I went 158 on the 118 mph 1/8 run....but it had the same tune up as the 125mph 1/8 mile run but spun bad....just put that 125 mph in as a point of reference for power purposes...

I think everyone should add in what compression ratio and timing they are running. Some people may push water at 20 lbs on a 10:1 cr engine running 16* of timing and others may be fine at 25 lbs because they are running 8:1 cr with 12* of timing.

I don't think you can look at it strictly in terms of amount of boost, you need to look at the power level. When LastLS1 says 23 psi, Andy is basically saying like 1200 hp or something right?
I'll say 155+ in a heavy car, and 160+ in a light car.

You can push water at 130mph if you try.
All depends on your definition of pushing water, moving a couple ounces or blowing a couple quarts into an overflow. Pretty safe to say that over 1000fwhp is when you are going to start having problems if you race the car often.
I'm starting to see some carbon between the head and block after last weekend, I havent ran much 1/4 mile this year either and its really not moving a lot of water, But when you see those marks between the head and block there its coming soon.
I have noticed that its a cumulative thing, more passes you make (or more you beat on it in general) its going to start doing it worse and worse. If you make 20 passes a year you can get away with a lot more than if you make 100 thats for sure. But I'm kinda used to it, kind of a bummer since when I see it I dont want to push it any harder..

I kinda wish the Ohio Boys would chime in a lil since the did so well last YR (Both of them)
On 4 bolt setups.
I think them holding in the info is hurting scene more then helping them out, esp since they both have moved onto 6 bolt setups.
I dont have the extra $1900 for the block and $800 to have the extra bosses on the heads right now.
That $$ can finish my car and buy my BS3.

I don't think there is a secret they just had a water capture tank installed. So they were pushing water.Their block and heads were o ringed with oversize head studs with copper gaskets. Not much else you can do. If it worked they wouldn't be switching to 6 bolt heads. You can only go so fast with 4 bolts.

I have a three quart header tank thats stays pressurized, unlike a typical puke tank it will drain right back into one of the heater hose fittings on my EWP as soon as you let off and the pressure drops. Doesnt prevent pushing water at all but now I dont have to drain or refill anything betwee passes. Luckily I havent needed it this year yet, but the cool weather is coming so I'm sure I will soon.
Look at a C5 cooling system and you can get an idea of what I'm doing..

Steve and Mike pushed water in the low 8's and faster, and that was with 1/2 inch studs and o-rings. But they understood it would happen, more than most would, so they have bigger overflows etc. Steve told me a few weeks ago he has not pushed any water all year with the 6 bolt ERL setup... very nice.

Its not on the car now, its an aluminum header tank from a newer stang (got it on eBay) and some braided line. It just works like the header/expansion tanks used on quite a few cars, like a C5.
Its a very simple setup, I havent done much testing with it, when I'm sure it works 100% I'll let everyone see it in all its glory lol.

sorry for my ignorance, but since I have never had an issue with pushing water what should I be looking for, or how do I know that I am pushing water. This will be the first car that will even be capable of doing it. all the other turbo cars were little VW's and MR2's
