Yep saves weight, adds some power, sounds good, not very expensive.

This past weekend i was talking to my brother who is thinking of an f3x gc or 4or 3. But he always says damn the v8 is just so badass. So i brought up a thought of going e46 track car or 1m coupe and he can take over the e90m.

E46 are still badass. I would have no interior too.

I still have front half interior in. Until I don't drive it on the street at all I'm holding off on the full strip down and full cage, fire supression and such. May never do it though as I like how the car is now and saving 200 lbs won't win me any hpde trophys. Possibly if I do nasa time trials in the future.

here is a video from the other day. think it includes the 1:37:36 which is fastest to date. still think there is more in it as i felt kind of sloppy this day after being off for 2 months. get to hear the new exhaust. no external mic so hard to tell but pretty loud. this is with the windshield mount and closed case.

Crazy that guy runs 1:37s out there too. He has quite a bit of racing experience. Sadly I think my exhaust may have given me a torque dip. Top end is better though. Saw higher entry speeds most places. 136 thru 1, 110 at 3, 106 at 5.

[bigjae1976]

Low end torque? What's that? You should be living at 5k RPM plus!

What's up with the cones in the middle of the track?

I primarily do, but dip down to that range in couple spots at this track.

This track is always set up as a school and has new students all the time. They have gates at some corners that I run over at times including this last weekend. Cones in my line just give opportunity to run alternate lines and stay fastish still.

I hate those bloody cones!

I thought I was supposed to use that little lever thing that sticks out of the floor by the cup holders but I can try not touching it?

blackstone report reveals my bearing appear fine and that i can wait longer to change my oil. was doing 5 track days and will stretch out to 7-8 i think.

[DiXiS 18]

My last oil sample I sent in was about 8 track days and 5000 miles. Passed with flying colors.

yeah as you saw mine was about 2000 miles and 5 track days. starting to trailer now so wont be street miles at all so should be able to go few more days. i was more happy to see that i dont have much bearing wear indicated.

That was mostly track miles. I don't daily the car, just drive to and from the track. Had one long trip from LA to Pahrump, NV but I prob would have had more track days on it if it wasn't for that. I just stick to 5k changes no matter on the amount of track days.

That seems pretty long service to me. Glad your oil comes out okay. I will gradually stretch it out once I know I can. I will have maybe 2000 miles again next time but more track days.

Cool. I am always curious how far you can push it. Everyone I ask always says something like 2000 miles or every 3 track days with no real reasoning behind it. It's good to have more real data to know what can be done. That's why I tried pushing it a bit farther then most on my last change and get some data. Here is a link to my analysis if you want to check it out:

Good to know, my builder who races, and is substantialy harder on the car than me suggested the 4 track days for oil change initially for me which seemed quick. I went with 5 which is still overkill apparently. I used to get oil changed once yearly in my e90 but that was more along the lines of you, 5000 miles and at most 10 track days. Last year I had 20.

[bigjae1976]

You are using a much better method than me. I go about 6 events. I count track days at +85 degrees ambient temp as 1.5 days.

With my results I would think your 6 days is very reasonable and you probably could get away with 6 or more regardless of the 85+ temps. What oil do you use? I know an ex-member who has some advise.

Your results are based on facts but your ideal intervals will slowly evolve. Something to keep in mind.

I probably could get more days but the cost of oil is relatively low compared to a engine rebuild. I probably don't have any more rebuilds in mine if I spin another bearing since I've already machine the journals for oversized bearings once.

I use TWS 10w-60. I'm sponsored by a BMW dealer so its an easy choice. In TX, its a pretty good year round oil and, to my satisfaction, its proven to work in 5 other cars with S54 engines that use TWS, 4 of which are still on the original engine and one finally went with 50k track miles. I don't see much benefit in using anything else.
