Yes on all counts. They are not fast workers, but they do the job right. Jason has built 3 motors for me. The present motor is a 540 with a quad rotor Whipple EFI.

1000+HP Baby!!!

zt , i guess you be the winner in the "how bad you got it" catagory !

[Dave's ZT260]

Yeah- I know.

Could be worse-
Give me time.

zt ! what size fuel supply line are you going to feed this thing with ? did you say you run 2 different tanks for different octane ? i noticed i only have a 3/8's line now , although i have another capped fitting for a second motor

[senator-holland]

there is so much power that the engine + drive will go throug the hull of your ZT260 and leave you and the hull behind... lol http://www.checkmate-boats.com/infopop/emoticons/icon_biggrin.gif

1/2 lines and a 1/2 fuel P/U. I have two tanks 93 and 110 octane with a electric switch from IMCO. This setup should make 1000HP on 93 and 1200HP on 110. The XR drive will not last long. But I have a spare.

The hull will not handle all the speed I have on tap, so I may not need race fuel anymore. I figure 105mph will be the limit of "safety" I'll keep ya posted.

[senator-holland]

what is the max hp on the xr drive?

[Dave's ZT260]

As much as it takes to break it.

Seriously, Mercury says 600HP. So its hard to break one below that HP. Above 600HP you need a steady hand on the throttle. I never pull hole shots or hammer it at speeds under 70mph. And never never jump a wave without backing off. I ran 800HP with no problems. But now I am a little worried. She will be fast until she breaks!!!

zt ,,never thought about the p/u . just assumed i should use 1/2 in supply . you using anti siphon valves ?

i geuss just cruising around with your family is not your choice of a fun day on the boat.

[Dave's ZT260]

Not at all, most of the time this boat never sees 80mph. But when the family is on the island and some hot shot needs to be taught a lesson I take my brother and kick some serious but.

The P/U is the biggest problem for high flow systems. I have not needed any antisiphon valves. They just restrict the flow.
