Okay, so your comparing a 3.6l engine to what a 2.5 engine will give?!?!?! Even with that pretty dyno, I don't belive for a second that it gave that much gain. Any real tunner would laugh in your face.
Also, Sports car Revolution never had any air hog comoercials, much less 10 of them so now you are just making shit up or tring to put words in my mouth.
Read up on a mustang forum and talk real HP gains from bolt ons. You will never gain any real power untill you make the engine pump more air. You can make your car go faster with basic bolt ons with the spec v because it is a light car, so any gain will be felt, but short of doing head and cam work, you can't really change much. The mustang guys know that when you read 10+HP from a CAI kit, it is a joke. It's ricer HP math. If you belive that a CAI can give 10-12HP, well, maybe I need to start making ebay CAIs cause everyone thinks they are the answer to HP from the HP gods. I can find race shops that claim up to 10+HP too, but it doesn't make it so. RPM outlet is the biggest joke to fake HP gains. Read them for a good laugh.
This is the absolute last post I am going to give on CAIs. It is silly to think that a different intake kit is going to make all the difference in the world. I know people who have bought them so something looked cool under the hood too.
This will probably get locked or deleted, but here it goes. I saw a spec v in town with a exhuast on it. I wanted to know how much faster it would be over my car. I was able to line up to him and when the light went green, we went at it. He was a tad faster on top end, but lost everything he gained on the bottom of 2nd. I cut if off around 50MPH and our cars were even. So much for that costly exhaust setup.
I've never paid for a dyno. When I want to know if my changes have made real improvments, I go to the track. Test and tune is well under 10 bucks. How much is that dyno? Who cares what your car can do standing still. Besides, cars act differenty when they are moving and a different intake can really change things.
I know that street racing stories are not allowed and I support that 100%. I calmed way the hell down after I got married and got old n such, but you can never really know what your car can do untill you take on other cars in the same class and other drivers. There are such things as private roads and roads with no cars and small town airports with long runways. It is easy to take it off the street if you live too far from a track and you want to play. Hell, write to the local governor and tell them you are interested in getting racing off the street. See if they can find you a place to play. Dyno's can give you a good ideal of where you are, but they are expensive and people always argue over how the dyno was set up. If you go to a good drag strip with a full 1/4, no one can really call BS on your printed times. If you want to be honest with yourself and your mods, try and make sure the temps and humitity are in the same range during your runs. Also, first place drag runs are fun too. If you beat a faster car on camera, you got that too.
