All kits are pretty much the same. It just depends on if you use jets that are rated RWHP or BHP.

i purchased the wet kit from dynotune from a while , i think the maximum solinoids HP is 175HP , so i want to run the maximum for the solinoids , i bought two jets N61 and F34 , so all what i want to be sure if those jets is for 175 , because 01m6ss said they are for 150HP ,how can i be sure ?

I recently asked Dave at DynoTune nitrous if I could run a 150rwhp shot consistently on their smaller noid..here was his reply...

If you want to run 150 all the time at the rear wheels I would recommend our larger solenoid.THe smaller would be right at the edge.

When I use this calculator, http://www.robietherobot.com/NitrousJetCalculator.htm, and put in a size 62 jet and round up, it says that is for a 175BHP or 150rwhp. Which is about right from that post I made on #3.

So, the 61 jet will make good power, but be close to maxing out the solenoid. That is why I am replacing mine.

sounds good , how much the stock fuel pump pressure ? if i installed walbro 255 fuel pump how much will be my pressure ?

jetlag

iTrader: (32)

It still should be around 58, but it will be more consistent and able to keep up with the system. I think they are rated at around 550rwhp.

The Racetronix kit + wiring harness is the worth the price...around $230. Easy install.

i bought the walbro kit and this is the picture for the pump , if fuel pressure go arround 58 i should change jets ?

jetlag

iTrader: (32)

Stock fuel pressure is 58.

Did you buy a kit or just the pump by itself? I like the Racetronix kit because it comes with a stock flex hose, unlike what comes in the Walbro kit that is a regular rubber hose.
