the guy has got some kind of backing plate screwed on the plenum, can i just mount the stock bracket onto the plenum?

how does the cabling route around the box? thanks

 

There is a bracket made for the SR, not sure if it's normally supplied with it, but my SR(used) came with the bracket.

 

is it only one configuration that would work if so, can i see a pic? thanks.

the ports have beveling and gasket matching, looks factory, are they made that way?

 

I'm not sure , but I would think one could mod the stock bracket. I can't remember the difference to the stock one, might have just been the angle.
Here's a pic of mine, maybe you can see the difference compared to your stock one.

 

i think the unit is just as goodlooking as the tpi system if not better,

the holes for the bracket to plenum lines up, so far so good...

the stock bracket looks the same as yours, could you measure the angle separation of the 2 cable mounting surfaces,

the stock plenum does not have a bulge and i could use the cruise control, it appears with my bracket a kink would happen to my cruise cable and even the throttle cable.

 

I will check it out tomorrow.

 

never mind you have done enough, it looks the same, (the stock bracket) it's on the box and they'll put it together and hopefully i'll have a drivable corvette soon.

 

Nice setup Agent 86. Very impressive.

 

Stock Bracket is used.

 

thanx

Accel Part #74196 Superram Plenum/Runner Kit

WARNING: READ ALL INSTRUCTIONS BEFORE STARTING THIS INSTALLATION. FUEL LINES AND FUEL RAIL MAY BE UNDER HIGH PRESSURE, UNBOLT AND UNSCREW VERY CAREFULLY AS TO RELEASE ANY RESIDENT PRESSURE ON FUEL. NOTE THAT THE FOLLOWING INSTRUCTIONS MUST BE DONE WHILE VEHICLE IS COLD AND HAS NOT OPERATED WITHIN 24 HOURS. ALWAYS USE EXTREME CAUTION WHEN WORKING WITH ELECTRICAL, AND COOLANT SYSTEM COMPONENTS!

ACCEL SuperRam Plenum/Runner Kit is a direct bolt-on replacement but offers improved performance and fuel economy potential. Consisting of the Lingenfelter designed plenum and runners, this new SuperRam Plenum/Runner configuration significantly improves volumetric efficiency for more horsepower and torque. The plenum lid is removable to enable plenum-to-runner port matching. Optional billet plenum lid part #74198.

Please read the following instructions carefully before installing your new SuperRam Plenum/Runner Kit. Also we recommend that you study your applicable OEM service manual before you begin your installation. Please make a note of your engine configuration with special attention to all vacuum, fuel, and electrical connections for your future reference. It is a good habit to tag each part from your engine upon removal. This will help facilitate your re-assembly. If you have any questions or problems, please contact our tech line at (313) 380-1328.

Before beginning your installation, make sure that you have the following parts:

Supplied with the SuperRam Plenum/Runner Kit:

¼ -28 x 1/2 Button head screws
¼ -28 x ¾ 12 pt Head bolts
M8 x 25 Socket Head Bolts

RUNNERS

WARNING: FUEL LINES AND FUEL RAIL MAY BE UNDER HIGH PRESSURE, UNBOLT AND UNSCREW VERY CAREFULLY AS TO RELEASE ANY RESIDENT PRESSURE OR FUEL.

Carefully disconnect fuel lines from intake assembly. Watch out for spraying fuel! Be sure this operation is done on a cold engine.
Remove and save runner bolts and plenum assembly.
Push fuel rail assembly up to clear runners.
Remove runners and gaskets, save the OEM plastic locating pins for later re-assembly.

INTAKE MANIFOLD

Remove fuel rail assembly. Be careful for any residual fuel left in the fuel rail.
Remove spark plug wires and distributor cap.
Rotate engine manually to top dead center with distributor rotor pointing to cap location cylinder #1 and mark for proper installation.
Remove distributor.
Remove all fittings, sensor, etc… from you OEM plenum and intake. Please note location where removed from. This will facilitate re-assembly later.

