Just curious. Those of you race how often do you:

*Repack front wheel bearings
*Repack rear wheel bearings
*Change oil
*Change trany fluid
*Replace timing belt and alternator/water pump belt
*Change coolant
*Replace hoses

[924RACR]

*Repack front wheel bearings
*Repack rear wheel bearings
Both of these once a year, unless I've had a short season (happens too often - like 3 or less weekends) or have a loose one, in which case it usually ends up getting replaced if I can't tighten it up.

*Change oil
After every race weekend, without exception

*Change trany fluid
Every year or two - the synthetics seem to last so well (I'm using Redline, would be equally happy I'm sure with Swepco) and our cars make so little power, can't be that hard on the trannies

*Replace timing belt and alternator/water pump belt
Every year. Too cheap and easy to not do so.

*Change coolant
Usually happens to be every year - coolant to park for the winter (car doesn't get heated storage) and flush and switch to water and water-wetter in the spring.

*Replace hoses
Haven't year, after putting new ones in when building the car. Probably going to be due for them some day before long here, but I carry a full spare set (along with belts and a headgasket set).

HTH... We ever gonna see you out at Waterford for the big show?

Your PM schedule is quite similar to mine.

Oh yes carry a spare set of hoses. Can't leave home with out them.

Still considering WHRRI. Need to update to a cage which I plan to do within the year. My 924 will always be slower than yours as I will keep it stock for PCA so there would be no contest on who'd be quicker. So I'd be out there just for fun.

Will be driving it to Parade.

Well, I'd almost consider laying in some carpet to run PCA Stock, but it's not worth the effort - doesn't seem like there'd be much for competition in the Stock classes - maybe if I bumped up to run with the 944's - and obviously GT would be stupid. Actually, I guess PCA doesn't allow the spherical bearings that IT does? That might be the one notable performance advantage (vs. obnoxious rules differences).

There's always plenty to be done within the stock rules, and the 924's WILL be competitive in ITB. Mid-pack ITB at Waterford is Rustangs running 1:22- 1:24's, and the 924 has no problem doing that even with a pretty stock motor.

Sphericals are allowed in PCA Stock as I have them in the front.

Next winters project is to rebuild the rear suspension. Still have a 912 that's 90% complete that needs finishing or there will be trouble in River City.

Once the cage issue is taken care will look at NASA and WHRRI. Not sure what my 924 is capable of at WHRRI. Last lap time I had was several years ago on street tires and had not switched to 4 wheel discs. Back them I was in the 1:29's. From reseach I noted that you've been 2-3 seconds faster than me at the tracks we've both raced at.

Side door bars need to be removeable as the wife won't go over them wearing a skirt when we take the car to church on Sunday.

Most of the time I am the only J class car at PCA races. There is a 69 911 that I run against in class once in awhile but I cam't keep up with him with his difference in power to weight ratio. The 911 is 350#s lighter at the same HP. Give him a run in the turns but on the straights he's gone.

If you're looking for something different Flat Rock Speedway has a rental car program for their new 4cyl American Stock class. Rental is $250 for a Saturday which includes the car rental, two practice sessions, a heat race and a feature. For the cost of a DE am giving it a try for something different.

[924RACR]

1:29's on street tires, you should be in quite decent shape with race tires (even Kumhos - I'm still running about 3-yr-old Hoosiers) and race suspension. Big thing seems to be upping the spring rate and pointing the wheels in the right direction (suspension control).

If you're going in after the rear susp - are you upping the t-bar rate? I've got 30's, but am moving to 34's this year. Obviously this requires some special shocks, Konis just can't handle it, but I've got the Bilsteins for that. Definitely well worth it, the car's so much more controlled now that we moved to the Bilsteins.

What else do you have planned for the rear susp? Hard bushings and all? Seems to me that getting rid of the rubber on the trailing arms is key. But the RE spherical inserts are pricey; if Mark can get them from Bugpack in plastic, that'd be the way to go. I am using the RE sphericals, FWIW. I think plastic/delrin gets you 90% of the performance anyway.

Naturally I'd expect you're also doing t-bar bushings and the end mounts for the t-bar carrier (yours is a 78, right?).

I don't think the 4-wheel discs make a noticeable difference at Waterford, may even be slower due to rotational inertia. You just don't go fast enough to need that much brake - though the comfort of the strong brake pedal can't be underestimated. I certainly do like them at Mid-O.

If Mark has them at the time will consider his. Like buying from people who support the 924 and the hobby???

No, the Gayboon Grey beast is an 82.

Will probably leave the rear rate stock. Remember this is a street car also.
Doing what Dr. Porsche intended for his cars, drive them on the street and race them on the track.

Hey guys,

I ran a PCA drivers Ed at Waterford a couple years ago. My laps were in the low 1:25's with my completely stock (setup for E-stock SCCA autocross events) 1985/2 944 with Kumho Victoracers. Seemed kind of fast until I remembered my best lap in the Formula 500 car I used to drive there was a low 1:12!

What kind of lap times does an ITS 944 run?

I hope to get my E-stock 924S out for a track day this year. I'm still warming up from the autocross school the SCCA had on sunday - Too much Snow!!!

Sounds like fun guys!

[924RACR]

Comin' out to join the party??

The ITS lap record for Waterford is 1:16.6 (don't know how Bruce pulled that one out of his a$$). ITB lap record is 1:18.8.

More typical ITS pole times are in the 18's, and 944's are capable of at least 19's if not 18's at Waterford, fully prepped and driven to the limit. Not to say that you will manage that. I've managed 1:20's already myself.

You may also be interested to check out the GTS Challenge, if I haven't mentioned it already - another excellent (if not better) fit for your 924S:
