On a stock engine you will have the best performance with the long tube runners or the superram.

Pretty much the same thing. One just accepts a standard small block distributor out of the box.

The difference between the two is minimal, they are going to produce the same power numbers and curves.

StealthRam only change,,, ran 1.8x 60s, near identical ET, 2 more mph but I had to shift at 6400/6200 rpm.

I liked the FIRST better for that particular combination - much more fun to play around with,,, and I consider myself an old school single plane carb kinda guy.

I myself have been in miniram's with 383, and there is no loss of torque. I have been in cars with Superram's, Steathram's, TPI's, and Miniram's. I have always been impressed with the 3 inch runner design. After riding in a 383 and a 350 with a Superram, I made up my mind quickly that I would never want a Superram intake on my car so I sold mine.
Out of curiosity, how exactly did you come to the conclusion that the Super Ram was the problem and not something else like the cam, heads, ect....


Different strokes for different folks. The ease of installing a Miniram is also a huge bonus. I dont want to get into a pissing match. For me the Miniram is where it's at. I am building a big stroker motor. I am sure it will perform well, and I will have more torque (approx.460rwtq) then I know that to do with.
FWIW, if you stud the SR it goes on and off pretty easily, I can get the plenum off in 1/2 hour, and the runners in another 1/2 hour. The real bitch is the valve covers are in the way, and that only adds about 10 minutes.

A few years back I drove an LT4 which was stock. It went really well, and that was stock cubic inches with a short runner intake. A miniram will work on stock cubic inches from 350 and on......
Which has nothing to do with anything...

I knew I joined this forum for a reason! Thanks for the great responses to my question. If I'm weighing the good against the bad and knowing where I want my power (low to mid/high mid range), it looks like the Accel SuperRam Intake w/High Flow Runners are the right choice for me. It will give me a nice boost in power and torque as well as allow me to keep the EGR valve. Now, does anybody have an extra grand laying around that they could lend me? Thanks again everyone!

I would like some input to help me - not trying to hijack. Wouldn't a manual trans & headers/catback alleviate some of the low-end loss of the miniram on a stock head/cam car?

And in regard to the true SR setup - mainly plenum/runners, can the install be done w/o taking any rockers off? Valve covers understandable, but I don't want the hassle of adjustment. Can anyone comment? I've searched here and elsewhere, and have seen conflicting experiences.

It can be done, but it's trickey.

I had to take off 2 rockers.

This would actually be a good time to replace the rockers with a set of 1.6 RR's. I think thats what I'll do when I tackle this project.

The last time I had the Miniram on a stockish but cammed motor, I have done better 1/8th mile ETs than 6 speed LS1 Camaros who told me they had "bolt ons." Well they couldn't get off the line quick enough. If I still had this set up, I would still love trying to experiment with it. The Miniram on a stock motor is essentially a stock LT1. I'm sure the dyno numbers are similar. I just can't see how a stock motor with a Miniram and good tune couldn't attain at least 300 crank hp, or 260ish rwhp.

Uhhhh, it can't be both! The right cam can add a lot to low-end performance.

In what car, at what weight? What gears? Too vague....

As long as you change the (L98) exhaust/headers, improve head flow, and increase cam lift by .5", I agree. In reality, the mini looses about 10% torque under 4k rpms (vs long-tube runners). Obviously, it gains it back above that -- plus more. The end result can be a faster car -- as long as you keep the rpms up HIGH. Do most people do that on the street?

I agree, but most people don't look at WHERE the power band exists. Are we talking street application or racing? If the application was racing, heads, cam and other items would be included as part of the mods -- and I wouldn't be responding to your post.


To the OP:
The superram may or may not be available. I had one person email me saying it could still be special ordered thru Jegs (etc...) I've never seen a post where someone actually got one that way. You probably have to find one used on eBay. And, used ones might be the ones people had more trouble with....

I think there are two different super-rams. Accel offers one that the long tube runners attach to and then TPiS offers one that looks like a bigger version of the TPiS mini-ram. Are we all talking about the same thing?

If you look at the link posted (above your post), you'll see that jmlr98 is talking about the short-runnered, big-azz-plenumed version that's supposed to be discontinued...

And, no one calls the Large-tube runners a superram, but they do call the base the superram base.

The LT4 has alot to do with everything infact. It shows that a very "mild" 350 (300rwhp) with a short runner intake is a performer. Any addition of cubes will benefit the miniram.

Superram is a pain in the butt to work with. You need to stud it? Which is modifying it. Like I said. I like the Miniram. I have been in a few LTx, and a few early C4's with the miniram installed, and I loved the way it pulled with the flat torque curve.

I am not going to argue with you. I know you installed the Superram which is great. I hope it performs for you, and you like it. I on the other hand have had good experiences with the Miniram, and it suits my built much better then the Superram.

I called them just last week & the guy at the order desk called Accel. He said Accel told him the Plenum/Runner kit was discontinued for an "undetermined length of time" because of "technical problems".

I think you are talking about the Accel base used with or without the large long tube runners. That is not the true SuperRam most are talking about.
It won't produce the improvement in performance that the Miniram will.

When designed by a team of GM engineers, yes.
Superram is a pain in the butt to work with. You need to stud it? Which is modifying it. Like I said. I like the Miniram. I have been in a few LTx, and a few early C4's with the miniram installed, and I loved the way it pulled with the flat torque curve.
It's really not that bad, but that's besides the point...to my question, how to you attribute all of the performance to the intake? Teach me man, teach me.....

I am not going to argue with you. I know you installed the Superram which is great. I hope it performs for you, and you like it. I on the other hand have had good experiences with the Miniram, and it suits my built much better then the Superram.
I don't want to argue. What I have or don't have is irrelevent. I'm just wondering if your conclusions are based on something more than taking a few rides in cars, which you have no idea of the totality of the build.

I thought you can teach me something, guess not. Note GREGGPENN's posts, they are always informative and chock full of information. I learn from his posts. He has something to teach.
