Help!!!Whipple Supercharger with KB electronics???

[Anders]

I just picked up a Whipple blower on e-bay for my 2005 Yukon Denali, but it did not come with electronics. Can I use KB's newly released piggy back replacement?

 

What can I expect in terms of power increase? Can I expect 450 hp? I am supposed to have 335 stock... (The Yukon has the 6.0L Vortec engine)

 

I used to drive a F-150 Harley truck with a Intercooled Eaton M112, which I changed pulleys to provide roughly 10PSI (always Sunoco94 octane, and Michigan wheather), without any tendency for detonation, or pinging. However, I was lacking a little bit top end on the Roots blower, which I hope the screw will give. Hence my decision not to go with a Magnusson/Radix or similar.

 

What is a safe boost range with the 6.0L on the Whipple, without Intercooler? No racing, just "normal" driving.

 

Thanks in advance,

 

Anders

 

PS I will install myself, but if I change my mind, anyone know any good installers in Michigan?

Anders,

The piggyback FMU with the extra injectors is crap. You will have nothing but problems with it. Get 43LB HR injectors and a Wester's tune. No add-ons, just done right the first time! 6-7 lbs is a reasonable boost. Lyndon will leave some torque management in on the shifts to keep the tranny alive. You still should consider at least a Corvette servo.

Thanks for the info Butch. Not really what i wanted to hear, but I need to understand the best way... So no FMU, just upgraded injectors and a custom tune of the current PCU???

 

BTW, thansk for the feedback on the Autotap. Looks great. I still might just throw the OBD data on the Head unit for a slicker look. Where did you find your auto enginuity?

?

Thanks Anders

I bet the custom tune along with the big injectors won't cost much more than the KB computer and the exttra injectors. Many guys have problems and poor performance with these piggyback systems, and they do nothing for torque management, tranny shifting or speedlimiter. Wester's will address the whole package and make it run right.

 

http://www.AutoEnginuity.com is the site for Auto Enginuity. The biggest problems I had with the Autotap was the slow sampling rate of only 10 frames a sec (A/E is 40) and the limited sensor list. Had allot of software glitches too. A/E is way better!
