Any minute now, somebody's going to say "DO A SEARCH..."
But this forum has been pretty dead lately, so we might as well kick it around a little.
The only absolutely safe shot, is no shot. Anything can go wrong...
With that out of the way, the 85 dry shot is relatively safe.
Wet is a little riskier, because the intake was designed to flow air, but not fuel, so there is the risk of puddling and spectacular backfires.
If you are monitoring the o2 readings, and know you're not running lean, then a 100-125 is reasonable. That's if you have the necessary safety devices - fpss, window switch, etc...
I'm running a 150 dry shot, but it's only been a few passes. Tuning is a royal pain with a large dry shot.
Ok, I think that about covers the basics...\'98 A4 Camaro v6->v8 conversion, and STS kit next<br />v6: 13.6 Powerdyne, 13.2 150 shot, 13.8 120 shot, 14.3 85 shot, 15.7 stock<br />v8(na): 12.18@113, 392rwhp<br />Moderator on <a href=\"http://www.mtfba.org\" target=\"_blank\">www.mtfba.org</a> and <a href=\"http://www.frrax.com\" target=\"_blank\">www.frrax.com</a> (Road Race & Autocross)<br /><a href=\"http://community.webshots.com/user/johnduncan10\" target=\"_blank\">Car pics</a>, <a href=\"http://www.trscca.com\" target=\"_blank\">TN Region SCCA</a>

I know relatively nothing about nitrous :D so take my advice for what its worth... nothing...
but i have heard that our motors can usually handle up to a 75 shot safely. anything over that is considered pushing it. If it were my motor, I would stick to a wimpy 50 shot, which is probably what ill eventually do.

If you have no saftey devices.. don't run higher than a 50 shot. If you have saftey devices then a 100 shot properly tuned should be perfectly fine as long as you don't leave it on and try to use it for daily driving and merging with traffic constantly.00\' firebird v6 5spd<br />201rwhp ---- 230 rwtq<br />\"Everyday I grow stronger...and further from you.\"<br />WARNING: Do not take any of my comments seriously unless they are technical in nature and then only at your own risk

As long as you have good/aftermarket ignition and fuel set-ups, then you can go pretty damn high. By monitoring those two things alone, you can use a 150 shot without any problems,,even higher. The higher the shot, the more it will hurt your internals in the engine. You can continually spray a 50 shot for more than a year, and not have problems. The more abuse you put on the motor, the more chances you have of messing something up.94 Camaro 3.4 A4 <br />T-Tops<br />In the process of an LS1 swap.

Do you suppose that's because most of the strips around the country are closed for the season?
I have an 85 dry shot. I have run it way to rich way to lean, and everything in between. I have bounced off the rev limiter, missed shifts etc...
I have sprayed a couple times way below n20 operating rpm range. [img]graemlins/dunce.gif[/img]
I contend that the 3800 II is absolutely invincible. Maybe magical engine gnomes sneak into my garage at night and fix things. I dunno.

That probably has a lot to do with it.
I know I'm still going to be modding mine during the off-season, and see what I can get out of it first thing when spring gets here and the air is still cool. [img]smile.gif[/img]
First thing is to get my powerdyne on there and tuned with no nitrous, then start adding nitrous back onto it. Maybe convert to a wet kit too, I'll have to think about that some more...
And one of these days I need to take my SSM heads out of the cabinet and put them on the engine. I think they'll actually end up on a spare engine, with a decent blower/nitrous cam install at the same time, then just swap the whole spare engine into the car with all the goodies already on it.\'98 A4 Camaro v6->v8 conversion, and STS kit next<br />v6: 13.6 Powerdyne, 13.2 150 shot, 13.8 120 shot, 14.3 85 shot, 15.7 stock<br />v8(na): 12.18@113, 392rwhp<br />Moderator on <a href=\"http://www.mtfba.org\" target=\"_blank\">www.mtfba.org</a> and <a href=\"http://www.frrax.com\" target=\"_blank\">www.frrax.com</a> (Road Race & Autocross)<br /><a href=\"http://community.webshots.com/user/johnduncan10\" target=\"_blank\">Car pics</a>, <a href=\"http://www.trscca.com\" target=\"_blank\">TN Region SCCA</a>

Knock on wood!!
I am sprayin a 90 Nitrous and 75 fuel.. My car is running way rich with my Walbro 255.. Our cars will take a 125 wet shot easily.. Our internals are good and strong for stock internals.. My roomate has a 4.6 GT and he was sprayin a 125 on it for a year straight.. Our 3.8 internals are alot better then his stock internals..Jeff ..

I would agree with most.
I'd say a 100 wet shot with appropriate safety gear and proper fuel system upgrades should be safe and reliable.
On another note, has anyone utilized a direct-port setup? If so, what were the difficulties upon installation?
Any and all information and pictures would be greatly appreciated.1995 3.8L Mustang<br /><a href=\"http://www.bmnracetech.com\" target=\"_blank\">http://www.bmnracetech.com<br /></a>
