Topgunz - air to air upgrade

TopgunZ · 07-27-2016, 07:26 AM

Well the good news is that if you stay with 91oct then you wont need a rfs. The only reason a rfs is needed is when you need to pump 30% more fuel due to E85's consumption.

Regarding the MAF's and tuning with Uprev... The stock MAF's should work fine with the 8 or 9psi pulley. However, if you upgrade your supercharger to the Si trim and start pushing a lot more air over that then they can be maxed out before redline. MAF's are strange. I had a long conversation with Sebs from Z1 motorsports about this (you know, the guy tuning most of these cars) and he said that they are a bit unpredictable. One car can max out voltage 1000rpm's earlier or later than the next on just about every kit he has seen on the market.

Again. I dont see this becoming an issue until you are maxing out the kit. And then heck, might as well get EcuTek if your trying to squeeze every last pony out of the car. We have seen it can pull out a good bit more over Uprev tuning. The MAP sensor is pretty cheap anyway.

anyone have any tips on getting the ypipe to fit better/easier? I've cut a decent sized hole in the radiator support so I know thats not an issue. I struggled for about 30-40 minutes trying to get it to fit

Are you spraying the inside of the silicon couplers w/ Windex? It's a really good lubricant for them. Makes them slide on much better.

I work at a dealership so I tried using an aerosol silicon lubricant. The rear throttle body connects up fine its the front one that is being a pain in the ***. Its almost as if the pipe needs to be dropped down further but to do that ill need to start cutting in to the metal.

Mine was def a PITA to get installed. But after ample cussing & lots of Windex & lots of wiggling of the Y pipe, I was able to get it to fit. You certainly shouldn't need to cut anything.
