Got it. Yes, certainly looks to score high in that category. :thumbsup:

As I posted recently there is much progress on the new Nova F600 Blade. There are multiple projects going on at the same time but here is an update on the bodywork.
The machining of the body buck is nearly finished and should be completed by tonight. Mike Devins of Hurley Racing Products is building all the body components and tooling required to make the bodies for the new F600.
http://www.hurleyracingproducts.com/index.html
This method was chosen as it will produce the most accurate body at the lowest possible cost. The body will be as close to the SolidWorks & CFD models as is possible. The basis for the buck was made from large blocks of tooling foam that were glued together to create an approximation of a block that the body would fit into. This "block" is then machined on a very large 5 axis milling machine so that the final product will be dimensionally accurate.
Mike has already posted a couple of pics but here are a few more. Mike will be posting some additional pictures and a video (if it comes out).
This is a view of the nose during the milling.

Lots of snow while machining the cockpit opening.

Just a little aero bulge to clear the front pushrod.

Really SWEET!!! I would have to agree, that's probably the fastest, most accurate way of making a plug from a Solidworks file..... Probably could use it for an investment casting...
That advance Solidworks course starts next week...... Maybe I can send you some kart bodywork for CFD analysis? :)

That looks really cool. I admire your design skills.
a couple more pictures - I will post a video after editing.
Drool.:checkered:
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
That's fantastic :) How long does a big piece like that take to cut? I imagine the feeds and speeds must be pretty satisfying!
Ted,
Look at some of the high end LeMans cars and you may see your answer. The front noses are ground effect devices, and the air moving underneath makes a little trip thru the rads on it's way out (maybe?) ;) :confused:
Both over and under as in the RakaVon Ted. It is actually very similar to the Rakavon body with a lot of minor changes as a result of the CFD I have done in the last year. The biggest visual difference in the nose is that it has the ledge in the front and the leading edge is less blunt.
Fantastic :thumbsup::thumbsup::thumbsup:
Wow, 20 hours!!!! Probably what, 5 times that by hand? I'm sure know better, but from what I've been told by a buddy that does smaller foam machining, you can't machine it too fast or the tool bit gets hot and melts the foam. That being said, I guess the tool paths would be more efficient with a 5 axis. Did you flip it on it's side and index it to do some machining?
Jay looking at George's RAKOVAN, I can see some of the changes in the nose, slightly less blunt where it goes over the wheels. I bet the older nose had a big red blob there on the CFD!!!

So,......
Isn't a F440/F5/F600 actually a sports racer, not a Formula car, ??? Looks like it to me.
Also, for those of us that have completely ignored those smelly annoying snowmobile powered things,
what IS the suspension configuration? Isn't there something like pushrods? but no shocks?
what is 'an elastomer springing system' and how's it work?
No. The tops of the wheel are always open, and many (most?) F500/600s have narrow noses. The "sportscar nose" is an option, not a requirement.
The F600 isn't snowmobile powered. It uses a 600cc motorcycle engine/transmission, similar to the 1000cc FB drivetrain.Quote:
Also, for those of us that have completely ignored those smelly annoying snowmobile powered things,
It can be pushrod or pullrod. The "elastomer" is a small round rubber "puck" that serves as the spring in the suspension, with the specific material unrestricted. How the puck is used is open to the designer's imagination, but they are generally used in side-to-side compression, resulting in a progressive spring rate. There are a lot of very creative approaches out there in F500/F600s that result in a wide variety of handling characteristics. Done right, these cars are a blast to drive, and roughly as fast as FF. I'd bet that a F600 without the restrictor in place would be faster than even the top FFs at most tracks.Quote:

and
9. Bodywork
All mechanical components of the car, forward of the roll cage, shall be covered by suitable bodywork. Exceptions are the wheels, brakes, front suspension components, and the cockpit
I read that to mean the suspension, like the cockpit, must be uncovered.
Dave
Several of Brian's F500 lap records from 2007 in the RaKaVon, (still records) are faster than the current FF records.
What are the relative power to weight ratios between F600 and FF? I would have thought a lighter F600 with more power and a 6 speed 'box should be faster anyway?
Using this logic, wouldn't most F1 entries from 1972-1974 with the full-width noses be sports racers?
To unravel the suspension mystery, stop on by at Blackhawk or RA and I'd be more than willing to show you the inner workings of my smelly, annoying little F5 machine; the one in which I call the best bang for cubic dollars spent in my time in racing, and that includes my coinciding time in FF. :beer:
Jacques N. Dresang
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.
A top notch F500/F600 will out accelerate a FF with no problem. I think the FF have a bit of an aero advantage with the F500/F600 body work rules requiring full side pods etc. Jay may be able to elaborate on the relative aero performance between a FF and F500/F600 better. 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.
Jay,
What is the latest update on the Blade and timeline?
Clint is ready to test drive one - as are a couple of hundred other drivers
I can just see it now at the track - with a taxi sign sitting in the pits and line of
people :) .

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?
http://i399.photobucket.com/albums/p...um/image-1.jpg
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.
http://i399.photobucket.com/albums/p...m/image-10.jpg
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 thought that you knew back then that you could move just about any bar out of your way.
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?
