...talk about taking a LOOOONGGGG time to get back! Sorry. This is actually my first nitrous motor and I'm in learning mode myself. I love the naturally aspirated stuff, but the recent popularity of the SSO, OPS, etc cars has driven me to get invloved.
We've been having a heck of a time with transmission reliabilty too. I love the 5 speed clutchless trannys (we use the G-Force in the car in the top picture), but autos are kind of helpfull in these heavy, tall, slow steering "street cars".
The engine in the bottom picture good for 860hp on motor, but the nitrous system is now good for a "700 hp" shot. I orginally planned and asked for 600, but Branden Switzer wound up giving us the extra 100hp system.
This particular system (not plumbed at the time the pic was taken), is a two stage fogger. That is, there are two separate circuits, and they come in at different times. Each supplies nitrous and a necessary matching amount of gas (to ensure the proper fuel to air ratio). The nitrous is an oxygen source. If you think about it, air is only...what 24-25% oxygen? Nitrous is 33% oxygen (N2O). Then consider that nitrous comes in under pressure and is cold, both of these conditions drastically increase the cylinder oxygen content. So, in effect nitrous is a form of super charging....but it is very important to keep everything in correct proportion.
Which is why I was soooo late getting back. Not only did we destroy another tranny this past weekend, but hurt the engine a bit. Not too bad (fortunately), but it needed/needs attention. Not enough fuel, too much timing and...leak down rates in the 30% range.
Sorry, we don't run in the mid-west, but it would be cool to take a visit. We run mostly in the state of Maryland. We are blessed with an abundance of local tracks and good fan attendance. Sometimes we go to Reading (MRP), but usually stay "home". One of the Pro 5.0 teams has asked us to join up as a team Supper Street Outlaw (SSO) car. If we take him up on it, maybe we'll do some traveling...who knows?...to be honest with you, I just like tinkering with engine combinations more than anything else.
Hope you all had a good weekend.
