How much HP can the stock clutch handle?

I'm about to have my '94 FD up and running and just installed a brand new OEM clutch. What HP can this clutch handle?

My mods are only a street port and intake right now but will add a downpipe very soon. Also, sometime this year I hope I will have catback exhaust, midpipe, PFC, and boost 12 psi.

When do you think I will need to change the clutch? I'm sure it will handle just the street port and intake for now...right?

Thanks matty,

That means I'll have some time before upgrading and it won't be a waste of a brand new clutch.

Not sure of my hp, but have a dp, cat-back, RB intake with K&N, and aluminum flywheel. No slipping for 2 years. I put in a new OEM clutch when I had the flywheel installed.

None.

Clutches hold torque, Not horsepower..

That being said ~250-275 ft/lbs of torque and the stock clutches holding ability will likely be compromised. So that equals a ton of boltons - or a small single!

you are absolutely correct...but 300rwhp in an FD fits into that range of torque. Just keeping it simple.
At 15psi i am making 300ft lbs and the stock clutch is basicallly worthless at this point...i found that out yesterday at the strip.
