Are we sure that the GT-R MAF's would work?

No I think it was noted that they are the same MAFs that we have in our car. I am willing to bet they switch over to speed density tuning which allows them to just tune via the boost. Then out of boost they run the maf for its ability to be more refined.

That is very correct. The maf's can take the gtr to high 600 and then it switch to map which is unlimited. Ecutek said when they released there race romantic we would be able to do the same but as right now there on pace for GTM standard of never. But just wishful thinking that they could make it happen

Bummer! I found new GT-R Maf's for $80. :rolleyes:

$$$ - Cuz they can.

UpRev MAF GT - Accessories

So everyone that has gone built has had to buy these?

No you can go with a bigger MAF housing, which is what I am trying to get my hands on currently. When I do I will share my results on here and see how much more you can flow through a 3" instead of a 2.75". This will allow for a the stock maf to register a larger airflow without having to change the MAF.

A little excerpt I found in one of my tuning books. The idea that you could essentially run via a map is a little intriguing.

For the guys who want 3in charge pipes the material $339.00 with tall maf adapters and without blow off adapters. That's just the material u can get it and have someone fab it up its real easy if u can weld aluminum.thats all new pipe from the intercooler to the TB's...I'm doing this soon as I get home I don't want to run Into the problem some of u guys r having...it should lower ur volt to around 4.3 from 4.9...

Do you have a link to the pipe sections?

It's a local place that I work with but u can check out treadstoneperformance.Com but there expensive but check it out..

This is basically what the oldschool HKS VPC did. MAP piggyback that outputs a simulated MAF signal to emulate the original sensor.

This will not work on the 370z. Unless you locked the VVEL shafts in a static position or something, you cannot run a VHR off speed density during engine vacuum.

I will have the 3" charge pipes available for the BP customers. These will be about $280, powder coated, and a direct drop in for the 2.75" pipes. 4 new couplers will be included as well as 4 new T-bolt clamps.

Dam I wish I could get pipe that cheap

according to their website it is just Hitachi part # W0133-1723137. I doubt the modify them at all, and they can be found for $200 on other sites.
