I was wondering if anyone has run nitours with either of these setups. I definitely want to run the NOS wet wet setup but I was wondering if I would be throwing money away on the intake.

thanks for any opinions,

Brian

 

Dont waste your money on the superram, get the miniram and you will be much happier. I think some guy from www.unlimited-racing.com has a direct port set-up on a miniram

 

Why would you say don't waste your money on a sr? I like the MR also, but i have yet to see a faster 350 iroc NA then mine with similar mods or even using AFR 190s vs my suposedly junk TFE heads that are box stock.

 

Typo-those are trick flow heads, TFW

 

dont mean to flame you, but everyone that i
PERSONALLY KNOW that has had a superram, has sold it in favor of a miniram. More horsepower and easier to service.

 

How bout TRAX?
12.5 @ 109mph?
are you running 12.5 super?

 

From what I understand, the superram does NOT respond well with nitrous over a 100 shot. Yoiu'll blow the top off of the superram if you run too much...It's something about the large plenum area, i dunno, but my engine builder said to stay away from NOS if you're gonna go superram.

 

Markolc,
Thats the kind of advice I was looking for. That whould definitely push me towards the miniram and its smaller plenum.

Thanks
Brian

 

I think trax and i should have a little competion. I ran a total of 4 passes with my knew setup in july 85 degree heat/humidity. I ran 12.9@110 The only suspenion mods are control arms and SFC I also have a 5 speed that i have yet to master in favor of the old 700r4. I also race at a ****ty slow track, thats right where a seasoned racer can only get his 98 VIPER GTS to go 114mph. I just put a loop on the car and i should get my alum shaft from james in the mail tommorow. I bet with a little practice i can go faster and much quiker with a torque arm and droped control arms etc. I will say that SR are a pain to install but i think they work great. I also have a ads crappy chip. I do believe trax has a custom chip torque arm etc, please correct me if I'am wrong. so yeagh i can run with the best of them NA.

 

I dunno there, Supa... first you say you and TRAX should race, claiming that you "can run with the best of them", but in the same phrase it sounds like you're already lining up your excuses. He runs a custom chip... you haven't mastered your 5 speed yet... he has a torque arm...

If you're already polishing off your excuses for the anticipated loss to Trax, how can you really say that you "can run with the best of them"?

Sniff... sniff.. anyone else smell the BS?

 

Excuse me i believe my car is already faster then his. I was merely stating the fact that my car has ALOT more potential. As for his quiker et well thats a function of traction while mph is the real measure of horsepower and isn't that what we all want. BS i don't think so. I would like to race trax and it would be a good race and I'am sure he has a lot more class then you and wouln't insult my intelligence. By the way what do you have?

 

I guess i will have to post some pics of my car and timeslips when i get a scanner and some time away from school and my newly found buisness . I just hate being called a liar.

 

Easy fellas. Testosterone levels are rising quickly!!


What converter do you have super?

 

I have a 5 speed in my car i put in last spring. I did run the car with the auto and 2:77 rear just before the 5 speed swap and she went 13.2@108 with the stock converter and tranny that was on the verge of scattering i think. This winter i plan on putting a six speed in but for know the 5 speed seems to be working, nock on wood.

 

DUHR! I feel like a damn idiot now. I seen you post it was a 5 speed



good luck

 

Geez ....

All this talk about me and I didn't even know about it

All I know is that if my car holds together I should be able to hit a 12.3x this saturday. We'll see. My car is definitely 'out of balance' right now ... so, I have my excuses too. My MiniRam setup needs more exhaust. My SLP 1-5/8" headers and the 2-1/4" Y-pipe just don't cut it. To that end I have Hooker Super Comp Long Tube 1-3/4" headers sitting on the floor If I run the 12.3 this weekend then 12.1's will easily be possible with the new exhaust. Swapping my converter to higher stall until will net me at least a tenth. Thus, 11.9's will then be very very very close. I'm still running the stock body panels so I could always add a fiberglass hood to reduce some of that frontend weight (we all know how darn heavy our hoods are!) and gain even more ET/MPH.

