S52 Cam Details?

[BlackHawkRacing]

Does anyone have a cam card for the OEM S52 cams?

Thus far I have:

• Intake Duration: 252º
• Intake Lift: 10.2mm
  
• Exhaust Duration: 244º
• Exhaust Lift: 10.2mm

I am looking for:

• Lobe separation
  
• Intake Centerline *
• Intake Open *
• Intake Close *
  
• Exhast Centerline*
• Exhaust Open*
• Exhaust Close *
• Bonus * for injector events

I don't need all those things, as you can calculate some with others, but this is the wish list.

Wonder if Mino at Acihlles has the info you need?

You could also try sending Someguy2800 a PM. He posts mostly in the Forced Induction subforum but knows a tremendous amount about cams for these motors.

I thought about that but didn't want to bother anyone I wasn't going to spend money with.

Thanks! Will shoot him a PM.

Mino is playing the long game. He's told me several times, "Call if you have any questions, you don't have to buy anything".

Agree he is very kind! Met him briefly at NJMP last month. A buddy bought an IP car Mino built and he happened to be at NJMP with a client that day.

Got the cam details from SomeGuy; very appreciative of his help. Here they are in case anyone needs them in the future:

Intake
10.3mm lift
253 duration @ 0.1mm lift
218 duration @ 1mm lift
centerline: 122 degrees
intake open time: 1 deg BTDC (measured at 0.1mm lift)
intake closing time: 72 deg ABDC

Exhaust
9.7mm lift
240 duration @ 0.1mm lift
205 duration @ 1mm lift
centerline: 113 deg
exhaust open: 50 deg BBDC
exhaust closing: 6 deg ATDC

that would be a lobe seperation angle of 117.5 with vanos off and 105 with vanos on
