I have a 2000 M6 Camaro. I will be running Mac Headers, Y pipe (gutted cats), Hooker Catback, Whisper Lid, S2 TB...and of course a cam. I actually already bought a used T1 cam...but, I am not sure if I should sell it and buy a B1 cam. I used to run a GTP 220 112lsa, idled fine. How do these cams perform on M6 cars? Anyone run both cams? I am not looking for T1 is for M6 and B1 is for A4 answers. Actually, my TB is already drilled out a little (idles around 800)...I am thinking of redrilling to the stock hole size for the TB if I go the B1 route. Last year, I installed the GTP 220 cam and the headers at the same time. I wound up running really rich and would smoke at WOT...I dynoed only 350rwhp (with pulley,lid,cutout, mac headers w/ ORY, and cam)....it is funny, because with just pulley, lid, and cutout I would pull 320-325rwhp cars pretty consistantly. Would the B1 cam lower my chances of running rich?

Was the smoking related to a specific rpm in general or did it just like to smoke on the cam. Maybe you could of leaned the car out some? How were the A/F ratios on your pulls?

 

It would smoke at WOT only. I had my car dynoed at the "Dyno Day" at FASTech. I don't think there are A/F ratios on the dyno sheet. Also, my SES light was on from Multiple/Random Misfire....could this have hurt my dyno numbers?

 

It running rich was NOT the cam's fault. There are MANY people running the T1 cam without fuel/air problems.

What were your Ltrims at idle when you had the extra rich problem? What were your O2 readings? Did you use a wideband on the dyno and if so what did it say?

T1 for M6 cars. (Sorry, I just had to!) <img border="0" alt="[devil]" title="" src="graemlins/gr_devil.gif" />

 

I don't know what my A/F ratios were or 02 readings. Any other suggestions?

 

I was throwing the "Mutliple/Random Misfire" code when I dynoed the car. Could this have affected my HP numbers?

 

Hey James I've got an 01 ramair m6 car with just about the same mods you've got but no tb.I'm turning 384 hp/393.7tq on the dyno.The cam sounds like a big block idling.I love the 2nd gear stump the gas,put you in the seat feel <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

which catback are you running?

 

If emissions or idle quality is a concern go with the B1. I had stock TB hole with stock heads and put down 391 RWHP.

 

I'm running the B1 with stock heads and long tubes with the rest of the bolt ons and getting 361 rwhp. Unfortuneatly the cats were on when it was getting dynoed. Idles at 900 rpms from a cold start up with abosolutely no problems what so ever. No SES lights at any time and sounds pretty much stock with a mild lope.
