To Titus or not to Titus, that is the question that I ask of thee

[Wild Bill]

Got an 89 ally xr 2002 with svs drag and sportmaster 8" setback, Using a 14.5 x29 hoss HPD. Just asking if anybody has experiance with the Titus welded cone mod on a setup like this. Not that i do it often,but at speeds over 110 mph GPS i get weird driveability,namely it tends to drop the bow and in general hop around no matter the engine hight. Therefore it has never ben WIDEOPEN witch i would like to do. I have ben thinking about this for a couple of summers but i dont see much written about this. What i have seen written about are about boats that can only go100-110 on a good day. I guess what im asking is will this mod work in the 120-135 mph range with out blowout. The sporty has always ben a turd in boat flight abilliaty compaired to my old coned 200 case. Id hate to go back ot paint and bondo maintenance if the driveability are not worth it Thanks in advance.

Bill ,
I'm not an expert on driving the ( canoes ) Allisons BUT the people I have and do sponcer in racing tell me that when the bow drops on the big end the motor may be a tad high. Might move the motor down an eighth of an inch or so. I read that you said you've changed height BUT some times moving more than an eigth or even a sixteenth is the sweet spot and a quarter is TOO much..I have also seen slight mods on the skeg on the torque tab side bring them around too , dunno know your set up I DO know that set up such as , weight distrubution, gear case , trim angle, motor health and position and prop choice can make all the difference in the world as to how your "canoe" will handle top end speeds.....

IMO if I were going to make a nose cone alteration I'd try Bob's they do a great job, have proven performance numbers with the Allys and they are a Supporting Vendor of Scream and Fly promoting this site and the sport of High Performance Boating...

Good luck,
Happy Holidays,
Jay

You might want to invest in a million dollar life insurance policy to help out your dependents before you try the run . Please talk to other Allison Top End guys first ! From what I hear you only get one shot at having it right !! Be careful !:D

[MODVP22]

Not questioning you, but are you sure you're running a Hoss Hyperdrive prop and not a Hoss Triton-had a Hyperdrive and those are built for BIG bow lift, the Triton by Hoss is their claim to fame from Allison speed and performance.

You may want to try the Allison Owners board, I know this has been asked many times for the Allison drivers.

Where are you located? Lee Sanderson in Virginia can do some magic on that sportmaster. I have run a case done by Lee and a Titus case on an XR2002 and I prefer the handling of what Lee does. However you will never get a sportmaster to handle like a 200 coned case for your "top end" runs. The sportmaster case is just too "big".

You mite want to try sending Jeff Tyner--xrallison--a p.m. I am pretty sure he runs a Titus coned sportmaster, and runs VERY FAST!!. I run a 200 case with CLE guts and a bob's cone with a blow out ring. It runs very good into the mid teens. Only been over that a couple of times(122.3) and that was with a XR-4 case with a bob's cone, back when I was MUCH younger. The XR's ar very funny about the cases you run but, are also very predictable. If they "dip" the left side at, say,110 it's been my experience they will do it at the same speed every time. Also like someone else said, I'd try a Hoss Triton if you can get your hands on one. The XR's LOVE those props! Good Luck BE CAREFULL!!! Mike T.

[Wild Bill]

thank all of you for your responce yes its a hpd prop. bought new. this just opened more cans of worms for me to think about . I have hyd jack so i have fiddled with hight till the cows come home. Not woried about the absolute top speed but the driveability at stupid speeds

[Wild Bill]

would be interisted in talking to lee do you have a number

[Jay Smith]

Lee's a GREAT guy and VERY smart about the "Canoes".....

Jay,
I didn't know you didn't know how to drive a real boat! I knew you liked those training wheel boats but to call a mans boat a canoe just might get him steaming under his colar, LOL!!!

Wild Bill,
Call Robbie Patterson @ 804-706-1847. He took over my prop and unit mod part of the business in 2001, he is still located on our primisis.

Well I run a Titus coned (cone placement how i wanted it) 200 case w/SM internals and love it ...... 126mph and its as solid and smooth feeling as anything I've run. I too do not like the SM at all at higher speeds though I've not run one on my Allison but don't think i ever would

[Corona Mike]

Jeff, did you have to run a blow-out ring with the cone for those speeds? Mike.

[David]

Wild Bill who used to drive record setting boats for Jaco's?

Chigger Cissco Mite have spelled it wrong but, thats close.;)

Its just a very sharpened stock ring on the case it self.

Jeff what I'm talking about is a extension the other way toward the prop. The Bob's cones on the XR's would drop the nose at around 110 (actually 108;) ) without a blow-out extension. Just curious what Titus does different.

[Wild Bill]

me too.

[Jeff "Yammer"]

Nope ... mine is all stock there !!! I have no lip on my Allsion either though ...

[Corona Mike]

Mine doesn't have a lip either--it's a 88'--the only thing I can figure with out looking is you said he places the tip of the cone 3/16" lower than C/L of the prop shaft, and the cone mite be a bit longer. Other than that I wouldn't know. I know if you add the B/O ring on the Bob's 200-case, it will run 118+ (thats as fast as I've run with a 200 caes)Sounds like--as I've heard before--the Titus case is the way to go!

[esdbass]

Not to talk about something that I don't have personal experience with ( Ie an Ally ) but I think Titus can help you certainly a lot over a stock Sportsmaster. There are a lot of options and a bunch have been mentioned here the XR case with a foot, the 200 case with a foot or a modified Sporty. One hasn't been mentioned and that's Titus's Sporty with the full modification where he cuts the nose off the stock sporty and then puts another foot on.

Recently he has been able to get Kurt Mour's Stroker with a 300X to 109+ which was up 5+ MPH from a stock Sporty. I have personally driven both of Titus's Sportmaster case modifications and think they handle and track very well. They make my boat, a Stroker handle much better and run faster 101.08 best so far with a Stock 250 XS:)

[Jeff "Yammer"]

Yep there alot of things you can do to get one of those pigs to run hard. They're not straight and they're way to thick in a few different places ..... I've done a few and still kept the stock cone ..... alot of work .... over 12hrs on the last one and it gained in handling and top-end ... !!

Skip it.
Maybe works on Strokers and other types of hulls.
