Hi, another 8.1 guy hear that likes picken on mustangs . I have a 2500HD ecsb 8.1l allison. mods are K/N filter, ported TB, 1.8 rockers, comp xr270 cam, tog headers, NX 200hp, and duel 3" exhaust with an X-pipe. Made 322whp, 433wtq, and 504whp, 618wtq with N2O. Ran a 15.00 on motor and a 12.95 @101mph 1.7 60' on go gas. Broke 3 sets of tierods before I got the frontend to stop wheelhopping. But the engine down right now busted the ringlands on a piston which gave me a reason to build a bigger and badder motor.http://www.dieselplace.com/forum/smileys/Evil Smile.gif

Welcome!!You got that beast running good.http://www.dieselplace.com/forum/smileys/Big Smile.gifNow maybe you can run a duel stage N2O setup on it.http://www.dieselplace.com/forum/smileys/Evil Smile.gif

Thats the plan two stage one 100hp second 150hp the new engine will be a stroker and should make 625hp all motor. This could be fun!!!

Welcome to the site. Your truck sounds like a beast! Good luck with the new engine. Hopefully it will stay together for while...http://www.dieselplace.com/forum/smileys/Big Smile.gif
