Hi Don (@speedstarincdjb), How is this progressing? Any updates?

@helmutweber, sorry I don’t know what the price is. You would have to check with your Radical dealer.

Radical has been studying the gear wear issues in the SR3 Gear Drive Unit (GDU) and released an upgrade kit to help resolve the issues. Take a look at it and make sure to upgrade your GDU at the next...

Any Radical dealer should be able to order these for you.

@speedstarincdjb, Yesterday after I emailed you I reached out to one of my friends that is an expert on these early cars to get his advice. He said that he doubts that this is an ECU issue (and I agr...

Hi @nautoncall, I can add a little bit to David's excellent response. The Life Racing ECU has a battery that only gets recharged when the engine is running. People often mistakenly assume that if the...

Hi @nautoncall, As you mentioned the first RXC's came with a 3.7L Ford engine. Unfortunately the engine was a little underpowered for the car so Radical offered the 2.7L, 2.9L, and 3.0L V8 options be...

Welcome Nick (@nickallitt), Congratulations on getting your new Prosport! Unfortunately I cant help with your ratio questions but hopefully others will chime in.

@speedsmith, Congratulations on the new car! There are several ways to tackle this but your approach looks pretty good. Many shops fabricate a "C" shaped piece of metal and bolt it to the pedal vert...

@kskins1, Hi Kevin, He has 5 engines so the prices a little different for each one. He is asking ~$15k each and is willing to take engines in on trade (up to ~$5k). The cost of a new Radical 1500 is...

If anyone is interested in picking up a “lightly used” 1500cc engine give Robert Burgess a call at Radical Canada East. He has several available at reasonable prices.

@frank, have you reached out to Geartronics in the UK? They make a very good system that should work well on your car. I don't know the current configuration of the paddle shift system on your car, ...

It looks like you have a stock Suzuki ECU and throttle bodies. Here is a picture of a K7 in an SR3 that used Suzuki throttle bodies that shows how it connected to the air box. Can you tell if the vel...

@goggles, Most of the work I did to it was to refresh it so it was ready to go on the track again. It needed a new fuel cell, a rebuild of the Paddle shift system and brakes. The next owner was the...

Hi Frank (@goggles), Your car originally came with a Kawasaki 1000cc engine so the air box that you have is likely from that engine. The owner you got this car from changed the engine over to a Hayab...
