Blower Milage

[larryf]

Well, it's been a week since I've had the blower on, and I've put about 75 miles on 1/3 tank of gas. I'll estimate that to about 10.5 to 11.5, where I'd normally get almost 13. So, this isn't too bad, since my right foot weighs about 3 lbs more than my left, since I installed the blower...

I'll be towing my 7,000 trailer soon, I'll let you know how it does, and I'll be sure and post my 1/4 mile times. My local track is having an open test and tune this Friday.

Larryf,

Had my S/C Installed July 16th and have a month to play with it.
Ok.. I got about the same as your reporting to start with. I am now getting around.... 14mpg avg. I can tell you this, I ran 80mpg on cruise for 200 miles with A/C off and got an amazing 17.8mpg.
Now.. around town.. just goofin' off.. I get around.. 14mpg. I live in LaGrange Ga. How is the power with the K&N installed? I was told by TRD that I am NOT to run that, it will allow too much air in and cause a lean condition and burn up engine and I am out of luck.

Anyway.. it gets better... Check out my photos!!!

Intresting they tell you not to run the K&N... TRD SELLS a K&N... It's my understanding that you can't get the full HP out of it without the add-ons. (Exhaust, Air Filter)... Mine runs like Jack the Bear, but it does ping still on Midgrade gas. I haven't put Super in it yet.

If it pings, I also get out of it...

I understand it, as Toyota says NOT to run anything other than the stock Air Box, they say nothing about the air filter... They say in the instructions not to use any "Cold Air Intake", as the MAF is setup for the stock air box. I don't see how the filter itself can draw too much air in. I'm working right now to see if I can match up any other Toyota or Lexus Injector that might put off more fuel to replace my 8 stock ones. With that, we might be able to kill the TRD piggy back ECU.

Larry,

If I were you I would loose the K&N ASAP...The S/C will suck the oil out of the K&N and it will build up on the MAF and inside the rest of the intake...This will cause the MAF to make incorrect readings...You can clean the MAF but it may still not work properly...Also run the highest octane pump gas you can buy it will only cost you an extra $4 or so, but it will save your engine and it componets over the long run. Just my $.02, hope this helps...

BTW...I have gotten a best of 15mpg with the S/C driving mainly city...the first tank was around 12mpg, but it sure was fun.

if you need custom injectors, check out RC Engineering.

[scdtrd]

It is not that easy to just replace the stock injectors and put bigger ones in. The ECU it is calibrated to the CC of the stock injectors and the fuel map is made to that spec. If you put larger injectors in, then the ECU will pulse the new injector (at 1st) to the predefined map point for that rpm and load. Since you have larger injectors, they will spray more fuel per pulse, BUT.. the O2's will see a rich condition and pull back on the pulse width, in order to reach what was stock in the 1st place. If the injectors are large enough, and the ECU can not trim the fuel pulse back far enough, then it will trigger a failure and well... you get the idea. The ECU has to be tricked into thinking the larger injectors are not there. ApeXi and others make good injector and MAF controllers. Check out http://www.gadgetonline.com for much more detailed info.

yup, you need a piggyback ecu and a wideband O2 sensor to recalibrate the new fuel injectors.

You really think the blower pulls that much air in? I though it was only putting off 5-8 lbs of boost to begin with. Probably less. I've read others that fouled thier MAF with a K&N, but I bought mine with the truck and have 42k on it, never had a CE light. However, I've only had the blower for about 100 miles. I did wonder what the suction might do to the K&N, cause you can sure as hell hear that blower sucking in some air. I just didn't think it would be enough to actually suck the oil out of it.

I still have my stock AF, I can throw that back in and see how it does. I'm also going with the 92 gas, as I still get some pings.

I love California. Nothing like $2.15 for a gallon of gas.

[scdtrd]

HOLY MOLY!!!
$2.15 / Gal for 92?

WOW!!

LaGrange Ga $1.59 / Gal 93

I feel better!

yes undeedie.... 2.05/ gal of 87

Larry,

Yeah K&Ns are prone to this with forced induction and not just on Tundras. It will tend to happen more commonly after you re-oil the filter, but it can still happen even if you have not re-oiled it. They just do not seem to "hold" the oil in. If you want a "performance" type filter like this I heard the TRD version works fine and another member on TS uses it. I do not use the TRD filter, the paper filters work fine for me....Wow $2.15 for 92, I pay around $1.63 for 93 and it just went up...

I was under the impression that the TRD filter was a K&N... Like Sears and Magnavox.

I'll check into the TRD one, however, with forced induction, I guess a paper filter will work, if the motor needs more boost, the blower /will/ pull it in.

You know, one thing I'm kinda disapoited about, is the lack of noise the blower makes... If you've ever seen a Top Fuel car run, you know 'blower sing'. I'ver herd some of the Paxtons do this, although faint, it's there. The Tundra doesen't do it at all, unless you are at WOT, then it sounds like a beast..

Such is life..

And yes, I live in Kern County, all we have are oil fields all over the place. If we ever get nuked, we'd be one of the first places to go, and gas STILL costs twice what it does in some places in the country.

I get 14 in city. I towed my boat last week. Went 200 miles. Got about 10 MPG. I was real heavy on the pedal though. You know, first time towing. I wanted to see what it could do. It was pretty awesome. The boat weighs just over 2000 lbs. and I went up every hill like it wasnt even there. Pretty impressed overall after 3800 miles on the truck.

[mustang67408]

I have 11,124 miles on the TUNDRA now WITH the S/C installed
NO problems.
10 mpg towing (lots of hills)(5000lb total)
14-17 hwy (not towing)70-85mph
12-14 around town
just my $.02
later
