I am in the planning phase of a complete engine rebuild , im looking at adding LT headers and either a Miniram or Superram but i cant decide which one to use .
I know that with the Mini Ram i am looking at LT1'ish numbers with everything else stock. and headers/exhaust, but what about the Super Ram. Which will give me the most bang for my hard earned bucks?

Any one who is using either would be of great help

Thanks in advance!!!

Do a search!!!!
If the function is working you will find hours of reading dealing with the two intakes.
Bottom line - the complete engine including intake has to be a package. MR works on certain packages while SR does the same for specific engine packages.
You have to decide what you want from your engine before a real decision can be made.

Yes if the search works then you'll find more than you want to read.

Either is capable of great numbers, but the engine combination suited to each is a little different.

Plus I would not use the MR on an automatic.

i have a miniram on now. 91, 350, tpis longtubes, dart pro1 heads, 11.1 6speed 3.33gears. im still in process of getting all the bugs out and doing a cam swap. going with a tpis zz-x cam 239/239 @.050 .595/.595 lift. it is a bit large for a street car but ill deal with it.

basiclly to get make it worth installing either the miniram or superram, lt headers, heads and cam are almost a necessity.

and your type of driving and personal preference will dictate your choice..

i will let you know how i like the minram with this new cam after i get it tuned right.

This is perfect advice (if the search does indeed function )

The only other things I might add is a MR is a HP (RPM) oriented intake, while the SR is a torque (lower RPM) intake. One other factor to be considered is the SR carries an EO numbr and is therefore smog compliant

Ask yourself:

1. Do you have a forged rotating assembly?
2. At what RPM do you want to shift at? shifting at 5800-6000rpm on the street takes up the road pretty quick.
3. Do you want a major SOP feel at low end or upper end?
4. The MR likes gears, at least 3.53 but more like a 3.73 or even higher

Just a few days ago I posted several links to sites where actual back to back dyno comparisions were posted of the MR, SR, HSR and even a siamesed system.

As others have suggested, do a Search and you should find them. I believe the title of the post is "Flow Numbers, Flow Numbers, Flow . . ."

Oh no, not this again. We should just have this put on a sticky at the top so we can refer to it by number....LOL.

I have used both intakes on street cars so you might call me "experienced" pertaining to this topic. Here is my advice...

First of all, if you have a 350 or smaller displacement engine and don't feel like revving the daylights out of your engine (more than 6000rpm), I suggest you stay away from the miniram. If you have a 383 or larger displacement engine and you want your powerband to be maximized in the mid- to upper-RPM ranges, then the miniram is for you.

I tried the Miniram II on a mild 355 SBC, TFS Twisted Wedge G1 heads, headers, LT4 HOT-CAM (even tried a slightly smaller cam per TPIS's advice), etc, auto trans w/3000 stall, and 3.73 gears in my 3500lb 86 Monte Carlo. The car could only muster a best of 13.6et @ 105mph using the miniram intake. With the slightly smaller cam (per TPIS advice), the car went 2 tenths and 2mph slower in the 1/4. Put my ported TPI setup back on and the car ran a 13.45 @ 103mph, plus part-throttle, around town driving greatly improved. The miniram intake didn't allow the engine to make any torque below about 3500 rpm. What's worse is the engine didn't even feel like it really started to wake up until I reached about 4500rpm and then it wanted to keep going well past what I felt was a "safe" red-line of 6400rpm using the factory hydraulic roller lifter setup. I guess if I had a manual trans, the miniram would have felt more "at home" than it did with the auto.

To make a long story short the Monte met with an untimely demise and I "upgraded" to an 87 Trans Am GTA. (probably picked up a little weight but lost wind resistance). Around that same time I traded the miniram in for a SuperRam with ported Edelbrock base. Right away the first thing I noticed was I got most of my low/mid range torque back. If I had to rate the powerband on a scale of 1-10, 1 being a stock TPI with massive low end TQ, and 10 being the miniram with maximum top RPM power, the Superram would come in at about a 6. While it doesn't have the ultra-low RPM grunt of the stock TPI, it does have a very broad power band more suited for what I consider to be a daily driven street car. Keep in mind the miniram absolutely sucked trying to drive around in traffic, might as well have had a tired 305 carburated. The Superram seemed to work quite well on my mild 355 so I decided to dyno the engine.

Link to the dyno chart (Superram): http://dtcc.cz28.com/gta/dyno.htm

378hp and 440tq SAE corrected power readings at the crank. Notice how relatively flat the torque curve is on the dyno chart. Obviously the Miniram never came close to producing this level of torque nor could it produce the same torque curve. After I dynoed the engine, I went to a one-step bigger cam (Comp Xtreme 224/230) and ran this combo at the track with a best of 13.1et @ 109mph.

Basically what it boils down to is: if you have a car that weighs more than 3300lbs and has a 350ci or smaller engine and will be seeing primarily street duty, I suggest you go with the Superram, you won't be disappointed.

Now don't get me wrong, the Miniram intake works, but you better have a good rev kit installed and make sure your engine can handle those higher revs or you won't be getting the most out of the miniram's short runner configuration.
