Real tech discussion on design, fabrication, testing, development of custom or adapted parts for Pontiac Fieros. Not questions about the power a CAI will give.
He will be testing the strength of the gears themselves. At my planned power levels I am already running the risk of killing my 3rd gear. Luckily I can buy an OS Gilken gearset good for 800whp in my stock case. This is a low torque 2.6L engine, so I imagine a 3.4dohc at the same power levels will have more torque and more driveline stress. The GTR transmission is huge and beefy compared to the getrag in a fiero.
He will also be testing the strength of the 3.4 block.
I hope it holds together, if it does there is hope for a manual fiero to get into the 10s. Imagine that, a fun to drive manual fiero that's also fast. :blah5:
Yes, axles go POP, just hope it doesnt happen at freeway speeds. That
will seriously damage the frame rails and cradel at least.
Trust me Ill keep you all updated on new Getrag failures. i didnt get a
chance to start on the new brace for the diff. But fuel rails are
done. :thumbleft:
Billet L brackets
inj at 20* angle
So dose anyone know for sure what this trans is for? it has the Quad 4
starter config.
Fyi- I never "lanuch" may ride the clutch a little more but thats it,
Im scared of shock loading....
Unknown. Unfortunately, if you can't find what year car it was offered in, you won't know without counting turns with it in each gear... or you could just count them when you pull it apart for the case change. Look at the diff too; should be obvious if its the new style or not. They changed in 89 or 90.
Since you are spending a lot of time and money on this setup it might be worth getting some custom axels made.
It would be interesting for you to run a non reinforced 282 and see if it fails on a full power run. I imagine 95% of the failures are SBC guys dropping the clutch with a 30# flywheel.
Yes, its a W Body inter. shaft, I used a stock drivers mans axles and
stock passenger w/auto just changed the end and bearing from a stock
wbody axle.
I have mocked up some axle hoops, 4... one on either end of the axle,
much smaller and no need to compensate for much travel.
Levi, Thats a very interesting point ( unbraced ) custom axles are most
likely gonna happen. And A totally custom trans, case and internals. Ive
got over 6k in the engine, think that warrents a similar amount in the
driveline. But just seeing what will happen and how strong it really is with
some external help.
OH you're using the enclosed half shaft? I wonder how much that helps with the structural integrity of the case on that side when you have a good bracket holding the other end. I would think it should add a LOT of stiffness. Trying to crush a tube flat in longitudinal compression is pretty tough!
Exactly, the the mount that comes off to support the tube also mounts to
the cradel with another motor mount. And its made of 3/8's 316 stainless
plate and bar stock.
I pretty sure I put up a pic of it....
