Well.....you bet I was pissed... I still am. I put a lot of hard work and Money into something and it really was destroyed by ignorance.... I will stick to what I believe in that both situations (both blown Motors) were avoidable. The adaptronic software is so user friendly and simple it's ridiculous. I don't think it's as important to be a pro at the exact ecu/software your tuning on as much as it is important to be a professional when it comes to the chassis being tuned. But truthfully...at this point..it's all in the past. It's not going to magically fix my blown motor/ruined turbo and the best thing I can do is leave it in the past. Move foreward and learn from the experience. One expensive learning experience..and disheartining?..you effin bet. But whatever, can't go back...can only move forward. So forward i'll move.

The first tuner may or may not know what happened..but i havn't talked to or heard from him since.. And I doubt he really cares either way. He didn't say anything at all after the car was hard starting..and he didn't even mention why it was hard starting. I just figured it out on my own. Not to say that he's a bad tuner..but I didn't go back to him because I don't feel like he really cared about my tune. I spent $1200 Dollars at that shop, and switched tuners because of that. The second tuner definitely cared more, but was a bit trigger happy imo and rushed things a bit..which ultimately affected me by blowing the motor. He offered to rebuild it himself and re-tune it. But I just have a bad taste in my mouth from it...nothing against him although Im overly pissed off... but thats not going to change my blown motor. I originally took him up on the offer but after talking to him a couple times afterwards I just realized that I really trust Howard and have an un-questioned good feeling about the guy, whereas whether or not it was his fault.. I just don't have the same feeling about the tuner I was with when my motor blew. Thats a lot of money just to dish out there and rush ya know?



First things first..... I think it's bad luck not to have a name for my car. I'm going to think really hard to come up with a nice name. And the minute It comes to me i'm going to ask an admin to incorporate the new name.

 

Very sorry to hear about your woes mate. I remember when I went through 4 engines in 2 months... That experience was quite bitter and I can fully understand your situation.

However, I am glad you have stucked with it and soon we will see you on the road enjoying your car.

Best of Luck mate

Wow, that sucks 2 engines in 2 months. I would go LS if I was you.

 

THIS. **** that guy.

 

Major Bone-age. This sucks so much. Keep your chin up, and I hope to see you at SS.

 

Porting actually increases potential stress because it allows the combustion chambers to fill sooner. More air needs more fuel which equals larger bang. The end result is higher combustion pressures and temperatures and not the other way around. Anytime you increase the combustion pressures and temps, you increase the stress on the engine. Now in terms of hp, the engine is gonna have to combust a specific amount of fuel/air to make x hp. A turbo is gonna have to move a specific amount of cfm for the engine to make x hp. The only thing porting does is allows these things to happen sooner. Now just because the engine is ported and can make x hp at specific boost, doesn't change the fact that the turbo is still moving x amounts of cfm to make that specific hp #. Sorry about your problems but sometimes keeping things simple can go a long ways.

 

Who recommend running ceramic seals in a track/drift boosted car?

 

^ Good question! I think he wanted something that would take advantage of the balanced engines hi reving abilities? Personally I heard too many horror stories about how ceramics take everything out when they go. Looks like he had a perfect case of that happening here. They have there place! I just don't think a hi boosted application is the right environment for them.

Manny are you going with the Goopy's or ALS next time?

 

That sucks. In for part 3.

 

Correct! I chose the ceramic seals because initially I was planning on revving out further, and taking advantage of the balanced rotating assembly. I was aware of the con's of ceramics but figured if the tune was right.....there'd be no problem.

I'll be using Goopy seals this time around. Only heard good things about Goopy and ALS but chose goopy based off of my gut instinct

Round 3 will be executed based purely off of gut instinct. Any twinge of a "badddddd feeling" and i'll simply say no and move on.



I do think i've found a definite name for my car though. I've been called something for quite a while now and I think it's only natural to give the name to my creation.
My girl officially recieved her christening this afternoon. Her Name is now:

God, you've been through hell and back just trying to tune the car. Thumbs up to you for pushing through and not giving up!

 

Can someone explain for those that are ignorant like myself, how the bad coil killed the apex seal?

 

I just read through the updates and I'm really really sorry to hear about your situation!

At least the Triumph sensor is working well.

I definitely give you MAJOR props for pressing forward and being positive. Having my rear rotor let go on the dyno recently, I know the discouragement. But your situation is exponential compared to mine.

Glad you are sticking with it bro!! You WILL get there.

 

Hmmm now you got me curious. Its kinda hard to run lean when your not properly combusting the fuel. Maybe the spark breakup was causing a resonance in the combustion chamber the ceramics don't like?

 

MANNY, which rotor blew? i'm assuming it was the rear.

to answer the question above: i am assuming manny only has one wideband o2 and it's in the downpipe. if the front rotor wasn't sparking the combustion fully, the two rotors together are creating the AFR that the tuner guy was seeing on the wideband. so basically, the front rotor was super rich and the rear rotor was super lean, so the rear rotor blew from being way lean at 14psi. this is why all tuners are supposed to zero the timing and verify all the plugs are firing before doing any "tuning."

i'm assuming the rear rotor is the one that blew. if it was the front rotor, then i'm clueless and please disregard my explanation above.

 

^ the use of preturbo egt gauges helps to diagnose problems associated with ignition and fuel delivery.

 

Wow, sorry to hear about your recent misfortune...watching that youtube vid was sickening. I literally had that deep down gut wrenching depressed feeling watching it and hearing the exhaust note at the end. I can definitely relate, I went through a series of misfortunes about 5-6 years ago that literally made me store the car and give up the car game and switch to bikes...needless to say I didn't stay away for too long and came back more determined than ever and finally succeeded. I must say the gut feelings work out for the best (I basically built/chose my current setup with my gut feeling). Also good relationship and trust in an experienced tuner is essential, you can have the best motor, but if the tune isn't up to par...a paper weight is inevitable. I'm glad to see you're still sticking to your guns and keeping the dream alive. Good luck in the future.

 

That sucks, but I'm glad are you are not giving up, she'll be back better and stronger!

 

Correct, the rear rotor blew. Except wg spring pressure was @14 lbs...but when I asked him if he wanted me to pull 12V to my MAC valve he said no. Therefore it could've and probably over boosted. Boost cut was set at 17lbs..but that's still a considerable difference. I have 2 wide band ports in my down pipe. One was for my ecu (innovate mtx-l) and the other was the dyno's for the screen readout. I also have dual pre-turbo egt sensors in each runner. But that doesn't even matter because nothing was logged. Bit of a slap in the face huh? Ok..I'm done for the night.let me log off before I start boiling over in anger

 

Was the meth spraying during the dyno pulls?

 

Only water

I am sorry to hear about your misfortune. I say learn how to tune it yourself. I have heard more horror storries about people getting their car tuned then people learning how to tune their car themselves and tuning it.

I tuned mine, as long as you start with a conservative timing map, the air fuel ratio will come, start rich and lean it out.

you will also work at your own pace, which is slow, and you will triple check everything. no one pressuring you to do anything stupid.

 

I look forward to see if you can control boost using the EFR's internal wastegate. A few friends were discussing the benefits of using that setup one night.


What size are you going with?
