GSC cams are in and I got it started and running. When I swapped in the cams I didn't want to wait for OEM cam seals to arrive so I used a set from a parts store. I thought Fel-Pro would be able to handle cam seals. I was wrong.
Night before tuning appointment I noticed a little bit of oil on exhaust cam gear. Thought maybe I messed up the VC gasket instal (that WAS OEM) so redid it. Cleaned it up and went to get tuned next morning. On the dyno the tuner noticed oil pouring onto the roller (hadn't even done a pull yet!) so we pulled it off the dyno and checked out under the hood. Sure enough the oil was back on the cam gear and the TBelt end of the block was covered with oil. Got it home, took it apart, and here is what I found:
Amazingly the timing belt had no oil on it. I will still be replacing it soon, probably at 1000 when I switch oil and check the valve lash.
Keep in mind I have done many cam seals (all OEM) and never had an issue. I also made sure to use a bit of grease on the cam and was careful pushing the seals on. These seals had less than 30 miles on them and obviously no hard use. Worth nothing the intake seal wasn't ruined in any way but it was still leaking. All the caps were torqued properly so I think the only answer is the seals are of poor quality.
New OEM seals are in and the car is ready to go. I did make a slight change to the wastegate. I now have a .6 bar spring in there instead of the .5 bar. I realize it is a small change but this should allow me to maintain the boost by gear control in lower gears (aided by traction control once I install that) while allowing for a little more pressure up top.
I want to switch to these cams how is the spool compared the old ones
(itr correct)
Over all you are happy with these?
I had S2 Tuner 1s. These cams def spool earlier. We had to add so much timing we were wondering if I had didn't have them at 0,0. We verified with a timing light (again! lol).
I did lose 10ft/lb from the previous tune but I think this is due to the weather. It was a lot cooler last time I was on the dyno. The car feels like it pulls harder and it just wants to rev now. Tuner 1s started to fall flat over 8k or so and these just want to keep going.
TC has not been installed yet. That's my next project lol.
How much timing you had to end up running on the new setup
Old tune timing was 17 degrees at full boost (22 psi) in the same columns it is now 23 degrees. lol
Before the tuner advanced timing he tried pulling 2 degrees on the top end and the car lost 50whp! That was the point when we decided we needed to add timing.

Nice. Did u overlay the s2t1 cams dyno to the gsc cam? I just put in s2t1 cams from stock cams (gsr) and the gains were pretty good. ... 460whp with gsrs to 493 with s2t1 cams at around ~17psi

We did, there was a small gain everywhere. Couple things give me pause comparing the 2 pulls though. Weather was drastically different. Outside air temps yesterday were mid 80s. The last pull with S2T1s (484 pull) was done in March with outside air temps in the 40s. Also the 484 pull was a limited dyno session while yday car was on dyno for almost 4 hours so everything was very heat soaked. I wonder if we don't need more timing in the mid range. I don't have a knock setup and I'm happy with how it pulls (it is def pulling harder than previous setup) so I probably won't look into it. What I might do is wait for cooler weather and see what kind of difference that makes.
These cams are pretty awesome. The idle sounds so different. Love it. I'll get some idle and maybe some driving vids once we clean up the part throttle tune next week.
Yeah, I love the way it sounds. Sounds better in person though, vid doesn't do it justice.
It's idling a little warm, 202 instead of 197-199 on a warm day. I'm guessing the combination of higher idle rpm and conventional oil. Once I switch back to full synthetic I will see what shakes out but I may meed to make tweaks to my air flow for the radiator.
