moving the maf

[fred slawson]

Will moving the maf further from the throttle body negatively impact engine management in anyway? I'm thinking of what Nocutt did with his in order to put some extra injectors and water/alchol injection between the maf and throttle body.

Most tuners and/or DIY'er especially with true MAF sensors run a suck thru setup. eg turbobuicks. A blow thru can be ran but you would have to recalibrate the MAF, but then again you cannot spray into the MAF...IMO a suck thru is the best setup...especially for guys who want to use an AIC or h20/alky injtn. The one problem associated with moving the MAF is throttle response will be affected. Mind you, NOT @ stop-WOT blast or highway cruise...which is all that matters [img]tongue.gif[/img]

Most systems have the MAF downstream of the airfilter and upstream of the blower. Of course this is a problem for 3.8 because of where the MAF is integrally located. I discussed the problem with Vortech support and they suggested moving it or we will see some rough idling problems due to "turbulance" caused by the blower. I am soon to get my Vortech running and am leaving the MAF installed where it is unless I have a problem. I also have no intentions of running any extra injection, just about 8lbs of air.

Thanks for the replies. I do plan on boosting beyond 8psi so I think I will have to move the MAF to the draw thru position. Once again Nocutt your a big help.

There are ways of combating the "turbulence" the blower will create...I am curious what are your plans for fuel & Igntn management?

What are guys doing about a MAF when they are running two turbos?

It depends! Guys with a true MAF and TTs do a blow thru...boost or rather air flow can still be read by the MAF up to a point, this point can also be recalibrated via a PCM reprogram. Then their are those who convert to MAP and use an aftermarket PCM. The true TTs which come from the factory have two true MAFs placed before the turbo...if they use a MAF!!

Cool, so many recipes for fun. Got to love it. Turbo link2 is looking more inviting all the time.
