Cam Decisions...

[Marknbacon]

Alright, I'm going to be ordering my cam hopefully in the next month and I have a decision to make. I'm pretty sure I've got it narrowed down to three. I would LOVE to see videos of how your car sounds with these exact cams if you have them, and maybe some input on general drive-ability and satisfaction.

Option 1: Comp Cams XFI extreme energy-R 224/230 (SKU 51-444-11, aka XER273HR)
Specs: (@.050 duration) 224 intake, 230 exhaust, 114 LSA, lift (in/ex) .581/.588, intake centerline 112.

Option 2: GPI SS2.
Specs: 228/240, LSA 112, lift .646/.637, ICL +4.

Option 3: TSP N/A stage 2
Specs: 229/224, LSA 112, lift .629/.615, 112 LSA, ICL 109.

Right now the car is pretty much stock but when I put the cam in I am planning on putting kook's long tubes w/ HF cats as well.

Let me know what you think.

Thanks guys!

Search youtube. You will get better results.

You tube has a lot of vids, and after years of looking and listening to them went with a TSP Stage 3,,,231/246 @112 LSA , love it, been in the car for 14k miles...

I have the TSP stage 2 NA cam, but I can’t post the video. PM me and I can get you a video. My car sounds knarley.

I have never heard of sound being the deciding factor in a cam. I thought it was supposed to be performance.

Gotta sound fast fast...

It’s definitely not. But there is a certain sound I’m actually trying to avoid.

And I’m also interested to hear how driving with them has been.

I’m actually leaning towards the less aggressive of the three, the COMP.

Idk if you know and if you do I apologies . But I would hope your gonna do a trunion upgrade . Hate to see all your good work go bad, there’s also more than just putting a cam in too . Push rods springs retainers etc.

I know NA is different than boosted. I have a stage 2 on my Z and it is more than enough. A little surging and bucking...I can't imagine having a stage 3 in my Z in the city.

Oh yes. Most certainly. Planning on BTR duals with hardened pushrods and probably just steel retainers (might go with comp’s tool steel. Haven’t made up my mind yet) and planning on CHE trunnion upgrade if I can find someone that has them in stock.

I already have some of the basics here or on the way like a new cam retainer plate and ARP balancer bolt.

I have a big cam, and it drove like butter before my clutch and FI install.

Driveability will depend much more on the tuner rather than the cam itself (at least for the 3 you are looking at)

Whichever cam you go with, the higher the LSA, the smoother the idle will be. Just something to keep in mind

Mark, I have ALMOST the same cam as that GPI SS2. Mine (GPI SS1) has the exact same lift, but slightly less duration @ 224/237 and 7º overlap. Are you L99 converting to LS3 or are you a manual car? Because If L99 I would suggest a convertor with the #2 or 3 cams you listed. Although mine is 'only' a stage 1 cam, it's no slouch (especially compared to other companies Stage 1 cams) and causes quite a bit of push at red lights and stops. The car shakes and lopes like crazy in traffic. Personally I love it this way, but I will seriously benefit from a convertor install. I had very little bit of loss on the low rpm end, but nothing too bad. Top end pulls like a beast...but I'm not done yet. Mine was an L99 car but I swapped in a rebuilt LS3 last year and am still running with the 6L80e auto trans on a stock convertor (for now).

So my guess with the SS2 is you can expect a little bit more lope than this (video), otherwise it should be fairly close, at least for comparison's sake. I asked Ryan to tune the nastiest lope he could while keeping it streetable/tolerable...and boy did he!

Here is mine on the final GPI/Ryan remote tune on a cold start and then closed loop idle. I believe it was the 8th revision of the tune that got it to idle like this. I highly recommend listening to a lot of people here's advice on this topic. Do your research and consider your ultimate goals and how these different cams factor into your overall plans. The reason I say this is because people told me my cam would push, that I would want a convertor/gears, etc. with this cam and to just go bigger. I didn't listen. While I love my cam, I already kind of regret just not going with Stage 3 since I am already dealing with these 'issues' and will convertor/gear upgrade later anyway. But I really don't consider any of this as issues or problems. They are just small reminders of why I need to keep modding the car to perfection.

Sorry to those that have seen me post this video multiple times in other threads lol. I need to upload some fresh stuff. It goes into closed loop lopey lovin at around the 1:30 mark.
