Hi, thanks to those who have completed my survey so far, unfortunately as the hand in deadline is looming I've closed the survey to give myself time to analyse the results. Cheers

Hello. I have created a survey for my dissertation regarding hybrid/environmentally friendly vehicles in Motorsport and it would be great to hear the opinions of all people involved in Motorsport. Should not take any longer than 5 mins and will be a great help with my project. Thankyou in...

Nice one cheers, there's no cast iron on this head so that's alright. The seats are actually in good condition so honestly I don't think I'll even need coarse, just find a finer paste, maybe diamond and see how it goes. I just wanted to check that diamond paste isn't a snake oil kind of deal.

Hi, so just about to start lapping the valves into the head as part of the build and I'm just wondering on what lapping paste would be best, I know Chemico coarse/fine stuff is alright. But I've heard of a few people talking about diamond lapping paste, something like this...

It's not stock, but at the same time it's not massively modified, sort of 4/5 psi boost above standard, modified intake and exhaust and rebuilt turbo with billet impeller. Yeah hahaha it's front mount. I think people say for the modifications I've done in this car people usually get around...

Hahaha, fair enough I probably am. I'll leave this open anyway just in case anybody wants to have any input.

Yeah I understand and the intercooler itself is fairly small I've not just gone bigger is better with that it is well sized. I'm just wondering with the piping is it just possible that a bigger diameter corner the slower moving air would create slightly less turbulance and therefore not impact...

I'm not doing too much on the exhaust other than 3 inch downpipe and front pipe, I am using silicone bend reducers just obviously flipped to step it up, I did think of only stepping it up just before it is needed, i.e. before the intercooler but I am just thinking increasing the size on the exit...

The steps I am using are all silicone and they are never any more than 10mm each so they are very smooth and gradual. Basically now my only concern is after the intercooler where it jumps up from 70mm to 76mm then back down to 70mm for the throttle body, is that just going to make me loose...

Hi I'm just wanting a second opinion on the sizing of my intercooler piping. Basically from the turbo it is ~43mm internal to ~53mm external, then the intercooler is 68mm external, then the throttle body inlet is ~72mm internal - its a rubber flange type thing so a metal pipe will have to go...

True but I don't think it has to be the engine itself it's more assessing the road car vs race/rally car variants but then focusing on the power train alone so the cortina is possible

That's a pretty good point, I have already started gathering a load of specs for the escort cosworth mind you but I haven't started the assignment yet so I will do this on the side and see what I can find and then choose between the two. Cheers

Hahaha yeah true. I guess if I can't find what I truly need I'll have a trip out and talk to someone or see if there is anything of use in the student library, I'll leave this post open though in case anyone else is able to weigh in Cheers

The cosworth would be a good one, some great rally cars are powered by that of course so that'd be fun. In terms of explanations I can obviously do turbo I'd just have to do a load more research as most of my knowledge lies within N/A, I suppose there's nothing wrong with expanding my mind Yeah...

Hi basically I am now doing a degree in competition car technology and my current assignment is to take a race car and compare the engine and gearbox to its road counterpart and assess how each little spec had been altered for use in race. I do want to do a car from a slightly older class like...
