  6. Took car to track... Confused...

    in Engine and Performance - Anything for that couple extra horses!

    Could be a number of things, like conditions at the track, temperture, track prep, ect. Street numbers and track numbers are two completely different things. Lots of practice and good track conditons is essential. Looking in the other direction could be the car as in things like fuel filter, air filter, plugs / wires, little things like that can hinder performance alot, even though you say last owner took care of it, never know how many miles can be on that stuff.

    well took car this morning to a street where i could stop and go 0-60 and i ran it in 9.4 that was on the street but i am going to be changing all the spark plugs and the fuel filter then will retry it... i might get the spark plug wires changed also...

    the track isnt very even and they spray a lot of that grip stuff almost halfway down the track... i would guess its the track then...

    okay i have a 2002 lexus is300 automatic transmission.

    the car was taken care of by previous owner and was garage kept and was in perfect condition when i bought it month ago.

    I took it to the track near me which is a 1/8 mile track and i run 10.4 to 10.6 at about 64-67 mph... if my car is rated for about 7.4 from 0-60 why does it take over 10 seconds to do 1/8 mile at 65?

    It doesn't work like that. By lengthening the port you're adding displacement which reduces box volume. Reducing box volume raises tuning. By my calculations you're still tuned around 45hz. It's is imperative to recalculate box volume after any port changes.

    dude i tuned the port by entering all my calculation into the port calculator on REs website and i think it would be tuned to 36hz if i put in all my calculations then did the box exactly the same as the calculator... so its tuned to right somewhere around 36 hz give or take a few numbers.... but trust me its not tuned to 45hz anymore thats about where i had it before and lower notes sound better now....

    I'm curious how you "redid" the port. What are you're exact box specs? That last note is way lower than your 36hz box tune. Playing below tuning = bottoming out sub.

    okay i redid my port by basically taking the top of box off and undoing the port pieces the used calculator to tune it to the correct frequency... my box was tuned to 45hz before and now its tuned to about 36hz...

    ok on the last note of I Put On still sounds bad... i redid the port and used the RE Enclosure Calculator to tune the port to 36HZ and that last note on I Put On still sounds like it is bottoming out and i have my amp set right and i have it set to rms rating for the speaker put on it...

  22. Best box for a 2002 lexus is300

    Try to perforate the rear deck and carpet it with breathing carpet if u know what i mean.

    Edit: i may assume the rear deck is made out of steel. I did the same on my dads benz few years ago.

    how would you wall it if seats dont go down? you mean like taking out the back seats or something?

    I dont really want to wall it though i would rather go with something that just shoots everything out of the armrest or through an area between the 6x9s like someone else said... if i cut out an opening up there and put breathable carpet it would be louder already...

    I drive a lexus is300 and it really makes me mad because my sub is really loud but my seats dont fold down and the only thing that really lets bass through is the two 6x9s and the arm rest on the back seat that folds down and has about a 7 inch by 5 inch opening... what are some ways that i could beable to have a lot more sound come through???

    I was wondering if a custom bandpass box where all the sound ports through armrest would be a good idea???
