Where I used to live, the AutoX we would get 8-10 runs in a day. Unfortunately, they haven't been able to get a venue for the last 2 years and I moved a little ways away. I went to an AutoX over in Bremerton and only got 3 runs in in the morning and signed up for Time Only in the afternoon. Drove a long ways for a little over 5 minutes of seat time. Been doing track days and I am hooked. Way more seat time and I am learning leaps and bounds more about car control.

His was a bit briefer though: "drive to and from the track on the track pads and it should grind the existing transfer layer off going both ways." Also, on the tire pressure debate... Tire manufacturer's have tire pressure recommendations for "hot" temperatures. I played around with tire pressures on my car for a few track days but have settled on a typical pressure that feels good for me and lands in the tire manufacturer spec (where I expect it to anyway) after getting up to temperature on track. nollij fucked around with this message at 06:23 on Oct 6, 2013 |

Pretty much this. Not worth a ferry ride and a couple hours each way for the amount of seat time on such an awful surface. Now I do solely track days with NASA. Looks like they got the environmental permit approved to build the track over there though. Would be nice to have 5 available tracks in the northwest (6 if you count Mission in BC).

I need new tires: I keep looking and asking around about tires that will survive on track and have >=200UTQG treadwear. So far, I just keep getting "blah is great for AutoX! Get those!" while neglecting that "blah" greases up like bacon when they get some track heat in them. Currently, I am asking Tire Rack if they have the 255/35/18 RS-3 in the new 200UTQG. Next option may be to call up Summit Racing and see if they have the new 255/35/18 NT05 size (came out 1/1/2014). Also, looking for 255/35/18 size because I am picky. nollij fucked around with this message at 08:32 on Jan 11, 2014 |

The tires that supposedly can handle track temps: RS-3s AD08s (ran these last year, greased up only a few times when I was pushing the tires inefficiently; not 200 UTQG) NT05s RE-11s (successors of RE-01s.

I've seen this argument hashed out a few times. The only intermediate solution before full cage that I am comfortable with is: roll bar, 6-pt, seats made for 6-pt and a neck restraint. I haven't decided if I want to leave the stock 3-pt seat belts in for driving on the street yet. Even the Schroth ASM solution doesn't seem to solve the issue of the belt riding up when the shoulder belts are tightened. I would imagine, you would want to keep the shoulder part moderately loose. nollij fucked around with this message at 04:07 on Feb 13, 2014 |

Any recommendations for data acquisition? I would like GPS and accelerometer information built in. Also, as many data inputs as possible would be great. I would like to have 4 for potential linear position sensors, an RPM sensor and camera syncing at the minimum. Basically, I would like the Traqmate but with more than the 4 analog data inputs.

So I am looking at my Sparco 6-pt harness sub-straps. They came from Sparco with the snap-on pre-wrapped with a D-ring. However, the way they came from Sparco does not match up with what Sparco or Schroth show as the proper way to wrap a D-ring around a snap-on connector. The D-ring is too small to fit the harness through it 4 times to match the way shown in the instructions... Is the way Sparco wrapped it from the factory incorrect? I can't imagine they would wrap it from the factory incorrectly and provide a D-ring that is not possible to wrap it correctly. But, if so, I need to find some larger D-rings to wrap it per the instructions. Here is a link to a set of Sparco instructions: http://www.google.com/url?sa=t&rct=...0,d.cGU&cad=rja

My transmission went boom :-(. By boom I mean 4th gear appears to have disintegrated. I'll see if I can get the tranny rebuilder to take damage porn pics. That's what I get for using an Evo 6-speed for 30 minute sessions with only 30 minute cooldowns between sessions. Oh well. Going to have a stronger gear set installed. I'll avoid 30 minute sessions until I get a tranny cooler. Also, rotors are crazing pretty badly. Think before I up the power (running low boost right now) and traction, i need to get my ducting/cooling sorted.

