Excuse my ignorance but are you are saying that removing the cats didn't make any difference unless you rev it like the space shuttle?
Pretty much? At least no noticeable gain at low rpm

I noticed a gain at low rpm. Then again my cats were really clogged..Pretty much? At least no noticeable gain at low rpm
mine is rarely over 3k. this is weird to watch.
What's wrong with 5 grand? Toyota put the limiter at 5500 for a reason
5000 RPMS???? What is this, an Integra Type-R? You guys treat your Land Cruisers massively different than most of us over here. Awesome to see.
Anytime you improve air flow through the motor the power range shifts up,cat delet,long tube headers,port work.inline motors have inherent good torque in lower rpm ranges.so here you have the best of both worlds.
good work,get rid of that rev limiter.
That sure seems like a horrible idea for little to no gain.Just did a airbox ghetto mod , removed the fender cover, in hopes to feed the 1fze more air , ambient temperature air. Hopefully denser charge of air.
or just more debris and water
I really do find alot of joy with tinkering
Be sure to clean your filter more often now @ALBO

pretty much then you start getting into,cams, piston design,fuel delivery.a large oval or round port =less restriction until the exhaust cannot scavenge any more then it starts developing back pressure.balance is the key.with direct port injection you can move lots of air.Is it really a direct correlation? More airflow , power band shifts up and vice versa ? I think there is more to the story
Velocity vs restriction ? Larger diamter more flow and less back pressure BUT less velocity and less scavenging ?
Why was I under the impression that back pressure doesn't really matter in gasoline, 4 stroke IC engines? Or that you don't need to have back pressure present in the exhaust to get power? Especially on NA engines. Turbo, different story.
