Which Middy...

... has the 'longest' engine / box bay?

Reason I'm asking is that the RS4 engine is pretty much done and every time I see it I drool! A couple of weeks later, my thoughts turn to moving it on... then I see it again!

I'm thinking that once it's sat in my garage, then I'll be itching to do 'something' with it! Already established that a front-engined rear-wheel drive layout is pretty much a non-starter, so it would have to be a middy.... V8 coupled to the Audi 01X transaxle.

Looking around, most middy kits seem to adopt the transverse mid-engine layout, or cater for tiny bike engines. No use for me!

I'm certainly no chassis expert, but I guess that 'stretching' a current chassis and extending any bodywork is just a recipe for structural and handling disaster!

So thought I'd float the question... anyone offer a (reasonably priced) middy-kit that's designed for a larger longitudinal-engine layout?

PS - no 'build the Ultima' suggestions please

Not a middy but the Spire GTR can have that layout. Martin Keenan originally had a zetec bolted to an Audi Box when he mocked it up

So what is not a Middy about the Spire GTR then?

It was last time I looked.

Remind me again.

What makes the Ultima a non starter ?

Because you'll end up with something very Ultimaesque anyway.

For what it's worth.
Such an engine / gearbox combo would be all the starting point I needed to be building a mid engined sports racing car.
Oh look, here's one we prepared earlier, in a workshop not a squillion miles away from you.

Now, I know you wouldn't fit a longitudinally mounted V8 into this chassis, but when you're starting with a clean sheet of paper, you can do anything you want.

The car on the left has a longitudinally mounted engine and a Hewland.
The one below has a transverse engine.
You can do anything you want and it's your project, not someone else's.

The thought of this, more than anything is what tempts me to flog this ******* Sylva and start from scratch. Rescued attachment Sports car chassis.jpg

He used a 4 pot Audi engine and transaxle out of a G-reg Audi 80. I was re-reading the kit car magazine write up only yesterday

I'm fitting an Audi/VW 1.8T and transaxle to the Spire I'm building and the engine bay is plenty long enough for that. The driveshafts pretty much dictate engine & 'box position and there is sensible space left fore and aft of this arrangement within the engine bay. I don't think the RS4 engine will be a whole lot longer than the 1.8T 4 pot.

P.S. Don't ask me for pics cos my chassis is away on holiday at Spire at the moment for some mods.

I will have the perfect body for your engine/box, I like you need to sort a chassis, will prob end up making my own!

Awesome!!! Tell us more!!!

How did you design it, CAD model then sliced up to make the cross sections?

What ort of size will it be?


scootz - 3/4/10 at 06:23 PM

Indeed!

The Silhouette looks quite interesting!


hicost blade - 3/4/10 at 07:33 PM

Cheap too. I bet you would get that for £3.5-4k cash


Mr Noo - 3/4/10 at 10:06 PM

No CAD afraid just the old fashioned way, some 3-view drawings and various bulkhead drawings to go from, plenty of pics and a bit of guesswork. It is/will be fullsize, was aiming to use a bike engine but scrapped that idea and prob use Porsche Boxter s engine/box etc, should be ok with 250bhp, if not then could twin turb or supercharge it, but reckon it will be plenty quick enough. Will keep you poster re progress when have something more to show you all!
