@rjbender - Their marketing material says each controller (which runs 2 tires) pulls 1000 watts. We ran two controllers, 4 tires, at the last event on one Honda 2000w generator, so I'm guessing their ...

Yep we kept them on all day. Between sessions we dropped the temp to 120. About 45 minutes before the session we would set to 180.

Hello everyone, This is my first post with the forums in hopes I can rebuild my recently acquired Radical Prosport, which you can follow my progress, as I am writing articles about my adventure on Dri...

Jim, Maybe this will be of use:

Trevor, I run time trials like you. The best thing I did was order a set of tire warmers. You can go out hot on the first lap and get your times done even in 15 minute sessions. Easily the best $800 ...

@parsonsj Looks good John. What have you raised the pressure up to? I’ve just realised your chassis, or rather the frames that bolt to the chassis are different to the later SR8’s. Radical added a 5th...

So I’ve popped the back casing off my JFR and it definitely has that 3mm washer before the inner race on the layshaft. On your 1st picture Josh, I can’t see the washer, so it’s either been left out or...

Something else I remembered. I’m pretty sure the reason for changing the gear ratio settings in the gcu is so it can determine when it will allow/disallow a downshift based on rpm as to not over rev t...

Layshaft bearing, comes in 3 parts when you get a new one. Outer race, inner race and a 3mm spacer. I’m now 2nd guessing and will have to have a look in my gearbox, but I think you need the 3mm spacer...

@parsonsj Hi John, It could be an ftr with the bell housing machined off which is what some of the very early sr8’s with a hewland box ran. Don’t think there was too many of those. I’m not sure why th...

Hi Josh, That does look like a spacer issue that’s caused the failure’s. Possibly the spacer that looks like a washer (somewhere around 2-3mm thickness) and comes as part of the end case bearing for t...

Here is another SR3 for sale in the UK, it's also road legal, and less money SR3 for sale There seems to be a choice of these at the moment! Add moving the handbrake brackets etc. to the LHD conversio...

@stephen Thanks! It's track-proven now. Shifting with the RDS Geartronics firmware and MoTeC M150 is amazing. I've been able to tune any bank-to-bank differences, the car starts immediately, and I'm s...

Hi John, Very impressed with all the mods you have done. I’m surprised Jenvey didn’t tell you about the linkage they made to get rid of the short cable between the 2 banks. But looks like you have got...
