Blown Motor survey

[dragonballspeed]

For those of you out there that have blown your motor, I post these few questions?
How much boost where you running on a daily basis?
What type of boost controller did you use, a MBC or EBC?
Also include any other mods other than an exhaust or CAI to make more power.

For the other MPS owners out there that have lowered you car, do any of you run 18 x 7.5 with 45 mm offset on 215/40/18 or tires close to that size: if so what is the lowest you have been able to get your car without constantly rubbing the front of rear fenders?

Last anyone know of a good bodyshop in the Dallas, TX area that can roll the fenders? Thanks for all of your input reguarding any of the questions.

Funny, I was just gonna ask the same question to those who've blown their motors

[Micah]

8 psi, sometimes spiked to 10.

everything is in there

Again, you guys need to realize more factors come in to play here than just the amount of boost. Temperatures, general climate, elevation, stored heat, gear the car was pulling in, weight in the car, etc.

You have to figure out ALL of those conditions before trying to assume what's "safe" for you and whats not. You can't just say "Well, I'm in Seattle so I'll raise my boost up to 14psi like those crazy Texans are doing."

This isn't a N/A car where a bolt on adds near constant power in whatever conditions you're in. Well, then again, even in that case, all of those variables will have an affect on power output.

Also realize that we're in a winter season. That means dense air. Simply put, dense air equals more power. So just because you were running 10psi a few weeks ago does not mean it's safe to do so right now. Just throwing out numbers here but 10psi those few weeks ago may have given you a total of 200hp but now that it's a bit colder, 10psi may give you 230. That's just an example but you get my point... Hopefully.

have It may not be as fun but be responsible and turn the boost down when it gets cold.

Cliff notes: Don't assume that just because one person blew their engine

This question does not answer anything that you *NEED* to know about the real issues.

I dont have a msp, i blew my engine @ 15psi, couple of 20psi jumps, of course...no fuel to compesate.

I think our pistons do not hold well more than 15psi

You didn't have a T25, did you?

You're not going to get the info you want unless you specify exactly what you want... like MSPs with T25 turbos, or something a little more specific. What boost people are running with T3s and fuel management or something won't gove you any clue what is safe for a T25 boosted MSP...

[dragonballspeed]

for those of you trying to anal and tell me you need to be more specific about atmospheric conditions or MSP's with any other turbo than a T25, just read the question its simple. I'm just trying to get a compile an average for those with MSP's with stock turbo and stock internals. Just trying to figure out the breaking point for these motors so that we can provide a general idea of what people can expect from generic conditions. Yes, I know that ever condition is different but there is no need to be that specific.

[Newf]

yeah, i think his question was clear.

this is a post in the msp section. I was pretty sure he meant MSP turbo's, not every other protege.

[BrianV]

I'd like to know if most people blowing their engines are blowing them closer to redline or closer to max boost (4000-4500 RPM).

I have yet to take my car to redline so I'm curious.

I'm trying to tell you that 9psi on my car in Texas will be WAY different than 9psi on a car in Seattle. If you don't believe me, research the way your car works before calling people "anal" about trying to clarify your generalistic question.

Christ man.. Do I need to come drive your car for you?

[BrianV]

No, I've seen how you drive.

I did get mine up to 12 once and it felt AWESOME (about 65F out).

Other then that trip (which only hit boost twice), I leave it at 9 which doesn't feel that remarkable over stock.

I still am curious if the engine blowing is happening closer to redline at lower boosts or closer to the max boost point.

I don't race my car or drive my car ridiculously fast, but I love quick surges of accelleration which is best felt from 3000-5500 RPM.

Let me know next time you meet up, I'm totally down. I gotta get out and do something social with my ride.

I'll try and come out on Sat night. Usually that's g/f night, plus I used to meet at Chili's at 183/I-35 on Sat nights and it got really riced over. 1.5 years ago the crowd was a lot better, but the recent car meets seem kinda whack. I'll check one out since it's been about a year now.

Any day meets, there are a lot of Austin MSP owners, do they ever get together?

[t3ase]

The crowd up at Vans was abnormally large last time I went.. Like overflowing into the Petsmart parking lot. It may be catching on.

As far as the austin MSP owners go, I'm the only one that seems to be on the forums now and I just can't get anyone else to care enough to meet.. I dunno.

I thought that as well, but the first two posts about blown engines were from non-MSP drivers. Could be useful information, but then we'd need to know how much CFM their particular turbo was pushing at what boost level, then try to get the same figures for our T25s, and guesstimate from there.

Just trying to clarify, I'm sure most of you are well aware that 8 psi on your average T3 is a lot more air than 8 psi on your average T25, but someone here MIGHT not be clear on it. Trying to keep things straight for any lurking noobs or whatever.

i'd drive up to austin for a meet. i'm usually up to no good down in san marcos anyway. i wonder how many msp's we could get together for a meet anyway? *pondering thought*

my car was stock cept for the K+N cone filter when the engine blew

Finally, I know who the other member is that hit Lime Creek Road with me and T3ase.

[BrianV]

So can anyone with a blown motor answer my question about RPMs at blow point?

Closer to redline, or closer to max boost.

My bet is going with max boost, but still am curious.

[twiztedjeckel]

i know i wasn't romping on mine nor was i boosting alot. i just heard things making noise and then the engine started acting real unhealthy like

[KYMP5]

i was close to redline. around 6500rpm, and 0 boost. i dont have an msp but a blown motor

[Turbo Matty P]

my motor popped due to a faulty ignition module. The boost crept from about 5psi to 14psi before popping. Daily driving I estimate the boost was between 10-11psi. It pulled very hard and would often put down so much power it would glaze my clutch.

Ultimatly boost did kill my motor, but only because of the headgasket that was blown by the ignition system. On a non-boosted motor a blown headgasket causing running problems. On a FI motor it'll destroyeverything that moves. (my case).

[Turbo Matty P]

p.s. my rpm's were held at 3500 under a full load (chasis dyno)
