That's cool! I love that kinda stuff. I data log the Hellcat a lot (been dialing in the tune). I've got Torque and a OBDII reader, wonder if it would provide the data that program requires.

EDIT

Dang! I just went and looked up Virtual Dyno. I actually have an OLD version of that program from 2009. It used to be called TTDyno I think.

I know Torque does have a data logging feature but I can't get it to work right, I cannot export the files from my phone. Was going to overlay timing advance and open/closed loop status on my AEM data for a more complete picture but wasn't worth the hassle.

Got a replacement throttle body so I can keep driving my 4Runner while I get my throttle body bored at Maxbore.com throttle body boring service and repair. He said he's about 7 days out so I'm thinking it'll be close to 2 weeks or so when it's all said and done.

He will bore out the inside wall of the throttle body from 60mm to 63.5mm (12% more air flow) as well as a low profile throttle valve. I'm going to take a guess and say it will add about 5-10 HP to my engine.

Took some time when swapping throttle bodies to measure the sizes of my existing intake piping. Here's what I learned:

The supercharger itself measures between 62-62.5mm depending on where you measure (it's not completely round because of the bend). I was actually surprised to see it's bigger than the throttle body, which confirms my theory there's power to be gained with a larger throttle body. Not only is the stock TB 60mm, but it's also got a thick valve which restricts flow.



The maxbore TB will be 63.5mm which is just about perfect. Having it slightly larger than the supercharger it not a bad thing, since you want a slightly larger bore to equate for the valve itself and the flow it restricts.

The one problem I did encounter is the Airaid intake tube. It's only 60mm:



Thankfully it's plastic so gonna borrow a dremel and bore it out by hand as best I can. Want to get it at least to 63mm. We'll see how that goes.

I had my throttle body shipped off to Maxbore.com to be bored out slightly, have the shaft machined down and matched the intake of the supercharger. It turned out pretty good:



Stock size:



You can notice the thinner shaft. Here's the two side by side, notice the thickness of the IAC passageways on the bottom and the difference between the two:



Some measurement comparisons between the two:

Front

Stock - 66mm
Maxbore - 66.4mm

Middle (as close to the throttle valve as I could get:

Stock - 60.4mm
Maxbore - 61.9mm

Rear

Stock - 60.4mm
Maxbore - 63mm

I took it out for a few runs and overlayed it from a dyno from earlier in the year and noticed that it said I had lost 25 RWTQ! Confused, I remember that it was a day that had low humidity and in the 50's, and today was higher humidity and in the upper 80's! That's where my power went. So, no chart this time around, I didn't take a run before swapping the throttle bodies, which next time I will before a mod. Gonna take a guess on this one.

HP Increase:

+5 HP

Running Total:

+126 HP


I really, really need a new exhaust though. My power dies at 5000 RPM.

So no dyno charts, but I do have fuel trim data.

Pre-intake bore or throttle body bore, my long-term trims while under light to moderate throttle would hover around -6.4% to -8.0%. All that means is that it was pulling a small amount of fuel because of my oversized injectors. Now with the larger throttle body and larger intake to match, the are hovering from -4.8% to -6.4%, so they've richened up a little. And that's just at partial throttle. A higher fuel trim means there's more fuel being added to compensate with the extra airflow. I saw the same sort of jump, although higher, when I had the headers installed.

I can feel a slight difference driving it around town, but that's partially due to the junkyard unit I had in was bit dirty and gunked up and it's great having the ol' reliable one back on. Also, I noticed the new butterfly valve is air tight in the housing (very very well made) and has smoothed out the idle.

Can't wait for cooler weather to get this thing tested out for real.

If you guys follow my build thread enough, you'll find that I am willing to throw any sort of cleaner, fuel additive (I'm injecting water LOL) or oil in my 4Runner. Some I've had success with, such as Seafoam, others have been a bust. I tried a new product yesterday, Royal Purple's Max Atomizer fuel injector cleaner. I've tried other cleaners in the past, Techron, Lucas, and didn't notice a difference at all. Since I'm now a big fan of Royal Purple's Max ATF fluid (greatly improved shift smoothness with modified valve body) and their performance oil line, figured I'd give it a try.


