aight I'll try it and you should try gettin a camshaft all other upgrades are nothin without it.
Oh and what do you think of the trans interceptors. Leaving out the speed limiter removal and hp gain does it do the same change in shifting point as ur pcm?

That is incorrect as well....many people are running high 12s without a Cam.

Hehe, I looked at your car and for a second there I really had a believed in you. But saying that camshafts are not needed for your car!! I just realized you know nothin of cars dude. But I'm sure once you buy one u'll be like this is the shit and advertising for it all over the forum.

[GTPCatz]

No I was disagreeing with your statement saying all other upgrades are worthless with out a cam...that is pulling a lot out of your ass

sure a cam is the best bang for your car but it is not a must have to make your car go fast....if your shooting for low 12s then yes a cam will make it easier...

but your broad statement saying all other mods are worhtless without is pretty stupid....

i was wondering behvah78 what the function of a camshaft is?

[behvah78]

Camshaft is the rod which turns on its self and opens and closes the exhaust and intake valves. Some cars don't have it and instead have a valve timing electronic control(Vtec). Changing it would give you about 35-40hp at the wheel costs $500 and costs about $800 to install.

[AKWE-gt]

i thought that a vtec engine uses two cams, one cam during low rpms and then it switches to another cam at a certain rpm? what about rocker arm ratios? what happens when you go to a higher ratio like 1.6 to 1.9?

Well your wrong about VTec...ALL CARS HAVE A CAM!
EXCEPTION: Unless you have a rotory engine

and your wrong about the cam price and install!
a cam for our cars start out at 200 and cost 500 to install.....

[behvah78]

First of all No all cars don't have mechanical cams Some Hondas have a two cam shafts but there are things called MVT or multiple valve timing. They have infinite different valve timings. Just explain how the hell would those guyz run with a camshaft. second of all In my local stores the comp cams are 600 cdn+tax. If you want to buy it online even if you go for the cheap stuff and not x-p cams they are $300+ shipping+ about $150 of other things u need to install the camshaft like the rocker arm bolts dampner....Take out your calculator and add it up. Now installation!! You might be right about $500 but think of when u don't pass aircare and have to put the old cam back.And finally quit trying to make me look wrong!

[behvah78]

Just so u don't think that I pulled this out of my ass I add the link:

Now these guyz make this look like a new invention but it has been around for a while Lambourghini uses it BMW and Ford have made some prototypes and its widely used in aerospace. Just think about it if Grand prix had it that worthless PCM of urs could have made like 60hps.

[GTPCatz]

VTEC (which stands for Variable Valve Timing and Lift Electronic Control) is an electronic and mechanical system in some Honda engines that allows the engine to effectively have multiple camshafts. As the engine moves into different rpm ranges, the engine's computer can activate alternate lobes on the camshaft and change the cam's timing. In this way, the engine gets the best features of low-speed and high-speed camshafts in the same engine.

Intense Racing Sells Cams...one of the Best in the business...If you did your research you would find Comp doesnt make Cams for our cars!

And finally quit trying to make me look wrong!

I dont have to try hard....but if you would stop trying to prove me wrong I wouldnt have to make you look so bad!

and that link you posted is new...that is not in any current engine production designs!

[behvah78]

Hehe wrong again
The VTEC you are talking about is a marketing name for what Honda does!! Variable timing electronic control is a general name for anycar without a fixed valve timing. Comp doesn't make cams for our car!!! here is the link!!!!:
http://www.3800performance.com/vehic...97_03_miva.htm
And that link is new yes but the person who made it probably was as dumb as you are.
Well I'm giving you straight facts! Instead of wasting my time try to go back and get ur highschool degree maybe then u can spend rest of your life doin tune-ups. I hope u know what a spark plug is!!

[GTPCatz]

Looks I was wrong about Comp Cams.....it happens

but all hondas have a cam...
THE ONLY CARS THAT DO NOT HAVE A CAM ARE ROTORY ENGINE CARS...

If I am wrong please tell me what cars/engines have no cam
Those are the only "facts" I will look at!

as long as you dont do my tune-ups I will be happy doing my own!

[GTPCatz]

Here so you dont think these cars dont have a cam...all these are Honda VTec Engines...all have Cam (see DOHC or SOHC)

1996-Current Honda Civic EX coupe and sedan: 1.6L SOHC VTEC I4
1999-Current Honda Civic Si coupe: 1.6L DOHC VTEC I4
1996-Current Honda Civic HX: 1.6L SOHC VTEC-E I4
1998-Current Honda Accord LX/EX I4 coupe and sedan: 2.3L SOHC VTEC I4
1998-Current Honda Accord LX/EX V6 coupe and sedan: 3.0L SOHC VTEC V6
1997-Current Honda Prelude Base/Type-SH: 2.2L DOHC VTEC I4
1993-Current Acura Integra GS-R coupe and sedan: 1.8L DOHC VTEC I4
1999-Current Acura TL: 3.2L SOHC VTEC V6
2001-Current Acura CL: 3.2L SOHC VTEC V6
1991-Current Acura NSX: 3.2L DOHC VTEC V6

[behvah78]

I never said anything about hondas not having cams. This is what I said: "Some cars don't have it and instead have a valve timing electronic control"
Lambourghini done it. 2003 VW jetta had a limited production of it. Lotus will have a mass production of their prototype by 2008, Ford did a prototype in 1991. Also the 530E diesel engine and I think ford had it in some of their 2003 medium duty trucks.
