Good Imp Racing news from Norway! (video)

Post by knutspeed » Mon May 13, 2013 7:16 am

It's been a long time coming, but yesterday we finally managed to get both Imps to the finish! In style as well, as we netted 3rd overall, 1 class win (1300cc pre 71 FIA) and 1 class 4th. 20+ cars in the race, finally got to give the Minis a good fight!
Saturdays races were looking good until the last couple of laps when both cars stopped for truly silly reasons - one broken rotor arm, and one dead condenser. Gotta love those far-east spare parts...proper items now fitted of course.

George, the Bevan tribute car has a new Norwegian, locally built engine which ran perfectly. Most impressive was the fact that it was so clean post-race, I'd have no problems serving a 3-course dinner on it!

Videos etc, and some tech/set-up questions to follow!

Thanks for the positive feedback!

Managed to hack some video from this weekend, both cars, various camera angles. The blue car sounds like a mini-DFV when off the throttle!

Thanks for posting, great battle with the yellow mini towards the end :o (he cracked under pressure eventually :D )

Anything stiffer than 800lbs rear springs available?!

You've got too much grip! With Dunlop historic crossplies, 800 is OK.

Trouble is - here I'm running Yokohamas, but I would have been running the much wider Avon ACB10s if I had the clearance...we run those on the other car no problems, and the grip is fantastic. Period G (71) - no chance to run the (fun) Dunlops - i'd be way off the pace.

The Yokos didn't feel that grippy, believe me I'd like more! Gimme Scalextric performance!

he cracked under pressure
Indeed he did : And it wasn't too far away from a whole bunch of Armco, by the looks of things :o

Maybe try a relatively soft rear anti-roll bar?

I think George Bevan used the narrow springs inside the normal ones to achieve some sort of progressive action. On some occasions anyway.
The rightmost one is an 800 racing. Sorry I don't know specs for the smaller one.

We had a look at the rear, and everything seems ok. Fredrik has fitted Bevan-style helper springs with shims, we'll see what that does. The car sat very low at the rear on the Yokohamas, might be that the R/F weight distr. was offset even worse which amplified the one-wheeling. Previous springs were softer, but taller than the 800s.

We'll also bring some other dampers to try if this doesn't cure it. The plan is to run the fat ACB10s at Velodromloppet in just over 3 weeks. Challenge is, they're not much good if it rains compared to Yokos so we'll need to get the rear ride height set up for both sets of wheels which are quite a bit different in circumference. Should be a hi-lo kit available for Imps :wink:

Theres also video from a Norwegian sports channel covering the races with good shots of both Imps (norwegian commentary, but good video). http://vimeo.com/66625469 (go to about 10 mins into the film to bypass the rather ugly locosts).

Rally champ and legend Stig Blomqvist ran a Ford Galaxie, and of course, won overall after a good battle with an Elan.

You can make the rear height adjustable very easily. In involves drilling and tapping the the bottom of the spring holder in the trailing arm at three equidistant positions. You then cut a rigid thin steel disc to fit in the bottom of the spring seat. Bolts are then screwed into the previously tapped holes to raise/lower the plate and thus the spring. You will also need to fit nuts to bolts so that they can be locked off against the underside of the spring holder. Hope that makes sense. Works fine at altering the rear ride height on my Clan.

Sounds a good idea, thanks! Will have to check if it's allowed in app K, or maybe somebody knows?

I think it's not if it's allowed but if its specifically not allowed!

Thanks Lars, the secondary springs will be fitted to Matt's (blue) car for Velodromloppet. I have a pair which came with the ex-Chrysler Sweden Imp run in the mid-Seventies, for Slim Borgudd (originally built by Ivor Goodwin) and purchased by me from Mats Warg of Falun...just about to finish machining an alloy "top hat" for twin springs, to fit in the chassis spring towers in order to locate the inner spring properly.
Incidentally, with Matt's car and mine being entered for Karlskoga, there will also be a pair of Danish Imps for the Historic Grand Prix as well.
However, the organizers have seen fit to amalgamate saloons and GT cars in the up to 1972 class...so we now face taking on a Ford GT40, no less, in our race...which may prove to be a bit of a challenge, even if our Imps are pretty quick :roll:
