Default what size injectors

Im thinking my injectors are starting to let go a little and if i replace them im not sire what size to go with for now, i eventually want to run 125 or 150s but budget is tight and i cant afford a clutch and turbo to go with it if i leave the wire tapped on my edge. Was thinking i could get either ones and untap the wire on the pump and run the edge for just timing but then again would i be better off with something smaller?

If I were you I'd get a clutch first. You can run 150's on stock turbo fine, I did. but I'm assuming you have an hx and not an hy, because of the trans.

I think you would be better off upgrading to a Valair Clutch first then upgrade to some Big Dawg Injectors.

Yeah im not sure whether to go dual disk or single, plans for the truck is a weekend drag warrior, daily driver sitting between 500 and 600 hp. I hear dual is better for holding power but makes slow shifts and sucks daily driving and a single can be too grabby for dd at that power level and makes sacrifices for drag racing as far as slipping the clutch when leaving the line.

well you can turn the power down when dd and it should be fine. I like southbend clutch myself. No matter what you need a clutch before adding any more power. 150's and a stock turbo is asking for issues. Just save up and get a turbo and injectors once you get the clutch taken care of.

What bugs me is i have no clue what clutch is in it, the po said when he bought it the seller said it had a new clutch at 110,000. Ive got 180,000 on it now and it holds awesome with no slipping but i dont really want to find out it has a big clutch in it when i blow money on a replacement when i didnt need it. Pedal feels a little stiff, it lets me slip it and it makes a little noise starting of in 2nd. Being it can slip i dont think its performance but pedal pressure and the chatter makes it seem possible i guess

you could always get some 125HP injectors and turn your box off if your clutch slips. It would be best to make sure you have money for a clutch before you get big injectors. We have about 80 sets of injectors in stock for the vp trucks and are a master distributor for Valair. Let me know if we can help
