Hey guys,

I have an 88 350TPI. I started working on the air intake because its very restrictive on the engine, but im wondering if i may have gone "too far".

I took the plastic part that the air filters sit in and cut out the "boxes" that were under the filtters, opening it up big time. Noticed a big difference there! I took the "Y" intake part out and cut rectangular windows into the back of it to help it breath a bit better, noticed a difference here too. I cut the rear screen out of the MAF, but decided to leave the front one just to air n the safe side;the car is my DD and i figured it wasnt worth the minimal gain to cut that front one out too. It definetly pulled alot stronger, and the throttle respone was crisp and more powerful than ever!

I ordered a throttle body air foil and intalled it, and now it feels pretty much like it did stock, if not worse. It feels completely drained, the torque just dropped like a rock. I was really expecting it to make a huge impact on the amount of torque, but in a POSITIVE way of course. I used to burn rubber so easily, i could be going thru a corner 15-20mph and give it some gas and still break the tires free; i tried the same thing at the same turn and it didnt even break free.

Could I have made it run too lean? I thought the computer adjusts the air/fuel ratio so that it couldnt run lean though? I appreciate any imput on this.

In the meantime, im going to put the uncut Y intake back on and see if that seems to make any difference.

Thanks again guys!

 

I put the uncut Y intake back on and it seemed better, but still not as powerful as before.

Do I need to reset the computer (unplug battery/pull fuse) so it resets itself?

Im just a bit lost and frustrated here, i was really expecting a noticable of power gained here but instead i feel like i lost a considerable amount.

Thanks again everyone
