I recommend you just weld your wastegate shut, that way you won't pussy out.

hello guys, i changed al metals in my block, polished the head and changed all the seals also the valves, so the engine is completely rebuilt. How many Psi do you think it may hold??

what if he reinforces the welds though? I'm guessing 24.69psi is ENTIRELY possible, though it hasn't been tested by Paul Walker

Dual NOS bottles should only be used when compound charging, one before each compressor wheel. Bonus - when you're compound charging, you get four times the boost instead of twice the boost!

most def
and make sure to scream MONIKAAAAAA |
30psi on a GT1241...
Or 4psi on a gt4708. |

"How much boost can it handle" without further details is one of the dumbest questions ever. In order to be able to make any sort of estimation we would need to know all the details. You changed all the metals? What kind of rods? What sort of turbo/manifold/exhaust/etc? Engine management? Who is tuning it?
It is known that, on average, stock rods tend to fail somewhere around 250 wtq assuming good tune and such. if the boost comes on hard and soon it is more likely to break than boost onset softer and later. |
You put new bearings in but kept the stock rods?
Banned for trolling. |
i didnt replaced rods because my main point wasnt based on Turbo. My engine was suffering of low compression in 3 and 4, so i replaced piston rings and bearings (I have pictures of the complete work).
|
That sucks for you. Now start reading and let this 7-year old cancer-infested thread die already.
|
I just threw in some h-beam rods, im sure it will be good for 350hp, which is my final goal.
|
Should be fine for a street car. For track use you'll need stronger oil pump and other stuff.
|
isnt the stock 1.6 can handle around 250hp with stock internals??
It not right to ask how many PSi a engine can handle but how much stress it can handle |

torque [and clyinder pressure] bends rods.

If it can how well can it handle it. If you run 8 or 12 psi usually then boost up to 15 sometimes would it hurt?
what about no tune. what boost pressure can i run with no tune till i get ecu ? |
First post. In a thread that was bumped in 2012 from 2006. 4 years later in 2016.
Must be a helluva hibernation chamber. |
