Tell me what you think:All done with a Kenne Bell

Here are the old numbers 450.7/ 525 88 degrees 15#

With C&L upper Plenum, metco idler bracket, 72 degrees 16# (17 at 5500rpm)

476.5/537

I will scan the dyno sheets As soon as I get to my scanner!

 

Impressive gain.
Are both number corrected to the same standard? Was the extra pound of boost from the plenum alone (no pulley changes)?

 

That's what I wanna ask; is the extra pound just from doing the plumn?

 

The Dyno is SAE corrected and the extra pound of boost was with the intake. Now I put the metco idle bracket on a week after the intake and saw a .5- 1 pound at 5500 short time at 17#. The weather was 10 or more degrees cooler. So Take the information with a grain of salt.

This 476 hp is on the stock block / bottom end.

 

That is stout...
