Web Cams....thoughts?

[Mistaspakles]

What are everyone's thoughts on web cams. I'm running them right now and am thinking of switching to HKS. Any thoughts?

 

[rdrkt]

Most people that switch from webs to HKS seem a pretty big gain power gain and an improvement in idle quality. ). The webs aren’t made anywhere near as well as the HKS. In addition to that the web street grind is 272i 256e does that make any sense at all for a turbo car?

I will know the results first hand as soon as my mechanic is done with this POS fwd 2g that he is working on now ( Larry)

WEB suck. HKS rock. IMHO.

I don't understand why the web street grind uses a larger intake cam either. Anyone care to explain this? it would seem that since the exhaust ports are smaller than the intake ports. A larger exhaust cam would make more sense? its cam time so im very undecided on which cams to get.

Im not sure why they use a smaller exhuast cam. Maybe it has to do with the old myth that turbos need backpressure.

At this point if the mountain of positive reviews and examples of HKS camed car doing well doesn’t convince you then I don’t know what will. Web quality control sucks you almost need cam gears to get them inline with how they should be. It has been proven time and time again that HKS makes more power. Look at what the people making big power use. I bought my 272s for 575 shipped. More power and better quality for a small premium in price. That’s all I needed.

The idle on the web street cams sounds pretty rough too. There is a sound clip on the RRE web site. I dont understand the intake cam being 272 either. Its like the exact opposite of the hks cams.

 

[jdmawd]

very true, as much as i dont want to fork out $600 for the hk$ cams. it seems like a logical choice.

Or you can get lucky like me and get them for 500 new in box-

my luck is not that good, ill just have to find a cheap place to buy the hk$ cams.

 

[L2RTSiAWD]

I think RRE is the cheapest.

maybe some people like their cars idling like s-h-i-t? I sure as hell love the guys car's that idle with webs here. A comment was made by a local dumba$$..."the white cars sounded like a$$ but the silver one was nice" it was in reference to the a white web cam'd 460 whp eclipse.

The webs idling better goes against everything I have ever heard of experienced first hand.

Could you go into further detail in better english this time?

Actually, I have a theory on the web cams timing thing. It is actually similar to what I was thinking of trying with HKS cams. If you use a huge intake you put a whole lot of air/fuel in the chamber. Now you compress it, burn it and get lots of nice power out of it. Now does anyone remember the theories of velocity on the intake side? As in why to use a small diameter runner, vary the lengths for bandwidth tuning, etc.? Well, now that I have this huge amount of air from my nice big intake cam sitting in the cylinder my small exhaust cam opens up. Since all that air still has to get out of the cylinder, and now in less time, it has to speed up by the laws of physics, right? So now I have fast flowing air coming out of the head, through the mani, and what do you know, a turbine? So now our fast moving exhaust hits the turbine at Mach 2000 (exaggerating of course). It SHOULD spin the turbine just a little faster right? So this would reduce spoolup, no? That was my theory. I was thinking of using a HKS 272-I/264-E. The only problem I can see is that the port size has more to do with velocity than cam timing. Generally, cam timing is the least important factor in air velocity (it seems to me). Again, I had thought about it and was thinking of trying it on the dyno to see the differences. But that is LONG way off for me. If anyone can expand on this, please do.

 

[rdrkt]

That theory is all find and good right up until you take look at what EVERYONE is running and making power with. Most people have seen pretty decent power improvements moving from a 264i to a 272i.

I do see what you are saying about exhaust velocity. I just don’t think it holds up in the real world. In fact even Mitsubishi has used a larger exhaust cam in stock 4g63 motors to make more power. I think HKS has a lot more R&D invested into our motor then web.

 

[RocketDSM]

No problem, I figured I was wrong anyway, but the theory sounded good on paper.

A large intake cam alone will not help give you a better intake charge. If The burnt mixture never gets fully exhausted than there will be less room for the next cycles intake charge. Exhaust velocity is very important in a turbo car, your right about that, however port shape, header design, and turbo placement are the best ways of manipulating velocity. A gain in velocity at a sacrifice in combustion effeciency would not be a good tradeoff.

crower has been making cams for a long time, and has a wide range to choose from, from "nice idle" all the way up to "stalling lawnmower".

but HKS is a wise choice, being that their cores are the only ones specificly made to which car they will go on

 

[larryd]

yeah HKS seems to be he for sure best bet when it comes to buying cams but I really love the lopey sound of my idle, the car was idling fine the other day, but still had that nice lobing sound to it I have crowers stage 2 incase u didnt already know

Cams are one of those subjects like religion.
Everyone has an opinion, including me

I have the web street grinds in my car and
am quite happy with them. I have also ran several other cam combinations with mixed results. I don't think you will see big gains
in swapping to the HK$ 272/272 unless you are running on the edge.
I am pulling 130 mph trap speeds and that is RPM limited, 8000RPM
in third gear in an A/T car.
