Tranny is the biggest concern I have (after tune/FRP, etc being safe).  I guess there's not an aftermarket rebuild or "beef up" kit yet.

With  the tranny... you can start to tell when it is having issues... When you bend a rod or fry a piston... it happens instantly.

If you read  Ford TSB 10-2-6 (AFTERMARKET POWERTRAIN CONTROL MODULE CALIBRATION, NON-FACTORY MODIFICATION OR AFTERMARKET COMPONENTS) Written 1-28-2010 ( actually the day I bought my Flex...) You will see what can happen to your engine if you don't treat it right.  Also shows what Ford is looking for as to aftermarket tuning and accessories.

If Santa is bringing me presents I want an Audi RS6 wagon from Europe., new dually crew cab diesel pickup, and all the current performance parts for my sho.

Thanks Bob.  I agree.... and I have read it.  If you want to dance you have to be ready to pay the band I guess. LOL

For now i just want the bolt ons with meth and a solid tune. Once upgrades come out for the tranny and such i'll get more power but trying to keep it alive without the aftermarket is expensive.
I've broken 9 or 10 transmissions....so i certainly know about paying to play lol.

Tranny is fairly strong as evidenced by 4 DR... However, it's hard to get the power to the road with the rear only handling about 150 HP & Torque.  If you watch your vehicle at the strip, you will see the rear never really spins. If there is too much difference in speed between front and rear wheels.. ECM says NO WAY... and you bog for a few tenths.  Been there - done that!

I've had it shut off power from this for a period of time. At least i believe that is what you are referring too.

Interesting thought you guys.  I don't need warp speed... but I figure stock is about 290-300 WHP.  Useability is limited by the factors Bob observes. Still, as noted, 4DR hasn't had tranny problems going to 600WHP.  All I want is 400 or so so I my DD is a DR.... Daily Rocket.  Everyone enjoys being at the next stop light while others are still back there.  I think the 100WHP addition should be safe.

So... I'm asking Santa for 100 WHP!

EB and ToE... or anyone.  Given the situation with rear end/trans protection what do you think is the safe limit of useable WHP in these vehicles. TIA

A fairly good amount of SHO users have ran it at the 400+/- area without issues. The problem is just getting it too hook. Like EB said if you spin too hard it will shut off the power on you.
So long as you get traction everything should run smooth or at least get ENOUGH traction lol.
My trans blowing days are from former rides just in case my post has worried anyone.
