Turbo Cam specs ?
Re: Turbo Cam specs ? what are your drivablity requirements?
emission requirements?
what do you want to redline to?
could start witha 224/220-115 and adjust from there.

Re: Turbo Cam specs ? Cam companies typically recommend more intake duration for turbocharged applications, and the opposite for supercharged setups.
I think one way to go at this, is to find verify where Harlan peaked, and then go from there... I think he picked at 6400 with his setup... 228/224//112... I'd verify that because I could see a setup like that peaking sooner. Also I would look at whether bigger turbos or other differences in setup will affect the peak. Maybe look at some NA dynos too. My blower should move my power peak up 500 rpms higher than where it would be NA. NA my motor would I think peak around 6400.

Re: Turbo Cam specs ? So if you shift at 6800 you want it to peak lower than that so say 6500?
I'd say no more than 237/230//115/+2, that might peak too high for you.... Maybe 230/224//115/+2.
My blower cam is 230/237//115/+2 from FMS and we will shift it around 7000-7200.

I figured the exhaust since there is such a restriction in the exhaust with the turbine housing. Thanks for the quick replies.
