**Twin Turbo 67 Dart Project**

Sure you mentioned it already.....but please tell me that you are not going to be another one of the turbo street cars with out air filters? I always laugh when I see "street" cars with no air filters, or for that matter running race gas on the street. Hardly call a car that you can only go 30-40 miles from home without turning around and getting home before you run out of fuel a street car. I do not know where anybody else lives, but the 3 places I have lived in do not pump race gas at the local gas station....

I am with you Doug, however the fellow who got me started in all this turbo stuff ran a TT Barracuda that ran high 9s and it was his daily driver for 3 years. Granted I think his daily commute was 8 or 9 miles one way but he never had a filter on it. He did put some screen (as in a house window screen) hose clamped on the inlet. He never did have one problem with it. I too ran my dart with no filters with no problems although my car only did 7-11 runs as a street car. If you can fit one run it. I am not sure if I will be able to fit one on my car so I may be one of "those" guys. One thing to remember is that the turbo is moving so much air when it is making boost that its easy to choke it with a filter. Just some food for thought. Another thought while I am posting is the exhaust. Now I have been told and have always run a exhaust pipe diameter that is 1.5 times the outlet size of the turbo. Some say its necessary and it can limit boost and make the turbo work harder if you run too restrictive of an exhaust. I have never run small exhaust so I cant endorse that comment, but I thought I would mention it in case you have trouble with late spool times and possibly not making your target boost number. That is all, now back to Maddart making me look bad by how fast he is doing this!!!

PS These turbo cars are very efficient and get ridiculously good fuel mileage. I know that 20mpg is easily attained if you can keep your foot out of it. My car has a 20 gallon fuel cell so some quickmath gives me a 400 mile range. I think that qualifies as a street car. Another thing I used to do is limit my boost to 5 pounds on the street and run 91 octane in it and it ran perfect and still would run mid tens like that!! I think both you and Louis will be laughing at the end of your builds when you see how mellow and real world these cars can be. Just look at the Grand National guys!
