LS1 maf

Now THAT will be some cool data. It'll highlight the difference between theory and practice. Do you have a powerlogger with boost input?

I agree! I'm in, and yes I can get some logs. Unfortunately this will be the car's maiden voyage to the track (with me) and Im way out of practice and will probably get garbage data... the previous owner ran a 10.7 @126 with a very sloppy tune and zero turbo buick knowledge (ran the alky tank dry @27psi on the next run, bye bye head gaskets and rod bearings). I have tons of hours, lots of parts, and 10k miles Iinto it since I bought/built it and its finally track ready. I'll probably just run the back end and work on tuning wot fuel. Unless it hooks hard, then I'll stand on it and run the number




Man, you're piling up some nice parts! Is the turbo inlet 4"?

Don't mean to hijack but I am putting similar on mine. (Trans 1 w/ LS-2 maf) I intend to go with the ported turbo as you have, I would think a 4' coupler from pipe to turbo would work, let us know the results !!

Even better since your car moves some serious air. It will highlight any pressure drop MUCH more than it would on a normal hot street car.

The biggest variable to quantifying spoolup speed is the loose nut behind the steering wheel and his throttle application rate

May be some confusion, Im running a speed density chip, just never removed the maf (3.5" ls1). The brfore and after would be with and without the maf to see if theres a difference. It'll be neat info to have either way

No doubt, my butt-dyno confirmed a pretty substantial decrease in spoolup time just going from a 3" lt1 maf and pipe to a 3.5 last year. Honestly I'm a coward when it comes to heavy "throttle application". with the amount of time and tlc I have into this car i'm terrified to blow it up hahaha. I'll grow a pair when peer pressure kicks in at the track

Get up to 100 before you punch it. That'll lower the violence when the engine comes on the pipe

Well I just order a translator. Ill be changing from a stock MAF to a LS1. Can't wait to see the difference. Last time at the track it ran 119.xx with 22#.

Problem is: when I mash it at speed, it almost always grabs an unplanned downshift and violence ensues hahaha. P.s. I love "on the pipe"... two-stroke talk, but it's extremely accurate since thats exactly how my car pulls (apologies to O.P. for jacking this thread)

 

[rev. 3:11]

I'm using a 3" hard pipe w/ an 85mm MAF
I went to Home Depot & found this:
its a 3" to 3.5" coupler
Found it in the air duct section, (not plumbing!)

part # IRB43 ($2.50ish)

its light & thin, but sturdy enough

Here it is installed;
I just shot it black, trimmed the notch to align the MAF
& glued it to the MAF
works like a charm & cheap to boot!

Better throttle response and quicker spool up. Glad I did it.

 

[Wahoo]

I just tried to install my lt1 maf today, its a 3" and it doesn't fit the stock intake pipe. Don't know where I should buy some piping to make my own cold air intake. I went to Home Depot couldn't find a coupler that works toget my LT1 maf onto my stock intake.
