boldy205 74 Posted July 18, 2018 Hi, I have a Gti6 with a low boost Lynx Rotrex kit. I find the throttle response some what delayed, as in if I heel toe to down shift for a corner it takes a good stab at the throttle to get the revs up, very different from the previous non blown set up with carbs. I have the same delay if I rev the engine at the throttle body (therefore cancelling out the throttle pedal) Is this something this set up does, because if the long intake route between throttle body and actual engine? Thanks! Matt Share this post Link to post Share on other sites
James_K 6 1 Cars Posted July 18, 2018 I have a rotrex charged gti6 and have never noticed a delay on mine. I suppose intercooler pipework length might be a factor. My intercooler is mounted high up and very close to the charger, couldn't get any shorter distance. Share this post Link to post Share on other sites
Daxed 7 Posted July 18, 2018 Mine is charged. Had a low rpm flatspot with a mech only VSS. Dual output VSS to Ecu solved the issue. Share this post Link to post Share on other sites

j_turnell 134 3 Cars Posted July 19, 2018 I run the same setup, not noticed a delay, but its certainly not as sharp as when it was on bodies. I'm moving my TB to the end of the inlet. Share this post Link to post Share on other sites
boldy205 74 Posted July 19, 2018 I'd guess it's not the VSS, as its not a flat spot as such, more just a delay. As stated I guess it's just a fact tha the intake length is so long now. Do more advances set ups have the throttle body nearer the intake manifold? Thanks Matt Share this post Link to post Share on other sites

j_turnell 134 3 Cars Posted July 19, 2018 Yeah, quite a few run it this way, just means you need a dump valve or alike. I run a ttv flywheel on mine also so it still picks up quickly. I don't like the friction fit on the end of the charger so looking to change and tig the ally adapter onto the inlet and then bung the filter straight onto the charger.

Thanks Matt They do yes, I’m not sure the standard management is capable of running it with the throttle body on the inlet though, hence it’s where it is in the first place.

boldy205 74 Posted July 20, 2018 Ah, right, I guess it's that the TB will get confused as its going to be seeing positive pressure if Its on the intake manifold. Share this post Link to post Share on other sites
welshpug 1,622 Posted July 20, 2018 throttle body wont but the original ecu and map sensor dont read boost, only vacuum. Share this post Link to post Share on other sites
