The newly machined and modified P7100 housing is available with Rocken Tech’s 16mm P7100 pump plunger kit which goes to 1500+ hp.

 

How many cc's is that?!

 

i'm going to take a stab in the dark and guess ~750cc's



or more information.....

 

1200-1300+cc

 

Why would you ever need 16mm plungers and barrels? Most of the mod trucks in the 3.0 class run 13mm with 1,000+ cc's

Where are these plungers and barrels made?

 

16mm P/B is a big step up than 13mm or 14mm p/b can do. Only those who want to be on the top of the game will use the kit in this P7100 category. Initially it required you to modify your own housing. Now it provides the modified/machined new housing for use with the kit. Here is the link: Rocken, Tech, Diesel, fuel, Injection, Test, Performance, 14mm, 16mm, Pumps, Nozzles, Parts

 

I understand the big jump from a 13 to a 16. the quick injection rate would be one of the biggest benifits here. Most super stock tractors and prostock tractors still run 14 mm pumps .

Also how is the quality of these chinese units your selling? Honestly I have not heard a lot of good things about them.

 

There have been more than a dozen of the 16mm (P7100) pumps out on the fields, and they are very successful. Rocken Tech's most products are processed, assembled and final processed in Northern California. The quality of the performance parts are proven top graded. Here is the phone: 707-658-1915

 

Funny...
When I did some research on your outfit with some of the notable shops that build alot of the local pullers they all said the same thing.....Stay far away from Rocken Tech.

So I will ask the source....
Who are these pullers using your pumps that are so successful?.

And I agree with Dave....
Every Cummins equipped Dodge/Ford/Chevy puller is either running a 12mm or 13mm
P7100 and the hot tractors are running 14mm's.ANYONE beyond that is running a Sigma and would not run a 16mm P7100.If you want to play with the big boys,you need a weapon that will handle the job and that weapon is not cheap.

 

16mm thats way to much