It's a fairly small bottle at 6 oz, and contains a large amount of polyether amine (PEA at 85%) which is used in the more expensive fuel injector treatments you can have done at a dealer or private shop. I figured for $6.99, it's worth a go. My idle hasn't been all that great lately, it's got a bit of a misfire when it idles under 700 RPM that wasn't there when I put the engine in.

With only 20 miles since adding the the idle is buttery smooth again! Honestly, I was not expecting that at all. It feels like I did when I first put the engine in back in January! I'm not sure if I had something lodged in an injector or it was just deposits affecting the operation of the injectors or what, but this was well worth the $6.99 I bought it for! Looking forward to running through the rest of the tank and see if things improve more.

Follow up on the Royal Purple's Max Atomizer fuel injector cleaner. After the first tank it ran amazing. By about tank 4, so roughly 1200 miles after adding the cleaner, the misfire at idle returned. I put another bottle in so let's see if using it more frequently cleans better. Idle is smooth again after adding the product.

Went camping with the wife and kids on the Oregon coast. First time out on the sand! Found out my H/T rated tires kinda suck in loose sand, didn't get stuck though at least. Was good times with the family.

I should also mention that my 4Runner loved the 92 Octane fuel in Oregon. I'm going to goof around with some Boostane and running some 94/95 equivalent fuel.

I requested some possible seat belt samples from a company. Thinking of adding some TRD red flair to the interior of my car. Probably will need to add some red beyond just the seatbelts though. Any thoughts? I kinda like the Elegant Red Panel, but the Ferrari Red I think is closer to the TRD Red color.

Tried out another product today. I installed an electric fan a year or so ago to free up some HP by reducing rotational mass (the stock mechanical fan) but under some circumstances the fan couldn't keep up. One instance was during stop and go traffic across Sacramento on hot summer days (100+ degrees on the road). Certain roads like Sunrise Blvd. and others have long stop lights so idle temps plus constantly being on the gas made for a very hot engine that the fan could not cool down fast enough. Would hit up to 210 degrees, for a boosted engine that means ping, ping, and more ping!

I put in some Royal Purple Ice, which is a coolant additive that helps reduce temperatures. Along with the Ice, I also increased my water/antifreeze ratio from 50/50 to 60/40 per recommended. This product can also be used in straight water.


Water transfers heat from the cylinder heads and block faster than antifreeze but has diminishing returns. One research article shows that pure water carries away twice as much heat as pure antifreeze but a 50/50 mix is only up to 20% less efficient than straight water. Royal Purple Ice and other chemical additives like Water Wetter reduce surface tension, eliminating some of the barrier that keeps water from absorbing heat from the engine. This doesn't "magically eliminate heat", it's a by product of a combustion engine. What it does do is move more of that heat from the engine block and heads to the radiator where it can be transferred into the air via the radiator.

For me cooler engine temps = less detonation, which = more timing and more power. I'm not as worried about running at cooler temps since I've had the 170 degree thermostat in my engine for 5 years with no ill-effect, not surprising since it's made by TRD.

The first few days of driving my electric fan it kicking on less. In fact this morning while driving to work, the fan did not turn on once during my 5 mile commute with about 70 degrees ambient temperature. So far I'm pleased with the results but I need a good hot day to really put it to the test and see if I can stay out of the 210's. Today is 93 degrees, hot but tack on that extra 10 degrees and it makes a big difference. More to come!

Just watched the final video series of a Turbo V8 LS swap into a Tacoma. Sometimes I pretend my 4Runner is fast (it isn't). Skip to 5:00 mark if you don't like the theatrics.

Been meaning to comment on this, my supercharged 4Runner also makes a tick more boost in numerically higher gears like 3rd for example than 2nd.

I think it's because the RPMs aren't climbing as fast and boost is somewhat an example of restriction. The RPMs climbing faster in lower RPM frees up some restriction and I see about 1psi less boost.

I call my 09 Tocuma the Turd but that was more TRD because it had a TRD cold air intake on it.
