[QUOTE="9T3SVT, post: 3630127, member: 26601"] I bought a Kenne Bell, threw it on and never tuned my car, 2 months later I blew a head gasket (no tune) It was a good time to replace the heads with AFR's and get a Vortech ;-) I bought my Vortech from [url]www.superchargers4less.com[/url] it was the best price I could find for the 1993 Cobra specific kit. I wanted that kit since our cars came with underdrive pulleys from the factory. Right after I finished my install I drove straight to my tuner to get my A/F readings and make sure it wasn't lean (lesson learned) The car came in running pig rich with the supplied FMU disc from Vortech. We swapped the disc, adjusted the timing, and cleaned the MAF wires. I gained 115HP between my first dyno pull and my last (again lesson learned) The only issue I had was spark blow out at full boost. My plugs were gapped to .035 so I closed the gap to .032 got Taylor wires and an MSD coil, problem solved. I run the Autolite 3923 plugs. They are inexpensive copper core plugs but the do the job. I see no need to spend 8-9 bucks per plug for iridium plus they're harder to read than a copper plug. Don't cut corners with a blower, it will cost a lot more later on, TRUST ME. Plan on a tune right away, I cannot stress that enough. Most of the blower horror stories you hear are from guys who never got a tune. They are also the guys who have a lot more horsepower that they don't know about. Good luck with the install, you're gonna love it :burnout: [/QUOTE]
