I would have tried to hit them for towing as well, because that is bullox. Ol well. Thats what we get for performance pieces.

I think Boomba did as much as can be expected. A bent plate wouldn't be any more repairable than a snapped aluminum one. It could never be sufficiently straightened out to seal properly, and bending it puts it through a signficant fatigue cycle which also makes it less desirable to try to reuse.

I can't expect them to cover the towing.

I wasn't expecting the parts would cost that much.

Agreed, Boomba did a good job fixing it quickly. With a bent plate, I could of limped the car home and not called a tow truck. If I could of bent the plate back would it would of been even better and give me close to a stock idle. this would have been only been temp situation just to make it home. I would have repaired the TB correctly after that. Also, there would have been no debris in the intake manifold with a bent throttle blade.

So let me understand this, you did NOT use nitrous, correct? That is just from _normal_ back fire?

best bet is to remove the throttle plate and have a replacement made out of stainless.

This is a very rare occurrence. Could it possibly be the TB's fault, not the cars fault? Who snaps a TB?

I have been running a boomba tb on my car at horsepower levels from 470 to 650+ with backfiring/meth/e-85 all backfiring at times and have never seen this so it had to be one serious backfire to hit the plate like that. I've had 0 issues with mine and as you'll find by reading around the forums I don't recall a single other case that I've read about but plenty of positive. The throttle body is awesome, I've had nothing but a great experience with mine.

Surely you all have read about the Evo's with bad transfer cases, bad motors, etc from the factory and you all still bought one right? Are you saying if you had known about the Evo "issues" you wouldn't be driving one? Of course not, that's just silly.

Well I haven't snapped a plate off, but I had a Magnus 75mm that the shaft broke where the screws go through to hold the plate in place and sent the bolt down a cylinder and ruined my 1st motor.
Then I bought a Wilson Manifolds 75mm to replace it because they are about the best name in TB's, same **** happened that time about a month into driving the car, luckily it didn't ruin anything this time. So I sent it back to them to be fixed, when I got it back it made it to the end of my driveway and the plate stuck wide open because they had forgotten to loctite and stake the bolts when they put them in (luckily again the bolt stuck in my manifold). So I called them to let 'em know what happened and that I was just going to get my friend to put new ones in and then weld them to the shaft so they couldn't go bouncing down the cylinders again.
A week later the shaft broke from the heat caused by the welds.
So unless you stick with a stock or stock ported TB, I don't believe there is a really good/safe option out there.

No way should a throttle plate break off, that's a huge liability and safety issue. I believe Toyota had to do a recall that cost them billions for cars that went to WOT.

I'd recommend putting your stock one back on the car....

how long was it on the car before it broke?, I have the same TB on my evo havent had any issues with it.

Dang that blade snapped off clean!! At least it didnt happen on the freeway and everyone is safe..

Nope. No Nitrous used.

You should be fine. I think this is rare case.

I thought about that.

Well, it did bend the other blade still intact so something caused it to happen.

I didn't notice anything until my RPM jumped up to redline!

Agreed. I've had good luck with the Boomba till now.

Wow, yeah you've had worse luck than me!

Thanks David. I'll think about it.

Damn straight!

Yeah, I was glad I was able to cut ignition and pull over safely in a parking lot quickly.

Thanks for all comments. My main point was to warn others that this could happen with some throttle bodies if their blades can't take the abuse.
