650 cid Compound Marine Engine
Boat motors are simply unique. Simply ask Alexi Sahagian, proprietor of Boost Power USA. He assembles 700-1,500 strength marine motors throughout the day, consistently, and making them live in a marine application is work No. 1. Alexi made the marine motor one stride further with his work of a 650 cid compound motor, which highlights two turbochargers and two superchargers.

Numerous motor developers assemble incredible motors. In any case, relatively few motor manufacturers can fabricate incredible marine motors. This is on the grounds that numerous motor developers neglect to sort out some way to get motors to live in boats because of the multitude of components that go with it.
"Boats are simply unique," says Alexi Sahagian. "They're under burden 100% of the time, so the motors are assembled looser than a car motor. Your bearing clearances are a lot greater. Ring holes are greater. Cylinder to chamber divider clearances are greater, and so forth In the event that you put a car motor in a boat, it won't most recent 60 minutes."
Fortunate for joy boat and seaward boat proprietors who incessant Sahagian's motor shop, Boost Power USA in Newbury Park, CA, Alexi has more than sorted out some way to make marine motors live. His motors live quite well and perform as far as possible. Alexi Sahagian grew up around race boats and used to help his father deal with race boats intended to pull speed skiers.
Those early days assisting his with fathering moved toward road vehicle section hustling when Alexi got somewhat more seasoned. A kinship with Tom Nelson of Nelson Racing Engines likewise filled Alexi's enthusiasm for motor work.
"Tommy Nelson and I grew up together in secondary school and we would go road dashing each Wednesday and Thursday night," he says. "Essentially, he went car and I went marine. We experienced childhood in Thousand Oaks, CA. I attended a university around evening time in Santa Barbara and began my organization, however I needed to get a higher education also, so I was doing both."
Alexi began Boost Power USA in 1986, yet due to being in school, he truly launched the business in 1990.
"A large portion of our stuff is seaward joy boats," he says. "In the mid '90s we used to oblige the racers, yet they changed the standards and the classes so much that we pulled back from it and chose there's far more numbers and volume of dollars in the retail market. We produce motors from 700 to 1,500 torque consistently here for seaward boats and delight boats.
"We do motors, yet we additionally construct injector packs, supercharger frameworks, we do all the strong works plan of every one of our pulleys, parts and pieces in-house. We have practical experience in the joy boat from 22 to 44 feet in every single various manners. We likewise accomplish total gear work."
Lift Power USA has 12 workers – including Alexi's better half, mother and sister – and is around 30,000 square feet with the capacity to do everything in-house. The shop has three dynos, a wide range of test gear for injectors and stream seats, and the shop's unique office situated down the road houses the machine shop with one committed worker.
"Everything he does is the filthy work – exhausting, sharpening, decking and adjusting," Sahagian says. "All that at that point gets moved into here and we amass here."
While a significant part of the joy boat market uses enormous square Chevy power, Alexi fabricated himself a marine motor that is somewhat not the same as the rest.
"Normally it's some custom reseller's exchange billet block, Chevy terminating request or LS terminating request, 540 or greater cubic inch and ordinarily fuel infused and supercharged," he says. "That is the most widely recognized thing. At the point when I was a small child, my shop was at my father's shipping yard, and the old Detroit diesels were compounded – they had a supercharger and a solitary super. I assembled an earth form of what I figured a cool motor would be with a major supercharger and two turbos taking care of it. I didn't generally have a clue whether it would work, yet I figured it would on the grounds that the military was utilizing them in plane spiral motors. That was the point at which I was 13-14 years of age, I actually have the earth model. At that point I developed it."
In 2010, Alexi constructed the first. Today, there's five of these compound marine motors, and they produce somewhere in the range of 2,500 to 4,500 torque!
"The innovation in them is truly slick since you can have numerous force bends in them on the fly in light of all the electronic wastegates and tunability that the ECUs have," Sahagian says. "You can likewise run various fills.
"Individuals consistently ask me, 'Do you need to do all that to make that power?' The appropriate response is no, we can do it with two turbos, yet when you drive a particular boat, similar to a little 21-foot V-drive with a compound set up in it, the quickening is so unexpected it merits each penny. Obviously, you needn't bother with the entirety of that, yet the elements of how you move the air is something basic to drivability."
"It was planned as a dragster type boat to go buzz around," he says. "The boat producer and I chose this motor would be a decent decision and protected to run in a boat this way. Typically, we run it in the 1,200 ft.- lbs. setting, since it's bounty quick like that. It has 240+ hours on it now. I don't have a clue the number of folks can make that sort of intensity for that long.
"On the first one, we do a ton of dismantling, taking a gander at it and assembling it back. We haven't dismantled mine yet and neither have we dismantled the other three or four out there. We're learning as we go."
Alexi's compound marine motor turns over with a 650 cid, all-billet aluminum block. Lift Power does all the strong works configuration in-house and the motor has CNC-ported Brodix BB4 aluminum heads. The essential set up remaining parts a traditional large square Chevy-type motor, however that is the place where the similitudes stop.
The motor has two 90mm Turbonetics turbos on it taking care of two 112H Magnuson superchargers that are changed on Boost Power's own projecting and intercooler set up with port infusion.
"It'll make 41 lbs. of lift, yet the motor is just 6:1 pressure, so it's extremely low and truly calm out of gear as well," Sahagian says. "We CNC planned the square, yet it wasn't worked here. At the point when we got the square, we machined all the cushions on the front for all the V extras, dry sump frameworks, drop sections, switch alternator sections, cam trigger, wrench trigger, and so forth The valve covers were machined here. The admission complex and intercooler Y complex are casted parts that house two superchargers for our creation 900 strength motor. We utilized that as the admission and afterward we planned a wraparound consolidate plenum that has all the wastegates, pass over valves and bleeders in it for the framework that are controlled electronically by means of the ECU, which is an AEM Infinity.
"The fumes lodgings and the headers are water jacketed. Each cylinder is water jacketed 316 treated steel. The headers alone resemble $20,000.
"Inside, we have our own driving rods made in Germany. They're EN30B billet. Same with the interfacing bars. The cylinders were made by CP for us. The fumes valves are all Inconel and serious obligation tempered steel for the admission. We utilized Clevite covered H-arrangement orientation. The motor has a Jesel belt drive, rockers and lifters. CHE made the lifter sleeves. It has specially designed bracketry to expect all the triggers to remember. It has a dry sump skillet and a Barnes dry sump 4-stage siphon."
Lift Power likewise has an organization under its rooftop called B2 Superchargers, which gives the superchargers to Boost Power's fundamental business.
"We purchase the rotors from Magnuson, which are Eaton 112H rotors, and afterward we make all the castings and the noses for that set up for our normal creation 900 motor," he says. "That is the rotor bunch that we have in this motor as well. We likewise have altered seals and oiling frameworks since we're pressurizing the supercharger, so we've needed to make a few mods there.
"This motor sudden spikes in demand for liquor, e85, 100 octane, 89 octane, 87 octane – it has around 12 settings in it – those are the most well-known ones. It's sort of like a diesel tuner – you can pick how you need to run it. I for the most part utilize 100 octane since it's anything but difficult to get, it's acceptable around the water it actually makes a lot of intensity. It's our moderate setting, however it actually pushes that boat very great."
As the 650 cid compound marine motor sits today, it has turned out 2,448 hp, yet Sahagian says that is moderate for this motor. In its moderate, 60% territory it siphons out 1,500 ft.- lbs. of force, yet could give as much as 2,200 ft.- lbs of force. These force numbers convert into Alexi's 21-ft. Schiada V-drive race boat hitting maximum velocities more than 150 mph!
