bigpants baby 0 Posted July 5, 2004 had me z engineering s/c on my vr for about 2mths now,everything is running fine,but i cant change gear properly(on changing gear the revs dont drop that quick so you change gear still at high revs) my question being would some kind of dump valve help?if so what kind? recirc or just a std piston vent to air dump valve?

corradovr6sc 0 Posted July 5, 2004 yes, a dump valve is good as it prevents air from travelling in the opposite direction in which the charger is blowing so when you get back on the throttle it boosts quicker. You can use an atmospheric dump valve between the maf and the charger. Quote Share this post Link to post Share on other sites
