i'm not a big fan of nitrous but i was told i can run a 100 shot on my stock motor in my 05 evo vlll i have boost controller set at 22 hks dp hks hi power exhaust hks filtes is it true a 100 shot will be ok i wanna call bull**** on this guy

 

hks filter sorry guys

 

I'm gonna have to go out on a limb on this one and call his bluff... 100 shot of nitrous is quite brutal if not correctly set up. The MOST I would PERSONALLY run is probably a 75 shot and that would be pushing MY envelope of worry...

Your mileage may vary... (YMMV)

well i now a little about nitrous i'm not looking to go direct port just a dry if i even do a shot BUT and this is a big BUT would i be able to handle a 100 shot dry?

 

i'm at like 65k

 

A dry shot??

Especially 100 shot dry is asking for some SERIOUS engine ownage...

Good luck...

a 100 dry shot is like a 75 or 80 shot actual so i don't really see that as a problem if you told me to go with a 75 shot before i think you don't really know what your talking about

 

75 is about the limit for an engine with stock internals. Seen one friend run 75 for over a year no problems. Got greedy went to 100 and BOOM.

 

Now I'm about to own you so be prepared...

when I suggested my shots, I assumed you knew better to use a wet shot... A wet shot means nitrous AND fuel at the same time.

A dry shot is merely injecting nitrous into a motor WITHOUT compensating any fuel for the added increase.

Shooting dry nitrous is okay with smaller shots. Shooting it at 100 shot is merely retarded.

I see you have a VERY low post and posted newbish posts asking about using 272 cams with stock drivetrain. I would highly suggest you make use of the search function before posting such frivolous crap.

I'll back off because you've ultimately pissed me off...

Evogrl-

There you go... Someone who has first hand experience with your great idea...


Evotech... I applaud you...

 

why would i run a wet shot when the intake plenum isn't designed to have fuel injected through it? if it puddles up BOOOOOM nitrous fart there goes my manifole and who knows what else you can say it's crap all you want i don't know that's why i'm asking *******

 

manifold miss spelled

 

like i said a 100 dry shot is is only max an 80 shot you never get the full shot out of a wet or dry as like a direct port

 

I'm assuming the stars in your post was the word a-hole but I'll remain neutral... Time for a little lecture and schooling...

Combustion Cycle is made of Air/Fuel and Spark. You make more power by adding to all three, but all three have to be kept in balance. If you add Air you have to add fuel. Adding Nitrous is adding Air, so you have to add Fuel as well.

Wet-Kits: Wet-Nitrous either uses it's own supply of gas or taps a fuel line and injects gasoline via an extra injector solenoid. Wet kits allow for precise fuel metering, but can strain the fuel system if they scavenge too much. The is defeated by either upping to a 255 pump and/or upping the injectors sizes.

Dry-Kits: Dry kits rely on "existing" fuel sources to provide the extra gas. Extra gas is accomplished through either increasing the fuel pressure, or having the computer add more fuel. 10 years ago Dry kits normally meant either adding fuel pressure by injecting nitrous into the fuel-pressure regulate vacuum control line or adding it via a computer modification to the ECM. Today "dry kits" typically blow through a Mass Air Flow Meter and rely on it to detect the extra oxygen and provide more gas. Advantages: Easy to install. Disadvantages, you're asking the fuel system to do something it wasn't designed to do and that can cause problems.

Also, doesn't wet kits have a better chance pooling up in the intake and exploding? No. You're referring to a nitrous backfire, which is related to poorly designed and way over jetted wet kit. Nitrous doesn't explode, nitrous aides explosions.

These are boost cars. Extremely sensative to afr. Running nitrous dry at any shot with its high oxygen content is going to lean out the afr. I would imagine enough to cause extreme heat and detonation.

A wet kit with todays nozzles atomize very well or suspend the fuel in the air very well. Which will leave no worries for puddling. IMO

PM a Dude on here named Drag. He has played with some nitrous shots over a 100 on his basically stock 05. He has cut out, mbc, and ecuflash stuff. As well he seen gains from 12.7 to 11.9 on a 50 shot alone.

This guy is a well respected engine builder. He is currently racing a Insight that has seen mid 10's. I am thinking it has seen the track only a handful of times for it was completed late summer of this year.

So to be safe run a 50 shot wet. Get some good gains and have decent margin for failure. harrispeedworks dot com has a kit for 340. Universal EFI. He will send you the 50 shot jets. I have been buying from Matt at Harris for a few years now. Best prices and best advice around.

Good luck. I am a nitrous junky but chose methanol injection as my next power adder. I figured we got boost while limp it with nitrous. I want my power every time I drive. So opted to stage out a turbo upgrade. Meth kit, then a FP green. Should yield a quick and fun Evo. That will have good low end spool and TQ.

Best of luck. Please do not spray dry with out a way raise fuel pressure in turn adding more fuel. You need the fuel to be there. The dry system is only referencing the spray entering the motor. Fuel is add via raised FP.
