merged posts lol.
|
that is awesome |
the fact there's no info?
|
No the fact that they'll build you a set to whatever specs you want
|
:-p
i woke up with lest posts than i went to bed with. not vewy nice |
I was looking into some cams for my setup.
I was leaning skunk2tuner1's but, haven't givin' up on BCIII+'s yet. Has anyone broke a set of BCIII+'s? I hear thats there problem. |
i wouldn't use either setup really. i would go pro series for S2's or BCIV's
|
What's your setup?
Your compression/piston choice will help determind what cams to run You can pm me if your genius plan is super secret yo. p.s. ok THAT was a little bit of sarcasm, but still serious about the pm if you're worried about secrecy |
My setup will be overcammed by both of those cam choices.
Im basically running an LS/Vtec with Rs Machine Type R pistons + .030" Head is going to be simple with ITR outters and Portflow inners with PF TI retainers and +.5mm valves. I was told I could get a max lift of .480" with the valvetrain via Tom at PF. Thats why I was leaning for a mild cam but more aggressive than Type R's |
wait, you want to go with something more aggressive than type r's and you want to run S2 TUNER's? don't waste your time. with that setup S2 Pro 1's would be perfect.
|
if you're wanting to stay within the 12.2mm lift then go with the following:
Buddy Club: Spec IV Extreme(stage 2) Intake Cam: 12.3mm lift 306* duration Exhaust Cam: 11.8mm lift 302* duration Skunk2 Pro Series: Stage 2 Intake Cam: 12.5mm lift 302* duration Exhaust Cam: 11.6mm lift 312* duration TODA Racing: 2nd Gen Spec-A Intake Cam: 12mm lift 295* duration Exhaust Cam: 12mm lift 285* duration Rocket Motorsports: M22 Intake Cam: 12.1mm lift 284* duration Exhaust Cam: 12.1mm lift 284* duration JUN AUTO: Type 3 Intake Cam: 12.0mm lift 304* duration Exhaust Cam: 11.5mm lift 304* duration these are reputable cams, make great power with 11.5 to 1 comp and above... i say go with these. |
They have too much lift and will induce coil bind in the higher R's
S2 tuners still make power over ITR's regardless. Im really leaning BCIII+. |
that is were in lies the problem...if S2 tuner cams will be too much lift for the valve springs you are buying, maybe you should rethink that purchase... ORRRRR take in consideration that the manufacturer is just telling you those things to save their asses, when in fact the valve train will handle what ever you throw at it.
not really. go bigger. its all i can say man. |
ps....
Skunk2 Tuner Series Stage 1 Intake Cam: 11.6mm lift 249* duration Exhaust Cam: 10.8mm lift 244* duration CTR cam specs: Intake Cam: 11.5mm lift 243* duration Exhaust Cam: 10.5mm lift 235* duration you see why i'm telling you to go Pro series ^ the tuner cams are shit. i know this. FROM EXPERIENCE. |
So your saying that the ITR/Portflow setup will handle Pro 1's. You have to take into consideration that Im going to run larger valves. Here is the message I received form S2
Thank you for contacting the Helpdesk at Skunk2 Racing. Tuner Series Stage 1 camshafts for the B series engine SHOULD run into no problems with valve to valve clearance when installed with oversized valves. What I recommend doing is having the camshafts degreed on the engine. Once the optimum cam gear settings for your particular engine have been determined, you can then check your piston to valve and valve to valve clearances so that you know for sure everything clears. Typically we do not recommend running oversized valves with our PRO line of camshafts, as clearances are very tight. This does not mean that it cannot be done, it just means that you must be careful to check your clearances. I am really only looking into a fun reliable motor that in the future I can boost. I know that Evans tuning found all kinds of power with Pro1's but, those arent my power goals. Even if Tom at portflow is trying to save his ass on max lift thats good. I cant afford to rebuild due to wanting huge cams. I appreciate the help I really do. |
anyone think ill hit the pistons?
85mm b20 with RS machines pistons on GSR crank/rods .006 off the deck .5mm over supertech valves Supertech springs and retainers Skunk2 pro 2 camz compression should be right at 12:1 3layer HG |
I'd say you'll be ok, but as we know we all shoud do, test it first. haha.
|
i would def plastigauge that setup.
|
i complete understand you for wanting to trust what they are saying. just remember in the back of your head sometimes they say things to save themselves from things in the future.
IMO, i would have a reputable person put the motor together, WITH the pro 1's, and make sure you have no clearance issues. if you DO, then there is nothing stopping you from going back to maybe the stage 2 tuner cams or something. just my .02 |
I fully appreciate your opinion. As far as building the motor, Im doing it myself. I am just going to wait till the machine shop is done with my head to see what cams I can actually run.
|
anyone got the specs on how close is too close? Im definitely going to be claying/plastigauging. Probly gonna use the fatty red kind
|
if the clay is torn or pinched (not just crushed) its too close
|
The problem with this setup is that you wont be able to run correct cam timing because your .5mm oversized valves will touch or be to close at the degreed spec for the pro 2's, and you'll have a shitty power band. So oversized valves will more then likely hurt your setup.
|
How would pro 1's clearence's differ from tuner 2's? There is very little difference in the vtec lobs, it's the primary and secondary lobes that are bigger giving you more mid range power
|
this is how you check v2v
|
now that i look at it, the clearances should be the same....but that doesn't mean there's a huge difference between the cams... 30+ degrees of duration between the two cams, but at the same lift.
ps...the primary and secondary lobe discussion is futile here, since dyno numbers aren't calculated off partial throttle. not to mention, none of the cam specs have anything to do with them. |
jesus when are both valves at enough lift to contact? Overlap should be relatively low lift...
|
I was jus stating the differences between the cams.
Do you only run partial throttle up to 6000rpm? NO! So, then the primary lobes are in full discussion. Most dyno comparasion's Ive seen, the pro 1's out performed the tuner 2's up to 5600 to 6000, which is the primary lobes, not vtec |
You will be safe with pro 1 or Tuner 2's. Although Skunk doesn't suggest running an oversize valve, it can be done. IMO The cams will need to be degreed and V2V and V2P should be measured anyway. In my case I have run larger lift and duration cams than pro1's, 2's even 3's with 1mm oversize valves but I know a few tricks to gaining that "extra space" needed to do so.
The real question is... do you have enough static compression to run these cams? Just wait till you try and run (succesfully, I might add) a 2mm oversize valve with an even larger .560/280+ cams and piss poor valve angles like one of my current engines uses. ;) |
