just asking a question

well i bought a 96 gsr the other day and the owner was telling me it had double vtec..i didnt really believe it untill well i tried it myself and it does..vtec kicks around 4500ish and then agian 6300ish rpm could sum one explain

[silversol]

its only hitting vtec once. the stock gsr manafolds have a dual butterflys that work off vacume and open at a higher rpm. so it could feel like its hitting twice
