Temp check, serpentine belt upgrade

Looks sick, are those the rear brake rotors ? What kind of Ferrari is that ? Ive got an 89 328 with AC that works, is there a better upgrade that I can do that would improve the AC as far as belts and pulleys go. I have a brand new fuse board and a new alternator as well , I was just curious, if so I would buy them and have the local F dealership do the work, since they have to swap out the test pipe, smog it, and then have them change the oil.

Thank you Sir !

If I may ask, whats the cost of that insane looking motor ? , and whats the Crankshaft HP ?? Im dying to know,

G

 

Low 6 figures !! Wow, I would have ventured a 50,000 cost at most, boy was I off !!! lol

Thank you Sir.

I’d like some stupid fun

 

When the gods want to punish us they grant our wishes.

Personally, I think the sweet spot in closer to 450-500hp. 1st gear gets pretty worthless but the rest are nice IMO. I think the key is making sure the torque curve is relatively smooth, and if that's true it will behave just fine on the street.... provided the driver behaves fine too . Yes the chassis is a bit spongy but as long as both the engine and driver are smooth in their actions its quite manageable even at very high hp, mine is a sweetheart as long as I don't kick it.

But back to belts, how many amp alternator are you driving? Mine had the poly belts originally and they were awful with even the stock 85A....it would squeal on startup and I had maybe 5 seconds to shut it down before the belt was melted. Absolutely a horrible setup that I trapped myself with on the QV engine by adding the blower in front of it leaving no room. I have a 4 rib now on the V12 and that seems quite good even with manual adjustment it's been fine so far and a HUGE improvement.

 

How many AMPS is the new alternator?
The car does not run off the battery but does the alternator?
Strange one

 

The battery should only be for starting. If the alternator is not large enough to power all the systems in normal use then the battery will discharge and the car will die or will not restart. Add an ecu (5A), 8 injectors (8×1A=8A), 8 hot coils (8x5A=40A), high pressure/flow fuel pump(20A), high flow radiator fan 25A) and the stock 85A alternator I'd more than all used up. Most newer cars are 120-150A for a reason.

At low power around town mine seems OK with 85A, but I'm sure on a high power run it would be less happy

 

Which is more?
Battery = 880 CC Amps
Alternator = 150 dynamic Amps

I politely disagree with your perspective. The Battery is the center of your electrical and teh alternator should only be to top off. The car should never run on the alternator solo

 

Then why bother to have an alternator at all

I'll give you a sort of though.

The battery is a storage device. It provides the energy to get the system started and also stabilizes the system by absorbing peaks and filling valleys...the bigger the battery the smoother system voltage can be. It's important.

The alternator is converting power from the engine to electrical power needed by the auxiliary systems.

The battery voltage is about 12.2-12.5V but in normal operation the system voltage will measure about 14V-14.5V. Anytime the system voltage is above that 12.2-12.5 value the battery is charging, or drawing power from the system not providing power to the system, which means the alternator and not the battery is powering the system.

On my car I log voltage and other than during cranking I've not seen it below 14.2 so the stock 85A alternator SEEMS ok....but I've not run lights and wiper and cabin fans yet or really. Fingers crossed it continues to be OK.

Back of theead point, the real issue I've had in the past been the nearly worthless polybelts, but the serpentseems to have solved that

 

I do disagree on one point. While I do think poly belts were a bad choice, from the start of their use to the end and spending years in 2 of the worlds largest dealer service departments I have never once seen a belt failure that was not caused by either too loose a belt or a belt driven component failure. People failed regularly to tension them properly. They are not tensioned nor were they ever supposed to be tensioned like a conventional belt.

 

Fair enough. For sure the 3 or 4 catastrophic belt failures I had over like 7 years and 15k miles were all tension related so worthless is maybe not accurate. High maintenance and subject to catastrophic failure is maybe more accurate. I've driven a lot of real junk over the last 40+years but 100% of the alyernator belt failures I've experienced were on the 308 polybelts and that is comparing something not less than 500k miles and probably closer 1million total miles on rubber belts to 15k miles on poly belts....so for me, I'm glad to be rid of them and be back to not worrying check belt tension everywhere month.

 

I never recheck tension, never. Do it once, do it right. Your history of trouble leads to a single conclusion. I have had far too many clients with 6 figure mileage with zero belt failures to think differently.

 

No one is suggesting otherwise. There is no question the stock belt drive system was at a practical limit.

 

Well I had been saying for many years Ferrari needed to adopt a serpentine system. Since the very beginning their ancillary drive systems were at best Victorian.

Except possibly the 400-412 belt drive which without doubt were Rube Goldberg inspired.

 

Yes, I will never own another one for any reason

Edit...i basically never drove the car stock. the first thing I did was rebuild the engine and add a blower and efi, I wonder if the extra load was just too much? Either way, hated that belt setup

 

I get why they did it. The polybelt runs higher tension but is lower friction material on smaller pulleys so there is both a weight and hp savings compared to standard rubber v belts.

It was right about the time the serpentine belts arrived but the poly belts on paper offered the same advantages but could be dropped right in place of the old v belts with almost no redesign work so win-win. Sadly they suck though.
