It will absorb the heat of the compressed air.

On the 7th inj kit. how much are you all getting it for?
since I do not have my dsl at this time I cannot surf around... dial up sux:cry:

 

There's one up on eBay now with a starting bid of $1050. It looks like it's a relisting from a previous auction that didn't get any bids with a $1095 starting price.

 

$1147 + Shipping (-$20?)

Hey Peter,

You should try the Auterra Dyno in my signature. May not be as accurate as a shop dyno but it will at least give you a comparative baseline, is relatively inexpensive and is very convienent. I am quite curious to see how it comes out so keep us posted!

 

J -
Okay, okay, I ordered the software this morning, so now we are all in big trouble. I usually order this kind of stuff, like Desktop Dyno, Dyno 2000 and never use it because it is too complicated for my little A.D.D. mind to work through. If I get it hooked up maybe it can at least tell me about the airbag trouble code light I have now. Wish me luck.

 

I just got this exciting message from CONICELLI Toyota about TRD's fantastic new offer on the Supercharger Kit.

TRD announces a permanent reduction in the price for the 3.4L V6 Supercharger Kit, available starting today for $2095.00 This new discounted price represents a 21% savings over previous cost.
Same Great Power, New Great Price!!!

Some one must really be stuck on that 21% number:
21% peak HP increase with 7th Injector kit.
21% discounted price.

Well, maybe you won't find this funny but I think it is ironic. Yeah I know, it is a slow day around here.

 

Does it include the 7th injector?

Chris

 

 

I bet you will use it a bit more than the others just cause it is so portable. If ya don't like it it is very easy to unload on eBay and you won't lose much on the sale. If you were closer I would just lend you mine to try it out.

 

J -
I am sure that I will use it; it is just that I hate reading manuals and have very little patience. If I have any problems I know I can get support from you and I will report to the board what I think of the product after I have given it a fair chance. Thank you.

 

Does anyone know what the overall gear ratio (transmission and axle) is of the late model 4R with automatic transmission?

Also, what is the FRONTAL AREA in square feet and the DRAG coefficient?

I need to know these numbers in order to setup the Dyno Operation of the Auterra Dyno-Scan software.

 

Hey P-

Curb weight should be around 3975+ lbs maybe more if you added stuff to yours.

There is a program in auterra that will caculate the gear ratios for you, just enter those when you calculate them. Just uses tire size and engine rpm to figure it out.

All the environmental stuff you can get locally (elevation =0 on the cape, temp, humidity, pressure)

The drag coefficient should be around 0.38 - 0.39

As for the frontal area you can just measure the height and width (of the main body of the vehicle, not wheels too) and multiply them together (if you measured in inches then divide the area by 144 to get sq ft). Should include just the area of what you would see looking straight at the vehicle (you can include the roof rack, mirrors and tires if you really want to be picky).

Just remember all the setting you put in so when you compare it after the install, you have an apples to apples comparison.

 

J -
Thank you.
I am so damn impatient that I want to just do the install w/o taking data beforehand, but I will try to restrain myself for the common cause.

 

I looked up the Curb Vehicle Weight of my 4R and it is 4,115#. I will probably figure 4,350# for testing purposes, unless I have a co-pilot helping me. :pat:

The definition of CURB VEHICLE WEIGHT is:

Curb weight means the actual or the manufacturer's estimated weight of the vehicle in operational status with all standard equipment, and weight of fuel at nominal tank capacity, and the weight of optional equipment computed in accordance with § 86.1832-01; incomplete light-duty trucks shall have the curb weight specified by the manufacturer.

Therefore, I have to now add the weight of any modifications, like push bars or my subwoofer as well as the weight of the driver (and passenger). I remember when I was playing around with my wagon, I took every damn thing that I generally carry out and weighed it, as well as myself and then took it to a truck scale at the local land fill. Truck scales are not suppose to be as accurate as race scales but they will do in a pinch, especially if they have been calibrated recently.

My tires are P265/70R16 which compute to a rolling diameter of 30.60.

PS: For anyone reading this, here is a little tip to add peice of mind. I just replaced the 4 rusting self-threading screws that secure the license plate lamp lenses on the rear hatch. I used Phillips head stainless #8 - 5/8 screws and they fit perfectly. I guarantee that if you look you will see that they the screws on your ride are rusting and discoloring the lenses. JM2C

 

Sry, you're right....that curb weight was for an SR5 not a limited.

Let us know what you get for numbers...I havent had time to play with mine yet.

 

I found a good price in the inj kit . 1104.15

Peter;

Like MTL said, the Auterra software will compute the final ratio for you. The software has been updated from some of the original docs where it wanted the gear ratios for EACH gear plus the final.

I'd be curious to know what you compute. With my 265/75/R16's the computation floats, but I've been using 3.254.

It wasn't clear in your post, but is the 4115 number your result from the truck scale? if so, that's interesting - based on some info I've found on the 'net, I guessed at 4130.


Note: When you do an acceleration run, be sure to open up your Dyno file first. You can _not_ apply an updated Dyno file to an old run. Auterra and I have been talking about this issue, (and a few others) and it should be addressed a bit down the road.



If this side discussion gets too much longer, we should start a new thread. We don't want to steal this topic.

 

Mark,
I could not respond until now because I was out of pocket for two days and the site appears to have been down yesterday. I want to get on a truck scale ASAP. I am resisting installing the injector kit until I can get some numbers, but it will probably take me a little while. The numbers I came up with for our vehicles (Medium SUV – SR5) pertaining to Drag Coefficient and Frontal Area, according to the engineering study at the Univ of Ill, are 0.45 and 31.21 sf.

This month is very busy for me. I see that Mr. Gadget has introduced his kit and it includes some parts that surprise me ... the thermo and the 2-step colder plugs, but I am sure it all makes sense to all you techies. I am trying to speak with my contact at Magnuson to ask some questions and see what they have discovered after installing a kit on a Tacoma. TTYL, Peter

 

Ahh! Real numbers! Yay!

Did you find those on the 'net? If so, do you have the link handy?


This'll be interetsing info to find out, just the 2nd set of results thus far. Like I'm sure you read above. Rob (WATRD) has gotten some very nice results on his truck.


Thanks Peter!