It doesn't do justice to compare a manual's MPH to an Automatic's MPH. The Autos (700R4s) will always run slower in the 1/4 in terms of MPH unless you can lockup throughout half of first and all of second and all of third. Alot of the MPH is lost in the slippage. However, what is lost in slippage is made up on gear shifting, the launch, and torque multiplication. The launch is most often (*not always*) better due to the use of a high stall converter and GOOD traction. There's no skill involved in launching an automatic ... if you have traction then you will 60ft really good :-)

Right now I am still running the stock bottom end of the motor from 1990 GM . Obviously, a rebuilt bottom end would help me out. But, I'm determined to see how far she'll take me. Believe it or not I am also still running the stock transmission (with a shift kit, a cooler, and an aux. filter). Most people refer to this as a miracle (on both accounts). We'll see how long they hold up. I take the stock bottom end and the stock tranny to 6500rpms ALL the time so its only a matter of time. I am sure that they are hurting me already and costing me precious ET and MPH.

Each intake has its benefits and each intake must be closely matched to the internals. I fully balanced setup for the MiniRam will master and outperform a fully balanced SuperRam setup IN THE 1/4 MILE. Note my use of 'FULLY BALANCED' This means a valvetrain and drivetrain setup that matches the intake's potential. There's a very simple reason for this. The MiniRam will always make more horsepower when combined with the right camshaft (224 intake duration for a 350 ... not the 218 that I am running now). The argument for the SR is for torque ... but, you can ALWAYS gain back torque through using the correct stall torque converter and the correct gears (heck, look at my 1.7x 60 ft times ... that is some nice torque). Its all a matter of taste regarding WHERE you want to make your power. If you want to make your power at lower RPMs then you agree to the potential of making less HP. 1/4 ET is dependent on topend HP and a very good 60' time. This means that you need a big cam, a high flowing intake, GREAT flowing heads and gearing (stall and rear) to give you crazy torque. Then you need to plant it all. Alot of MiniRam and non-MiniRam people forget about the drivetrain selection. A properly selected drivetrain for the MiniRam will result in tireshredding torque that results in absolutely awesome 60ft times if you can plant it.

A good case and point is a friend of mine who is running 12.0's in his naturally aspirated LT1. Its a manual and he is running trap speeds of 118mph. 224 cam and AFR heads. Trust me - this car has plenty of torque ... in fact, too much for street driving ... 1st gear is useless.

Well put trax i agree they both have there benifits and the MR may be a little better for 1/4. I run hedman LT header 1 5/8 but i have a custom 2 1/2 y-pipe that runs into a 3.5 mufflex exhaust. I would highly recomend a 3.5 or even a 4 inch system for your car if you plan on forced induction. Would you by chance be racing your iroc at bristal? I will be there but without iroc however tommorow i should get back to the track with my new alum shaft and loop, its been a while. I have considered driving my iroc to bristal 9 hours but if she brakes an axle or something I'am screwed. I will be there saturday driving my moms sweet 98suburban.

 

Supa,

I'll be at MIR (Maryland International Raceway) for their GM EFI shootout (also MAFB's Daragathon). I have to drive 100 miles there and 100 miles back. Thank GOD I have AAA!

Yea - I REALLY need a new exhaust. My current exhaust is really hurting me. Soon enough ... soon enough

Tim

 

how far is maryland dragway from state college central PA.

 

Do you know what the part number is for the miniram?

I'll be at the MAFB dragathon this weekend to, so I'll back thoose times.

 

supa,

Heh heh ... look in my signature. 12.24@112.5mph. If I had a manual I would be running 115-116mph

The MIR GM EFI shootout was awesome.

Trax i live in central PA and i realy would like to meet up with you at the strip. I can be at breezwood exit in about an hour and a half where is this strip? I would have no problem driving my car 2 hours to race. I to need 1 3/4 headers and i think at a good track i can hit 115mph. How long is this strip open for? My strip closes after this weekend for the winter. Do you know where altoona or Penn state is?

 

Supa,

MIR is an excellent track. Definitely one of the best ones I have been to. However, it is quite a ways. I have to drive 1-1/2 hours south just to get to it. I would imagine that you would have to drive 3-4hours

However - there is another good track that is much much closer. Its Mason Dixon dragway (www.masondixondragway.com). Check their schedule ... they have several TNTs coming up. I was going to put my car away for the winter so that I can begin some disassembly (remove tranny to upgrade to 3600 stall converter, pull off exhaust to prepare for LT header swap). But, I'll put that on the back burner if you want to meet up at the track.

You haven't said what year your car is? If its a '90-'92 SD car I could always hook you up with a good chip ... just let me know.

The biggest reasons that some tracks suck is because they are either not at sea level or because the traction sucks. Mason Dixon is pretty close to sea level and I've never had a problem hooking up there ... good traction.

