Comp Cams NSR 127200 Cam Test by Brenspeed


Brenspeed / Comp Cams NSR 3V Cam Test

We have installed a lot of 3V cams over the last couple of years and came to one conclusion. They make good power but the installation cost can give most customers sticker shock. The reason the installation can be so costly is because of the labor involved with changing the factory valve springs. It can be a long process and is very time consuming so we had an idea. We went to Comp Cams and requested that our stage 3 cams we have had great success with be slightly modified to be used with stock valve springs. So here we are releasing our NSR (No Springs Required) camshaft set...

Lobe Separation: 115.5 Degree

Our original Stage 3 cam test we performed long ago used a manual trans GT that had about every bolt on part possible. We decided for this test to use a lower producing automatic GT. The 2007 GT for this test was running a C&L Racer intake along with our custom tune. It produced 283 rwhp and 305 ft. lb. torque with the stock camshafts installed.

The idea behind the new cam design is to reduce cost yet provide a nice power gain. The new cost of our NSR 3V camshafts will only be $649 a pair and with installation only taking around 4 hours you can get into a cam package for just under $1000 installed!

The NSR cams worked great! At 5700 RPM's we picked up 24.95 rwhp, at 6,000 RPM's we found a 27.6 rwhp gain, at 6,200 we found a 31.3 rwhp gain, and at peak vs. peak the cams picked up 20 rwhp! Just like the Stage 3 cams peak torque numbers stayed about the same as the factory camshafts are already optimized for torque. We believe even though these cams were slightly detuned from the Stage 3 Comp Cams they still provided enough airflow to satisfy the engine. These cams will make many customers happy as the price and installation cost when combined is half of our Stage 3 cam package.

Ordered the cold air and tuner combo. Best tune I have had. Really woke up my 5.0
