Fixn to turbocharge my trike, for cheap!

I am not a turbo expert but hopefully the info below will help you some.

TURBO SIZE

You want an IHI RHB31 turbo which is the smallest production one available, but they are expensive . . The one in the link below is a Chinese turbo p/n VZ21 and is a copy of the IHI unit and the bearings may not last long since they probably only cost around 23 cents, however, they are replaceable . . These guys simply "borrowed" the charts from the IHI site . . See price at bottom of my post.

CARBURETOR VS TURBO PLACEMENT

1. you can run a carburetor before or after a turbo . . Before is called a draw thru type system and after is called a blow thru type system.

2. Running the carb before the turbo is far easier to set up and jet.


CARBURETOR

1. I would run one that is larger than normal.

2. You will likely need a needle with a large taper.


COMPRESSION DETONATION AND IGNITION TIMING

The more boost you have, the higher the compression will be . . If your engine has around 8.5 static compression and 5 lbs of boost, you will have around 11.5 compression.

If it pings, you can run higher octane gas or reduce the amount of total ignition timing it has . . If you fix the max amount of timing, I would try it at 20 degrees btdc . . You may also have o delay the timing by modifying the spring tension on the centrifugal advance if you have one.


SPARK PLUG

Use one that is 1 step colder than stock.


OIL PRESSURE TO TURBO AND OIL PRESSURE GAUGE

The turbo needs oil from the engine but won't need very much . . In your case, it should be around 5 to 10 psi at idle with around 5 more psi per 1000 rpm, so at 5000 rpm it should have around 30 to 35 . . Too much pressure will blow past the seal.

You can put a pressure gauge in the oil line before the turbo and regulate pressure by inserting a restriction in the line before the turbo like a main jet.


BLOW OFF VALVE

This are needed to these are not needed on turbos that use the carburetor before the turbo.


BOOST GAUGE

Get one.


ADJUSTABLE BOOST VALVE

You won't likely have enough boost to need one.


AMOUNT OF BOOST TO EXPECT

Around 5 to 6.


CAMSHAFTS

Most people doing this at home have the wrong camshaft . . If you have a supercharger, you can run pretty much any cam you want and it will run fine but turbos run best with a cam thats specifically designed for them and these have long exhaust durations and vert little overlap.

WHERE TO BUY

This place is the cheapest and ships world wide . . I could probably sell them for around $180.00 to $200.00 each if I had maybe 4 orders.

buy a 250R........save the money.

[briano]

This guy baits you in and you guys don`t even ask what kind of bike he`s gonna turbo charge ? Thats because you blow more than you know !

He wants to turbo a Suzuki 160. It's in the first post. If you read it you would know

[oldskool83]

buy a 250r....no one will buy a turbo alt160

[Jmoozy27]

Turbo on a 160??? Seems like a lot for nothing IMO... How about a turbo quadzilla trike conversion??? That would be worth it...

Hawaiirider, be not deterred in thine mission by the nayasers and "other" who can't read, for blessed are those whom seekest not the easiest way to glory thru abundant horsepower with big bore kits and stroker engines, but instead choose their own path to salvation at the finish line by taking the road less traveled.


IT'S GONNA BLOW

Since a turbo increases power, it obviously puts more stress/load on the piston and rod etc, and my guess is that anything over 5 psi is tempting fate . . A forged piston made from 2618 [low silicon] material is the best piston to get, but then you still have the stock rod and the only real way to find its limit is to keep running more and more boost until it hurls.


CUSTOM CAM

This is the single best power increaser you can get . . If you want a big gain in hp, a custom cam designed specifically for a turbo will help a lot but it's a little pricey, and then you then need better valve springs etc . . you will loose a little bottom end perf with a turbo cam but turbos are all about engine rpm . . Turbos are great for people that like to rev the crap out of their engine.

As I mentioned, in general, the faster the engine spins, the faster the exhaust will exit . . the faster the exhaust exits, the faster the turbo spins, the faster the turbo spins, the more hp and rpm you will have and the more rpm you have the faster the turbo spins and so one.

