I've got a chance to get a set of used Buddy Club Spec 3+ cams. Since I'm planning going turbo, I'm curious if these cams will work well in a turbo motor?

Knowing that ITR cams kicks *** in a turbo motor, one would think the BC3+ cams would as well since the specs are pretty similiar except for more duration.

Here are the specs for both cams:

BC3+:
Intake:
Duration: 296
Lift: 11.4mm

Exhaust:
Duration: 290
Lift: 11.8mm

ITR:
Intake:
Duration: 240
Lift: 11.5mm

Exhaust:
Duration: 235
Lift: 10.5mm

The motor I'm going to use is a stock ITR motor with forged 9.0:1 pistons and forged rods.

So what do you think, are the BC3+ cams worth getting over ITR cams on a FI motor?

The itr cams r proven to work, just keep them.
Its nice to see another fellow euro itr owner going turbo

I would just stick with the ITR cams, the buddy club stage 3 are just to aggressive for daily driving, and are a pain in the *** to tune them correctly. ITR FTW!!!!!

maybe for a turbo car the bc3s are too agressive, but on a friends n/a car they idled just like stock

Longer duration is NOT what you want on a boosted motor.

how high are you planning to rev the motor and what do you plan to use it for. with the longer duration, you will lose the mid range, but if you are willin to rev it high enough you should see the gain there.

The BC3+ are very mild cams. Bearly more agressive than ITR cams. They're actually made for daily driving. If you look at the specs the intake cam actually has less lift than the ITR cams.

In a NA engine the BC3+ make more midrange torque than the ITR cams, and just about the same topend. That would be ideal in FI motor as well.

So why would more duration loose midrange in a FI motor?

i remember a post awhile back where someone tested an FI specific cam with lower than stock duration vs a regular vtec cam. the vtec cam made more power on top. but did lose in the middle. i was basing my statement on that.

The BC 3 cams will work and produce more power depending on rev range and also VE of the engine, and turbo size.

If your going very wild with a large frame turbo, good head work, etc...It will help be you have to realize it has to be a puzzle put together either wild or mild. Can't have wild cams in at 10psi of boost and a 8500rpm limit.

End of Story BC 3 cams will produce more power then the ITR cams providing conditions are the right ones for the cams.
