SupraHuman Posted June 13, 2010 Share Posted June 13, 2010 Seeing as a few members now put GSC cams in their cars (myself included) here is an interesting read on SF regarding the 3 cams tested in the same car on the same dyno http://supraforums.com/forum/showthread.php?t=533317 Quote Link to comment Share on other sites More sharing options...
JamieP Posted June 13, 2010 Share Posted June 13, 2010 You have to be a member to see that, GSC cams rock but are hard to get at the moment i hear. 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 http://gscdownloads.com/2JZ-Camtest/HKS272_S1_HP.jpg HKS 272 (Green) vs GSC S1 (red) TQ Only http://gscdownloads.com/2JZ-Camtest/HKS272_S1_TQ.jpg HKS 272 VS GSC S2: HKS 272 (Green) vs GSC S2 (Blue) HP Only http://gscdownloads.com/2JZ-Camtest/HKS272_S2_HP.jpg HKS 272 (Green) vs GSC S2 (Blue) TQ Only http://gscdownloads.com/2JZ-Camtest/HKS272_S2_TQ.jpg GSC S1 VS GSC S2: GSC S1 (red) vs GSC S2 (Blue) HP Only http://gscdownloads.com/2JZ-Camtest/S1_S2_HP.jpg GSC S1 (red) vs GSC S2 (Blue) TQ Only http://gscdownloads.com/2JZ-Camtest/S1_S2_TQ.jpg All Three Together: GSC S1 (red) vs GSC S2 (Blue) vs HKS 272 (Green) HP Only http://gscdownloads.com/2JZ-Camtest/S1_S2_HKS272_HP.jpg GSC S1 (red) vs GSC S2 (Blue) vs HKS 272 (Green) TQ Only http://gscdownloads.com/2JZ-Camtest/S1_S2_HKS272_TQ.jpg Quote Link to comment Share on other sites More sharing options...

JamieP Posted June 13, 2010 Share Posted June 13, 2010 I got mine from MVP in a few days JP, what? are they running low on stock?? I did the same, ricky49 called up and Dusty said nowhere has them at the moment. Quote Link to comment Share on other sites More sharing options...
Jamesy Posted June 13, 2010 Share Posted June 13, 2010 I spoke to Dusty and GSC cams are sold out worldwide til Aug. Worked out a treat for me as ive got the SRD stage 2 cams going in Quote Link to comment Share on other sites More sharing options...
JamieP Posted June 13, 2010 Share Posted June 13, 2010 Yeah, i would go with the SRD cams aswell tbh, im going to go with Lee's 280's over the winter. Quote Link to comment Share on other sites More sharing options...
Jamesy Posted June 13, 2010 Share Posted June 13, 2010 He can custom make u a bonkers set mate!! Ive gone with the 269, 9.9 lift. Lee will be able to do something a bit special for the 'proper' big boys which should suit yours. Quote Link to comment Share on other sites More sharing options...
SupraHuman Posted June 13, 2010 Author Share Posted June 13, 2010 Yeah, i would go with the SRD cams aswell tbh, im going to go with Lee's 280's over the winter. What's the difference?? Have they been tested Vs GSC or HKS, or are they new to the marked? Why SRD cams over GSC? Price or support for Lee? Quote Link to comment Share on other sites More sharing options...
JamieP Posted June 13, 2010 Share Posted June 13, 2010 What's the difference?? Have they been tested Vs GSC or HKS, or are they new to the marked? Why SRD cams over GSC? Price or support for Lee? They are similar spec as the GSC cams, cheaper, and in the UK with good customer support. SRD is opening its own traders section soon and all his products will be reveled.

Wez Posted June 13, 2010 Share Posted June 13, 2010 Looks like the stage 1 cams are better than the stage 2s Quote Link to comment Share on other sites More sharing options...
JamieP Posted June 13, 2010 Share Posted June 13, 2010 Looks like the stage 1 cams are better than the stage 2s On a 67mm turbo they are, on a bigger turbo and higher rev limit i think the results would be different. Quote Link to comment Share on other sites More sharing options...
Lee P Posted June 13, 2010 Share Posted June 13, 2010 My stage 2 cams will be very similar to the GSC stage 1, 269 with 9.6mm lift. The reason the GSC are out of stock is that they are made with the crower blanks which will take 4 -6 weeks to get sorted. I have the same problem as my blanks come from the same place. I have enough for 4 sets of cams after that I have to wait the same as GSC. Quote Link to comment Share on other sites More sharing options...
Guest nickevo Posted November 19, 2010 Share Posted November 19, 2010 Hi New to here and thought id post something vaguely useful? as theres a few references to the GSC cams and struggling to get hold of them, they do have a uk distributor in northampton, Track Tek ive run them on my evo for time and have a good following in that crowd if its of any use? cheers Quote Link to comment Share on other sites More sharing options...
