This a great chart. I'm a big believer in keeping the supercharger in its efficiency range .
Heat is not power !

That's great data. I'm right in the sweet spot with my setup as I had calculated.

2.50 on stock lower puts me right on the verge of the SpaceX program.

Still gonna send it.

you can have all the boost pressure you want if it is too hot/inefficient it's taking power. not adding despite what your boost gauge says.. It is all about efficiency IE bang for your buck. one tip is cold is good. octane is good.

 

[fubar569]

Just the tip?

My buddy has a Vortech on his stroke 392. He was over spinning. Put a bigger pulley on and went faster. Gotta make it efficient.

Where would the incognito lower fit in on this?

Your's would be close to the 3.1 with the 8.18 pulley.
