Hey guys and/or girls, Ive been reading threads all over the net and the people here really seem to know there stuff when it comes to turbo jet boats. I’m a new member to the site but have read a lot of the threads. Been playin with jet boats for about 10 years n have finally decided to go with an EFI single turbo setup on my ’78 Cobra Craft. I’d like to get some input on selection of Turbo, cam, wastegate, POV, Bonnet, Intercooler, ect from people with experience. This is my first Turbo build and here’s what ive got so far.
Engine – BBC 454, 118cc rect. Iron heads 2.19 int. 1.88 ex. open chamber, 1053 forged crank, gm forged pistons (3999295 casting) 9.25:1 with my heads I believe. 7/16 forged rods, ARP rod bolts/ head studs. Crower cutaway solid roller lifters.
FAST XFI red box 160#/hr injectors, 2150 cfm throttle body. The goal is 1000 hp/torque at a reasonable rpm like 5800. it’d be awesome to get some ideas from some pros – Haas, Info, Unchained, GN7, I’m sure uv got ideas.
