985cc Turbocharged Nova Sprint Car

Good result so far Colin

Without going back through 101 pages - what was the weight when you first started ?

Off the top of my head it was 614kg.

Was great to see this in the flesh, great bit of kit - and cheers for the tour colin - i'd love your place!

Got the brakes bled yesterday, and the wide rear arches pop rivetted into place.

It's not going to be looking terribly pretty for the racing this weekend, as I won't have time to get the arches blended in and professionally painted.

A few aerosols of red paint will have to suffice.

It's a shame as there might be a TV opportunity, as 'Fifth Gear' are there (at Gurston Down) to film Tiff Needell driving the Ariel Atom V8.

I took the Nova for the first test run since doing all this work, and it's much quicker than before.

Unfortunately I have issues with the brakes.......the new KAD discs on the back are locking up too early, and no amount of fiddling with the bias valve seems to help.

Further experimenting will continue today on the brake rollers at the local MoT station.

I'm not sure if the bias valve is to blame (it was OK last season), or whether these discs are just too efficient, especially when coupled with the weight loss that's happened at the back end.

I've got another bias valve I can try, but failing that I think the only cure (short-term), is to somehow reduce the efficiency of the rear brakes, possibly by removing part of the rear brake pad area.

you could get some lairy as feck pads that need a LOT of heat in them to start working.... That way the fronts will do the bulk of the work until the rears get a little heat in and they start to do their job.

if you are really struggling, you could grind some grooves in the pads or remove some pad material

edit: read something wrong.

or a well placed air bubble!

[Stuart]

Does he REALLY need rear brakes at all though.... So vaugely working ones will be more than adequate imho

CP's old trick after he fitted Wilwood two pots on the rear

i agree for years very inadequate drums served novas well, rear discs are purely a vanity modification on nova's (obviously in this instance its for weight saving).
