Congratulation to Clint McMahan - starting 20th on the USF2000 grid and finished 7th in race 1 Nice job!:checkered:

I can't answer the Df question, but I’ve never known Jack to knowingly run a illegal car.:kiss:

Jay, I was poking fun at this year’s Runoff’s tech inspections on Jack Walbran’s car. They disallowed his qualy times based on the bodywork being higher than the tire diameter.

May get a chance to run the July 4th race at Mid Ohio and have never been to the track. Would appreciate a link to some in car video. Preferably in a F600 or F500. Other links may be useful as well....

Never took it as an insult or personal attack, what you wrote was true!:kiss: And you better have the new nose ready for me at VIR.:D

This statement needs some clarification – but first a message to Leon (Mitchell Racing Services). “The bump you feel as you put the bus in reverse gear is me still under the bus”! :D Seriously,...

Pipe is mounted in the same place and I've had no issues with bearings.:thumbsup:

A conversion from 2-Stroke to MC engine is pretty straight forward. The packaging is pretty tight but makes a great race car - and fast too.

I'd ballpark the total cost at ~$17,500 minus ~$2000...

Zak, send me a PM with your phone number and a good time to call. I'll call you and talk about the class, I can talk faster than I can type! Ted

So, will the F500's get their own race now? FE only has 11 entries and they're having their own race.

In my opinion it makes no sense to combine Formula F and F500. Lap times are to close...

Hey Scott,

I have the same car (Novakar) with the same engine (2006 GSXR-600). Send PM if you'd like to talk or email me with any questions you might have. You're going to like the package once...

I’d like input on shifting from anyone using a motorcycle (MC) engine in any class.

I believe my top speed was limited by the lack of carrying enough speed through turn 10. I hit the rev limiter (15,500) a couple times during the race but not on the straight.

Where’s the best location to place the oil temp and pressure sensors? I’m currently setup with them in the output line, at the side of the engine, before the oil goes through the cooler.

The F500 and the F600 are essentially the same chassis but with different drive trains and the race at Topeka shows them to be equal in lap times. I’d be interested in your driving impression of...

Do you intend to direct air over or under the nose? Looks like over the nose which is somewhat different from your previous Novakar designs. Ted

John,

I live in Silver Spring and would be happy to discussion F500/F600 cars with you. Send a PM and we can exchange phone numbers.

Be careful what you wish for - what happens if the FV and F5 entry numbers are not sufficient for their own Group? Where will we run? Ted
