JET releases N* Performance!

Is this too good to be true? I know about making dumb posts and such about Northstar performance mods, but everyone doubted my JET chip and it did exist and did work, what about this, and if its legit and would work wonder if it would work on 96-99s as well....

The stock MAF isn't a restriction.

It might become one if you had cams, but who has cams?

i know its not a restriction
but doesnt it help control the timing by detecting air temp?
wont this be like those dummy intake sensor mods only difference is this one will WORK?

I don't think it'll work, at least not in the stock location. The MAF on a 96-99 engine bolts right to the throttle body, but on a 00+ engine, it sits inline in the intake tube. Pretty much right at the air filter box.

I think JET needs to put up some dyno charts before they're going to get any sales (at least from me).

I will not believe it increases airflow up to 45%. "up to" being the catch word here. If it actually increased airflow 10% I'll be shocked. It would be more realistic in terms of horsepower gains I would guess to be 3 to 6hp if your lucky. Dyno it.

hey id buy and dyno it if someone thinks itll work on a 97 Eldo lol

This is not a new item. Granatelli makes them too. The idea isn't to flow more air with them it's to be able to adjust and compensate for the addition of a CAI.

Here's the Delco part, fits 99 to 07 Gm vehicles including Cadillac according to the Delco vehicle list. Looks like the Jet pic.

minus the "oh so restrictive" MAF screen.

They charge extra for that. ($150 more to be precise)

You're right; the engine's only going to use as much air as it can. You can put a 5' diameter MAF on it and it's still only going to suck 'x' CFM. Maybe the MAF has the capability to flow 145% of the stock MAF. That really doesn't say anything to me.

I doubt it does anything, especially on a stock vehicle. With a different intake setup, larger camshafts, headers, high-flow exhaust, etc, maybe the stock MAF will begin to be a choke point.

No, the MAF sensor doesn't detect air temperature. That's what the IAT sensor does (Intake Air Temperature). On your '97 Eldorado, that's the small sensor plugged into the back of the stock airbox, if you still have it (the stock airbox that is).

The MAF sensor measures air mass, or density, as its name would infer (Mass Air Flow). It is just one input that the PCM uses to adjust fuel and spark mapping (the IAT sensor being another, O2 sensors being another, etc). I suppose the JET MAF sensor could be like those eBay IAT resistors, but I don't really think "fooling" the computer with artificial data is going to have much benefit. Whether this works better than the eBay resistors, who knows.

I would guess that the Jet MAF is designed to work without an airflow screen

Please don't double post. Pick the most appropriate forum (in this case, the Northstar forum) and if you need to, link to it from elsewhere...

my bad
not sure if this would be more northstar specific

An interesting NOTE on this is that in 2000 the IAT sensor is in fact part of the MAF. It's built into the center of the MAF sensor so essentially yes they are the same on 2000 + models. The screen in the stock MAF is not a restriction it's an air straightener to ensure perfect airflow to the plenum.
