long story short, I went out with a buddy and left my keys and car at home. When I got home my car was gone along with my keys & nitrous bottle I had in my room, turns out my ******* brother took it out for a joy ride with his friends. :mad: Any way he came home and the car was ideling high as hell around 3500 rpm's and claiming he didn't use the nitrous. The butter fly plate on my frpp 65 mm t-body has a nice U shape to it now and even after bending back to shape as best I can, I can't get it to idle lower then 1500 rpm. I'm pretty sure I can't go buy a new plate from the dealer and I'm sure as hell not dishing out $200 plus for something I didn't break.

Does anyone know if an explorer 65mm uses the same plate? I'm sure I can find a few in the local bone yards. If not any idea how much it would run to have a machine shop make a new one to fit? :rant:

I'm ready to kill him the car wasn't even on the nitrous tune so I'm suprised he didn't nuke the head gaskets and melt all the plugs.

Personally I woundnt screw around trying to fix the t body. Agravation, time etc. new.
How the F--k did he manage to bend it? backfire? Man I'd be so mad!!!! nuff respect for not being in jail right now.

My guess was he hit the nitrous off idle and it backfired. I had the 150 jets in there from the last time at the track but never got a chance to run it on them. He still claims he didn't spray it but can't account for what happened to the 3lbs of missing nitrous. He knows I weight my bottles too.

I found out Holley sells one Throttle Body Service kit Part # 26-134 but I don't know if it will work with the frpp t-body I'm guessing its just for there's but I sent and e-mail to there tech suport any way. I'm going to the local svt dealer tomorrow to see if they can get me one.

if he bent the plate, I'd be sure to bet on it there was a nitrous backfire... There's absolutely no way in hell that ANYONE can beat on a Mustang and BEND a throttle body plate... SOMETHING else came into play that actually had enough force/pressure from within the engine/intake path to bend one of those plates! Damn!

I'd make him pay for the damage - but at the same time, you better pull some plugs and check for any other damage...

Take the throttle body off the car. Remove the butterfly plate. Once you have the plate removed, if you have access to a vice, put the plate into the vice with (2) pieces of wood on either side of the plate (make a sandwhich - wood-plate-wood). Then once you have the plate/wood set up in the vice, keep tightening the vice, so what will happen is the vice will flatten the plate out evenly - hopefully back to the original shape. It may not come out perfect as it was from the factory - BUT - it will be more evenly bent/flattened out and may work better until you can get a replacement throttle body or plate.

good luck!

All ready done, used a buddies press and two peices of 3/4 stock scrap aluminum to sandwich it . Just need to pick up some new gaskets from winner ford in the morning . Its back on but won't idle too well, its about 500 rpm and trying to stall. I have to play with the set screw some more. I went threw the plugs and everything else, first stumbled apon the t-body whent everything else didn't pan out.

As for making him pay lol He still owes me 200 from a party last new years.

actually, if you go that route with bending it back in place, make sure you put some thread locker on the butterfly bolts. I know 2 guys who lost one of the bolts down the intake and did some damage. I had the main shaft(that the bolts go into), break on my bbk throttle body.

Well...that sounds like the effects of a nitrous backfire to me. I did the exact same thing when i had a backfire on a 150 shot several years ago. Car spun all they way threw first and second...shifted to 3rd and it hooked...then big time bogged. I lifted just a split second before the backfire. It bent my 65mm tb blade pretty good. I was able to fix it by just bending it back straight.
