Friend of mine has a Foxbody with a 5.8 gt500 motor and a 4.0 whipple. Tuned by Lund Racing. Had shop do the conversion for and they did pulls on dyno with brand new crate motor. Best reading they could get due to tires breaking loose was 650rwhp on a "Safe" break in tune. Drove it for a bit and noticed smoking every once in awhile. Dropped it back off and car was down on power. Local engine builder took motor apart and had a blown headgasket. While it was out the rods and pistons were swapped for forged parts and cams degreed. Meth was also added for safety measure. Put motor back in and engine builder wanted 1000 miles driven before car was put on dyno. Drove the car 1000 miles then put on dyno and car is making 630rwhp. 22lbs of boost. Knock sensor is going nuts and intake temps are around 160°. Using a stock 2013 gt500 heat exchanger.
Shop wants to try and fix the knock sensor or tame it down, use a larger pulley to get boost down to 17-18 lbs, and switch heat exchanger to a larger one.
Shouldn't this motor make way more power than it is? Car is on pump gas with a few gallons of race gas added for extra measure. Would you back the boost down or leave it and use race gas or 93 with Torco?boo
