Ask the Radical Factory #9 – Hi there I have 2 sr3’s with Life ECU’s (a 2009 and a 2010) that are new to me. I am unable to get ecu data off both cars, so I think it’s something I’m doing. I go thru the prompts and make up the file for the Life data for the car. The computer is properly plugged into the car, main switch on, ignition on. I go to where it says auto read, or just read, all seems to work and comes up with the download screen but then at the bottom I’m meet with a red message: > “no logged data to download happens on both cars what am I doing wrong? Aim data works fine. From Jack A. in Australia

Ask the Radical Factory #8 – Hey guys, after sustaining some minor front end damage recently, I’m looking to change my nose cone from a SR3 SS (Gen 1 – Chassis 150) over to a SR3 RS (Gen 2) shape. Will the Crash box underneath need to be changed also? And will the later nose cone line up with the other bodywork panels? Regards, James P

I gave it a couple small revs prolly up to 4 K , the dash display completely turn red at about between 2500 & 4000 Rpm.it was operating properly at idle or up to 2000 Rpm. I just shut it down to find out what is the issue. Can you advise. Thank you, Ken F

Ask the Radical Factory #6 – There’s a lot of conjecture around use of noise killing cans like Supertrapps, decibel devils, and so on. Some people say they are not good for prolonged use due to the back pressure, others say it’s fine but will cut power dramatically. Are they ok to use, and if so, for how long? Are there any you’ve tested out in the field which work, and could you recommend any? Thanks, Raj (@rojid)

Ask the Radical Factory Question #4 – Hello, I Have a new to me a 2009 sr3 (chassis #438). Two questions I have are where about in the setting range for the dampers is a good place to start for a high speed fairly smooth track (CTMP (Mosport) in Canada)? The dampers are the intrax racing with the single adjustment knob at the top car has medium Nik link bars front and rear. Second what set up difference change between the Michelin and Hankook radical tires? The car came with a set of each, and I am free to run either in the club racing that I am doing. cheers, Corey Bradburn

Ask the Factory Q#1 – I am writing to you from Japan. I work in automotive maintenance. I am working on a Radical SR4 engine that will not start. The fuel pump and ignition coil are not working either. I want to check if the engine control module is working properly. Can I have a wiring diagram for the Radical SR4 (Chassis No: SR4 00082j) Best regards, Atsushi K.

Ask Phil #14 – Hello Phil, I have a question regarding HD axles for an SR3 RS or RSX. Unfortunately, as you know, we cannot purchase any specifics parts for these axles from Radical, only complete units. Several of us have sourced the tripods to GKN, but we cannot find the specific inner CV hub that was used… Can you guide us in the right direction? Thanks in advance for your assistance. David I.
