has anyone tried water injection while spraying a wet 50 shot of nitrous?
keeping the boost at 15 psi.

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...

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!

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...

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...

It's not like you can't check in between sessions..
One quart on the other hand I have no problem with.

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...
