I'm Back...

[PRO 5]

Wassup guys! I know that I have not been on the boards in a while and I guess it's time to let the cat out of the bag. My engine went BOOOOOOOOOOOOOOOMMMMMMMMMMMM!!!!!!!!!!!!!!!!!!!! You read that right, I blew my engine. My car has been down about a month now and my new (used) engine came in today. The reason that I did not post this earlier was because for one I felt like s***, and for two I felt like s***, and for three I felt like s***! This is a big set back. The motor costed $1200. That money was supose to go to my clutch/flywheel and fuel managment. But now it went to replace my motor and now I'm set back several months on my build up.

I can't take my car to the 1/4 mile and I have to baby the car because my clutch is about gone. The good news is that my motor came in today and I will start the swap tomorrow. I will post exactly what happened that faithful night with pics of my motor and video (yup I have the whole thing on video). I am licking my wounds and will move on shortly! Just for a heads up, I was running 8 lbs of boost at the time of my little mishap. Later!

OUCH!

 

[APEXistud]

Damn, sad to hear man. Now that's 2 people who opted to go with the T3/T4 and both blew their motor. Hope you're up and running soon......Do you still need those Teins though hehe

 

[bd4awgn]

damn bro that sucks...glad to hear you got a new engine...hope your up and running soon

 

[TECHNICAL 5]

Damn

What happened? Did you overboost,run lean,whats the deal.Sad to hear this man,What popped? The head,a rod,a piston? Give details when you find out.

 

[Tonpow]

You were running w/out fuel managment?

Nothing new is learned unless people try new things and push the envelope...on the other hand I'm sad to hear what happened PRO 5:'(...I was really excited about your t3/t4 setup.

Very interested to see your post on what happened...:'(

I have known about pro5's mishap for a while.
He was running a t3/t4 with an intercooler and a 12:1 FMU
The details are this.
He was running through the gears at WOT
He was in WOT in 5th gear
He had 4 people in the car
It was a chilly night.

Unfortunatley he had a few factors against him. 5th gear runs obviously put more strain on the motor due to it being a taller gear and giving more resistance (kinda like the the highest speed on a 10speed bike is harder to pedal than the lowest)
He had 4 (600-800 lbs) people in the car, this added more resistance to the motor subsequently increasing the fueling demands for the motor, then to top it off it was a chilly night. Obviously the cold air is denser requiring more fuel thus taxing the fuel demands even more and the t3/t4 did not help things out. I seriously doubt that the t3/t4 was the primary cause of the motor going, it just aggravated the situation. Most likley if he was running only 6 psi this would have never happned.

So to sumarize
5th gear @ WOT + heavy pay load @ WOT + Cold weather + T3/T4 is not a good combo on a standard FMU setup.

We have learned from this but unfortunatley at the expense of Daves motor

I hope all goes well Dave.....goodluck

So should one such as myself lay off of 5th gear boost?

 

[Tonpow]

How much boost was he running?

 

[LinuxRacr]

How much boost was he running?

8 PSI. He said it up there.

 

[spoolinmp3]

So should one such as myself lay off of 5th gear boost?

Not saying that but, if it was me and I was doing a lot of 5th gear WOT runs I would atleast get an egt gauge to see what a/f I am running under a high load gear like that. A narrow band 02 sensor will not be adequate for that. I like using a narrow band when driving around ect. It will tell you if you are dangerously lean ect, but is not an accurate tuning tool.

 

[PRO 5]

Thanks for clearing that up for my Terry! I was working on my car today and should have my motor out tomorrow. I will turn down my boost to 6lbs and I should be fine for now until I build up my bottom end and go with a good piggy back or just put up the cash and get a stand alone. I am keeping my spirits up and will continue being the guinie pig for you folks and keep you updated with my T3/T4 endeavors!!! Damn I need a clutch!

Man that sucks Dave, my turbo is about to kick the bucket, I am probably going with a T3\T4 with a stand alone. But I feel your pain, the first turbo that I put on didn't work, I payed 620.00 for a refabed T-28 then I paid 480.00 for the rebuild. So thats 1100.00 for a turbo that is going out again. So people learn from my mistake also, BUY A NEW TURBO. Mine smokes like you wouldn't believe, due to oil leaking through the seals. The guy that I bought the turbo from is saying that I am running to much oil PSI. But is impossible if I am running the same size oil lines that everyone else is using.

 

[big_ben]

The oil pressure could be a problem. My brand new turbo that I got from Terry started to smoke as soon as I put it on. So there could be too much pressure with a few cars. Maybe it's just a defect in a few cars. Who knows.

Ok the question of the day is how bad was your car smoking Ben. My car would probably cover a building with the smoke it puts out:wtf: I am wondering if that is the case then how could you lower the pressure of the oil so it wouldn't leak through the seals of the turbo?

 

[big_ben]

Mine was smoking pretty bad. It was at it's worst when the A/C was on and when I hit the throttle. There are ways to lower the oil pressure, but you should see what pressure it's running at before you do that. Someone else with a turbo also needs to check their oil pressure to see what the norm is.

 

[1sty]

So much for the Protege Knock sensor.
Are you guys positive oil pressure is the issue. Non of the BEGI/FM turbo setups have reported this issue and I believe its up to 13 cars now.

 

[big_ben]

I'm not sure, but you never know, and we wont ever know until someone with a turbo checks the oil pressure in the supply line, and then we will have a standard oil pressure. Until then, who knows?

 

[1sty]

Well it woun't be me. Its just too damn cold out now to screw with anything. I'll have to wait til April.
Damn I need to move!
