CHASSIS / Factory Audi TT-RS racer bespoke FWD suspenson

Apparently the fastest FWD racer there has ever been - quicker than GT3's in the wet round the ring

Totally bespoke front suspension from Audi Sport using Revo-knuckle type design.....this is the future lads!

ENGINES / Bioethanol and E85
« on: November 10, 2013, 10:26:45 am »
Hi All

Have had a thought project ongoing for some time about using ethanol to power my car, or more specifically E85, 85% anhydrous ethanol, 15% petrol. This was available in uk a few years ago at the pump, mainly at Morrisons Supermarkets, but now i dont think it is. It is however available all over Europe at about 1euro per liter.

Why is this if interest to performance car buffs? Well it has high octane, and runs very cool not unlike methanol. But it doesnt have the downsides of methanol such as hydroscopic nature, and it doesnt rot everything it contacts.

My engine man has done several race motors now to run E85 and says its fantastic. But, to get the most out if it, an engine has to be built to run it, high compression and with at least 30% more fuel flow capability. Mapping is different to petrol.

So.....i have been in discussions with msa about using it and they are ok with the idea so long as a specified fuel source is used, and the championship regs say its ok. Its possible this might happen for 2015.

I have found a source where 97% ethanol is available for under £1 per liter. To buy E85 from motorsport fuel suppliers is 3.50-4.50/liter. But i have been told discounts would be available for championship use.

Very interesting stuff, more power, burns lovely, cool running

Watch this space, may well build a alco screamer engine

Ave it


ANY IDEAS? / Forum parts buisness
« on: November 09, 2013, 09:48:15 am »
Hiya, just floating this idea but dont want it to have any impact on Jasons growing buisness at all, idea is to enhance.....but if its stupid, please delete.

Tom has just made those lovely steering rack brackets. I have loads of bits i have had made, eg adjustible arbs. There us a massive shortage of pukka race bits for our cars. How about we make them available here? Also, with the engineering excellence presence, we should fill the gaps for the bits not available today.

I could start a list....but lets see what Jason thinks first.

ENGINES / 8v engines: how quaint

When 16v heads are available, why waste all that time and effort on 8v heads?


What am i missing?

ENGINES / geared starter motors
« on: July 07, 2012, 08:30:03 am »
Sometimes my car is a swine to start. Imagine this is due to high CR. What are folks usung in race motors for starters? Is a geared one available somewhere?

CHASSIS / Hillclimb tyres
« on: July 07, 2012, 08:27:46 am »

Conventional wisdom suggests that Avon crossplies are the way to go, usually supersoft A15 or A39 compound. Personally i dont get on with them, but maybe thats because my car is too heavy at 950kg. Radials are better for me, but supersoft compounds are scarce. Have used michelin moulded rally slick NO2 to some success, and similar Dunlop CR311 in 'wet' X22 seems good, although i have not personally used it.

What are your experiences?
