I have 450cc dsm blue tops and assuming I have around 300hp.

im sure my injectors are lil different from the dsm 450's, but i run bosch 42lb injectors which are 440cc and they dont max out til around 400hp, so i dont see why u couldnt make way over 300 on the 450's

yeah, 300 is around the peak. I have 460cc injectors and am running like 250 and I still have room for more fuel!

look for old turbo dsm injectors on ebay

How many injectors are you running? Hp to the wheels or at the crank? 4 injectors @ 450cc are near or at 100% duty cycle in the 300whp range. I've seen as high as 320, but the base pressure was around 55psi and most fuel pumps are not happy about being at 85psi.

Got any videos??

I heard about that. What type if injectors are they? Resister box needed?

thanx for the replys.

They are bolt ins for DSM's, so anything you'd need to make 450's run, you'd use to run 550's.
