I heard they can only take up to 10 psi. can they have more compression?

 

Depends on the turbo. A little T25 might be able to pump out 15 psi just fine, and on a bigger turbo, say a GT35, you would only be able to handle 5-7 psi before power becomes too much for the internals.

It's all about CFM not PSI, unless you're talking about the actual intake or manifold.

 

they would break at a certain HP level, not a psi level. i would say it can probably take 320-330bhp, so maybe 275whp, however no one has really ventured up there on a stock bottom end, nor could i say how long they would last at those power levels. the actual psi level will be dependent upon the compressor. I have no idea how much power 10psi would be from your turbo, so i cant really answer the question in terms of psi. I will say this though: your ghost icon is awesome. I need a hunterKiller hydralisk icon

 

^^Ya I forgot to add that in there about the compression in the question, i was at work and so tired cause I worked 16 hours last night. Also I just purchased my new rods and pistons with an 891 ratio so I can push more.

Hell Ya! Ghost is the most bad ass unit there is! lol NUKES man

I know Im jacking my own thread but hows the car situation?

now back to our featured present question...........

 

i'd worry about your intake mani

 

they say its good up to like 350 hp i think, but I have to look in the book again, I could be wrong, it probibly can take more than that

 

yeah, what kind of intake mani do you have? i'm hoping 2.4 cause the stock 2.2 ones like to go boom with higher pressure.

 

i know you are asking a turbo question, but 07cobaltguy is running the S/C setup on his 2.2 and has stage 2 pulley on it, has to be running at or close to 15psi

 

i ran 12 pounds on my GT28

and i ran 16 PSI on the supercharger

 

I'm going to run 15psi on my m62, as far as how much psi ur engine can take no one knows, yes to much pressure is a problem, air enters the engine already compressed, than it's compressed more, to much initial compression could **** the pistons up

 

guys, psi from a M62 and PSI from a turbo are NOT comparable.
Its all about the hydralisks tho dude.. ghosts are badass, but mass hydras own all.
as fr the car...the car is fine, the ticket situation is looking ok, but very expensive (im almost $3k in the hole for attorney expenses), but it wasnt impounded or anything so i can still drive around.
I would upgrade to the 2.4 manifold tho. flows better and is stronger, and its only like a hundred bucks? maybe two hundred

 

I hate when zerg masses up lol im a terran guy, thats why you use science vessels and bug spray them lol works very well.....oh man now i need to play starcraft again lol

Thats good, next time this all happens again have your dad say "I didn't know he took the car out" and end of story no one get completely screwed.

I just wanted to know if the engine would handle more pressure with new pistons thicker gasket sets

 

Im not in reference to the hp it can support, but more so the pressure.

right around 15psi, its going to debate on blowing or not. You might get lucky and even push up beyond that.

the 2.2 plastic intake mani is 2 pieces. the 2.4 is a solid piece. In theory, the solid should with hold more pressure, since theres no fault line so to speak.

Good luck though!

 

didnt know the 2.4 mani was a one piece. hhhhmmmm

 

How so?

psi is..psi.


10 psi from a turbo, is the same amount of pressure from 10psi from a supercharger.

The only difference is air flow.

But PRESSURE is the same.

If you are saying 1psi of a turbo makes (ex.) 10hp per psi. and 1psi from the supercharger makes say (ex.) 5hp per psi. Your right in the aspect that psi doesnt mean the same hp between the 2.

10psi from a HUGE turbo wont make the same power as 10psi from a baby turbo.

However, pressure wise its all the same.

 

you're correct. pressure wise, its all the same. but it isnt pressure that blows the stock pistons/rods, its power, and the OP was effectively asking how much power the stock bottom end can take

BTW, burrow > irradiate
mass hydras and lings with a little strike force of 12 guardians and 12 mutas and im set to rape anyone

 

You have the same hahn kit as me and I've been running mine at 14 psi.
Last week I turned it down to 13 psi.
Interceptor gauge shows 242 Net hp @ 6350 rpm's

There was a person here who ran the GT2860RS on his 2.2 at it's max. of 25 psi with forged internals using the canned SCT tune that comes with the Garrett Alpha Kit.

Was that you or do you know who this person was?

 

all you guys that are running at 10 psi plus what kind of power you putting down?

 

who the hell did or would do that? I highly doubt that tune would provide the fuel needed at those power levels...what injectors come with that kit anyway? Probably would run out of injector too if they're only 32#ers

 

The kit comes with 39#

I tried to search for the thread where he posted about this but I can't find it

 

I would bet more on the rods and rings. Piston will hole decently... even if it is a puny little thing.

 

agreed. rods break first under power, and the rings are so shitty they'll probably go soon after

 

dawg why didnt you ask me this question....

as soon as i change out my intake manifold im going to bump the boost up to 18-24psi
