30-3300 psi

 

Hi I'm curious as to what the pump is preset to in a 30-3300 kit I know they call it a 200psi pump but is it preset to 200 or 150 like the earlier version?  
The reason I'm asking is I have and use an older kit the 30-3000 and they call it a 200psi pump but it is set to 150 psi and I want to get one of the newer nozzles with a 1000cc jet but want to know if the psi has changed so I know if 200 psi is required to get 1000cc as my jets the biggest was 550 

Also wonder if a person could drill out a smaller one or is there more to it then just drilling?  My kit had come with 125 and 315 and 550 and my extra nozzle kit came with 315 and I think 630 could I take one of the 315 and just drill it bigger if so what size of hole for 1000cc I'd just buy one but live in Canada and can't find no stock just for the jet itself without buying a whole nozzle kit.

Pump pressure will ultimately

Pump pressure will ultimately depend on the nozzle size used as a smaller orifice with more restriction will have higher pressure and vice versa.  If you really want to dial in the nozzle flow, get out a beaker and test flow it and adjust the pressure to get the flow you want.  And no - you can not simply drill out the orifice.  The orifice is a finely machined surface.  A regular drill bit will destroy the finish and absolutely ruin the spray characteristics making the nozzle useless.

Ok thanks no drilling I got

Ok thanks no drilling I got it.  But what about preset pressure on the pumps in the 30-3300 kits is it set the same as the 30-3000 kits? Guess what I'm after if I get a 1000cc nozzle now that is v2 and use it with my v1 pump will I still get 1000cc.

I don't know but you can

I don't know but you can figure it out for yourself doing what I described by flow testing the system and then adjusting the pump to achieve your desired flow.

You don't know if the pump

You don't know if the pump that came in 30-3000 was preset to 150psi or not and if 30-3300 pumps are the same?  Can you tell me if I buy a 1000cc jet will it fit my nozzle off of the 30-3000 kit? 
I realize I want a 1 point in afr change with the kit on just looking to get the right jets the first time around in it.

There were different

There were different iterations of pump so no, I don't know what pump you have nor can I really know exactly what pressure it's going to make but like I keep saying, they're adjustable. You realize that you need to see a 1 AFR point change to know you're injecting roughly the correct amount of water/methanol. So you plumb everything up and do a test hit and then what? If you don't see the full 1 AFR point change, what would you do? You either increase the jet size or increase the pump pressure to get more flow. The system may require "tuning" so my advice is to stop worrying about what the pre-set pressure is and just get the big nozzle and you'll more than likely have to adjust the pump pressure so once you adjust it, it's old pre-set pressure setting is irrelevant.

Uh ok I was also asking if

Uh ok I was also asking if the 1000cc jet would fit the same nozzle guess I'll just figure this out myself thought this was a support forum.....

Sorry misread your comment.

Sorry misread your comment. The nozzle design has always been the same.
