V8 DNA 4thirty

[paulm]

Shocking on the exhaust,  

Mind you the manifolds you dont really need, or if you wanted to play around you can get a set from a red bull or torro rosso on ebay for about £300.

Sports cats in stainless are now less than £200 each, but make sure you get the shortest ones as the centre pipes are only about 350mm long..see below.
Back box might be a good option though, if you cant find a cheap Ferrari box.

This is what myself and DNA looked at doing together at the end of 2008. This back box is the 360

360 or 430 box will work, the 430 may be better but harder to get hold of.

Cheers Paul, I'll look into this when I'm back onto the rear of the car fabrication.

Hi D

I bought a 360 exhaust over a year ago payed just over £400 for it if you want it just make me an offer and its yours, It wont be any good to me as i think it will sound funny coming from a standard 1.8vvti engine compared to a V8 monster conversion 

So thats the back box with both tail pipes

I've pm'd you

Work is slow at the mo, a lot of head scratching to make parts fit, there isn't enough room in the wheel arch for the Audi bits. So I've had to start moddifying.
 i) The top trailing arms are too long so I've cut drilled and tapped joing each section together with some studding, they're now adjustable. ditto for other side
 ii) The hub upright is too long, again it's a cut and shut.
 iii) The steering arm's on the wrong side, so I'm moving it to the other side.
 A majority of these changes are welded in place and although I am a welder I've spoken directly to the filler/rod manufacturer regarding their recommended procedure. I've produced a couple of test pieces and hit them with all my might, not one failure, I'm now happy.
 The front alteration is going slower than I'd like but it's definitely doable.
 I just take one look at the disc and caliper to keep me motivated.

A pleasure Darren

I went down to see the great V8 Build, Ive got to say you is one gifted guy  , The kit really is a solid piece of work, il be visiting the guys them self soon ............. WATCH THIS SPACE

I hope its works out for you just pm me when your ready

p.s i hope im one of the first to experience the power of your beast 

Speak soon and keep up the great job

[dangerrous]

Your kit will probably be finished before mine!

Thanks for letting me borrow the exhaust, it gave me a chance to look at the Ferrari option, unfortunately it would have meant too much work, the tubi design will be a possible alternative.
Thanks again.
NB; Now you've got your Large DNA workshop almost finished things will really start moving

It's been a busy few weeks with the front suspension and steering set up.
 My main problem was to overcome the wheel hitting the two top arms, I've had to reduce the hub height twice!
 To keep the hub mounts correct I fabricated two more jigs before I could even start to think about welding it together.
 The hub steering arm was in the wrong place So with the aid of another jig it's gone from the top back to the bottom front, this is welded and bolted in place.
 The nickle rods have been a pleasure to work with and I've completed several strength tests on discarded bits of the wheel hub, I was satisfied with the outcome.
There are a few reasons I've perservered.
 1) The width of the Audi wheel base is close if not the same as the Ferrari (no spacer/stud pattern converters)
 2) It holds massive discs and calipers as standard
 3) The suspension geometry is a work of art, which ever way the steering is pointing the front wheels are cambered accordingly; both wheels are pushed into the tarmac
 A suspension web blog describes it as the next step in suspension/steering evolution
 4) Again with the suspension- each top and bottom arm is independent and offset, so when you turn the steering it will take the wheel back and forward, opposite to that of a standard set up, with the correct wheel there's no arc of movement as the steering is turned.

This has turned out to be as much work as the back and I'm glad it's almost over, I just need to fabricate mounts for the steering rack.

Here's a picture of the extended steering arm, I shortened the toyota arm and ran a 12mm die down the end, then tapped out the cut up Audi steering arm ball joint and joined it together, no welding involved just a lot of screwing!

just awesome work fella.. I hope I get to see the car one day :-)

Are you intending to keep her?

I always considered a 'joy factor' shelf life of 2 years.
 Let's see what happens

Once I've bolted down the steering rack, I fancy a little cleaning up, so I'll sand blast the front calipers and hubs, spray with zinc ready for paint.

This thread makes me warm and fuzzy all over.

Dangerous, are you still utilizing the stock Audi suspension geometry? Will you be using an aftermarket coilover setup? If so, will you order them for an MR2 or the Audi? Or do you have a trick up your sleeve we don't know about yet?

Really great project, keep up the fantastic work!
