Rather than debating on the numbers, reliability and other shit, some people should put that energy into building an engine but I guess its easier to write messages on a forum... If they say 1200bhp why not ? The greeks are known for building powerful cars for the 1/4 mile, that's no surprise. The build quality of that specific car looks really nice, for a change.

hi matt
sorry mate i only started the thread because i thought it was a acheivment and credit to them for pushing the bounderys

it is making around 1150 horsepower at the wheels its performance has proved it, 178 mph in 1/4 mile is phenomenal.

does anyone have a link to a thread or any info on the car, i dont have the mag

Nothing against you mate, its just reading some comments in this thread made were a bit like insulting their work. I'm not greek, I've nothing to do with them, but as you said, its quite an achievement !

first 200m 218 kmh 18m 1,4sec the car have big traction issues ,,, in other , more drag speciall surface ,the numper i think is lower .... in greece the name cosworth rules ......... i am sure all be hapy with it.... sory for my english.....

Imho it is an amazing car and build, no matter how many bhp it is.

puddy

I know for a fact that Jt's probe was running in the 170's and a 7.50's and that had a julian

built ybt in it with no more than 900 bhp at the fly,where does that leave your graph ?

Can't compare the probe to the subject escort as the probe is a full drag car where as although the escort is built for drag racing it's still steel bodied weighs 1100kg and is 4wd, it's pretty obvious from the times it's achieved that it got to be around the claimed power. 178mph over the quarter takes some doing! The probe would be a lot lighter probably not far off half the weight.

another atempt it is clear that ,in greece they dont have santa pod ...

i fpmsl what does the probe weigh ? without knowing that you cant tell anything from it

the graph comes from a very reputable source.

Jasu

What is wrong in that?

Do you think that there is no durable head gasket?
That people (in general) can afford to try something like that?
Or are you saying that such an engine is reliable?

Please tell me?

Here the ybt probe

Here's some info on what the BMW turbo F1 cars were believed to be running that i found a while ago.




Then BMW had their breakthrough. At the time they wore supplying engines to Bernie Ecclestone’s Brabham team, who had successfully re-introduced refuelling the previous season.

The fuel regulations at the time demanded that the petrol used in cars be similar to that used in road cars. But the loose wording of the regulations gave the imaginative BMW technicians some wiggle room.

They realised that they could produce a legal fuel that did not exceed the regulatory limit of 102 octane (octane being a measure of petroleum-based fuel performance) incorporating toluene.

Toluene (or methylbenzene) is a hydrocarbon derived from petrol that burned more rapidly, created more heat energy (both of which provided more power) and was more resistant to the problems of ‘detonation’ which impaired performance.

The developments that came on-stream late in 1983 allowed Nelson Piquet to snatch the drivers’ title from Alain Prost at the final round in Kyalami. But there was more to come from the super-fuel.

Boost pressured skyrocketed from 2.5-3 in 1985 to as high as 5.4 over subsequent seasons.

Exactly how much power these engines produced has been the subject of wild speculation – a figure of 1,500hp has been widely cast about with little evidence.

BMW’s dynamometer was not capable of giving a precise reading for the power output but they estimated it at around 1,300hp – a truly staggering figure for a 1.5 litre engine.

This came at a price – the fuels contained around 80% toluene and were poisonous and enormously expensive, costing up to USD $300 per litre at the time.

The FIA ultimately acted by limiting the boost pressure and, eventually, banning turbos – a topic we’ll cover in a future installment of this column.

But what about the Nazi link?

Legend has it that these exotic toluene-based fuels were similar to those used by the Nazis in their WWII aircraft.

BMW concocted the potions with BASF – a company that during the Second World War had been part of IG Farben: the company that synthesized fuel from coal for the Nazis when the allies blocked their oil imports.

But the tale is not true – the fuel used by BMW shared only a small number of compounds in very small quantities with the Nazi aviation fuel.

Still, it made for a good story…



They used to have a BMW F1 turbo engine in the old nurburgring museum where you could actually get close and touch the displays before they ruined it with the new one. Amazing components on it that you still don't see on cars today and these were built 30 years ago.

v man

I remember a while ago now that a guy think he was from Malta wire rung the hole block alround the water and oil ways etc etc to cure his head gasket problems

Big wire aswell

grcossie

That has been done by Martin Schance (mr rallycross) many years ago on yb rallycross engines

Dimma4x4

He all ready is ha ha

puddy

I will go and ask him then,he still has the probe although the engine ultimately ended up

over most of Julians dyno cell, twice.

jesus that head is Ł6650 + vat on it's own! I'd expect some serious poke from that!

May sound a stupid q but will it not need a HG as block & head made of same material so will expand/contratct at same rate? It might be an urban myth but did porsche not make a block from resin for the 917 for the same reason?

It does seem that hp figures from some greek and to the same extent norweigan/swedish engines are a touch optimistic compared to the UK - perhaps their horses aren't as fit as ours

keen to see this at autosport anyway.

Think you will be surprised mate probably around 850 / 900 kilos

Hopefully one of these engines will find it's way into a car or 2 at some point and prove itself. It's a very interesting development and it's great to see that people are still willing to push the boundaries of the yb. I'm sure there would be customers who would buy the engines for Geoff page to throw all this tine/ development into this new engine.

Didn't realise the probe had gone as low as 7.5 secs? That's in the top 20 fastest 4 pots in the world if it has.

if its around 900 kgs with driver it will mean around 850 wheel horsepower roughly, i cant work it out as i cant find any order to the graph to calculate the lower weights area but that will be close enough.

my supra and my gtr santa pod terminals were within 1 mph of that graph, for 500 whp and 700 whp which is about what they would of made whp on a dyno dynamics, the r32 made 460 at 1.2 bar and ran 1.4 bar at pod on its final tune.

You can use Cooper or Beryllium rings to seal the combustion chamber to the cylinder bores and either 'o' ring the oil and waterways or use external link pipes.
Both tried and tested methods for both alloy head, alloy block, alloy head, cast iron combinations.

I think that graph is a good guide ,as my car was 1080 kg with me in it and 490 atw and 9.7 @ 143 although I sold it after I ran the time I think it would of gone a little quicker with flat shifting ,but looking at the graph you posted its not far out

Cheers Steve, you're much more knowledgable than me
