Message: [QUOTE="WoodsRider, post: 161370, member: 16545"] KXKen - You're right. I didn't build and set-up the engine to run on nitrous. I added the system later on to drop my ET into the low 12's. I dialed the system in per the NOS instructions. However I should have had the distributor "professionally" re-curved. The funny thing is the motor still ran fairly good. I'm not sure when the pistons melted or how long they were ran that way. At the time, that car was also my daily driver. You and I actually agree though. Nitrous set-up is very critical. Many people (including me back then) think it's just a matter of bolting up a kit. In reality it's more like trying to dial-in the carburetor jetting on your dirt bike. KLX - Do you drag race your Saab? If you read the owners manual for a turbocharged vehicle, they tell you to let the engine idle for a short period BEFORE shutting the engine down. We shut the VeeWee down immediately after (and sometimes before the end of) each run then had to tow or push it back to the start. It carried just enough fuel for the burnout, staging and the run. Anymore fuel was excess weight. Rockrider - You won't have these problem with a Roots or Paxton type supercharger. Check with marine vessel or semi-tractor repair facilities that work on Detroit Diesels. Sometimes you can get a good deal on those little 3-71 or 4-71 "Jimmy" blowers. [/QUOTE]
