SAE ??? isnt that a measurement of viscosity ???

Like others have said...nice dyno runs. What were the oil, radiator, and transmission temps at for both tests and what's the calibration error of the machine (1st run of the day from cold vs. last run after being abused)?

You're showing a 12% improvement over stock at 4000 rpm!

Let us know if your MPGs go up (improved efficiency) or down (extra skinny pedal)

[Taco04]

Your dyno has a correction factor but I am used to MD's or dynojets in the past on other vehicles so I am trying to figure the correction factor out...

Honestly it's nice to see You actually dynoed it! This is a big step towards some Real Data! Any way A big Thanks for sharing your time and money on this with the rest of us!

I didnt go that deep into it... this has been the same shop, same dyno and same tuner / dyno operator for the last 3 cars Ive built. So I have trust and belive in the numbers the dyno has put out in the pass...

Just from the intake its gone maybe 1 or 2 mpg... we'll see how she does when I head to Phoenix in 2 days... She did 21mpg last november.

It does feel more drivable with the intake and even more with the exhuast. But the improvement was as noticeable as it was going from stock to intake.

I'm going to recant on my statement of the exhuats being aggressive. Ill keep it alone because it seemed to quiet down after the 5time out today. But might have to add a resonator later with the URD Y pipe.

[Taco04]

I am glad to see you you are throwing some real numbers behind it rather than the "Old Butt Dyno"! Thanks again!

[Dirty Brigade]

Yea, great numbers. Not many people are putting there 4Runner on the dyno. Nice looking too, love the TRD front end. Might have to get one of those.

I also had the muffler shop modify the rear section and have them tuck it closer to the frame...


heres the pics :

Rear section modified, shorten, and tucked...

Hey nice sound but if u do go to the 70 please post a sound clip. I'm trying to figure out which way to go with mine as well. Thanks

I might have thought the 50 would be a little ricey but not bad ! I went with the 70ii on the 05 V6 & have been very happy , so I thought when I did change it out would go same route but now thinking 50 might be ok . And I would say yes on the urd y-pipe it will change sound .

on my way back to Mike's Muffler and swapping this out with a Magnaflow 22" part # 12576 will post vids later on today

its definitely has a nice deep rich tone over stock...

with the super 50; I felt more power at top than stock but it felt torque-less down low.

with the magnaflow; I feel alittle more torque down low than stock and alittle more power up top ...

but this is just my butt dyno ... which is pretty good track record so far...

but will verify on the dyno when I get back ...
