Nice hillclimb / autox(?) car for sale in the UK
A Radical - 12,000 pounds sterling... What a car for the price, hey?

I think they are awesome. Every year more used ones seem to hit the market at lower prices. I think the SR8 holds the track record on the top gear course.
SR3
It is the world’s most successful sports-racer, with over 1000 satisfied customers. The SR3 is a sure-footed, highly-developed racer, adept and rapid in the hands of both the novice trackday driver and seasoned racing professional. The SR3 is powered by the Powertec four-cylinder range of engines, from 1340cc to 1500cc and beyond. It’s a proven class winner, not only in Radical’s single-marque race series, but many other multi-marque championships around the world too.
SR8
This is Radical’s ultimate racer, and it provides the definitive visceral driving experience. Physics-defying grip, relentless acceleration and powerful brakes add up to a two-seater track car that can lap Silverstone in the same time as a Formula 3 single-seater – and at a fraction of the price. The SR8 shares similar styling and safety features with its sibling the SR3 RS, but it beats with a different heart. The latest generation of Powertec’s acclaimed RP V8 engine, powers the SR8.
PR6
The PR6’s central seating position chassis is Radical’s lightest and most nimble to-date. The aerodynamics are up-to-the-minute, with huge amounts of downforce being generated by the SR9 Le Mans Prototype-inspired underbody diffusers. A fully FIA tested frontal crash box and MSA approved safety cell, gives drivers the confidence to explore the limits of the PR6’s very predictable handling.

There are lots of Radicals around. Later ones are better than earlier. Compared to other cars in SCCA, they are too heavy and underpowered to be competitive. Google will tell you lots about them.

Umm.... http://www.youtube.com/watch?v=Ca2124n1-kQ
not bad right off the trailer with track setup. Sure does turn.

A bit squirelly. Dang I want to drive one of those.

Sorry, I was talking racing. They were CSR/DSR and got killed by other cars. Not sure which of the new SR classes they are in. Same story I'm sure.
They are good cars, just not amazing. If you want to see something amazing, look at the Ralt or Swift FA that are converted to C or D Sports Racer.

What is interesting is the (used) prices and what you get for that. In my case currently not interested in track work, but one of those would make a great hill climb car and likely autox as well. Softer shocks and A15 Avons and you'd have a pretty quick autox machine. Perfect for venues like the Medford Enduro as well.
I like the Ralt or Swift FA cars as well, but clearly a much bigger step.

If you want something to hill climb and autox, there are tons of options that are cheaper or the same as a Radical. People have put bodies on FV, FF, and FC cars for a long time. A club continental with a body would be very fast, on par with or quicker than a radical. Look at S2000 cars too.

I like the words very fast. Throw "handle" into that sentence and I'm happy.
Or give me my car with 300RWHP and I'll go away happy. And I'm not interested in running anything except a Porsche motor and I'd like it to be below 3.0 liters. A 300RWHP motor under 3.0 liters could be built, but you're looking at major money.
Ahhhh.. easy to see why the $15,000 Radical looks interesting.

To me a $15k Radical looks like a car that is going to need $10k of work.
Remember, everyone's version of "race ready" is different.

Spent a lot of time on the UK hillclimb website. This is a winning car that has a lot of positive feedback.
But being realistic, it will likely need work.
On the other hand I doubt the owner would be cleaning up on the hills if it wasn't solid. Driving hillclimbsg, in something that isn't solid, would be pretty crazy. Not the place you want any failure.

12k pounds is $20,000. In the US, a good one is ~$25k or more from what I've seen.

Unless you go forced induction...
Posted by: SirAndy Nov 6 2013, 01:44 AM
A 2.7 with a supercharger can get to 300HP at the wheels EASY ...
In fact, Ferry Porsche build a 1.5L (one.point.five.liter)!!! in 1949 for Cisitalia that used a supercharger to put out 450HP.
In 1949! Seriously!
Posted by: bulitt Nov 6 2013, 06:13 AM
Looks like the owner swapped the Honda with a Kawasaki. Think you can also run a Busa motor and they are turning up to @290hp. 260hp package for about 7000$ And they weigh 220lbs for the engine alone yikes.

I've noodled a bunch on that, but not willing to take my expensive motor and experiment.
Kind of like supercharging, but just wish there was a good source for Type IV motors that was proven. Like wouldn't it be nice if there was someone like CB Performance for Type 4 induction motors. They have built hundreds of turbo motors for the sand rail fans and their failure rate is super low.
On the other hand Andy's suggestion of a turbo 2.7 would definitely get the job done. Great for hill climbs, no question. Not sure how good it would be in autoxing as you'd be adding a bunch of weight. Um mm. Yea, a smaller turbo to spool up fast out of corners.. Give me torque every time.

Now I may have to build a 2270 turbo and terrorize some AX venues. 
I did just acquire a 912 and the would be perfect for it...

I did just acquire a 912 and the would be perfect for it... You need more than a motor to terrorize an autox venue, although if the motor is 250-275HP at the crank I know a car we can put it in that would terrorize the autox venues.
And think torque...
Posted by: McMark Nov 7 2013, 10:00 PM
Not a bad idea...
Thinking a Garrett T3/T4 with a specialized turbine and compressor for low end torque. But on the other hand I'm partial to the OE Porsche style KKK turbos (just because I have that nasty OE streak). But, yeah, all about the low torque. No point to 6000 rpm boost on a AX course.
Posted by: McMark Nov 7 2013, 10:53 PM
Hmmm.... the K16 turbo is used on the 997TT. That's a 3.6 with two turbos, so each turbo is seeing ~1.8l. I bet that would come in nicely on a 2270.

Need some sort of fancy software to run the variable turbine. Its a trick setup. Those cars boost off idle.

None of the K16 I've looked at have VVT.

Would be perfect for hillclimbs, but classing, in SCCA would kill it for autox.
Nice part, build a subframe to hold it and you're done.
Scared to ask the weight.

Looks like they're available withoot them. I'll have to see if I can find an actual model number on the turbos for the 997. VVT also doesn't use waste gates.

Looks like 2525 for SSM on 275 tires. Add 200 lbs for anything wider. 2200 for XP. Great price on it though.

2200, ouch! SCCA rules are ass backwards, should be based upon HP, not CC'S.
On the other hand it sure would make a good hill climb motor. And could use it at Medford.
Wonder what the motor, transmission and suspension pieces weigh? Probably 700lbs.
