Not true. I think it was Texas speed who put that thinking to the test. I think it was on a basic bolt-on car. And the bigger primaries didn't lose horsepower anywhere. Also it made about 10 more hp up top. It's on ls1tech.

Well I'm not a fan of Texas speed or most of the pos(t)ers on Tech. I know on my Z06 which was a bolt on car the 1 3/4 made more power over the entire rpm range than the 1 7/8's. The bigger tubes made a few extra ponies at max rpm but who drives around at 7,000 rpms all day. $.02

Ok, I'm getting ready to purchase a set of LT's from Calspeed, my question is should I run the 1 7/8" primaries or the 1 3/4" for my setup.
My currents mods are only a Custom Tune, Borla XR-1 and a Volant CAI. I plan to install a custom grind cam in about 6 months. Will the 1 7/8" primaries still be a good choice to run with the stock cam for awhile? or should I go with the 1 3/4"?
