subiemech85 Posted April 22, 2006 Share Posted April 22, 2006 25+ psi on regular gas, just remove waste gate line no fuel cut experienced no idea how long it will last that way Quote Link to comment Share on other sites More sharing options...

Caboobaroo Posted April 23, 2006 Share Posted April 23, 2006 you're looking about 9-10psi without an intercooler but remember, even though you crank up the boost, means it'll run leaner then it does which means more engine fatigue. More of a risk of blowing your engine sooner. Quote Link to comment Share on other sites More sharing options...
mattyg41383 Posted April 23, 2006 Share Posted April 23, 2006 My experience... stock turbo, top mount saab 900 IC. All at the dragway. Ran 20 or so runs at around 15-17psi no problems. Ran 1 run at about 22psi - headgasket keep in mind this is only 1/4 mile runs. no title, etc. so no street info. Quote Link to comment Share on other sites More sharing options...
jeffast Posted April 23, 2006 Share Posted April 23, 2006 blown bimer ran 25 psi on the street but it killed the engine in like 3-400 miles but it was a fast sob and i mean like rod knocking so bad i can't hear myself think bad Quote Link to comment Share on other sites More sharing options...
desperate Posted April 23, 2006 Author Share Posted April 23, 2006 fresh rebuilt ea82t(new internals, etc), was just trying to find out so i know what to set the mbc for. I know I have to break the motor in, should I run lower boost during break in or turn it up to 8-9 psi like it will be run before I get an intercooler fabb'd up?

jeffast Posted April 24, 2006 Share Posted April 24, 2006 logic says stock(7) boost i would run less if i was breaking in a new engine Quote Link to comment Share on other sites More sharing options...
desperate Posted April 24, 2006 Author Share Posted April 24, 2006 i was planning on running about 5 psi until about 500 miles or so on the rebuild, then turn it up to 7 or 8 and leave it there until i get an intercooler rigged up Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted April 24, 2006 Share Posted April 24, 2006 run stock boost during break in. It'll properly seat the rings like they should be IIRC. Then, once you get it broken in, my advise, since its a fresh rebuild, DON'T crank up the boost until you've gotten an intercooler, larger injectors, and a AFPR to give you more fuel. Ask Tex how much of a pain in the butt it has been for him and his RX...... Quote Link to comment Share on other sites More sharing options...
desperate Posted April 25, 2006 Author Share Posted April 25, 2006 I'm planing on doing an ej22t swap later this year, would it even be worth trying to upgrade the ea motor with an intercooler and those upgrades or should I just save the money from it and put it towards the motor swap?

BoostedBalls Posted April 25, 2006 Share Posted April 25, 2006 I hope you have an extra engine ready to drop in! Put in an intercooler and run stock boost= more power and longevity. Cranking up the boost this time of year on a non-intercooled turbo engine??? WHY??? The intercooler is the HEART of the turbocharged engine!!! Think pressure DENSITY rather than just PRESSURE. Density is what makes power. The intercooler will give you that. I have run the ea-83T over 20 si plenty of times but never without an intercooler.
