Has anyone done a combination of cam gears and cam shafts?

I have seen alot in mags and on the internet, and the numbers are impressive, but I don't really trust the ppl that have done those tests. I am expecting a 3whp gain from a cam shaft. And something in the 6-8 whp from the cam shaft.

Can anyone comfirm these numbers?

Thanks


**Bruno- where are you man, have not heard from you a long time now. Hit me up sometimes, I have been busy lately and my internet is not working for sometimes now. I am using company time to type...

for what motor....might I suggest ctr cams, they wont' make as much peak as a skunk 2 stage 1 but they have more midrange so...and find cam gears with more than 3 bolts...jg gears are good from what I here...but if it's for a b18b than I think crower make ssome good ones for it....but ya what motor..?

Quick_CX

for for the money ITR and CTR(if u can get em cheap) are great upgrade for vtec dohc motors...ctr has liek a 3 degree higher lift on the intake cam....but those cams and type r valves springs and retainers, along with a nice set of adjustable cam gears...AEM STR whatever...will give u a nice improvement....skunk2 website has dyno number using there stage 2 cams on GSR...will give u a general idea of the power u will come close to...i think stage 2 cams in a gsr they said liek 20 hp...i think that might be a little high but still a good improement

EK7_DriftMania

does the bolts on the cam gears make a difference?

Why does some companies have more than others? Would the gears with the more bolts be easily broken?

Great info guys... going to their website now.

I have heard tones of good stories about these mods, but for some reason not alot of ppl are willing to do this mod? I mean I/H/E costs more that these mods and requires alittle bit more time etc... to install and costs more in the long run and Hp gain is not certain.

Why won't you guys be into this mod?

Thanks

Anybody checked out Skunk 2 website lately, they have some amazing garage sales.

some time i/h/e may lose power...some intakes..will rob power...but with cams...as long as u ain't going stage 3 and uupgrade ur valve train titanium valves and new springs retainers..ull be fine....and u WILL feel power gains...what motor is this??? u have a SIR? GSR?

I have a SOHC vtec...

I am also thinking of doing it to the Echo...

Why these cars? If you know me from along time ago, you know I got into an accident, I am trying to prove to the insurance that I'm not moding ****. So, all interal are unknown from just looking right?

That's why, it must not show anything. I will try the cam shafts on the civic, b/c it costs less than the DOHC Echo.

Thanks for the help.

EK7_DriftMania, sorry, was away for the weekend (as I usually am), and other than that, I have been a little busy. Your expectations for the HP gain are realistic. However, it's a matter of tuning. A cam on it's own won't do anything w/o tuning. It's fuel that makes the power, the cam just times the delivery of the mixture. So be ready to dish out some endz for dyno tuning. This won't be as easy as just resetting your ECU to just re-learn (though that may get you to the dyno)... you will need a fuel controller of some sort. A wideband O2 will be needed... the spark plugs can stay the same, but be sure to put a fresh set in there. As for doing mods w/o looking overly modded, I would think your best bet is to use OEM parts like B series t-body, ported/polished head and manifold, cam, gear, and tune that. You can try and mod a SiR air box to try to fit your SOHC, and put a K&N in there to make it seem stock but flow better. Use 1.6 EL exhaust manifold with an SIR cat back. When you are ready to get serious, then build it to rev to about 8500 rpm at high compression. I believe 180+ flywheel normally aspirated HP is totally doable in a SOHC, but with lots of money... LOTS.

I have only one thing to say for all you d-series guys...
Two litre d...
81mm bore, stock honda moving pieces, torque that a B20 would wish for, all in a sleeper d block...
I likey...

180 hp for a SOHC, will cause rough idles? 2.0L never heard of, but I have heard of the 1.9L, that was impressive, so I can imagine what a 2.0L would do. Is 240hp (S2000) possible for the 2.0L setup.

