Boosted My SC
so youre trying to say that people that "upgrade" their MAF sensor are paying the extra money just for the housing. stock sensor/housing is around 40 bucks. ls400 sensor/housing is 100-150. people pay extra 100 bucks for the aluminum housing?
The larger housing with the same MAF sensor reads roughly 25% less air. You add 25% larger injectors, and you end up with something that closely resembles a stock setup. From there you do some fine tuning.
Let's not clutter up this guy's thread, if you don't agree with me, feel free to AIM me or PM me and I'll provide you with tons of data to support my claim.
The "lexus AFM" upgrade has been one of the cornerstones of my business for the last 6 years and I've gone through at least 50 upgrades in my experience. Supra guys jump on larger lexus 400 AFM housings like it is going out of style.
What you are posting is incorrect, and i want to make sure that incorrect information is not repeated over and over.
If snomanlex wants to put in larger 440cc injectors, he can compensate for those injectors by putting in the LS400/SC400 MAF housing, keeping the same black electronic box.

Props on installing the set up so quickly!! Looks like a solid kit. I would be worried about the dp being so low. Looks like it will definitely get whacked and hard. you may want to consider changing that.

The kit is definitely solid. Ive actually been using xspower products for a few years. I've always had awesome results so getting this kit was a no-brainer for the price. And the pipe you see was actually the intercooler pipe. The dp fit awesome. That just had to come up a little and it was all set. I clear pretty much everything.
What you are posting is the part number of the MAF electronics (the black piece). The LS400/SC300 housing is what is bigger. So changing to LS400 eletronics does nothing for you, you need to change the actual housing to have the ability to compensate for injectors that are 25% bigger.
Snoman, nice piping, who did it?

ince it is the Intercooler pipe, should be easy to raise....Let us know myour numbers once you get it tuned.

So... let me get this straight. You are saying all you need to do is change the housing, not the part that actually registers the amount of CFM. Correct? The actual electronics part does nothing.... it's all about the area inside the housing.
If you wanted to compensate for 25% larger injectors, you would put on a 25% larger housing. That just happens to be the 400 housing. You keep your same electronics. The electronics will "sense" 25% less air. That is why you need 25% larger injectors to compensate.
BTW, I had a typo in my statement, if you can fix it in your quote, that would be great. I meant to say "LS400/SC400 housing", I was just up too late lol.
I thought this larger housing thing was understood across the board. I'm surprised at the people that are instantly calling me out about it. This has been proven for years upon years. I've been taking heat all night for some reason.
I apologize to snomanlex for all of this drama taking place in his thread. Like I said, if you think I am wrong, PM or AIM me, and I will explain further.

I plan on installing the same kit on mine after this next deployment, One question did you use the IS300 union bolt for the oil tap? Or how did you do it?
Thanks for any info.

Haha. Obviously you haven't been on here very long. We have everything from glowing compressor housings to people claiming they are gonna build the worlds fastest SC after they blew a simple NA-T setup cuz they were clueless. "Modifying" is used as very broad term on this board
. Anyway I understand what you're saying, a slower and less dense air charge in the entire housing will cause a lower reading, therefore registering less fuel required. I'm not too hip on MKIII stuff but that's good to know.
