How are the turbine bolts doing? Nothing to worry about so far?

Where do you buy those temp gauge stickers?

 

Bolts are fine, but they only have 4 days on them. After 6 I'll call it done. Then again, I did two days at TWS where I see 6000rpm in 6th every lap.

HRP world has the Alcon stickers which are best for the brakes because they have a wider heat range. I get the Thermax strips from McMaster for everything else.

 

that's what i run too tim. only fast women i guess! lol...

 

looking bauce:

 

Inconel CHRA bolts from TiAL w/ Inco wire:
Ok, I've now done 1 day at MSR-C on the 3.1, 2 days at the TWS roval, and 2 days at Hallett, driven the roughly 1500 miles to and from the track, and the Inco bolts are still tight. They've turned gold, but they're still tight enough that no soot has built up around the little CHRA flanges, which tells me the seal is good. That's 5-track days with zero preventative maintenence, on a racecar.

TSE Biggest Brake Kit:
Holy ****. Caliper temps from a track with extremely heavy, evenly spaced braking are so much colder. Spork brakes were unmanagable at Hallett last time and are not a viable option. The TSE Corrado kit was good and made 390-440*f caliper temps according to the Alcon temp strips and I'd lightly overheat the DTC-60's. The "biggest" kit is great better in every way, caliper temps are 290*f (not a typo). Brake pad wear is awesomely low, I started with a touch less than "backing-plate width" pad material and I have roughly 2/3 of that initial width left...this track is super hard on brakes.
The only problem is that I'm now severely overheating the rear stock 1.8 brakes. My front temps were 290*f, and rears would go soft after a few laps...when I pulled off track the fluid boiled in the rear every time (a strip said 510*f on the rear, lol). I had to back-out the bias valve on the rears to the point that I could feel no rear brake, even backed out the park-brake adjusters. I just ordred the M-Tuned sport rear conversion kit and I plan to slam-in some rear brake again and crush.
I don't know a lot about brake engineering and physics and not sure how or why I'm braking so much deeper, but I'm braking remarkably close to the SM guys on the slowest part of the track. I'll spare you the estimates on comparison, but I'm really confused on how I can brake this deep, it was on par with the GT3 and TTA Vettes.
I'll have the big rears for TXMC at HHR.

 

Nice! I can appreciate some legit useful data on the brake setups and temps. Thanks for the post Hustler.

 

Aggressive street/tame race pads in the front with .75" less rotor, and race pads on my 1.8 setup in the back is what's required for a proper balance. I'm pissed I missed Orion's sport brackets in the classifieds. Was that you?

What's "hard on brakes"? My local track has one 120-60, a 120-75, a 90-60, and a ~70-50, which is apparently considered "tough" on brakes. SMs are still gliding around without using brakes though.

 

 

The TSE 11.75 setup clears 6ULs with no spacers?

 

you better be braking that deep. even with a speed difference you're on 225 nt-01's, 15x9, bigger brakes, ast's might help a little also.
so how was hallett?

 

I couldn't really get my act together and beat my personal best. I had constant diarhea and some vomiting over the entire weekend and a bout with heat exhaustion, most likely from not eating and battling illenss, but I made it through. I didn't get any faster but had enough fun that I don't care so much.

The next TXMC at HHR might be my last track day for a while. My GF is moving to Houston for the PhD, I'm trying to get down there with her, and it's probably going to mean cutting my income substantially if and when I can find work. Maybe NASA will let me work corners on Saturday to run on Sunday.

 

Ohhh, the D in that heat is a dangerous situation. As long as you had fun, you win!

That sux, but great timing. The next TxMC event isn't until Oct.! talk to dave, that's what i did at msr-c, but they were short on workers for TT since we ran the 3.1 so ymmv.

 

basically tracks that have their highest speed straights followed by the slowest hairpin, or many med. high speed straights to low speed corners in a short span put the most stress on brakes. there's a track in s. texas that has 135mph straight (in my turbo na) followed by a 35mph hairpin that's pretty hard on brakes.

 

Wo I went through 1/2q of oil over 2 days/ 3-hours and it's not in the catch can. Should I be concerned?

 

I wouldn't be overly concerned just yet. My n/a car uses a little oil over the course of a track weekend but uses none on the street. Motor runs like a top. I'm assuming some oil gets by the valve stem seals when the engine pulls a bunch of vacuum at high rpm (braking zones). Besides checking the coolant and generally looking for exterior leaks, I guess you could pull an intercooler pipe and see if that's where it went. There's only so many places for it to go.

 

Someone is stealing your oil.

Mine appears to be doing the same thing, but I think its at a slower rate.

 

My BOV is dry.

 

I used to lose a lot of oil weekly. I replaced the valve stem seals as well as a few really worn valve guides, and I have not had a problem since then. However, I do not track the car like you do.

 

If you are not blowing smoke, fouling plugs, or dripping, I would not worry too much. Lots of engines burn oil when tracked. Just keep an eye on it between sessions so it does not get too low.

 

yeah, that doesn't sound too crazy for 3 track hours on a turbo motor.