They drove it around for a day but considering they are so packed that getting the car put on the lift is like asking for Jesus to give you a hand job they probably just said "no odd noises among all the loud noises the car normally makes." I only noticed it because after driving 160 miles back from the shop I noticed oil splatter on the back of my bumper/trunk. Also, I should note that the transmission fluid is not leaking from the drain/fill plugs which was the first area I checked. I should also note, my car sat out in the weather so the APR GTC-300 wing looks like a big pile of poo poo after sitting in the weather for 3 months. The clear coat on the entire top side of the wing is hosed.

Turns out somebody, somewhere forgot to tighten down a plug on top of the transmission that does not appear to be for anything in particular. I don't know if this was the transmission shop's whoopsy or if that is where the shop tried filling the transmission from when I asked them to overfill and to fill from the reverse switch on top of the tranny. Likely the transmission shop's fault. It's a good thing I am paranoid and eye balled that poo poo or my brand new "super duper limited run gear set" would have eaten poo poo.

CCW Corsair series seems to quite popular with people who track their car. I would like an 18x11.5 or 18x12 wheel with an offset in the +32-34 range that is affordable enough to buy multiple sets without going into the poor house.

I was looking at those a while back. They look pretty nice and would fit 275s on the low side. I could fit an 11" wheel on the stock body with a high offset. The AutoX guys are running 315s for SCCA SM class. I figure the additional mechanical grip would translate well to "technical" tracks. Also, if I just plug the same formula as everyone else (275/35/18), how can I expect to do anything but lag the cars with more years of development using the standard formula? The Vorschlag Mustang got a good bit faster (couple seconds on a almost 2 minute track) when they bumped up from their 315 to 335 (or was it 345...). I just have a hard time imagining a slower lap time from a wider tire where the drawback is additional rotational mass (less of an impact for power:weight classing). Also, there a poo poo load of discontinued tires in the 305-320 range. The ones in the 275-295 range get snatched up very quickly.

Well, those too... Both of which are proportional to velocity. So, I imagine that the optimal tire size is relative to track configuration. Just finished the splitter and air dam. Canards will have to wait until after wide fenders and bumper modifications to fit with the wide fenders. Next up is the ACD pump relocate to the trunk and the oil cooler relocate to above the intercooler to accommodate 3" brake ducting.

It's like the exact thing as the Track Attack app but they haven't incorporated the ODB2 yet and they're both in Seattle. So, halfway between Track Attack/Harry's Laptimer and Traqmate. This is already a packed market to enter. If they could figure out how to combine the Tactrix software with with the telemetry and phone app logging for <$300, they could probably push out Traqmate and those lower level telemetry systems. Also, a CAN port shouldn't be hard to add and can add logging for many, many sensors with CAN I/O modules located around the vehicle.

Wrar posted:Why do anything over CAN? Especially since you acquisition rates are so much higher than it's capable of? I can see the advantage of sensor sync, but couldn't a recorder just sample the camera or at 15 or 30hz and keep the full data stream somewhere else? CAN is an easy way to pile information into a DAQ. Racecar needs 5 data points+ per corner: Rotor temp (3+) tire temps (inside, middle, outside) Shock pots and/or load cells There are more you can add (brake pressure for ABS systems). Not many DAQs support more than 10 Analog Inputs unless you want to run multiple DAQs. It is also a lot of wiring. The only thing that needs a high sampling rate (100Hz+) is the shock pot.

jamal posted:There's some thought that for swapping street to track pads and back they should be similar. The track pads will tend to scrub off all the street pad material and then deposit their own layer on the rotors, but the street pads will not be able to do the same. So if the street pad is some completely different kind of compound you can wind up with noisy brakes that don't grab very well. So for example- using the ds2500s on the street and then ds3000s or 1.11s on the track. And as far as Ferodos go, the 1.11 are newer and a better choice for the 3000s on the track, if available. Driving on the track pads cold will also scrape the track pad transfer layer off. So, drive on them on your way home and then swap back to regular pads.
