24 pantera etc. what kind of speeds from how much power?
 

mine is a TRS boat now, but probably won't stay that way for more than a year or two. probably getting 450 or so hp jumped-up L29 for it's first engine. just wondering everything from 260-alpha to about 700 hp-high xdim-imcos and even a few arnies have been put in these hulls. just wondering what the end results come out to. edit; tomas wallin's numbers don't count. i don't have 5 years to blueprint my bottom.

I have TMONE's original 24 Sport. 509BBC, 575hp with Bravo 1. 80mph running a Hydromotive P5X 15x25 at 5800rpm's. Some of the gear heads say there is more to be had from this setup but 80mph is plenty for me. LOL

I had 560hp in an 1995 24SE, spinning a 23M+ approx. 5700rpm.
I saw a best of 75, but the next few owners saw closer to 78-80.

you know, with a few samples we might be able to create a speed-hp calculator since it is a pretty big cross section of very similar-i hate to say identical-hulls.

I'm hoping to get my junk into the high 80's.
Projected HP is 650ish.
I flipped my hull and straightened the bottom to the best of my ability.
Time will tell, I suppose.

V.C. werent you in touch with Tomas when you did your bottom or maybe I have you mixed up with someone else? Your pictures look great, we are looking forward to hear how she runs .

I didn't corespond with Tomas but I read his thread more than a few times.
I'm sure my hull is heavy as its a really early one.
Hopefully, by this summer, I'll know.

Thanks for the compliment.

24 Pantera TRS mirage 23p said to be 400-425hp would flicker 70mph light fuel 1 person. Two people with fuel 68mph was the norm.

took glance at your build thread. warmed over 330? that looks like a rect single plane intake. still oval heads and flat pistons?

My post was with the old setup. New setup hasn't been propped or run hard yet.

My 1999 ran 75-76 mph with the Innovation 500EFI. Had the heads rebuilt and ported by Veleko and it then ran 77-78 with an all time best of 79.6. I am guessing the freshening and porting added 30 hp or so.

Is that the one on the you tube videos? If so what a sweet running boat!

With a 540EFI - pushing around 625HP I hope to get that little 99 up to 85 mph once i find a prop that works.

Yes that's the boat. Several videos on youtube of the boat running in Fl, CT and NY.

406ci SBC with TRS and 19P Mirage 68-70 in near glass like conditions. Only made it to Lake Michigan once last year in 2-4 footers and was hanging on versus looking at gps on my phone haha. I've heard from previous owner mid to high 70's in chop.

Man, what kind of RPM's are you turning with only a 19p prop to get those speeds!

fired up an online prop calculator. 6500 with 8% slip. 6900 with 12% i hope he doesn't have the short oem 400 rods...

It's been a long winter but yes I would say it is spinning 6200-6500. There's nothing oem left on this 406. Just had a rebuild last winter and the guy did an awesome job. It runs perfect! I forgot to mention in original post its around 500hp maybe a bit more. Never had it dynoed but with the parts/ specs its a good estimate. It was originally a small block boat rigged at TNT Marine with a 400 small block from United Racing Engines I believe. Original motor is no longer in the boat. It met its demise years ago.

This set up is good for 80 . . . .
