Just added a 50 shot to my 95 civic with a supercharged b18c1. The car is still untuned since the motor build and sc port job. Wanting some input on what you guys think my car will put down on the dyno. Its got a built bottom end, stock compression, 12lbs pulley, intake, full exhaust, 440cc injectors....thats the basics. Tuning with Hondata s200. Im taking it to the tuner this saturday, Ill post up how close your educated guesses were!

 

300-325

edit: closer to 400

 

300-350 i bet

 

not if its a dry shot those 440cc will be way to small. but i suppose 300 with the spray way to hard to tell though and those injectors are really looking like a weak point in your build whats your fuel pressure is it stock? I doubt those will flow enough fuel without being over their duty cycle

 

I believe the fuel pressure is stock...not real sure. What size injectors should I step up to? I don't plan on making anymore hp out of this set-up, so the next step up is all I should need.

 

Well depends how much air that supercharger is really pulling in and how much horsepower you want but i did a quick basemap on crome and it looks like 525cc at least maybe a bit higher, i would do even higher because superchargers make alot of heat but im sure your tuner would recommend the correct size check with him, I mean if you only want about 250-280whp, 440cc should do just fine again it depends on if it is a dry or wet shot because a wet shot wont affect the injectors much and how much power your looking at.

 

it is a wet shot. But I will talk to my tuner about it. Tomorrow's the big day! lol

 

how do you explain that?

 

because it shoots the extra fuel in with the spray whereas a dry shot depends still on the regular fuel system, Good luck man hope it makes some good power didnt mean to scare you about the injectors i was just thinking if you wanted more power later on down the road bigger injectors will be a priority.

 

Its cool man, just lookin out. My tune day was called off, looks like I'm going to have to wait 2 more weeks! Thats when I was going to take pics of the car but I'll prolly end up doing it today.
