5 mpg. When a famous race driver was asked how he beat his competitors, he said: "more gas, less brake". Since my car was turning slightly faster times than yours, 1'24"-1'25", perhaps that's the explanation for both phenomonen.

As to curing understeer: people thinking abot upgrading their suspensions should talk to Kumar Viswalingam at Predator Motorsport (www.predatormotorsport.com). He is a shock engineer/team leader for KYB and, in that capacity, did a lot of the work on the Evo suspension, getting it ready for the US. He still works for KYB in Indianapolis and runs Predator on the side.

 

Hell yeah! You guys are making me look bad. 1:28 and 1:29...sweet! What tire pressures were you using? Next year I'll probably be able to get those times. As long as I won't have that wuss *** instructor with me holding me back.

 

Absolutely. I was trying to go harder into turn 1, but ended up braking harder to get down the the same (slow) entry speed. I was slow going into 2 as well. 3 laps of trying that cooked the fluid. I could have probably picked up a second just in those two turns.


I would agree here as well, mostly. My car is leaned out a bit with the e-manage (11.7:1 AFR) so that may have something to do with the mpg. I was coasting a bit into 1,5, and 7, but after the brake fade on Saturday I wasn't trusting them 100% either. With some new pads and fluid, next time should be much quicker.


The times aren't as fast as I was hoping for, but for my first time I'm happy. Tire pressures hot were 41 front and 37 rear. As you get more seat time your lap time will drop too. I had an EXCELLENT instructor which helped quite a bit. He barely said a word to me on Sunday, which means few mistakes.

 

I dont think there is a difference in paint... ive seen a few of my customers turn their calipers burgundy on their porsches from extreme heat.

I expected mine to do the same. I even took them to a pretty bad level of fade due to heat, but they're still bright red.

 

Mine are still bright red, but the other Evo there had dark burgundy calipers, and the white lettering turned yellow. Ick.

 

Mine are still bright red, aftrer I clean the brake dust off. My front wheel driver's side got so hot the centercap melted & fell out.

 

We had center caps *SHOOT* off after coming off the track at TMS! We ust came off and were doing some slow cruising to cool the brakes and we heard a pachuuuuuooo and then heard a slight tink tink tink. we looked at each other and were like what was that!!? Afterwards driving back we saw the cap stopped and picked it up and then when we got back in the garage saw it was the center cap... about a minute later the passanger front cap shot out in the garage... only made it about 6 feet from tha car..

 

that's hilarious!!

 

I was also getting fuel starvations at about 1/8th tank and getting the good size cloud of smoke on shifts.
