Custom Bisimoto Cams
Why can't we all live closer to each other so we could all meet up and bullshit and turn wrenches and occasionally have a few brewskies!? I might not sound like the smartest egg in the acurazine world but I'm actually a damn good mechanic. I just am not good at putting the words to the keyboard lol.
I hope your build exceeds your expectations so you can continue to build her bud! Report back asap!
Seems like this thread took a turn for the fun!

it's a shame, really.
Sonnick or IntackACK will either of you guys be at Honda Day this year up in NJ? I will be going on Sunday and bringing my car. Would be cool to shoot the shit with you guys if you plan to go. Let me know and we can arrange something.
too tell you the truth i'm not sure. I just realized that was missing from the sheet when I posted it on here. I would have to make a bell curve like king did for ILC's (unless something else can be done to check it).
I also passed emissions with all my mods (3.5 bottom end with built head on stock 3.2 ECU). I had evap CEL on (not installed) and misfires in all cylinders. But my readouts were very low (still have stock Precats and cat).

Made my day yesterday lol....I just drove at higher rpms and tried not to sit at idle for any longer than I had too. I literally shut my car off rolling into my friends dealership haha. The mechanic pulled it up quick shut it off and when he hooked it up it all passed everything was A O K
The way I see things is people are pulling 30-50hp gains from these cams.
Nobody till now has ran into issues with any other cams. If one bank is reading more advanced than the other, THIS WOULD BE APPARENT SOMEWHERE. Wether by AFR's, plug readings, EGT's, something. You don't think the engine would run poorly from any of this? Or the ECM wouldn't detect any problems? Something just doesn't sound right about this newfound "discovery" that's being proclaimed no offense.
I say, roll with the cams until there's something seen worth bickering about. (As in something that damages/ruins an engine)

So 30-50? on cams? No offense but that's obscenely optimistic. By that logic I should be at 380 whp from this build, once you factor in 12:1 and head porting and PnP'ed runners.
No one said they are unreliable, no one said they won't run - I have absolutely 0 concerns right now about any of that.
The only proclamation I've made is that if you regrind a Type-S cam, you're going to have pronounced lobe separation and valve timing will be off, thus not making as much power as if you had perfect centerlines.
Until I see someone else who has a Webcams regrind on a Type-S cam and actually degrees their shit, and show me that the centerlines between front/rear cams match or are at least no farther than 2 degrees apart to contest my findings, my word is the one I'll be taking. You can believe what you want. We've had the same results on 2 regrinds of Type-S cam - one from my car and a brand new replacement from Honda.
I don't know how much clearer I can be - Webcams is in agreement with King's measurements and Web is the one doing all the regrinds for our cars, lol. It's up to you whether you want to believe me, but at the end of the day I'm the only person here who has gone to the hassle of getting any hard data. I'm not getting this info 2nd hand. I was there in the shop with King when we were on the phone with Web. Both parties were looking at the cams and seeing the same thing. Both parties ran the math and agreed.
If you want to discuss your doubts, then I would urge you to just call King. Mike's extension there is x301.
That would be awesome. If you can readily do it, please degree and report your findings in particular for the intake valve timing between front and rear!
What is your regrind profile? It would be interesting to see if there's significant difference there, given my assumption that we probably have different profiles

Secondly, I don't have a degree wheel and won't be able to do this. What I meant by we shall see is we shall see if its a continuous pattern as far as their regrinds go. The profile closely matches that of a Bisi stage 2 with a lift of around .480" with rocker ratio factored.
As for the 30-50 gains, that's a real world gain by a real world result. From two separate people. One being a completely forged j37 and made damn near an additional 50 with a few things being different from original setup. I expect about 375bhp from this current build.
First of all, I wasn't trying to be an arrogant ass in my last post. Sorry if it came across like that.

