6/9/17 Update
I removed the power valve on the secondary side of the carb and plugged it off. Jetted up a few sizes to compensate for the missing power valve. Also installed brass jet extensions. Hopefully this will be the silver bullet that kills the bog on launch. I have a pretty good feeling this is the fix. We'll know later. Going to do a little testing tonight. If all goes well. We sould be mid 10s easily. And we'll be ready to move on to the nitrous and chasing high 8-low 9s.

Im sorry guys. Never got to the track that night. My unit is down for turn around at the refinery. So I'm basically working 7 days a week all month. I'll be getting after it again soon though.

Haven't updated this in a very long time but.....The Nightmare now runs the way it was built to run. I fixed the bog issue last fall. It ran amazing once everything was right. 10.03@136 is the best motor run. Made that just this past week. The car will cut low 1.4 sixties on Motor. On the nitrous. The best run has been 9.34@145. With low 1.3 sixties! This will probably be the last post because I've decided to sell the car. Owning a race car is constant work. And im getting old. So ill use the money from the race car as a down payment on a GT500. When they come out next year. Here is the last of the phots that'll be posted of the nightmare. It was a fun project. Not many people can say they helped build an 8 second capable car. But time to move on.

It was a long project. And for the most part. It was filled with a lot of skinned knuckles. Fighting with crap shops. (Anyone from new jersey. Skip radical racing & Absolute auto!) Shop owners are not at all what I'd call quality mechanics. And at the end of the day. Just racing a Nitrous car. Is a ton of work. You have to carry a full tool box. And check spark plugs after every run. You have to carry a laptop to change timing on the fly. And just dragging the car on and off of a trailer is a hassle. The up side is a low 9 second ride is a heck of a rush. So the next rush will be owning a street car that will do over 200MPH. I'm leaning GT500 but a Hellcat would also do the trick.
