No intercooler

Parse` our STI's lost boost. IE: No top mount or one of our FMIC pipes fly off.

Do you think a mile or 2 of driving is kosher?

When I had the Evo I blew off an IC hose and the car crapped out. But it seems that when my STI's IC couplings fly off I seem to be able to drive it still. Though I know this drinks down gas.


So other than running pig rich what else could happen?

*Not really worried, I think the ALS and Launch control on my hydra will kill the engine first than this. Just a thought.**

I am going to try and go out on a limb to help you out but I can't say I really understand the question your asking...

your thinking of driving around w/o your intake pipes hooked up? Ummm... I wouldn't. If your MAF is still operating and your turbo is still compressing but your not boosting into your intake manifold - your going to run terrible and may cause damage into your engine.

If I had to drive somewhere, i would disconnect the intake pipe from the turbo and fit some sort of cheep "hardware store" dryer flexible ducting between the intake pipe (which has your MAF sensor) and the intake manifold (removing the TMIC or FMIC pipe). At liest this way, your car is injesting the same amount of air as its senseing and you can get where you need to go... don't drive it far though.

well your engine will run like crap unless somehow
1. MAF was still able to detect air going in the the engine
2. force WG open all the way to prevent turbo to spin.

should be fine as long as you coover the hole with soemthign so debries can't go in
