Got a track related question? I'll try to answer.

[Deep Six]

Having a great day at Roebling today despite it hitting 97 degrees. Ran a personal best for this car 1:22:5 but then it gets complicated. Session 3 I get the ignition coil cel 0351 although there are no outwardly noticeable issues. Came in right away to check code, erased it, let it cool off then drove around paddock with no issues. An hour later in session 4 it's back again also with no apparent misfire or power loss issues. I may swap coils 1 and 3 then retry but I am concerned that it could be related to the DI seals and maybe I should just pack up and skip tomorrows sessions??

Coil is overheating, and degrading. Swap coils with another cylinder, and it'll go away for a while.

Different car, but brought my MK6 GTI on all-season tires out to the track after a long hiatus. Drove the piss out of it. Story of the day was understeer. Corner entry, corner exit. Even with trail-braking, the car just did not want to rotate and would run wide. That said, it was fun taking a step back and lapping at 8/10ths. The car seemed better balanced under the limit, and tire wear (melt?) evened out F-R.

One interesting thing I saw - my max speed on the back straight was only 98 mph, whereas with the FR-S, I routinely hit 103 mph. The GTI should be faster, so I would guess that's all about corner exit speed leading to the straight.

Getting absolutely destroyed by a buddy of mine driving his stage 2 TT-RS on P Zero Corsas.


Slowly chasing down an S5, but did manage to get a point-by eventually.


The GTI rolls over and play dead.

Hi Mike,

I am contemplating gauges for my car and just had several questions.

1) If one were to add gauges, which gauges would you recommend and why?

2) My main focus would be an oil pressure gauge, good idea? If so, which would you recommend?

3) How about the oil temperature? I know the ECU already has this option. How accurate is the gauge on a dash or should I get something that can give me read outs from the ECU?

Thanks again!

Not sure if this is the right place for this:

I took my car to the track for the first time.
Unfortunately, I understeered in one of the tighter corners so that my front left wheel went over the curb (the red/white ones) in an area where the grass was worn away/there was a slight dip from other cars going in.

Visually, I could see no damage, but I did go over it with a bang.

Leaving the track, I noticed a slight vibration in the steering wheel when I get over 120km/h, and the vibration becomes more constant when I take right hand curves.

Does this sound like an alignment issue, or is there something more serious I should check for?

Many thanks!

You may have bent the wheel if you hit hard enough.

If so, I'll live with it... was just rolling on the stockers...
I did notice some curb rash on it...

Should I have just straightened out the wheel and gone into the curb straight on?
Unfortunately, there was also a concrete barrier in that area...

1 - Everything REALLY important is available via OBD2/ECU.

2 - All mechanical gauges work more or less the same; I don't have a specific recommendation here. Note: the Greddy oil cooler includes an adapter and bung for an oil pressure gauge.

3 - The ECU's oil temp is accurate.

Check your left front knuckle and wheel bearing. Also check to make sure the wheel/tire is balanced.

For what it's worth I read everything I need from the phone. I use DashCommand and an ELM327 wifi adapter for the obdii port. I'm working on a way to connect the phone to the display radio. If you don't have or don't want to use the radio, you can just use a good phone mount for the phone and pick a couple gauges you really want to see. Oil temp and AFR for me.

We've been using the P3Cars Ventgauge and right now we are VERY happy with it's performance for a track car. Eventually we'll go with an AIM system like the CSG guys but for a street and track car the P3 Vent Gauges can't be beat.

We've been doing a sale this month for $375 installed for our local customers but shoot us an e-mail and we'll give you the FT86 Racer Discount if you wanted us to drop ship one to you.

The nice thing about it is that it's got big numbers and it also has 2 analog inputs so you can put an oil pressure sensor in and read that as well.

I was wondering if you could take a quick look at some data for me.

This weekend I was in time trials with NASA Mid Atlantic at Summit Point Main. I ended up coming in second place in my class but I was off the pace of 1st by just about 2 seconds. Now, the guy who came in first did set a new track record, but I feel like I shouldn't be this far off the pace. I'm trying to figure out how much of this gap is due to driver skill vs car. My car (13 FR-S) has Ohlins R&T suspension, Essex AP Sprint BBK, DSS CF Driveshaft and ACT Pro Lite Clutch. Other than a tune from Delicious and a drop in K&N filter the rest of powertrain is stock and I am competing on 225/45R17 Hoosier R6's. Last week I dyno'd at 184.5whp (dynojet) and my race weight is about 2900 lbs. (driver included). The guy who came in first place drives an E36 M3 that I think dyno'd aroud 205whp and weighs a bit over 3200 lbs and he runs on 225/40R17 R6's.

Given that our power to weight ratios are very close and we are running on roughly the same tires I would not have thought that there would be such a large gap between us. Looking at the data (which my competitor kindly sent me a copy of his) to my untrained eye I seem to doing what I can to take advantage of my lighter weight by braking later and carrying more speed through most of the turns (I could improve on turn 3), but it seems to me like his car simply overpowered mine coming out of the turns. Its quite possible that I'm over driving the car by being too aggressive entering corners and compromising my exits, but I'm just not experienced enough looking at the data to be sure. I did notice that I seem to be getting a fair amount of inside wheel slip in a lot of the corners (at one point my inside rear wheel was going 10mph more than the outside in turn 9) so I'm sure thats not helping my corner exits either. I think a clutch type LSD will probably on my list of things to do for next year.

Any way, I'd really appreciate it if you could take a quick look at my data. I'm going to be up against the same driver in October at VIR and would like to give him more of a run for his money than I could at Summit.

Did you run in TTD?

Blue e36 of Marc cantor?

Yeah rumor has it that isn't a TTD car. I run against him in NE and can't get closer than 3-4 secs. Albeit my car is stock except for tires and pads.

Thanks!

I really am talking out of my ass here so take this with a pile of salt, but I would suspect that he is cornering harder and spending alot less time at neutral throttle. At the same time he is not all THAT much slower than you in the corners. Notice the gyro channel in the data, he gets alot of rotation very fast and much earlier. I am not sure but he is probably doing an aggressive slide through the corners where he is going to a lower speed but is near full throttle for much longer. In essence he is probably sacrificing some speed mid corner in order to get the car aligned in a way to use more traction from all four tires as he gets into the apex. In other words, he is probably diamonding the corners.

Also he probably has a good torque advantage since I believe that car has a straight 6 (he should be putting down AT LEAST 200 ft/lbs vs you probably doing something like 130 or 140 ft/lbs). This helps both the straight line pull and also it should help him push the tail end of the car out for diamonding the corners.
