CharlieG101 Posted January 24, 2019 Report Share Posted January 24, 2019 Hi There, My VW Lupo 1.4s seems to have a rev protector on it, it revs to 6000, then cut seems to fall off and then rev back up but doesn't bounce on the limiter, Any ideas on how to remove it?

mk2 Posted January 24, 2019 Report Share Posted January 24, 2019 (edited) Hi, welcome to club lupo. All electronic controlled engines have rev limiters, which stop the components being stressed beyond their design limit. Some engines have clever variable rev limiters (lower limits when engine is cold scenario for example). No point removing it unless you change mechanical stuff. At wide open throttle, the speed it takes to burn the mix will be slower than the revs. So you reach a point when the mix wont have enough time to burn so power drops at high revs. The mix simply burns as it leaves the cylinder. If the compression ratio is increased or cylinder size reduced then it's worth upping the revs. Google V8 2L engines, or high cylinder count low capacity engines...

CharlieG101 Posted January 24, 2019 Author Report Share Posted January 24, 2019 It has a rev limiter however it stops it revvving at 6000, and lupos normally rev to 7000+, so when accelerating in lower gears I can get the full potential out of the engine, the regs seem to fall off and it doesn’t continue to rev it falls to about 5000 Quote Link to comment Share on other sites More sharing options...
mk2 Posted January 24, 2019 Report Share Posted January 24, 2019 You're just reaching the power limit... normal. Quote Link to comment Share on other sites More sharing options...
Sausage Posted January 24, 2019 Report Share Posted January 24, 2019 Peak torque is at 3800, peak power is at 5000 on the 75hp 16v if it is in good condition, there really is no reason to go much beyond that apart from to rev the nuts off it, they dont rev to 7k either.
