I have more Turbo Kit questions. Before the flames start coming in please understand I am just trying to make an informed decision. I know most here like the RCC kit and say to go through PowerHouse and that is fine and quite possibly exactly what I will do but I have questions and would like some more answers before I shell out 5K for a turbo kit.
I spoke with both RCC and Mr. Turbo yesterday on the phone. Both seem like good quality kits but here are my plans and a few of my questions.
I have never ridden a Turbo bike before. I may get on a Mr. Turbo stage 1 classic and say oh my what have I gotten into and never want to fully utilize the power I have available. Then again I am a pretty huge speed and power junkie so I don't know. While speaking to Mr. Turbo (Sorry freaking horrible with names) he said they were dynoing a 600HP methanol busa for a guy for Bonneville this weekend and said he will only be using 450HP and won't know what to do with what he has already. Said that is scary fast at that HP. I spoke with him about his kits and options and failed to get the type of turbo he uses for the stage 1 kit. He did say for an additional 300 I could get the 450HP turbo with the stage 1 kit. So with that I do not know if I will want to go beyond 270HP ever or if I will want to run much more some day. If you see my previous engine build thread you will see that I am building an engine that will most likely take just about anything I throw at it.
So some of my questions now are.
1a. For a street bike am I better off running the smaller Mr. Turbo stage 1 turbo when it comes to building boost faster and making a better street performing system or will the 450HP turbo that the RCC kit comes with or that Mr. Turbo will sell for an additional 300 on the stage 1 kit be just as good and spool up and act just as good?
1b. Where does the Mr. Turbo stage 1 turbo start making boost compared to the larger 450HP turbos?
2. The Mr. Turbo Stage 1 Elite comes with the billet plenum ready for secondary injectors where it takes a RCC Stage 2 kit for the same thing unless that is an addon. I understand you still need the secondary ECU and the Injectors but it would be ready for the install.
3a. Do you think street bikes need a Blow Off valve? According to Mr. Turbo the answer is NO. He says unless you just want to hear the noise it makes to sound cool its a waste.
3b. I see that both RCC and Mr. Turbo both will sell you the Tial 50mm blow off for well over what you can find them for is this because of a needed modification to the system like a flange etc?
4. I posted another thread about bigger injectors vs secondary fuel rail. I see it both ways but the turbo stage 2 kits all seem to go the secondary fuel rail route instead of larger injectors why is this?
5. I keep seeing that the turbo is mounted where the stock oil cooler is. What happens to the oil cooler? Does it get moved? Removed? I see the Mr. Turbo Stage 1 Elite comes with an Oil Cooler Kit is this so that it can be mounted elsewhere as the stock one has to be removed?
6. If I install the PowerCommander hub and GM 3 Bar sensor what benefit will that give me? Tuners all use the Dyno O2 sensors correct? Or will this be to help the Dyno tech to tune the engine better?
7. Is there an air to air Intercooler kit that anyone sells for the Busa that will allow you to keep the stock look and headlight etc? Or a water to air system?
I really just want to make an informed decision before I lay out the cash on a turbo kit. So please don't just blindly say "Go for the RCC with PowerHouse" unless you have words of wisdom as to why I should go that route.
I am ready to place the order as I would like it to come in around the time the motor is being installed and I know there is at least a 3 week lead time for both kits.
