Default Enduros

ANyone here do any of the endurance races? Do they split the cars into classes/groups like the usual regional/national races, or do they clump them all together like ALMS and Grand Am? How long are they?

I'm at a point with the car where I need to decide which route I want to go: full race engine that can spin up quick, with turbo this and nitro that, shaved this and balanced that, and can last the entire season and be a strong, yet fragile, motor, or, have one built that is just as strong, little heavier, without the high-end internals, but will be there at the end of a 2, 6, or even a 24-hour endurance race if I ever have the chance. You know, just plain reliable. If I sink a whole lot of money into a full race engine, and end up with a catastrophic failure, that'd be the end of it for me.

I have done the 24 hrs at MidO and several 2 hour enduros, with one driver change. They are a hoot. If that's your cupa tea, get a Spec Miata, or a limited prep IT car. I can't imagine running an ASedan hard for an entire enduro, but I guess there are some guys who do.

Oh...I think it'd be a blast. Like a high speed road trip...

I think an iron headed 347 would hold up quite well.

The problem is not the motor, but the rest of the car. Brakes would be an issue, although it would stand a much better chance with the new brakes.

Oh yeah, I forgot about the new brakes. With the new master cylinders, they may just actually have a chance.

To quote Lee Corso: "Not so fast my friend."

That is out for member input and not a new rule.

EDIT:I think Wheel was referring to the calipers and pads. If nothing else, the "real" calipers we run now allow us to use a substantially thicker pad up front.

Robert, if you want a fast car for doing the enduros. I have a great car for that! 96 Cobra 4.6l Sean Hyland motor, built for the Motorola Cup Series which is now the Grand AM Series,car is set up for 2-4 hour races,with quick change rotors and calipers. I ran this car in ITE for 3 years and never worked on it like I have my AS car. I have even thought of doing the enduros with it my self, but couldn't afford to race this year at all ( AS or ITE) Will sell cheap!

I was, indeed, referring to the present brakes, over the old PBRs. I don't think the M.C. rule, should it take effect, will change the longevity of the brakes.

I'm registered to do a 12 hr in a spec miata on Oct 17th. Never done
one before, and I am really excited about it.

An AS or any V8 powered car really ups the expense level of an enduro.

In a half hour national race, an AS car burns about 7 gals of gas. Assuming
a 22 gal cell, you can run about 1.5 hours before fill. So in a twelve hour
race you are going to burn about 130-140 gals of gas. Is this race gas, yikes,
there's a thousand bucks worth of gas. Are you going to run twelve hours
on one set of tires? If not, bam, there's another extra thousand plus. A
heavy, high HP car gets expensive quickly.

Well I agree, but it must be done

Someday, sooner than later, I plan on winning the 25hour at thunder hill with an AS car.

NASA rules so that allows cheap pump gas... Hoosier tires from GrandAm that last 4 to 6x what we are used to, and the track isn't horrible on brakes...

Throttle stops to get the best laptime vs. fuel mileage stops dialed in...

y'all knew I was crazy...

BTW, we did the 25hour in a Miata one year. Lost the diff (early 1.6) and an alternator, and had to do brakes once - so we were off track like 3 hrs... But this was the funnest event I have ever done. Cheap for the seat time too, but you must realize all your seat time is in one weekend. The practice/qual session was 6 hrs.

The miata did not use a drop of oil, overheat, or miss a heartbeat - and we drove the out of it... 10/10ths all the time.
