Hi,
I am new to your forum but it was strongly
suggested by a member of the Xfire forum that I join.
I recently "upgraded" my 84 Vette Xfire with a Comp
Cam hyd roller 211/218 degree with .488/495 lift at 112 degree lobe
separation. I also upgraded the heads to the new
Trick Flow 23 degree aluminum heads. Also have
upgraded ECM and TBI units to Turbo City
systems ie 7747 ECM. I also have Extrude Honed
manifold. On a 95 degree day, car ran a 14.3 at 99.7mph and pulled 253
hp@4600rpm/307 lbft@4200rpm at the rear wheels on chassis dyno. This was with
stock configuration chip. I am interested in knowing if anyone has a bin file
for a combination similar to this. I don't doubt that knock Sensor was
causing retard of timing since power went south after 4600rpm. I have a
Needhams EMP-10 burner and would be interested in mainly suggested fuel
and timing calibrations. I believe it is running slightly rich especially at
cold idle strartup and would also like to address dis/engagement of 4+3 OD unit
at higher speeds.
Thanks for your help,
Dominic
