What is the stock boost PSI for an IX...I've tried searching but cannot find a consistent answer...mostly from people who have had their cars tuned...I have not

My mods:
3" Weapon-R downpipe, Perrin High-flow Cat, and Agency Power Ti- exhaust
Injen CAI and IC piping
TurboXS MBC

All I want is a basic baseline so I know what is exactly normal for PSI...I want to know what is too high for 93 octane and whatnot...please let me know

 

Search harder. It's been answered hundreds and hundreds of times. 06s are the same as 05s with stock boost, and even the 03-04s are within 1psi, so you don't have to only look for this info related to IXs...

PS. If I was asked for the worst way to spend money when modding a IX, it would be your mod list plus an HKS SSQV.

hey, i was told a few days ago 20psi then 16 to redline...i have the same cai and ic piping as you from injen so far....my boost gauge only reads 18ish then 15 to redline..i think the boost gauge is screwed up...but it varies

 

According to the Evo brochure: 20.16 psi at 3500 RPM WOT, dropping to 16.10 psi at 6500 RPM WOT. On my DEFI gauge (car is stock except for a drop in panel) the highest consistent reading I have seen is just a tad over 1.4 bars, which is just over 20.5 psi.

 

That is correct, but not all run the same exact boost. Of course, in your case, having ill-advised mods doesn't help the situation.

It's kind of amazing that you did the cardinal sin of Evo modding by doing the $400 Injen Intake and $250 HKS SSQV, both of which hurt your car in stock form, one of which is not as good as your stock piece, but you plan to get the best stg1 package in the future! Smart move on the last part, heh.

 

Why is the Injen Intake package a bad mod?? I've heard you loose about 10lbs of torque with an high-flow intake, but I've also heard that you can make up for that with a good tune...what other reasons? Oh and how would you suggest I mod my car...you give advice without really giving advice

 

Drop in filter K&N and stock blow off valve go a long way 350 whp with no probs

 

I give lots of advice - you just aren't good at searching (or just not good at reading my sig).

It's a bad mod, because you aren't tuned for it, and it gives more bling than power. Spending $400 on a custom flash is 10x more useful than spending $400 on a shiny intake/uicp. One gives you lots of power - the other gives you lots of noise. An expensive TI cat-back without even the benefit of a major brand name like HKS, a restrictive hi-flow cat, and the worst MBC on the market really top it off nicely.

 

Wow...thanks for the advice...still think you're an *** though

 

LOL

 

You are completely right. Warr does know his stuff but can be an *** most of the time. Alot of people find this site after they buy their evo and start modding so best thing you can do is get a tune and just search on here for the next best mods. The intake isnt a bad choice just expensive i have it and have had no problems with it but you do need a tune with it to make any power. Also the boost controller isnt the number one choice on here but if it works then it works, Most people use hallman or forge.

Thanks man...appreciate it. The boost controller is not expensive...I'll probably buy a different brand at one point...just didn't know why it was a bad product...still don't know why it's a bad product...ah and as for the tune...will be tuning very soon...

 

To be honest with you man if the boost controller is working fine for you i say keep it theres no reason to buy something else that is going to do the exact same thing. Its not a bad product but its just not used by alot of evo owners they prefer the hallman or the forge. And warr is obsessed with forged products so thats why he is against that boost controller but like i said if it works for you then keep it.

If it helps any my stock IX makes 18 psi peak tappering down to 15-16 psi by redline......sometimes I get a 19-20 psi spike in higher gears(more load)

 

Do a search under evo9girl or myself. I posted the stock boost from whenever I got my Evo 9 stock. Ours was like 19 peak and tapering to 16psi.

When you do a search look under threads started by the originator.
