VR6 Man 0 Posted December 10, 2003 Report Share Posted December 10, 2003 just fitted a shrick manifold but the engine is pinking 4000rpm, already got a superchip do i need to remap buy new chip or what help please . Link to post Share on other sites
VR6Pete 1,455 Posted December 10, 2003 Report Share Posted December 10, 2003 yes, u need to remap the ECU after you have fitted the shrick manifold. Link to post Share on other sites
binliner 0 Posted December 10, 2003 Report Share Posted December 10, 2003 yep take it somewhere like stealth racing and get them to set it up on the rolling road Link to post Share on other sites
VR6 Man 0 Posted December 10, 2003 Author Report Share Posted December 10, 2003 ok but can i remap my superchip or do i have to buy a new one Link to post Share on other sites
VR6Pete 1,455 Posted December 10, 2003 Report Share Posted December 10, 2003 didnt mart say he got his re-mapped? im sure u can! give stealth a buzz they will be able to tell u Link to post Share on other sites
binliner 0 Posted December 10, 2003 Report Share Posted December 10, 2003 no im pretty sure superchips arent remappable but I could be wrong... as Pete said phone stealth or AmD and they'll sort you out Link to post Share on other sites
tommy 0 Posted December 10, 2003 Report Share Posted December 10, 2003 99.9% sure that Superchips aren't remappable.....they're on off the shelf chip Link to post Share on other sites
K9ANY 0 Posted December 10, 2003 Report Share Posted December 10, 2003 VR6 Man there is no point of getting the VSR fitted without a total custom remap for your car as you will need a switching point at around 4000rpm to adjust timing and fueling.My advice.....throw ure superchip away they are shite!....take a trip down to amd and they will sort it.....i think it will cost you £250 for a custom remap.Basically:The VSR manifold can be fitted to both 2.8 and 2.9 litre engines. Eventhough the VSR achieves similar aims to Audi?s switching inlet manifold, the operating principle is different. Two diverse technologies are applied in the VSR. It is designed so that at low engine speeds, resonance is used to improve cylinder-charging efficiency. At higher RPM, oscillation-tuned, individual, broad tracts are used. Switching from one to the other is achieved by single flap, also vacuum operated at 4000 RPM. The tuned inlet tract operates by the low pressure caused between the throttle valve and the inlet valve, by suction of the descending piston. Through inertia of the air in the tract, the airflow tends to keep moving towards the inlet, even after its closed, causing a slight over-pressure when the inlet valve next opens. This ensures high charge efficiency even during early stages of the induction stroke. Further during the same stroke, inlet pressure falls followed by high pressure but not before the inlet valve closes. In order to achieve optimal control of the oscillation and reflection of the column of air in the inlet tract, it needs to be closely co-ordinated with valve timing, but this is not possible due to variation in the engine speed. Even at mid-range-rpm, the valve opening and they are out of synch. The second pressure wave arrives much too early before the inlet valve closes and a backflow reduces fuel efficiency. Now to achieve high torque under these conditions, resonance-fuel is utilized. This is achieved by closing the connection flap between a small resonance chambers immediately before short inlet tracts above the inlet valves. These transforms the 6-cylinder engine into effectively two 3-cylinder engines with uniform firing times, which do not have overlapping inlet strokes. A resonance pulse of up to 6psi (0.4bar) above atmospheric is achieved, leading to remarkable fuel efficiency and torque increases. On the roadThe effect of the manifold is immediately apparent ? you won?t need any test equipment! A new urge is sensed almost right from the idle. There is markedly better acceleration up to 4,000rpm, followed by a strong surge to the redline. The switchover of the flap is almost undetectable from inside the car. The new low to mid-range power is particularly useful in the higher gears. The 50-70 sprints in fourth is reduced by almost a second! Fuel consumption is also improved, as higher revs don?t need to be used as much.www.club-vr6.co.uk[ Edited Thu Dec 11 2003, 06:58PM ] Link to post Share on other sites
mina 0 Posted December 10, 2003 Report Share Posted December 10, 2003 Those words look very familiar....knew I should have copyrighted them!! Link to post Share on other sites
mina 0 Posted December 10, 2003 Report Share Posted December 10, 2003 Seriously though, VW almost did fit it as standard on the Mk3 - it was on the Mk4!! I still reckon it's one of the best mods u can make to a VR Link to post Share on other sites

Guest artay Posted March 3, 2004 Report Share Posted March 3, 2004 can the VSR be coupled with a supercharger ?? Link to post Share on other sites
