Hey guys and gals. Im trying to achieve an apporximate trap of about 109-110. I have HKS intake, Hallman MBC, Full turbo back, Walbro, with no tune yet. Boost setting is at about 18lbs. What kind of times do you think i could expect? And what else do i need to do to my car to achieve my trap goal? Thanks in advance for your feedback.

 

cams and cam gears and about 20psi of boost with your setup should do it easy.

 

you need a tune for sure

 

tune and more boost

 

+1

 

Cams and cam gears??? No.

EvoGate, your IX should already be trapping 110 easily. You just have a few easy problems to fix:
- A tune is the absolutely most important and powerful mod you can do. You shouldn't even have those other mods without a tune
- You shouldn't be at 18psi. That's 2psi LOWER than stock. Why would you have an MBC only to lower the boost?

You should be running around 23psi on 93oct with a tune and trapping over 110 easily.

 

The boost controller is to prevent the taper that the stock unit produces. As for the boost level, well i just wanted to make sure i was safe, i cant quite get it to 19lbs consistantly so 18 lbs is where she sits. When i go to get a tune im atually going to swap the MBC out with Tru boost unit. I didnt really want the intake because i know that the stock air box is good till you get to about 400hp (i think that is correct) but it was already on the car when i bought it and i couldnt pass up the 18k price tag.

 

i am at 1.2 bar which comes out to 17.x psi.. Why am i not running the factory 20psi..

 

20 PSI is a spike with a taper down to 17 i think.

 

That doesn't make sense - you don't get an MBC just to eliminate taper. You get it to RAISE BOOST and make tons more power with an additional side effect of less taper. It still tapers with an MBC - just not as much. Lowering your boost is just completely baffling. You're robbing yourself of power with a mod you purchased and added. I just don't see why you'd run 18psi when 20.3 is stock for your car. If you can't get it to run 19, then you have a problem and should fix it immediately.

If you got a IX for 18k, then I would be a little worried.

YNGEVO, we already answered you in your own thread - don't thread jack. 20psi is not stock for your your Evo.

 

Right, it doesnt produce as much taper as the stock unit. Thats why i wanted it. Now please forgive me for not mentioning that i do have an autometer guage so who knows i could be running 20 lbs and not know it i have heard bad things about them too. So please, dont be so baffeld. As for the sticker price, yeah i was skeptical too but someone had keyed the car and the guy i got it from didnt want to have it fixed. KBB was 22,500 then and he wanted something new, so i took up payments.

 

Well, my Autometer has always been fine and showed to be about 1psi above a MAP sensor reading. It still doesn't make sense that you wanted an MBC just to somewhat reduce taper (not remove) while lowering boost. Taper is automatically less if you run lower boost anyway, so you're not gaining anything until you run proper boost for a IX, which is at least 23psi on 93oct.

 

Thats the thing, i never wanted to reduce the boost level, im just telling you what im reading.

 

Then turn it up where it belongs, and if it won't go up, find the problem.

 

I did the boostleak test and checked the lines on both the boost controller and boost guage. All checked fine. the only thing i can think is that it reads low. I was only hitting 17 lbs stock.
