I am getting ready to buy a 89 for real cheap. I plan on running stealth ram and zz4 cam on stock heads. Does anyone have an idea if this will max out the maf?

Thanks

As an educated guess I'd say that the MAF will probably be near the upper limit. Best bet is to try it and see how it is. Then go from there. Would also depend upon the heads used.

I was hoping someone might know bcuz I would like to just skip the whole thing of trying if it isn't worth it and switch to SD. It will have 1.6rr, lt headers, orp, and some catback. I will be running different springs and new pistions bcuz the motor needs to be rebuilt.

 

Of several dozen folks that I know of that have gone from MAF to SD, I've heard of exactly one, that didn't think it wasn't a worthwhile swap.

 

according to Myron Cottrell of tpis,our mass air flo systems can handle up to 500 hp,i do not beleive that set up will acheive that type of power,do some chip tuning,possibly talk to the tech's at tpis,lpe,slp etc......

 

Handle yes, but can the MAF read that high, because if not then it is max'd. It all depends upon what one is looking for.

Don't use a maf system with the stealth ram. Sure it'll work. But why use a restrictive 2+ inch hole to breathe from. I have SD on one of my cars(it use to have maf). It has worked out very well. Besides, do you want to pay $160 when the maf goes bad? The 730 swap is not hard!!! I can run a 4" cold air intake tract with SD. That's a lot more airflow potential. That means more power across the entire curve.

There is one person I know that ran fast ET's with the MAF system. Too bad they didn't give SD a chance. It's not the point of going fast with maf. The point should be what's best for your engine. IMO, the thirdgen maf is not good for WOT performance.

 

lets not start a MAF/SD war here MAF will work fine for your application.. even if you max out the MAF its not the end of the world.. you can still use PE. besides MAF handles mods better so you get better overall drivability not to mention if you switch to SD you're going to be burning ALOT of proms.

you have a few guys on this board running 11's on the MAF system with superrams.

 

That is the last thing I want to do. I did say that maf would work. FYI, I have used the 870,165($32/$32B/$6E) and the 730 on my 406sbc. It has a stealth ram on it now. TPI was on it before. I was just spreading the truth....

 

Answer to the original question: Probably not.

I would get it running with the stock MAF setup and then switch to SD when you are comfortable with tuning...

HTH,

 

That's what I ment to say

 

It's not a war.
No one has said you can't go fast with a MAF system. And there are cars with drivetrains like the 89TTA running mid 9s with them. But, that's hardly a daily driver.

Drivibility is about what you find is acceptable. For some folks the oem settings are just fine, while to others, they're miserable.

Yes, using a higher resolution system takes more work. And you'll notice all the aftermarkets are going that way now.

Tuning any system to be CORRECT takes burning ALOT of chips. And if someone is new to EFI most of the chips they'll be doing is in learning how to tune. Aftrer doing enough of both systems it gets to be rather moot as to what one's working on, well at least to me.

 

There is a difference between handle, and being doing it with having real control of the system. Heck just run the injectors static, and add enough toluene, and you can make HP with very little tuning. Heck for timing, you can just set it all to 49d and run on the knock sensor if you want. But, then there comes the day you do a tear down, and may find some serious problems.

 

It's not just that. It seems like a plain misunderstanding on how efi works. Sure 22lb injector will "work" for high hp but why shoot yourself in the foot. I say do it right the first time, unless you like to redo/replace the work that has been done....
