985cc Turbocharged Nova Sprint Car

Hmm, solids will be a touch noisier, as they're not working on a big gob of relatively soft oil, but I wouldn't call it rattly. Hard to say though, as what you call rattly some might call silent

Colin are they Kent type solid lifters ,because as i have mentioned before mine used to adjust themself after some hard driving ,so much so that it used to run on 3 cylinders so we adjusted them and put a drop of weld on them to keep them correct, they were spot on then and not really noisy at all

No, we didn't go with the Kent ones in the end, the engine is using hydraulic lifters which have been adapted to make them solid, and then shimmed accordingly.

I was going to fit my rear diffuser today, but the one I got hold of is too wide really, and as you can see would need to be cut to fit around the mountings for my rear anti-roll bar.......which rather defeats the idea of a diffuser;











So I shall have to find a narrower one now. Shame as otherwise it would be a perfect fit.

Picked up a bargain set of Compomotive CXR wheels last week, which will now be my wet weather ones;

I really like the way these wheels look, and they should also fit in well with my long term plans for the change of colour scheme.







Bad news recently was that the scrutineer checking my car over at the last race meeting pointed out that my polycarbonate windows are too thin......I deliberately made them in 2mm plastic to save weight, but I failed to notice in the regulations that they have to be minimum 4mm. My own fault for being impetuous, so now I've had to fork out for a new set of 4mm ones, which I've had to get rushed through manufacture as I'm racing again on the 11th September!

I've taken the opportunity to order some with NACA ducts fitted into the rear quarter windows, as one day I'd like to mount the radiator in the rear of the car, so this will allow me to duct cold air down to it.

Photos to follow when the windows arrive.......

If you're a regular reader of this thread, you will recall I bought a Renault 5 GT Turbo just to get the 15" Image split rims from it, which was all in vain as they weighed just as heavily as the Compomotive MO and Dymag wheels I've been using on the front of the car.

Now after much searching, I have tracked down a set of Desmond Regamasters, 15" diameter and in 4 x 100mm PCD, which I am told weigh in at 3.9kg each (about half the weight of an MO).

I'm off to Norfolk to collect them in a while. I just hope they fit OK!

i dont seem to be getting update emails from any threads, loving the wheels and diffuser Colin, shame you may not use it but must be something you can do ? , i need to go on a buying spree some time soon.

Looking good Colin. I mat be interested in the diffuser, I'd need some measurements though as it may catch on the arb and as you say not much point using one if you have to cut it up !

Shame they picked up on the windows, I guess that was minimal weight saving but it does all count.

Hope the wheels work out ok for you.

How light are the Venoms, errr sorry the comps and what are they originally designed for? Suit it somehow.

When this getting repainted then Colin?

I will measure up the diffuser when I get a chance, but feel free to chase me up if I forget!!

The Regamaster wheels fit a treat, and certainly feel VERY light (even with the tyres on).

I'll get my slicks fitted on Monday, so that will give me a chance to weight them without the tyre.

I'll get my corner weight scales back tomorrow, so I can weight the Comp CXR's properly. At a guesstimate I'd say they are maybe 4kg.

They were fitted on a Jedi single seater before (they use Mini PCD on those).

A good friend of mine is having a spray booth/oven installed at his workshop down the road, so the plan is to get mine stripped and in there over Winter for a fresh coat of paint everywhere. The only question mark is the best way to get all the old paint off beforehand........I'd like to get it acid stripped but that's expensive.
