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

156 traps on 93 and water...... Vids please.
Not true.
Like rx72c I have a high boost pre turbo WI setup
93 pump petrol
38psi
740rwhp
BW475
TII engine/intake
On 40psi the car has trapped 156mph on the 1/4 mile.
I don't think there would be much more hp to be made on E85 with this setup. I know which is easier to run!
Great vid by the OP!

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

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.

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.

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.

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.
