The breakdown of the 26's thru the range is over on the other thread, but top end was 5200 @ 77-78mph speedo. BTW, late last year I had a chance to try stock 27's. They ran 4900 @79mph speedo. I have labbed 27's on the way. (gps has confirmed that my speedo is "off" by 2 mph at top speed).

Thanks for the data 29 Outlaw. You'll have to post your results with the 27's when you get them back. Good luck!

Gettin Bye, I did not have my speedo hooked up at the time I will be doing some testing this weekend and I have my speedo hooked up now. I picked up a set of 23+ and will be tring them both ways as well as my 25+ and I'm going to borrow a set of 24 bravo's to try so I will get back to you with all the imfo. Thanks for the help everyone.

Hey Advantage,

I had a chance to run the 25’s while documenting speed thru the range. I also entered the world of hi-tech and purchased a GPS to record speeds. They are below:

GPS

2500rpm – 33.5mph
3000rpm – 41.5mph
3500rpm – 49.3mph
4000rpm – 58.5mph
5200rpm – 74.8mph

Speedo

2500rpm – 33mph
3000rpm – 41mph
3500rpm – 50mph
4000rpm – 59mph
5200rpm – 77mph

I could have worked the trim and gotten a little more speed but it wouldn’t have done any good since I was running at the limiters. If Hill is able to get me 300rpm out of those 27’s then my top speed would be 79.6mph @ 5100rpm. I’m not expecting that speed but you never know. I would be thrilled with 77mph with the labbed 27’s. Nonetheless, they got me exactly 300rpm by labbing those 26’s that I tried a while back. Went from 4900 to 5200.

I got back my Bronson Hill 27’s and the results are below. All numbers are GPS and achieved on mirror-flat water with temps in the high 80’s:

Old 25’s:
2500rpm – 33.5mph
3000rpm – 41.5mph
3500rpm – 49.3mph
4000rpm – 58.5mph
5200rpm – 74.8mph

New 27’s
2500rpm – 33.5mph
3000rpm – 43.5mph
3500rpm – 53.2mph
4000rpm – 60.5mph
5000rpm – 77.2mph

I obtained the new numbers without activating my OTIS311 Turbo (AKA engine cover opened 2”). Someday I will use my OTIS311 Turbo but not today.

I guess I’ll settle for these numbers. It would have been great to see 78 since 78 can be rounded up to 80 for bragging purposes. Oh well, perhaps with the OTIS deployed.

We've been doing some testing on a buddies 29 and mirage 27 are the fastest at 80 on gps at 5300 26 bravo 77 on gps at 5240 and 28 bravo at 77 at 4800 rpm this is with twin 500 efi's
