If you can keep it at 10, you should be fine. I was running 10 Psi with no issues, stock bottom end and head.

When it went over, I had problems.

Default yes

maybe im lucky, but ive haved strong boost creep for over 4 months now, with no problem. with a 9lb spring i make 9psi at about 3200 rpm and 16psi at about 5500. Yes, it gets lean (about 14/1) at 5k rpm.

Anyway, point of the story is, if you have good gauges you can spot the majority of problems (boost related) before they arise.

P.s i just shift earlier

Holy smokes thats some serious boost creep. 14.x:1 afr's will melt stuff. I know cuz one bad pull tuning my current blower resulted in 13.7:1 up top and melted both my cats, ha.

you drive a 2010 tc correct... this is for a second gen tc 2011-up therefore we have 2 different engines 2 different cars so your post is utterly misguided and should not have been posted in this section please if your reading this do not rely on this as reliable information

Wrongo! Super genius. It doesnt matter if I was driving a boosted Mac truck, that wasn't the point. Gauges! Installing and understanding, oil pressure, vac, afr, and a good thermostat is the only way to understand whats going on under your hood. How do you think professionals ( n tuners) know how much they can run. I don't think they read it off any forum.

Anyway get ur car professionally tuned.

Just saw your sig. How were you able to drop 600 lbs? and how much did you have to compromise

I got my car weighed when I PCS'd to AZ(bone stock). New hood full exhaust system pulled a ____ ton of paneling heat shielding and carpet wheels rotors washer pump and fluid (kept ac) after my sun roof got smashed in by a eBay CF hood I installed a stationary from a spec, engine port job, no tools or spare. A bunch of random little ____ all adds up.

It's always really loud in my car, but on the plus nothing rattles. My new fuel pump is audible but it's not too bad, unless I pull my back seat out (64lbs btw) then its loud as ____. It rides great but some people can't stand the exhaust note inside the cab. I'm use to it, i actually kinda enjoy it because I can tell immedently if something's off (if I'm not eyeing my GAUGES).

thats awesome! I'm looking to shred some weight and what you mentioned sounds like the perfect formula.

I agree with you that no matter if you're turboing a tc1, a mac truck, or whatever that what you mentioned applies. I spend a lot of time reading the tc1 forced induction forms to learn from you guys. Thanks for your input. Gauges are a must.

the question did not ask all of that though yes having guages and being able to read them does help but when your asked whether a tC2 can withstand 10 PSI without rebuilding the engine then you your tc1 experience with your engine being able to withstand so much does not make a matter and yes professionals do use the gauges to know how much to push but as a daily driver you dont want to accidentally ____ something up because someone driving a completely different car said oh it will be fine as long as you look at your gauges

Wow troll, you contradict urself. Plus I never said it'll be fine, what I'm saying is you'll never know till you try. Obviously, you think you know a lot more then you actually do, so I'll explain it to u like a child. All motors very, even if it's the same model of the same year made in the same factory. You're 2ar-fe is completely unique, gaskets have faults, bolts are torqued differently and your ports n valves flow different cfm's. That's why advertised bhp is an estimate. If it turns over and runs they sell it. There for you should'nt expect the same results and limitations as anyone else. Example, let's say from the factory you headgasket sits 1/16ths" off center and the only thing it's effecting is an oil line. Doesnt really hurt anything untill u go turbo and need good oil flow. How do you know your oil pressures off? This isn't a problem too many people are going to run into, say 1 in every 1000 motors have similar problem and 1 in every 1000 of those have a turbo installed, 20000 models sold? so what's the chances you can find accurate numbers you can run, With a problem u don't even know about. Get ur vehicle professionally tuned, they should be able to bump ur psi up untill they see potential problems arising, they dont just load up someone elses tune and send you on your way (although they may use it as a base). Then they'll sit you at what they deem to be safe. They do that using accurate numbers in really time. gauges lol.

But devanb3 is right, don't believe anything you read online.

Give this topic a search. 10lbs is ok on good tune but if your driving the car all the time, your fine with 8lbs on a stock engine. Its been done since 2005 - If it overboosted for some reason, you have room to play with. Tune it for 10lbs and kick it back to 8-9lbs. The car is plenty quick at that. When you have over double the hp, as the stock car, your gears are all wrong. I had a 300hp tC with limited slip and could slam all thru second. It was fun but the turbos have a lot more torque spike (compared to my s/c). Keep the car stock looking w/ the dezod kit and you will fool most people by a lot.

My car's in my sig. Desired WOT afr's are near identical on any motor (11.5-12.0:1). 14.x on anything is no bueno. We just had a local pulley only 04 lightning to scorch a ring landing @ 13.7:1

dude relax, hes just trying to help, he IS right, my 2012 6MT descendant boosted tC runs amazing and right, as long as you know your gauges, and i quote this from one of the best tuners in/around chicago, as well as people who have boosted cars. as long as you know how to read ur gauges youll be fine, when i first boosted my tc, i didnt know how to read my gauges, i didnt even bother looking at em, that was until i blew my motor, my vacuum lines were disconnected and i didnt even know it, spiked to 35+ boost and blew the ____ out of pistons, cracked two of them to the points that they were cracked like a mother f*****, anyone giving any advice is just trying to help, no need to be a ____ about it
