Brian Tooley Racing CAMSHAFT – 400 CI+ – NITROUS – BTR-35166124
Specs: 251/266 .62X”/.595″ 112+4
This camshaft is the result of years of back to back testing on 400+ cubic inch engines, mostly using TFS cathedral port heads and a Mast intake. The intake lobe made 15 rwhp more than the same exact duration Comp LSL intake lobe, and also made as much power as a Comp intake lobe with around .680″ lift. It made more power in back-to-back testing compared to a similarly spec’d cam from another leading cam company. So, to say that this cam has been rung out, is an understatement. This cam generally runs in the 5.30’s-5.50’s in the 1/8 mile in a 3000+ lb chassis and has run as fast as 5.10′-5.20’s using the same TFS 245 heads and Mast intake. Since this cam utilizes ultra stable lobes, it will turn 7500 rpm with our Platinum .660″ lift springs (SK001/SP001). Using our .685″ lift springs (SP010-16) shimmed to 1.700″ allows it to turn 8000 rpm. Most cam gurus claim .595″ isn’t enough lift for a nitrous cam, but back to back testing has shown otherwise, with increased exhaust lift showing no gains in power. This cam has gained 400 rwhp on a 300 shot of nitrous utilizing TFS 245 heads with the N2O exhaust port.

Brian Tooley Racing (BTR) – the story
Brian Tooley has been in the performance racing game for nearly three decades.
Starting his own business back in 1992 called Total Engine Flow, Brian was using a Flowdata flow bench. Shifting to Holley Performance Products shortly afterwards, he helped develop the SysteMax head, intake and camshaft packages.
Going back to working on his own in 1996 until 2004, Tooley then built Total Engine Airflow into an industry titan.
Since then he sold his business to Summit Racing Equipment and stayed on until 2010 when he decided to be closer to family and friends.
As his BTR webpage revealed, it wasn’t long before Brian was back after seeing a need for quality spring kits at affordable prices.
