AFM Upgrades

[JayRome]

hey guys, need your ideas on a good AFM upgrade for my Galant GSR. in a few weeks time i'm building a custom intake mani with tuned runners and i really dont want to use the orig one a lil restrictive for my tastes. any one with wiring diagrams/schematics for AFM conversion?????

I'm nearly certain the non-turbo's have a different plug set to the turbos.

Upgrading the AFM won't give you much in an N/A setup. You might gain a kilowatt from a CAI and pod but I'm not sure exactly what you're attempting to accomplish other than getting rid of the giant can?

 

[JayRome]

ahahaha yer giant can is good for holding cold air, and i'm already running a force fed CAI, was thinking of running the V6 Magna 6A engine AFM its larger diam to the galant ones and might flow better. but with the new intake mani and exhaust comin along, i'm wanting the intake to flow freely...... any other ideas?

trying to copy the AMG galant 4g63 n/a with 10:1 comp, but no one has a web site on specs or any info on the engine!!!!!

 

[Entaran]

Apart from 10:1 comp, all the AMG engine features is a cyclone inlet manifold. That's about the end of it.

And a slightly more aggressive tuning map.

As for your intake, in N/A form, it flows about three times as much as your engine can use stock. Hence the near complete lack of gains.

Welcome to go ahead with it tho, nobodies going to stop you

 

[JayRome]

ahahah yer meh, its free and i have way too much time on my hands soo i'm goin to try and figure out how much power i can pull out of this n/a 4g before i shove a SC14 down its throte, hence the custom intake mani to fit the supercharger under it so its hidden from view!! kinda not fair but.... like i care? thus why i am asking for advice for a high flowing AFM for no restrictions...... any ideas welcome on this?

 

[Entaran]

e3 item. You'll need a chipped ecu and have to make a wiring harness.

Also a 98-ish model magna afm works as well.

Again, need chip and wiring harness.



Otherwise go for standalone management.

You can also extract a fair bit of power playing with adjustable cam gears. Put in a set of vr4 injectors (450cc instead of 390cc gsr injectors) and scrap your redline. I had my old GSR past 9500 rpm a couple of times. Not that it liked it. But with the correct screwing with adjustable gears you could rev it to 8k or so.

Are u serious?
Gsr Gaalnt?
It would surely valvebounce...drivetrain harmonic destruction!!!

If you are going to forced induction then you're best bet is aftermarket management and then you can get rid of the AFM completely and go to a pod filter and MAP sensor...

Yep. 100% guarantee you i've had it past 9500 rpm on at least 3 occasions. The rev limiter in it never worked (ECU fault) and I usually don't pay overly much attention to my tacho. Saw it bouncing off the little plastic stopper thingy past 9000 on a number of occasions.

Those engines are hardcore man. They don't die

trying to find a self learning chip for our cars, but pigy back system should do the job. as for goin past 9grand RPM ah........ i'd rather not but his right the gsr 4g63 does pass its red line and keeps goin like it doesnt have a limiter, i have held my engine at 6-7grand thrashing it through the long back streets of greenvale and it loves it but 9grand and it sounds like its goin to blow.............. and the SC14 will only go up to 7grand then max out. gsr stock ecu should hack a fair amount of PSI before it has no idea wat to do and shit it self any way, soo a supercharger with a switch should do the trick.
other ideas welcome?.........

Autospeed did an article on the AMG Galant. it had a bit more than just the high comp ratio and the cyclone manifold.

The AMG had different pistons (which raised the compression ratio from 9:1 to 10.4:1), piston oil jets, aggressive camshafts, titanium valve springs, hollow rocker arms, a high-flow exhaust manifold and muffler, dual-stage Cyclone intake manifold and revised engine management. running on premium unleaded the AMG Galant pumped out 125kW at 6750 rpm and 191Nm at 5000 rpm, and the torque held strong to the 8000rpm rev limiter.

short ratio gearbox, a larger diameter clutch and a beefier passenger side driveshaft.

0 - 100km/h in about 8.5secs unsure of quarter mile time.
