Safe n20 levels

[b_diddy]

ok, i know your not supposed to spray on a stock 7 bolt block. theyre rods are to thin to handle it, or something along those lines. But, would it be ok to run a 25 shot in just 3rd gear? would this be to much?

what all would need to be done to safely run it on a 7 bolt, and not swap to a 6 bolt?

Why run nitrous anyway? It's too much of a hassel on a turbocharged car unless you're going all out anyway and have everything to back it up. If it's your only car (aka daily driver) I would strongly recommend against nitrous. Try checking out water injection for something safer and more reliable.

ok, i posted this along time ago, but am reasking the question. i am considering doing a 25 or 30 shot, and wanted to know whether or not its safe on a stock bottom end.

also, if this is safe, what setup would be appropriate for this?

i agree, brock.... keep it simple man, there are much better alternatives for daily driven dsm's water is good and im looking at a alchool kit for my self..... ive never ran n2o but i dont intend on doing ANY sort of shot unitll i have upgraded internals...

People used to think that a 20G was as big a turbo that you would ever need on a DSM. Take that as you will.

My brother Jason Martinez ran a 40-75 shot (can't remember which) on a stock 7-bolt bottom end on top of a 20g at 25 psi. The only bolstering the block got was ARP head studs. Nothing else.

Absolutely. The only reason you wouldnt is if you didnt know how to tune your car.

dude- wasnt there some guy at pueblo running atwo-stage kit on his 2g hitting mid-12s on a stock t2slo? I think so... and I believe it was a 125 shot two stage setup

As long as your car is running really good. If you have a misfire or a backfire you'll definately blow something to pieces.

As far as what to use. Go with a nitrous express single fogger for that small of a shot. Also if you don't have DSMlink invest in some window switches such as RPM, and TPS. With dsmlink you have all of that built in. Simply hook the relay up to the ecu and go.

The rule of thumb that some vendors use is :

"You should not exceed 20 hp/cyl on stock engine internals".

So on a 4 cylinder the stock engine limits you to around a 80 hp shot max. I have no direct experience with the dsm side but the WRX guys are seeing that is a valid guideline.

They routinely run a 35 shot with no problems with a known fragil transmission and a more detonation prone engine than the Mitsubishi engines. A 50 shot can be run if used carefully and above that they run a risk of drivetrain issues ( ie transmissions and clutchs). Mostly they must avoid the larger shots on launch to protect low and second gears, but can run a larger shot in 3 and 4, until they run out of clutch torque capacity. A hundred shot on a stock WRX transmission will nuke low gear on a single launch.

I would second Daves comment on the safety switches. You absolutely want to avoid any sort of fuel cut ( over boost or rev limit, low fuel pressure) while on nitrous. An rpm window switch, boost pressure switch and fuel pressure safety switch can solve that issue. The TPS and or clutch safety switch I also consider manditory.

taken from diamondstarmotorsport.com "We have been back on the bottle for 2004 and it makes us wonder why everyone is so afraid of using nitrous. It works SO well. It has taken our stock engine/stock turbo/2850lb 1g awd from mid 12's @ 109 to mid 11's @ 119.
Completely safe for stock 4G63 engines. A stock 4G63 can make about 400WHP with no problems. Nitrous is no more damaging to your engine than a 400whp capable turbo if it is tuned correctly, despite what Hollywood says. ;) "

They make it sound easy but unless you know how to "prep" your vehicle it will have drastic concequences.
