Greetings everyone! I'm new to this board, so I hope I can find some good information and advice from everyone here.
My local Ford dealership just traded in a 1998 SVT Cobra coupe, canary yellow, black leather, every option in the book, it has 118,000 miles on the body, 60,000 miles on the engine. The engine was totally rebuilt by SVT when the previous owner heard a noise in the engine and he didn't want to risk it, so they totally rebuilt it for him. I was very impressed with the car during my test drive, and I'm thinking about buying it this coming Monday.
I talked to the previous owner, and he said it dynoed 346 horsepower at the wheels when he tested it recently. By my math, that's 416 at the crank! I asked what mods he had done, and he only mentioned a K&N filter he had added himself. He also said the owner before him mentioned putting in a Diablo performance chip on it. And according to him, those should be the only two modifications done to the car. Everything else, exhaust, gears, etc... being stock. I didn't notice anything else on the car that would be an obvious power adder.
So my question is this: I hate to call BS on this guy, but there's no way a K&n filter and a Diablo chip can add up to a 90 rear wheel horsepower gain, can it? I can see 30 or 35 gained, but not 90. Either he's BSing, or there's something else done to the car that he wasn't aware of before he dynoed it, or those Diablo chips give more power than they claim. I will admit though that when I test drove it, it did feel stronger than stock, so I wonder if there is something I'm blind to see on it.
Any thoughts?
