If they are waiting for 30 commitments, they will never build any. The NP01 was supposedly 50K when they first came out before they became 80-90K. How many of those are around?

Re: WRL, they have created a "Spec Challenge" for us and profess to let us run at WRL weekends pretty much whenever we ask and can draw some entrants. We have done Cota twice with them and it's been a blast (plus we're done by Saturday at like 10AM) - see my "CoTA, last to first" video (YouTube Phantom9192).
If you want to run in the enduro races, I think you'll have to get special dispensation and you'd be classed in a "super" type class that doesn't compete for the overall win, etc. It's a limited set up as I recall.
I do very much miss endurance racing in this car, though. We used to have one 6 hour race per year and the occasional 24 here and there (back in the middle ages I raced in a 24 at Moroso which is now Palm Beach).

It is likely that SRF will have an opportunity to run at COTA this December with WRL 12/7.

Last I heard GRP tooling was quite expensive but maybe keeping the sections small fixes that? IIRC GRP is not really repairable so maybe they'll make their money from spares?


I think a few days with Mike Davies would do them a lot of good. It's a spec series, so why go with exotic materials? Make it fiberglass so it's 15 lbs. heavier but cheaper to run/repair. It's always the last 2% of performance that doubles the cost. Not necessary if everyone's in the same car. But I'm preaching to the choir here. :D



Mike Davies is our guy, not their guy, and that is an advantage to us. Why would we want Mike's knowledge given to them so that they can potentially take customers away from SCCA Gen3 racing?
And the LAST thing SCCA needs is more classes.

I know not to throw stones is glass houses so I will admit the SRF3 design is a bit dated, but this RUSH thing or whatever it is called does not overly excite me. It looks like a Formula 500 and a radical had a baby. Our car can sound that cool with the straight pipe...

As Scott said, good luck building any needing 30 commitments up front.

I was thinking of the Enduro's. I think people would be surprised what a car with an old escort engine could do! While we might not have the power as other cars I am sure we could hold our own. Stint length due to fuel I think prob be one of our big downsides, but I think it would be a blast!

I don’t know everything about the SR1, but I know quite a bit. I raced shifter karts with DAMZ, and during this time Dave Hosie designed and built the first prototype. It was not originally intended to compete with the SRF3, but was built as a race car that could provide a shifter kart like experience that was not as physically demanding as a kart. The prototype was built with a 600cc Suzuki and is small enough to be driven and even go wheel-to-wheel on some of the larger FIA kart tracks. In fact it has many, many laps around Speedsportz outside of Houston. It does succeed in the goal of being very fun to drive, like a shifter, but less demanding. As far as overall size, it’s close to the single seat Radicals with the 1000cc engine.
Eventually the 600 cc prototype was tested at MSR-Houston, I was present at this test. The car was run off the trailer with a basic setup and if I recall, ran two or three sessions, trouble free. The lap times were comparable to a pole time for an SRF3. Ultimately, the car may have been able to go a little quicker because these were Blair’s (the driver, Dave’s son) first laps at MSR-H and they were having problems getting enough heat in the tires. They have since changed over to our tires.
Needless to say, Blair had a blast on a full size track and Dave felt comfortable enough with the results that he felt he could safely upgrade to a 1000cc motor without being too fast. Safety is always a primary concern with Dave, and there is no-way Dave’s wife is letting him put their son in a car that she’s uncomfortable with. My opinion only is that the car will end up being about as quick as the SR3 Radical.
The NP01 still hasn’t gotten the numbers needed to be successful in NASA. In my opinion, that’s due to price. The SR1 fills that affordable purpose built spec race car void that The NP01 priced itself out of in NASA.
I know they have tubing, brakes, steering components, shocks, and hardware coming in to build 65 cars. Many of those parts are being built in-house and they will stock replacements. Orders are placed and cars will be built as soon as the materials come in. I have never heard Dave mention needing to build 30 cars at once, I don’t believe that is accurate.
I texted with Dave last week and he’s really excited about where they are and with the orders they have. He still feels comfortable with the pricing after sourcing materials, so the pricing hasn’t changed. I believe he also got the first batch of engines last week. The engines will also be spec with a program similar to ours in order to maintain parity.
I like the tire rule they have mentioned in their rules (1 set per weekend) which helps reduce costs. The paddle shifting is cool, although I like our H pattern and rowing the gears. It’s a neat car and I’m certain that I’ll get to drive the new version very soon. Once they get going, likely I’ll do an arrive and drive one weekend.
Ultimately, I think the SRF3 and SR1 could help each other due to cross shopping and sanctioning bodies. Without a doubt, NASA need something like this car and I’d like to see more purpose built race cars on track.

I ran the CoTA race with WRL as well last year, it was actually my first race in my SRF. It was a great event and I hope we get to do it again this year. Maybe we should see if they could add some more to the schedule? The practice day and qualifying with an early 50 min race was a fun format.

Seems like it is just a Formula SAE car aka FSAE. Pretty much all the aspects including how diff is placed. all the pictures with the bodywork are rendered images.

It’s nothing like a FSAE. Much more like a Radical Prosports or Radical PR6 single seater.
