I have a k20a2 in a eg and was planning on going with a shot of nitrous. I know the basics but what setup would be best for the k20?What size of a shot ? and what should I upgrade i.e.....fuel pump, injectors? I am already running and aeromotive reg. and proflo gauge. I am running kpro as well.

 

[joestypes]

I ran a 100 shot wet w/ a 255 lhp pump and stock injectors on my K20A. Just take back ign a bit. I think with decent tuning you can pull a 150 shot no problem on a stock motor.

 

[sloboy_hatch]

Yea thats what I was thinking a 125 to 150 shot.

 

[DWCHKYPMP20]

150? that would be nice....... hookups imprt tek here in so cal did a k20a (r) on an 80 shot and it did 315whp, no k pro!

and then they blew up the motor...

cause still yet to be determined...

they were making 300WHP+ I think...

that was my motor. it was on an 80 shot rich off the scale with no problems.

the reason it blew up was because i turned the bottle warmer on,ran several passes on the motor then hit the button on the dyno forgetting to check the bottle pressure and the motor let loose. this was just a costly mistake on my part. an 80 shot didnt blow it up....1900 psi in the bottle did.

 

[fasterthenU]

so beacuse of the high psi you were runing more nos than regular, i dont think that is how it works..

jesus christ, 1900psi. 850-950 is optimal bro.

The reason why is that the tank was to hot and it was around 1600+ or so

 

[c_buz]

1900 psi :wow: :wow: Aren't those bottles rated at 1800?? I was talking to a race car builder the other day (he has been around for a while) and told me that people at the track even torch the damn things to get the pressure way up, and this is pro mods by the way not some mickey mouse kid with a 20 shot. He said that he has known people that have blown bottles by doing this.

 

[dohcturtle]

it was an accident. we usually run it at 1000. it was just left on for a long time while messing around with K-pro for the first time.

I think thats were things went wrong..... (while messing around with k-pro for the first time)

theyv blew it up because the bottle pressure was to high

 

[civictyper]

ok so on a stock k20a type S... on a kpro... lets say i have a wet kit, off the intake blah blah blah.... i can run a 100 shot wet safe???? with 11.0 compression and on 94 octane????? i was thinking 60 shot max, thats what i did on my jdm b18c type R motor with the same compression, u guys are saying 100 shot is fine??

 

[RC000E]

That doesn't make sense because the bottles have a pressure relief valve which generally pops at 1300+

go with a nos direct 80 shot and u could tune it with kpro

old nitrous rule of thumb: You can safely spray half your hp as long as you retard the ign timing a few degrees and run 1 step colder plugs. This has never failed me to this day. I have had NOS on almost all of my car in the past 8yrs with shots ranging from a 65 shot up to a 125 shot, all wet kits

 

[K2e2vin]

theres a chart on Holley/NOS's website that has a chart of how much ignition and how much colder plugs to use at different amounts of shots.

edit: here's the link(its PDF format): http://www.holley.com/data/TechService/Technical/Tuning Tech Info.pdf

chart is at the bottom of the article.

 

[herney]

just go direct port 100 shot k-pro plugs race fuel and a good tuner, i have seen it done and nothing go wrong.
