Totally different boat. I love it!:rollside:
What did you do prior to whipple. How much did it give you after? Top speed wise? Any other mods? Drive? Prop?
I designed the boat around the Whipple. I had Howard rig it with a MAG HO and add an XR drive, IMCO dual ram steering & hydraulic helm, Dana 900 tabs, boost and fuel pressure guages. I broke everything in for about 10 hours prior to putting on the Whipple (about 1.5 hours were logged by Hot Boat for the Oct. O5 issue). I also upgraded the rocker arms. It used to run best with a labbed 25 4-blade and now uses a labbed 29 4-blade. It picked up a "real world" 13 MPH top speed, but more importantly, the acceleration is just awesome, from hole-shot on. The same boat with an HP 525 is only about 3-4 MPH slower but does not have near the acceleration. The package really came alive after some fine tuning with the prop (it started out life as a lab 30). For the way I boat and the lakes I boat on, it's perfect. (for now!)
