i'd just like to get an idea of the people that have the superram, and some feedback about it. i have been looking for an intake, at first i was looking to stay with the long tube runners, and just get the TPIS base and runner kit. however since that will be about 1,000 dollars, i've been looking at other intakes, such as the Accel Superram, the Holley Stealth Ram, and the TPIS Miniram. i dont like the fact that you need different fuel rails for the miniram and the stealth ram, and that both of them dont use the EGR. this is why i'm leaning towards the superram.

please let me know, is the superram compatible with the stock TPI base? what is the best base i could get for the accel super ram for the least amount of compatibility issues? please let me know anything i havent stated about the superram. money is no object, i would like to keep my EGR though. thanks

 

I switched from stock tpi to super-ram 2 yrs ago. I use the accel base manifold and runners(Naturally when I did new comp cams xfi cam a month ago I had the base ported and opened up a little more). Its a huge improvement over stock tpi set-up, plus I got mine powder coated and hand polished the top plate and it looks cool as hell and I still have my egr!Go Accell super-ram all the way!!!!

 

The SR will work with the stock TPI base, but to get the full benefit of it you need a base with larger runners. TPIS, Edelbrock, etc. all make them, but I'd suggest going eith the Lingenfelter/Accel base myself. night as well keep it all the same brand so there can't be any compatibility questions. The SR is also the only one that's emissions legal though I noticed that is not a concern right n0w. Who knows what could happen in the future, everyone could be emissions testing before too long...

 

I've owned mine for about 10 yrs now and have been very happy with it.

But, it depends on what you want your car to do as a complete package (heads, cam, stroker, or possibly supercharger) such as street car, drag car. Although I like the SR, there are better choices depending on your application of the car based upon what you want it to do. For an all around street car, that only sees limited drag racing at the track, the SR is a great choice. Good mid range torque and enough top end power that you'll notice a big difference over LTR. The strong mid range TQ makes the car fun to drive on the street, especailly at the top end.

There are a lot of people on here who think this is a POS manifold. It is not, maybe a little over priced, but it is well designed. Take your time with installation, read the directions several times, read the threads on here about streamlining the install, learn from our mistakes and you'll have no problems. It was designed for performance, not ease of install and the first time you install it, expect a full afternoon of cursing and work. However, with the guidance above, you'll keep that problem to a minimum.

Keep in mind that you'll probably need a PROM update. And, while you have the manifold off, it would be a good time to do heads/cam if you can afford it. Then you could have the PROM burned for all of your changes at once and save a few dollars.

My old 350 TA ran 13.00 @ 106 on street tires with a SR, LPE 219 cam, AFR 190 heads and 9:1 CR. With slicks, mid 12s wouldn't have been a problem. This is a proven combination that many on this board have ran and it works well together.

Hope this helps, if you need any installation advice just ask or do a SEARCH on this subject. Good luck.

 

Good summary! The HSR/Mini-Ram/LT1-LT4 intake conversions are easier to install, but they are not emissions legal if that matters to you, plus you usually run into clearance problems only on the Firebird hoods (not on the Camaro as I understand it). Those other intakes will allow you to wind the engine to higher RPMS, but that only helps you if your motor internals are built to handle that and the cam and head combo you have is designed for over 6K RPMs. You also loose torque in the mid-range and lower end area with those other intakes. High RPM HP always costs you some manner of torque on the opposite end. Just a matter of physics, it's a trade-off you can't totally avoid.

My SR is still pulling good at 6K, but my cam tops out my HP around 5600RPM so I have no need to go much higher.

 

awsome, i cant say how much i appreciate all your help, i will probably definetly go with the super ram when i get my heads/cam completely figured out, right now the specs of my cam are exactly this:

holley lunati voodoo:
hydraulic flat tappet
.050 duration: 227in 233ex
Valve Lift: .489in .504ex
lobe seperation: 110in 110ex
1,800-6,200 RPM

is that lobe seperation too small for FI??? i already own this cam, however it can be returned, i havent used it at all and it is still boxed up. i've heard very good things about the lunati voodoo series, this is why i bought it.

 

To be more computer friendly, 112* LSA is recommended,,, My cam has an LSA of 114*, as recommnded by Comp Cams who custom ground the cam.

 

If any plans are to build an engine larger than a 406, I would stay away from the S/R, not for being a pain to work on, but for flow reasons. For 350s, 383s, 395s, you should be fine. Once you are in the 406+ territory, I would go with a single 4 barrel T/B conversion. If your heads are flowing in the 280-300 cfm range, through the intake port, the S/R, IIRC, flows about 220 cfm, as cast. With a full porting, you may pick up an additional 20, to 30, cfm. It will still fall short in flow. Not sure about the HSR, but alot of people are using M/Rs, on larger combinations, with great results. If you plan on putting it on your 355, I would say go for it. My S/R is coming off this winter, as it is now a 'bottleneck". Not real bad to work on, once you do it. The reason I posted, is in case you might want to increase your cubes down the road. The S/R is what I had, so I kept using it, until I perform a change this winter.

 

Im pretty sure the Superram flows 240 cfm as cast and 280 fully ported but I could be wrong. Im saying with a high flow base though. After that you would need some extremely good flowing heads. Not many 23 degree heads will even flow that. Stealth Ram will flow 300 cfm ported and can perform similar if not better that a Superram. Reason I say can is that your heads and cam will play a big part in the performance and driveability your after. So dont get sucked into the highest flowing intake thing that most of the racers will try and put forth here. I mean do you really need a 9 second car to get you around town that sucks your wallet dry because you have to go to the gas station everytime you want to go to one of your friends houses.

 

Some people on this board have ported out the SR. I've ported mine out so that a golf ball will drop thru the runners with no problem. I figured a golf ball would work well as a design tool to keep the passages close to same OD.
Also, port match the runners and grind a generous radius into the plenum where the runners meet the plenum.

 

one question, to mainly you guys porting this intake.... how much power are you guys looking to make??

 

My goal is 400 RWHp. Now I'm at 340 RWHp. Check my thread starter concerning my best ET ever.

Next I need to build my own larger MAF sensor. I'm a bit stubborn, I want to run 11s with a MAF sensor using the factory ECM with my own Eprom chip.
NA of course, all motor.
