Centrifical builds boost slow. Very little boost at lower rpms and makes all its power and torque specifically at the higher end. Roots blowers produce torque and horsepower throughout the rpm range. And dont kid yourself Tom. There are plenty of failures....you just dont hear about them as it is a huge conspiracy. Don had nothing but Vortech and a BAP when his timing tensioner let loose. Timing went crazy and lucky for him nothing internally broke...but it sure could have. Also at this point Don either has to get additional tune programs for when he changes elevation or lift and short shift to avoid causing damage that would require major repairs. I dont know about you but I dont want to have to think and or light foot my car to keep it from exploding. The conspiracy regarding tuning is kind of swept under the table as no one wants to bad mouth anyone else. All I will say is look at Teds pistons. And talk to him personally. Sure maybe he should have had fuel delivery upgrades...but it was not even suggested.....I am seeing this new trend happening with several other engine builders and tuners out there.
The are being straight and honest and building these SC units the right way now. If you look at GM Performance parts or talk to them about a SC on a LS3 they will tell you straight up. Must have internals. Must have different gaskets, must have different head bolts etc. No ifs ands or buts. Talk to LPE, or Hennessey...SC applications Must have internals, gaskets, bolts.
Talk to Brian....SC applications must have internals, gaskets, bolts or be bone stock with no additional power adders...none.! Buy one from Clint at Air And he will make the proper suggestions and be persistant that the proper supporting parts be installed or he has it in writing on your paperwork that it was declined. These guys all know the right way to do this. And they are not out to make 300 to 500 on a SC (if that cause margins have got so tight) and labor to slap them on and put someone in a position that it will break.
Yeah I am on a soapbox here. But everyone needs to know a SC with any additional power adders will require several major supporting parts. If dependability is a concern. I can go round and round discussing BAP systems vs dual fuel pumps but I will guarantee which will be safer. Overvoltage operating a pump beyond specifications and putting 20K motor at complete risk..come on...that is retarded for the 6 to 700 difference.
Ok now that is out there...How about those Pats...lol
