How much N2O would i be safe spraying with 11.5 compression?

 

With good tuning you can do way more then that. Tunning is the key to a good motor.

 

yes tuning is the key

as I ran a 50 shot with 11:5:1 compression and expanded two pistons

Forged too

Sucks to be me

 

truthfully i would run about a 25 shot seriously.

 

What type of gas were you running when you expanded your 2 pistons? And to the originator of this post, what octane will you be running when you spray? Hopefully not 91...

 

if you have big enough injectors, 310cc is good for about anything up to 100 shot. higher octane is a MUST. and if you tune it properly then you can actully go bigg like over 100 shot. but if you really dont want to worry about it just use like 40-55 shot with aftermarket injectors and 94+ oct AND tuneing and you'll be cool

 

you should be able to spray alot if you tune, like everyone says, remember pro-mods spray on like 15:1 comp. yes i know they are built to the max for this, but if you are going that high make sure it is done right, and not "this is just to get me by" mentality

 

im in the same shoes at 11-5-1 and im going to spray some were like 75-120 it going to the dyno on the 8th ive got my rc 310 and run 93 octan. tuning is the key this is true good luck with your's. ill let you know what mine did.

dude i would defenatly consider a higher oct.

 

for daily drive 93 or 95 would be fine right but when i spray what should i run 105 or higher

 

i dont know about you but i would only do it on 110-116 gas only if its not tuned just to be safe .

i have 11.8:1 and will be doing 50 and 70 wet with C16 track only.

 

i personally have run up to a 125 shot on 11:1 C/R on 93 pump gas w/o any problems. the internals were forged of course to withstand the abuse. as long as there is enough fuel and the ignition timing is brought back properly the engine should be fine with 11.5:1 C/R and up to a 100 shot (or more). if you can correctly tune your motor N/A first with Hondata and then use a DP N2O system with a Digital 6+ or something similar (for the proper ignition retard while injecting), then it should work very well since the fuel will be provided via the fuel jets and mixed with the N2O for a proper mixture. and of course make sure you have a fuel pump that will flow enough to feed both the injectors and the fuel jets.

exactly....if you are going to run that much nitrous on that high of a compression....take it to a dyno first.

good to know someones done it

 

hey i have 12.5:1 can i run a 5o shot?on 100 octance fully built ls vtec

 

n2o loves compression, but tuning is very much the key. dont really want to go over a 75 shot on stock sleeves! (yes, i know people who have run over 75 shot on stock sleeves, its just not reliable!)

 

i gots dartons sleeves and tunnin very soon
