Camshaft test GSC S1 and S2 vs HKS 272

Camshaft test GSC S1 and S2 vs HKS 272

Test Mule:
94 6spd mkiv
stock long block 2JZGTE
stock intake manifold
GSC Single Spring Valve Spring using stock retainers
Titan Cam Gears
Precision 67MM Turbo .81 Exhaust housing (Journal Bearing)
HKS Header and 50mm Wastegate.
3” DP and Mid Pipe
Greddy 4 Row
AEM EMS with HKS DLI
HKS Ti 4" exhaust

Fuel:
C12 (same 10 Gallons was used for all testing)

Dyno:
DynoJet 224X 2wd dyno

Boost:
24psi tapering to 22psi (this was consistent with all the camshafts)

Timing and Fuel:
Timing was the same for all camshafts. i did not adjust the timing table I only verified the base timing off the crank and the AEM EMS after each cam install.
Fuel was set to 11.6AFR under boost and was consistent with all camshaft sets.
A new set of NGK 6097s which were gapped at .024” were installed for the test.

Degreeing in camshafts and Valve Clearance:
The HKS Camshafts call for a .008” intake and .010” exhaust clearance (this was set across the board correctly)
GSC camshafts use a looser clearance of .010”intake and .012” exhaust (this was set across the board correctly)

Each set of camshafts were degree’d to the manufactures specs exactly…
HKS 272: 114 Intake , 114 Exhaust
GSC S1: 107 Intake , 116 Exhaust
GSC S2: 110 Intake , 120 Exhaust

HKS 272 VS GSC S1:

HKS 272 (Green) vs GSC S1 (red) HP Only

HKS 272 (Green) vs GSC S1 (red) TQ Only

HKS 272 VS GSC S2:

HKS 272 (Green) vs GSC S2 (Blue) HP Only

HKS 272 (Green) vs GSC S2 (Blue) TQ Only

GSC S1 VS GSC S2:

GSC S1 (red) vs GSC S2 (Blue) HP Only

GSC S1 (red) vs GSC S2 (Blue) TQ Only

All Three Together:
GSC S1 (red) vs GSC S2 (Blue) vs HKS 272 (Green) HP Only

GSC S1 (red) vs GSC S2 (Blue) vs HKS 272 (Green) TQ Only
