"Building the Century Jet"

[LVjetboy]

Just had a brainstorm while posting the other board. Greg Shoemaker could do an article on how to build a 100 mph jet for less than 25k?
What do you all think...can this be done?

Sounds like a good idea....lets see what he can do for something let's say....21 foot long!

A 21' Jetboat, that does 100MPH for less than 25K ? I love jets but I know of only one way. Rent a really big Airplane, Insert Boat, Take it up to 30,000 Ft. and kick it out.

Now lets not be a doubting Thomas...Let the challenge begin!!!

Awsome idea! Real World jets.

Does that 25k include the hull ? Just kidding, it would be a stretch to run 100 mph with 25k spending cap.

Just bench racing but it would require a verrrry light 21 footer with a verrrrry straight bottom a verrry effecient jet and a grenade for a motor. by my calculations a 2500 lb boat would need about 900 hp to accomplish it without wind resistance thrown in. To make that kind of hp and make it live sounds like $30,000.00 plus in the powerplant. Current open Modified roundy round engines are about 200 Hp shy and cost about 10 K more. anybody got any ideas?

How about a stroked, Whippled SBC (around $12-$15K- 700? ponies on AV gas) in one of those stripped-down "beer can" hulls? http://www.goldenplasma.f2s.com/foru...confused43.gif

How about do it in a 18-19' V-bottom and be more realistic. In a hot V it could be done relatively easily. In a 21' jet... Better have some nitrous. A lot of Nitrous. Like two bottles. And a big motor. And a blower. And a....... you get the picture.

Guys the only way to accomplish this project would be to find something used. You could build a stripped down version less motor for the mid to low 20's but the we have to put a motor in it.Whenever I quote a new 21 or 19 it has all the horns and whistles for a number reasons. Speed means safety and good quality parts are a must. This also includes the engine. Maybe we should try to build a 100 mph boat for the min. amount of $$$$$$. Greg Shoemaker
