Putting Boost Up On Stock Car

[RBTWENY5]

what boost can i run on my car it is stock everything or is this a big no no like for example if i were to put boost up to say 10psi good or bad?

[30three]

search button = friend. probably wouldnt boost a stock engine. at least run a FMIC

[SLY-25T]

i was only running 7 on my standard. then wen i got FMIC and boost controller i turned up to 10/11

[NARTRI]

10psi is fine on stock

[SHWU]

should be fine.

[PIOTREK]

Don't just boost it cause u won't recieve max gains and only strain other components.

U need a cooler and turbo back exhaust at least and probably some sort of induction kit

[PM-R33]

Do a full exhaust first. The car will make more boost pressure by itself as it is taking away a restriction.

Upping the boost on a standard car won't give many gains as there are still large restrictions.

dump/front/catco cat was the best thing i did! really should finnish installing that ebc though

10psi

massive turbo... relax, i believe ur limited anyway due the nature of the stock turbos. other people will be able to elaborate further. basically they crap themselves

The vac line that doesn't connect to anything, Is that the line that the other end connects to the boost controller? Because if the controller has no idea what boost the car is running it wont be able to regulate it.

So you have 3 vac lines coming out of the little black box?

[matho20446]

haha yeah 1 goes to plenum 1 goes to turbo and the other one goes nowere and yeah its not regulateing the boost

[shotter]

you may have one of the vac lines connected the wrong way. Does the box have COM and NC just near where the vac lines connect?

That hose needs to go back into intercooler piping. As stated it controls boost.

you can get an air nipple welded or a screw in type from like repco of sorts.

Im sure this has been discussed many types, search intercooler, nipple.

jacked thread here... soz

But there is already 1 vac line going to the plenum that should be all the controller needs to tell what boost pressure the car is running. Why would you need 2?

[jutto87]

just rip all that crap out and connect one side of the boost controller to the wastegate on the turbo and go to autobahn or repco and grab a little brass bard fitting and screw it in the cross over pipe( will have to drill and tap it first) then plug the other sside of the boost controller onto your bard fitting and hey presto your done. go for a drive and set it at around 10- 11 psi on a stock setup. anymore and well we all know what happens. lol

If you're running standard turbo, dumps, fronts, cai etc then I wouldn't go over 0.7bar
