I was just wondering, what kind of gains can be had from using an aftermarket cam gear/gears in your vehicle? Are the retardation and advance in timing with the aftermarket cam gears something that you wouldn't be able to accomplish w/a stock one/set?

 

i've always thought of cam gears as an "accessory" mods, to go along with a built engine to actually make a difference.

 

from what ive heard cam gears only give significant horsepower on turbo applications.

 

well it gives a little bit of power just being lighter than the stock one, as a first. . . the retard/advance is somehting you can NOT do on a stock gear, a single cam application though the advance/retard only moves the torque curve up or down, nothing more, you cant go into the real technical stuff like overlap and all that shit like you can on a twin cam motor

 

eh i wouldn do it. id only do it if i minimally had an aftermarket camshaft but those dont exist for our cars.

 

i'm sure there are aftermarket camshafts available for the F series motor.

G22, In DOHC applications, what advancements can be seen w/them in retard/advance w/o aftermarket camshafts and with them, do you know?

 

with the twin cams you can get into whats called overlap, where you start avancing the intake cam while retarding the exhaust cam, or vice versa, stuff like that can yield varied results, very flexible depending on what sort of application youve got, eg. FI vs N/A. . . that all can be done on stock cams, the only difference between the stock cam and the aftermarket ones are lift, and sometimes duration. . . but all that can be worked around if youve got an adjustable gear this sort of tuning should ALWAYS be done on a dyno by a professional though


there are aftermarket cams for F applications, Bisimoto makes them and a place called F22parts.com or something like that

 

The retardation is strong in this thread

 

maybe it is, its been a while since Ive talked about cams and shit

 

ive only seen one cam for an f22b1. dont remember where, it was some site that like hand machines parts for the motor. i think it was $1200. ridiculous.

 

ROFL

 

Yeah Bisimoto is a company that makes cams for the F series. I dont think they cost anywhere near 1200 though, the prices that i've seen were similar to skunk2 and JUN at around 500-600.

As for the "retardation being strong" in this thread, this is something i know very little about so i was trying to get some info

 

Here's what my friend Marc told me:
"Adjustable camgears are used in adjusting cam timing (retards or advance). They can have an huge effect on your fuel curve, which in turn yields to more power. However tuning would be necessary. Also should mention it changes valve overlap which induces a change in where your motor makes its power."

guess if i buy em i should be making an appointment with the a tuner lol.

 

well... allow me to chime in youngin'

You have a intake. You have a full custom exhaust. Get the cam gear(s). Tune it.

And then we go for a ride. lol

 

lol. just trying to make sure it's money well spent. When r u gonna decide what you're doing w/ur car?

 

already did homie

 

this thread receives my stamp of containing no correct information!

 

then by all means, correct it

 

PLEASE do

 

you can get a reground cam from f22parts.com I think its like $300.00

 

you dont need a tune, with a sohc your basically moving the powerband, i retarded mine 2 degrees and found a much more useful powerband. it has nothing to do with your fuel curve. etc

 

thus I said torque curve, never mentioned fuel

 

whatever makes you feel better, but i wasnt even talking to you.

 

Makes sense. Just got me some Golden Eagle product so we'll see how it works out. Hopefully it's worth it lol.

 

while your on a shopping spree chris, wanna buy me something cool?

 

just a last ditch effort to save my limited inteligence

 

lol G22 you did fine, thanks for the helpful info bro , well at least i thought it was helpful

 

what's that i see in your avatar? H23A? ....explain

 

Ummm...thats nothing, just an avatar... for now

 

oh yeah....

interesting...

 

lol I pm'ed u Allan.

 

Your lift and duration CAN NOT be changed with adjustable gears.

There is a lot more than just Lift and duration in camshafts. In regaurds to aftermarket and stock.

Lift, Duration, Advertised Duration, Lobe Seperation, Ramp Rate, and some more. There are so many different combos, you can't even imagine.

The only thing adjustable with the cam gears is the TQ curve. Move it up in the RPM range or move it down. (Except DOHC while yes you can change overlap, but not lift and duration)

And yes some turbo applications will benifit more than a NA motor from retarding the exhaust cam (In a DOHC) a few degrees. The gains can be substantial.

Not bagging on ya, just a little FYI!

 

I'm no pro on the Acura motors, but is there not a Crankshaft to Camshaft sensor problem to deal with, when you say no tune needed when retarding cams?

Like I said no pro on the Acura, but I know in my Tahoe 350 motor, I put in a new cam and degreed it back 4 degrees. It did need a new tune, not just for that, cause I changed all kinds of shit, but the crank to cam sensor had to be delt with in the tune.

 

yeah I know, I did say stock vs aftermarket CAMs

 

"""""the only difference between the stock cam and the aftermarket ones are lift, and sometimes duration""""""""


Thats what you said, and it is not correct. Re read the post.

 

I was refering to your 1st sentence. . .

 

well every car is different, hondas do not need a tune tho. couldnt tell you more as to why.

 

You mean this sentence, my first one.

""""""""(ME) Your lift and duration CAN NOT be changed with adjustable gears.""""""""


Well you said, """"""""""""that all can be done on stock cams, the only difference between the stock cam and the aftermarket ones are lift, and sometimes duration. . . but all that can be worked around if youve got an adjustable gear this sort of tuning should ALWAYS be done on a dyno by a professional though""""""""""""

No You can't work around Lift and Duration with adj. gears.

Everything you said in your entire post is incorrect, except that you can adjust overlap with twin cams and adj. gears. Other than that everthing else is wrong.

Like I said, i'm not trying to be an ass, but you giving totally false info here that might give someone the wrong idea, and cost them some doe!

 

so you can't adjust lift and duration, but only overlap and powerband?

 

Correct! Lift and duration is decided when the camshaft is cut. No adjustment in the world will give you that. If you want to change lift or duration you have to have your cam recround, or get a new one.

Overlap on twin cam setup only. A single cam you can not change overlap. If you retard the cam on a single setup you are doing both intake and exhaust.

All you are doing when you adjust the cam, is changing when and where the valves open in relation to where the piston is in its stroke.