REASSEMBLY

Install all sensors, fittings, etc… on your new ACCEL/Lingenfelter plenum and runners. Be sure to put sealer on threads. Install the two (2) 3/8 pipe plugs into threaded holes inside your new plenum. You should use Loctite 262 or equivalent and stake the plugs with a punch or chisel to prevent loosening.
Apply a thin bead of silicone to end rails and install intake gaskets.
Apply silicone sealer to intake manifold bolts and torque bolts to manufacturer’s specifications.
Re-install distributor, cap, and wires. See Figure 1 for cylinder location
You may be required to remove valve covers and rocker arms for cylinders 2,3,6, and 7 exhaust only. If removed, re-install rocker arms and set according to OEM specs.
Check alignment on runner gaskets. Some trimming may be required.
Apply a thin film of silicone to the runner gaskets, then carefully install the gaskets.
Carefully start the bottom runner bolts first (M8X25). Then slide runner over these bolts. Remember to always lubricate all bolts with an anti-seize compound.
Gently apply a small amount of lubricant to the injector O-rings.
Install fuel rails, but do not tighten them.
Install 4 – M8x30 bolts in the outside runner holes. Then install the original equipment runner bolts in the remaining holes.
On applications where the cold start solenoid is not used, a block off plug and plate with an O-ring is supplied. This should be installed in the machined hole in the drivers side runner and held in with a runner bolt.
Tighten fuel rail bolts
NOTE: On some applications the fuel injectors may slightly interfere with the SuperRam runners. To correct this problem you can increase the clearance by carefully filing the interference area with a file.
Lay T.V. cable on top of intake.
Apply a thin film of silicone to the plenum/runner gaskets and carefully install them.
Install the SuperRam plenum. Be sure to check that all sensors are installed and then connect the MAT sensor.
Carefully install the bolts from the runners to the SuperRam plenum. Do not tighten until all bolts have been started. These bolts thread up into the box.
Install the two original vacuum fittings, from the original plenum, into the rear of the SuperRam plenum. The 90 degree brass fitting installs in the hole of the driver side. On 1985-89 vehicles you should install the M6x12 screw in the small hole next to the vacuum fittings and the 1/4 pipe plug in the third threaded hole. On 1990-91 vehicles, this hole locates the MAP sensor. Install your vacuum fitting for the MAP sensor in the third hole. Be sure to apply silicone to all fittings to prevent vacuum leaks.
Carefully remove the fittings from the power brake booster. Remove the steel line and the factory vacuum hose. Install the 11/32” vacuum line. Some trimming may be necessary. The opposite end connects to the 90 degree brass fitting. This step replaces the OEM factory power brake vacuum line with a new rubber hose assembly. Be sure to carefully check power brake function before operation of vehicle.
Apply a thin film of silicone to the intake plenum box and install intake plenum top.
Carefully start all top bolts but do not tighten until all bolts have been started.
Install throttle body and gasket.
Reconnect all vacuum lines, electrical connections, and intake ducting.
Install valve cover gaskets and valve covers.
Carefully connect fuel lines and any coolant system hose.
Replace coolant.
Reconnect battery.

START UP AND CHECK OUT

Check TPS voltage.
1985-89 Idle voltage should be .54 volts
1990-91 Idle voltage should be .70 volts
Check initial timing and reset to 6 degrees (with ignition bypass disconnected) for best performance.
Please note: Retard timing if you have any problems with detonation.
Your Idle Air Control motor (IAC) may need to be adjusted to allow the computer to provide
proper idle. See GM service manual for instructions.

 

To anyone considering the Accel brackets for the SuperRam.

Be aware that there are two part numbers - one is intended for the
LPE/Accel intake for the small block, the other is intended for the big
block. (The BBC SuperRam is an EFI tunnel ram intake that is similar in
appearance to the Holley Stealth Ram - not at all like the LPE/Accel
SuperRam for TPI small blocks.)

SuperRam Throttle Cable Brackets (Accel catalog: pp 217-218)

• #74200: LPE/Accel SuperRam (small block)
• #74194: Accel SuperRam (big block)

Can't find my protractor, but using a square, I estimate the angle to be 125*.

Looks like the stock bracket works without any mods.

 

The positioning of the throttle, cruise and TV cables in the bracket
are all visible in the following photo of another CF member's SuperRam:
