What do you do between AX runs?
 

Is keeping the oil temp up around normal running temp important? With the average Solo II run lasting less than an minute and then a 10-15 minute wait, do you idle the engine or let it cool down between runs?

Rod.

Yes it is important to have the engine at normal op temp for performance runs. Albeit, I have been known to "jump" up on the highway in the morning after start up. Fine.

I would keep her running between runs.

Have fun.

Regards,

I shut it down between runs. When the other line looks like it's getting near the end, I start 'er up again. I try to get about 3-5 minutes of idling in between runs.

got ta let it warm up
 

I let it run once in grid till it get some oil temp 120 140 or so.
I let it run between runs if I need more temp. When the water cooled cars have thier hoods up and fans going full blast I just let it run and get stable engine temps. 914-4 extra oil cooler.

If you have a 914 and headers be careful how long you let the car idle. Its pretty easy to cook a number of things that have close clearences such as cables or CV joint boots depending on the header you use. I wrapped all my cables with heat resistant tape to slow the cooking proces.

Once my car is warmed up I shut it off and just idle while im off grid and in line to run.

I wrapped my pipes with some of the header wrap from JEG's. Works pretty good

I worked so hard at building mine to run cool that it takes forever to warm up:( If I can get the needle off the temp gauge peg (50C), I am fairly comfortable taking it on an easy pass. After a pass and leaving it idle in the lanes, it's up to 80C and we're ready.

Less than a minute on the course, then a fifteen minute wait? I'd be running my car all day long. Getting your car up to temp just means giving it plenty of idle time before your first run. But how do you ever put any heat into your tires?

Guess I'm spoiled. POC Short Track Series has 20 minute run sessions. I just make sure my car idles until it's a safe temp zone before the run group starts.

I let my car idle until it is up to operating temp. I let it idle up to the first run and we are usually a bit on the cold side (140-160). I let it idle while waitng for my second run which usually puts her at operating temperature (180+) and then shut her down between runs to keep under 220.

I'll let it idle 10-15 minutes before the 1st run.
Then after that, the engine really doesn't cool down that much with 15-20 min between runs (if you have that much), so I just start it back up right before I'm ready for my next run.

I don't think it's great to leave a car idling that long really.
I mean, this is when your engine is at its lowest lowest oil pressure. Do you really want to run your engine that long in those conditions?
I think this is when you really get your most elevated wear on your internal parts. Just my thoughts...

Down a couple of mojitos while idling-definitely refreshed and loosened up and warmed up for the next session.http://www.pelicanparts.com/support/smileys/wat6.gif http://www.pelicanparts.com/support/...s/beerchug.gif http://www.pelicanparts.com/support/...amingdevil.gif http://www.pelicanparts.com/support/smileys/yummie.gif http://www.pelicanparts.com/support/smileys/pint1.gif

Especially on hot Texas summer days-maybe switch to beer later in the day....:D

No comprende, Ed. For us northern folk, what's a mojito??

Rum drink....

For colder days up in Canada, why not wrap your oil tank in insulation? Or even a warmer powered by a dinky generator. In the fall up there, I'd be worried about warming me. ;)

Maybe I need a mojito!

Most effective way to elevate the engine temp of the women at your next party. :D

Here's an old pic of some Hoosier R3SO3s after driving home from an AX. I'm just lucky, I guess.:D http://forums.pelicanparts.com/uploa...1120359981.jpg

If you look at the Hoosier web site, you will find that they have Road Race and AutoX tires. I would suspect that part of the difference is the time it takes them to heat up. I would figure that AutoX tires get hot fast but will not do well if you ran them for 20 minutes without a break.

You are so right. The A compound warms up quickly and sticks real gud.
However with a co-driver and 95 degree air and the surface being VERY hot. the tires get greasy after 4 consecutive runs 7-10 minutes inbetween drivers.
S compound is the opposite takes at least one run at full tilt boogie to get them warm and then requires short intervals between runs to maintain temps.
