No, no... a De-dion tube, and well, maybe a propshaft.... and er....
I've een building the thing since 2007 because I don't have too much money!

A bit off topic, as we're talking Xflow and Zetec, but as we're talking engine sounds, how about a Millington Diamond ?
Old School is Cool!

Thanks for the Zetec sound sounds alright to me, but not too many bangs on liftoff. Power seems good though..

BDR is just too much money for me, but the Colin video was great!

Not to be taken too seriosly but real old school would be 1 1172 sidevalve Ford and 3speed box or2 848 cc "a"series and 4 speed box !!!!!

But it probably needs a rebuild, and you could get a 250+ hp Cosworth Duratec 2.3 crate engine, brand new for that money.

Or this for a lot less...

Ok, some updates on the car:

My side windows were quite badly worn. You could hardly see through them when it got a bit misty, so I figured out that I would by new ones. But being the cheap bd that I am I thought I could just buff it out. I relay like Scholl Concept products, an gave it a about 10min with some help from my youngest son.

Here I have done a test with both the Scholl 3Gold, and the Scholl 17. I went for the 17 compound but either works. As you can see the windows were horrible, and you can the effect of the compound. The screens looks almost like new!

Not that easy to see, but they look amazing compared the the before state.

Went to a track day today, just to get a fell for what I need to do over the winter.
First I was stopped in scruiteny for having 102db. After some negotiation I ended up at 99 and was let out on the track.

I had a friend with me, which has never driven on track before so the car was a bit heavy but it works! In the twisty bits it is realy good. Managed to keep up with all the other cars. On the straights it is just too low geared. This was on original tyres, about 15 years old! Original bushings in the front and standard xflow engine.

Based on this experience the winters plan wil be:
Bolted cage
Zetec with 150+bhp
Type 9
Shocks
bushings


Stay tuned

The cage will stiffen her up quite a bit

Getting parts for the winterproject together....

I don't necessarily disagree with you, but I never planned for this to be a concurs project. I find it more fun to try things and be creative. Sometimes I do quality work, sometimes I emphasis speed. For me to be able to do this car I have to work fast, hence some quick fixes. The main thing for me though, is that it works.

As far as the cycle wings, the opinion differ. Some like it, some don't. You apparently don't. If you look at function, clamshells are better at protecting occupants and rear wings from stone chips. Cycle wings on the other hand are way lighter and more fun to watch while driving, since you can see the movement of the wheel/wing.

As for further modifications that is what MY car hobby is all about: I like to try new things and continuously modify and change. Sometimes it works out, sometimes it doesn't. Some like to polish and detail their cars, others again like to keep it 110% original. I can appreciate that, but it is not what MY car hobby is about.

This winters I will swap the engine. Why? Because I find it fun to do the job, and learn new stuff. This time it will be Megasquirt and TunerStudio which is the "new" thing for me.
And I'll guess I will find a 560kg car with 200bhp more fun than a 580kg car with 100(old)BHP, but that is just speculation.....

Here are a few other modified S4s taken of the net. I guess I am not the only one modifying these cars...
