MAF guestion for 306 with kenne bell

I have heard great things about the SCT Big Air MAF. and also the Lightning MAF is a proven quality piece.

I don't have any experience with blower combos and I certainly don't wanna make it seem like I know more than a Pro Tuner here.

Lots of peeps with forced incduction combos have used 42's and that maf for their combos in the past.

I find it hard to believe your gonna peg that maf. That maf & cal will support a good bit of air flow.

I think you are wise to ask this Q. I'm looking forward to some insite on this myself!

Hopefully someone with more experience will get involved here.

Like John, I also have heard good things about both of those mafs.

If the Anderson MAF is essentially a Pro-M calibrated for 42's, you are not going to peg it unless it is badly calibrated. We have seen Pro-Ms calibrated for 42's peg at 330 RWHP when they should be good to 500 or so. I ran a Pro-M calibrated for 42s in my own KB car for years and never had a problem.

The other thing is KBs are NOT dyno queens - you most likely will not see 450 RWHP, in fact if you did with a 1500 and 9#, it'd be a miracle. More like 350-375 is realistic. But that's not to say it will not run great - it will. The 1500's on a 5.0 with good heads just plain run out of steam at higher RPMs, you'll likely experience a boost drop at 4000 and up when the motor's airflow demands exceed the blower's ability to provide the airflow. My 5.0 with a 1500 went 11.7/115 in my 3700# car and it only made 360. When I added a 2200 and a Flowzilla, it went 11.1/123 and only made 405. KB'sd are NOT about peak power - it's the high broad torque peak and the power under the cuver that move you along.

The combo most people with 1500s have best luck with is a 90mm LMAF and 42's. A BA 2400 would be OK too, although way overkill. You are supposed to size your MAF so you are using 80% of it's range - so you have good resolution and good driveability and a BA 2400 will be way over what you require.

I honestly do not remember what boost I was running, but I think 8-10#
