Nitrous and Water Injection

[Mart160plus]

Evenin\' all.

Been perusing, whiling away the hours \'til I can get myself a rotary, and the following questions come to mind :

a) I haven\'t seen anything about water injection in these threads (OK, I\'ve only looked so far). This was pretty big on the GT-Fours to reduce temps and avoid detonation, is it not something anyone indulges in with a rotary ?

b) Haven\'t heard any mention of nitrous either. Anyone been down this route ??

Enjoy Rotorstock folks, look forward to seeing the pictures.

Mart. :cheers

There are a few cars running WI - mine is getting fitted as soon as the engine goes back in (having had the kit for months now).

It is generally regarded as risky to put nitrous on a turbo\'d rotary, how much of this is down to fact and how much general scaremongering I don\'t know.

[bobster]

There are a few rotors throughout the world running N2O with varied success. I think it just depends on how it is set up.
From what I have read some of the big gas installs (100+bhp)can cause problems, because the rotor tips don\'t really like the sudden drop in temperature.

But like Robbie says this could just be scare mongering

My friend has just had to do a full rebuild on his Supra twin turbo due to the water injection failing, the solenoid valve stuck open and flooded the engine causing muchos damage.

Both of these are valid for a rotary. It\'s an otto cycle engine after all.  It really comes down to the fact that people are only just starting to push the limits on rotary engines and getting to the point where WI is a necessity rather than a niceity.

I believe that a shot of no more 50/60hp is fine even for a rotary..if you set up the nitrous correctly (ie with a nitrous progressive controller ) you should be fine..A friend of mine will install such a system in his FD in June and maybe I\'ll follow and use it in my FC..
Ah I forgot to mention that wet nitrous systems are recommended for supercharged and turbocharged engines.

Cool, sounds good George, let us know how you get on.

I don\'t know what problems rotaries have with detonation (if any), but anything that cools the combustion cycle can only help with these hot engines.

Cheers.

This drop in temp is always good but there are some people who believe that this sudden drop in air  temp(if i am not mistaken, the nitro lowers air temp by 75 degrees) is not good for the rotary engine..
Try this site, it has a nice article about nitro and rotaries..

All I ever needed to know, thank you !

[Black7Conv]

You are welcome
If you decide to install a wet nitro system and you do it before me, plz let me know..

Need to buy the car first. I\'m sure 400 bhp will keep me honest for a while but I\'ll let you know when I plan to go down the nitrous route.....

It\'s interesting that the article doesn\'t recommend N2O with turbo\'s because of the boost creep.

Surely there must be ways of combating boost creep?  I wouldn\'t want to have turbo OR N2O

I see that he is persisting with running both though :confused:

[Black7Conv]

Chris the best way to eliminate boost creep is an external wastgate..but it\'s an expensive way..
If you set up your car correctly and you have all the necessary parts, nitro can help your turbine spinning in lower rpm..
I am a bit persisting because I have seen turbo cars fitted with nitro where sometimes they lose traction even in 4th gear and they have full power in the turbine even 1000rpm lower...
I\'ll see if my friend\'s FD can cope wth the extra \'nitro\' power first and then I\'ll take my final decision..hehehe  

[chrisBoid]

It\'s good to know that there is a way, even though it is at a cost.

Please do post a report of how your friend gets on, I\'m sure there are a lot if intersted people on this forum

I think that N2O+Rotary is a case of knowing what you are doing.

I know of guys doubling the hp of a non-turbo rotary, and I also know of guys getting amazing hp out of a turbo rotary+NOS.

//www.evil7.com \'s RX-7 will be an example of how to run NOS on a rotor, should be going in the next few months.

Don\'t be close minded, you can get it all to work.
