Van Bill van Badger5:

There are 2 main types of throttle body, DCOE pattern sidedraft types which require an additional inlet manifold, and Direct to Head throttles (DTH). We favour the DTH ones as the installation is simpler, lighter, more direct and less restrctive. -Open the throttles and say hello to the valves. DTH throttles will work out slightly less expensive when compared to DCOE ones + manifold. Both systems work pretty well, and give very similar results. Some tuners would argue DTH throttles won't work as they're too short an induction track, but facts and an existing happy customer base, with dyno's proves they do provide significant gains. Personally I would say they're marginally better on top end being the more direct product, but the differences are very small. Either way, we supply both types so have no axe to grind either way. (we did help complete the development of the DTH bodies tho )


Conclusie: DTH is de simpeler uitvoering en als je niet van plan bent een 250 pk rallymonster te bouwen waarschijnlijk de beste/makkelijkste/goedkoopste keus.
