You can play with the calculator and see where bumping the base pressure up will get you. You need to remember that you will eventually get to the point where the internal pressure relief opens as well. Depending on which generation 450 you have that pressure relief can be as low as ~90psi.

The right way to do it would be to do the pumps and the ID1700x's. Do it right

 

PM me ID1050X for 07' s2k with PnP shipped to 33186?

 

i get it.. just sucks that i just bought the 1300 and 450....

 

They were enough for your old goals, not the new

I feel your pain, I have gone through numerous levels of the build process too!

 

And here I am with 1000s and a 340 pump, shopping for 1300x and a 450... maybe we should talk.

 

anyone use the ID1050x ? any input or pretty much just new version ID1000's?

 

hit me up...

 

Will give ya a shout tonight when I'm home from the office.

 

Plz share your conversation here haha. Id like to know what the next step up from 1300 and 450 are too

 

While it is replacing the ID1000, it is 100% different. Obviously the flow at the same pressure is slightly better, but it also has better low pulse width behavior than the old ID1000's as well. Albeit getting the ID1000's to idle and drive well shouldn't have been a problem for anyone here with a competent tuner. If they are big enough for your goals I wouldn't hesitate to pull the trigger.

ID1700's and a dual pump setup. Unless you get lucky and can get your hands on a brushless system like I have
