985cc Turbocharged Nova Sprint Car

Photos to follow (probably at the weekend). I need to dig it out from storage.

Thinking about it, I now have a feeling that the adaptor for the turbo has been bolted on, rather than welded. But the photos will confirm this.

With reference to having a tubular manifold made, it isn't quite as simple as that, as tubular ones have a tendency to crack under the strain of the weight of a turbo, so need to be made from thicker gauge materials, and/or supplemented by a hanger/damper/crane of some sort, so the weight advantages aren't necessarily as great as you might hope.

Thats fantastic mate. Would be much appreciated.

jake I've been told by various people that welding it wouldn't work properly but colins obviously seems to work so i'm interested to know how his has been done.
I've thought of making a tubular manifold as ive got a spare 4 branch manifold here but could imagine profiling the 4 pipes into 1 and to a flange to be an absolute nightmare and funds don't really allow to have one made.

Fair enough mate. Wasnt having a dig at anyone was just putting the knowledge out there so you have an idea, rather than spending how ever much trying to weld an adaptor to a cast one and it ending with tears before bedtime

My brother on here dervy welded a different flange to his diesel manifold, that never cracked

Probably, depends how much carbon is in the metal itself, more carbon = more brittle = moar cracking

A proper reply.
You need nickel rods for welding cast,sure ya can mig it,i mig'd my 205 gti cracked manifold,but don't expect it to last long.
Certainly not in competition conditions anyway!

No offesense taken jake. Maybe you've read that in a tone, i didnt mean to come across that way at all mate. I appreciate your advice.

Ben,

I got some photos done today, I will try and get them posted up later on.

The adaptor flange for the turbo is bolted on, no welding involved.

Awesome stuff mate. That's good news to me if its bolted rather than welded.

Here you go, hope they are useful;

Now moved to a temporary new home on the patio, pending completion of the garage floor;

A few close-ups of the new front end;

New steering arms (rose-jointed);



Another area for a little bit of weight saving, the windscreen brace is getting replaced with carbon fibre tube;





And a new instrument binnacle, I plan to replace the existing STACK dash display with something simpler and cheaper;

That's awesome mate thanks very much for doing that. it gives me an idea of how it is possible to adapt one. Although your turbo doesn't have a standard 4 bolt fitting?
