Big Turbo Using Nos To Spool It.

[MJTru]

I have a power fc. I also have a PS2000 but never got around to using it. Ill have to ship the car miami to have it tuned. But im very intrested in getting some boost off the line. Big turbo or not. STATUS can you go through how the system would work. Throttle switch and rpm switch. i have two gtrs and would be intrested on how the system would work. Even if i was to do it on a honda civic. I just want to understand how it works and try it at some point. I understand shooting NOS will bring in a laggy turbo much faster like in the video, but using it to build boost on the line is my interest.

works killer best mod ever for big laggy turbos. even a 50hp shot can bring a big turbo on so much earlier.

Full throttle switch, arm switch and rpm switch are necessities, a decent ecu should have it there ready to go.

Status have u setup many dry kits where the ecu supplements the extra fuel required? If so is it tricky to get the tune right as apposed to using a fuel solenoid? My fear is on the off chance the fuel solenoid doesn't operate as per usual your tune will go lean and hurt something.

Personally I would use the NOS to get the car off the line while helping to build boost, have it set to start the NOS at a preset throttle position then a boost switch to turn it off once boost is where you want it, if set up right you can also use it to regain boost after gear changes

This can all be set up easier through a good ECU using the inputs that are already in play

This is where im a little confused. Wouldn't the NOS damage the motor in nutral.

Say i have the system set up. Now at at the line staging the car waiting for the light floor the car revs are maxed out lets say at 8k fuel cuts but now NOS is being dumped and like you say until boost is reached. Keeping in mind im not just dumping NOS but a mixture of NOS and fuel like the kit i have. Wouldn't this damage the engine.????

Or do you mean use it normally when the car is floored off the line.??

I can see a lean effects right away.

Maybe theres somthing im missing here.

I think where im going wrong here is using NOS to bring in a bigger turbo whiles in motion. The lag spot vs. Using NOS to build boost off the line. In nutral free reving. = cant be done. Well at least in my head.

Via a output to switch it on only after revs are at say 4000rpm (or high

enough not to bend a rod..)and

Tps is at 100 percent

Then switch it of at say 8psi and let physics do the rest

I had a dyno of my mates rb30 with a 3540/t04z 1.06 with a 75 dry shot..

power up top was decent . Midrange was absolutely incredible

Is this method you mention building boost off the line. Or is it whiles the car is moving. Im just not to clear about this after reading. ??

you dont need it off the line generally its easy enough to make 20-25psi with a decent launch strategy in the ecu...with a manual

yeah we do mostly dry so that we have 100% control.
