Hi guys, I know that many have wondered if the Nova-Blade would ever show up with a 2 stroke. Well it has happened. The car will be delivered as a roller today to the new Nova-Blade owner.
Here are some pics

Will post a few more tonight.
494 in there now but a 493 or a 593 also fits right in there.

Are the vise-grips tunable in terms of spring rate? Are Harbor Freight models softer or stiffer than actual Vice-Grip brands?
How does that center axle support work? I assume it's used for lateral positioning, and there's obviously bearings in there, but what's keeping the bearings from sliding on the axle?
Ah, the good old CVT. I don't miss it at all.

Still room for a clutch pedal if he every changes his mind.

The best brakes on the planet. Ask Calvin. You have to look hard.

Thanks very much Brian. Please remember guys that there are couple of very important partners in building these race cars.
The first is Dave Piontek of Piontek Engineering. Dave is the genius behind all of the fab work, fixtures, machining of many bits and overall design critique.
The second is Mike Devins of Hurley Racing Products who does all the composite work including the magnificent body parts that actually fit the car and are very light too.
Here is a pic of Calvin Stewart's car. This car was and still is our development car.
We hope to start our 2nd run of new Nova-Blades very soon.

Here is your red car and the white one appears to have a similar nose and the shape will force air under the car. Why?
Well that doesn't answer the question, I see that the raised floor for the longer lower control arms need to be covered and mate to the belly pan but why not force all of the air over the body? If the area at the front edge is only rounded on the top edge, most of the air goes over instead of a portion being forced and compressed under the car.
If you're looking for a honest answer I'm almost positive it wont be posted publicly. The only way to get a answer to your question would be to show up to a event where one of these cars are at. There's not too many of these cars out there and the guys who own them aren't going to say much in response. If I had one I wouldn't either. come out to a event and hang out with us! I'm sure you'll have a ton of fun and get a lot of unanswered questions resolved.
Clint, you and I have met a few times at the races and have seen the cars in person. I've even driven one of your cars (blue one at TGPR), a red devil rotax and a KBS GSXR. I was asking Jay about a feature on his car that he markets/sells and the benefits of that feature. Not really a hard question, not even a super secret one since the nose is out there for every one to see.
Yep I remembered you, I was just saying that anyone that has one of these cars is not going to talk about it publicly. New car, new technology, means no one will talk about them in public. About the only way to get the answers is to go to a race and see them in person. I have a car that Jay built (not the nova blade) and he wouldn't tell me the answer to the very question you're asking now when i was talking to him over the phone months ago. Not being negative here but you're likely not going to get a answer unless its in person. Anytime that most anyone spends a lot of time and development on a new car they're less likely to share info open and freely. After all retaining the advantage through pressing the limits of the rules and technology is the name of the game. In order to stay ahead the technology one retains in their own design for as long as they can before someone figures it out is part of the bigger plan once the design is put into play.
Wayne,
Bernoulli's principle may be applicable in this case.
For racecar: Lift bad Downforce good....for aircraft: Lift good Downforce not so good.
That's not strictly true. It's all about managing the air as is passes under the car. The front diffuser on a sports car is a very powerful device and needs controlled air flow to work properly. It also has a bearing on what happens all the way down the car to the rear diffuser. Obviously it's a very sensitive area and sometimes if you don't have enough air flow under the nose you can end up porpoising down the road. I don't know what goes on further back under the nose on Jays car but you only have to look at any LMP 1 car to see how they manage air flow under the front splitter/diffuser You'll notice a raised center section allowing more air in to feed the splitter ramps. If you have a flat plate under the car and it touched the ground you immediately loose all downforce. When the car pops back up and air flow is re-established the same thing happens again leading to a fairly unpleasant porpoising and pitch sensitivity. When we were testing the Renault Laguna BTCC car (50% scale model) in the tunnel it had a tendency to do just that, and would even suck the rolling road belt up causing all sorts of issues!
Here's a pic of the current Ligier LMP car front diffuser for reference. With the current LMP rules, the front splitters have evolved into a hybrid wing/diffuser.

The NASCAR and tin tops with no under body air channeling don't want air under the car for two main reasons, by dropping the splitter as low as possible to the track they build a low pressure area under the nose as well as building a bigger high pressure bubble in front of the car which lowers the drag. Covering the grill supports the same goal, less air going under the car and a better high pressure area on the nose. On formula and sports car style cars, the underside of the car is part of the tuning process. When you force a given amount under the car (designed to use it) and decrease the cross sectional area after the air in under the car you increase the velocity, hence you drop the pressure compared to the air surrounding the car. If designed properly you can get down force or I should say reduce the coefficient lift of a non-winged car with minimal drag penalties even on a flat bottom car.
Many sports cars with rear wings put them low and behind the car to compliment the diffuser, increasing the low pressure area under the wing.
As mentioned, pitch sensitivity is a concern, especially when you need it, under breaking or in the turns. It becomes a challenge to get ride heights rake and spring rates optimized. Too much down force from the under body can help with cornering speeds but can rob you of top end due to the wake behind the car from the large low pressure area.
That is not Bernouli's principle, the increase in velocity gas in confined space causes a pressure drop. Easily demonstrated by holding two pieces of paper held vertically about 2" apart and blowing between them. The sheets go toward each other due to the pressure drop.
SEComposites reply is much appreciated and the only one who gave an actual answer to the question.
Wayne, I think you just answered your own question.
Dave
Actually SE Composites did. The piece of the puzzle I was missing is that when the airflow under the car gets below a certain threashold the low pressure goes away. So depending on the ride height, you might have to introduce air to maintain the airflow under the car.
