Engine In Mule

[robo]

I got the chassis cheap on ebay just to use for mock and the engine is just an old block I had kicking about. The mule chassis has given me a chance to sus out where and what engine,gearbox, suspension and axles I can use, its been worth its weight in gold as far as this project goes.It will live again as a mock up as dadofseven is coming to get it to mess with his beemer v8. I am using a new talon chassis so hopefully wont need to de rust

Glad you said that Bob & even happier that I didn't mention the rust

Seriously though, that engine is going to look awesome in a Roadster.

Look forward to following your progress.

That inlet manifold looks a little out of place of the old block and test chassis! What the plan for the rest of the build? Be interested in seeing what gearbox and rear drive your going to fit in. Be nice to see some alternatives coming through for the Haynes.

I will drag out what I have gathered and take some snaps. Many shiney bits

But why?
Its a nice looking engine, will probably make serious HP and perfect for a Cobra, but a Seven...
Its heavy - Sevens are all about handling and being nimble - and how would you put that power on the road? You will end up with a car that would not be enjoyable to drive, everytime you put the hammer down, it would break away at the stern, more so in bends

Im not a profit of doom, but is it not better to have a sharp handling car with just enough power so you can drive it flat out and on the limits?

I have a problem myself in this regard - my ride's (nearly completed) engine is a 3SGTE (weights only a little more than a 4AGE) that makes about 190kw (255hp odd) and I already considering turning the factory boost level down from about 9psi to about 6 - 7 psi. A chap in NZ has the same motor in his chariot and actually got wheel spin in 5th gear on the track - and that is frightening

Something to ponder about. A Caterham R400 has about 210hp and goes like a bat out of hell and probably the closest thing to motoring nirvana.

The reason I am using the ford 302 is because its a real lightweight. I have weighed it against a pinto [dry] and its about 3kg heavier. If I shove ali heads on it becomes about 15 kg lighter. The power thing is a non issue because there is a throttle pedal fitted not an on/off switch. A guy up the road took me for a spin in a caterham that was making about 300hp and there were no wheelspin problems , it just dug in and f@@ked off. This has been covered before ,yes if you stamp on the loud pedal it wil swap ends but that is true of any high hp car. That car of yours will not be a problem just get used to it slowly.

A very compact design, the small block engine utilizes a thin-wall block casting not extended below the crankshaft centerline. Expanded to include the 260, 289, and 302, the engine family has provided power for most of Fords model lineup. Cylinder bore spacing is 4.38", the same as the Cleveland family. The small block is externally one of the smallest V-8 engines made, and total engine weight is around 460 lbs. The 289 was produced from 1963 to 1968.

In 1963 Ford released the 289 High Performance
which produced 271 BHP @ 6000 RPM.

It will look the part & sound great.
Personally, I am a huge fan of the sound of a well tuned V8 engine.

I read lots of threads & posts on the subject of track performance.
This is fantastic if that is what floats your boat & are building a track orientated car.
So in that respect, I can see where you are coming from.

Me, I probably fall into a very small minority of builders.
I am not a very aggressive driver & do not have a craving for ultimate speed or performance.
For me the build is all about owning a 7'alike that I can potter about in on a nice sunny day.

That said, I do want enough power to be able to P**s on the fireworks of the local chav in his hot hatch
Although I am not a nippy driver, I am certainly not afraid of the loud pedal.

Bob is no stranger to the kit car world & I am sure he has done the maths.

One thing is for sure, his build will turn out to be a joy to behold.

Having just spent a blissful weekend at Goodwood for the Festival of Speed watching machinery with ridiculous BHP figures thundering up the hill I say why not?
will finish this comment later as a customer has just turned up.

And why not indeed he I was not to tight and lazy I would have looked into using a v8 thunder maker in my build but since I am so tight and lazy I am using the mx5 parts

Right I can now devote some time to this reply . If Robbo wants to use a V8 then I say go ahead, knock yourself out and do it. Weight issues? What weight issues? As Robbo has already said the difference between his small block V8 and a pinto is minimal and if the V8 is well back in the engine bay the overall effect on handling will be minimal. Too much power? F1 cars rev to 18,000RPM and put out C750BHP in a chassis that breaks the scales at around 650KGs, they manage quite well albeit with very good drivers. So why does a couple of hundred BHP in a 600KG(ish) give cause for concern? As Robbo said the throttle pedal he is using is a VARIABLE control not an on/off switch.

My build was recently referred to as a "barge" (conveniently edited later to be less offensive although no apology was ever forthcoming) by someone who lasted nearly six months as a supplier of chassis and body components. My build will weigh around 750KGs when finished (how many of you have any idea what yours will weigh, honestly?) but will have around 225BHP and 200+ ft/lbs of torque from low down (around 2000RPM) with a pretty flat torque curve. This means it will be lighter than almost all standard production cars and pull like a train! If I get the suspension geometry right it might even go round a corner or two .
