An update on the bi-wing setting: Last weekend at the Radical Cup Road America race, I noticed that many of the competitors were very trimmed out on the rear bi wing. Some 1340s were set at 3 from t...

Hi Rod, Seems Radical have designed these to be non serviceable! We take a very small ball ended Dremel type bit and machine a small cut out into the anodised metal section, next to the clip this woul...

@rlm-dan ... Thanks Dan. I was actually thinking about doing that exact 'hack' last weekend when I spent about 20 minutes trying to get something sharp under the end of the clip. (started with a jewe...

Hi Mikko, I will most likely have a used one somewhere. Do you know if it is the left or right hand oil jet cut out you require? Do you have DLC coated piston pins? Send me an e-mail - Dan@rlmracing.c...

@charleyhradicalsportscarregistry-com yes I am very well aware of how all this works. And I know it is a long shot, but was thinking that there must be people out there with broken 2.7l’s that could p...

@charleyhradicalsportscarregistry-com Hi Charley and Rich. I don't need to sell it, but I also don't want to haul it to the landfill. I picked up a Spring Mountain refreshed engine last year for $...

@charleyhradicalsportscarregistry-com thank you! I sent David a message on Robert's behalf. Much appreciated 🏁

I’m a tall and thin guy and the only trouble I had with the Radical bucket seat is that I slide in them, however tight the belts. The result is uncomfortable bruises, similar to those from my go-kart ...

@walteriv ... not sure I can help with the pin-out colours, but in case you haven't got both the wiring diagrams I've used until now, please see two different versions attached... Attachment : Rad...

Hi Dan,In addition to my engine problem, which you showed me through the data recording, I also have a "current" problem in the wiring harness.There's probably a short circuit or a broken cable somewh...

Just for completion on this one, hope Helmut does not mind me posting it, but the engine was cutting out due to a low oil pressure trip.

Race Ramps are very nice but not cheap. As others have done, I made these at 9' long that fit under the trailer door, keeping the end about 4" off the ground. $30, a saw, some screws and couple hour...

Hi Walter, Paddleshift relay would be the first thing to change. Download the Life data, check for GSP control, if this is on then the ECU is trying to activate it. This would again point towards the ...

The 13 has more initial bite but wears a little faster than the 01. They both work well.

I also had to recently do some repair work to diffuser panel. While I was at it I painted the top side a light color (silver) and clear coated it. It makes seeing and then cleanup of any leaks easie...
