^ I hadn't seen a TL with traction control installed either. SpeedFactory hadn't seen a TL installation. I was also hesitant since there's already traction control I didn't want to have two competing systems if I forgot disable the Acura TC. At this point I'll probably be offloading the hondata TC.

I would be all over that if I wasn't running my gsr in the SCCA STX class this year.

Picked up my TL tonight. Man I missed the turbo goodness! with the built bottom end they were able to advance the timing and up the boost a little so my current numbers are 406 whp and ~380 torque. I'll post up the dyno a little later.

They did notice that the car was pulling a lot harder on the street compared to the dyno though. The TL would hit 13psi of boost on the dyno, but on the street it would go up over 15psi so they had to back the boost controller down so I'm at 13psi. I think some street tuning is probably in order to make sure it's tuned properly.

In the mean time, here are pics of the pistons and rods installed.

I wantz so bad

Videosssssss. Pretty pwease?

I'll see about shooting some videos this weekend or early next week.

And this is on a 5AT no less... jesus. Looks like there is hope for us 5AT folks yet. How is it in fourth? No issues with it dropping out of VTEC?

UTAH TSX

Great numbers, my son is going crazy waiting to get his going again, DEFINITELY have Vit Viper Tunning do a street tune the only way to ensure a long lasting motor IMO, have fun driving that 400 WHP beast

Congrats on getting it back! I bet that thing is fun to drive. Is the 400 whp with meth?

maddogtheta

It's a blast to drive. I am running the water/meth kit at this point, but it's mainly a safety measure.

maddogtheta

I haven't been anywhere that it's safe to push the TL in fourth so I can't speak to whether it drops out of VTEC or not. It's ridiculously fast in first through third, I imagine the speed continues with 13-14psi of boost even with the taller gearing in fourth or fifth.

UTAH TSX

How's everything going ?

FamilyGuy

Awesome must've a blast to drive.


Hey are any of you guys replacing any OEM sensors to make sure you're getting decent accuracy when tuning?

O2 sensors can drift over time, and I think the air intake temp sensor can go way off as well. What about knock sensors? Are these known to drift? Seems risky to invest thousands in goodies without a few hundred in new sensors.

maddogtheta

It's going great, Vit's been helping me with a more refined tune which is very close to being done. I'm just enjoying driving around in my turbo'd TL

UTAH TSX

How about some video and sound clips ? really interested in how the turbo sounds out back

We the people of Acurazine, humbly request some sexy video footage of said mythical beast, the working turbo TL

Bonus points for making an auto kick ass. I'm striving to do the same in a year or so and you've given me hope

maddogtheta

I'll see about getting some video this weekend, it's been rainy up here in Washington so I may only be able to get interior video. I'll do my best.

I vote to weld the wastegate(s) closed and see what it can REALLY do!!!!


Lol.

Two weeks ago my CEL came on for misfires in cylinder 2. A compression check showed that it was at 120psi, the other cylinders were all at ~200psi. The engine is currently being removed to see what is going on now.

I'm pretty upset and frustrated at this point. I'm having SpeedFactory put in a stock engine and exhaust while I take a break from this project to recoup my sanity and save up if I decide to try again. Depending on what the cause of the misfires in cylinder 2 were I may be giving up on a rear mount turbo or turbo'ing all together.

I'll get post some more info on the damage when I get an update from the shop.

Sorry to hear this, The joy of boosting you just never know some last forever some just break way to fast

Very sorry to hear this.

How much boost were you running?

I'm very interested to see where your failure is. This was the same thing I had on the stock pistons when I broke the ring lands. Any idea what they setup for the end gap on the rings?

screaminz28

iTrader: (1)

Sorry to hear this. I know the last post you had was 406 whp and 380 tq. Was it still at that point with 13 psi or had you turned it up? Was that tuned with meth at all or just 93? I thought you had been running meth but it's been a while.

In either case, other than catastrophic random piston failure or as KN mentioned possibly excessively tight ring end gap, what else could be the possible cause than detonation?

I'm starting to lean towards a J&R ecu now just to take the oem crap out of the mix.

Gerzand got his ride back on the road and is pushing mid 500hp and I am pretty sure using the hondata firmware.

Hopefully we'll get some answers for where his motor gave up.

my money is on the sleeves. They probably got jacked up from 13psi. but that just my guess

UTAH Type-S

This is horrible news. Im sorry to hear this. It sucks being without your car. I know this all too well

screaminz28

iTrader: (1)

I dunno. Wasn't libert pushing 18psi before without issue? He had a JnR though. I think right now, Gerzand is the only FI Hondata running right now in the 450+ range.

FamilyGuy

What was that guy in Canada using? The one that hit 700hp. IIRC his name was Tony the Tiger.

Taken from Videos & Updates

They completely deleted the factory ECU I believe, deleted VSA, deleted DBW and converted to cable throttle.

doesn't he have LA sleeves

My utmost respect for the work done on that car, but man do you love the 3G TL when you put that sort of money into it. Like putting the value of the car on mods for it...

N1h1l1ty

He did it in stages - He had a stock bottom end J32A3 first that was running a smaller turbo and only tuned on AEM FIC making "only" 400 - 450 wheel. After they cranked up the boost and blew a rod he went full built.

Its pretty nuts that he's got the A3 revving to 8k +

Luckily the shop that built that engine is local to me

I'm aware and it just proves my point.

Im on 9psi currently at 502/440. At 11psi i was 555/495 and couldnt try any other boost levels (up to an estimated 18 at max blower output unrestricted) because I need an even larger fuel system which I am now beginning to build (twin 450lph e85 walbros and 10an supply)

maddogtheta

I was right around 12-13 psi. I'm not sure what the setup was on the end gap of the rings.

I hadn't turned up the boost, and I was running 50/50 water meth. After a tune-up from Vit I wasn't having any knock during WOT. Once the engine gets taken apart I'll update with what SpeedFactory finds is the cause.

6spd-GERCO

This sucks

screaminz28

iTrader: (1)

Damn, built bottom end, water/meth, and tuned by Vit. I'm REALLY hoping (for everyone's sake) that it is something other than a broken ring land or popped piston. Maybe a burnt valve or blown headgasket. Did they do a wet compression test in the cylinder that read low?

I started thinking about this blown motor, as well as Uath's over the weekend. I am curious, in both of your cases, did VSA engage a lot, or perhaps shortly before the engines went?

I have been searching for a root cause on these failures, and while some may be content to just say "the motors are weak" I disagree, especially with the popularity of the J's in sandrails, and Honda swaps. It appears that ONLY TL's with stock ECUs are cracking ringlands and blowing up motors.

I can't find any whitepapers or technical info on the VSA system other than it is Honda's TCS combined with a slide control system with a yaw rate sensor. If it retards timing a lot, then adds it back very fast, even if not excessive, could this be contributing to the issue? I know big timing jumps between cells is not good, even if they are technically 'safe' timing values, just the big jump can be dangerous. Something to think about anyways...

Any word from the shop on what all was damaged maddog?
