Just had to give a to the guys at Apten.

HOLY COW I've gained a solid 3psi on my autometer guage and I like the sound at idle / just off idle. THAT's how a blower should sound. It's got a nice little whir going on.


Guys this is a must do. Definately a very good bang for the buck.

THATS WHAT I'M TALKING ABOUT

WOO HOO, isn't this the greatest Mod Rich,
CONGRATS

How you like that extra Mid and Upper pulling power,
SMOOOOOOOKING aint it.
BTW
As for that lovely NEW AND IMPROVED whine,
I can make mine whistle when I pass pretty girls on the
street by playing with the gas pedal

 

There goes Rob again, playing with his gas pedal as usual.
Keep it up pal and you`ll go blind.

 

Does anyone have a video clip of a truck with a ported eaton at idle and getting on it? I need more whine so it will overake my exhaust sound

 

LatemodelRacer2, It's not THAT loud. Honestly I'd say it's only about 5%-10% louder. If the radio was at a low volume you'd not even notice it.

If I get a chance tonight I might make a little vid.

You gotta love that mod I gained boost too, but in reality you probably aren't really seeing 3#. Probably 1/2 of that is weather related I am guess. We'll both see how much the gauge reads in the middle of summer

 

I'm a automotive engineer in Motown (with induction design experience btw). I *think* I know the differance between a 38-39 degree WOT session after porting the blower vs a 38-39 degree WOT before porting. Oh and the humidity levels were at about 55% last night too.

So in **reality** YES I am seeing a solid 3# increase on a hot motor & in like conditions.

Rich

 

I have no "proof" because I do not know what I was at before (boost gauge went in after the Apten). I am now hitting 15-16#'s though. But we'll see what that is in the middle of August lol

 

ROFLMAO....

 

Rich,

Did you do anything to your tune?? Or do you plan on it??

I e-mailed REM this morning about it & antisapate sending it off this week. I wanna keep-er safe

Last night I took it for a short drive to let it everything thermocycle once before putting it under a full load. Then later I made 5 total blasts up til just after the 2-3 shift. 1st time I saw 17psi (cool motor) and the other 4 it hit 16 right on the nose.

Oh and the rear tires don't hook on the 1-2 shift anymore (hot motor)
Steer with the rear baby!

Rich

 

I don't have a sound clip either, but mine is more than 5-10% louder. It's quite a bit louder under part and full throttle than the stock Eaton. I just replaced mine with a KB and it's VERY quiet in comparison to the Apten.

Jody

 

Hum.? I wonder if nime will get louder with more time/wear? Afterall I only have about 6-7 miles on it since the Apten porting. Maybe I'll change my opinion after driving it a few more times..

Rich

 

Rich,

My truck has 100% stock exhaust so any noise increase is very apparent. I'm guessing you have a cat-back or other changes? Mine was louder from the first drive, it didn't take any time at all to notice.

Jody

 

I took it for another spin today. I'm still of the opinion that it's not that much louder under acceleration. However I do think at idle it is clearly noticable inside the cab. And downright unmistakeable from outside.

I took some sounds clips for anybody who might be interested

All I do is start the motor, idle, rev to 1500, rev to 2000 give a little blip up to about 3500, then return to idle. (mike is about 5ft in front of truck and shoulder height)
