Default TBI and Nitrous???

Firstly, i have been a proud owner and member on this board for about 12 months, but unfortunatley i lost all my information... pasword.... even my own e-mail address.... dumb ***!

anyway, i have recently purchased a X-RAM manifold to replace the standard on my 84mod. also have a cam to slip in while im at it, and some other stuff...... now, i would like to put a 100 shot of nitrous whilst i am doing these other mods.

Now my real question is, what/where and how? has anyone set up a wet kit on a TBI with an X-RAM manifold, i was thinking it may be possible to use a 4 BBL carb plate between the throttle body plate and the manifold that this X-RAM? would this be at all possible? or should i look at using a single fogger tapped into the side of the manifold wall???

I have no prior experience with nitrous, only theretical knowledge, but that only gets you so far!!! any help would be appreciated!

Cheers Boys!

phwew tough question... I would try a fogger nozzle approach for simplicity sake... easy to rejet and easy tp plumb. it should actually work better on your crossfire car then the later model tuned ports due to the manifold being designed to accomodate the flow of fuel and air from the throttle inlet opening.

so yeah do a fogger nozzle right infront of the throttle opening in the filter track like a normal efi system would get it. you should be just fine!!!

good luck and enjoy!

If you want a Nitrous system already set-up for a crossfire check out MB6970 at the crossfire injection vault. He had made his own kit from NOS brand parts and it was used on his X-ram. He ran mid 12's with stock displancement orginal long block motor. It ran very well,he just wants to sell the entire kit. Go on that web site and,if you don't,you passing up on a custom kit just for what your looking for.

if i was to use a single fogger tapped into the side of the manifold would i have a dispersion problem? being so close to the combustion chambers and on one single side of the manifold???? I thought i may be able to tap it in on the right hand side if the carb type manifold?

OPPS,didnt' realize you wanted a wet system,his is a dry system from uptop. Nobody that I know has used a wet system yet on a X-RAM,but would be easy. Holley makes a 1/4" spacer for what you want.

X-ram has been proven by a few people that their is fuel puddling problems and fuel distribution problems. Certain cylinders go lean and some go real rich. The design has its flaws and I owned one and ran one for some time. I got more hp/tq out of the ported stock intake and verified it at the track. Not much difference but a tenth or two is a good gain to none. I gained about 2.5 tenths from the X-ram and .5 from the ported stocker.

But,again,the guy who made his nitrous work with his X-ram made it work well and it ran great. Im not trying to steer you away from the X-ram or a Wet system by telling you about his dry set-up. Im just letting you know some options and personal experience.

thanks for the help so far. can i tap a fogger in the side of the manifold itself under the top plate, will i need two foggers (one per side) or can i get away with one on one side. i would like to use a wet system for simplicity sake.....

The bitch part about the X-ram is the base intake(weiand Xcellerator) is milled some to gain extra hood clearance for our C4's. Theirs no room to tap into the intake itself but just mabye use a 1/4 aluminum spacer for carbs.

Hope that makes sense.

I am completely ignorant about the X fire, but is there a reason you can't put the nozzle somewhere between the air filter and the throttle body blades?

I don't think so,I used a 3/8" lid spacer for the stock intakes plenum and the air cleaner almost touched the hood but didn't. Very close but you do have 1/4" safty blanket for sure. If 3/8" didn't touch then 1/4" should be fine.

Neat, there is a forum member who made his own kit and it ran simular to that. The nozzles were inside the aircleaner assembly and it was nicely hidden! It was a dry system but it worked very well for years on a stock 20+ year old long block.

excellent, that will be very easy to install then. i dont want to go diving into complicated wiring etc for the dry system. i would rather have a simple easily removed system. cheers..

A friend of mine had the same idea he said point the end of each nozzle into the TB but the only thing is the overheating factor. so thats why I got a 160* powerstat and headers he said this would help slightly but that I should still be careful.
