Both Jun 3's, but hope this helps.

thanks for the links.....does anyone have any sheets or links to threads with any of the cams dyno'ed/baselined on the same motor?

 

i'm gonna go out on a limb and say the Toda C's will net the most overall power.

i'm pretty sure the buddy club 4's have the same vtec lobe as the Toda C's...not sure about the primaries.

as for comparison sheets..don't have any
just thought i'd share. k bye.

 

BC4/S2S2/Jun3 all have same vtec lobe. Toda C's are 300/12.5

It was something like that, I can't really remember. Are you doing a K in your car man??

you are correct but also please note the smaller duration they ahve though

Toda Spec C 12.5 mm, duration - 255 @ 1mm 12.5 mm, duration - 255 @ 1mm
Jun Type 3 12.0 mm, duration - 265.3 @ 1mm 11.5 mm, duration - 265.3 @ 1mm


I say Jeremy go at least with the Spec IV's , but Id personally go with the V's
Buddy Club IV 12.3mm, duration 306@1mm 11.8mm, duration-302@1mm
Buddy Club V 12.8mm, duration 312@1mm 11.8mm, duartion- 306@1mm

 

thanks guys...anyone have dyno sheets to compare?

 

I might have an extra set of brand new Jun3's.

The BC5's will bleed off too much compression for a 12:1 motor. He will have a broader powerband, including more peak, if he went with the BC4's versus the BC5's.

I am running BC5's temporarily as a tester, and I have roughly 12.3:1 static, these cams are limited on my motor to just over 3degrees advanced/retard before there is piston to valve contact, the duration is so big it drastically limits the ability to tune out the overlap. Might as well start with a cam that will allow more adjustability, and is more appropriately sized for his compression.
