Building a New VE Table

VE-blower This is what I spent the better part of today working on, the VE table for Quadzilla. I’ve done this before, but now I’m dealing with a 2-bar OS, so I have double the range of pressure variables. There are two ways to go about building this table, one uses a wideband AFR recorder in open loop mode, and the other uses the factory narowband sensors in closed loop mode using the fuel trends. I did it both ways, and got different results, which is a symptom that I’m doing something wrong. I also got different results when the MAF sensor was plugged in, even though I had it ‘turned off’ in the computer. After hours of reading through the forums, I think I have a handle on that situation. I have the non-boost regions (under 110kpa) tuned in, but I’m not sure how I’m going to get the cells above 4psi dialed in correctly. My alcohol spray comes on around that point, adding ‘undocumented’ fuel to the engine, which is lowering the AFR a significant bit. I have more learning to do for sure.
VE-stock This is the VE table from the factory. Comparing the two gives you an idea of how much more air the supercharger adds to the process. Notice the stock engine peaks at around 105% at around 4500 rpm. The regions I have tuned correctly are already around 150%, not sure what the real number will be at redline.

New Pulley for Quadzilla

So after a day of going through the vacuum system on Betty and failing to fix the transmission shift problem (but learning what all those plastic hoses go to), I decided to spend a little time on quadzilla. I’ve had a noisy belt problem for a long time now, so I figured it was a good time to get that resolved. I also wanted to change out the supercharger pulley with a smaller one to get a little more airflow, you know, because airflow is a really good thing. As usual, my driveway started to accumulate parts.
img_4825 Fan shroud, supercharger, filter, and the FMU (gone for good). The engine compartment looks empty without all that stuff in there. img_4826
img_4832 I cleaned up all the oil and grime and put the blower in the vice to make the pulley change easy. (you pretty much have to have an impact wrench to get that pulley bolt off). I also replaced the top idler pulley; it was starting to feel rough. I think this is the 3rd one I’ve replaced. img_4841
img_4833 My pulley collection. Original was 4.25″ and produced 8psi, the second one is 3.7″ and made about 10psi, and the new one is 3.4″. I don’t know what it will do yet, my tune is not up to snuff and I haven’t pushed it yet, but I did notice more bypass chirping noise at 70MPH today, so I know it is blowing more air.
img_4842 The Procharger rep couldn’t tell me what size of belt I needed. He said it would probably be a 111.5″ or a 111.0″. img_4843 The second picture shows my old 111.625 belt (probably stretched a little) with the tensioner held off all the way. 1.5″ of deflection over a 6″ span is how much belt? (I’ll have to ask some of my smart friends to solve that one) I did solve my belt noise problem. I took a toothbrush and degreaser to all the pulleys and the belt too. Total cleanness seems to be the secret.

My Trench

I’m pretty hard on anyone, especially my wife, who can’t manage to drive on the driveway, getting off in the grass, packing down the soil, breaking my sprinkler heads, etc.

The observant-type might notice 1) someone can’t stay on the driveway, 2) those tracks are from BFG AT tires, 3) Amber’s car is parked (poorly), so they didn’t come from her. Yup, that was me. Many excuses (dark, couldn’t see, Amber was parked too close to the middle, 4-wheel steering was turned off, engine died (and so did power steering) etc. But, I’ll ‘fess up, I did it. Amber thought it deserved a good-morning call to let me know that she knows I did it too.

The Case for Owning a Toyota

img_5489The neck of the filler cap on my 2 gallon methanol tank is made of steel. Everything else in the system is either stainless or plastic. So the neck has corroded and little flakes of rust have been falling into the tank and eventually taken off to the nozzle filter. I couldn’t find another filler cap that was the right size made out of plastic or stainless so I decided to paint it, in hopes that the paint would offer a good resistance. Well, two days of use and I see that the paint is already loose and soft.  I called the manufacturer and learned they do make a chrome plated model that might hold up a little better, but they have a minimum order requirement.  So now I need to find a reseller.

img_5493As I was re-installing this cap, I found that the bolts were all buggered up.  I got my tap & die set out to see if I could salvage them.  After lots of trial fits and scratching my head, I figured out that the bolts were metric and the nuts were SAE.  Good grief, some numnut didn’t much care what he was doing when he put this together.  Auto parts stores near me don’t carry a very good selection of stainless fasteners either, but I found some suitable ones at Lowes.

img_5490So why do I have a custom-fit 2 gallon methanol tank?  Because, when I ordered my supercharger kit, I upgraded it a bit so that I could order a smaller pulley to get more boost.  Before I could use the extra boost, I had to deal with the problem of knocking due to the fuel not having a high enough octane rating to resist the extra pressure.  (spraying a mist of alchol and water into the intake air raises the octane rating of the fuel)  Oh, there was also the copious amount of extra fuel needed too, but I had that taken care of already, upgraded injectors and replaced the fuel pump, which of course required upgraded relays and wiring.  So now I have an issue with belt squeel.  It sounds like one of my idler pulleys is going out, again.  (replaced both of them once already)  I don’t think people who drive Toyota Camerys have these type of problems.  These are self-created problems.  I actually like these problems, except that I don’t have enough time or money to keep up with them!

Quadzilla has been pretty neglected this year.  All the time I’ve spent out of town and my vegetable garden projects have really taken away from the autos.  To relolve my belt squeel problem, I ordered a new idler pulley, and while I was on the phone, I went ahead and had Procharger send me a 3.4″ drive pulley too, which might get me up to around 12 or 13 psi of boost.  Tech support says anything smaller than that will require me going to an 8rib setup, which is about $1000 to get new pulleys for everything that belt goes around.  I need to go ahead and switch to a speed density tune, since the MAF is out or range at the upper end already.  Oh, and my rear diff or rear bearings are going out too…
