Never updated this from the last era.....

 

Reinstalled a 2.5 low compression motor.... 320-340 whp with close to 380-400 torque.

 

12.5 @ 112 mph

 

Then lost the transmission (3rd gear)

 

Fixed the tranny, #1 piston went out the next day.

 

Built a whole new motor with 100mm Mahle pistons, did a 13.1 @ 105 at only 14 psi untuned.!!!!!!!!!!!

 

Then ate 1st gear last run of the year at PIR.

 

Awaiting another tranny rebuild....

 

Here are some pictures.

I have only blown one tranny due to racing. The first went out when I simply mishifted into 2nd at 6500 rpm..... The second time I suspect a tooth that didnt get cleaned out the 1st time finally made its way into the gearing as I was shifting OUT of 4th, when third gear got eaten up.

 

This last time 1st gear was sheared due to a 550 ftlb preassure plate that has an on/off feel. With hundreds of drag runs, I don't feel its that weak at all. It almost all comes down to driving style.
