possible? if so will dsm 450s be enough? what is the minimum i will need to pull it off?

 

I think many of the guys up at inline pro run up to 16 on stock internals but thats with a 3mm head gasket to lower compression ratio

 

what motor, what tuning, what turbo?

 

ls motor garrett t3t04 no ems yet but i will be using uberdata in the next 2 weeks

 

why 14PSI exactly? You can run 25+PSI on stock internals ....if the ignition isn't there to support it then you won't make power and thus won't break the internals. I've done 18-19 stock internals

 

you will most likely crack your ringlands...

I hope you are kidding

 

I have an LS/Vtec with stock pistons, running 14 psi on a large turbo. Just pulled my blown engine apart. It seems the ringlands couldn't hold up to the task. Built it right the first time and save headaches later.

not really. torque will be high, but like a said if ignition or fueling needs aren't correct (more ignition though) then you won't make the power to break internals.

Heat and cylinder pressures are what break ringlands. What makes 40PSI of air break ringlands when a normal explosion runs in excess of 600PSI. The pressure sure as hell won't be there. The heat from running such excessive retard may burn a valve or worse, but my point is I really hate people insinuate that PSI is the limiting factor and not the real variable at play here. Hell, it's not even horsepower really it's heat and cylinder pressure....period.

I'm not saying everyone should run 25PSI no problem blah blah blah, just trying to make a point . The concentration should be on horsewpower which is a lot more closeley realted to heat and cyclinder pressures then boost is.

 

How much PSI you are running has no effect on your internals. It's how much hp and torque you are making that matters.

I understand that, but with the turbos people use on Hondas any one at 25psi will destroy the motor. Most people read your post as it was worded as in they can run 25psi no problems with a t3/t4. I just hate to see someone take it the wrong way and go boom

how much ponys and torque you suppose to have for a stock internals? the reason why im asking coz i sorta like in the same boat...would 250+whp safe on stock internals?

Depends what engine. I'm guessing that you have a B18C based off of your sig, so in that case, yes there have been alot of B18's rolling around with 300whp on stock blocks.

 

well here is my dilema..... i was sent a 14 psi spring for my Tial wastegate,or at least i think its 14 psi (we ckecked when it opened with a radiator pressure testor and it read between 14 and 15 psi before it opened, which could possibly be at 7 lbs taking into account exhaust backpressure pushing up on the valve but i dont think so , PLEASE CORRECT ME IF IM WRONG!!!!!!!!!!!!!!!!) anyhow the plans were to put the kit on this weekend and lastnight while assembling and looking over the parts i discovered this. if tis will not be safe i will just remove the spring alltogether for a few days until mi get a new one. what do you mean if the fuel and ignition is nao there? what will i need to do to make it "disappear"?

 

ttt

 

Do you know what the bar rating is for the tial wastegate? I own a 0.4 bar and a 0.7 bar and both hold great at their respective pressures.

 

im pretty sure it is .5 bar. thats what i ordered and my friend has the same onne in his brand new TiAL so we dont know. is there anyone who has a .5 bar wastegate that is off the car that they could pressure test realquick?

 

bump

 

up. any one know?

 

.5 bar is roughly the 7psi spring

 

14psi will destroy stock internals on a high compression engine (10:1). blown ringlands on mine with only 9 psi. not sure about the lower compression ratios, maybe you can boost much higher.

 

bump.. good info..

 

isnt the stock ls comp ratio around 9.0-9.2/1? and i would still like to know about the wastegate if any one can test theirs and see when it opens. my .5 bar wastegate opened at 14-15 psi when i tested it. this is my main concern bc we are installing it tomorrow

 

.5 bar is roughly 7psi. 1 bar is 14.7 psi.

Just for the information.
If you ever want to find out conversions - go to google.com

Example: want to know what 2 bar translates to.....
Type in the search bar: "2 bar to psi" , press enter, and your answer will be there.

Example 2: want to know what 45 inches is in millimeters
type in the search bar: " 45 in to mm"
and it'll give you your answer.

Conclusion: Google.com is a great source of information. Haven't tried to do anything like that in the yahoo search bar. I'll just keep google as my home page. Try it out. If you have any questions, just ask.

Saying stuff like that is probably the reason you blew up your motor....hahaha
