I know alot of guys get Eaton S/C ported (especially Lightning guys) however, does anyone know of a place that does the whipple twin screws? Im trying to get as much power out of my truck with keeping 8PSI. Im not familiar with how much power you gain out of a port job on a S/C but Im looking at different areas in which I can make power without changing pullies this is just another idea.

If anyone has any info please inform!

Thanks!

 

Try giving Stiegemeier a call. They are the porting experts.

I sent my KB to them to be polished and asked about porting it.
They do not port any twinscrew blowers.
I don't think anyone dose.Haven't heard of anyone having anything other then a roots blower ported.

I would just add a pulley.
It would have the same effect on the motor. Your still adding more power to it.

Phil is right on. Add a smaller pulley and reap the more power and tq results with out having to worry about porting. Plus the whipple is more effecient and creates ALOT less heat than the old "Heaton" blowers when they are spun faster.

Yea, I was just trying to stay at 8PSI. Thanks for the replys guys. Im trying to go 8PSI but make around 450/475RWHP in other ways.

 

Why?
That's an awful lot of power on a stock block!

Phil

 

You must really want to get in the vented block club with that kinda power on a stock block.

Wayne

 

Stock block is good up to 475RWHP on a excellent tune. Anyway, plan is if I blow this block, I go built block with around 700-800RWHP.

 

Somebody lied to you. 475RWHP is a stock block limit on a stock bottom end Lightning and that is pushing it!

Na Check out JDM and their SALEEN truck.

 

More power to you bud!

Wayne

 

yea well heres hoping anyway! hah

 

Do like I did,,,just pump her up till she blows and build it better.

Have fun with it....

Phil

 

Make sure you already have your extra short block so that you're not down too long when you have to do the changeover.....
