Well those of you that remember will know that i had a zed and an esprit. Anyway dave is pretty much spot on on what he has said, but i shall elaborate a bit more. The model they have is the V8 and as stock is neither intercooled or charge cooled(I believe could be wrong). On a whole they have really made a mess of it, and this has attracted alot of discussion in the esprit comunity. What they are trying to do is actually incredibly easy with a V8 all they needed to do was have bigger turbos a racing chip and then upgrade the gearbox with an upgrade from derick bell that changes the final gearing. With this it would be feesable to break 200mph. I havent followed it and infact havent seen it so dont know all the details but the conclusion in the esprit comunity is that they have gone for making TV not achieving the goal in the best way which is at the end of the day i suppose their choice, they did approach a few people and were advised of they way to go but didnt take that advise. On another note it has already been done take a look at
