LS4 / F40 swap - fieroguru (Page 198/216)

Vince, I wouldn't say the wiring issues were fast to find a fix... but hopefully they are behind me now.

I ran EBC yellow stuff pads before and they work awesome, but dusted like crazy. They supposedly have a coefficient of friction of 0.6, but there is a difference in sharing a single coefficient value vs. showing the coefficient performance graph over temperature, as well as ranking all the typical performance criteria of the brake pad so you can make an informed decision.

The HPS pads are probably middle of the road with regards to the Hawk compounds.



Here are the charts and trends for all their compounds.

I chose pads with about 0.51 to 0.52 initial bite, and operating range in the 100 to 800 degree range, the fronts were rated as low dust, but the rears were picked to have a similar coefficient curve as the front. Overall I am very pleased with their stopping power, but less dust would be nice. I might try some coating on the wheels to help keep the dust off or to allow it to rinse off.

Thank you! As always you've got the data at your fingertips and are always transparent with it.

There are a few 'ceramic' wheel coatings out there that might help with the brake dust. One I used in the past which was inexpensive and really good was made by Hybrid Solutions. I have another I haven't tried yet made by Gyeon, it was pricier but says it'll last up to 5 years. When I get that on my wheels I'll let you know how it holds up!

There are of course ceramic coatings that apply over paint and/or powder coat. There's also Cerakote MC5100 which can go on bare aluminum.

Marty and I drove the LS4/F40 Fiero to Bowling Green on Sunday to start the HRPT.

Car ran good with best tank of 25.75 mpg and hoping to improve on it.

Encountered some rain, did 4 laps on the NCM Track in the rain, and hung out with Paul (R Runner). Good first day!

Bowling Green stop was good. 6 Fieros, and I was able to chat with two of the owners.

This one is from Indiana:


This one was from Illinois:


Some pics of my Fiero:


These types of events really let you stress test your swap and find areas for improvement.

We sat in stop and go traffic for a few hours. Coolant temps got up to 202 degrees, which isn't bad, but I might still look at making the water pump pulley smaller. Air intake temps got to 150 degrees, so I need to do more shrouding with the air filter and might insulate the intake tube.

The tank of gas with all the stop and go traffic was about 12 mpg!

Driving to Nashville Super Speedway this morning!

Need to catch up. Nashville Super Speedway and L&N Federal Credit Union Stadium down w/o any significant issues. Also able to track down and chat with the other Fiero owners on the tour.










This is probably my favorite car so far:









Heading to Hebron Ohio in the morning.

If you're coming up I-77, you will be going right past Marietta.....honk when go over the bridge from WV....I'm about a mile from exit 1!


HAGO!

Where's the radiator on the rod above?

That's awesome you ran into some other Fiero owners. Did all of them have engine swaps, or just that one 3800?

And I agree, that "WW2-esque" hot rod is freaking awesome.

Sage - I'd guess the radiator is in the 'trunk' area with push fans, along with the fuel cell. Given how the trunk area has all of those vents, and smaller intake vents on the sides.

All of that metalwork is gorgeous. I'm guessing it's either stainless or they put clear-coat right over the bare metal? It's gotta be LOUD though, even with those long runner pipes, with no enclosed cabin. My head would be rattling after a long drive.

That was my guess as well, particularly after noting the vents on the side and rear...that backend is just great!

HAGO!

Tedd, we came up I-71 from Louisville, so didn't go past Marietta.

As Vince mentioned, the roadster has the radiator mounted in the rear.

Today we road tripped with Joe Doctor and had 5 Fieros parked in a row at the show... but I didn't get a picture. Here is a picture of 4 of the 5. Shawn joined is after this pic.


Shawn was driving this Fiero and was only here for today.



Had a tank of gas today yield 26.7 mpg, which is promising.
