Ok to run a MAFia or switch out

[08nastygt]

So my turbo project is almost done. I have a ON3 kit and you have to chose what you want to do for a mass air. On the test car they ran a MAFia but now he's sayin to run a Pmas. What do you guys think I'm only gonna run about 460-470hp this year and next year go more. You have to tap the pipe for your mass air if that makes any difference. Thanks

I don't like your name.. Just sayin'...

I have yet to have a problem with any car running a MAF.ia (always mount them in a logical spot, not where they will get hot or vibrate).

However, that being said I would rather tune a PMAS HPX/SCT BA500 (same thing) in a blow-through setup. This keeps your transient fueling tuning pretty straight forward and is more representative of air temps going in the motor if its a blowthrough setup.

Use the pmas hpx.

Mafia is fine.
Good luck with that shit kit.

Shit kit? I haven't had a problem with the way it fits nor the quality yet. Maybe your thinking of way back when they first started or go on turbo forums. If you talk to anyone who has a kit or has actually seen one they are all happy with it. Idk why people bash Chads kits so badly.

 

[JeremyH]

Hey its cool if you like it, its your car. Nearly all the pieces are knock-off inferior parts.

So I ordered the MAFia, my pipe on the tube to the throttle body is 3in so I should be good to run around 460-470hp don't ya think.

The stock Ford MAF only outputs to 6.5v so you cannot use all the positions the MAF.ia offers. I'll leave it as an exercise using the MAF.ia instructions (on Diablo's website) to figure out what position this is.

Stock MAF in stock housing registers about 40#/min or 1100kg/hr. Scale this by what you discover from researching above and see if this reaches your engine or rear wheel goals.

I know I'm mean for not handing out answers.

Setting 3 or 4, I don't get how I'd figure the power output on a 3in pipe though.

I am always interested in stuff like this.. Take no offense, everyone bashes the lower end kits, but these kits help control pricing and keep everyone on their toes. It may be hard to fathom, but let's assume, that this on3 kit is practically flawless, despite the cheaper WG and BOV. If you can replace the parts you see as inferior and still save money, where is the loss? I will not mention the turbo or intercooler, because you can upgrade to a Master Power turbo (decent units) and though the intercooler my not be as efficient as some, it will probably work fine. I would, however, make sure the IC is clean before installation. The other day, I heard someone say (somewhere) that the stainless tubing would crack or split, this is just ridiculous. I got news, 16ga 304ss tubing is 16ga 304ss tubing. If it conforms to UNS S30400, it is what it is. I also heard someone say that 304ss was not the correct grade for the hotside... ok, yeah, whatever..

This is a thread on MP turbos, for the haters:

No one wants to get their ass handed to them by a guy who is into a kit for ~$15/hp. It is obvious that this kit shares a design similar to another well known kit. I'm interested in your build and it's results, why don't you post your progress and some pictures elsewhere in the forum? You could use the pictures and video section.

These words he speaks are true....

In a 3 inch pipe and the power you are going to run you should be able to use the stock MAF without the MAFIA.

 

[08nastygt]

Natural 1 I started a build thread. I should have waited a little longer before pulling the trigger. I guess I'll have it for insurance though.

 

[Natural1]

Cool, I made the first post in it! I cannot believe that a kit below $2500 is not drawing attention. I always ask questions and perform research before I make a decision about anything.

 

[08nastygt]

Also if I have to tap into a pipe for the mass air the pipe going from the intercooler to the TB will be ok correct? I know the guy above said somewhere cool for the MAFia and not were itll vibrate.

 

[Wes]

For the MAF I would put it in a straight run of pipe and AFTER blowoff/bypass valves. For the kit you have, the pipe pre-throttlebody is a good location.

The MAF.ia on your car will work on position 3. The factory MAF works RELIABLY up to around 6.2v.

* The rest of this is based on sweeping assumptions since I do not know much on your setup, just use this thinking and apply it to what you are doing. *

I'm not sure the exact ID of your tube, but let's assume it is the same as the factory MAF's and at 5v it registers 40#min. If your tube is larger then it can register more flow.

Put the MAF.ia on #3 (6v -> 5v):
40*(1/.59) = 67#/min. So it will now register 67#/min of airflow.

Let's assume 9.5bhp for every #/min of airflow (number pulled from Garett's site): 67*9.5= 636bhp. To the wheels 15% loss: 636*.85=540rwhp.

Now looking at the results logically and not doing blind math, this also makes pretty good sense. Your tuner will be the judge. Does he know how all this works? When he tunes does he do what Diablo tells him to do in the MAF.ia instructions (wrong)? All good questions.

Thank you Wes for that. I'll be asking him some questions to see how he does it. Thanks again

just got my brenspeed tune today for my hellion car. Car keep throwing p0102 codes which is mass air and was running like shit. Took the mafia off and extended the factory wires and car runs like a champ with no codes. brenspeed said about one out of five cars that they tuned that they had to use the mafia worked. so I would say stay away from the mafia if possible.

i have my stock maf in still with a mafia set on 3 and the maf is in a 3"id tube and we just made 707 the other day. so that tells you how far it will go. but i do have the pro-m meter for when we go to 25psi and shoot for at least 850 just turbo and 950-1000 on nitrous
