I guess the biggest thing I want to ask ....long story short I was tryin to get brodix tech line today and was going through there web site, and pulled my heads up, and it said they were good with a 14 to 1 minimum compression ratio. ?????????? I have tons of other questions but we'll start there ..LOL BTW based on my experiance today , good luck getting a-hold of anyone at brodix. They did send an e-mail back saying ."sorry we no longer carry that product" I E-mailed back really there still in the jegs catalogue.
