injectors for pulling

[longhorn859]

i want to get injectors that are just used for sled pulling with my truck, it wont be driven on the street. I was thinking mach 5 or similar but would ddp 250's be too big and blow up my sps62/71/14? What else do i have to worry about with going with an injector this big

With a 62mm turbo you are going to be air limited to around 500-525 RWHP. Personally I found the Formula 1 Mach 4 to be about the best injector using this turbo. Now if you want to jump up to a 66mm or larger turbo I would consider Mach 6++ or Mach 7's. But without the larger turbo all you are going to do is make heat.

i ran bullydog 8 injectors with my sps 62 for a while they were 240 hp injectors i only pulled it 1 time with them. it broke the rear end i ran them with the waste gate pluged and it would peg a 60lb boost guage so i doubt you will hurt the turbo i wouldent do it every day. as doug said you only have so much air avaliable and it will run pretty hot but if you only pulling it it probably wont be a problem.
