michael5556 247 Posted October 1, 2010 Report Share Posted October 1, 2010 Cool what course you doing? I used to do it at col, so if I got a de comp gasket it would make it run more efficiently? Link to post Share on other sites
ashmk3 0 Posted October 1, 2010 Report Share Posted October 1, 2010 hnc in mechanical engineering, i work in the aerospace industry and just finished my apprentiship, it may make it run more efficiently, well it must do something i shall sit over the weekend and do some sums as i have to do a project for the final bit of the course, which basically can be anything, so im thinking lightened flywheel and lower the compression and show before and after results, with moments of inertia and stresses and strains on the material etc Link to post Share on other sites
michael5556 247 Posted October 1, 2010 Report Share Posted October 1, 2010 Haha no way, I am doing a national diploma in aerospace, in my second year, where do you work? And my project is to produce around 300hp Link to post Share on other sites
FishWick 21 Posted October 1, 2010 Report Share Posted October 1, 2010 Lowering the compression ratio is purely to prevent detonation, but is now a legacy of old technology Modern turbo engines like the TT RS's run 1.2 bar on 10:1 because of the direct injection. I was speaking to a chap who builds drag cars recently and he said their 2000hp engines run 15:1 compression and 2 bar boost! And a diet of Sunoco 118 octane fuel of course ;-) Link to post Share on other sites

And my project is to produce around 300hp[blockquote][/blockquote]you can get 300hp with a good charger setup,you'll have to use a small turbo to get a low max figure of 300hp with a turbo but as the experts told me you dont want it spooling too early coz you'll run out of boost early,plus the gearbox could be an issue Link to post Share on other sites

Well done, I see you have a basic grasp of mathematics.You fail to mention turbo engines of the 70s/80s ran 8:1 or lower compression, so 10:1 and 1.2 bar is still high compression for a turbo engine. And VR6 turbos are often 8.5:1 or 9:1, which is lower than 10!!!!!! Link to post Share on other sites

tyranneous 0 Posted October 2, 2010 Report Share Posted October 2, 2010 Lowering the compression ratio is purely to prevent detonation' date=' but is now a legacy of old technology [/quote']I believe you said lowering. You've gotta start somewhere to go lower anyway. Semantics, possibly, but you're still wrong. It also kinda points that it's not a legacy of old technology - otherwise TFSI wouldn't be lower than NA FSI, would it?Calico - I've been around a while, and I know people on the face-to-face network. First post on here, that's true. I like to enter with a finally tuned 12.3:1, rather than a *BANG* or cracked exhaust manifold. I'd also like to point out that post count != knowledge. There's a fair few folk who seem to think otherwise. Link to post Share on other sites

Have you seen the advert?http://www.youtube.com/watch?v=YHAZhj1s4FElol im not surprised he missed the point dude. kev was simply saying that as engines have become more refined as far as the fueling and mapping side of things go the higher compression you can get away with without det. although 10.1 is lower than a FSI engine is pritty much the same as a standard VR6. and to run 20 psi though a standard VR6 most would think is madness Link to post Share on other sites
