l27 air filter box

[Guest the chad]

Is the 91-92 na bigger and could it be fit into a ln3?

[jonlabree]

Are you looking for a bigger filter or more air flow?

[Guest the chad]

more air flow through a bigger stock box. I thought I read one of the moderators stating the L 27 3800 had a bigger box.

I removed the restrictor at the front and put a 3" piece of PVC and used a K&N filter. I have no problem getting air into the engine.

More air helps a bit, but if the ECM is not reconfigured the use of the air remains pretty much stock. I see this on many little honda and other such "tuner" cars. Spend $500 expecting 50hp, but they never change the fuel maps, and on see minimal increases.

Also the LN3 is limitted internally by valves and the small throtle body inlet.

If you got no increase, then perhaps you should contact GMtuners and have then reprogram you computer. I have a controler on mine that alows me (at this tome) 4 different set-ups for the computer.

Already have it tuned. I was speaking of those who add all these go fast parts and never tell the computer how to use them.

Daniel; I was speaking to Chad. I wasn't telling you what to do.

Sorry did not read into it that far, but you are right.
