i guess no one is crazy enough to try it https://www.nopistons.com/forums/pub...IR#>/smile.png

Probably because no one is crazy enough to run nitrous on an RX-7 period! I have heard of a few people running nitrous, but it is few and far between!



Tom -

How long have you been running your homemade system? Did you base it off of the DSM design on that site? Anything you needed to change to adapt to the 7? What boost level do you have the water injection coming on at? Did you run the pressure sensor off/near your MAP sensor? What did you use for a reservoir and where did you mount it?

I almost exclusively drive my stock 7 at lapping day events, and this could be a great "reliability" mod for my car.



Thanks!

I've been running 19-21 psi on my motor now for a while with the auquamist system, I've done around 100 drag launches and around 200 hard pulls and my engine is currently still alive running pump gas. I'm very pleased with it.. I've also found that 1qt of water lasts a long time as well. We'll se if it can save my engine from the T70 I'm slapping on there soon enough... https://www.nopistons.com/forums/pub...#>/biggrin.png

Have you done any road racing? I'm curious as to how much water the system would use over a full day of 20 minute sessions, probably 8 or so minutes of each session being at WOT...



Ryan

actually it's a lot more common then you would think, heck one guy with i believe a TII is running like a 175shot or something, he's only on the other forum though. 50 and 75 shots seem to be a lot more common then you give credit for, and dont even say nitrous isn't good for rotaries cause then i'll have to find that guys page so he can teach you about how well it works if you know anything about nitrous itself.



kevin

but is it possible to run both nitrous and water injection?

i know that you don't gain hp from water injection, and that its only to reduce detonation.

so imagine you spray nitrous and water at the same time, isn't that going to send ice to you motor, or is it impossible for the temp to go below 32F?

water injection does increase tork at the same boost, but only lets you increase hp with more boost...



I don't see it getting that cold with the NOS.. I hate NOS by the way.. I want my power all the time every time and you can do that with the right turbo and no stupid blue bottles...

you set the water injection to come on at what ever psi you want, I have mine come on at 12psi... 1qt should last you all day, but it's going to depend on what size atomizing tip you use etc... It's not like you can't check in between sessions.. https://www.nopistons.com/forums/pub...IR#>/smile.png

Totally agree, but the car is packed enough as it is when going to the track, if it's going to use 5 gal of water over the course of the day, I don't think I have that much room in the car. Hmm, time to buy a track trailer... https://www.nopistons.com/forums/pub...DIR#>/cool.png



One quart on the other hand I have no problem with. https://www.nopistons.com/forums/pub...#>/biggrin.png

lol.. just use bottled water and not tap water since it is much cleaner and won't build up deposits in the water jet tip... I'm sure you can steal some from sombody at the track or maybe even buy it there.. https://www.nopistons.com/forums/pub...IR#>/boink.gif
