Stock Air Cleaner Limit

[TURBOLICKER]

I recently finished my T-Type build with a mild 4.1, head porting, 204/214 cam, 50LB inj.,3" downpipe. If the MAF has the smallest diameter in the intake stream is the stock air cleaner really a limit at say 17-20 PSI? I am looking at the oval opening at the front of the air cleaner that goes to the plastic air duct at the rad support and if this was round it would be 3" in diameter. Don't see how this will affect air flow potential.

The stock air induction has been almost unbelievably quick. A2000rich has posted a lot in the past about the stock air box and mafs. If you aren't well into the 11's you arent at it's limit. I remember the stock AC paper filter flowing more air than any other tested element in the stock air box.

If you are concerned about the inlet being a restriction, you can stretch the opening quite a bit and still get the snorkel to fit on it.

Have a question for you bison on that last statement you made. When you said "If you aren't well into the 11's you aren't at it's limit." For further clarification, do you mean it's not holding you back whatsoever, if you're say a 12.8 car? Does the stock air inlet system still outflow a car that's mid to low 12's? If that is correct, will an aftermarket aluminum 3" inlet tube with the new LS1 80mm plastic maf and filter stuck on the end of the maf at least still let the turbo spool faster though? Or are you completely wasting your time with the hard maf pipes?
I ask this because I want to know if my setup absolutely requires the 3" aluminum maf pipe with 80mm maf and open air filter on it. Would the stock airbox hold me back?

I recently install the maf translator and a lt1 with the intake and K&N and my 87 spools a lot faster and is a basically stock car only bolt ons.

It holds back a stock car once the boost is increased. Things can be done to overcome it and make enough power to run low 11's. Why someone would attempt this in a non rules situation is beyond me.

You know it is much easier to sucker a race with a stock setup than one with a bunch of mods.
Plus running a number with stock appearing stuff I just flat COOL.

Ah. So am I getting this correct, that you need to put out enough power for say a high tens car, to get a stock air box car into the low elevens then? Sort of like forcing the situation a bit? My build was intended to look at stock as possible. So would I be holding myself back with my setup?

Red Armstrong and others have been in the 10's in TSA class using all stock (appearing) parts, no idea on engine internals or boost level....

I'm sure it equates to wild and WILDER.
Still cool when it "appears" stock to me.

I agree they are in the 10's and the cars looks 100% stock...very cool

Building around the limitations of a stock unaltered air box and stock intercooler inlet requires a special build for sure. If rather have to work around/with the air box than to deal with the intercooler inlet. There's a lot that can be done to increase airflow capability if the factory air inlet. It's. It's not about building a high ten combo then putting a stock air cleaner in place and hoping for low 11's. Most can't even run 10's with non stock appearing and any intercooler/air box. Going fast with these parts requires a big strategy and parts that will work with those limitations.

That is true. I was just wanting to see if I could get away with a mid to high 11's build with what I have now, plus a stock air box. It's not lookin' good lol. Thanks Bison.
