Why is my FI setup getting to Hot? This is the second time this has happend. I'm not abusive to the car, I just got it back again....

Here are the details;

Forged 347
Ceramic coated Wiesco Pistons -12 cc
Lunati Rods
Stock crank
AFR 205 Heads at 58cc
232/236 115 lsa cam
D1 Procharger with 4" pulley 12lbs at 6800
Stage II Procharger bracket
A&A Stage I intercooler and piping
Vortech Race BOV
A&A Fuel System
Kennebell BAP

Car was tuned conservatively with 17* timing up top, and pig rich on 93 octane.

The motor had about 750 miles

All of the rings have no tension

Several of the pistons have had the coating gone and the edges of the pistons are cracked.

There are no signs of detonation

Coolant was never more than 185*(+-)

Oil temp got to 225* never more

No over-rev

I shift at 6200rpm

I was told the tune was spot on......

Any suggestions from you guys

 

anyone?
