b16a supercharger(compression?)

i have a b16a stock compression is 10.2 what compression should i use with the jr supercharger. i also have 55 zex, skunk2 head, and all the other stuff you could put on the engine if that matters. i want to upgrade the pistons and rods for future abuse and hp so what compression should i choose......

:huh:

you can run the stock comp ratio of 10.2 with the jrsc. make sure you dont run a dry nos with your jrsc. you need wet nos. you can run the stock comp ratio with all the other parts too

why no dry jr said it was fine as long as i put the line in after the air was compressed (tap the plenum chamber of the manifold, directly across from the intake ports)

run what ya got it should run fine and the stock compression ratio should work fine if it didnt im sure jackson would try to sell you some lower compression pistons or something money grubbing sob lol sorry

if you tap into the intake mani then your looking at a fogger system

i was about to buy a dry nos system, i didn't know that it wouldnt be smart with my supercharger, can someone tell me why and what i can do about it?

well toyosupr said that jackson racing said he could run nos as long as its a fogger system or direct port. after the air is compressed

so if you wanna run nos on your car with a jrsc, run either a fogger system or direct port.

to be safer why dont you call jackson racing and ask them, also call teh nos company and ask them too.

how does the fogger system hookup compare to the dry...

In a wet system, nitrous oxide and fuel mixed are at and then delivered through a "fogger" which is directly threaded into the throttle body (or intake tube). Steel braided lines are attached to the N2O bottle and the fuel system and are opened and closed via switching solenoids.

Inside of the nozzle are "jets" which determine the amount of N2O sprayed into the engine. This is what actually determines the amount of "shot" that any given kit will produce. The larger the jet, the higher the horsepower output and vice versa.

The dry manifold system is similar to the wet system, however the fuel and nitrous oxide are NOT mixed at the fogger. The N2O is injected into dry air (without fuel) upstream in the manifold and it is then mixed with fuel at the injectors. Since this type of system has no real means of adding the additional fuel that is required to burn the extra oxygen, it should only be used for less than 70 hp shots with factory injectors.

Direct-port systems are by far the best for reliability and power, but are also the most expensive and most difficult to install. This kit is basically a "wet kit", but each cylinder getting its own fuel/nitrous nozzle. The fogger injects the nitrous and fuel directly into that cylinder's intake port. The installation of this type of kit requires that the intake manifold be removed from the engine. These kits offer the highest horsepower shots due to their ideal N2O/fuel mixture at each cylinder. This would be the "must have" kit for the serious strip racer.


so a fogger is nos mixed with fuel, dry is just nos, direct port is nos mixed with fuel but each cylinder gets its own nozzle.

from what i understand about the jrsc. right after the blower unit itself, it divides into each intake runner for each cylinder. so the only option i see when running nos with a jrsc is to tap into each of the 4 intake runners and run nos in each of the intakes, which would then make it a direct port. because after the blower unit, its compressed air, and not before it. so only after the blower unit its compressed air and it goes right into each intake runner, so the only option i see is to tap into each intake runner which would make it direct port.

sorry i did say fogger before but after thinking about it, i was wrong, you should use a direct port with any type of forced induction

i strongly recommend you call the nos company and ask them about what type of nos systme you should run with a jrsc. they will give you the absolutly correct answer.
