this came up in another discussion but is worth reading:
http://en.wikipedia.org/wiki/E85_in_standard_engines
sample quote:
E85 gives particularly good results in turbocharged cars due to its high octane. It allows the ECU to run more favorable ignition timing and leaner fuel mixtures than are possible on normal premium gasoline. Users who have experimented with converting OBDII (i.e., On-Board Diagnostic System 2, that is for 1996 model year and later) turbocharged cars to run on E85 have had very good results. Experiments indicate that most OBDII-specification turbocharged cars can run up to approximately 39% E85 (33% ethanol) with no MILs or other problems. (In contrast, most OBDII specification fuel-injected non-turbocharged cars and light trucks are more forgiving and can usually operate well with in excess of 50% E85 (42% ethanol) prior to having MILs occur.) Fuel system compatibility issues have not been reported for any OBDII cars or light trucks running on high ethanol mixes of E85 and gasoline for periods of time exceeding two years. (This is likely to be the outcome justifiably expected of the normal conservative automotive engineer's predisposition not to design a fuel system merely resistant to ethanol in E10, or 10% percentages, but instead to select materials for the fuel system that are nearly impervious to ethanol.)
Fuel economy does not drop as much as might be expected in turbocharged engines based on the specific energy content of E85 compared to gasoline, in contrast to the previously-reported reduction of 23.7% reduction in a 60:40 blend of gasoline to E85 for one non-turbocharged, fuel-injected, non-FFV. The reason for this non-intuitive difference is that the turbocharged engine seems especially well-suited for operation on E85, for it in effect has a variable compression ratio capability, which is exactly what is needed to accommodate varying ethanol and gasoline ratios that occur in practice in an FFV. At light load cruise, the turbocharged engine operates as a low compression engine. Under high load and high manifold boost pressures, such as accelerating to pass or merge onto a highway, it makes full use of the higher octane of E85. It appears that due to the better ignition timing and better engine performance on a fuel of 100 octane, the driver spends less time at high throttle openings, and can cruise in a higher gear and at lower throttle openings than is possible on 100% premium gasoline. In daily commute driving, mostly highway, 100% E85 in a turbocharged car can hit fuel mileages of over 90% of the normal gasoline fuel economy. Tests indicate approximately a 5% increase in engine performance is possible by switching to E85 fuel in high performance cars.

You could take the belt off, and take it to a Napa. Ask them to find a belt that is the same size as the Kenne belt.

The body is done with the truck but i've only just begun building the winch bumper. I was going to wait until I had it built and installed. I've been back and forth with hemifever and I think we are almost where the tune needs to be, I'm glad he is patient. Just fixed a belt slipping issue, wow what a difference. Broke the truck loose on a wet road at 45mph, gotta relearn how to drive it :-D

can you even get the boost a pump anymore? Last time I actually gave a half serious thought to a blower was a Kenne Bell kit someone was sellin. I contacted KB and was told no Dodge kit specific parts were available, this was about 4 years ago. As I have said time and time again, these blower kits are for sale for a reason. They are finicky when workin right with belt slippage issues and on the Dodges (other brands are hassles too) are a pain in the tail to get in tune. I would run stock injectors and rely on additional injectors for the added fuel, otherwise you'll probably be runnin pig rich all the time and still may lean out on the top end.
When I had my turbo Omni my super 60 pcm was good for 18psi of boost. When I wanted more boost I ran additional injectors (cold start injectors off vw's) hooked up to pressure sensitive hobbs switches to feed the extra fuel. I had 2 injectors mounted in the intake plumbin right in front of the throttle body, they were each good for 4 psi and I never did have any detonation problems on that car. So I could have probably eked another 1-2 lbs of boost out of the thing. Thats the route I would go and closely monitor things via a good EGT guage, air fuel ratio guage etc. make sure to play in baby steps keepin a close eye on all these parameters and back out at any signs of detonation.
Honestly for the money you'll have in this and possible aggrevation, you could have one sweet nitrous system setup. good luck

Extra injectors are a poor way to go IMO
I'm running 60lb'ers on with a 2 bar map. no trouble with it being too rich, actually took a couple of tunes (SCT) to get it out of the lean.
It took a couple of tries but I'm very confident i've conquered the belt slipping issues.
Personally i'm not a nitrous guy. I'd like it as an extra but I'd still very much rather have forced induction
I will agree with you on ....
Monitoring everything with gauges
Getting it tuned it takes TIME
nitrous makes power :-)
