What are the blower guys using for tuning?

Most are using a VEC2 or 3. VEC stands for "Viper Engine Controller".

this thread makes no sense, they are two entirely different animals here.
A SC'r is simple , cheap, easily upgraded, reliable, but can only go so far without getting exotic like blake did.
A turbo will make the most amount of hp with no loss, and very reliably also, but with the right combinatiion.
Power in the two is also two completly different animals.
If you are wanting top end power for top speed then the answer is simple, you need turbos, the power never stops, a SC'r is definitly not for this, it is limited by the engine, plus the crank is your weak link.

superchargers rob a little power due to belts, but turbos rob a more power due to exhaust backpressure. so what's the difference? they all add power in the end.

Nope, no beer tonight son.
I was looking forward to this because I wanted to see what people had to say.
Actually some folks have done very well with their answers.
However after reading what he wants to acheive, I have to agree with Stinker. You want to go the Turbo(s) route.
However it should be noted that Turbos are not free HP. They have their downside also. Back pressure was mentioned. What was not mentioned was this back pressure also retains heat in the motor. You need to be sure not to retain to much of that heat in the engine. Not that hard to accomplish, but you do need to be sure to account for it.
While I'm on a roll here I may as well mention something about boost pressure. The boost PSI is a factor of restriction within the intake system. The air cannot flow freely so it backs up and that becomes your boost pressure. Make sense? Well look at it this way. You can have two identical engines in regard to compression ratio, cam, and for this scenero blower. Only difference is that one engine has stock heads and valves. The other engine has ported and polished heads and larger valves. The engine with the modifed heads will not only have a lower boost pressure, but it will also make more HP. Why does it have lower boost pressure and more HP. It's because with less restriction in the intake system the boost will be lower, but because it can flow more Air/Fuel mixture into the cylinder it will produce more HP.
Oh hell, one more thing. Well two actually. Be sure to install a cam that is designed for boosted applications. Also lower the compression ratio down to at least 8 to 1.
Have fun and good luck.

Isn't that what the STS kit comes with?
TurboFreak said:
No the STS comes with a STS-1E. It is like a VEC2 but it only controlls the extra 4 injectors and it can trigger meth. A VEC2 can control all you injectors plus do a bunch of other stuff. I think of the STS-1E as a mini-VEC2. (In my Dr. Evil voice) It is 1/8 the size of the original VEC2.

STS uses a box similar to the VEC, but it is not the same (it's a proprietary box only for the STS).

I think I'm in a different time zone, you have to account for the lag.

If you bought the VEC2 instead could the STS system work properly? What injectors come stock in the SRT-10? lb/hr? Style(EV-1, EV-6 etc)? Length? MOst Dodge vehicles now run a fuel pressure of 58 psi. Is the viper also rated likewise?
TurboFreak said:
You bring up one of my next mods. I have talked to great extent with Roe Racing and with STS. For a while I was tradding emails daily with Rick Squire. But to answer your question Roe advised me to get the VEC2 (now it would be VEC3) and bigger injectors. Then the VEC3 would control all the injectors (both engine and turbo). I'm not sure as to the size of the stock injectors, but I know you can upgrade to 42 pound injectors. So the stock ones must be below 42.
Stock injector are around 32lbs.
I have a set of 60's if anyone is interested, and no they arent too big, you are only using a percentage of the injector
