This will make a ton of power! My bet upwards of 390 on dynapack! Now u better finish it!
very creative.
:vtec:
That would be awesome. I cant wait to finish it.
id run dual pumps if i were you, or find a larger single pump
Iv been playing with that idea maybe one right after the front mount.
Looks like a tight fit, but hopefully you get this working. I'd like to see the gains this gets
It is very tight. Could not go any more.




O I forgot to mention that the front mount is 3.5 inch thick as well.

yeah if you went with that 3.5" thick one you definitely need a better pump, your loses are gonna be so great if you go with the normal pumps people use.

Looks good. Omit that upper coolant tank (the one in your image that has the sight tube), retain the second, and just make sure that it is the highest point in the coolant loop.

Also, I would go from that 3.15" to a 3.0" blower pulley and also K24 crank pulley. Move as much air through the motor as possible. Good luck.

Any suggestions on the pump guys been looking but without much luck.

O and the reason I'm doing this is for different pulleys. :thumb:

I would just use the Bosch Cobra pump. It was designed for this application and is cheap and readily available.

Instead of two pumps, buy a single johnson pump. It is stronger and high quality. And very light and easy to install due to its compact size. Its the one with red caps.

Ill get a better pic later.
