How was Vegas? hoping to get there next year for around my 21st in September!
Morning Jim, Vegas is awesome as long as you spend no more that a week there I reckon. I think teh 4 days I went for is ideal as while its big, its not THAT big. I would plan a couple of resorts a day, start at one end and work down. Seeing rivers inside hotels and shopping centers that make the trafford centre look both small, and low budget is absoluitely incredible. The gambling is good too if thats your thing. oh, and you MUST jump off the stratosphere, its 900ft to the floor... what a buzz!
Anyway, back to topic, where were crossing keys is where you said you wouldnt go any bigger than a 14 exhaust cam, I don't understand, is that for a t34 spec or in general?
A 16+ CAN be a a good exhaust cam for example, that has, off the top of my head 1.5/6mm extra lift, similar on the duration maybe a couple of degrees extra.
In my (limited) experience, cam timing plays a big role and can make, or break a cam. I believe people slating bd14s don't release its full potential and can make it seem at fault making a laggy engine.
All IMO
Ah, got ya. My answer is in direct relation to this topic as the OP is asking about a T34 engine. Lift isnt the problem in the exhaust cycle, its duration, and specifically overlap. I asked you to clarify "bigger" as most readers will assume that the YB BD range of cams all get wider and taller as the numbers rise and thats not true, the 10/14/15/16/16+ etc are just part numbers really.
