Anyone blown a stock boosted motor yet?
 

I am debating on supercharging or turboing my car or just leaving it stock for reliability reasons. Just wondering how many people here have blown thier motors with boost so far. I also think this would be an interesting topic for people on this forum to discuss.

Too many variables. But There are a few with 10k+ miles on stock block. Anywhere from 7-16psi.

..... Wow thanks for that link sir.

So I guess I decided to compile the list today:

@Frs300

• Full Blown Turbo Kit
• 93 Octane Full Blown Basemap
• Blew the motor in less than 100 miles, due to the vacuum lines being placed incorrectly on the wastegate and overboosting

@nelsmar

• Vortech Supercharger Kit
• E85 FA20Club Dyno Tune
• Blew the motor after 12,000 miles due to tune running too lean

@alexisfire02

• Larger Sprintex Supercharger
• FA20Club Dyno Tune
• Blew the motor on the drive home from getting it tuned

@Innovate Motorsports

• Innovate Motorsports Supercharger Kit
• 91 Octane Visconti Tune
• Blew a motor while attempting to develop the OTS tune to sell with the kit (kits now ship with Delicious Tuning Tune)

@Jesse@JDLAutodesign

• JDL Turbo Kit
• JDL Tune on AEM EMS only utilizing the port injectors
• Blew the motor up do to melted wastegate line and an overboost

@civicdrivr

• Vortech Supercharger Kit
• 93 Octane Visconti Tune
• Blew up the motor while on the dyno

@shiro

• Greddy Turbo Kit
• Full Blown Tune
• Blew the motor in less than 600 miles believe to be caused by the cam timing and prior damage to motor

@cf6mech

• Accelerated Performance Turbo Kit
• E85 AWDTuning, Texas Tune
• Blew the motor when it crushed a rod bearing most likely due to the tuning

@Unleashed

• Full Blown Turbo Kit
• 93 Octane Full Blown Basemap
• Blew the motor because local mechanic installed a 15 PSI spring and ran a 7 PSI basemap and over boosted spinning a bearing

@Michaeljp92

• P&L Turbo Kit
• E85 JRTuned Tune
• Blew the motor because the car was purposely pushed beyond the limits at the drag strip to find out what the actual limits are, the tune was fantastic, the power was just a bit up there for the factory rods to handle

@Cross

• STS Rear Mount Prototype Turbo Kit with Custom Intercooler Setup
• E85 Moto-East Tune
• Blew the motor running 18 PSI possibly due to cam timing issues and the heads lifted

@C130NAV

• Speed by Design (SBD) Turbo Kit
• 91 Octane SBD OTS Tune
• Blew the motor running between 12-15lbs of boost

@kingkai23

• JDL Turbo Kit
• E85 Prime Motoring/JRTuned Tune
• Blew the motor while on the dyno because the plug on the TiAL wastegate port came out allowing the car to overboost and allowing a rod to exit the motor

@TopSpeed

• Custom Liquid to Air Intercooler Turbo Kit
• E85 Top Speed Tune
• Blew the motor and had a piston fail where the wrist pin attaches. Was making 540whp and being run to 8300 RPM.

@romin

• Jackson Racing Supercharger Kit
• 109 Octane JRTuned Tune
• Blew the motor and a connecting rod let go after 3,000 miles of forced induction and track days

If anyone knows of any others, please post them up.

I know of many. Hardly anyone talks about anything on here. From what I have heard, the autos like to bounce off the rev limiter.

a well tuned FI car is less likely to encounter problems than a badly tuned NA car. it's all about the tune, 100%, nothing else matters.

I 100% agree. The only way to know that your tune is working is to be able to monitor it while driving with the use of a boost gauge and a wideband.

Agree with above - it's all about the tune!

The engines that I have heard of blowing were all related to tuning issues and/or development.

My car is in for a tune right now, so I'd like to not think about this kind of thing right now! lol

Also if you don't get boost greedy you have a better chance of keeping your parts inside the block.
A good tune is esential and monitoring of corse. But if you keep it lowish before you build out the motor you should be okay. I never intended going above 400 at the crank for piece of mind. Once it was built out, crank that puppy up!

Obviously anything is possible at any point. Driver error is a hell of a thing

blew mine...

I forgot about yours. You guys were running only on port injectors with an AEM EMS at the time if memory serves me correctly.

Yes that is correct. I'm finally caught up enough at work that i've started the rebuild lol.

Ah, the tune.:thumbsup:

The tuner :thumbup:

Thanks Bob @DriftOffice!

I added my turbo kit with my car having 1070 miles on it. I have 11705 miles on it now. Still running the same oil from day one the turbo kit was installed. Was suppose to get oil change when when i put 10k on the turbo. I'm 635 miles over. I drive it every day to work and i beat on it everyday. Its hard not to beat on a car pushing 471@wheels@16lbs. But how ever i run e85 and have a great tuner. Also my kit was custom so all the heating issues was taken care of. Like increasing your oil to 9.4 quarts and buying koyo radiator. I would say proper tuning and taking care of the heat these motors produce should be fine. There was alot more stuff that was done but don't feel like going through the list. I'm boost greedy but not going to turn it up any more then it is now lol.
