Nice work, I like those tips much better. I can't wait to see this thing in person soon!



Thanks, it was very popular at the Sunday evening cruise in Niagara Falls...



Plan to bring it to the Welland Seaway Mall Cruise this Friday evening as well.

You really appreciate the artistry of exhaust system fabrication once you've tried it yourself! The new tips seem to blend better the all the body mods than the others did. Looks great, can't argue with improvements!

Thanks for the feedback.
This weeks project has been to finish plumbing the A/C lines to new condenser and charge the system.

Took Friday off so after getting the A/C charged my son Andrew and I had time take it to a cruise night at Seaway Mall Welland.



The tuning is better dialed in, as I worked on the carb setup.

Installed richer idle jets I drilled to a Dellorto #58 (size .0225")
After starting with rich (safe) #160's the best Main Jets have been the #150's as the venturi's I'm using are 36mm (times rule of 4 or 4.2)
Unisync guage was used to rebalance airflow on all 8 carbs to "6" on my guage (at idle of 850rpm)

Still experimenting will the timing advance but the latest settings after stabilizing the carb adjustments are:

Mechnical timing 0-400 rpm 10 degrees
Initial timing 1000-3000 rpm 8 degrees
Advance timing 3000-redline rpm 14 degrees

From what I've read online total timing stock for my engine is only 26 degrees and modified should be around 31 degrees.
I'm running 94 Octane and the redline limiter set at 7000 rpm.
Of course I'd like the most timing without detonation.
I think I'm going to need use of a chassis dyno to find the best ratio between the adjustable initial and advance settings.

FYI locals - Fiero2m8 is going to be at the Gateway Niagara cruise Tuesday evening

Good news for Fiero2m8 as I spent over an hour in stop and go traffic on the QEW in 37 degrees C heat without a cooling issue - the minor rad leak is fixed.

Bad news was later in the week when I broke an axle during a hard launch requiring a tow home
With the increased horsepower and the Kevlar clutch/pressure plate setup working well, the new weakest link ended up being a Porsche CV joint on the drivers side of the transaxle.
Turns out the axle was fine but the cage broke inside the CV housing, so I removed the axle and disassembled it in under an hour.
Looks like I am going to need a new one piece boot (guessing 1974 version based on numbers molded into boot as I think the 1975 version was a two piece setup).
I found a boot for the 944 but it is different so I need the 914.
Also need to make sure the splined end of the Porsche axle is stock diameter - this will ensure I get the correct CV for it.
Still not sure if it broke due to excessive torque or if the axle bottomed into the transaxle flange when the suspension compressed.
Since there were a few marks on the end of the axle, I got proactive and shortened the axle approximately 1/4" anyways.
Here are some pictures of the disassembly:

Hi do you have a complete list of parts required for the 88 front and rear hub upgrade. I will have to do this to cope with the extra torque of the v12.

Thanks Carl

t he rear of the car is a custom frame I made using a c5 vet rear suspension cradle mounted to a custom set of frame rails

Hi Carl,

For the front hubs, below is what we used for hub bearings.
It does require some minor machine work to fit them in the 88 spindles.

"After some more R&D we are going to mod Bearing #513009 due to its outer diameter size of 2.79" vs. 88 spindle of 2.74"

Timken or FAG #513009
Cross Ref #7466902 7470539 7470540
Non-Drive (FWD)
REAR w/Disc Brakes
Non-ABS

Fits:
1979-1985 Buick Riviera
1979-1985 Cadillac Eldorado
1980-1985 Cadillac Seville
1979-1981 Oldsmobile Toronado
1982-1985 Oldsmobile Toronado

Good luck with the V12 project!

Stopped by to see Auguste and he has ordered me a boot and cv joint.
Turns out the 914 one didn't fit so we went with a VW bus one that needed slight modification.



Two of the opposing 6 holes were countersunk drilled so I could transfer the locating pins from my old cv housing



I am chalking this part failure up to unknown age of the part - if it breaks again, I will find a way to upgrade to larger flanges and CV's

Reinstalled with new grade 12.9 bolts, cv grease and made my own gaskets with RTV
