My TL may have slung a rod through the side of the block!

are you going to rebuild and sell or part it out?.. too bad.. good luck on your next domestic rocket.

SC TL to RS4 to 911
David, man Ty told me about this and I had to read sorry to hear! Funny thing is I'm putting my TL up for sale and I was going to part it out but I think if I get a offer of more than 20k I'm just going to sell it as is...

Probably not.... You would need a slight upgrade. What kind of blower did the factory supercharged T-birds use or the supercharged Buick 3800s? I know both cars used a larger blower.

The higher the gear, the higher the load on the engine and the more likely to encounter detonation.
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.

Would a water methanol kit (snow performance) have helped with this problem. I'm just learning more about them but they increase octane and will prevent detonation.

Can you even bore out a 3.2 to 3.7.. or do you mean 3.5 to 3.7? A solid 3.7 would be nucking futs.

More octane, charge cooling, and more fuel, all of which will make the TL reliable under boost.
I run up to 28psi reliably with meth injection on my turbo car but run into detonation over 17psi on straight 91.

awesome to hear....since I just bought a snow performance methanol kit from excelerate for my soon to be blown tl.
Most definately. I believe that the supercharger should only be sold with a methanol kit included. Meth injection is the absolute best thing you could do to a blown TL.

Dude, sorry about your engine. I feel ya, I blew my engine in my VW with too much boost. sucks when it happens, although I laughed when I realized the damage.
The super coupes came with an Eaton M-90 and ran around 8.5:1 compression. I think the grand prix gtp's ran the same charger with different rotors.

sorry to hear about this.... how long was the SC on the car and how many miles on the motor?
maybe you should just keep it all N/A with a tune that would be nice
hope everything works out from one ssm to another ssm

just ran into this thread, sorry to hear david 
im 100% sure detonation was the culprit. did you at any time before this incident hear any kind of pinging? did you keep a close eye on your wideband and monitor your a/f at all times?
i always emphasized to all you boosted peeps, to trash the ACM and go with something that you can adjust the a/f and most importantly retard timing. either it be from dual emanages or AEM fi/c, -1 degree for every pound of boost is the usual and a must especially for an engine not intended for boost with 11:1 compression.
about the methanol injection it wont hurt IMO, BUT i really dont think its neccessary for only 4 psi of boost and your not going to receive the full benefits from it anyways, without proper engine management. a proper tune IS KEY and will keep your engine happy and running safetly.
GL with whatever you choose david, but i agree with ssmtlmv. if you buy an evo, you'll just be another evo and a downgrade IMO. TL with SC is priceless!
EDIT: WOW, i just saw your thread about blowing your transmission. damn, when it rains it pours doesnt it. dont really blame you for wanting to sell now

Did you ever find out why the engine was detonating? I think I saw an old post on here with pics of the tops of pistons that looked pinged to death. Not sure if it was yours. Have you opened the motor up yet to see what the tops of your pistons look like?

This is why I think methanol is a must. We know the TL runs a little lean under boost and most people don't have a way to retard timing. Two problems and methanol solves both of them with fuel and octane.

I think it's safe to say every blown TL pings. Even 4-5psi on an 11:1 motor is going to ping without retarding the timing or adding octane.

Yeah I remember the whole pinging discussion lol. My question is was the detonation the cause of the rod failing or was it just the rod failing due to the higher than designed cylinder pressure from the blower. I am curious because I want to up the jetting a little. Knock I can check and compensate a little for but if the rods are just gonna puke then maybe I should just leave it where it is.
But it's easier to sit here and say that it's ok when it's not my $39,000 car lol.

This is unfortunate my friend.
My word of advice, just try not to open the throttle wide open everytime you get next to a vehicle that might want some.
For instance. The other week at the light, me in the TL. Dude in his red v8 m3 beside me. What did i do? Nothing. What did he do? Nothing.

The last poster that had tossed some parts definitely had some SERIOUS detonation issues. Thing that puzzles me is why is the ECU not pulling MORE timing if its picking up knock. This guys piston tops looked like a bowl of silver colored oatmeal. This is really annoying me. If we could figure out a way to eliminate the knock then I agree we can make more power. (I have a spare motor to play with JIC) so maybe Ill take a look at the knock retard with the current jetting and then up it a little and see what I got. I am gonna also take a look at a few of my piston tops with a boroscope. I have run a least a dozen bottles thru the motor so I have given it plenty of time to see if there is any noticeable markings to the tops of the pistons.

i just picked one up a clean used one a few weeks ago.. my thread is in car talk...
the V8 gives you a good base to start with and the engine can handle boost... but be prepared to shell out 30k for FI... it isn't cheap... come to think about it, nothing is cheap on Acuras or Lexus...

If you haven't priced out a NEW block from Acura.... just to let ya know, complete bottom end is under 1K dollars for a 04+ TL.
You can probably get a J37 for bout the same price out of a 09TL SH. The heads would need some work done in order for the combustion chambers to match with the bigger bore.
J32s detonate, J&S Knockguard works wonders. I was able to hold a VQ30 together in a Maxima with stock ECU, Emanage Ultimate with J&S for knock guard to 450WHP daily. Its all about tuning.
