I drove their teched-in and did 4 passes back to back. This was my 2nd pass. Cut-out full open, tires at 36 PSI, Tail gate up. Its better, but I think the weather was hurting me again. On my 5th pass I dropped the tire pressure to 28 PSI & opened the tail gate and ran an identical time. Can someone tell me what the DA was at NPR at 6:32 pm? I would like to know the corrected time but don't know how to calculate it. I made 9 passes all together and had a great time. Results are listed below

you still running those steel wheels? try finding some cheap 17" alloys to replace them with. the steels are very heavy.

 

I'm running the chrome wheels that came with the truck. Are those the ones you are talking about?

 

Yeah, another member replaced them with alloys and took off 2-3 tenths I think.

btw: whats the zip code and elevation of the track?

 

I may have to look into some tires. I'm thinking about doing the cam TR220 on 112 LSA, stall 2800, PS LT headers and ory all at once. any suggestions?

zip 70341 & EL. 12 ft

 

Yeah, more stall. 3000 at least, I'd personally go higher.

 

Good deal man.that was with the 87 octane tune also.If you ever want to step up let me know,the results would be much much better.
