Folks:

Just completed my Turbo 3.4 L DOHC 4T80E with Paddle Shifters and Power Steering! Photos are here: http://www.fieroswest.org/LatestProjectsatWestCoastFiero.html

Build thread to follow, later.

Regards,

David

I look forward to reading your build thread!

Car looks awsome, I look forward to reading the build thread.

Now that's making me drool!

What are you using for a P.S. pump?

Not wanting to start the usual discussion on this topic, just curious, but is that emmissions legal in CA (I see that's where your at is why I ask).

Paddle shifter - very cool - I wish I had thought of that!

Have you been able to get it on a dyno yet?

I wann aknow more about that paddle shifting setup.

Folks:

Have not yet had a chance to dyno it, but maybe soon after some small things are refined.

As to the paddle shifter, it is a kick: the ingredients are a 4T80, 4T60E, or 4T65E transmission, a PCS controller ( http://www.powertraincontrolsolutions.com/ ), and a Twist machines paddle shifter ( http://www.twistmachine.com/ ), and finally a new steering wheel (probably). The sites have all the details.

This makes me want to toss the Isuzu idea and go with paddle shifters. The only problem is how much the dang transmission weighs!

What about the new 6sp auto GM has to for the G6 and the Aura. Isn't the 3.6 caddy a 60 degree v6? Now that would be awesome with proper paddle shifters instead of the silly TAPShift layout.

Folks:

Yep! The tranny is heavy, but bullet proof.

The Power Steering pump is a new 1993 lumina pump mounted in thr stock location.

David

There's a few Cadillac engines. I'm talking about the 4.6l 32-valve quad cam V8, also known as a Northstar. If the transmission your talking about happens to have a similar bellhousing pattern, then maybe I could conjure up a paddle shift 6-speed. Gas mileage and high top speed, the best of both worlds! Thanks for the info.

Thanks, David

By the way, while you are there, please take alook at the rest of our site, which is under construction.

what autos where or are six speed. That paddle shifting idea has me bought but I dont want to paddle through only three or four gears.

I saw the car at west fest, I think it is the same color blue as mine. But I don't know about useing gas injection as an intercooler. Care to expand on that?

misting gas not only has an exponentially greater heat transfer co-efficient than a simple intercooler, but it also functions as a way to perform fuel management when properly equiped with the correct electronics - besides, do you care to explain to me where in god's name you would mount an intercooler on a fiero THAT ACTUALLY WORKED?

Great project! A very nice machine indeed. I have one of those in the works myself. BTW yours is the TDC. GM changed the name to DOHC with the second generation so they wouldn't have to qualify which engine they were referring to when they were having discussions. So TDC <= '95 & DOHC >= '96.

What is your compressor putting out now and what do you plan to run when done. After you get it all tuned up and Dynoed, let us know how you did.

Have fun with that one.

Same concept as alcohol injection. Just takes advantage of the latent heat of vaporization of gasoline, which isn't quite as good as alcohol but it does make a difference.

quote Originally posted by Chicken McNizzle: where in god's name you would mount an intercooler on a fiero THAT ACTUALLY WORKED?

Run the exhaust out the back and put the intercooler in front of the cradle. It has been done and does work.

I can't find anyone who has ever used gas injection before. Alcohol also raises the octane rating just adding more gas does not. In my opinion it seems very dangerous adding gas that early in the system. I think that setup will burn the car to the ground. Just my opinion. If it works you may be the first person to figure it out since the invention of auxiliary injection.

Chris West and his crew use that alot. I can think of three 3.4 dohc turbo cars that came from there with additional injectors for fuel and intercooling in their intake stream.

Back in the day.... They had pressurized carburation and vacuum carb to turbo systems. With the pressurized systems the carbs were pumped up to 10 or 15 lbs boost. With the vacuum systems, the fuel/air charge was run through the compressor and then pressurized. This should put into perspective. Injecting fuel at that point is no different then having a TBI setup but of course it must be metered to optimize the power output of the engine.

Water to air intercoolers with the radiator installed in the front work just fine on L67 swaps.

definatly need a build thread for this car.

Chris West and crew have been running this setup in various cars for at least a decade without ever blowing it up.

SHEESH!!! Does it really take a SEVEN HUNDRED DOLLAR unit to electronicly flick two switches on & off? (which is what I understand it takes on the 4T80E)
And... the paddle shifter turns with the wheel. So if you're turning the wheel hard you may shift the wrong direction or miss the paddle alltogether...
I still would like to make a paddle shifter (mounted to the collumn) & use the "E" trans in my V8 Formula when I put it together this winter. But who can afford that?

Dude, its a complete transmission management unit. This is a 4T80E with a 3.4 DOHC. They don't belong together. The N* computer that runs the 80E wont run the 3.4 DOHC without extensive modifications that might not even be possible.
The transmission control is fully programmable for automatic mode and manual mode with two different custom tuning setups. Line pressure, shift RPM, shift speed, torque converter lockup speed, etc etc can all be manipulated in the software while the car is running. It doesn't just take the place of a shifter. Automatic mode is still fully functional (and tuned properly to the 3.4 DOHC turbo) until the manual mode switch in the car is activated.

quote And... the paddle shifter turns with the wheel. So if you're turning the wheel hard you may shift the wrong direction or miss the paddle alltogether...

Yeah, I didn't like that much either. It isn't as bad as it sounds once you get used to it, but the paddles really should be column mounted.

You'll probably see more transmission controllers coming to the market in the next year or two. Maybe you'll be able to afford one. PCS charges a premium right now because they're really the only choice at the moment.

Oh OK. I thought it was just for the trans (it *is* called a "transmission controller"). I don't need anything like that. I just need a "controller" that tells the tranny to shift up & down when I hit the paddles. I don't even want it to shift automaticly. I'll also be running a carb & HEI so I won't be needing any engine control shtuff either.
Sheesh if I had tens of thousands to put into one car I'd just get a Ferrari & be done with it... ;^ p

It's been so long since I've had sex, I can't remember who gets tied up.

ryan.hess developed a controller to paddle shift a 4l60e, 4l65e.

Yeah, I think he may even have an improved version coming out. That would be what "Tha Driver" would want to use.

Steven:

Thanks for the excellent explanation of the paddle shifter/controller setup on my car (Steven did a lot of great work on various parts of the car). Also, thanks for the info on the 7th and 8th injectors.

The whole system works quite nicely and it is unique, I think.

The boost is set to 10 lbs and that is probably as high as I will go.

Why would you want to shift gears in a turn at 6,500 RPM? Paddles work fine on the wheel, I think.

Just posted a pick of the turbo, extra injectors, etc at: www.fieroswest.org Click on: New Projects

If I could get PIP to work, I would provide more photos; any suggestions (I get a runtime error; type 13 mismatch).

Regards,

David

so I have to ask, why a 80e? Why not a 4t65e-hd? It would be able to handle the power you are putting out with minimal upgrades, if any with the weight of a fiero, weighs less, and are found everywhere. I can understand if you are breaking trannys with a fully upgraded 65e-hd (which takes a LOT of power, ie 800whp+) and would need a 80e, but I just dont see that happening.

Why a 4T80E?

I guess it is because nobody has done this one and maybe there is a small block Chevy in the wings?

Also, we had it; why not use it?

Regards,

David

Unabashed Bump

bump for fine work!

i want to do the sameeee thing!

lucky for me the paddle shift company is about 30minutes away!
