Air to Air or Air to Water?

Hmm, I didnt know it was possible to use a 99-up MAF... I like the PMS even though its limiting at times because I am always changing something and dont want to do the whole $600/tune thing over and over again. I cant afford it.
 
Well who charges $600 ? thats ludacris. You can use any ford MAF. With a blower though you will need a 3inch pipe and a 99-up maf and a modified PCM transfer function. Also you will need a MAFia or some sort of MAF signal manipulator.

I wont name names but its a reputable shop... very knowledgeable in what they do too, i didnt mind paying it at the time (6+ years ago) but dont have that kind of cash anymore.

anyway, I wonder if this is the way to go or to just purchase a blow through tube MAF from PMAS or something. cost wise it would make more sense.

thanks for the help.

a 99-up gt maf should cost about $50 at the Junkyard. I have the MAf standoff block there are $40. Get a MAFIA. All of those aftermarket MAF's have calibration issues. The other option is the abaco Maf at anderson ford motorsports.

Here are some pics of the new blow through set up, sry it took so long.

here is the old set up:
Draw through, recirculating bypass

The new:
You can see the blow through set up in the middle of the charge pipe. And the new power custom pipe

Its hard to see but the bypass is on this pipe infront of the crank pulley

thanks for the pics!

the issue I thought was going to keep me from going to a 99+ MAF was that they are 6 wire and stock fox is (i think) 4 pin. I knwo you can get 6 to 4 pin harness adapters but then why use a 6 pin MAF if youre only using a 4 pin anyway? do the other 2 pins not anything to do with data?
 
seems easier to just use the 6pin maf. the IAT is better off in the intake pipe anyways.

is that what the other 2 wires on the 99+ MAF are for then? I still use the IAT in the lower intake (#5 runner).

That DBX meter looks too good to be true, I want to get one but im not waiting another month or more... they havent even started shipping yet and there is at least a month lead time after that.

The extra 2 pins are the integrated IAT, which you don't need. An external IAT is better for a boosted car to prevent heat soak issues.

The two IAT terminals are the gray wires.
 
Just to add my $0.02 to the mixture...

I've had great success with Air to Air coolers on street cars with an added water injection setup. I've seen temps WELL below ambient with this setup.
 
thanks for the help, maybe in the future ill add a meth injection kit.

my next question is about intercoolers. Ive read a lot of pipe sizes but cant find much about intercooler sizing. Do you size it based on the blower CFM? if so I cant find many rated at over 1000CFM.

Also, im on the fence between 2.5 and 3" piping. according to the calculations in just about in between the 2.

thanks

Pressure drop is the key thing to focus on with an intercooler.

You will want 3" piping for sure and a 1000 cfm intercooler will work very well for you, and will allow you to expand with that Vortech V2.
 
well the v2 I have now flows up to 1000cfm but the blower im upgrading to flows 1150cfm. should I go bigger? Even some of the huge intercoolers ive found (ones that likely wont even fit) dont flow 1000cfm.

whats a good pressure drop figure? ~0.2psi at 15 psi of boost and 2-3 psi at 30psi of boost?
 
the blower is off to vortech to be upgraded to the new SI trim so I need to make headway on the intercooler and piping.

can anyone point me in the right direction with intercoolers? Im not sure what to look for.

thanks
 
I would go 3inch. Your not going to loss anything in terms of power over it and the added surface area "if the pipe are aluminum" will help disapate heat. 3inch gets my nod.
 
after doing the calculations 3" piping is the best choice being that it puts me at about mach 0.27 air velocity where Mach 0.4 is the point where velocity begins to gain too much turbulence and heat to be beneficial.

so now I have to find an intercooler, do you size them based upon HP, CFM the blower flows, the largest you can fit, etc? I know I want a low pressure drop and high efficiency but how do you actually figure sizing?

thanks,
adam
 
As big as you can fit. If you can't fit the size you need at a minimum make room.

OK thanks. Now, Ive been looking for same side inlet/outlet verticle flow intercooler to keep the piping on the passenger side but have been thinking of flipping the intake around so the throttle body is on the drivers side and using a horizontal flow intercooler. I know the vertical flow intercoolers generally have the least amount of pressure drop and flow quite a bit more than a same size horizontal flow.

which would you choose? I know there are a lot of larger horizontal intercoolers out there than there are vertical so that may be the route I go.

thanks
