I have a new Youtube video:

This is a copy of a post I did on another forum: Here is an update on my fuel system. I have given up on an auxilary injector. I tried 2 different approaches, including the Fuel-It charge pipe injector. My tests with a clear plastic pipe and a leaf blower show almost no vaporization, just a...

Thanks for the suggestions. I'd like to tap off the existing fuel rail, so the pressure is what it is. I emailed the "Fuel-It" people and they claim their injector will work, so I'll give it a try and show the results here. Can I pulse width modulate a solenoid fast enough to control a...

I put together a charge pipe injector test case using a Bosch EV14 compact injector. I didn't use the Deka recommended above only because I found a perfect holder for the EV14. I used a 360cc injector with a cone spray, driving it with an Arduino + MOSFET that pulse width modulated the...

Port Injector?

What is a "PI injector"

Thanks for the suggestions. If I go with an aux injector, I don't plan to use an off the shelf controller, but instead do my own control with the existing Arduino. The coding will be pretty simple. I'll probably have a fuel table for the one injector, based on rpm and boost. Look up...

I think I finally got the VESC reliable. It took a lot of trial and error and fooling around, but in the end, I believe my setup is ending up better because of the VESC. I wanted something that I could just get in the car and drive, and not worry about the supercharger or battery (or fluid...

Do you think a single injector will provide good cylinder to cylinder fuel matching? I've been thinking an FMU may be better at this, as it hits all 4 injectors the same. I asked ChapGPT and she(?) says the single injector will be fine. I'll probably start with the combination and then...

I upgraded the fuel pump when I ran nitrous, so I'm good there.

Check out the picture at the top of this thread. There is a 90deg silicone hose on the TB and a short charge pipe feeding it. I'm thinking of welding an injector bung on that charge pipe. It will be at an angle pointing downstream. I've read that you get better fuel distribution if you...

I'm reading about adding an aux fuel injector into the charge pipe and controlling it with the existing Arduino. Can either replace the FMU or smooth out and augment its response. Obviously not as good as a new ECU, but maybe good enough for 6psi, especially if I add a fail safe to shut boost...

I'd like to avoid adding another fuel/liquid to store, replenish, rely on. I couldn't find room under the hood for extra water storage for the intercooler, and I'm trying to keep it close to a box stock s2000 for ease of everyday street use. What do you think about injecting gasoline...

Unfortunately, the ECU on the early S2000 cannot be tuned. I'd have to replace it to tune it. I turned the boost up to 4psi today and drove for a while. 4psi totally transforms the way the car drives. I'm thinking I may limit the boost at 3 - 4 psi and use the FMU for a while, but it needs...

The motor coupling bolts to the blower input and clamps to the motor shaft. The all-thread rods align the coupling, then the aluminum box screws are tightened up which holds it all solid. I think the motor is putting out about 14hp at 6500rpm. You can see one of the cooling fans at the far...
