Matching turbo to cam information

[michael evans]

Just like to know if you can get a range of Cams for a certain turbo ?

Mine works great to together now. I was wondering if in the future if I can change cams without changing the turbo.

I have a 212/212 duration cam with a 6768BB turbo.

Can I change if needed to ?

There is a lot more to a cam than duration @0.050. I am sure a cam can be replaced but a lot will depends on the goals and supporting parts like springs, converter, head flow, rocker/ratio, etc. Granted, all those parts can be replaced but posting the cam card specs and goals will provide more accurate feedback.

Bison has a special on cam/lifter combo and it wouldn't hurt to reach out to him as well

Agreed. A 212/212 cam is a good grind. You may need to look at other things.

I was just wondering what my turbo is matched or good for if you will.

I do like my 212/212.

i like the cam but the 68 ex wheel is oversized for it.that 68 is good for over a 1000hp.

What are your goals? A friend of mine went 10.1@132 on a flat tappet 212/212 and a 6466.

I have ran a 60-1 all the way up to a 6765 with the same 212/212 and had great results, many converter changes tho

Low 10s. Was told it will go quicker,but I doubt it.

You shold search for Grumpys Daughter's car. Her name is Melissa and she is the Queen of the TAI class. She went in the 9s with a 212/212 and a 66 or 67mm years ago.

you can but there are much better sppoling ex wheels than the 68 for a goal like that.

The 212/212 will go quicker than low 10s with the right combo.

Good info on overlap vs turbine size. A very critical aspect of matching a cam to a turbo.

Thanks but I am more interested in what turbo will go with my 212/212 cam since I am taking off the turbo for a rebuild this winter and have a fresh engine.

Do you have a cam card, I would match up a turbo that will work well based on that. So if you know what the overlap is, I would recommend matching a turbo with a turbine wheel size that matches the overlap vs turbine in the link that Bison posted. I think the link answers your original question.

Bison is the guy who can answer this for you!! Hopefully he’ll chime in.
