Would these work? :D

[Deuce Bigs]

they would.....i'm still gonna get the ones from supersix however. tom at supersix is a great guy adn they have great customer service. zooomer is questionable on clubgp(he seems to have some that love him and some that hate him). plus these are just modified stock ones whereas the supersix are brand new, double roller, and lighter. it's like anything else. you get what you pay for.

Did you e-mail them and ask?

I bet they would work but I think thats the wrong way to go about getting horsepower.

If you want more valve lift the best way to achieve it is by increaseing lobe lift on the cam itself.

Those rockers will not provide any less friction then stock. They will actually provide more resistance than a stock lifter due to the increased ratio.

What people usually do is go with a agressive ramp rate cam with a 1.5 roller rocker.

Also, by modifying stock rockers, the contact points on the valve side most likely would not be accurate. When the contact points are off on the valve side, either at max lift or 0 lift, there is a chance the rocker could fall off the valve completely.

I recomend going with a comp cams xtreme energy cam that already has faster ramp rates and stick with the stock unmodified rockers.

Thats what I figured, I was just going to let everyone pick at it a bit [img]smile.gif[/img] .

[Magnus]

E-mail them and ask, then let us know what they say. They will have more info about their product than we do I bet.

I would ask for pictures and how they achieve (with specifics) the higher ratio.

I agree with Keith here, the best place to add lift is in the cam. Of course it's much easier to slap on a set of rockers. I would he hesitant about increasing the lift that much on stock springs all in the rocker.

Tom is sending me some of those roller rockers to test fit on my spare motor, I'm going to check clearances under the valve cover with clay and also measure piston to valve clearance while I'm in there. When I get them I'll post pictures on my webpage of the process. If they work out I think that will be a nice combination of increased lift in the cam and rocker together, just need some new springs to handle it.

Thanks, Cardinal. I'm gonna check these guys out when I get ready to go inside the engine. Something about "no SES light" turns me on. I'm sorry, but the Cam thing is still in beta testing as far as I'm concerned. Hopefully, the people doing Cam development will come up with the perfect lift/duration that won't cause the SES problem, granted we may have reduced gains. I don't wanna get one and unplug the bulb. The light has a purpose.

[bluecmaro96]

magnus why would you go with comp cam and not ssm cam? what are the hrsp differences and lift duration differences?

[Magnus]

the Comp Cams cam are ground from full cores instead of reground cams like SuperSix offers. Being ground from a full core means more meet on the base circle. Also, the comp cams extreme energy series has a more agressive ramp rate which will snap the valves open at a faster rate. That is very hard to get with a reground cam.

Why would you unplug the bulb?

The current suggested Supersix cam makes the computer think something is wrong with the engine, and throws an SES light... Unplugging the bulb simply gets rid of it, since you know the car is running fine [img]smile.gif[/img]

Ah. So if I have a problem with the car, but unplug the bulb, then car doesn't know it has a problem so it runs fine. So putting a big cam in a car will cause it to run like yunk. But after unplugging the bulb, it runs fine. I can't believe those idiots that get tuning for their cars. They must be on crack paying all that money. All they have to do is unplug the bulb. Without the bulb, the car is totally lost and is not aware of any problems. So this bulb is like a center of the pcm. When this bulb goes off, the car can't run anymore. If you can't see the SES light, it's not there. And later if you have other problems, you'll never know cause you got that bulb out. Stroke of genius. I just want to know, who is the mastermind that stumbled onto this first?

[img]graemlins/rofl.gif[/img] Okay.

[Ironman24]

If you have a laptop and can read codes and monitor what the car is doing then there is no need for a SES light. Most of the codes thrown are emission related and don't effect how the car performs. Unpluging a bulb won't change how the car runs but I don't need the light on all the time telling me there is a slow response on a O2 sensor because I have no cat or I get a random multiple misfire code at idle because I have some major overlap in the cam. Light stays on all the time but the car runs great. If something is REALLY wrong you know your car enough to tell it yourself without the help of a light.
