With proper tuning is there more power on table with upgraded cams on the stock blower…
I have a contact at Comp Cam who can possibly make something up- would just have to get GIAC to do some tuning…
Discuss.
I helped a friend put a lumpy cam in his AMC 304 V8 in his 72 International scout. We then cut out the wheel wells with a torch and put 40 inch tires on it. When we tried to spin the wheels on the pavement, we twisted up the driveline like it was a rag we were twisting to wring the water out of.
That’s the extent of my cam upgrade knowledge.

Ya that’s what I was thinking too.
Wouldn’t it be more economical to wait for APR stage 3?
By the time you find/build a cam, get a tune, etc…the new Eaton blower will be ready to install.
Wouldn’t this also require upgraded rods and pistons?
A proper cam realistically shouldn’t cost more than 3-400 dollars and if tuned properly we can probably see 40-50whp gains and an even better powerband.
Upgraded cams won’t need pistons or rods.
i remember back in the day when shrick made those cams for the b6/7 s4, they were an arm and leg to buy yet there was no available tuning to gain anything from them, they were a few grand
yeah 4 cams for a small market isn’t going to be cheap. Shrick cams were about $2000 for the set. plus you should consider if the rest of the components in the heads handle the extra lift/duration? the gains may not be that great on a stock blower either, too much duration and you may loose power (poor cylinder filling, see early APR RS4 blower kit’s tuning). I’d agree it’d be best to address the issue when it becomes a limitation, such as with a larger blower.
shouldn’t need to touch the bottom end though as long as interference doesnt become a concern.
Not sure I have ever seen a set of Cams that were $400. Even a cheap set for a WRX EJ20 start at $600, and there are a million of those engines around.
cams for domestic pushrod V8s will go for around that much
You are right, I meant to say for anything (but domestics).
Yea, but that’s for 1 cam. We have 4. Expect at least $1000-$1200 and probably more for an upgrade if it ever happens.
If anyone knows that, it’s beemercer. He was just pointing out notarmed’s blanketed comment that he has never seen cams for $400.
ok
OK
ok
Whattttttttt???
YEAHHH
I only heard about that guy from Chapelle’s show.
To that end, I have just recently cued up every episode of Chapelle’s show and will watch it in a marathon over the next couple of weeks. So good.
