Sweet looking setup!!!
If your car is an n/a then my only question is...did you have your 5th and 6th intake ports blocked off/air pump actuated/or perm open? I know I'm new and all...but all over this forum I have read that you need exhaust back pressure to trigger the actuators for your 5th and 6th intake ports. Without these ports you will lose alot of your top end power. The car will try to run more fuel, but will not have the correct amount of air flowing in...therefore run rich. Along those lines, if the 5th/6th ports are perm open, then you will lose a lot of low end power by running too much air and not enough fuel. Rotaries + Lean mixture = bad. Again this is only what I have read on this forum. Or I might be crazy and missed the part where you dealt with this problem. In either case, write a post and let me know how the car feels. Again sweet looking system. |
nice pics, congrats,.

Again sweet looking system. i never thought of that but now that you say that i have noticed that i am running a little bit richer. is there some way that i can correct this problem? if you or anybody knows please let me know....thanks Jack |
will disconecting the air pump have anything to do with the 5th and 6th ports? i am running the stock catalytic converter (or whats left of it https://www.nopistons.com/forums/pub...DIR...) so i still have that little pipe coming out of it hooked up. is that the thing that opens my 5&6 ports? what can i do to ensure that i am getting optimal performance out of this mod?
