Ive got a big mouth lower right now with the rest LTR setup. I bought a superram but think i might have gotten ripped on the lower manifold. Anyway i can tell if this is regular TPI manifold or accel piece? serial codes or anything? measurements? and even if it is, will the big mouth outflow the accel base and fit the superram upper and runners? Keep the Big Mouth lower on??
THanks

 

The Accel Superram intake manifold (base) has the name on the casting. It's near the top across from the firing order diagram. The letters are nearly an inch across.

All the aftermarket TPI bases are about the same. You don't need the Accel base. The TPIS Bigmouth is compatible and comparable.

I'd return or sell the Accel base since you don't need it for the Superram install.

 

Yes, the Accel base has its name casted on the intake. Your Big Mouth will work with the rest of the Super Ram stuff. Also, I have heard that the Big Mouth does outflow the Accel base, but I am not absolutely sure. Do some research on it. However, your best bet is to just return the Accel base, your Big Mouth intake base will be just fine.
