when i first went out i was not getting enough tail lift so i check all the setting. ride plate was way up and so were the cav plate. so i put the cav plates level and the ride plate to 1/16 up. i also machined the shoe from a tapered to flat.
i droped a valve and put a hole in the piston. on my thrid trip out.

now my question is where would be a good starting point for cav plates and ride plate. also would it be better to go to a cut back shoe?

bp will probably be a real good person to contact about your set-up as he's been racing a SW for a few years with real good success.
nice boat!

[JETBOY03]

thanks cas

[jet454boat]

hey man this is just something i noticed but it might not be that way, i see alot of water coming out of the headers, that may be why it dropped the valve, is it an exhuast valve

I agree. Bob's boat is one running mofo and runs well. He is at firebird EVERY year running good numbers;)

no it was an intake. i noticed the water also and turn it down. the valve that was in there is a 2 peice. from what i understand a 2 peice valve cant take the seat pressure of a roller cam.

thanks for the kudos:)
nice lookin' sw. what year is that? for some reason, that boat looks like something i've seen pics of before???
do you have any pics of it out of the water? pump/hardware/etc.?

[396_WAYS_TO_SPIT]

396, you need to come to firebird and pit for me with squirt'n... i haven't lfmfao so hard in years....
Ill be there for the finals;) We'll have to do a little bench racing :D

Welcome to the Southwind clan :D
Wasnt that one running on AV Gas? I think it was plumbed for Nitrous as well, not sure if it was ever run with it though.
Very nice to see more southwinds out there.
What MPH and RPM's were you turnin?
Attached is a pic of mine. They're alot of fun and Congratulations

[JETBOY03]

well when i had the gps on it, it went 78-79 at 5500 it will turn 6200 with b imp, but i couldnt read the gps. that was before i made some changes, but i forgot my gps after i made the changes so no new #'s.
yes it was plumbed for no2 at one time. and he said he was run 100 octane but it didnt smell like av gas.

[Squirtcha?]

Nice boat. I was eyeballing that one on spam. Looked like a good deal and I've always liked the SWTDs. Shame about the motor going away.

[JETBOY03]

here are some pics of the setup

now my question is where would be a good starting point for cav plates and ride plate. also would it be better to go to a cut back shoe?
I would start at 3* up on the ride plate and 2 * down on the outer plates

[Nucking futs]

What is the overall length of the shoe? from the pic,it looks to be a real short shoe. Might want to close off the intake alittle but would need to know what it is now.
Why would you take the taper out and run a flat shoe? What was the boat doing to make you switch? I would start at o on the plates.

i will get a measurement tomorrow. i was told that the flat shoe will help with tail lift. what would closeing off the intake do. this is all new to me i had a golden eagle before.

Might want to try blocker in the loader to get some lift. What was the boat doing for you to change it? From the spam add this thing was dialed on the set up..lol I would take it easy on the wheelies too. Not very healthy for that bottom.

[Nucking futs]

Also might want to read up, there is some good info on the boards,but you need to weed through all the bullshit.

Yeah thats a good thread, alot of BS though.

[cyclone]

yeah you gotta weed through posts like this one from jokers:
I installed a .030 shim on time, it was crazy. :)

naww, not on ***boat:) :) There is never any of that here :D :D :D

it was far from dialed. it had a blocker and i took it out to see what kind of a diffenence it made. i think i need to cut the blocker down a little. i changed the setup cause it was porposing really bad till i hit about 4000 rpms and the tail was real wet, also the blocker loader made it cavitate real bad on take off.

Welcome to the SWTD club. Unfortunatly they all like to porpose at low speed unless you tune it for cruising speed then you suffer the top end speed.
How much blocker was in it? I have about 8" in mine but its an R intake and the opening is alot longer then the normal intake.My set up is exactly what my dad was running in his back in the 80's and was running about 103-105mph in comp jet with 500 hp.
Get with bp but I would start at 2.5* up on the ride plate,0 on the tunnel plates and start with a 2.5* B/C shoe and play with the diverter for the nozzle angle.

Or even a 3 degree b/c shoe, they need the lift, shouldnt be a problem coming from a flat shoe. It looks like hes got the short shoe as well so there might be less effect from the b/c. Take it easy on the blocker if you want any kind of holeshot.
love that pic..

[JETBOY03]

thank you everyone all the info has helped out a lot on understanding this hull better. i cant wait to get the motor back in. nice pic Nucking futs!!

[bp]

both my mpd loaders have 4 1/2" blockers. my sw has never porpoised, either with the old lake 427 and speed grate, or with the current setup.

Thats becuase it weighs as much as an ocean going freighter....:D

What is your dads running for hardware Chris?

[Cs19]

What is your dads running for hardware Chris?
3 degree bc (short shoe), 2 x 1-5/8 loader, about 4-5 degrees up on the nozzle, 2.5 on the R. plate, cant remember where the cav plates are, i think 0.It runs about 85-90 with 600 HP, real fun to drive, carries the nose nicely but drags its ass through the water. It does porpoise while cruising but that all started when we were playing with the cav plates, we could get rid of it if we played with it some more, dad just runs it doesnt play with the setup ever.We are going to run it in RR one of these days.

Heres a couple of shity pics of mine.I am also still working on set and learning to drive it .http://www.***boat.com/image_center/data/500/medium/DSC00076.JPG

Like the new avatar:D How bout some pics?
Jetboy
Mine loves to porpoise (sp.) from about 3200-3800 rpm's and adjusting on the cav plates will only sacrifice elsewhere. Get used to it:D and keep it above
4k:D

[ol guy]

Those boats will take a sky shot off plain no matter what the set-up. That out of the way I raced one back in 1982 and the set-up came from Ron Hamilton and worked real well for a baseline, 1/8 down on the cav plates and 10 degrees up on the ride plate with a 3/8 shoe. the down on the plates took out any porpoise and helped trap air at wot. and your'e water should not be more tan 6 feet high at wot or you will drive the back-end down if you look at the old shots of the original going places and how it set and the size of the roost that will tell you. And by the way the original going places boat was a southwind 19 foot tunnel dragster and owned the record for awhile.

all the better for racin in whitecaps :devil:
and i'd suggest that most of those that are left aren't lightweights like the blue one. :)

i forgot to measure the shoe but it is short compared to my buddies. the blocker i have is 8.5" now.

What intake did you run? Ron could set them up real well but 10* up on the ride plate? I don't think so. Not all of them shoot for the moon on the launch,just depends on where your at on the hardware. comparing a riverboat to a fueler is apples and oranges and in '76 when they started playing with the SWTD the fastest Going places went was 125 and ran in the 9's with the blown fuel 489 Donavan.It took some years to figure it all out.
