What are the specs on the GSR cams?
I want to see the difference (if any) between the prime lobes on the intake and exhaust cams on the GSR and ITR.
I can find the difference between the Vtec lobes easy and I have all the specs on the ITR cams.. But what are the GSR's?
Yes I've searched and I've found nothing.
And just in case you want to know..:

if you really wanna know...do the measurements yourself...the rocker ratio is 1.55 ...you can take it from there
keep in mind this information isnt very useful as if your intentions are performance orientated...the car doesnt spend much time on these profiles

There still in the car man.. And I seem to have lost the spare set I kept in my back pocket.
And I know 1st and 3rd lobes arent for performance, they're for daily driving and thats what I want to know about: Will the swap do anything to the gas mileage I get OUT of Vtec?
I've been searching and have come up with NADA
