Re: cam setup question

smoke panther, every time you reply, it is in a condescending tone and its really getting on my nerves, i dont car if your a moderater or not, if your going to be an a$$ toward every thing i have to say id appriciate if if you would just hold your tongue instead (or rather you fingers, since it is a keyboard) and besides, a reply from UDLOSE gave me advice saying that 1.9 rockers would provide similar gains. the criticizm your providing isnt constructive.

this is a technical forum, so if you have a personal problem with me, PM me and I promise you we'll sort it out.

and besides, a reply from UDLOSE gave me advice saying that 1.9 rockers would provide similar gains. the criticizm your providing isnt constructive.

UDLOSE doesn't know what he's talking about. Rocker arms only change the lift; they do nothing to the LSA or duration...so what you'd basically be doing is going from the stock cam, 182/192 .258/.258 115 LSA, to the equivalent of a 182/192 .306/.306 115 LSA cam. UDLOSE said he couldn't rationalize going to a mild cam like the GT1, but then he turned around and basically told you to spend the same amount of money on rockers, which would give you the equivalent of a microscopic cam, and all the benefits of one as well. Rocker arms netting similar gains as a cam swap? Hardly. Show me ONE 3800 V6 f-body that is in the 13s with just rocker arms being the only internal mod.

You need to do some more reading.

BTW, why aren't you running this 218/218 cam?

Re: cam setup question

Advertised duration numbers are taken at .006 to .010 inches of valve lift depending on the cam company, not as soon as the valve moves. So higher ratio rocker arms WILL change the duration numbers because the valve gets to this lift quicker. The .050 duration number changes more than the advertised. It might not be much, but rockers do add duration.

I have HPTuners on my laptop, so I'm not as limited as the OP. Also, the cam I have currently holds the cam-only record.

It might not be much, but rockers do add duration.

...thus, one is still left with the problem of having the equivalent of a miniscule cam for the same price as a larger, substantially more effective one.

Re: cam setup question

Ditch the GT1, go with the GT2 or Abbott's N/A. Both are nice stock tune cams, that many people run.

Don't know how I missed this, but the ARHNA cam is NOT a "nice stock tune cam" if one intends to race and get every ounce of performance out of it. Getting it to the point of DDing, sure it can be considered plug and play, but there is work to be done when trying to get your money's worth for the tuning and the cam. With stock tune, the harmonic of that cam generates quite a bit of KR; there was about a 7* spike at 5300ish RPM in any gear. By changing the fuel tables a small bit, it dropped to exactly 2* at the same RPM point...yea, that small change may not represent a complete victory or hours and hours of tuning, but that small step is completely out of reach of anyone who decides to take shortcuts with their cam and not tune their car.

Re: cam setup question

My bad, I was always told it was. As for the rockers, like I keep saying, they're a waste of money IMO. If you're going for a sleeper look, then they may be what you want, since they won't cause as much lope as a cam. They will show some nice gains, but for the price, a cam will show better. Now, if you could afford both and have enough valve clearance for both, then by all means get them.

blubbachub, Smoke's just trying to help out man. I totally agree with him, and I would have gotten that same cam he posted, except I got my GT2 for dirt cheap in almost new condition. He may come off as offensive, but it's an online forum and even the most considerate things can come as offensive to others, it just depends on when/how/who/etc reads it. He's not trying to bash you, just trying to help like the rest of us.

Re: cam setup question

Man... I was gonna do a cam swap after the header install... I read all of this and learned one thing and that's I don't know sh!t about engines and cams! I think I might hold off on it now lol

Re: cam setup question

A cam isn't hard, set aside a weekend if your doing it your first time. Make sure you can jack the car up since you need to stick a screwdriver in the flywheel if its auto. Helps to have an air compressor to hold the valves up, but I've been lucky when I did LS1 cams. Springs are mandatory with a cam so you need a valve spring compressor tool. Can be a pita, don't drop the locks :)

Read up! :P

Re: cam setup question

218/218 .528/528 112 110
^get that cam. It held the cam-only record with no tune for a long time, with stock rockers too

hey smoke whats the 110 and 112 numbers? is the LS 110 or 112?

[IDoVoodoo]

Re: cam setup question

112- lobe separation angle
110- intake centerline

Re: cam setup question

112- lobe separation angle
110- intake centerline

so whats the intake centerline for the GT2 and Abotts N/A cam...how come the sites doesnt give those specs? and what does intake centre line mean?


(tried reading the cam terminology thing in one of the posts, think it was the sticky but the link didnt work)