Our cars would have a good race You definitely have the better exhaust with the LTs, the 2-1/2" Y, and the 3.5" catback ... but, I am setup so that I can get good traction off the line. I would definitely get the jump on you ... but, heh heh, it would be interesting to see what would happen after that Would be very interesting ....

trax

I was told that mason dixon is about a 2 hour drive. I'am pretty busy for the next few weekends. I have a knew buisness where i put on huge parties for frats and sorioties. How long is the track open for? I could go down on any sunday if its open then. What days do they race. BSD sucks because it goes about 20 fet up hill and has ruts at the starting line. I live in state college pa and go to school at university park or PENN STATE you have to know where that is.

 

my car is a 89 MAF. What kind of performance could i get with a custom chip?

 

Supa,

Mason Dixon is open as long as the weather is above freezing They will be open for quite some time.

As far as a chip is concerned ... it really depends on the current state of the car's tuning. You need to examine the fueling of the car over the 1/4 mile run (what are the O2's?), what is your timing advance over the 1/4?), etc. If you have a diacom run from a 1/4 run then send it to me and I'll examine it for you.

I don't have diacom. Where and how much for diacom? I have no data and have yet to explore any tuning of any kind. This is the one area of performance i have yet to educate myself on. I don't even know how to interprut my O2 readings if i had them.

 

Sheesh..im tired of watching the "i run with the best of them n/a" arguement. My 85 vette is a 383 forged bottom end, AFR 195 ported heads, Miniram, 1 3/4 supercomp headers, 3.73 gears, built 700r4 with a 2800 stall. Car goes 11.73 @ 119 on the motor and 126 on the bottle. Superram motors are very nice daily drivers and good streetable intake, but they arent worth the trouble. They are hard to work on, dont make nearly the topend power of a miniram and they are overpriced. My vette is my daily driver and blows away the tires at 80. Get the miniram if you are looking to run NOS.

 

I have asked this before, but since we are on the topic of super ram and mini ram, I want to ask it again since some of you here have one of these and can speak from experience. Which one would be best for me. I do alot of stop light racing and also like to hit it a 20-50mph and be able to really take a car. I have a 700r4 and I need to pass emissions and its daily driven. I want to make up my mind before I spend any more money. Thanks

Since you are looking for more torque for stop light racing, i'd go superram. But if this was my car, i would keep the TPI setup and just go with a nice lower intake (bigmouth are nice), AS&M runners, port the plenum to the runners and you'd be set. this would be great for stop light racing and still much easier to work on than the superram.

 

2¢ worth:

The Superram was designed by John Lingenfelter for small block Chevys in excess of 383 cubic inch. He did a great deal of R&D on all runner lengths and this was the best for killer torque & horsepower on larger displacement small blocks running up to 6000 to 6500 RMPs max. To get max power out of a setup like this requires carefull planning and all parts (cam, heads, etc.) set up for this RPM range. Smaller displacement motors must spin more RPM to make more power. So a mini ram often works better here. The mini ram is for high RPM use. It also would be good for larger displacement engines that are built to have a high RPM power range. Like large intake ports, long Cam duration & more overlap.
Nitrous Works well with both intake designs. The only problem I am aware of with the superram (and it's plenum) with nitrous use is this;

• The plenum is lage and the entire lid is bolted on to it.
  [*}If an improperly setup & tuned nitrous system backfires through the intake the pressure could strip the bolts and blow the top off of the plenum.
• A properly tuned system won't backfire!
• Nitrous backfires are caused by a lean condition.

I have seen The throttle blades wrapped around the throttle shaft from a nitrous backfire on a 4 barrel throttle body. Nitrous backfires are violent & can reak havock on an engine. The plenum lid can be a safety valve on a superram but on a miniram the throttle blades, intake gaskets, metal castings or any other part may fail under the pressure of a particularly nasty burp.
NHRA requires a safety pop-off valve on roots blower cars in most classes, and most racers use aluminum bolts to bolt the blower casing to the intake. That is so if there is a bad backfire it will shear the bolts and seperate the casing from the manifold cleanly without damaging the blower casing. The plenum top on a super ram could do the same and avoid damage to other parts.

Hey 89procharged, I can't really say that I stop light race too much. A majority of my races are when I am doing somewhere between 20-50mph to like 90 or so, and I wanna hang with new camaros and mustangs. So would you still suggest the ltr setup? See I get so many responses on this topic when I ask it but get an equal amount of them in favor of each the miniram, sr, and LTR setup. Some say with the right gears and converter the miniram is a good street combo, others say SR with 219 cam and afr's are great. So I dont know whaT to think. And I might eventually get to the track someday.
