okay i have a mild bolton GT with a vortech and a cxracing intercooler.. i wanna know will the 3.1 pulley push me into the 400s ? and will it be a big difference over the pulley i have now which is the stockj 3.60.
12 psi will up the risk of popping the engine, even with a perfect tune. The rods cannot always take that much power. Its a hit or miss kind of thing with the "miss" costing $$$$$. Hopefully they didn't build your rods on a friday before a vacation!!