Web Cams may be able to make you a turbo cam that will work better than the stocker even though you don't have some of the info like head flow.

EXHAUST PIPE SIZE BEFORE AND AFTER TURBO

In addition to exhaust gas speed, you also need volume . . This is a bit of a trial and error area, so in your case, I would make two different pipes from the head to the engine and test them both back to back . . I would make the first one using the stock pipe size and the second one would be 1/8" larger in diameter.

I would make the size of the pipe after the turbo the same or slightly larger than the port on the turbo and at least 10" long . . If you make it a long pipe, I wold make it slightly larger than the port on the turbo . . Excessive back pressure in this pipe will slow the turbo down . . Absolutely no back pressure or no pipe will also likely cost some power . . The exhaust is extremely turbulent as it exits the turbo and a length of pipe will reduce this turbulence which will help it exit the turbo more efficiently and it also removes the turbulence from the turbo impeller ny moving it farther downstream.


TURBO INSTALLATION EXAMPLES

This guy put an IHI RHB32 on a 150 Lifan engine using the draw thru method . . Unfortunately, it doesn't make any boost because it is too big and his engine doesn't rev far enough to spin t fast enough etc.

This guy made a turbo golf cart using a 5.5 hp engine and got 8 psi of boost out of it . . If someone can do that, you can certainly put one on your engine without much trouble . . In the first video it has 5 psi of boost, and in the second it has 8 . . This thing would easily do 60 mph.

buy a 250r

Hawaiirider, this is an xlnt idea, because this way you wont have to worry about getting hurt because the bike has too much horsepower.

....no one will buy a turbo alt160

Unless they are one of the few whom think they are manly enough to handle the massive g forces its uber powerful engine generates.

This whole thread reminds me of a guy back home that owned an AMC Matador with about $100,000 (1980's dollars) worth of mods done to it. Every time I would see it at the car show I'd stand in awe as the word "WHY?" would be flashing through my mind.

[barnett468]

.
Why do people put chrome and polished aluminum parts on their engines since it doesn't make them go any faster?

Why would someone put a polished turbo with hand made custom polished intake manifold with fuel injection on a dart with a 225 ci engine?


.....................


Why did glamy put a chrome rack and chrome or nickel plated exhaust pipe and swingarm on his bike?

I think some things are just best left unknown.

A AMX maybe, but a Matador I say what are you thinking?

Hell yea, a Javelin or a Rebel, go for it, sweet rides, but....


Hey Barnett, will you be bringing one of these to the Barrett Jackson auction?

Hey Barnett, will you be bringing one of these to the Barrett Jackson auction?

Somehow I just don't think their clientele would be sophisticated enough to sufficiently appreciate the elegant stylings and understated performance traits of that particular model and are more likely to be interested in one of these.

I recently installed a turbo on my atc 70 with an Ecotrons efi kit. I had no problem getting 9 psi in 1st gear but as soon as I shifted it dropped off to 2-3 psi. Even at 9psi the engine seemed choked compared to it running n/a. It's a lot more complex than just slapping a turbo on. It can be done but I have given up on mine for now.

[hawaiirider]

the whole deal with me wanting to turbo it is have a sleeper, looks like a small Suzuki trike but really rips up big dunes. it seems within $ limits using the ecotrons kit and ill have the time to mess with it soon, haven't even got this alt 160 fully built yet...
a nos boost was turned down as was running alcohol.
I got 196cc out of the 160 motor (essentialy a alt125 motor) so its maxxed.
I bought a suxuki 230 camshaft and they are identical unfortunetly... wont help

I know with enough tinkering the turbo will work, unless I go back to the alcohol or nitrous setups
ive had a few 250r's im a Suzuki guy now and only need a fast bike when I hillshoot in the dunes, most of the time im pulling kids around in a trailer or trailriding

[DohcBikes]

All anyone ever posts is half done turbo projects. There's a reason for that.

Easy enough to mount em up for pics though.
