Superram installed- Now car "cams"
Just installed the superram upper and the car doesnt idle worth a crap. It hunts really bad and jumps from 550-800 RPMS even after warmed up. The only thing I changed was I did not block off the EGR pipe coming off the head, I left it open(maybe thats causing air to enter the head???. I also unhooked the egr solenoid on the driver side.
Anybody got any idea's???

Re: Superram installed- Now car "cams" (85superram)
Just the upper made a 2 carlength difference in power. I raced a 97 cobra with a few bolt ons 3 times before the install and I would out run him till about 60 MPH and then he would just pull away. Now I outrun him to 60 and hold him off so he stays a car back.....definately noticed the power.

Re: (ANTI VENOM)
Doesnt appear to be any but I havent spray checked them, will check them again though..... What about the egr tube coming off the head... I just left that open...could it be allowing air to enter the motor???? Only other mods are aftermarket dynomax mufflers, air foil, k&n and gutted maf and lid. The 85's dont have pre cats either.

Re: (85superram)
I can now turn the motor 5300 instead of 4800 like before. I notice a big SOTP difference, is this normal with just the upper???
ALSO... I reused my lower runner gaskets, but siliconed them... is that not advised????

Re: (85superram)
Thanks for stating your mods. I didn't notice any SOTP difference and my initial numbers weren't good but I am pretty certain the car is running stronger now. Maybe the computer has learned or something - I dunno for sure though. Mind you I was already using most of my other mods already when I didn't feel a difference.
With the stock base I don't see how re-using the old gaskets with silicone could cause a problem - as long as you have a good seal.

Re: (85superram)
Yes, you should be able to really rev it out more than before, but a cam and lower will help more.
If you have eliminated the leaks (make sure to test for leaks with starter spray-ether) then I would suggest that you follow the idle speed reset procedure in the tech tips sections. Follow it exactly, you may not get it to idle at 450, but set it to the lowest possible speed without the IAC connected, and then just a hair more once it dies. Then set the TPS voltage. Once you set the TPS voltage DO NOT MAKE ANY OTHER CHANGES. If you mess with the idle air screw after setting the TPS voltage, it will throw it out of adj. If you have to move the idle air screw to raise or lower the idle, make sure to reset the TPS voltage. I had idle problems after my install, had no leaks, and discovered it was because I was not following the proper procedure to set the idle. Also, you need to put on the EGR block off plate!!!!

Re: (85superram)
Are you using the stock heads and intake manifold? If so, there is no EGR tube that comes out of the heads. The EGR circulates internally through passages in the heads and intake manifold. There is no egr block off plate on your stock manifold. The egr solenoid is the gold vacuum canister in the center of your manifold under the plenum. Ensure that the vacuum reference line is hooked up to it properly.
The tubes that run out of your valve covers are merely PCV breather tubes that use engine vacuum to create positive crankcase ventilation. They hook up to the throttle body on the pass side and the intake manifold on the drivers side. They would not cause a vacuum leak.

Re: (scorp508)
I'm not familiar with the 85's EGR system. I don't know if it is the same as my '87. If I left the opening on my intake manifold for the EGR open that should only create a vacuum leak if the EGR valve was stuck open. Can you take a picture?

Re: (vader86)
I am using stock heads, the passages that travel through the intake are blocked by the superam upper. The gold solenoid does have a vacuum line going to it. The PCV lines are taken care of. The line i am talking about is on the drivers side and connected somehow to the back corner or the old plenum. I had to remove it and it is now open, it appears to connect to the side of the head....

If memory serves me right I had 4 total connections on my 87 plenum not counting anything from the TB forward.
1. Brake Booster Vacuum Line (Large & Metal, Rear Driver Side)
2. Fuel Pressure Regulator & EGR Valve Vacuum Line (Small & Hard Formed Plastic, Rear Passenger Side)
3. HVAC & Cruise Control Vacuum Line (Small & Hard Formed Plastic, Rear Passenger Side)
4. IAT Sensor (Bottom of Plenum)

Re: (85superram)
that metal tube connects to the power brake booster on my car , its basically a stock 85. im guessing your brakes are suckin a bit, lol. its not gonna cause an idle problem unless theres an open port in the superram upper its suppose to be connected to??

Lets try it this way.....
What do you have connected to your superram. Are there any ports left open still? There is supposed to be a brass 90* elbow in the back/left of the SR that you attach a 7/16" vacuum line to that connects to your brake booster. You replace the hardened line already there with this one.
