Still in the same ballpark. The bill of materials is still evolving.

Re: '88 wheel bearing and hub upgrades

6061. I might switch to 7075 if I make another set to just to avoid having to use a steel insert for the LBJ. THATS HAWT! maybe I missed it, how do they compare to stock weight wise? Comparing the knuckle+steering arm+hub+LBJ the gain is 4 lbs per corner. The brakes obviously add weight as well but ...

Re: '88 wheel bearing and hub upgrades

Got the left side mounted today and tested the articulation. Found some minor interference to the lower control arm at full droop plus left steering with high caster angles, but that's easily fixable with some sanding, and I'll add a relief in the CAD. The real issue is my lower ball joint is sunk t...

Re: Will's Bug Out Rig: Duramax Van

Do you know anyone with an Allison in a working vehicle that you could install a CAN logger in for a bit? Just need a few conditions.. stopped, engine off. Start engine. Idle. Put in drive and stand on brake for a few seconds. Drive off at steady slow speed first gear. Then a gradual acceleration up...

Re: '88 wheel bearing and hub upgrades

Things are getting real... The first prototype billet uprights for the 88 Fiero have arrived. Feature highlights: Massive wheel bearing strength upgrade as well as stronger ball joints. Inexpensive 4 pot Brembos (Camaro6, C7, and C8 Corvette), 5x120 bolt pattern for wheels (BMW fitment with hubcentr...

Re: wet sump engine oil control, a thread.

My oil pressure drops during long left sweepers. 200tw tires, front splitter and a smallish rear wing. I overfill the pan on my LQ1 by about a quart. Oil pan is stock. Stock windage tray.

I didn't know it was happening until I reviewed some in-car video. Android tablet datalogger showing about 1.1G.

Re: SN95 Mustang Knuckles on front of Fiero?

Something like this might work but you need to make a new lower ball joint boss and steering arm. Also the front sway bar end link on the 88 Fiero will interfere with the steering arm. After you solve those issues will the geometry be right? They aren't cheap parts to begin with so what are you savi...

SN95 has MacPherson strut front suspension. They are nothing like the Fiero front. Are you thinking of the Mustang II?

Re: progress on the banshee...

If you use the C5/C6 wheel bearing geometry, there is a Chrysler application bearing with the 4.5" pattern that bolts right on and even takes the same axle: 513089 (93-04 Intrepid). Is there an outer CV that works with Fiero axles? GM used 27 splines on the large pattern A-bodies and 33 spline...

Re: progress on the banshee...

The Timkens, like all other aftermarket wheel bearings for the Fiero, are junk. In track use they have been known to break off at the flange. On the street, longevity is poor. Make sure to tighten your axle nuts properly. Loose axle nuts will ruin the bearings very quickly. OEM Fiero bearings are di...

Re: 1988 Fiero track car

The Cavalier bearings add 2mm offset to the hub so you may need to face your uprights or make some changes to your brake brackets. The stock sliding calipers can accommodate the change but those fixed mount Porsche calipers probably won't.

Re: NA 3900 Build

I recommend running the sensor wire alongside the alternator cable back to the battery. Very little current flows through the sensor wire, so it will have an accurate read of the voltage at the battery. Lots of current flows through the alternator cable at high charging rates which causes a voltage ...

Re: Group buy: Front Lower Spherical Bearing Shells

I hadn't considered the axial tolerance issue for a monolithic control arm with two bearings. Makes perfect sense. The ones from Afco above are for a single link rear control arm. I suppose you could supply a kit with undersized spacers and a set of shims to align a control arm to a specific subfram...