Bruno - I need hook ups and contacts... thanks bro...too bad can't meet you at the meet, i was still at work. That's alot of stuff to do, but I am looking foward to doing it. Does the SIR box do much? I had no idea about the tuning aspect to the gears and shafts combination, I thought it comes ready with instructions from the factory. Now I want to do it more than ever...

anyone can hook me up?

EK7_DriftMania

Hey, anyone heard of the Gforce tech meter? Is that thing accurate. I read that it could measure: 0-60, hp, G, etc...

Thinking of getting that - the new one has rev-meter build in.

EK7_DriftMania

Ok, I ordered Shunk 2 shaft for the SOHC, but not the gears.

Is it a much to go for gears? What about reprofiling? (good or bad)

Someone help me understand rough idling? I am afraid of reprofiling the shaft and have rough idles.

thanks guys

Ok, so you got a Skunk2 camshaft?? Get an adjustable gear too to best tune the cam... the lumpy idle has to do with overlap and engine vacuum. Really, Stage I cams should be very streetable. It's the big cams that make the idle really lumpy... you MAY be able to solve that problem by using the Golden Eagle vacuum manifold. Re-ground cams can be good and bad... they are cheaper, but not as strong.... good quality ones will hold up as long as you want your motor so don't buy shitty regrinds. But generally, anyone that makes cams actually makes them pretty decent. Not like Ractive makes a cam LOL ... that's too much precision work for them. :working: Either way, you WILL need a dyno facility to run your car on... cams are something to take pretty seriously.

Point taken

Thanks Bruno and everyone, I just can't wait to get the cam and gear.

How could a vaccum manifold solve the idle problem? By changing the manifold, would there be a gain also?

What about Gtech (i think that is what it's called) to tune? The commercial says all pros use them.

Oh ok... no the vacuum manifold is actually a box that STORES vacuum at times when there is plenty, and uses it later on when you need it to drive power accessories. It's not like you replace the manifold... that's just the term for it. It's an add on part rather than replacement. Do a search for Golden Eagle Manufacturing.... honda-tech has something on it.

G-tech pro, my friend has one... it's a accelerometer chip that measures Gs of force... it's pretty acurate... Made by tesla electronics... they have two versions... cheap one for $129 USD, and an awesome version for $249 USD. It's good and all, but nothing can replace an actual dyno.... I wouldn't use it for tuning my engine that's for sure. You need a wideband O2 at least, and a dyno to really tune. Can't do it on the fly...

EK7_DriftMania

Oh... I think I saw one of those vaccum manifolds before, drags and race use those right? I want max power, stage 3, how bad is the idle? and does the vacuum manifold solve that problem? Just asking before I buy.

thanks

stage 3??? Are you buying their valvesprings and retainers too?? Cuz... ummm they are BIG cams man... It won't be so bad that it won't idle... it's run like **** at idle and may not pass emissions at Stage 3, but it shouldn't stall I think you are making a mistake man... stage 3 cams make power at 6000+ rpm... how often do you hit that range with your car. You also need fuel reprogramming, and I'd also say some head work like a 3 angle valve job is in order and heavy porting... obviously springs and retainers... may want new valves. This is the kind of motor the Mugen ECU is tuned for...

Already, you are looking at more money that a cheap turbo setup would cost you...

The vacuum block is only to be used as a common vacuum source. Will do nothing to help big cams idle.
For cams like those (didn't know they made them for SOHC, don't really know the specs) you will need to raise the rev limit and install some new springs. You will see good benefit from some QUALITY porting.
You should really up the compression to run these as well.
Cam gear is a really good idea.
Do yourself a favour and pick up a Hondata, and pay for some dyno time...

Maybe I'm thinking of one of those vacuum reserve canisters as seen on muscle cars... eh donesixer... you must have seen those... they used them to store vacuum to run power brakes at times of low vacuum to stop the 4000 lbs beasts with drums in the front LOL Maybe Summit would be a good place to look for that.
