280zex Posted December 31, 2012 Share Posted December 31, 2012 (edited) I shot some video of a 4th gear pull while at a private race track. Unfortunately I wasnt allowed to hit 5th gear, as I didnt have an official car inspection, and this was my first time on this track. This shows how much boost creap my blow thru holley/t3to4e with internal waste gate set at 7psi will build. The fun thing is that if I stay out of the secondaries on the carb, I dont get the boost creap. Basicaly I can control the amount of extra boost over 7psi with the gas pedal. At wot in 5th gear the system will build to 20psi, and I get to 145mph @ 6400rpm realy damn quick!!

78zstyle Posted January 3, 2013 Share Posted January 3, 2013 Make sure all your vacuum lines to the wastegate are not plugged, or cracked, etc. I had the same problem and it turned out someone had stuck a piece of metal in the wastegate signal line..

280zex Posted January 3, 2013 Author Share Posted January 3, 2013 Nothing stuck, just the way my system works Quote Link to comment Share on other sites More sharing options...
