It seems like an ok turbo cam. Most will say go with reverse split, but I think the jury is still out on that one since many successful turbo engines exists with straight pattern cams. I think you would benifit with a little more LSA though like at least 114.

Just remember, lope + turbo = power left on the table. That cam looks pretty good, but if you can, get it as close to 0* overlap as possible. 8* is better than 30*, but it's still 8* "too much".
Also keep in mind that the cam will have less impact than on an NA motor. If you're going to have a max effort turbo setup with really really low backpressure, a forward split works great. If you have lots of back pressure, though (e.g. you care at all about spooling up in a reasonable amount of time), a reverse split is better. A single pattern fits nicely somewhere in between.

whats not being taken into account is with a big single your going to have alot of back pressure in the exhaust ... The more you have the faster it will spool the turbo.. most people that can keep the back pressure below a 1:1 ratio have been able to run the strait up splits with twins or really good flowing turbos/exhaust... You just taylor the camshaft to the engine/application... I also have been going a TON of research on my own camshaft for a turbo 408.. I dont think its a huge deal.. thats a huge cam for a turbo ride !!... biggest i had seen dyno proven was 238/242 and it made 1000rwhp with a 91mm turbo .... I am not looking to reinvent the wheel.. I just been looking to see what everyone has used and try and map out there combo to my own and think about weight,turbo size,motor.. stall... Everyone I have tried to talk with are really great and seem to express intrest in other projects as well as Share what they might do different on there own rides if they had it to do again ...
