Anybody has tried out the Buddyclub spec 6 cams. How's the power delivery compared to the spec 5. I ran a spec 5 in my EK9 race car and it has nice smooth power delivery all the way to 9000rpm. The spec 6 has a longer duration but a lower lift. How does this affects power delivery. Thanks!

 

I didn't even know they had a spec 6. How much compression were you running with th espec 5's?

 

9k.. thats all you rev up too?

 

From the BC website

RACING SPEC VI EXTREME CAMSHAFTS

1.Must use buddy club valve spring
2.Must use buddy club cam gear

4.Can use standard valve or oversize valve
5.Smooth idle
6.Good torque
7.No valve clearance noise
8.Easy computer mapping and setting
9.Good re-acceleration response ( will not have knocking problem as

I have tested 3+ & IV & V but not VI yet going by my testing you will need 13+ to 1 compression very good flowing head and a 2lt engine with good boltons to support these cams.

trust me wait a couple of months for the buddyclub spec 7+.

it's gonna be unreal.

 

I'm running a 13.5 compression ratio B20B, fully ported head, crower valve, toda valve spring, wiseco 85mm piston, eagle titanium 5.394 rod, balanced crankshaft

 

i hope u dont plan on streeting this motor but i have a buddy that is using the bc6's in his bored and stroked gsr and hes pullin 10.6 in a hatch. the bc6's are harsh i hope u have some thing that will correct the idle because ur not gonna idle its gonna bounce between 1000 and 2300 lol. his setup is 85mm pistons 95mm stroke with 14:1 comp ratio he makes serious power with them.

God I hope not...

 

in reality is not so hotness... in regular engines... 1.8 liters etc well i think the cam was quite large. it was comparable to a pro1... maybe a pro2, but the engine never had pro2's so i cant say. Maybe it was just a bad cam for a 1.8, maybe it wasn't even the cams they where claimed, since i didn't bought them. If i have time to find them i'll post the dyno graphs, if i can find them.
