Engine Shops? Engine Specs?

[Whytiptoe]

Does any know of a shop or just know what some of the specs are on the 3.3? Wanting to know what the cams are and if they know what the heads CFM is.

No one has disassemble the head yet to gas flow them, so doubt you'll find anything without doing it yourself. The Intake ports look great. Very high quality casting, with little to no shrouding of the valve. Exhaust side is an internal manifold to the head, so trying to get true CFM will be impossible, and traditional porting is impossible. The only option would be to try and extrude hone it with some custom fixtures. Probably not worth the cost.

On the cam side, these are CVVT Intermediate lock cams. Mechanically, they can be retarded as much as 30 degrees, and advanced as much as 55 degrees. Unless your going to replace the entire complex CVVT system, and then figure out how to tune, aftermarket cams probably a no go. Not really needed anyhow, as the CVVT provides unlimited duration/Overlap tuning ( if you have access to the right tables) , and turbo cars don't need high lift cams due to the FI.

Bottom line, If you are looking for power in the heads, move on as not much to be had.

Do you know anyone who is actually playing around with the timing yet? This is more of a curiosity thing than anything else at this point in time.

The only tuner I know of is tork. And I don't know much so take that as is.

Not as far as I know. The CVVT tables are not being modified by any of the tuners thus far.

Tork and a couple ECU tuners are slightly adjusting ignition timing, but not valve timing like they are discussing.

Anyone know what the CFM are of the stock turbos?
