Im making 355rwhp and thinking of adding a75 drt shot to it.Will I need to upgrade fuel injectors and pump and if not can I get away with a 50 shot?Is the 50 even worth it?The car is 98 and I believe the have 28lb inj.

if u have 28lb injectors u'll be fine on a 75 shot, u'd be fine on a 100 shot. yes it's worth a 50 shot even tho u might not feel it at all it'll just seem like ur car is running very well.

I do have one question tho, ur title says "75 dry plus cam"...and ur thread has nothing to do with a cam...are u wanting a nitrous cam? u don't need a "nitrous cam" untill ur spraying BIG, IMO 200 shot or more.

I have a cam TR224/112cam.I was gonna list all my mods then thoughht it was easier to just put down the rwhp.

 

I have the same cam w/heads 407/387. I added N20 70 shot and ran out of injector. Added 30svo's upped to 100 shot, ran out of pump, added a bap and upped to 125 shot. Ran out of pump. Added a Walbro 225. New injectors next.

I did not know nx made adry kit.Wher did you get it and how much.Ive been looking at harris dry kits seems like good quality and price is great!!So in all with the hp Im putting down(355rwhp)I should be ok without upgrading fuel pump and injectors on a 75 shot dry

 

Nitro Dave has a number of halo kits depending on your vehicle. Work great. Nitrous Outlet has some great kits avalible.

Ill give him acall soon I saw a kit on a pace performance catlog it had a spraybar and was nx.It said 50-75 shot ls1.I know most will say to go bigger,but for now this suits my needs I dont want to upgrade pump injectors till I add heads.The n20 is just there for that little extra

 

You should be okay on the 75 shot, on the 100 you may need to upgrade the injectors, you can log the injector duty cycle to know for sure. Our dry kits include a free upgrade right now:

Let me know if you have any questions.

Thanks,

John i think you will be ok on a small shot even though i would rather get the fuel upgrades than not. Plus fuel up grades and a dry kit from hsw is still gunna be cheaper than heads.We still need to log that thing again on the street we can double check then.
