I've recenly found out someone i kno is getting rid of their old cavvy 2litre td, and I had the wacky thought of converting it into a bio-diesel sprint car. It's a standard car and would take a bit of work, but I'm prepared to do some.

Whats your thoughts?

Not sure that it is the best starting point for a sprint car but it would certainly be different

So when will we see it on the hills ?? wink

I am sure it would attract a bit of attention, tough class though, how about putting the engine in a 7 style car ?

This may be a bit cheeky, but I'm lacking in the mechanical skills department and was wondering if I could rope in any of you more skilled types to help convert the cavvy when i get my hands on it.

i can give you a hand making it very light.

i'm good at taking as much off a car as possible, 2 sierras to prove it, allthough i have to sit on a bit of wood to drive one of them and its maybe a bit noisy due to no exhaust!!

If there is a book thats tells you how its done im sure i can also lend a hand with the mechanical side.

Perhaps you should ask the experts on the hillclimb and sprint "flatchat" forum before you you strip out / modify too much and end up in the wrong class..

I've been getting alot of advice from John (tuscan_thunder) about this and by what hes saying its going to be quite simple to get it ready and on the track.

I had thoughts about building a Bio-diesel sprint car using Merc's current V6 engine. Easily remapped to 260+hp and 570 torques, enough to propel a lightweight donor car round the track at a brisk pace...

If you end up fitting a modern turbo diesel, I know of someone to remap it

I'm pretty sure the modern very high pressure direct injection diesels can't easily be converted to run on "chip fat" or the higher percentage bio-diesels - but I may be wrong.

But, as Donald says, the modern all alloy big v6 turbo diesels from Audi and Merc, as well as the new all alloy Beemer 4 cylinder diesels can be remapped to produce monster torque. With a bigger intercooler, more boost and a remap, you could be looking at getting over 300hp and over 450 lb/ft from a 3 litre 6.

Imagine that in a locaterfield.....

Steve, you are correct, the modern diesels don't take to veg oil well - the piezo injectors don't like it and the pressure a common rail diesel runs at tends to allow the oil to clog in the lines. Bio-diesel is a different issue and is far less prone to gumming up lines at high pressure.

Ian's Cavalier is fairly basic and I imagine that it will run just fine on veg oil - cold starting may be a problem but a bit of mineral diesel should help cold starting. In the summertime it should be fine on veg oil. (Famous last words....)

I have been thinking about this, could run a preheater before the oil comes in to thin it up a bit, or bigger fuel lines as well. But all the cars running mixes i know run 25/75 oil/des in winter and 50/50 in summer. The piezos are much quicker/effient that the PD's. The VAG 1.9tdi 130Pd with just a remap your looking ~175bhp and 320lbs/ft. And probably a bit lighter than a really big lump, thinking weight, or are you thinking about running this in a light car anyway? Should be cheaper to find as well.

love this... watching with intrigue! Forgive my naivety but what exactly is a sprint car?

Yeah, the remap of the Sprinter V6 has made this an awesome engine at 260hp. Timed a 0-60 the other day with 880Kg of weight + tools in the back and got a best time of 11 seconds on 3 runs....Bear in mind the total weight would have been around 3300Kg when I timed this hehe! Will try again with the van empty. Imagine that engine in a car weighing around 800Kg...
