Performance Upgrades

To my eternal chagrin, I didn't appreciate Kevin and his wisdom when I began riding, and reading Petersen's Cycle magazine.
But, *most* 14-year olds are stupid, anyway. I am responsible for single-handedly creating an entirely new level of stupidity when I was 14.
 
There are a lot of false and misleading videos on youtube. This is just one of many.

I, in my limited understanding of performance tuning, will agree.
And it sounds like you're channeling Kevin Cameron.
Cool.

Perhaps Kevin and other engine tuning stuff I've read about. There's cool website called engineLabs.com with all kinds of cool techy details about engines.

I want to be as clear as possible for my application so not to get everyone trying to talk about other aspects of the bike.

I look at Ducati and Aprilia v4 motorcycles as well as others with more powerful engines. The goldwing is able to put out up to 300hp with a turbo and minor mods without changing the internals in it. Other bikes like a BMW k1200rs can do the same.

If the st1300 was designed for uta maximum HP and torque, it would be the first from Honda.

I have an opel gt that is a 87hp 110ft/lbs torque 2000lbs car. With a different drivetrain and other mods to lighten it, it will be closer to 1500-1600lbs. Many legend race cars use the CBR, r1, and originally the fj1200 that made them fast and fun to drive.

I can get an RSV4 motor that has plenty of power stock from the engine but would be very expensive to maintain and hard to modify for a turbo. Everyone is thinking why not go for a Hayabusa? Yes I can but the v4 has much more low end torque and with a turbo or supercharger, I believe it would give me the acceleration I want more then HP that I cant use as a daily driver on public roads.

I want the fuel economy of a small engine in a light car when I'm taking it easy. I also want HP and torque if I ever decide to take in drifting or racing a big brother Corvette once or twice, but probably not.

I believe the Honda motor has the potential like other Honda motors in motorcycles and in cars. They have always been overbuilt with the ability to double and sometimes triple the power before emissions gets through with them.

If anyone agrees and can give me some advice or point me to anything that will help me modify the ENGINE for better performance in a car swap, I'd really appreciate it.

Thanks

I think your on the wrong site
 
Blah blah, blah blah blah, blah blah, troll blah blah blah blah blah.........trolling....blah blah blah ba blah
 
No need to apologize, it's just that there are very few here who have tried to make this V4 into a higher- performing engine. And even fewer who have successfully done so.

The last attempt was someone wishing to change the gearing in the final drive. Haven't heard how that went, but I recall he appeared frustrated that there wasn't much help.

Many of us find the engine pretty much ideal for our purposes, although I would like a 6th gear. I won't get it, though, and that's ok.

Sometimes the juice isn't worth the squeeze.

Good luck.

Go to opelgt.com. Stick with a 2.4 liter engine and get a getrag 5 spd.. That will be easier than another type of engine....
 
It is kind of hard to accurately measure the engine while it is in the bike. That said, you might PM @Uncle Phil . He is currently on a big loop around the western states, but he did swap an 1100 engine into one of his many bikes not long ago. The extracted one is probably sitting on the floor of his garage. I have no idea how anyone would know the internal parts ratings unless they were heavily into performance increases, and as said already, almost nobody on this website seems to have that interest (at least they have not posted threads describing such). In fact, I've only read a very few threads describing forays into the internals of the engine, and these usually involve pulling the heads and nothing else. You might also PM @Igofar and @aniwack, our most knowledgeable mechanics of these bikes.

Hover your cursor over the blued names, click on 'start conversation' and type away. Good Luck. You might also report back here if you do this project.

You could also try to contact Allen Millyard. If you don't recognize the name, do a search on youtube and google. He can probably answer most of your questions.
 
My Auto instructer , said it so simply. To increase HP you most increase all four of Suck,Squeeze, Bang, and blow. Which brings me to a point that has bugged me for years the myth about back pressure "needed" on the exhaust side. Less the back pressure the better, what an engine needs is timing the pressure wave to bouce back to help pull out the burnt air and fuel from the Cylinder.
Opelgt22 ,Myself I would go with a Aluminum block 4 cylinder car engine. Installing a St engine will be expensive in machining cost due to location of the output shaft, bottom right side of the engine/transmission case. Oh yeah ,use a engine that comes from a rear wheel drive car.

I've changed my mind. I'm going to see if I can find a cheap st motor that I can push more and more fuel and air into it with a ms3 ECU so I can keep returning it until it blows up. I'm betting it will do a lot better then people think. Just like how people said these same things about the goldwings that can actually hit close to 10,000 rpm and put out triple the stock power on stock internals.

I'll take videos so place your bets! If it it's able to perform the way I want for my car application, then unfortunately I won't find it's breaking point, but based on everyone's advice I'll make sure I'm a safe distance away when testing.

It will most likely take a month to do, so bear with me. While you make your predictions on here, lol

I have a free engine if you want to pick it up. Has a bad alternator and no ECM. 175k miles. It was an iron butt bike this the high miles.
 
I believe Uncle Phil donated the blown motor to the recycle system.

Several motors are available on Ebay. Most don't have carbs, if that matters. If so, you'll have pick up a set while you're there.

There are few remaining stock parts left from Honda,. The only after market performance parts I know of were after market pipes that were lighter.

Some of the guys tried to "hot rod" the 1100 couldn't get much if anything out of it. You'll probably need to have cams made.
