Phil read back through this whole thread mate and read what youve said and what iv said,not once have you even thought about what iv said even on a couple of occasions iv stated some facts from people that actually built rs 500 engines for btcc race teams!!!
Then you go on about them only being used for wrc and hc when iv stated they were used long before them and known as grp a long studs!!!!
You only state what people have said to you when iv worked with and talked to alot of people that have shown me why and how things work and since then have done it with my own hands...
If you dont know how something physically works how can you make an arguement on it???
