MAF 95 Cobra Turbo build < HERE!

Low budjet Turbo build 1995 Mustang Cobra
5.0

I have everything on the car exept charge pipes, due to the location of the turbo, I cannot do draw through like I wanted!

Here is what I have and my plans:

T70 turbo MP
FMU
Stock injectors
(planning on using stock MAF)
aermotive Fuel press reg
219 lpg pump
38mm gate
1g DSM BOV

I am going to pull the spout and lock timign at 18* and run 41 psi of fuel pressure.

Well, ran into a problem with the turbo being located right behind the passanger headlight, I am not able to get an pipe on it and run stock maf..
SO

Can I use the stock meter in blow through configuration ?
if not, is there any MAF's I can use with 24# injectors that is redily avalible and can be used in a blow through setup?

ditch the FMU, get some 42s and a PMAS pro tube MAF !!

try to have NO bends before or after the MAF for atleast 6in.

its as low budget as you can without being "unsafe"..

I have $450 into my maf/42s on a budget it might seem high but its well worth it !! I can run stock timing with spout IN, car idles. starts and drives exactly like stock.

same here, i paid $200 for my brand new 42's and $115 or so for my PMAS blow through, i also have an aeromotive RR fuel pressure regulator


an FMU and stock injectors wont be able to even keep up, you'll run out of fuel in no time.... on top of that, get rid of the DSM BOV and get a "tial" from www.evansperformance.net

Im pretty sure you need a chip/tune to use the 05 maf and no one GOOD will tune with a FMU and small injectors.

You need 42 lbs injectors and good blow thru MAF as said before
stock 24's are never going to cut the mustard.

Boosted engines require much more fuel per hp than an N/A engine.

Going cheap and trying to cut corners on the fuel and tune is a good way to
blow up your engine.

a lot more work than selling both of the MAF's you have and getting the properly sized one and a set of injectors

El_Diablo is correct !!!

its going to cost you a SCT chip and a dyno tune which is more then a new pmas and used 42s.. NOT to mention nobody woth a crap will tune a turbo car with less then 42s.... most prefer 60s

ok, so if I get a set of 42# injectors and the maf that is calibrated to them im fine without a chip and tune for now? I mean, the car will run and drive( not saying this is correct)

So I think im going to do the 76mm C&L and 42# injectors run 10 psi back down timign and play with fuel pressure.

ok done deal i know what I need, 42# ijectors, if anyone has em or know where they are list here please!

and I need a pro-M cal for 42's for my 95 for blow through

found a new pro-m meter for 250 bux from atomic, i need a deal on injectors and im set!!!

Might as well do it somewhat right and run more boost, like say 10 psi? 10 psi with 42's 219 pump, aermotive fuel reg and 10* of timning we should do like 430 to the wheels

it's confirmed, I bought 42# injectors and Pro-M MAF blow through!

Now, when they come, drop em in and it's play time!

Wonder what kinda boost I can do with this setup? Ill have to watch the good old wideband.

FMU, TRASH.

pmas,42s and stock timing on a stock motor I run 10 psi and have pushed it to 14psi on pump gas. NO chip,tune or wideband.. I used a cheap narrowband and pulled plugs, 2 years no issuse

Set timing low to begin with and gradually bump it up making little
pulls and listening for detonation.

As for fuel just make sure your a/f ratio is at 10.5 at WOT under boost.
Do NOT use a "cheap narrow band" a/f sensor. might as well just stick your
nose in tail pipe and smell for right mixture if go that route.

You really need a dyno tune. People running boosted motors on N/A fuel curves
are asking for a blown engine and melted pistons.


You've been warned.

red89coupe, did you just listed to what he said? no chip no tune.

I have an AEM wideband on the car now
I have ARP head studs
I have 219lpg pump
Aermotive FPR
I have 42# injectors and a pro-M MAF coming

I will do 10 psi on 93 octain, with 18* locked timing- or stock timing which is 10* ?

It's amazing how many people will do something stupid because someone else
did it too.

Last time:
N/A fuel curves will never supply the correct amount of fuel for a boosted engine.
It will not make as much power as it should and you run a serious risk of nuking your engine.

The extra fuel supplied to a boosted engine is for cooling and detonation protection.
With the extra heat and pressures from forcing more oxygen into the engine
you need this extra cooling to keep from melting pistons and valves.

Have fun.

LMAO at the narrowband comment.. Im not saying they are good by any means just what I used and its helped me!!! he has a wideband anyway...not like I told him sell it and go narrow band lol Oh and believe it or not that CHEAP narrow band SAVED my motor, when my fuel pump decided to take a dump (only put out 20psi) I seen it on the gauge before the damage was done.

pulling plugs has been done for YEARS. If you know how to read them, yes its a Pain but its free lol

I been asking for 2 years/15k miles and 75+ drag passes and have yet to get a blown gasket or melted piston, but then again I launch with FULL boost with slicks on a 7.5 rear end too, Im just crazy like that I guess...lol or lucky Im SURE Im NOT the only one running NO tune/chip I couldnt come up with that all on my own lol I HAD to of seen it done first !!!!

IF my car was lean, did NOT idle/drive PERFECT, would I have it tuned.. YES !!

I bet your EGT's are somewhere between molten steel and the surface of
the sun too.


100 people jump off a cliff
1 of them doesnt break his neck
Doesnt make it a safe jump

Just saying

He wants to risk it, its his neck I guess.

LMFAO, you very well may be right but so far it has worked FOR ME
could I pick up more power from a chip/tune?? Im sure of it !!

NO, now if 99 didnt break their necks then yes lol lol

Is it less of a "risk" then a FMU and 19s? lol
some people dont have deep pockets, you cant expect everyone to run out and get the beast stuff, now IF he said a deep pocket build and not low budget then hell yeah.... 60s, a SCT chip and sct MAF.. have Bob Kurgan tune it .. and on and on and on

So the car started tonight, semed to idle ok. No leaks, fuel pressure was fine.

I still have minor things to do, so i didnt drive the car just yet....

One thing I was a little in doubt about, was the oil prressure. What is stock pressure cold at ? I think before I was at 60 fully cold. I am not 40 fully cold, however, I did do oil filter relocation, and I DID tap into the same line that the oil pressure gauge is used for oil feed on turbo. Might these have any affect ont he little presssure drop ?

So now I need to go get plugs for boost, still trying to figure out what kinda I need for my eldebrock heads.

This thread reminds me of mine. Do a search for my name and you will find damn near the same posts and a lot more. What fuel pump is the 219lph? I run the 04 Focus svt pump (217lph) and I am switching over to dual Bosch "909"s (0580254909) inlines. As far as injectors go you can have Fuel Injector Connection clean, test and modify stock injectors to go from 19s to 50s for $25 each.


Also go read/research on http://www.theturboforums.com/smf/index.php
