On a 346" motor with lots of n2o...300hp or so. I may be buying new headers. Would going bigger help? What brand? What do you guys think of Thunders race header?

I have FLP's now that the egr tubes are broken off and they ae getting old and beat up.

Would have made a 9 second pass friday night if it werent for the EGR breaking off. Ran a 10.12@133.

Thanks for any input,
Shawn

 

anyone?

 

FWIW I'm running the good ole Mac headers. Made 700 rhwp and went 9.40's. Save your money, put it towards something more important!

 

Hey Mike, just curious but what rods and pistons are you running? I'm impressed with how much abuse your motor has taken.

 

Eagle rods and JE pistons.

 

Yes the headers will help. I changed a set of 1 3/4 headers on the dyno to Kooks 1 7/8 and the car made 10rwhp more on the motor and made 37rwhp more on the exact same shot of nitrous. This was just a 150 shot as well. So i'm sure your gains would be even more with a big 300 shot. If you change get nothing but kooks.

 

how much did you loose down low with the bigger headers?

 

Absolutely nothing!!!!!
