I just got back from a couple of boost runs. Hit the first corner and I line up with a new 03 M3. We both hit it for like 5-7 secs and he stopped. Gave me the thumbs up and he made a Uturn and went about his business. I like this stock crappy 3.60. My tires dont break loose. By time the car starts to pull I am going fast enough to prevent that. I told my brother monitor that boost gauge for me. He said 7PSI. I was yeah right what ever. I slowed down on this long strip. Looked down briefly and sure enough 7PSI and I did not even redline it. I was about 5600RPMS when I looked down. I am looking forward to 8-9PSI with my CAI that I am going to make. Lets see if I can get that. I wish I could install my digital boost controller to take a picture of that


OOH boy I love this little daily driver. Is awesome

i got a filter f/s if you need it for the cai

Any video's of sleepy in action?

I don't have a SC, but 7psi strikes me as high for the 3.60 pulley, no?

congrats and good luck with your new project.. let me know when you set up your boost control i need to do that also..

thats installed on my turbo maxima. I am not going to pull that out. I had someone else install that for me. He also walked me thru the vacuum connections.


7PSI is a bit too high for a 3.60. I dont know whats the deal with that. Ill try to film it.

I got to show you guys how ugly this max looks like. I am sure that M3 driver was like WTF dont consider that a race but we were neck and neck and he cut it off. I forgot to bring the camera with me. I ll start filming as soon as I get the CAI in there.

Brett thanks for the offer, I have a new filter that has been sitting in the closet for like 5 months.

Maybe the custom piping is less restrictive than the stillen pipes.

7psi is about what I got with the 3.62" pully...maybe +/- .5 psi.

Maybe a little gauge error? My Autometer boost gauge sits at 1 psi with the engine off.

Mine's dead-on zero with the engine off. That doesn't mean it isn't off under boost though...

I dont have a autometer anymore, about to smash that crap with a sledge hammer its not good. My brother brought a brand new Apexi and he installed that last night. Your right 3.62 not 3.60

Remember its been cold as shi!t lately. So colder air will be denser and pack more. So you can get 1psi more than what its rated at.

Dixit

i hit about 8-9lbs with the stillen pulley that came with the kit so its very possible, even though i have a different b.o.v setup to hold the boost... my brother in law lives in georgia, may have to take a ride and see you.. its easier if you saw my setup in person instead of trying to explain it in writing. also i have some serious comp going on and i wouldnt want to give them the edge by posting it... i know for a fact that you are happy. smooth strong power thats what counts..

Maybe you can get 20 psi on the stillen supercharger............

got an extra bracket?

ha? .............

11PSI


slimer, why dont you start your own plate production

20 lbs is obtainable, but very expensive.. i'm 3/4 there just waiting for my spare engine to be completed before i test it out. very low compression thats all i can say for now..lets just say im the test dummy
for this project...

I dont doubt anything w/ a built motor anything is possible. I was just messing with spanish rice.

I don't think a Vortech blower will be able to produce 20psi in our application.

Would be fun though!

20psi is WAY past the centrifugal rate on the V1 or V2. I dont see that as happening, unless there is an new V trim out that can handle it.

Dixit

Vortech's product specs state that the V2-SQ can flow 1000CFM at 20psi at 50k RPM. However, nobody has gotten close to 20psi, despite going over 50k RPM. The 700CFM filters that we're using may not help that that high of a speed...but not the 6 or 7psi that we're missing 20psi by.

You're right, I don't see it happening.

Jay - stop by Grand...I'll see if I can make you a CAI

I was just playing, the highest anyone has gotten is 14 psi right?

I work this weekend, the whole weekend. Ill see if I can stop by on Monday

i haven't reached 20lbs yet either. trying very hard though.. alright i might blow out a few things but **** happens.. but the vortech can handle it for short bursts. REMEMBER I SAID TEST DUMMY...

The only way to get higher boost would be a really, tiny pulley right

you got it



The Apexi guage in my turbo maxima reads 19 HGs. On the digitial boost controller it reads 20-21 HGs. So that means the Apexi gauge is right on.

What does HG mean?

How do they get so many pounds of boost on 5.0's?

HG is vacuum. Mustangs? Any car can do it as long the engine is built to handle it.

Dixit

I got bombed in offtopic by some mustang id!ot who thought I was fresh out of the porch. he said they dont make a 6PSI pulley yeah what ever

tell him after you smoke him, to pulley on your six pound c--k

Here is some pressure unit conversion information.

1 Bar equals 14.5 psi.
which equals 750 torr,
which equals 750mm Hg, (millimeters of mercury in a Torricelli Barometer
which equals 29.5275 inches of mercury,
which equals 100,000 Pascals, or 100 kPa, named after the French scientist Blaise Pascal.

As mentioned, A pressure equivalent to that exerted by exactly 760mm of mercury at exactly 0 degrees Celsius, under standard gravity is defined to be 1 atmosphere.

1 atmosphere equals 14.70 psi (pounds per square inch),
which equals 1.013 Bar,
which equals 760 mm of Hg,
which equals 29.9212 in Hg,
which equals 406.8 inches of water.

you need to be a scientist throwing those types of calculations around


Went out on a drive w/my new CAI setup and hit 8PSI boy I guess no need for the 3.125 pulley then.

Damn not bad. What mods do you have beside the SC? How does the car look like from the outside?