all i'm saying is that's really optimistic - maybe I'm setting the bar too low for myself but I have a very aggressive grind - significantly bigger cam than stock type-s now, and I have a hard time believing I could see 30 whp from just the cam. It just seems like a lot to gain from just the cam regrind on a J35.
when you say real world examples - I get the forged j37 but are we talking it was dyno'd as-is without the cam, and then dyno'd again after the regrind was installed? Or are we saying there was a 30-50 whp gain from the combination of those parts?
also, I would love to see threads/dyno charts of this for my own reference.
Yes, I'm speaking in regards of cams with supporting mods. But my point would be that these are mods that alone don't add much by themselves.
Kind of like if you install a manifold and it adds 5hp by itself. Then a set of headers that add 10hp on top of that. That's 15hp total. But these are breathing mods that allow higher flow potential but the current cam is maxed out in terms of what it can pull in because THIS is the limiting factor in our engines.
Now, the same engine with the same mods but with a cam that's significantly higher in both lift/duration and raised rev limiter could make even more gains from headers and manifold, gains from the cam itself as well as more RPMs to bring in even MORE air and yes 30-50hp definitely becomes a reality.
I don't have charts to support but search on Google for a j35z TSX by a Honda racing division that's doing 350hp by cams and valve train alone.

edit: i guess i could sift through your j37 thread, lol
I was hoping you'd have something from v 6 p - i've never really scoped the forums over there.
The best place to find build threads on our motors is here and v6p, yup. Go to the advanced search option and enter keyword "build" but ensure that "search titles" is chosen. J32a has a few good ones as well. There's even a few forums on dune buggies and sand rails that deal with j-series that have mostly NA builds but good info out there nonetheless.
light at the end of the tunnel:
I'm doing some custom cam gears (13 bucks a piece, w00t) to fix the position of the cams at +4 in the front and -8 in the rear - the cam sensors are going bonkers after 20-30 minutes of running the car and sending all misfire codes because at that point, the car actually is physically starting to misfire. It runs fine up till that point, but then it starts misfiring and the car needs to be shut off and codes reset. Cam gears should fix it.
Still working through some tuning issues between 6500-6800 RPM's. There are some oddities in the chart there which appears to be due to reverberation coming back into the intake manifold from the cams.
Once that is worked out, next step is upping the redline. At stock redline the powerband was still going up, so I'm excited to see where it will be at 7200-7300.
So far no knock issues - periodically have been boroscoping the cylinders (everything was inked red) and things are looking good.

random. When the car was first started up, it went bonkers after a couple minutes under no load. Shut it off, loaded a base tune, and it was fine. Pulled the base tune off, put my tune back on, and it was still fine. Ran just like it should, normal idle, fine under load until 15-20 minutes later, easing into things between 2k-4k rpm's, it goes nutty again. I was there on Tuesday with the tuner from like 3:30 until 9 pm brainstorming/spitballing/talking to Hondata.
That's what we said, lol. Cheapest cam gears ev4r!!

what i'm saying is that new stock cam gears from Acura are 13 bucks a piece. That's still super cheap for cam gears, but that price doesn't include a custom cut from King.
They are charging me 150 bucks per cam gear including the custom cuts that are being applied.

For $13.00 I could always make a shop clock out of them and still sleep very well at night.

My car has been running flawlessly with my stage 2 cams still, pulls like a raped ape....can't wait to tune in a few weeks. I actually recalibrated my wideband and my readings are way, but I'm still running very rich at wot and high RPMS. The factory ecu and injectors clearly provides enough fueling and adapts to the cams over time, obviously timing fuel mapping arent optimized but I believe you could safely run even stage two cams and make more power off the factory ecu. I received 7 compliments today and 6 were total strangers and I only drove my car to my friends 2 miles away lol. The 20 minutes I was around my car. Love being different. days like today remind me of why I'm keeping this car and modding the hell out of it. The new side skirts really put me back in boner mode.
Next is nos or turbo kit!

Just so you know, I did my first start up with the Web cams today. Growled like a hungry lion! I had my HDS hooked up during the initial start and through data stream I seen no cam/crank timing correlation and variance issues. Although it wasn't ran for anymore than a few seconds, that sort of stuff shows up immediately. I'm wondering why you're having such a hard time with these people. I mean, did they just suddenly change the method/procedure in which they regrind j-series camshafts and being unaware, created an accidental issue?
I should have everything zipped up on it real soon. I'll come back here and post updates on what data/information I obtain from my Web regrinds. Good luck!
