Do aftermarket cams for s2k have same cam profiles pre-vtec? Will it drive exactly like stock cams say until 3k rpms and then switch over to very aggresive cam profile? Cant seem to find the answer. Oh and what size are stock s2k radiator fans? Beel looking for that info for days

Hatrick that is an incredible looking dyno graph, thank you for sharing!

So if this is the stock vs bc cam dyno this means the stock and bc cams have the exact idle and low rpm drivability but the bc cams are on v-tec plus steroids? This seems too good to be true

Where did you find that graph mate?

Did you play around with the cam timing on this or this is on stock cam gears?

What is the cam timing? Like pistons, turbo cams are different. More separation, less overlap.

Unfortunately I can't find anyone listing their K24 turbo cam specs accurately. However, the Kelford T-202C cam for the Supra, 228/232 at 1mm, lame 9.9mm lobe lift because the 31mm flat tappet buckets can't compete with Honda's roller rockers, has the exhaust centered on 116°BTDC and at 1mm at TDC. Intake is at 1mm at 7° BTDC. Less overlap. With dual VTC it would be programmed to overlap at no/low boost. For some reason Kelford isn't listing their K24 cams and GSC doesn't have any. However, an H22 has 108/115 centerline, 111.5 separation for turbo, 104/104 for NA.
