Does 10 psi really feel different??

[gboromsp]

Right now I've got a full turboback, aem cai, and ion fmic, running stock boost. It feels quick but not really. So my question is by turning up the boost to about 10 or 11 psi will it feel a lot different or not really? The turboback made a difference, esp. in the upper rpm range. I just want more speed now.

do it and then come back and write what you think.

you WILL notice a huge difference. Try it.

I'm just not crazy on the strung out feel it can give the car (more spazzy than before)

[MazdaSP]

eh i say you will only feel the difference if the temperture there is below 50 degrees, its getting to be around the high 80s hear in oklahoma, and still a long summer to go for my overheating msp

It'll definately be faster until the wastegate opens up and screws the flow up in the stock "S-pipe". Then you're back to almost where you were before. That's why we need a separator in the "s-pipe" for the wastegate and the turbine.

i would be more worried about the worst a/f ratios/ power curves ive ever seen on a turbo car(aka the msp) at 10psi.

[mazdaspeed75]

I wouldnt say that mine were 12.2 at 10 psi stayed that way to redline in 4th gear . Yea 10 psi feels good . I dont run that all the time but it does feel good.

[BOOSTR]

No doubt, try some more and you'll feel even better. Especially if you have added the right mods. I have no launch issues or driveability issues running more psi than stock. Just don't go crazy because the rod bolts are not made for massive amounts of repeated overboost.

Run a 2-STAGE controller for maximum boosting enjoyment! Our T25 spools up quickly and will launch well at the stock boost setting. Hit the switch when shifting to a higher gear and hold on.

I cannot speak for all MSP's as no two are alike; but my MSP loves the boost.

(werd) 10psi feels good...I drove CustomMSP's car @ 10psi...felt REAL good. Except for the fact that if you punch it in 1st, you don't get any traction :)

[Swerny]

You have the supporting mods to at least try it, so I say go ahead and see for yourself.
Congrats on showing restraint and getting the big mods first before dialing up the boost, you're a better man than me!(spin)

I just want more speed now. you will be able to tell the difference, but i must warn you..once you go 10-11psi you won't want to go back down and 13-14psi is only another 1/4 turn. i went 14psi for a couple of days, the msp is extremely quick @ 14psi but for now 12psi is just as good. at 12psi you'll find yourself looking to get next to a v8..oh and the look on there face when they can't pull away from you...you've got the mods..give it a try.

It's fun. You won't want to go back. :)

Someone has his car dynoed with similar mods as you and it only made like 7 whp dufference between 7 psi and 10 psi.

[mspeedpro]

wut is ur car boosting at stock?? every psi feels so much better-- its like heroine

[gboromsp]

My car is running 6 lbs right now. I plan on going to 10 lbs, but I don't want anymore than that. That is until I get standalone, and build the motor I have sitting in the garage with all forged internals.

lol i hear you man....its better then heroin....
its so damn addictive, its like a night and day difference for my car,
i would only go back for a day then turn it back up just to realize the difference all over again....

[mspeedpro]

haha ya im constantly readjusting. its like a little devil and angel on my shoulder... at differant temperatures and situations, my conscionse (sp) makes adjust my boost, the ladies call for 10+

[mazdaspeed75]

Someone has his car dynoed with similar mods as you and it only made like 7 whp dufference between 7 psi and 10 psi. That was 505zoom and we both think it was maybe the ecu or something because i dynoed at 9 pis and put 186 then went to 10 psi and got 201whp so who knows what was goingon them days with the ecu . I promise 10 psi is alot faster then 7psi. Ive been reajusting today to launch at 7 and then hit it at 10. I cant stand it to be at 7 psi it feels so slow now. But that is what iam goingt to try at the track to get better times .

[goku4658]

i am such a loser, since stock boost is still fun for me, hehe

[marashka]

i am such a loser, since stock boost is still fun for me, hehei kept mine stock for about 5 months, but then i tried the MBC, and been hooked ever since......

[goku4658]

hmmm what did u up it to first? like did you go alil bit at a time? or just in leaps?

when i added DP it went up 1 psi by utself to 7. when i added mbc i went straight to 9, and will be running 10-11 as soon as i get better intercooler.

[KyRaceFan]

10psi is the best mod ive done yet. I get exhaust on tomorrow, but i still think 10psi will be the best gain. :)

[jurgs01]

I had 10 psi, and had just turned it back down to 7 before I wrecked it. You definately notice it when you turn it up, but you really notice the difference when you turn it back down. It's night and day. You get a really good boost at 3-4000 rpm in 3rd gear. That is so worth the price of the MBC.

[AGR]

I've been at about 9.5psi for over a year. I love it. It's perfect for me. And; I don't have any other wildman shit on mine. Just the boost controller, and a K&N drop in.

[KyRaceFan]

Greg, youre hard.

That is all.

Jeff; I am an honest guy, and you know it! (thumb)

Oh!

I LOVE MY MAZDASPEED!!!!!! (k) (k) (k)

[MJG]

Like Torque222 said, Once you go up you won't come down.... 14psi all day ,and honestly its all about the way you drive.... besides with a full turbo back exhaust your car should breathe really well... I only have a catback system and its fine. The full exhaust is next on list if any.. Good Luck and Enjoy!!! MJG

[mazdaspeed75]

Just got done retunning my profec b. Let me tell you, I think when i go back to the track this is really going to help. Got it set for 71/2 psi for low and 10 psi for high and If i do it right i have asick launch now. I was practicing at redlights and man this is going to help because i had very liltle wheelspin and i hit the high boost at the end of 1st and that bitch was gone. It was really crazy how much this helped, if you havent tried this i would recomend it , it is kinda tricky because i dont have the remote switch and have to push it on the controller, but i got it down now.

so 9 psi = 186 whp, 10 psi = 201 whp? wow! what mods do you have?
