Cam question I put a TR224 in my car and it is not making the power that it should be at all. One of my friends thinks that it might be a couple of degrees off. But, when I put the cam in the motor it looked like it can only go in with the dots aligned or way off. I am obviously very ignorant about cam installs, and I just made sure the two dots lined up (turned the motor around a couple of times to be sure) whick they did and I put the motor back together again. Should I take it somewhere to have the cam degreed in? See of that would give me my lost power. Or should I keep checking elsewhere for where my problem lies?
Re: Cam question You need to describe low power better, when off line high rpm? Did you use a new adjustable timing chain? If yes is it installed strait up? Does it miss or is it less power than stock?

Re: Cam question By low power I mean 337rwhp, with the 224, mid-length headers, cat back, pcm tuning, pulley, and lid. I used the stock timing chain. I had the car autotapped and it was running .92x and .94x mv's (I know that is rich, but I don't know if that is rich enough to kill that much power). On the dyno my a/f went from a 12.4 at 2500 then dropped to 12.0 from 4500 to redline. It does not miss, and the power is right about where it should be without the cam.

Re: Cam question <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" /> you know when I made this post all that I was looking for is a VERY SIMPLE YES OR NO. What difference does it make what "low power means" or what all is done to my car, or what tranny I got if your not going to answer my question? Everytime I ask a simple question on this board this is about the response I get. Do you do this you can look like you may know what the hell you are talking about? It is really simple, should I get my cam degreed in, or is that just not needed? YES OR NO? I think not, the dots lined up when I installed it. But, I don't know. This is why I ask.
Thanks for the lack of help, no really its cool <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" /> <img border="0" alt="[bullshit]" title="" src="graemlins/gr_bs.gif" />

Re: Cam question During the removal of the cam were the dots lined up.If not that could be you're problem.It does not matter if you lined them up after installing the cam because now crank will be at a different postion.

Re: Cam question Well, the dots lined up and I changed the springs to 918's. I got the TR stock length pushrods. I forgot to say that I did hollow out the Cats. When I swapped the cam I did go with the NGK tr55 plugs, but I left the stock wires on (at the time there was only 15,000 on the car). Anything else you need to know about my car?
I do wonder about the cam itself, but when I brought that up with Jeff@tr he said it was the right cam, and his cams make the power, so it must be my car. It lopes, but I am just not getting any power increase at all. I'll tell ya, I have been messing with this for months now, so me getting pissed is just simple frustration.

Re: Cam question I can understand your frustration. Is your air filter clean? May sound stupid, but have you checked all easy possibilities? Another thing, what mods do you have, and what type of dyno did you make your pulls on? After my TR224 install, I had 387rwhp, 376rwtq. This was on a Dynojet, with mods listed below.

Re: Cam question My mods are listed above, but I can repeat them. I got Bassani mid length headers w/ hollowed cats, lid, Borla, fra, TR224 .561 112, Compcam 918 springs, Tr stock length pushrods, K&N, and pulley. I just checked my air filter and it is clean. I ran on a dynojet. Also above I say how rich my car is running, but according to my friends it is not that rich to steal 35-40 hp.
Re: Cam question Yeah, that's not rich enough to kill a lot of HP's. My first pull after the TR224 had an 11.9 A/F ratio. After tuning, I picked up around 10 rwhp, with an A/f of 13.1 across the board. I'm at a loss. Maybe your clutch is slipping? Did you notice any SOTP gain, or was it not noticable at all? Maybe some one else can chime in also.
Re: Cam question Um, actually no. You can turn the crank over a million times without the timing chain on, and it will be in the same position when you install dot to dot. YES, you need to degree the crank. This will verify that you have the correct cam. No need to get pissy dude. Everyone is just trying to help. If indeed you have the correct cam, then your problem lies elsewhere, such as springs, fuel, or spark. If your cam is a couple of degrees off, it will not affect power, but rather shift your power band up or down a few hundred rpms. What springs did you install? Are you using stock length pushrods? Give more detail!

Re: Cam question No sotp gains for me, as a matter of fact I lost in a race from a roll against a Z that is modded like mine, except the cam, and his is a TC auto. I don't notice the clutch slipping at all, but I am going to order another one once I get caught up on the funds.
