Nathan_M Posted April 3, 2013 Share Posted April 3, 2013 You should have saved up a bit more and brought an ST if you want snap crackle and pop. Haha. Quote Link to comment Share on other sites More sharing options...
cuke Posted April 3, 2013 Share Posted April 3, 2013 Hi, if it's a 125ps then a remap would be far better... 1 Quote Link to comment Share on other sites More sharing options...
b1g_dav3 Posted April 3, 2013 Share Posted April 3, 2013 Any valve will be fine, but it won't add performance. Quote Link to comment Share on other sites More sharing options...
jd_james Posted April 3, 2013 Share Posted April 3, 2013 A dump valve just knackers your car up if it isnt done right.. You're asking for loss of power! 1 Quote Link to comment Share on other sites More sharing options...

Lenny Posted April 3, 2013 Share Posted April 3, 2013 +1 Fit a saber EDV (electronic dump valve) http://www.ebay.co.uk/itm/Saber-XL-edv-V3-Dump-Valve-Simulator-Sound-/150840059948?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item231ec4a82c Your turbo won't produce enough boost to generate a loud enough blow off from your engine. So the electronic is the next best thing lol atleast yo can switch it off after a week or two when the novelty wears off. 1 Quote Link to comment Share on other sites More sharing options...
WeeJohn125 Posted April 3, 2013 Author Share Posted April 3, 2013 Thanks for all the help ;p it's sounds more of a hassle for not much gain other than a noise :p Thanks John :) 1 Quote Link to comment Share on other sites More sharing options...
FOCA Posted April 3, 2013 Share Posted April 3, 2013 Thanks for all the help ;p it's sounds more of a hassle for not much gain other than a noise :P Thanks John :) Most of the people that fit them do so because of the noise - they want their road-going boy racer Subaroo etc to sound like a rally car They were originally fitted to race/ wally cars to improve throttle response after a gearchange, because of the air "hitting" the throttle butterflie/s the air flow can "stall" and "bounce back" even causing the compressor to "flutter"/ slow down with the dump valve (properly fitted/ set up) on a gearchange when the butterflie/s close instead of the air in the boost pipes "stopping" it gets "dumped" out of the dump valve so the momentum of the air continues to flow and the compressor continues to spin, so when the throttle is opened again (after a gearchange) more boost is available sooner (less lag) - this only applies to turbo cars with throttle butterflies - ie petrol turbo Modern turbo engines have sophisticated systems under the control of the ECU, some of these "recirculate" the boost so it is not wasted (better for economy) or the dump valve is internal and quiet I have 2 dump valves on mine - 1 when i lift off/ change gear the air is released from the actuator, so the wastegate is (always) shut when i come back on the power so the turbo spools quicker, improving throttle response after lifting off/ changing gear (it works in a similar way to a petrol turbo dump valve, though it does not "hiss", it "dumps" the air out of the actuator, it could be described as an "ant- lag" system) 2 an adjustable mechanical dump/ blow off valve is connected to vent the air pressure from the inlet manifold, if it goes above a certain level, so if the boost control systems fail, (including the wastegate/ actuator etc) or i turn my electronic boost controller too high, or the boost "spikes" it will "dump" the exess pressure, this is more of a "safety device" and could work on any turbo car, though it does "dump" air out of the inlet manifold - this hisses if it opens but is more of a constant hss than a "pssht" 2 Quote Link to comment Share on other sites More sharing options...
