Sorry to hear about the other drivers. The HPDE I did a few weeks ago had pretty crowded run groups as well, but everyone was respectful for the most part. There was a C63 AMG that was driving very aggressively in the novice group I was in, but other than that there were no issues.

RE-71R's don't seem to be a very long-lasting option based on your feedback and what I've heard from others. Great grip, but quick-wearing.

It might just be my driving plus a heavy car, because they still look brand new on my buddy's Cayman S. Maybe he was driving smoother/easier.

Just got back from MSR Houston's LeMons race. Check our team facebook for lot's of pics. "Team Too Soon Junior"

Saturday one of us spun the car and couldn't get restarted. It required a tow back to pits, and into the penalty box. GP090110 - YouTube

Sunday one of us pass on curbing breaking a wheel and blowing a strut. We swapped on a spare wheel/tire. GP040111 - YouTube

We ended up P4 in B-Class and P11 overall.

Default Re: Carl's 05 SM Class STi - Compression, how low can you go?

It was about time for timing belt service, but figured I should get a leakdown and compression test. The car has 98k hard miles on it and is starting to seem a little down on power on straights, as lower HP cars are keeping up.

Welp, compression is in the 125-130PSI range across all 4, leakdown was in the 6%-8% area. Very even wear which is nice, but definitely tired.

Right now I've got 3 options
1. OEM Refresh, sell car for some other track thing that I cannot ever decide on
2. OEM Refresh, keep running it for track use
3. Have an engine built for track use and run something like the 71HTA or that 18G XTR with the 7cm. I'd target about 350whp and fast spooling.

Either way I am going to start running 100 octane when on track for extra protection.

If you guys have some turbo suggestions let me know. 71HTA, 18G XTR 7cm, and Dom 1.5 have been kicked around.

I'm going to go out there and say those numbers are pretty ideal considering the mileage and in no way indicate that a rebuild is necessary. Unless you're looking for an excuse to build, in which case it's definitely screwed.

6-8% leakdown is really good for the mileage, a brand new build is usually around 5%.

125-130 psi compression isn't abnormal for a STi, that's where mine was before the build (I lost head gaskets, car ran as strong as ever). Keep in mind that different compression test gauges may read differently, which is why it's important to pay more attention to the variance between cylinders than how high the numbers are.

That said, the 71HTA can't be beat for the price. Two good friends of mine have made the switch to the 71HTA and are very happy with it. One is at 365/350 on Pure Tuning's Mustang dyno on 93, the other made a little less but his tune is more conservative.

Yeah, the wear was super even which made me happy. Just seems a little on the tired side. Guess I COULD save some coin and keep running it on track.

I'd personally run it until it needs replacing, but build a motor on the side. Makes for an easy swap when the time comes with minimal downtime.

Been busy with USPSA and two LeMons races so far this year.

I do more wheel to wheel now than HPDE, so doing some crazy STi build just isn't a priority yet. I'll run the car until it needs engine work. Sunday decided to start replacing the belt and water pump. Used two company 23 camlock tools to make the process super easy.
