Those are 15" RT-S71s in the rear and 17" in the front. M/T 275 Radial Pros in the rear and 28x6 Sportsman S/R in the front.

You’re better off on the CTS V forums and talking with someone like Rubber Duck or Lt1z, both are math wizard when it comes to cams,

Also, I’m in soflo and I’ll be making about 800ish wheel in a few months if you want to line it up

Thanks for the tip. The V group seems to have taken the LSA platform a lot farther than the Z group. I think the Caddy folks probably just have more money to play with lol.

Nice, congrats. What are you doing to your car? Hit me up if you ever plan on making a trip to Bradenton Motorsports Park or "Mexico".

I have read enough of his posts going back a few years. I don't want to say too much, but, just no. Lt1z at least has some hands-on worth reading.
There are some people here with plenty of experience in LSA building and also airflow physics and thermodynamics and adiabatics, but yeah whatever.
Edit: What was asked was wanting about 200rwhp MORE than his current cam without chop. Yeah I'd like to see that spec'd too. Also point me to some good rear tires that can put a stock SS into the 10s in the 1/4 mi.
If rubber duck isn't available see what comp cams experts say: Tech Support (M-F 7am-7pm CST) CAM HELP® 1-800-999-0853 ; Operator (M-F 8-5 CST) Toll Free: 1-800-365-9145

I've been driving the car with a moderately choppy cam for 5 years now. It's cool and gets lots of attention, especially through the custom fabbed 3" free flowing exhaust, but the idea of having a >1000whp car with a stock-ish sounding cam seems more appealing to me now.

Car is an M6, by the way. Thanks!

Hello,
I tried to come up with a cam that would do what you want, sorry can not be done. You might as well have asked how to have the quitest camaro without any exhaust.

Simple heads/cam/pulley setup, probably meth. I’ll be over at Bradenton in a week for fl2k but not racing this year so I won’t have the zl1 haha.

Umm I’m ported blower and heads ,cam - running e-85 with fore triple pump L4 so 100% e-85 capable , only got to dyno on e-30 been meaning to go back with e-50+ or even try 100%, but I’ve read you get diminishing result past e-50 ..

I was on a mainline hub dyno and from what I gathered ,I could easlily net 825-850 wheel ..

Haha apparently we were on the same type of dyno .. pretty impressive with your torque numbers tho

There are a few guys out there who have done testing on the diminishing returns of running more than 50% ethanol. Some have concluded that more than 50-60% just taxes your fuel system without providing significant octane benefit.

I'm sure your car will make those numbers with ease, especially with a ported blower.
