Got a question. will the 3 bar map sensor upgrade allo0w to run a solid 25psi without limp mode?

 

u can do that with the 2.5 bar. but i wouldnt run that much, ur just asking for piston failure like some other guys

 

piston failure at 25psi?.....

 

Yep, long hard pulls at >24 psi generates too much heat for the piston ring end gap. The rings expand, gouge into the cyl walls and pop the ring lands off of #1 or #4 piston.

I spike 25, hold 24 to 4500 and taper to 16 psi @ 7k.

The HPT over TF tune will let you boost that long and hard if you wish. I prefer not to overspool the turbo drastically at higher rpms.

 

anyone know where to buy the 3 bar map sensors?
i've been searching and couldnt find em

 

interesting. subd

 

u need the gms1 tune for them to work

 

Im running 2 temp levels colder plugs which greatly decrease combustion temps

 

sheldon im tuned with trifecta, vince is awsome.. at 25 psi it runs strong and holds 25psi all day through every gear and no problems.. ive nvr heard of any kinds of piston failure.

 

then you're not paying attention

 

Ya, I just made it up. :-\

Here's one thread, there are others.

>24 psi is asking for it over time. A GM Engineer posted info here several months ago.

Doesn't matter if it's HP Tuned or Trifecta or whoever. Too much heat in the cyl will blow the ring lands as I described. Use the search function.

 

Get an upgraded ic will greatly reduce cyl temps at higher boost levels

 

so will meth / water injection

 

Plugs help too and i got them and i also got intercooler.

 

or you could not use such a dinky sized turbo

 

All of u that think magic and supporting mods will prevent ring failure at 25 psi+ are not being very realistic

 

Just run 22 PSI. Its like screwing a pretty hot girl that doesnt have AIDS, versus 25+ PSI which is like screwing a hot ass sketchy girl that u are unsure what she has and once you have AIDS your fucked and wished you would have settled for the other less sketchy chick.

 

how are people not getting owned by infiniboost lol. isnt that **** like 30psi. my 22.5 psi tune is more then enough to make me happy. but seriously get a turbo that flows more cfm and you wont have to worry about it

 

boost isnt everything i have seen alot of balts on 22psi butt rape the crap out of infiniboost balts
