Peformance Chip for 80

[Terrax]

I had my unichip installed today at a Porsche shop and it pretty much took care of my detonation problems. The most amazing thing besides having a Landcruiser at a Porsche shop is that I met the person who designed the TRD/Kazuma supercharger in the flesh, he happens to be racer and Porsche racing team engineer, he looked under the hood and told me that he design it and sold it to TRD. TRD test drove the prototype cruiser vehicle and said we must have it!! The original design had a intercooler and 7th injector setup which they changed to cut the cost (argggg!!) he mentions that it put out over 400 HP and it cooled the temperature in the chamber by 80 degrees.

Terrax,

I wonder how much boost he was running?
I wonder where he located the 7th injector?
I wonder how much timing he was using?
I wonder if he was using any kind of Unichip?
I wonder if he changed the compression ratio?
I wonder if he reworked the head?
I wonder if you got his name?

I sure as hell got his name since he has lots of info., the 7th injector went in the adapter coming from the manifold (part of the TRD S/C ) TRD changed features of the design unbeknow to him as to why (maybe to make it cost effective to compete with the Safari turbo that was available at the time) the answer to the other question is 6 psi of boost since it was the stock setup.

Terrax,

Thanks - I was just surprised when you mentioned the HP figure. I didn't think you could get that with 6 psi of boost. Also, with the losses from the intercooler/plumbing I wonder what size SC pulley he was running. I wonder what his trigger was for the 7th injector - a certain RPM or a certain amount of boost? The reason I asked about the 7th injector was I am setting up a two stage Methanol/water injection system. The original theory was to inject before the SC so that's what Cdan and I setup for with a one stage setup. I added an intercooler and was concerned about condensing in the intercooler so the theory now with that seems to be to inject after the intercooler. No one seems to know for sure so I will have to test. I am making provisions to do both so I will be covered, but it sounds like he was injecting gas after the SC. I wonder what the nozzle size and angle was? Another thought I had was to inject (gas) in the manifold at the number five or six cylinder to richen those up to help with the HG that seems to go in that area (maybe from them running lean?) CDan came up with a good idea and suggested maybe running larger injectors in those two cylinders instead.
Glad to hear they got you setup. I would probably have gotten tossed for asking that guy so many questions.
Thanks for the info.

You really want to ensure that the fuel going to each cylinder is balanced. That's the big advantage of multiport injection.

Over a year ago I called up TRD tech support and asked if they were working on releasing a 7th injector for the supercharger. The guy asnwered "No, but we might". I'm not holding my breath.

On a different topic, do you think that the supercharger casting that mounts to the side of the head can be welded? I presume that is an aluminum casting. If you cut off the top of that casting, and rotate it 180 degrees and weld it back on, the air outlet tube would now face towards the front of the engine compartment. If you look a picture of the safari turbocharger, you will now see how you could then easily route the tubing to install a intercooler. This is all based on photos I have seen of the supercharger and the safari turbo (I.E. reality may vary).

Great to hear you guys have a shop in your area who can fit and tune the cruiser for a Unichip.

Now your detonation problem is fixed, how is the torque, and power with the unichip fitted?

Given the 95 on injectors flow enough fuel for the safari turbo, I cant see why a 7th injector would be needed, but the unichip has 2 outputs I think as well as the inputs which may be able to be used, if using a pre 95 engine set up with unichip, 95 on should be fine with factory injectors,a nd maybe a wee bit more fuel pressure

The 7th injector could be run with a microfueller, or from boost pressure, and throttle position, and the water/meth injection definately has to go between intercooler and engine, otherwise it will seperate in the intercooler, and end up a puddle in the bottom which will one day run into the engine on a hill.Ideally the injector should be in a high flow area, pushing toward the intake manifold where it has time to mix fully with the air charge.

I would run a pressure container with a hose from boost to it and a one way valve, so when max boost is made it uses the 6psi or what ever to push the meth/water down the hose and through the mist nozzle.

