Dyno Results From The Removal Of The Intake Butterfly

<tr>

<td><font size="3">I need to test this thing totally

stock before I go any further, that way we all have

something to compare our upgrades to in the future. And I

don&#146;t have to play guessing games.</font></td>

</tr>

<tr>

<td><font size="3">This test will be bone stock with the

use of Mobil 93 Octane in the tank. Nothing has been

changed as far as the oil or any filters go. I have about

1000 miles on the odometer, so the motor is still green

around the gills. I expect it to be slightly under what

it can produce after say about 4000 miles. But this

isn&#146;t a bad point to start. I took it down to EIP

Tuning in Westminister, MD which happens to be about

twenty five minutes away from the house. So it not a long

drive either. Gets the tranny and motor warmed up enough.

I have specifically asked the guys at EIP to take my baby

to redline. and thats it. I don&#146;t like to bounce it

off the rev limiter. Especially when the motor is still

very new. </font></td>

<tr>

<td><font size="3">The numbers are right in line with

RMM. All dynos will very slightly also. So you probably

won&#146;t get the same reading everywhere. Also this

dyno pull was taken in 4<sup>th</sup> gear. Now we all

have something to compare to when working on our

upgrades. Also remember my motor is still considered

green because it has just turned 1000 miles!! So it will

produce more stock in the future once the motor wears the

rest of the way in. And I can see a few more ponies if I

left this thing stock!!! Fat chance of that!! LOL </font></td>

<tr>

<td><font size="3">But totally stock @ 1000 miles it

pushing 153.3 horse and 114.9 ft/lbs of torque! Not to

shabby. </font></td>

<table border="0" cellpadding="5" cellspacing="1" width="75%">

<tr>

<td><font size="3">Very small increase with max output if

you take the butterfly valve out. .2 horsepower and .8

ft/lbs of torque. The good thing is the improved low end

torque which is about 2.5 ft/lb. </font></td>

<tr>

<td><font size="3">I am sure a lot of us have taken it

out already and been listening to the different noises

the intake makes now! And the seemingly better throttle

response!!! I am sure we expected more out of this. I

know I did! </font></td>

<tr>

<td width="100%"><font size="3">Well we had some time

left over from my half hour that my Visa card had allowed

me on the dyno So I wanted one more run in 5<sup>th</sup>

gear without the butterfly valve in it for the heck of

it. I wanted something to work with! It was disappointing

thus far. But we setup it up for more run! </font></td>

<table border="0" cellpadding="5" cellspacing="1" width="75%">

<tr>

<td width="100%"><font size="3">And to my surprise

without the butterfly valve the car made an extra 2.9

horsepower for a total of 149.6 and 3.8 ft/lbs of torque

for 113.3 and out did the totally stock airbox the whole

way!!! Great for high speed daredevils and radar friendly

drivers. So this is good! With about 4 more ponies across

the board and 3-4 ft/lbs of torque also most of the

way!!! I can&#146;t wait to verify what the RMM intake

can do for us over this!!! That&#146;s where things will

get interesting!!! </font></td>

nice writeup let us know what happens...I know I was impressed with the removal of the butterfly and also with the sea foam cleaning session, both together have made my 2000 gt feel a lot stronger and responsive r .... I was going to drop a GTS motor in mine but after finding out that TRD makes a supercharger for the 1zz motor...Im going to stick with the 1zz and add the supercharger
