I think my engine poped!
so check this out... I have wanted to race my car at the strip for about 3 years, i finally get a car and on Firday night i am driving to opening night of the drags to race my car, and about 5 mins away I give my car some gas to get in front of a truck and next thing i know my car just stops moving! so i pull over and pop the hood, and the engine is shaking like crazy, i checked for vacuum lines and they where all on. but if i gave the car any gas it like bogged it down and would stall sometimes. I have no i dea what it is.(detination ect.) also i have a warrenty on my reman, but i dont know if i have voided it by doing some of my mods. anyone know what could be up with the engine or if i can still use my warrenty? thanks a ton guys!!!

You don't have any engine management listed in your signature, please tell me you have EMS running all those mods. It sounds like your motor is dead to me. Both rotors must have lost compression.

a boost controller wont be able to control your boost with that many mods. since you have a mp, you have no back pressure, so your boost probablly spiked through the roof. get a compression test done. and double check all your vacum lines before you rebuild the engine.

Depending on your car, (since every car is different) It is possible to keep your car in a safe boost level. However the safe boost level for the stock ECU, is 10 psi or below, and keeping the boost below that with a midpipe is very difficult. I see that you have non-seq turbos though. Its usually alot easier to control boost spikes with non-seq so,
Even with a Power FC, most people suggest you get the car tuned because it could lean out a bit with the midpipe. The stock ECU has some leeway on the boost level, so you might get some lucky breaks, but with the power FC you dont have nearly as much room for error.
regardless, Everyone is jumping to the conclusion that your motor blew. And another thing, you said you were passing a truck... well were you flooring it to pass the truck and went through the revband? Because if you were not, I highly doubt you boosted to high.
First if you have a compression tester, test the compression. If you dont, do the poor mans way of testing by taking out a sparkplug and turning the motor over. if you feel three solid pulsations of air from the spark plug hole, then you could be ok. However if you hear one, then a period of nothing your probably in trouble.
How many miles are on your motor? It might have just given out.
Sad to say, did you check your map sensor hose?
Have you checked to see if your boost ever goes past 10psi with the midpipe?

FD3RotorTurbo, dont jump to your motor being blow untill after utest the compression. But everyone right in saying that its stupid that you are running those mods without an aftermarket ecu

I have only blown one motor so I don't have a lot of experience but I just blew seals on just one rotor and could still drive the car up to 60 MPH the engine also shaked like crazy at lower RPMs, and bogged down easily. If he had something like a boost leak etc. the car should still be able to drive ok. There is a small chance that his motor isn't blown but all the symptoms he listed sure point to that.

The symptoms could lead to it, but the way everyone came off, was like oh it has to be this, and there isnt even enough info to even say that.
If he was passing a truck, he could of floored it, or just gave it some gas. Giving it some gas isnt gonna put his boost over 10psi. Most of the time creep doesnt even come into play before the secondary comes online, which doesnt even happen since hes NS.
His motor could have gone from alot of miles, anything really. There just isnt enough info to tell.
oh, and the map sensor hose being off gives the exact same symptoms as a blown motor.

Do a compression check. I've thought I've blown my motor a number of times, and every time it was something minor.
Look at my mods. And I'm running the stock ECU with boost at roughly 8psi.

Car made 295 rwhp and ran pig rich after the primary to secondary transition. Not trying to hi-jack the thread. Hopefully it didnt blow and you can continue to enjoy your car.
