Rep Power: 299 stage 2 na crower cam experience
well after 3 days of hard work i have my clutch installed arp wheel studs in and finnaly today crower stage 2 cam and spring kit in. I invite anyone with a stage 2 cam installed to post thier experiences (boosted or otherwise) here.
Idle is rough I would call it more than "slighlty lopey at idle" I believe there will be some smoothing out with AEM ems but with just vafc2 I would call it more than lopey. I have to say it does sound cool. Hot rod ish.
My cam gear is set to 2 degrees advance...i just left it as i had it before. I may experiement with it in the near future. I will post results here. Sorry but there is no before dyno. you will have to look at the last dyno i had, many mods back. and take my wod that I was putting around 130 ish whp to the ground. 60 bux is 60 bux. I will post the final dyno when it happens. Untuned it barks third gear on command < may have to do with the clutch I just put in. It pulls slightly harder than before. dare I say it.... I felt vtec kick in when at partial throttle. It is obvious to me that there is alot of tuning to be done. It is noticable louder than before. I will street tune my AF ratio as much as I can with my wiideband. At partial throttle the af ratio is all over the place. < there is not much you can do about this with just vafc2. The stock ecu adjusts quite a bit. I am starting to look at EMS as my next mod. When I started my obsession with making na d17 hp I never thought it would go this far. My k swap looks so far away now. I keep thinking "maybe I will be satisfied with just this" ...NOT. Stay tuned It has just been a few hours since the install and I have only driven it a couple times. More to come.

Rep Power: 0 thats weird.... i know the ems or e-manage is so much better but my neighbor has a b16 swap with 75 shot, skunk2 stg2 cams, i/h/e etc tuned with vafc and my friend with a DA teg has a b20 bottom and a ls head with crower stage 3 cams and he tunes it with the safc and there air/fuel is pretty good but u can hear the cams especially at idle. I am pretty sure ur air/fuel will be much better when tuned at a dyno. I also see quite a few people use the vafc or safc with dsm injectors tuned on 8 psi turbo setups so u should be fine, but if u got the coin for the ems deff do it. That would be sic to see a d17 with full pistons, rods, ems, cam, and with a lil bit of nitrous get in the high 200 hp range. Good luck.

I'm sure with the ems, you'd be able to take a good advantage of the cam ... with the stage 2, I'm assuming you also have the valve springs/retainers?
hello 8k redline?

Rep Power: 299 yup sprimgs and retainers are in there. I would not raise the redline untill I have ARP rod bolts... at the least, installed. A tuned dyno will tell where the power is at. Time to call some shops and get a price on tuning. A ride ...sure when its running as good as it can. I have yet to try spray thru it. I want to know where my timing is at.

Rep Power: 299 I don't think that the stage 2 cam is for everybody. There is definatly a sacrafice in drivability. The idle is rough and it actually cuts off once in a while. You can't just stomp on the gas and go. you have to feather it up to 2k and then its cool. I personally think that vafc2 and a cam gear is not going to cut it. I'll haVe to get it tuned by a pro to find out for sure. I think that e manage with the ignition harness would be minimal to get this cam to idle better and probably perform better. < this is only a guess since no one has tried it yet. I'll monkey around with it for a week or two then take it somewhere.

Rep Power: 257 Like I said in another thread I think the only right way to use this cam is with EMS. I am going to have one installed and tuned hopefully by Aug18th. I have the Stage 2 with Vafc also and it just ain't right. The ECU makes idle jump around and once it settles at 800 (stock idle ) it is hella rough and does feel like cutting off... DJmota I had to put my VAFC @ -29 at 1000 to get it to idle withough cutting off...was flooding it at first. I agree with DJmota tho it ain't for everyone. If you want the "slight lope at idle" them get the EMS at $1500ish ...that is the ONLY way it will run right.

i think once you get it tuned up it wont stall on you or anything. just my thought.

Rep Power: 299 oK small update. Fuel at WOT is close to where I want it, not exactly but close. The vafc2 will not give me any more fuel. I believe the stock fuel map is maxed out. Idle is still rough although it does not die on me anymore. I had fuel setting on the plus side at idle. I think this retarded the timing and made it hard for the ecu to keep it idling. I set it to zero and it helped a tiny bit. It pulls nicely. Playing with the cam gear is next. I am hoping it helps the idle more and helps the 1000-2500 rpm range more hospitable. I think I see AEM EMS in my future. Once my clutch is broken in I will try the spray.

I love the lumpyness to.
I was at the track and a mustang guy with super lumpy cams, looked over at my car sputtering away( i had the cam gears adjusted so it wouldnt idle for my than 20 seconds by itself) and said" its funny cause your car sounds worse than mine, it puts a huge smile on ur face when u sound like a harly. Have fun tuning, u can probably squeeze 4-5 more hp outa the cams with SUPEr agressive tuning.

Rep Power: 299 I Played with the cam gear this weekend. tried advancing it 2 more degrees +4 idle felt the same if not a little worse performance and AFR unchanged also gave me a CEL after a day or 2. gave it a shot at 2 degrees retard and to my surprise the AFR went richer than it was in the past. I believe that I was wrong previously about being axed out. I now think that with the adv settings I had the intake valve closing too soon and not letting in the full air/fuel charge get in the cylinder. It "feels" better when I am on it but that could be just my head. It does bark third better now Idle is the same and it gave me another cel this morning. I am going to try it at zero to see what happens there next. I know I need a dyno to really tell me whats going on but I am just experiementing and learnig at the same time. I am going to try and make it this tuesday to the local 714 meet. and maybe even to the one in cerritos this weekend. It been a while since I showed up to an event. IMO I still need EMS.

Rep Power: 299 The new one is not out yet. Supposedly it will be the next ems realeased but who knows when that will happen. When it does I plan on picking it up. Small update. I dorve my car to las vegas from LA And got a cel that does not go away with resseting the ecu. Now my idle stays at 1500rpm. Also something wierd when I let off the gas to decelerate the ecu does not cut off fuel like it did before. I think I am in a sort of limp mode ignition map. It still revs all the way up but just not quite as fats as before. I think Its time to pick up an obd2 scanner.

Rep Power: 299 scanned the cel it has nothing to do with the cam. low tps voltage. turned out to be a broken wire where I tapped for my n20 It did not run too bad with no tps.

Rep Power: 257 supposed to be the 30-1030 which is supposed to fix the AC problem...that is what I was told at least...guess we will find out. think it was the 30-1070 that you had to rewire the ac.

Rep Power: 299 I had to take an unexpected trip to new mexico this weekend in the vic. 800 miles one way. No problems whatsoever. for those wondering about gas milage. I got 35.7 miles to the gallon hwy doin about 85 all the way. I was pretty impressed that it still get good milage.
