I plan on getting my greddy turbo kit this summer, but until then i have some cash to do something to my ride to try and get some hp or get faster times at the track... i was looking into some AEM PULLEYS and CAM GEARS... Does anyone have them?

If so, Do they do anything for speed-wise? or hp increase? should i get them? are they worth it? which pulleys and cam gears are best? damn, so many questions, any help is appreciated...

anyone?

 

Yes, both pulleys and cam gears will free up some HP, allowing for faster track times. Pulleys will allow accessories to be driven with less of a drain on the engine. Obviously, this will free up power. How much power....I can't tell you that. I haven't seen any dyno plots of cars with just these mods.

With CAM gears you can dial in torque depending on where you want it. CAM gears are a little lighter too.

All in all, with bolt ons...I don't expect much. I think as you do more bolt-ons...you will see better gains. But just simply putting on pulleys and cam gears....I wouldn't expect much. It will definitely help...but I doubt anything noticeable.

I am going to do these mods when I get my H22 because I am going to use my car for the track and I think relieveing the motor of power drains like pulleys, restrictive intake, exhaust, etc...will yield longevity of the engine...not power gains. I am sure they will help but I just want my car to breath a flow as best as possible.

I hope this helped.

 

ANDYD, much help, i figured having lighter pulleys and cam gears would help the engine to operate at a lesser stress level...

****, it would be great if everyone posted replies like you...

btw, i have aem cai/dc sport 421 header/greddy evo exhaust... u think putting in some AEM PULLEYS and CAM GEARS will help out at the track??? i'm tired of hittin the track with the same set up of just i/h/e...

 

Pulleys will not make much of a difference or even any difference at all man. If it was a big thing...why don't I see all these people with forced induction honda or acuras or n/a car with them? I've seen alot without and heard its not worth it. Cam gears on the other hand yes I would recommend! Cam gears won't provide a whole lot of power either....maybe 3-4hp tuned. thats it. Don't expect major gains son!

Dont' waste your money on pulleys. They are waste of time and money and labor. Spend your money elsewhere......

 

I'm too cheap to get some pullies. Instead, I just remove the PS belt.

 

Pully kits do next to nothing. and they shorten the l;ife of
your crank bearings. Not worth it.

 

from the guys here that do some dyno work

they said that alot of times they see the best cam gear settigns almost at 0
i think honda knows more then enough to make sure its timed and setright
unless you want to do some weird adjusting.. IMO

 

ok more posts w/o proof. Ghey.

here's the pulley results on a 1.6 VTEC (yes yes smaller engine), but the Power streering was already removed so the only thing the pulley was powering was the alternator. they used the unortho, and the increase is about a steady 4.2 from 6800 to 8000 (red line) with about a horsepower or more for the rest of the band. Torque sees the better of it, with nearly 2 to 3 ft/lbs for the whole power band. Again, this is just running the alternator. The cam gears showed typically at most a peak of another 2 to 3 hp.

And for anyone saying it's a waste of money... all of you looking at getting something like the skunk2 manifold or some other intake manifold.. that's more of a waste of money unless your car can revv to over 8000 rpms. in all the comparisons made, (same engine, yes not a H series but will have the same affects) the factory intake outpowers the Venom, Skunk2, STR, and the Killer Bee (only in torque where the stock had 4 more peak ft/lbs, killer bee had 7 more peak HP) All the others i mentioned (Venom, skunk2, str) only started to show power gains right before the red line. if you could rev out to 10,500 then they would be worth it. The results will be reflected even under boost conditions because the large penum, short runner design will still carry the same affects

 

I can kinda see how a 1.6L can benefit from pullies since their torque output is well...lacking. At that displacement, every little bit helps.

I'm not saying that the 2.2 is a big block in itself...but it seems to be the general consensus that pullies either 1) Don't do squat, or 2) We don't have enough mods, or not at that stage yet to benefit from pullies.

And there are a few horror stories of aftermarket crank pulleys too...but let's not get into that.

 

The main reason i ask, is because my friend has a jrsc, and the rpm just flys when he revs or accelerates, and i heard that pulleys will help rpm climb more quickly, thus making the car faster. I konw pulleys aren't jack **** compared to the power of a jrsc. also, i heard that a flywheel is the best way to increase that rpm speed, but then you need a clutch, or so i heard again... hahaa...

thanks to those who have given me advice based on proof. but any 97-01 prelude owners out there with some helpful info?

 

LOL! No wonder!

I'm sure he means a smaller pulley so the SUPERCHARGER can spin quicker and get more boost!

 

i heard that a flywheel is the best way to increase that rpm speed, but then you need a clutch, or so i heard again... hahaa...


You don't NEED a racing clutch if you have a racing (lightened) flywheel, but the racing clutch will help the gears grab harder. My friend has a fully modded VR6 with a 10lb flywheel and a stock clutch. But that's off the point, yes a lighter flywheel will help the engine rev quicker and decelarate quicker.

 

Thats the whole point. To grab the gears quicker with no inbetween lag between gears. Once you go FI my friend.....I say the clutch will be more profitable for your money than the flywheel. IMO.

 

okay, pulleys do make some hp, especially torque down low, but, when idling, your lights will dim and pulleys will not allow you to use and heavy audio systems. when you are talkinga bout pulleys shortening the life of the crank, that is UR racing pulleys, AEM doesn come with a crank pulley. cam gears will help, but not much. i would recommned getting an AEM EMS with your turbo set-up. your friend was talking about the supercharger pulley, and when his rpms sour, its either the supercharger or he has an afermarket lightwiehgt flywheel.

 

i have a set of aem pulleys, i like them. I can't say i noticed a big difference because i put them on at the same time i installed my ACT XTSS and CM flywheel. Every hp counts. And to those that say that it's a waste of money on labor, do your own labor and save even more!

 

The knock on the UR crank pulley had to do with detaching the harmonic dampener. I've heard the horror stories and I've also heard people who said they ran it long-term with no probs. Go figure.

Same deals with the AEM pullies. There are some that ran the acc. pullies with high-end sound systems (up to a certain wattage) and didn't experience any probs either, sooo.

Common (documented) knowledge that cam gears do show small gains.

Now, my .02. If you're going to go turbo shortly, why waste cash now on minimal gains when you can spend the money on something that's gonna help the turbo make more power? Take that $200 or whatever bore your tb or put another $150 to it and get the NX Ntercooler after you get the turbo, or use the money for dyno time or a wideband o2 sensor or plugs or whatever. It's your cash, and you may very well have large reserves of extra loot, but I know I don't so I wanna make every dollar count. If you were gonna stay n/a I'd say go for it, but you're not. IMO don't waste money for 5-10 hp now when the same amount could get you 50+ hp later.

I know your thinking because I'm in the same boat; I'm saving up for the same kit and I'm tired of being ******* slow in the meantime, BUT I'm just gonna be patient and wait 'til I'm blown. Why throw money away scraping a mere tenth (if that) off of your times when you can knock off a whole second later?
