Icp And 3" Gm Maf

[CVD]

Full 3" IC piping will probably hurt throttle response and torque.

With the GM maf the system probably would have better overall flow, but if you are only pushing 18psi with a 16G, how much of that flow do you need?

[Shane@DBPerformance]

40mm is also smaller than the inducer size of a 14B compressor wheel. 18psi with that restrictor in front of the turbo is not going to flow like a 16G at 18psi would normally be able to. 3" I/C piping is going to be way overkill for that turbo even with if their wasn't a restrictor, but the restrictor is just going to make it even worse. The stock throttle body matches up perfectly with 2.5" OD I/C piping. Most of the piping kits out there are only 2.25" which is more than enough for a 16G.

thanks for all of the response guys. just one thing...I never posted that I was going to run 3" IC pipe. That would be huge for what I need it to do. Just the exhaust will be this size, and this is only because I have it already.

I am planning on going with a 2.25" IC pipe system, probably the same for the intake if I dont end up going the GM route.

Also I would rather run a 14b but no one wants to make a 40mm restrictor for a 44.??mm hole.

3" gm maf = 3" ic piping

How does that math work? Looking at the Dejon Tool UICP for placement of a 3" GM MAF the pipe is only flaired to 3" at that location and only 2.5 for the rest. Is having that GM MAF in there with the rest of the system being smaller still going to be "over kill"?

Ok lets start over. What would you do to your intake/exhaust/fuel systems if you had a 40mm opening on a B16g turbo? Less than $1000 options please.

I would probably run the biggest and least amount of exhaust possible. A hacked 1G MAS or stock 2G MAS. And either 550s with an AFC or possibly just try running a high base fuel pressure with a cheap B&M FPR on the stock 450s.

Walbro 255hp $100
used s-afc $200
aeromotive regulator setup w/ gauge $250
550's, used, $200
that gives us $750
2g mas $50
so we are at 800
3" dp, no cats or mufflers,:)
Should be a tad under 1k, lol.

Thats what I am looking for. Thanks and keep it coming if you have ideas.

aeromotive regulator setup w/ gauge $250 What is this ????

Can I vent the BOV to atmosphere with a 2G MAFS ?

You can vent but your car will still run like shit. It is not the gm maft that lets you vent, it is the translator. The Aeromotive regulator with gauge is an adjustable fuel pressure regulator with a gauge. I have the one at Buschurracing.com. They are nice to have when it comes to tuning.

I would go:
used safc - 200
used 550's - 200
walbro 255 (low pressure) - 100
cheap B&M regualator - 50
catback (used) - 300-350
offroad dp (used) - 200

You would also want a datalogger (100). You could hack your mas if you need to (free).

Stock injectors, rewire fuel pump, no afc, buckle up and let her buck.
