Thanks Nikki. That's great to hear about Radical helping get your devices integrated. I really think my case of the old ECU and older GCU was just too hard -- or perhaps they thought I couldn't do t...

Last night's project was the vacuum manifold. Each of the just created throttle body vacuum ports will be connected to the manifold. There are two additional ports: one goes to the MAP sensor (the who...

The original 3-piece Wheel was from Image; I ordered spares last year directly from them.

One of the first sub-tasks is to modify the throttle bodies to support a MAP (manifold absolute pressure, aka vacuum) sensor. There are no provisions for a vacuum port anywhere on them. Jenvey (the OE...

I'm upgrading my SR8 to a MoTeC M150 GPRP (general purpose racing paddle shift) controller. I found that the gearbox controller (by Geartronics) was so old that the tuning software didn't work, and th...

Radical is now selling one piece wheels that are much more reasonable than the original 3 piece design. I bought new ones from Spring Mountain for $2500 for a set. I'm a Forgeline dealer, and I spok...

Hello all. Thanks Charley! I've been wondering why there wasn't a dedicated Radical forum! My (current) Radical is a 2007 SR8, which I've been working on and (rarely) driving for the past 2 years. I'v...

Graeme, your story sounds like mine, and, I suspect, like a lot of Radical owners. My interests came via old muscle cars to Corvettes, to a track-only Z06 'Vette. I too got tired of fixing things like...

It's a pleasure to be part of the community... I will try to get some pictures out of the ECU installation soon. The car is in the workshop at the moment... 🙂 Regarding Spa, I've not made a calendar y...

Forgot to say... We have a YouTube channel where you can check out other videos of Hotlaps onboard our SR3 at various European tracks:

Thanks for the comments on the video. I must admit that I also have a dream to drive at Laguna Seca one day... I love the track on the Playstation and hope I can drive it "for real" sometime. We will ...

I like it, when's the radical owner's goodwill delegation going?

After the weekend, I can say the brakes are 500% better! Much more sensitive to the pedal. A quick look at the data shows much less pressure for the same deceleration G's. Mostly zero overlap, only ...

Thank you for the welcome Charley. We primarily rent for trackdays and have had very little request so far for actual racing, which is something we've been doing more for customer-owned cars. We have ...

Great footage !
