This is an Eaton M62 on a Lotus Elise 1.8L (with intercooler)...I guess it CAN be done...WOOHOO! lol.

 

Yeah, I mean, if someone wants to make an adapter for a ford Eaton M62, by all means.

I know it has been done before and that lotus setup looks awesome! It's even intercooled. The boost from my proposal could go into an intercooler as well and then into the stock intake setup.

Can't wait to get my donor blower to start fabricating!

 

i have a huge gut feeling that it really won't fit the xA

oh well

prove me wrong

 

As small as these are, they are pretty versatile as far as where to mount it. Blitz has one for the xA, so this one shouldn't have a problem. Of course, you wouldn't be able to mount it where the drawings are above, but that was already stated as an example of what he wants to do and actual mounting locations may be different.

 

Very true, I can put it at an angle, or wherever it would fit. As said I HAVE an xA, but it is at the dealer for the 5th time due to the charchol canister (no we do not top off) so when we get it back monday I'll take some measurements.

I know for 100% it will fit in an xB.

 

There seems to be some questions as to why I am using an M62 as to say an M45 for smaller motors.

1.) Easy to find. The config is all flat with no crazy adapters and such for intakes. Most M45's also have an electric clutch to activate the pulley or not. An M62 from a 3800 motor uses a vacume system to bypass boost. As such, you will not need to dial in a 'kick in now' setting and a specific throttle. It will always work when you get on the gas and the engine load requires it. As such it is a gradual 'on' switch and will slowly start to build more boost the harder you push the gas.

2.) M62's are positive displacement blowers. As such, if I used an M45, I would have to spin it faster than I would an M62 to get the same volume of air. The number after the 'M' indicates how much air it moves per rotor spin. An M45 moves .45cu feet of air per rotation. An m62 moves .62cu feet of air per rotation. As such, the M62 would be spun at a slower RPM than the M45 to achieve the same amount of airflow. Yes it is a larger blower thus will require more power from the engine to turn it, but the boost coming out of the outlet should be of much lower temperature preventing knock and in turn making a bit more power.

A giant turbo requires a certain amount of exhaust volume to spin fast enough to give you X amount of boost. Positive displacement superchargers give you a fixed amount of air per rotation, as such, you simply have to get the pulley ratios right to spin it at the proper speed per RPM to achieve the boost one is looking for. This can easily be calculated for target PSI settings. Also, we have modular pulley setups for these blowers, you can always put a smaller pulley on it for more boost. These pulleys are about $60 a piece and each one would give about 2 more PSI. As I don't intend to change the injectors at this point or mess with the ECU, I will stay around 6 or under while testing.

 

well sounds like you do in fact know what your talking about lol, i sure dont have a clue...but this is interesting.

this reminds me of computers, you can go to dell or gateway or whatever and buy one pre-made on an assembly line for a chunk of cash (brande tc's and sc's) ..or you can buy the parts and build your own computer if you know how (this example he's fabricating his own setup)

interesting!

 

i'm just thinking due to the hood clearance being lower on the car

 

Hehe, I just built my own computer last week. All the parts were bought from newegg .

*hugs comp*

 

How do you intend to handle fuel management? 6psi though a small amount will still require something.

Emanage is probably the least expensive, but im pretty sure greddy is not making thier plugnplay for xB available anytime soon.

 

I have a few ideas for fuel that I will try out. I also want to impliment a fuel pressure regulater as fuel pressure should climb at least 1psi per psi of boost. I have a few contacts in the 3800 world that may be able to help us out.

We have a tool that allows us to manipulate the signal from the MAF to adjust fuel for larger injectors. I have to read up on the 1NZ-FE maf setup first though but the principal should be the same. Basically if you install a larger injector you want it to squirt for a shorter period of time to deliver the same volume of fuel. What our tool does is take the input from the maf, and lower it a set amount and send that signal to the ECU. This is done in real time with a high speed processor.

An example would be the Maf sees XXXX signal for Wide Open Throttle with 6PSI, it would command the stock injectors to go nuts and spray a ton of fuel, this doesn't work with changing the injectors to larger ones. So the tool would take XXXX signal and lower it a set %age and send THAT signal to the ECU basically saying there is less air *than there actually is* so squirt less. In return, the larger injectors squirt the proper amount and everything is happy.

This is VERY useful for idle and low RPM driving as you can subtract "air" that the MAF sees and have the larger injectors shoot a shorter pulse.

We can run just about any injector on a Series 2 3800 and configure it with this tool. The tool is $130. I am going to try and have one made for the xB.

This may seem fuzzy. It will all come together soon I'll get more details if/when I have the tool to do so.

I am also going to get my scanner program up and running to find out just how much this ECU 'learns' compared to what everyone is saying. ECU's have set parameters as to how far this way and that way they can change a value before they run out of room and set a fault. Microprocessor controled spoofs such as the one I discussed may be a good way to get around it seeing as we can't actually change the code. I have to read up on this 'emanage' thing, but it sounds more expensive than what can be done with direct electronics.

 

Is there a way to impliment megasquirt into this kit? I think that may be best. Then you will get the most performance out of your kit. If you need anything machined seriously shoot me an e-mail and I'll get you hooked up. I would really love to see this come together.

 

I was reading on the TRD SC for the Matrix. The matrix has the 'no return' fuel system similar, if not the same as an xB. With their SC, you have to buy an extra installation kit and it includes a piggyback ECU with an extra injector. This may be something to look into. It obviously needs the extra fuel if TRD is adding injectors. I wish I could find out more about it and the Matrix fuel system/ECU compared to the Scion.

 

I may change the fuel system all together, but if I can get this device I was telling you all about, I won't need to (in theory) as I can run larger injectors. I need to find out specs such as the stock fuel pressure PSI, how much the stock fuel pump can flow, etc.

When I start getting into the nitty gritty I will be researching more about this. At this time I just wanted to post my idea. I'll have more pics when the mock up blower comes later next week.

I would like to avoid a fifth injector at all costs, it isn't the right way to do things, nor do I want a piggyback ECU unit.. I would rather spoof only that which needs spoofing.

 

good luck bro i hope it works

 

I got a "piggyback" that does ecactly what your "spoofer" does...
It intercepts the MAF signal from the sensor, and sends whatever adjustment you make as though it were the original signal. It also monitors throttle position, injector duty, rpm, and Knock, also it datalogs. It is quite pricey but super easy to use, and it only spoofs that wich needs spoofing.
I just need to get an obdii scanner, ugh my wallet is giving me a headache...

 

Xbilly, what is it that you use currently?

 

Its the TurboXS dtec-fc, the one that uses a Gameboy advance as an interface and gauge. I just finished hooking it up today (my car is still alive, YAY!) I also have a wideband from TXS wired up but I still need to weld in the bung for the sensor. People wanna charge me upwards of $70-$200 to weld in the bung, so im gonna do it myself.
Once I have the wideband up and running I will install my blitz kit and start tuning
If I learn anything without destroying my car , i'll share with you.

 

how much did you pay for the wideband?

 

Interesting thread...
