Comp Cams 218/224 is the largets cam that I can put in my Z with a stock torque converter. Compared to the stock cam for the LT-1 how rough of a idle does it have???

Thanks fer any help

 

oh yeah if you can is there any way that you could record the idle off of the car and post it in here or a web site you might have so that i could hear it ???

Thanks again

 

Just put it in.The idle isnt too rough.Enough so that you can tell it isnt stock.So far I love it.Shouldnt hurt mileage either.

 

my hotcam is a 218/228 and with a pcmforless tune, it idles just as smoothly as a stock LT1.... well, almost. Its not noticeable unless you're looking for it.

sounds pretty good at idle too - just don't expect a huge chunky idle like a cc306.

 

Yeah, I've seen/heard of people using bigger cams w/the stock TC, but you'll like this cam. It doesn't seem like anyone was going with the CC502 until recently; now more and more people are either talking about it or running it. I'm running the CC502 on a stock tune right now. Let me say this, I wouldn't want it to idle any rougher than it does now; or any smoother-it's JUST RIGHT! I'm almost reluctant to have it tuned because the idle sounds so good, I don't want to lose it! The car goes like a cheetah on PCP, and I still get over 27mpg on the highway. With that being said, again, you'll really like this cam .

 

Hey thanks fer all the replies on my question

And i have one more to ask Has any one with that cam tried to pass emissions. just wondering around where i live they only do it for 97 and newer i think. just wondering incase they decide to change it

 

People with bigger cams have passed. If they can get a Hotcam and the CC305 to pass, this cam will pass with flying colors. I don't necessarily know if it would pass without tuning, but with tuning, definitely.

 

I think it will. I'll know next year when I take my car through the im240 test here in jersey. I'll definitely post the results, I have yet to see anybody post any figures from an im240 test.

 

I keep thinking of more questions to ask yall

I called Comp Cams today and asked them what exactley it means by aftermarket chip for my car to be able to run this cam. they told me that i needed to call someone like hypertech and see if the power programmer would be able to modify the computer to run the cam. So i called hypertech held on the like for a good 10 - 15 mins finally get someone and they told me that i would need to find someone on the internet to do a custom tuning on my computer.. What do i need to do about this... should i just drop down to the 212/218 cam that does not require a aftermarket chip. or is there something else i can do that will not empty my bank account? ?

thanks again for any help.. im sure I will find something to ask in a few days

 

Any one ???

 

I have a generic off the shelf hypertech program in my car and I got the numbers in my sig. When I took my car for a dyno tune with bryan from pcmforless, he couldn't best the hypertech so you should be fine. One thing to consider though is that every car is different, so you may have to get a custom program. The only way to truly know is if you dynotune it. Hope this helps.

 

I'd go with a custom program if I were you. Either www.madz28.com or www.pcmforless.com should both work great.

 

I have been running the xe502 on stock tune for a while. Although I think the car would benefit from a dyno tune mainly to work out a few drivability issues such as cam surge and rich cold starts but all in all the stock tune should work OK. That being said I did have to raise my fuel pressure up to about 50psi to compensate for high long term trim with stock tuning they were pegged on 160 Anyway good luck with your cam swap.
