Looking to get some information on Crane Cams for a B16A1. Spefically the Stage 2 (radical street) and 3 (very radical street/race) cams. Has anyone used these that can offer their opinion? Or if you know of a site with some dyno charts.

By the way, I need info on these; NOT Skunk2, Jun, Toda, etc. I can either get these Cranes or nothing at all. Besides there are so many articles, threads, dynos, etc for those other ones. I am well aware of their abilities.

Thanks!

 

I'd be interested to see some opinions on these cams as well. Don't mean to hijack your thread FairlightRacing, but I figured I'd revive it and get some info for myself as well. I also wanted to see how these cams respond to adjustable gears and what people found to work well on them. Basically looking to save myself some dyno time. Crane recomends using cam gears, their ignition and a whole lot of other stuff:

I just finished my build using Crane's stage 3 cams, but was a little dissapointed with how they turned out. The mid range is pretty impressive, but the power drops off at about 6,500. I think I may have over-cam'd the engine, but I was aiming high.

Mind you, I still need to upgrade my ignition and would like to replace the stock 58mm TB with a 70mm unit and get my Skunk2 IM ported. Hopefully that'll help things out. If not, I'll be shopping for new cams in the spring. Also, I think the injectors may be a little on the large side. I got a set of MSD 520CC injectors for cheap, so I figured I could just trim them back with the tuning, but that also appears to have been a mistake. Live an learn I suppose.

FYI, my setup is a B20 with a PR3 head, 11.5:1CR and a JDM ITR header.

I made 216 with the stage 1`s. Pretty good IMO.

setup?

 

I believe voodoo had a 2 liter with around 10:1 compression.

I am running the crane 2 cams. I havent dynoed since the portwork and valvetrain/cams.

Its on a 12:1 compression block, ported head, crane 2's.

I was having severe idle issues with these cams for a while. I found it neccessary to reduce the overlap a couple degrees by advancing the exhaust timing 2 degrees. Now it idles like stock.

Power seems good, but cant comment because no tuning has been done, so most power hasnt been extracted yet.

I have had no mechanical problems with these camshafts as far as reliability or wear issues.

Nothing too special, just a good build and tuning.

 

Crap, I looks like I went way overboard on my cams. vtecvoodoo, your setup sounds pretty close to mine, and your numbers are what I was shooting for. Seeing as how Crane recomended their stage 3 cam for my setup, I'm going to see if they'll swap them out for another model. I'm not going to hold my breath on that one, but it's worth a shot.

 

baddest stage 2 cams on the market imo. been runnin them for a while now, but have never dyno'd them. with a 96 civic ex coupe, i run these in my oem built b16a and can beat k-series, and keep with a 13.5:1 d16z6 '88 crx si.

crane and ferrea for life.

 

I called Crane last night and found out that they recomend advancing the intake cam 4 degrees and retarding the exhaust 3 degrees. Hopefully that wakes them up. But it still leaves the question of why you'd design a cam that needed that much playing around. Why not just build it what that cam timing from the start?? I'll make the changes next month once the budget allows for re-tuning.

 

you sure they meant advancing the intake and retarding the exhaust?? Thats gonna bring your valves pretty close to together. Might hit, are u totally sure he didnt mean advance the exhaust and retard the intake?? I did this with my cranes and it them so much better. Plus this decreases the overlap, thus trapping more ccomprssion =more power.

 

You're probably right with the timing. It was a quick conversation, and I don't think I even got the numbers right, let alone if they were being advanced or retarded. I'm planning on calling back before I tune again, so I'll make sure I confirm that. Thanks for the head's up.

 

no prob. like i said with mine, i was having some idle probs with the stage twos, and the car was slower than with the stock cams. so all i did was advance the Exhaust cam a couple degrees. (decrease overlap) and all of a sudden it idles like stock and has great mid-high rpm power.

If you were thinking about it in your head u would think advance the intake and retard the exhaust in order to decrease the overlap and increase compression.

By advancing the intake, or retarding the exhuast, your actually allowing the valves to be open at the same time and more of your compression is actually leaked back out of the combustion chamber into the intake.

Go look at your motor and the cam gears and just imagine which way the cams would turn if u were to advance the intake and retard the exhaust. Your actually turning them towards each other!! (can be dangerous, plus your gonna bleed off too much compression for th car to run right.)

good luck
