Morning folks,

I have tried searching and couldn't find the answer I'm looking for, so here goes!

What's the maximum power b16a2 drive shafts can reliably transmit, providing all mounts, bushes etc. are good and tight?

P.S. Forum mods please feel free to link me to the correct thread and delete this one!
 
I know this is a bit of a smart arse answer, but the driveshaft itself will transfer any amount of power you like, 1000 hp plus even - if you use very skinny tyres.... i assume you are increasing your power output significantly but for people to answer your question you should also tell them what clutch are you running, what tyres are you running and what is the purpose of the car? Ie Does it get launched down a drag strip every Sunday or is it a daily? I never understood why people rate driveshafts by horsepower? Using slicks and heavy clutch with stock motor can also end up in CV exploding even tho there was no power increase at all!
 
300whp, turbo, long term reliability street application, 270 or more ftlb, exedy stage 2, oem b16 flywheel, mfactory helical lsd, 195,55 15 uniroyal rainsport 2's.

Why would I run skinny ass tyres when i want to put more power down?

By drive shaft I was including the cv joints, hub splines and gearbox splines. The driveshaft one might say!?

I understand the load on the shaft will determine how much torque the shaft/cv can take.
 
I run the £33 each J&R shafts on eBay, 357hp b18c4 with torque that sheared a innovative engine mount. Shafts are fine after 5k kilometres.
 
I only used skinny ass tyres to make a point - driveshafts are only one component of the drivetrain and their longevity very much depends on the power output as well as a whole bunch of other factors, for example tyres. I have zero experience with turbo'd Hondas so I can't answer your question, but others now at least should have enough information to share their experience. I also use j&r shafts, the quality can be a little hit and miss but for the money they are very hard to beat. They are imho no worse than Yonaka and similar stuff just much much cheaper. If you have the cash DSS shafts might be the answer I guess. Personally I only worry about stuff when it brakes :D
 
Its transmitted torque thats the issue, so slicks would be more strain than high engine power.

The cvs etc are going to be much weaker when the wheel is turned too, ie hairpin corner exit compared to drag use.
 
270ftlbs and only 300whp?
Mines at 230ftlbs and that makes 350hp
 
Throwing figures out there to get answers lol. All I know for certain is I'm putting a gt2860rs .86 and trying to keep long term repliability. I doubt ill even run enough boost for 300whp as I would say that's "close to the limit" of stock reliable longevity and more than likely unnecessary for a FWD street car
 
To answer the original question I feel the stock shafts will be fine in your situation.
Im still on stock shafts and mines a track car with a plate LSD in so you'd expect it to be alittle harder on them
