Top FFs have 115 - 120hp and F600s are under 110hp as the 600s must have inlet restrictors. That said The power to weight of an F600 is pretty close to a FF. I think that best against best they will be very close in lap times. The FF cars have somewhat more sophisticated suspensions and the F600s probably accelerate a bit harder.Quote:

Just using published magazine numbers a 600cc GSXR is around 125 hp UNRESTRICTED at the crank and the minimum weight is 875 lbs which is 7 lbs/HP. They are significantly less than this at the rear wheels with the restrictor plates.Quote:

We are about 6 - 8 weeks away for having car #1 ready. First 3 frames are going to powder coat in a week. Will be posting pics very soon.
Well, things are finally moving forward. We have 4 deposits for our 5 car production run. Chassis fixtures are completed and we have completed the first 2 frames and control arms are completed for the cars. We have finally received about 1/2 of the machined billet parts for the 5 cars and the rest should arrive this week. We will be assembling roller #1 in the next week or so and hope to have the roller at the Runoffs for show and tell.
Yes we are way behind schedule. Our build optimism was a bit too much but we are now makeing some serious headway. Here are a few pics that I can show you now, however I am still keeping lots of things under wraps.
Here you go:
Here is a pic of about 1/2 of the required billet parts for the 5 car run. We should have the rest by the end of the week. As you can see everything is weight and strength optimized. All aluminum parts are 6061T6 to 7075T6 depending on the application. Thanks to Price Machine for the superlative work.

Here are a couple of shots of the chassis: there are a couple of tubes still to put in but we are waiting for the body for clearance checking. Guess who is getting car #1?

Another chassis pic with the old man in the seat. I will be getting car #6. BTW the driver sides of the chassis has high strength Kevlar anti-intrusion panels on both sides, of course.

Here is a picture of our new optional forged aluminum brake caliper that was designed specifically to fit within our 10" wheels with an 8.0" diameter rotor. The rear rotor is significantly larger. All rotors are floating with lug drive.

If anyone has any questions just let me know.
Should I just give up now on winning if the "unnamed" driver is getting one of these???
Hell no Jim, you can win in one of these RACE CARS!
It's been a thrash getting it to this point. A long way from drivable but at least it rolls. Now it's off to Road America to be displayed in the NovaRace pit.

That is killer, Jay.

Is that the latest iteration of the Nova-Link locating that rear axle?
I was under the impression that the more sophisticated Nova-Link's "it's not a sway bar" function was important.
Does that work just as good for unloading the inside rear?
Too secret to discuss?
Thanks,
Scott
Scott,
This is the same concept but it allows larger sprockets than the previous design. It also incorporates an easier method to adjust the ride heights.

Stout frame with great suspension. Very clever ! These racers look fast just sitting there. Looking forward to seeing the body work on.
We took the Nova-Blade F600 to the Runoffs for show and tell. Tons of interest with a couple hundred viewers stopping by to ask questions etc.
Here is a picture of the Purple Frog inside the roller. I said that he would not fit but he did and pretty decent too.

Mike is a big dude and he fits.
PS: we are starting a Rotax installation in about 2 weeks.
Hey Jay, I like the shoulder clearance built into the chassis, much better than the KBS cars from back in the 90's. After one weekend in a KBS Mk5 I sold the car because of shoulder pain from constant pressure of the braces & I'm smaller with shoulders not as wide as Frog's. Also like the switch to chain drive now days, funny how we all used the cogged belts because we thought the chain couldn't handle the slight amount of twist created by the rear suspension travel! :o

I think that I am bigger than you (6'3" 270lbs) with wide shoulders and hips. I made both of my cars (F440 and later a F500) fit me. Dan McMahan has moved the down bars on several KBS cars over the years to fit wide shoulders. My new Scorpion F600 should fit you. We will be glad to rent you the Scorpion. Now you have no excuse not to buy a F600 or convert one. :)
Jim
Thanks Scott. The entire side of the car is enclosed with Kevlar anti-intrusion reinforcements. still lots of room with great protection.
Kevin Doran (Grand Am team owner and designer of the Doran F2000 car) discussing the new Nova-Blade with Jay at the Runoffs.
He likes it!
Looks nice Jay! Is the rear axle Aluminum?
The axle is 4130 chromoly steel tube centerless ground to 50mm diameter. There are aluminum tube spacers for locating the bearings.Quote:

This is a cheaper way to go fast.................you have my attention. I know this class is fairly young but how many F600's are out there? (Midwest specifically)
Rear end looks real similar to my 1000cc mini sprint (bird cages etc etc)Quote:

Does the new Nova Blade work with both F500 and F600? Are they totally separate race series, or are they combined, where some guys run a Rotax snowmobile setup, and others run the 6 speed 600cc cycle engine setup?
Do you think F600 will eventually replace F500 alltogether?

As long as there is a choice, I think that both drivetrains will continue. The 2 strokes now have a Rotax 593 (600cc) so I suspect that the new combined class will be called F600.
Jim
Yes, the Nova Blade is designed so that it can use either the MC engine or the Rotax engine.Quote:

Does the Rotax 593 run a restrictor plate to even out the playing field of the other lower cc rotax?Quote:

we are flogging 7 days a week working on 4 cars right now. We have had 2 rollers on the ground without bodywork.Quote:

Body parts are coming out of the molds. The first complete body should be on car #1 by the end of next week.
We are flogging. Here are some pics. Midsection mold prepped for part.
Mike Devins the composite wizard holding up the diffuser.
Nose just out of the molds. The flange on the bottom is part of the mold.
Looking good Jay! Now get back to work and stop goofing off on Apexspeed! :D:D:D
One more, then off to the shop.
