Grilled Posted April 1, 2009 Share Posted April 1, 2009 I always come across these things on eBay always offering extra performance and better fuel ecomnomy, but are any of them safe and actually work? I bought a resister for like £5, never used it, gave it to my mate who put it in his nova, and it worked, but made the engine management light come on. A lot of people say that those just tend to blow your engine up as well. Also I've noticed the small fan like object that go inside your air intake pipes that apparently increase performance and brake, but yet have no idea what to think of that. Currently I've came across 'power boost valves' that vary from £12-£30.. then what appears to be a 'real' one for £100. I'm wondering if there's much difference in these two products. Cheap ebay item Not as cheap ebay item Expensive car performance item Question I'm really asking, do these really do anything, and if they do are there consequences?

sr-performance Posted April 2, 2009 Share Posted April 2, 2009 no, mate there no good, resistors only trick your engine into getting more fuel, and anything that fits inside your intake pipes cause a restriction so no they wont work either.. :) steve www.sr-performance.co.uk I always come across these things on ebay always offering extra performance and better fuel ecomnomy, but are any of them safe and actually work?I bought a resister for like £5, never used it, gave it to my mate who put it in his nova, and it worked, but made the engine management light come on.

squaddiefox Posted April 7, 2009 Share Posted April 7, 2009 those resistors only trick the ECU into thinking that your engine is running cold, therefore keeping the auto choke open, which overfuels the engine and can cause massive failures at worst, or poor running due to coked up spark plugs at best. i wouldn't waste money on those so-called performance mods. get it done properly by the professionals.
