Hey Doward, thanks..........

I was reviewing This , and THIS .

I belive way back we also discussed routing. But you have reinspired me. Sunday, at the T/A Nats here I scored a turbo setup from hte 301 Turbo T/As. SHould be good for about 4-6 psi stock. I belive safer thatn the f*rd one I had before.

Doing some research now on what got hooked up to where.maybe a Third Gen turbo 3.4 could be in the works.....

Id like to see someone get one cheap enough and explore making it belt driven.

as in remove the exhaust portion & hook up a pulley to it? I think I've seen a pic of one, or maybe they just hooked up an electric motor that took about 5 million amps to run.

Anywho, would the impeller need to be changed if belt driven & not exhaust driven? I don't think it would be blae to spin fast enough for any real performance, but then, I'm really no one to talk .

if the turbocharger were to be belt driven, then it wouldnt be called a turbo, it would be called a supercharger. The whole point to a turbo is for it to be driven by the exhaust.

would not work well on a turbo.

Turbo bearings are not made to pull pulled on like a belt would do, and would quickly wear out the bearings.

It would work, but not long enough to make it usefull.

I would still try it. screw the bearings. A used almost free turbo would last plenty long enough to work it out. I wouldn't do anything but stick it on and go. stay unde 5psi and its just like a well built ram air system going 150mph.

The computer will deal wit hit.

What is different about that chip n a oem n a "super" chip???

-------------

Just because you are told cats will land on their feet. you still just gotta toss one up in the air to find out once in a while.
The only problem in invotation, is the lack of trying.

increases the amount of fuel the injectors will fire so that when under boost, you dont go lean and melt your pistons.

How does the chip know the car is under boost or not??? What if the turbo went/broke, would you be running around rich all the time???

or that chip just compenstats more than an oem chip when it see lots of air flow???

its a chip just compenstats more than an oem chip when it see lots of air flow.

the best option would be to either get a piggyback computer, or a tottally new computer that has a boost sensor and an airflow sensor, they are the most accurate and most failsafe.

actually i did alot more the any piggyback everr could. i increased the dynamic range of the sensor. setup the timing values for boost.i fixee the problem with being overly rich using 19-22pph injectors. in short i fixed the problems you would have. im just offering copys. if you dont want one i dont give to ****s either way. just as an FYI what you think im making $1,000,000 on a bunch of chips ? lol.

Do you have any other chips???
somthing like the super chips???

Id be interested in one.

Be great if a chip could change the computer so I can dump the EGR system, I also run no smog pump or cat but found it runs a tad better with the egr hooked up with my oem chip.

It might even fix my car's problem, but I have a hook up w/an 86 that I'm gonna swap sensors, maf, map & ecms & a 12 pak to see if it works better than what I have. If not, I might be needing an address

well, the stock ECM doesnt have a pressure sensor, so it can never be as good as a piggyback with a pressure sensor.

maf cars don't need a pressure sender. the maf directly measures the amount of air coming in. That's how Funstick and I are able to operate under boost, with no problems.

The limit is the 255 g/s of the maf/ecm. Seeing as how most 3.1s pull about 130 g/s, that's about 14psi of boost left in the maf - not counting tuning WOT P/E mode for say... a spike of 20psi.

All entirely possible. No 'piggyback' (read - fudging the numbers) needed. The stock ecu is perfectly capable.
