Problems with Turbocharging on gas? - Ford Forums

Anyone else had problems with blowing head gaskets on there turbocharge gas vehicle, i don't seem to get anymore than about 10-20 thousand km's out of one before having to replace it. The car has been recently dyno tuned and according to the car its running spot on, but its full throttle mixtures are at 12 to 1, and in my book on gas thats a bit rich and would be making cylinder temperatures rather high.

I seem to get different information on gas from anyone i speak to, some say that it doesn't hurt an engine to run lean on gas, it apparent decreases cylinder temperature, some say you will destroy a motor if its to lean on gas, but the one thing they all say is if its too rich it will burn a piston out. But how rich is to rich? stoch is 15.5 to 1

Too lean will cause your engine to explode (so i've heard)...not the best thing.

Try a copper head gasket if you're not already using one. they're reusable and a hell of a lot stronger than the standard ones. They just cost more thats all.

Good idea, but i would rather get rid of the reason it is blowing the head gasket, than mask up the problem by using a better head gasket.

With a normal head gasket it will break normally before a piston will, last time i put a better gasket on it didn't break and all six pistons did.

run a acl race series one, they have thicker firing rings on them and are made out of a good graphite material.

is ur motor o-ringed?

if not ur best off getting it done to the block, as the falcon heads are a bit soft and suffer resession when o-ringed and fully torqued down

so have the block o-ringed and install a race series gasket.

gasket will still break but will take a bit more to blow it out.

as for the gas fueling... i'd say drop gas reserach astralia a e-mail or call them and discuss some options.

cheers.joe.

How much boost are you running?

How does the car actually run?

I'm only running small boost and haven't done the kms you have, but have drove the piss out of it, alloy head, ohc, and it loves it!

The only thing is that we had our mixture a lot leaner under power.

10PSI at the moment, and the engine runs great, nice smooth, plenty of power. The head is already O'ringed.

Try ringing this guy:

Dave Elliott of Gas Tune in Canberra (02) 6293 9033.

He might/should be able to help with the answers to your questions - just don't tie him up for hours at a time when there's no way he can bill you for the time spent on the phone.

Fix the problem as inlower compression,more retard timing or richer/ correct mixture.Otherwise it WILL keep blowing gasgets!!! Thicker gasget may solve the compression but keep in mind you are loosing your quench area and will loose power..If it's blowing gasgets something is out of tune and the rest of the engine will follow..It's obvously detonating at some point...?? If std eec[tune] there maybe too much advance in mid range where boost is realy working for you...

look for uni chip, or even resort to mech advanced dizzy that can be set easly.
