PSi?

yongsooSTi · 03-12-2008, 06:31 PM

I was wondering what PSi i should be or could be pushing being safe on a stock block..I have:

Walrbo 255 Fuelpump
Intake Elbow
K&N drop-in Filter
Invidia Catless DP 3"
HKS Carbon Ti Catback
Will be running 91 Octane

I will be getting a protune in a week so i just wanted to see what the most i could get out of it. Thanks guys

On 91 octane, probably not more than 19psi.

you're not going to see any gains above 19-20psi on the stock turbo anyways.

yongsooSTi · 03-13-2008, 06:16 AM

So i can push 20 and not have to worry about my engine having any problems correct?

nhat · 03-13-2008, 06:19 AM

yes, the motor can handle it...but it isn't advisable to spool the stock turbo any higher than 20psi.

damn, having 91 must suck

yongsooSTi · 03-13-2008, 02:44 PM

20 psi it is then i guess...

Has anyone heard of EDO Performance and are they any good?

Yes it does. Why don't you rub some more salt in the wound?

Yes, Edo Performance has many positive reviews with people on this board.

you mean people have to actually drive on 91!? i thought that octane rating was just an urban legend... i thought everyone has 93

hehe, im evil

importfanatic17 · 03-13-2008, 02:55 PM

You guys suck. At least we can make our power and think "man, I'd be so much faster with 93". Haha

yongsooSTi · 03-13-2008, 04:10 PM

Thanks for all the help guys. I should be getting my tune on the 21st ill let you guys know how it goes.

***Szumita*** · 03-13-2008, 04:19 PM

what really sucks, is if you have 91 and have salted roads. lol

it's all in the tune.
you can blow a block on a crap tune at 14psi, or drive it forever on a good tune at 19psi...

just tell your tuner what you want out of the tune, and let him figure out how to do it. wether it's 17 psi or 20 psi.. it should not matter. there is a point where adding more boost will not get you more power.
