Ok this question has probally been asked a million times, with the setup listed below.

im not after boosting the engine to hell and back just say 5 psi driving around

1. could there be engine damage with running a turbo at around 14psi?
2. is it a case of the engine just wont be around for so long?
3. Is there anybody who has run a turbo setup on a stock falcon around 14psi for a while with no problems???



Engine setup:

Ef block ed head
Highvolume oil pump
balanced crank assembally
ACL comp tri metal bearings, 1" extra oil clearance
duralight 20"oversize pistons, standard ef rods
Acl Moly rings
Genuine ford MLS headgasket, Coated with hylomar
head shaved to unknown
Crow cam- xr6 eqiv springs
ed xr6 cam
Slight porting


Thanks a heap

It depends on how well its tuned, and how well you screwed it together, and how you drive it

Mine stays at 15psi now.

It will be fine if the motor is tuned well and in good condition.

the week points in his engine would be the std rods.. otherwise if he had better rods and head studs even 28 psi would be ok :twisted: ..

You'd get a million kms out of the motor on 15psi if you always drive under boost :lol:

It all comes down to driving habits at the end of the day. Rest a brick on the accellerator and of course it will fail in due time. Take it easy with the odd thrash here and there and there's no reason why the car won't outlast you.

light throttle, low load = off or under turbo spool...

my engine has been on the receiving end of 12psi for close to 2 years now and its still as healthy as the day it was fitted...

With a stock falcon I have have found the ring lands collapsing around 15psi+ and the head gasket is an issue.

You have a MLS head gasket which has sorted that problem and stock ACL aftermarket pistons. At a stab the ACLs cast may be a bit stronger than the stock Ford piston (which I think are made by ACL anyway) but I would think the aftermarket piston is probably made a bit better.

So you might be fine. The rods are definately OK.

Power: 482 rwkw

Location: Penrith
NSW, Australia

I know a guy who races at 360 rwkw [E85 / 385rwkw C16] with std assembly..
He changes at 5500 rpm...18 to 22 Lb boost..
If you keep rpm down with good tune it will last as long as std engine
with frequent oil changes etc..

BUT keep rpm down, use the extra torque !!!
300 rwkw seems the durable level for BTR trans with cooler also...
