The dry hit thru the MAF has kept my stupid *** outta trouble many times...

 

Most of the fbodys and vetts i see at the track use dry with no problem.. That's what im going to use..

 

Parish has hit his with a huge dry shot! But he does have a megasquirt to control all the fuel.

 

 

Ok guys here is a great example. My nitrous noid was acting up and spraying, not spraying then froze up today at the track. Well, I am happy to report that no issues arose except the pride issue causing me not to be able to back up my smack. Now if this was a continuse issue with a wet hit before diagnosing problem, possibely this would have happened;
, slight chance yes, but still a chance.

I have been spraying mine with a 175 dry shot no problems i have it tuned to run fatter on the spray, but i do have bigger injectors and hptuner so i can test and tune, but this weekend i will be 2 staging it first stage dry then 2nd stage wet think im gonna go 100 then come in with a 150 wet and i will be putting in a bigger pump

OK, time for the totally ignorant outside observer to chime in.

Robert, I think you hit the nail on the head on the dry/wet controversy. GM trucks have a MAF, so a properly placed N2O nozzle can use the MAF to its advantage to provide a tunable, safe system. Many other vehicles (e.g. Dodge hemi, Honda) use a speed/density system with no MAF, and so this technique cannot be used. For them a dry shot is probably a lot trickier to do, and a wet might be safer. Same goes with the old-fashioned carburetor.

 

He also toasted a motor with a sticking fuel solenoid. If no one remembers that, maybe that could be searched. I did a home built dry shot (easy as crap) on mine and it knocked a solid 1.2 seconds of my E.T. on what was supposed to be a 100 shot, according to those in the know. I wasn't logging at the time, so I'm not sure exactly how "safe" it was, but I did run SEVERAL bottles through it with that "tune up". Just be careful on where you place the nozzle in accordance with the MAF, as I froze mine up being too close. If I was to do it all over, I would prob. relocate the MAF further up the intake tract and stick with the DRY shot. On a stock motor, I wouldn't want to go too big anyway, and feel confident that the stock injectors and MAF can handle the baby shots that I use. SPEEDY02, have you hooked the kit up yet or what??

Yep, some have moved the MAf with great success, another tuning tool, maf placement.
