Exclamation Please help with quick question before I make Transaction!

Im currently maxed out on injectors 28.8 for any type of dry shot. If i go wet instead, do i still need bigger injectors? or can i stay with the ones i currently have? I installed a Racetronix fuel pump, to help out with the demand.

Please let me know, and sorry if its a stupid question. Just trying to save cash if i can get away with not buying injectors.

When you say maxed out does that mean 100 & up duty cycle?

A wet kit does not use the injectors for the additional fuel, it does pull the additional fuel from the rail but uses a fuel jet to add the fuel.

You should be fine, but everyone's setup is different so I cannot tell you for sure that your in the clear without more details, but a racetronix pump can supply a lot of fuel and is probably up to the task.

No im not at 100%, but for any type of Dry hit i will be (PreMaf). Maf is already close to maxing also so it wouldnt be able to compensate for extra fuel as well. Given that a wet shot will not pull or make the injectors work any harder, and feeds off the fuel rail. its safe to say with timing pulled, i should be ok, right? Keep in mind i already have a good fuel pump installed.

I'd say you're probably good with a wet kit.

Our injectors are at 104% duty cycle on motor and we run Nitrous Outlet Wet plate. Our duty cycle actually drops to about 80% on a spray pass.

I was just showing that the wet kit provides all the fuel you need either pulling off the rail or a standalone and that the injectors dont matter as long as they are adequate for the motor or n/a needs. Our car is cam only and we plan on injector upgrade when we do heads. It shouldnt matter what kind of wet kit you go with just make sure your pump can keep up . I would get with whatever vendor you purchased the kit from on their recommendations for fuel as far as pump size and whether you need a standalone.

Made about 365 through a th350 and a 4200 stall. My original motor took 150hit for 100k miles plus before spinning a bearing. As long as the tune up is good then you should be OK

You won't have any problems on a 150 with the correct spark plug, timing pulled, and nitrous jetting. I also think you'll be fine with the injectors even if they are at a slightly higher duty cycle then wanted. When you shoot a wet kit it decreases the load of the maf so naturally the idc will drop.

Thank you sir for this great info... As far as spark plugs, I'll be installing some NGK BR7's, and 8* of timing pulled even if i run on a 125 or 150 shot. I know 125 is more timing pulled than necessary, but I'll be on a fixed time puller that cant be adjusted on a dime.

Should i need a TC window switch if i go with a ZEX TPS box? Similar function is it not?
