Re: X-ram??? (TyrelsVette)
you need to change your ie settings to accept all cookies..then it'll work
Heres some pictures of the offy.
Original manifold on the offy, notice how tiny the original ports are, it probably the worst design ive ever seen.
Its a clone of the crossram offered on 69 z28's with high winding 302 engines. The ports are huge! The only problems are the manifold wont clear the wiper motor. It has to go, or you need to modify a smaller one to work. Jonas is using an 85 blazer with a few mod's i believe. The other problem is you need to have a custom top plate made to mount the tbi's too. Oh and you need to loose the airpump to clear the water neck.
Or you could always use the single 4 barrel lid and run a carb or 454 tbi with an adapter plate (holley makes them)
Any way you look at it the offy isnt bolt on and will take some creative work. I think 3 people here have it, working rather well.

Re: X-ram??? (TyrelsVette)
its around 250 dollars less than the xram, yes its better than the xram, its a crossram, so it build large torque numbers, the xram isnt a crossram its a single plane manifold so it wont build the midrange torque numbers a stock manifold or an offy will build. heres some flow numbers
Stock Manifold
176 CFM @ 28" (with lid AND swirl plates installed.)
Second, the corrected Offy numbers:
304 CFM @ 28" (yikes!)
And the X-Ram........
252 CFM @ 28" (not too bad.)
Also
"mildly" ported stock intake flowed 199 CFM @ 28"
Stock TPI 200cfm
ACCEL Hi-Flow intake manifold
with 3/8 inch radiused inlet.........251.51 cfm
Extrude-Honed ACCEL Hi-Flow intake manifold
with 3/8 inch radiused inlet.........275.83 cfm
So as you can see you can match a tpi with a ported xfire, which means 300hp is entirely possible. And if you do a really good job with an offy you could out run a super ram car.

Re: X-ram??? (nsimmons)
wow, thanks dude, where can i get this magical device? and with parts and installing how much will it reasonably cost? like under a grand? i would love 300, my last car was a LT1 so i need more jam than the crossfire offers! links would be swell! :cool:

Re: X-ram??? (TyrelsVette)
you get get it from paw http://www.pawinc.com/
make sure you know what your getting into, you'll need a good engine under this thing, larger throttle bodies, larger injectors, you'll have to reprogram the ecm. You'll loose your wiper motor, you'll have to fabricate, or have made a top plate.
The simpler easier method is to install some decent heads, nice cam xram larger tbis, a little programming, easy 300hp
I can show you some various buildups that are simple and easy enough to copy for 270-300+hp
read this, and ignore everyone who tells you it cant be done, they've either never done it or done it wrong.
