Im planning my next set of upgrades on my sc and I was doing a little research on the AP1 intake cam and how it theoretically can increase your power up top.
But I also heard from Sideways that it could also increase swirl in the cylinders which means more chance for detonation.
But I didnt find anyone that has accually done it yet!
Has anyone done it?
If so did you also go with upgraded springs, valves, and retainers?
Are the upgraded springs valves, and retainers necessary in this case?

Thanks!

 

I'm pretty sure Jimboner did this mod not too long ago. I never heard how it turned out.

IIRC the whole AP1 cam thing came from a spec error on BC's website. Also I've heard that AP2 cams are better for FI.

 

theres a thread somewhere that has all the specs of both ap1 and ap2 intake/exhaust cams. honestly, there so close in spec i wouldnt waste my time.

more boost is way easier and will yeild more power. i wouldnt mess with anything else until your over 14psi

 

I believe BlackTrax has an AP1 intake cam on his AP2 (w/KraftWerk$ kit).

 

this is discussed in the N/A forum. A few ppl have done it, with marginal gains.

 

well thats part of my next step and I wanted to see if an ap1 intake cam would be a good compliment to it.

 

i doubt that it would hurt to use the ap1 cams. Talk to jimboner, I sold him my intake cam for this purpose, but not sure if he is N/A or FI.

 

Here this should help, but you will not find anyone doing back to back dyno's with different cams.

It looks like the ap1 cam is a good option for turbo guys with tubular manifolds but what about supercharged guys?

 

The combo works well
