Yes, 98 RON not US 98 MON.

Tires: If you're not running a new set of Michelin's each weekend, you're not ever going to win a race. Not in the classes I race in. Not unless the top 10 cars crash or blow up.

With respect to service times: I know quite a few people that have paid a big price for not sticking to the service schedule. And I know quite a few people that have not and have gotten away with it. But for those who didn't get lucky .... not good $$$

I'm sitting in Vision Motorsports as I write this and there are a stack of Cup engines getting serviced in the engine room. Glad none of them are mine :-)

On the other side of the equation... the reason I'm at Vision Motorsports now is because the GM engine shop (RPM Motors) pulled the pan to service the main and rod bearings after 2 1/2 seasons of track time. So since they are pulling the oil pan, I took the oil pan to Vision to get a couple of bungs welded in it.

Anyway... the GM engine shop called and said there's no need to replace the main or rod bearings.. The rod and main bearings look brand new. They told me not to replace them. So with that, and the leak down between 1%-3%, the only thing to replace are the valve springs.

That would never be the case with a Cup motor with that kind of time on it.

Total service cost after 2 1/2 seasons of racing: <$750 ish

That's pretty amazing and as said it's hard to beat the performance per $. But I still feel it's a bit of apples to oranges comparison. It's a more fair comparison to compare a Cup engine and maintenance schedule to a C6R engine.

So 98RON is roughly equivalent to 93MON. But 93MON is a LOT better than 91 pump gas in California.

No matter... if you can tune it for the lower octane, the engine would probably lose 15-30Hp depending on the tune..

And unless everybody tunes that fuel, nobody will. Nobody is going to be the only one to give up that power.

So yeah.... $10/gallon fuel.

It may be somewhat apples-to-oranges. The thing is, that if I ran a Cup Car... I would have to run a Cup Car engine to be competitive. But I don't run a C6R engine and never will need to in order to be competitive. So I don't need to compare it to that.

The comparison is what I'm running in terms of cost/yr vs that it would cost me to run a new (ish) Cup Car in order to compete in the top level classes of racing.

The difference/year is huge. Enough to pay for a big chunk of my car after 3 seasons of racing.

It is horrible, but I am concerned for the reasons you feel this is so.

Remember - Ethanol is 108 octane.

Love that 944 coolant reservoir...

Have you installed the brave pills yet?

Great job, looking forward to the in-car video!

Cheers,
Mike

Looking good!

Just making sure: your oil coolers have a cutout in the sheet metal to ensure air will pass through, yes?

Looking great Tony! I cannot wait to hear your feedback (and your lap times) after you have had the chance to drive that beast a few times. Looks like it will be a lot of fun (and super reliable) to race. Perfect timing to finish the car because the weather is really nice this time of year and you won't have to make your first few runs in boiling hot temps.

Woo Hoo

Got the wheels Friday... all $9k worth.

Car is out of the engine shop, and going in for wiring tomorrow.

Then back to Vision for a few more things and the BODY!

Without the wheels, we couldn't do the body work.

It's game on!

Well done Tim
