Rebulding Tranny. Best Flywheel/Clutch For MY Car

[Joey5.0]

My stock T5 is goin out. I will be getting it re-built and i wanna do an aluminum flywheel, and a clutch at the same time. I have plans for a H/C/I soon so i want a strong combo but dont wanna spend to much....What do you guys recomend? And what ounce flywheel do i get 28 or 50?

Thanks!

Fidanza aluminum. They come with 28 and 50oz weights so if you ever build a stroker or something you can reuse it with the 28 or 0 balance.

As for a clutch for a T5, you need nothing more than a FMS HD or a king cobra. My preference is the HD.

Which weight do i need for my car?

And which clutch is the FMS HD?

 

[Grn92LX]

Stock 302 = 50oz.

FMS HD = Ford motorsport heavy duty. Same disk as a king cobra but the HD pressure plate is a little better. The pedal pressure is a little heavier too but not much. I daily drove a HD clutch for over 50k miles, it was fine.

I always thought the King Cobra clutch had the same holding power as the HD, just the King Cobra had a lighter pedal feel.

One thing I never understood was the different weights for the flywheel. So do people run the heavier flywheels on the smaller cubic inch cars to get the rotational mass through the drivetrain?

Aluminum flywheel pros & cons.

Heavy car = heavy flywheel. The flywheel stores rotational energy to get your lead sled off the line without bogging. Use a heavy flywheel when all your power is in the upper RPM range and you want some kick when you dump the clutch at part throttle. Best choice for a stock or slightly modded engine.

Lightweight car = lightweight flywheel. Excellent idea for a car with a stripped out interior and lightened using all the tricks. Keep in mind that when you dump the clutch, the RPM's will drop if you don't have lots of power to keep them up. Lightweight flywheels may bog off the line, but are great once you get rolling. They are the best for road race type applications where the engine is constantly running up & down the RPM range. . Less rotational mass means the engine will accelerate and decelerate quicker.

use a 50oz flywheel

no difference between the HD and king cobra performance wise, only difference is less pedal effort with the kc. If you're under 300hp, the king cobra is a damned good clutch for the money. WOrth considering is a ram or centerforce, though that starts to get into more money.

don't waste your time and money on that alum flywheel, even with h/c/i you won't need it. Stick with stock or billet steel.

jrichker is dead on. The change isn't large, and your money would probably be better spent elsewhere.

My car is stripped somewhat. Rear seat, A/c, jack, tire, etc. But the car is Mostly stock......BBK Intake, BBK Pulleys, catback, shifter, wires, fpr, Alimunm DS.

I just figured while the trannys out, put in a Flywheel. My plans down the road are an HCI, then maybe a Dartblock and hellions turbo kit.

So im gonna order the KC Clutch, and should i keep the stock Flywheel?

 

[FastDriver]

You can, but have it surfaced.

stock flywheel and a king cobra works great!

I ran my KC for around 6 months b4 i pulled my engine, the clutch looked hardly used at all. I put it back in. The clutch is super stronger, my t5 will blow b4 the clutch gives out. always grabbed and never has slipped ever, and has went throught numerous 4k lauches HOOKING at the track!

GOOD CLUTCH YEP!

If nothing else is wrong with your flywheel just get it resurfaced. The lighter flywheel will be easier on the new trans, because it won't hit as hard. Don't go with a heavy clutch, it will kill that trans, another vote for the KC clutch series. What kind of rebuild for the T5? A stock rebuild will only yield another broken tranny.

I really like my King Cobra Clutch, and I had my Stock 115K Mile Flywheel resurfaced.

 

[1988WHTGT]

I have about 40k miles on my King Cobra and stock resurfaced flywheel...works great....took multiple 4k lanuches on M/T DRs....My WC T5 just broke last month, so the clutch outlived the 3 year old WC T5 that I bought 3 years ago, ha

Im Not going with a stock re-build. Gonna have it built like a t5-z.

What are the pros and cons of the lighter flywheel with my combo?

 

[Blk91stang]

Not sure but I'll also jump on the King Cobra bandwagon. Mine survived 405rwhp and multiple launches on slicks! Still looks brand new!

Read my prior post over again and think about what I said...

 

[Joey5.0]

I think im just gonna keep the stocker....

Another Question, do i get Equal length shorty headers, and Un-equal to fit a bbk Offroad H-pipe?

 

[Foxfan88]

t5s are tough gearboxes, but are brittle no matter how built they are. I have a 2.95 Z spec gear set in my car. yes it alot stronger than a stock t5 but its not like i can bang gears all over, it will still bite you in the ass if you abuse it.

A t5 is strong no doubt and is a killer 5 speed tranny for what our cars are, cheap and are fairly durable. The quality of the t5 isnt the problem, its how you drive it. If you drive NORMAL lol and make the occasional track trip, and maybe a little goosing and fun around town. It should last a while. If you go around speed shifting and dumping the clutch and hot rodding alot, it will wear faster.

 

[v8only]

good post.

speed shifting isn't so bad. My buddy did it 2-3 seasons behind a low 12 second notch before breaking his t5, but he NEVER powershifted, that's the key, a t5 can be a great durable transmission if you don't abuse it.
