after superram install... :(
Trouble-shooting sucks no matter the manifold. Let's keep this on topic...
You can also try smoking a cigar and blowing it into the manifold through a tube in one of the holes. The smoke should come out from the leak. Or use a smoke machine to do the same thing or use it to make a lot of smoke around the manifold then start the car, this should also flush out the leak. I like these more than the starter fluid as it is a lot less dangerous!

Yep u never installed, after pete k installed SR (lower n upper) i never had to chase vaccum leaks or anything, drove 12500 miles sofar without worrying about vaccum leaks.
Infact pete k did not use RTV silicone and Lpe gasket. He use glue and home made paper gasket and grinded 2 bolts going underneath of SR plenum, that bolt was too long (big chances of vaccum leak here).
Note: Instead of spraying for chasing vaccum leaks, find out if any mechanic in ur area has "snap on" smoke detector machine, my mech has it and he hooked up to brake booster vaccum lines, take off intake (whole filter area and maf) and block off at the TB coupler. When turned ON this m/c, this sends lot a smoke to all vaccum hoses and if any leak is present u will immediately see smoke coming out a that leak. It is safe, easy and guaranteed to detect any leak. Whole this process will take not more than 1/2 hr. Goodluck.

I got a used SR base about 3 years ago, the plenum & runners kit NIB on ebay about 2 years ago. Everything appeared to "pre-fit" real tight. My mechanic installed the entire intake in 2 hours (he never did one before), the standard way per the directions. No tricks. All DRY gaskets. No leaks, its been about 10,000 miles so far.
Maybe it sounds like my luck will run out, per some of these stories I read here. Maybe a huge leak will occur out of the blue, the A/F will lean out so severely that the ECM and SD calcs will be far exceeded and my engine will literally blow up right of the hood going down the highway some day next week.

I agree with you regarding the quality issue. Thats why I say I must have been lucky, in that the parts were just "old" enough. I was just kidding about the engine blowing up (again).

Sounds like he's a good and honest mechanic. I guess two hours is right if it is already dismantled. A safe and happy holiday to all.
Thats why every one wants you to install the runner to base bolts but leave them loose untill the plenum is on. But that to me is not the best way to get a good seal, remember all the bolts are going in to aluminum and now your trying to pull parts together that don't fit right.
I found that some of the runner to base bolts were to long and I found that the head on the 4 bolts that go in the bottom of the runners were keeping the runners from going down all the way on the base. After cutting down the bolts and grinding off some of the heads the runners fit the base great.
The way the plenum is bolted to the runners is a weak link and a pain in the a$$ you can't tighten the little bolts they give you enough with out stripping the aluminum threads (remember you are trying to pull two pieces together that don't fit right). I bought my SR used so it all ready had the common mod to the inner two bolts so you could install them from the plenum down, but you were still using aluminum threads. I went one step farther and drilled all the holes in the plenum and runners so I could install bolts from the plenum down with aircraft nuts on the bottom. This way I can install and tighten the runners to the base and then the plenum will fit right on the runners and the holes will line up. One of the factory holes in the plenum was so far in the corner I could not drill it and use a bigger bolt so I had to leave it alone.
I can dismantle the SR and reinstall it in under 2 hours. I have had mine apart at least a dozen times and have never had to changed the gaskets and never had a vacuum leak. This is the bolts I'm using for the plenum to runners, I think they are 1/4 x28.

P.S.
I am also using the SR on Vortec heads even though every one will tell you that it will not fit.

It gets even easier if you run a tap through the bolt holes to clean the threads. Go one step further and thread the inner holes and the thing becomes a dream to install.
The OP most likely yes is suffering from a vacuum leak or in need of an ECM calibration. The stock calibration will run with the SR, but will not be optimal.

I never said the superram was not an excellent intake system. It is just a pain in the *** to install/remove and if not done correctly it will be a nightmare to remove, reinstall (if you have to).
I remember most of the s/r install tricks. When I did mine back in 2000 the rockers were not removed, the top bolts bolts were slotted so I could screw them in from up top, etc.
If it were not suck a pain to install i'de proabbly still be running one. But why when there are optoins such as the miniram. Here is what you have to do to remove the miniram:
1. Pull distributor
2. Remove coolant line from front of manifold and unhook radiator hose from t/stat neck.
3. Unhook injector wires, iac, tps, map or maf (depending on app)
4. Unhook throttle lines to throttle body
5. Remove air filter housing and elbow connecting air filter to throttle body
6. Disconnect fuel lines and vacume lines
7. Remove 12 screws holding manifold to cylinder heads
Im done in about 1/2 hour. Show me somebody that can pull the superram from the upper plenum, runners, and base manifold in 30 minutes and i'll give them my '85.
I am not trying to start a super ram vs miniram vs singleplane, vs h/s/r but it is what it is. The super ram is a pain in the *** to install....period.
I hope everyone understands that every combo is different and of course has it pros and cons. And mainly the author of this thread gets his issues resolved.
