We need something new to talk about.

Recommended Posts

Randy, I built one simular to that a while back. worked pretty good. but the nice part of the deal was that the reeds lasted much longer. Since that was back before the sport jet reed cage that was a great feature for a motor to run on the river.

This is a cool project but it would sure take getting use to turning around and not seeing an outboard.

Good luck with the project. If this works, how about we put one in my 22ft toon? :o I need something to go after Iverson with! LOL

B-RAD

B-rad, this winter you'll definately have the faster sled, but come summertime that toon is going to be lost in the roostertail of the new "Partybarge 2". :lol:<_<

Hey John whats up, got a new toy?

Ya, as soon as I bought a faster Toon then him, he had to open up his wallet again! LOL And thats one big ass wallet eh Johnny! :D Post some pics of that ghetto cruiser you bought! :o

Back on topic -

RP, what boat is going to be the prototype? Something a little older to experiment with? Anybody have any pictures of the drives you are talking about using off this motor?

Re: Alpha SS uppers.

Some local guys here ran Alpha AA lower units with their Small blocks for years, 500-1100 HP and went through at least 8 drive gear sets a season (and in Ohio that season isn't very long). Blown out upper gears, cracked housings, you name it, they broke it over and over and over. Kinda made sence when they went to the BlackHawk (also discontimued). Also, Alpha SS parts are limited now that they aren't made anymore.

But the chevys have 4 times the torque at 1/4 the shaft speed. The Alpha SS upper is actually OVERBUILT for this application. Besides, who would think I (I never liked the word stock) :P would run stock gears? :huh: Truthfully I've sourced a manufacturer that will make me whatever I want.

that is exactly the tech we need for boating randy!! im really glad to see you working on it as i have a lot of respect for your knowledge and dedication to this sport and engine tech in general..

i have an '03 suzuki gsxr 1000.. it makes 162hp at the crank and like 155 or 158 at the rear wheel.. it has a primary and a secondary injector, with the secondary acting similar to the way they(secondaries) work in a 4barrel carb.. the entire bike weighs 370lbs dry so i know the engine is light although maybe not quite as light as this one your working on... i have been turning this particular gsxr up to the 13k rpm rev limiter for the last couple of years with not a problem-- 29kmi to be exact!!! its said they can move the limiter up to around 15grand and not have any problems also..

i rode this bike to florida and back from here in upstate new york, i averaged around 110mph on the speedo on both of the 1.3kmi trips, although there were times i was running much faster for extended periods.. oh, and then there is riding in daytona during bike week and sitting idling in 90+ weather with thge fan kicking on at 225 degrees also!! -- needless to say this motor has taken the abuse in stride, like any of these street bikes do, which is definately another plus along with the performance and weight..

oh, do you have any of those 2.5 intakes left?? have you tried it on any of your z-port motors?? just wondering how it does on them or if you have any expected gains compared to the stock horn.. keep up the good work! thanks

hey chris, i have an a15 at this moment but not for long hopefully...

i actually got the low down on setting it up from randy as i have no experience until now with this particular engine.. well, aside from putting it together and using carbs last fall, just so i could try it once before the lake froze!!

i am looking for an A48 for it, hopefully i wil find someone looking for some other parts and willing to trade or even if its a good deal then i could pull it off right now....

i have only fired it up in the shop so far getting it timed and it sounds really mean.. i will hopefully find a digital ecu soon, even if i have to change chips that is fine...

oh, and chris, this is not a gpi z-port.. it was actually sleeved by someone other then randy or jim ruck but i have talked a bit about this motor with both jim and randy.. a nice job was done with it and all the port heights are the same- and also not too high either... it should scream

I'll be able to give you some firsthand information on Randy's Z-Port with the GPI intake in a few weeks. ;) He's building a pair for me now! That GPI intake looks awesome, doesn't it!

I'll be running PCUs.

that sounds good chris, id really love to hear your thoughts and any difference from before. the intakes do look hot but the only thing that matters is their performance(which im sure is exactly what the man has said), anything else is a bonus i guess.. im not used to having a sweet looking boat/setup but i guess i have to with the pro comp..lol

id like to hear about your engine's performance even without the intakes.. have you run the engines yet?? im sure these engines are more then impressive from what i have been told by numerous people-- esp twins!

the most impressive part to me is not only the hp and torque they make, but that they do it without revving beyond what i feel to be a reliable rpm range-- seems like the ultimate lake motors..

im hoping to get one more of these z-port engines as i may wind up selling this one.. i already have a new one lined up to be built so if mine sells i just will have about 50hp less for a bit..

thanks again chris, im looking forward to hearing anything you have to say about the intake and motors...
