He'll I've heard of people running 25-30 psi on just straight pump gas (93 ) on a carbed setup which I thought was absolute bonkers, apparently it's all in the tuning , ESP the timing map

Out of curiosity what cc are these injectors?

156 traps on 93 and water...... Vids please.

No vid of 156mph pass that I know of but here's a slower one. Best ET to date 8.86@155mph.

^thats awesome man! Sweet 323

Lol this is probably my favorite rotary car of all times.

do keep in mind the car is approx 2300 pounds... this is not to take anything away from the Green Brothers performance. i, too, think they have not only have they gone really fast and but they have shared a lot of the details on our board.

i was especially interested to learn about their tuning process.

if you are not familiar w them look for their threads/posts. good stuff.

howard

agreed.. i would like to have a video from you from like a 40-130 while i post the same video to see the results..... I have one of a Zr1 from 40-130 that i was going to post up between his car and mine..

your asking for trouble right there

You and Rice are outliers, in terms of what you are willing to push on WI.
While impressive, your example is not representative of the general case for water injection.

What do you mean? Are there others that have attempted to run pre turbo WI at "extreme" pressures on pump gas, without any success?

Not arguing what you are saying, but I am intrigued if others have attempted to follow the lead and have failed.

goes very well :)

Has anyone answered how much water is being injected?

About 1300 or 1400cc at 20psi from memory.
Yep, car is 2400lbs in street/race trim

more videos please, in car etc!

Takes off like a mf...

does a couple ppm of additives make much difference? How pure is the distilled water?

Its only $1 a gallon and will not clog the nozzles as easy as drinking water.

Plenty of people have tried to do what Rice and JBZ(and this particular car) are doing and failed, not because the theory is flawed but because the execution is difficult and the consequences are grave.
The general population tends to trend behind the bleeding edge. Moreover, most of the cars here are pure street cars. Most members don't have the time/money/expertise/tuning-ability that rice and others have.
Most people pushing anything higher than low to mid 20psi are going to be running meth and/or race fuel.

30-40psi on pump w/ straight water injection possible? Sure.
Suggested for your average consumer? Absolutely not.

Most people can't push that much boost on anything reliably. Period.
It takes a lot more than some water injection to run that much boost. That's the point I'm trying to convey.

I agree. Peter and I have talked lots over the years and set up my car the way he recommended. I Ran 35psi last fall with about 1200cc's between pre turbo injection and a nozzle at the Tb elbow. Its very tedious when tuning and no room for error especially with the fd's weak spots in the rotors.
But spinning 5th gear easing into boost at 40mph is nothing to brag about ITS SCARY! But I just had to do it once.

^^ you did that on your precision turbo?

Holy rocket ship

I do not run distilled water.

Like I said before. I did this many years ago now and have done it for many of customer's who enjoy HIGH HP rotaries that are more reliable than most. It isn't rocket science. Good ignition, lots of water and you are half way there.

Tap water?
