I know Jay's aero design had a lot to do with the performance of Calvin's car, but I agree with Matt and Clint that there was some power advantage too. Without data, the percentage breakdown is just...

That was won of the best races I've watched in a long time. Felt bad for Clint. Lower heim joint snapped under braking going into the bus stop. Matt put on one hell of a driving clinic. Congrats...

Nothing yet. Still trying to get settled in.

I sent a sample of Royal Purple off for analysis after 3 weekends including test days with my F600 GSXR. Report said it had plenty of life left to go the rest of the season. I change my oil once a...

LOL! We can only hope.

Dow made it official this morning and announced Anna's promotion. With that promotion comes a transfer to the Freeport, Texas facility so we will be moving by the end of summer. I hate leaving NC and...

I believe the one he is referring too is the Aeromotive 13105. I had it on my first F600 and it worked great.

It was a great weekend at VIR for the first race of the 2014 Formula 600 Challenge Series. 8 drivers took to the newly repaved Virginia International Raceway full course. Saturday started with...

Another option if you MC uses 3/8-24 banjo bolt is this.

It is in my profile. Charlotte, NC.

What about just adapting the air box to existing Novakars?

If you can find a shop that can do a hot flush on the oil cooler I'm of the opinion you can reuse it. I found a local industrial cooler shop that puts the cooler in a boiling cleaning solution while...

Thanks for the lead but I already found and purchased one.

Just got permission to release the official schedule for next years F600 Challenege Series! This is the big news I was teasing about earlier. We have teamed up with SCCA Pro for 3 of the races! More...

Most of the F600's will be running the F600 Challenger Pro Series next year. We have some really exciting things in the works for next years schedule, but can't talk about them yet until we get...

No major changes. Just some minor updates.

I'm on the hunt for a '11-'12GSXR engine for my Blade. Watching a few on Ebay, but I figured I would check and see if anyone on here had a good source for one.

Now that F600 is rolled into F500, you don't need dual certification. Your class on the side of the car for next year will be F5 even if you are running the 600 MC engines. You only needed dual...

If you understand the details and math behind suspension design you will realize there is nothing rudimentary about Jay's suspension design. He has a lot of time and money in material research to...

Yes, the chain does have to take the twist. The twist isn't an issue though. Like I said, F500's have been using chain to the rear axle with the same twist without any issues. I have 4 full...

Chain drive has been used for many years in F500 to drive the rear axle. What Jay is doing from that standpoint is nothing different. I have done the calcs for a few cars and we generally have...

Glad to see you were OK. You were flying and the speed you went off had me nervous for you.

It is a secret. Jay isn't letting the cat out of the bag until the car makes a personal appearance at it's first event. ;)

12. Good catch on that one. I'm not sure if they are renaming the class F6 since the snowmobile engine options now include a 600cc option with the Rotax 593. Might have to submit a letter to the...

As far as the definition of steel there is some vatience in the industry as far as % carbon to differentiate iron from steel, but it does have to be primarily made up of iron. Therefore an aluminum...

6. Trailer size is very dependent on what you want to bring. Some bring a small hand carried toolbox and minimal spares and fit in a small 7x'14'. Others (like me) bring a 2000 lbs rolling...

I'm drooling in anticipation! Can't wait until I picked mine up!

Looking good Jay! Now get back to work and stop goofing off on Apexspeed! :D:D:D

Sure. FS only has minimal rules for weight and wheel base if I remember correctly. As long as you meet those and have the car dual homologated to FS you would be legal. Now understand that at just...

Wow! What an incredible weekend and wrap up of the inaugural season of the F600 Challenge. Weather started out great on Thursday for the test day with about 1/2 of the field participating. Thursday...

Try hitting up your local autocross forums. I have had many an autocrosser come out and crew for me.

Dan and several helpers, Bob Clay, Jonathan Bowen (GT FSAE),
George Fox and Clint McMahan, have thrashed nights
and weekends to get this car ready for the ARRC. Seen here
is the brand new main...

I figured it was overlooked when the engine chart was made. Wasn't completely sure what wording would be removed from the current rule set when the engine chart was added so i figure we needed to...

700 lbs is for the old 440cc engine.

494 = 800 lbs
493 = 825 lbs
593 = 850 lbs
600cc MC = 875 lbs

I hope it was a typo. If not they just obsoleted every 493 and 494.

George replaced his mainly due to geometry issues trying to package it in a Novakar chassis with direct drive. It is a good engine, but it might take a car designed from scratch around it's geometry...

Not sure if anyone has contacted Yamaha. The Yamaha packing makes it tougher to fit in a F600 chassis, especially since the transmission output shaft is a fair bit higher than the Suzuki. This can...

No problem. Under the original regional rules the 599cc Kawi was legal as long as it was a road going version of the bike which it was from '07 to '12. We will have to wait for the November...

Jay is correct. Up to '06 you need to find a Kawasaki 600RR which is the 599cc version, but they were made in limited numbers for racing classes requiring 599cc displacement. In '07 to '12 they...

None of the MC makers that I know of sell a crate engine. Your only option is to buy used or the occasional parted out new bike. As long as you get the engine from a reputable supplier, a used...

November Fast track will be the updated rules.

That is why it is important to just do a single 180 degree wrap around the roll bar and then wrap the tail around the tow strap several times. I'm not for tow hooks or straps on the front of the...

It is quite easy to do if the tow driver is not paying attention. The roll bar on most formula cars is significantly biased towards the rear tires. So once you get too much of an angle on the tow...

The chief steward made us aware that starting this year SCCA now carries insurance to cover these non-racing incidents. If you have damage caused by wreckers, tow vehicles, etc. Make sure it is...

I have been asked not to discuss the details until after the insurance claim is taken care off for the flipped car. I am very disappointed with the track personnel and some of the things that...

OK, but banged up and sore. Thank god he put his helmet on. Helmet took a hit and has a large grind spot. More later when we get home. Still traveling back this morning.

Thanks! This is the 4th round of the F600 challenge. A $3000 tow fund and $1000 prize fund plus contingencies helps to get all the F600's to come race at the same track! We should have 10 F600's...

I searched for the offending thread on Apexspeed and I couldn't find it.

LOL! I had to google it too.
