My thoughts on other options are: 1. Don't bother with charging for the battery, it is only being used for starting so if you charge it up every few meetings/track days it will be fine. 2. Contact Nor...

I beg your pardon -- upon close inspection the blipper tubing on my SR3 is wrapped in heat shield. It is such a snug fit that I did not notice it.

Welcome to the forum! Looks like you have covered the repair and as always Charlie has you sorted with information! The reason that you damage the starter motor during the spin is because the SR3 uses...

If you look on the underside of your car just behind where the oil tank/bell housing is you will see a small grommet that has a wire coming from it, this is your crank sensor. It is a 2 wire sensor. T...

@davidf so sorry to hear of your misfortune :-(. It sounds like the primary oil pump blade has possibly broken off the shaft that drives the scavenge pump. In my experience this could be from debris ...

An update to this story and my belief on 1500 RPE engine refresh schedule ... I took the car to the track today to let a few friends drive it. They did well, but on the third 30 minute track sessio...

Hi @agengw20, welcome to the Registry. Congratulations on your new XXR! Sorry to hear about your spin issue. SR3's are very sensitive to front / rear balance and will spin if the balance isn't righ...

The costs are equivalent. We use two sets of Hankook tires during a race event. The UK refresh may be a less expensive option, but I think that when shipping is considered it works out about the sam...

Hi Scott (@smajor6761), Welcome to the Registry! Once you send some time in a Radical it is hard to appreciated almost any other car. I am glad that Jonathan spoke up, because that is where I was go...

July 2022 with Spring Mountain Powertec America. The damage on this engine after 25 hours on-load was minimal but needed a new clutch and transmission parts. I would imagine there are many standard ...

I called the Radical engine department in the UK, and I was able to talk to I think the lead engine rebuilder as well as another engine tech. They both confirmed that the refresh schedule for the 150...

Thanks Dan and Charley for the input. I have sent an email to Spring Mountain for clarification, and I will likely send another to the factory. It would be useful to hear what they have to say, alth...

You are correct. In my ECU log book data, I have the following for on-load: On-load engine speed (rpm): 4000 On-load throttle position(%): 25.00 On-load vehicle speed (kph): 48.3

The SR3 cannot be beaten on performance vs cost! Interesting comments on hours, especially from a dealer, as I was fairly sure the factory still recommend on total running hours. Worth keeping in mind...

Performance Comparison The SR3 is a popular HPDE track day car and race car for several reasons. It has high downforce, is light weight, paddle shift, and has superb performance for the total cost ...
