Which ratio rocker?

Yes, n/a. well of course it will flow more with boost. i was talking about a higher spring rate. i'm more worried about that thin oil film on the lobe of the cam shearing. i'm willing to sacrifice a little power for durability. well, if you can find 1.7, then do it. however, from what i understand, you want less lift on the exhaust side. somthing about velocity and getting the turbo to spool quicker. you certianly will have a ton of power with that combo, but i do believe there is a cam that is better suited for your turbo. i'd like to have a cam with a LSA of at least 114. I do think 112 will be ok for 6 lbs. any more and the valve overlap will allow the boost to blow through instead of fill the cylinder.

to give you (Syn) an idea.... there is a wagon (Steve's) that is completely stock with the exeption of a turbo cam 212/202, lift with 1.5 rockers .432/.417, LSA 114, ben's ported and polshed and gasket matched 3.1 heads, and 22lbs/hr injectors. everything else is stock. at the dyno he got 230@5400rpm, and 260 ft/lbs between 3100-4500 all at the wheels. ben was saying at 7 psi, he ran a 13.99 @ 105 MPH with clutch slippage all the way. on the shifts he had to let off so the clutch would grab and ease back into it. awesome for that set up!!

I ran that car to 13.90 and 13.91 @ 105 and 104 mph respectively just last month. both 2.2 60 foots. The clutch was not slipping at all, but that was with falken street tyres. This was on 11PSI of boost not 7psi. Still untuned too. Fucking pig rich.

When we ran the car last year with the shitty spec clutch It ran 14.0 at 101 ? Still was easing into the car to get a feel for it and take it easy to see what it wanted to do. After that run, #3 for the day the clutch was gave out when I launched hard and the rest of the day was shot, with only 14.4's-14.7's at 7psi with slipping clutch.

yeah, i remember either Ben or Curtis saying it still needs a little fine tuning. still pretty awesome for a budjet build!!
