Mods list

Fmic
3.5" gm maf
Maft version 2.01
Fic 650's
190 pump

In order to get the idle right i had to set the maft to stock injector size and am gonna use my safc 2 to do what i need with fuel.

Before i was running the maft i was running a hacked 1g maf and 390cc inectors. May sound crazy but i never hit fuel cut at 20psi and car pulled good and hard at wot to 7000.

I know i need to log and tune. The knock sensor is broke but its been broke since i had the car.

Everything is the same i just added the 650's and the maft.

Also this is on a 14b btw.

Ok here is what i notice. At 75% throttle i still build 20psi and it does not break up. So its only doing it at 100% throttle. Must be an airflow problem..

Think i found the issue. Plugs are fouled and it was running pig rich. Had to take 30% out of the safc just to get the car home tonight.

well good job for figuring it out ;-)

Just when i thought it was figured out i was wrong. Went to crank the car this morning to go to work and it was hydralocked. Went home on lunch to diagnose the problem.

Pulled the plugs and found number 4 to have alot of fuel sitting on top of the piston.

So i pulled the 650s out and put my 390s back in. Put new plugs in it and fired it up.

Number 4 connecting rod is broken :-(

Number 4 injector stuck wide open this morning and this is what hydralocked the motor and broke the rod.

Damn, tough break man. Is the rod actually broken? Any damage done to the block?
