My TL may have slung a rod through the side of the block!
I was running a supercharged G35 and the top of 4th pow punnk. Pulled over and car turns off. oil smoke is everywhere. car will crank, but not idle. There is oil all over the firewall. I cannot see a hole but my best guess is i slung a rod.

If you threw a rod, there's a very good change that the engine would not run and in many cases, may not even turn over. If the rod went out the side of the block, you would also loose collant.. check for that, too. If it went through the pan, that would be immediately visible.
Keep us posted and here's hoping it's not too bad in the damage department.

Just thought this might be interesting. Many years ago a fellow in our car club had a 6 cyl Ford that was on it's last leg, so he decided to blow it up. After it blew a hole through the side of the block so big you could see the reciprocating parts turning, the engine still ran and didn't loose any coolant.
Back to the OP. Whatever it is, is not good$$$$$$$$$$$$

Well.... If anything I'd look into an upgrade... May I suggest the TT 3.7 
I don't know if it will fit but damn!

I had to re-read the thread title like 4 times.
Sorry to hear about that man, sounds like a very expensive repair.

Ouch.. that sucks. Sounds like a good idea.. sell s/c and use funds to get a new engine.

maybe it just blew a PS hose~
one can always hope
How is the engine oil level and color?- the coolant and all the other fluids?

i was running regular 4-5psi of boost...it is definatly something mechanical with the engine. flashing CEL and lots of noise. i am going to part out the car and sell it once the new motor is in. i will probably get an 06 evo or something that will hold power

At the same track, I watched a '65 GTO running B/S loose something out of the bottom end of the engine right after he hit second gear. The object went through the pan and left an oil slick about 1000 feet down the track. I've seen all sorts of things at the drags up to and including a man getting killed.

I would just build the rods and pistons and your good to go.... Having a boosted tl is def unique, compared to having an evo like evrybody else does. hate to see you go, but good luck on whatever decision you make.

I agree with you. You need to buy a car made for what you are doing to it. The TL is not made to drag race and it looks like you are doing a fair amount of racing both on track and off. Any car is going to brake if beaten on enough, so I would look at my wallet and see if I can afford to be this hard on my cars. I think Ussi rebuilt a 3.5 stroker with his blower and a HBP, so there are ways of keeping the TL and the blower, you just have to be easier on the car.

It is definatley from the supercharger. More specifically, the lack of engine management that comes with it.
I have no doubt it was detonation, not too much power that killed the engine. Think about it, these cars run on the verge of knocking stock. Then you throw 4-5psi boost on top without pulling the timing back, without more octane, and without monitoring what's going on. The longer you stay in boost and the higher the gear you're in, the more detonation you will encounter.
Again, you have to monitor knock when you have a FI engine. If you don't have a way to monitor it, don't get into boost. No one on here ever listens.
I will guarantee you killed a piston from detonation and it let the rod fly.
I would not think of running a blower without a methanol injection kit. That is the only thing that will make it reliable on a TL.

Wow, that seems like an expensive hobby!
Why not just buy a corvette instead of trying to turn a family sedan into one?
Or is that the fun (but expensive) part?
If I wanted to go fast and burn rubber, something like a used vette sounds like it would be the ticket...

Got it.. makes sense. When you say higher gear, you mean the more time you spend in the vTec engaging range of the RPM band the more boost and hence more wear and tear right? But this I think is the first incident of such a thing happening, others have been fine maybe its daily driving habits, it seems like OP was pushing it to the limits every chance he got. Haha
Some of the old turbo cars like mine ran more boost (15psi) in first and second from the factory and then backed off to 12psi for 3rd and 4th. It also went to a slightly lower timing map in 3rd and 4th. That way you get a little more power down low and protect the engine in the higher gears.

I know this is the last thing you want to do right now, but would it be possible to take pictures of the carnage as you pull the engine out of the car? I would like to see if the rod or piston failed first. This way we can attribute it to either detonation or weak internals.

wow ebay doesnt have em.... u know type......ur not the only one this has happened to......quite a number of times ive seen the TL's in the tech bay getting an engine swapped out because the rods blow through the engine.... Im really surprised as to how thin the walls are. the techs have no idea how theses guys do it.... not even supercharged....just NA and they still blew

It's scary seeing how fragile the stock rods look.

yea u know what i mean lol.
I just dont get it...i know the stealerships gotta make money but y dont they do simple tests on the cars to check pressure inside the motor the compression tests help and let the tech determine whats wrong and lets the customer know...if theres warranty just F**kin swap it out...... whats the big deal. send the motor out as a whole and let the engineers figure out what they screwed up...or it could be bad quality control and the deviation rate climbed....I dunno just my 2 cents on it.

im actually in the process of building custom rods and pistons with the 8lb pulley, should be getting started soon. Like allon said, check with racinghart. Btw are the 5at and 6mt motors the same???

If you're getting custom pistons, now is the time to lower the compression to something like 9.5 and run 10psi boost. At 8:1 on my engine, I can get away with 17psi on 91 octane.
