Well Guys I need your help,

I'm looking to get a bit more out of the XR8 (EB 91) and am toying with the idea of going to a bigger MAF. I currently run a standard MAF but have upgraded the Throttle body to a Edelbrock 65mm.

It also runs Pacemaker Headers and K & N Pod induction.

Will going to a 70mm MAF give me any more or am I wasting my money.

I think it is a waste of time until you get some heads, intake an larger fuel injectors. Fordmuscle.com tested a C&L 73mm MAF on a stock and mildly modified 5.0L and found no improvements.

I agree

Due to your throttle body being 65mm[now] a 70+ maf would now help especially with exhaust mods.
With std motor a 70mm maf won't help due to throttle body being 60mm std as in test done in mag..
BUT heads and inlet are a must for real performance..As said above..
Make sure the maf is calibrated to the size of your injectors..

Any chance of telling us what other work should be done to make it worthwhile going to a larger MAF? Or is the MAF not replaced until a high level of mods are done?

As said above, atleast port your e7 heads and buy Edelbrock,Ford Cobra /Explorer type gt40 inlet,Trick Flow,inlet. Say $500.00 second hand or $1100 new.. Heads alloy looking at $2500.00..Or get some gtp's.. But porting will be cheaper if you check around..Then in my opinion std cam and 1:7 roller rockers..Any more then??.. 24 Lp injectors and recalibrated maf..
Though you can get away with rising fuel pressure alittle on the 19's with an adjustable fuel regulator fitted..A larger maf will help "alittle" in your case, the early V8's had small mafs..

Your engine is only going to use what the cam/rocker will let into the chambers.
