Ultima Can-Am vs Radical SR3
Discussion
pstockley said: I don't think the comparision with the radical in the video is particularly fair. The radical in the video is an 1100cc clubsport. If it had the 1500cc busa engine I think the story would be different. The big advantage the radical has is weight and downforce. Especially on fast corners the radical will be a lot faster than a stock GTR. Now if you have big HP and long straights the GTR is at an advantage. Above about 140mph the Radical will start to loose out.
So if you had more power (Hayabusa turbo kit to 400 nags), plus a longer gearbox (is this possible/available?) the Radical would win out on most tracks? Stig said the Ultima in the vid was an 'older' one, so would the newer ones be much quicker, compensating for that Radical being a 1100? Does the Radical or Ultima hold any lap records around circuits in the UK - I've seen the Bedford Autodrome time, but there's no Ultima mentioned in the comparison.
I've only seen articles comparing the Radical with eg the Westfield, Ariel Atom, etc. I think it should be put against a Stealth and a Can-Am. Are you listening Evo magazine

The Ultima can run 10,9/150 on 540hp,ted told me
And why should the drive shaft brake,the heavy duty items are listed for 1000hp
My car ran 11.4 sec with bad traction. When I did get the start right and got traction I wasted a CV joint on the N/S drive shaft.
It only broke beacause Ford ones had mistakenly been fitted to my drive shafts instead of the GKN ones, I have now rectified this and am confident it will get down to very low 11's maybe high 10's.
Teds car that did 10.9 was a race car and weighed much less than my can-am (miles lighter than a GTR) and I may have dificulty matching it, but I will have a go.
As a point the ford CV's actually lasted very well and survived many miles on the road and track. (can't reliably cope with 500+bhp though)
Strange this it not the way I heard the story
It feels nice to know that I have manged to run 10,41 on my street driven Supra mkiv that weigts 3800lbs

I have heard stories of an ultima being driven around Bedford by a very quick ex F1 driver well known for developing the fastest car in the world. Also you can spec an ultima to what you want so if you want rose joinst you can have them. Look at some of the ultima's PH such as gareth and you will see.

I think a 400hp busa would probably last 10 laps in a car before letting go. Holeshot racing have produced turbo busa setups with 300 - 320hp that seem quite reliable. I am not sure if the quaife transaxle in the SR3 could take the extra stress though. Maybe it would be OK but probably not for drag racing. However, with that sort of power you would beat all but a race prepared Ultima around a track. Top end would still be in the GTR's favour but on most tracks that isn't the deciding factor. However, the SR3 really is a race car that could be used on the street. I think the Ultima makes a better street car.
As for the stealth comparison, the guys who race the Ultima also ran a Stealth B6. This was a lot faster than even their modified Ultima and had better geometry and aerodynamics. In the end they sold the Ultima. The Stealth would beat a standard Ultima on a race track by a big margin. But again I would rather have an Ultima for the street and the stealth in my eyes looks a bit ugly.

Apparently a certain ex F1 driver has a GTR powered by a BMW M5 V8 built by the factory.

You been hearing chinese whispers?...... or maybe the one were the engine exploded and I went through the lights in a ball of fire?
Mighty impressive supra to do a low 10. What spec is that.
The same day I was there a 650BHP skyline was doing impressive times at 11.5 (which was the guy's personal best)! and they weigh about the same as the supra and have 4wd.

Very good 10.41 but I bet the thing only lasts about 10,000 miles before it's F
ed. Where as the Chevy should last 50-100,000 with out to much trouble. I love Jap's and have owned Two GT4's but a good friend of mine was a TTE engine builder, and told me a 380bhp GT4 motor couldn't last the mileage I was doing. Chevy's forever...

I had it confirmed last year (Nov 2001) that the said ex-F1 driver had sold his Ultima. The contact actually worked for that ex-F1 driver!

Getting back to the original thread,
Autocar tested a 252Bhp radical and best they could manage was a 8.88 second run from 0-100mph (they never timed the 400m). A Can-am with 600Bhp should be below 7 seconds (remember mine has 526Bhp and can run 0-100 in sub 7.5 seconds).
With half the weight and similar weight distributions I would expect it to be a different story on the twisties.
For promotional stuff though the visual impact of a can-am will knock the radical for dead, if its this you are after the small advantage in the twisties won't be a problem.
Other Advantages-
A can-am;
-is more comfortable.
-is available with a soft top (I have one).
-can be built yourself (I love building cars).
-Sounds awsome.
-is easy to drive both on and off the track.
-os easy to upgrade.
-looks good in any company.
