Again, not enough HP to be an issue. You're running very rich as a result of that Boxter MAF. You should try the correct MAF. Your car should run better and have more power.

 

Use the stock intake. It's a little concerniing to see that post about the guy with the new WAFFLE insert. I thought that was supposed to fix things.

I can pop a MAF in under 5 mins using the VFlow - I have 6 dead MAFs in the garage . I would suggest putting the stock intake back in with a K&N filter until you get a fix. That's what I have done and haven't blown a MAF.

 

I blew 3 MAF's in 2 months with the V-Flow. Blew my first this weekend
with the stock air box/K&N. It lasted 5K miles. Better...but still blowing them.

 

My understanding is that the Boxster MAF is definitely more durable and can take the abuse. How about a program to retrofit a Boxster unit with a compatible flash. At least with the boxster MAF the factory flash will work.

My understanding is that the Hitachi MAF retrofit still requires a new flash but renders the factory flash unusable.

I'm a bit reluctant to completely abandon the factory flash due to warranty issues.

 

Is the blown MAF problem more common in the GT640 and up levels of HP? I was told that below 600HP, it shouldn't be a problem....I blew a my MAF about a month ago. My dealer replaced it still under warranty and no issues so far. I have to admit, i've been babying the car a bit..afraid to blow it again. what a pain and i'm only a stage 4 car.

 

you guys are just trip'n. mafs go out all the time. it's just a coincidence. remember?

 

Can someone post of a pic of the waffle? Curious to see what it looks like and how it works. Is the EVO box worth it for a few extra HP??

 

You can definitely feel the EVO box. Don't have a picture of the waffle, but it is a piece that is pulled out of the factory box. Take a look inside and you can see it (there is also a fine metal screen in there as well).

 

I have 22k on my chipped x-50 with exhaust and wastgates have not blown 1 maf yet. my engine does not have the required (excess) cfm to take out the sensor. IMHO the ring I was shown, EVO's fix does not decrease the air feet per minute (fpm) through the intake tubing so I am not suprised that guys are still tearing the element on the maf's. The intake tubing needs to be increased to drop the fpm across the maf, then the program needs to be re-done. again just IMHO.

 

This is not happening on any MAFs to my knowledge. It is an electrical "surge" that is blowing the MAF...no physical damage.

 

thats interesting, the problem is air flow (only happens on high hp kits)

 

wow! evos are actually causing tearing?! takes quite abit of turbulence to physically tear the element. first I have heard of this.

 

you may be right air folw has no effect.

 

You assume the problem is volume (or speed) of air....one theory is that it is the turbulence of the air causing surges in voltage (spikes)...this is what fries the MAF (since our MAF is a foil...it estimates the flow of air by calculating the delta temperature from one side to the other and sends a voltage signal to the ECU). Turbulent airflow disrupts the delta T reading...perhaps?

 

Waffle. Useless.
