He recently installed that, but apparently he's been running 100 octane on his previous dynos and not 93, but no meth still. I've ridden in his car on his old 25 psi s475 build, no meth, just holding on for dear life.

...and 500 ft/lbs of torque as of a few months ago, FD's have pretty weak transmissions and rear ends though. FC's don't tend to have those issues other than the rear subframe mount. But there are several 500+ hp FD's in/around Charlotte, and his is about as reliable as they come considering it gets beat on all through the week. When you more than double the power output that a car was designed for you have to expect to break things, I would still venture to say that's pretty reliable for what you're asking of the car and a 1.3 liter engine.

The car is not designed for 500WHP+. Like you said the transmission and differential are not going to last very long at those levels.

I mean is the trans and rear going to blow at rolling speeds? Seems to me like the stress is a thousands times worse from launching with 500rwhp. Is it common to shred gears at 500rwhp while rolling?
I mean theres quite a few big hp 20b dudes running stock trans just fine. Its beating them up on a strip w solid axles and dual clutch thats blowing out the gears.

first we talked about how much power can you make on 93 reliable. since there is no other thing to talk about. now the drivetrain wont hold 500hp ? well that i agree. but on a roll i dnt think you will break it

500WHP is a lot. The car came stock with 210's or something WHP. you are over double what the stock engine puts down. I am sure some components are overengineered and I am sure some have a lot less margin of safety.
I don't see many 500WHP rx7's running around for 80-100K miles. So is reliable being able to run the car for 10K miles without problems? 20K miles? I would consider such short lifespan to be unreliable.
I do understand that sometimes things can break, but from watching videos and being on this forum, there are few who have gone the distance driving a 500WHP vehicle for a very long period of time enoying it to its fullest at that WHP who doesn't break a lot of crap.
Hell, lots of people break things with mid to high 300WHP.
IMO, if I was dead set on 500WHP and that was that. I would pick up a different vehicle that has 400-500HP from the factory and get it up to 500WHP.

Why not go with like 350WHP and not worry about breaking crap and be able to thrash it.

The car made 440rwhp and 358 torque today at 19-20psi pump/water/meth on the T04S with Ray Wilson tuning. I believe this to be pretty damn good considering the size of the turbo. Highest I've ever seen a T04S is 469rwhp @ 22 PSI so far.
Will post a vid soon.
Thanks for the comments in here guys.
