Cam question

Cam spec  at  .050  280/300  adv du  313/340  .750 lift.   112 lobe sep .would this cam work in  a twin turbo  aplication...9-1 compression race fuel?thanks.

What type of turbos are you using

way too big. Lift is fine. duration is crazy.

Turbo engines run faster (at the track) when you open the exhaust valve sooner. With short intake duration, the engine responds with speed at the track. By opening the exhaust valve sooner with either a tighter lobe-separation angle or long exhaust duration, the engine generally responds better. You will lose scavenge if you open the exhaust valve too late.

Yea, I kind of thought that may be too big .i I also have another cam  .640 lift  duration  at .050. Is 270/276  adv  dur 310/314  108 lobe sep.would that work?  The turbos are 77mm

With what you have that would be a starting cam but if you had the funds I would give a call to your choice of cam guys and let them cut a cam to your app it would be ALOT better than a OTS cam

It is better on the duration and lobe separation sides but now the lift is probably too low for your heads depending on how they are finished out.

Your best bet is to get a custom cam. It is the heart of the motor so you can't just get by. The cam is probably more important to a turbo motor than the heads.

Thanks fo the reminder.
