I thinking of getting a cam within the next few months. What do you guys think of LS1 hot cam. Do i need tuning or will it fine with out tuning? <img src="graemlins/camaro.gif" border="0" alt="[Chevrolet]" />

 

You have a 6-speed. You can do ok with out tuning. I wouldn’t pick a LS1 hotcam though. I’m a big fan of the T1 and B1 cams, as single pattern cams like those seem to be the hot ticket for LS1 heads (stock or ported). Since you have an M6 you’d probably be better off with a T1. You could also consider the C1 (hammer cam). All three of these are from MTI (ground by Comp).

With any of these I would recommend the 26918 springs and hardened pushrods. You might also want the 772 ti retainers for more piece of mind towards valvespring life without floating. The stock retainers will work too though if you don’t want to spend the extra cash.

 

I have the Hotcam, tuning wise it still dies, If I were to do it over(and I will) i'd go with something else. <img src="gr_sad.gif" border="0">

 

the hotcam has big time idle issues even with the M6. with an auto, it is nearly impossible. i am about to drill the TB hole. cold starts are not bad. warm are another story! it makes for a great sounding lumpy cam, but for driveability and power (top end) it makes about 10RWHP less than the T1/B1. if i had to do it over again? look above!

 

Thanks guys. How much hp/tq should i expect with the T1, B1 or C1 and at what rpm will it kick in so to speak. Thanks for the help. <img src="graemlins/burnout.gif" border="0" alt="[Burnout]" />

Do a search on B1 and T1 cams. Tony and many others on here have been posting some really good B1 and T1 dyno charts lately. The B1 starts to have HUGE gains over the stock cam around 4000 rpm or so. The T1 offers a little more midrange torque over the B1, but it is slight, and at peak the power and torque are basically identical. The B1 is almost a guaranteed to pass emissions, while the T1 is more of a risk in that dept. They are both excellent cams.

Oh...and most gain about 35 or more RWHP at peak with a B1 in an M6 with stock heads (if you have headers; gains with stock manifolds will be less)

I like my hotcam quite a bit, i have an A4 with no PCM tuning, and I hardly have any idle problems, i think it's a great cam, and it sounds mean as hell too.

 

C'mon folks..... Just do a search on Hot Cam and there is loads and loads of info in here.

The Hot Cam can be made to work with stock heads as well as any other <228 .05 duration cam.

In order to figure out how to get it to run with your combo, do the search and infer some other common concepts.

here is a graphical comparison of leading cams.
This is done with desktop dyno.. its calculated
data..

I have the hotcam kit and it was great for the
price.. $418 and it came with springs and gaskets
and a crank bolt.. I wanted everything at once.

here is a dyno of lid,hotcam,exhaust through
stock manifold and cats..

Ihave the hc with ported heads and mac headers with orp and ls6 intake.no problems here.idling @950rpm.didnt need to drill the hole.needs tuning or programming though.Im stuck at 375rwhp.All I can say about the hotcam is it works on some m6 cars and it wont work on others.definantly not for a4 cars.If had to start over again Id go with the thunder cam. <img src="gr_grin.gif" border="0">
