What is the Alt. / DA for your runs?Any work to the heads? Thx for the help. Nice runs BTW. 36XX is alot to move fo-sure.
our track is at sea level but the avg. DA is around 800 ft. it seems on an avg cool day. heads have had minor cleanup, stock valves still, 2.19's. if you want to know any more details just let me know.

heres a vid, last pass is on the bottle, rest n/a.

What wheel HP does that thing make on NOS? Was that long dyno pull with or without bottle?
n/a passes only just to get the carb in tune with the car. its on a mustang dyno. final it made about 480hp and 600 lbft to the tire. my baseline pull to my final pull we found 20rwhp though after tuning. it can be taken with a grain of salt though cars in drag trim on chassis dynos always do funky things to the numbers IMO. on the engine dyno with an 850cfm carb it made 625hp and 570lbft on a DTS on the 150 shot it made 830hp and on the 200 shot 880hp.
