For what it's worth he did mention meth injection as stated above on page 2 post 16.


Thanks

Who's been negative ? I think it was more annoying to us that you had a fanboy jump in polishing your boots, but no harm no foul ! j/k Shawn

I'll just say this : your 1320 foot engine building abilities may be stellar, but its different from making a marine engine live a long time thats under load all the time, especially in a heavy non-stepped V hull. The amount of meth needed to make those live, in that boat, is going to be a lot.

The issue is, you are not the first to come on here excited about a project shooting for big numbers. Do some research. The guys you are talking to were in the same boat once. They built big power and blew up on a big stage. You are saying you are building the fastest 42 Tiger and your engines havent run yet. It will be fun to see how this thread progresses. Be sure and video/document the dyno and first run.

TxHawk ever seen our white 40ft motion TOP CAT run around the Clear Lake area ? I did the research years ago and in several different hulls. The motion is a big heavy boat but it runs pretty decent, hasnt been outrun yet and dont break nothing but the fuel needles.
The Tiger will be interesting, just depends how fast Doug wants to go