Rich,

I had considered trying to rotate the top of the SC. For me it did not seem feasible especially with dual batteries. Here are a couple of pics showing the route I took. Hope it helps you or others. Using 3" straight through made it a little harder. Thanks to Turbocruiser for going out in the cold a couple of times last winter and taking pics for me of the front of his Safari setup.

I thought that the TRD SC was just a run of the mill Eaton M112 thats really just an age old swedish SC Listrum(sp).

By the way you can get the Eaton M112 for $300 off of EBAY, they come off of a 1999 and higher Ford Lightnings. The electronics and what nots for a LC mights cost $300,000,000,000, but I know where to get the origional TRD chip that no one talks about?

You are right he used the Eaton S/C but the rest of the design, intake, plenum, etc. are his. Basically he designed the S/C kit around the Eaton that he decided would fit and work best for the cruiser.

Was this on the 94 truck? Also, what did they add/subtract to get the detonation to go away. Any dyno results?

Did he used to work for Cameron Concepts. I believe this is the truck that had the first supercharger design on it.

if you look at the performance options, then you can see a picture of the SC.

An Eaton M90 actually........

 

[cruiserdan]

Dang Bill!


That engine bay is getting VERY BUSY>>>>>>>>>

 

[lurker]

Yes sorry the M112 is an upgrade to the puny M90.

That being said and since no one is really supporting any engine upgrades maybe WE should look into building our own SC intakes for M112. They're cheap you know.

Christo,

I don't know if the guy worked for Cameron Concepts, yes it is a 94 truck. I actually had the chip tuned via laptop due to the fact that the wheel adapter was only a 5 lug on the dyno. I'm going back after I come back from vacation to retune it via dyno after he gets a 6 lug adapter which he's fabricating. It's a 2 wheel dyno so we have to disconnect the front driveshaft and lock the center diff lock. Chris (the Unichip tuner)pre-set the specs on the laptop while in the shop, we then got on the freeway and took it up to 75mph with the laptop connected to the chip while driving it and he fined tuned the timing and fuel delivery specs at different rpm 's. It actually worked, the guy installs unichips in Porsche's and is involved in racing so I trust his instincts and it actually worked at getting rid of the detonation. I definetely want it dynoed, I'm going to add a cartech fuel rising rate pressure regulator then we'll dyno it. Stay tuned.

Thanks for the picture Bill. I see you have the intercooler well sorted out.

 

[clownmidget]

Bill, I pm'd you but didn't get any reply... What oil cooler are you using under your intercooler? I'm looking for something very similar as that to fit in that same spot. Let me know what you used when you have time. Thanks.

Mike,

Sorry, I PMed you back but must have done something wrong if you did not get it.
The trans cooler is a Modine Model 1B137 and measures something like 21 X 6 X 2 1/2 inches + fittings. A big caution if you try my setup is it sticks down a couple of inches below the frame rails. I did mine like this since I had made the skid plate lower to hold my water/Methanol tank (will have to make a new one somewhere). The skid plate is now almost redone except for filling in the holes with expanded metal. I have to get it done soon as I have most of the plumbing at the powder coaters and want to give him the skid plates and mounting brackets when I pick up the other stuff on the 8th or 9th.
Here is a pic to show the cooler mounting and lower location if it helps you. Also, notice the extra holes in the frame crossmember for airflow. Before anyone says anything, yes I realized I may have weakened the crossmember and will take care of it.
I will PM you again tomorrow with the other info you wanted.

Bill

[clownmidget]

Bill, thanks a lot. I think I might have a bit more room than you since my intercooler sits a bit higher. Don't know but I'll measure. I've got a M12000 to deal with as well so I'm not sure that cooler is going to go there anyway - running out of obvious places so might have to be creative. Looking forward to hearing how your setup runs.

On a different, but somewhat related note, my new to me '96 came with JET (www.jetchip.com) performance chip. (Sorry, no S/C or Turbo - yet) I looked it up on-line and other than finding out it costs about $400 could not really learn anything about it. Does anyone have experience with this product, good, bad, or indifferent?
