Anybody have any experience with the Granatelli setup that comes with a new MAF and doesnt need a tuner? Granatelli claims 48 hp gains with his bundled cai and exhaust kit for 650 bucks.
I thik C&L is the best mainly because of the heat shield. I bought a Tunable Induction one which looks sweet and makes about the same power on the dyno compared to the C&L, but the heat shield doesn't seal up to the hood and I get a lot of hot air. I made a custom top part to shield it from heat (which makes a huge differance when driving) but I am considering buying a C&L to replace it since I want to open the hood and have it look good for shows...Muscle Mustangs & FF did and article for track times and the colder air intakes did much better on the track (they tested air intake temp too and the coldest air intake had the best track time)
I'm not discounting your claim at all, I DO beleive you gained 18rwhp over baseline. But I want to say that these claims are INCLUDING a tune (correct in your case as well I assume?), I've seen guys gain 20rwhp with a stock intake and just a tune, although a tune alone is usually more like 10-15rwhp.I put on a JLT kit and had it dialed in on a dyno, picked up 18 horsepower.
Cold air/hot air/...... It really does not matter, and is more personal preference.
I agree with your whole post except for the part I quoted. Inlet air temperature is a huge factor; with everything else being the same...a few degrees cooler air can make a significant difference at the rear wheels.
