Heavy duty timing chain

[Steve]

So I am basically starting small and using this a learning curve with tuning, fitment, fuel, oil, etc. then I plan to swap out for a bigger turbo if necessary.

My opinion? Wrong direction.

Smaller engine needs a smaller turbo.

As I said, it will take one of the racers on the board to get you specific numbers, but I think the turbo is too big.

The feed back I got OSS was that it was to small....LOL!
Either way the turbo is a ways off I have a ton of other stuff to do, swing-arm,front end,frame gussets, engine inspection (seals, gaskets and what not), install the 1100 in the 750 frame.

I just took some pics of the first early mock up tonight. I am going to start a build thread here real soon. I am calling it the Cafe/fighter/muscle/soon to be turbo bike...LOL!

Please pardon my ignorance, but I don't speak "text".

What is OSS?

Yeah, I have seen "LOL" enough to know what that is, but it is my humble opinion that too many "texting" "words" are finding their way into the real world where full keyboard exist.

About the turbo ... are you sure you heard correctly? Maybe it was said that the bike was too small?

Sorry man I thought most of the people on here knew what OSS (OldSchoolSuzuki.com) was. Here is the thread I posted over there asking about the turbo in question. I agree it may not be the best turbo for the application but it definitely was the best turbo for the price. Free

Thanks for the clarification.

I don't get to some of the other boards often. I have heard of the OSS site, but there was a word missing from your post that might have led me there.
If you had said "... the feed back I got from OSS ...", I might have guessed, but without the "from", I was totally lost.

Good luck with the turbo, but until you make sure that it will, indeed, work with the displacement of your bike, I think it would be an exercise in futility, not creativity. My guess is that your free turbo might not make any boost at all until the engine is spinning up in the 7,000 range, and then might only make a couple pounds. Those couple pounds of boost will only barely make up for the reduced compression ratio and certainly won't put it up in the 180hp range you are hoping for. Then you have to factor in all the weight you will be carrying with virtually no power increase and the need to change your carb jetting (again) when you end up getting a proper turbo, as your jetting will have to change with the additional air flow at higher boost.

Good luck with your project (I saw your pics in your build thread), I just wanted to try to give you a little heads-up on the turbo selection. It's also possible that I am the one that's due for an eye-opening here, too. I have never tried to adapt a turbo from two engines that were so different, but they might be different enough to compensate.

No problem man, I appreciate you constructive opinion. I still have allot of research and learning to do myself. Either way its gonna be interesting!!

Not sure how turbo sizing works on a bike, but for a car if the turbo is too small, it spins up quickly and then is done. It will also tend to glow red at high rpms. If it is too large, it will have lots of lag and not perform as well as expected. Compared to my GT-67, that one is tiny.
Going strictly by displacement, I would expect the turbo from a 1.8 liter engine to be too large for a 1.0 or 1.1 liter engine. However, there are many factors in sizing a turbo; housing style, impeller shape, valve lift and overlap, overall flow characteristics (carbs vs. EFI, head shapes, exhaust flow), rpm range, etc.
Once you get the mounting flange in place and everything working, it is not that difficult to swap turbos out if you need a different one. Also, it appears to use an external wastegate, so you might want to see the Audi guy to see if it is still around. Not sure if a BOV is needed for bikes; for cars autos don't need one but sticks do.
I would expect those that turbo bikes to have the knowledge, so it sounds like you are trying the correct web locations.

You find a LOT of ebay resellers selling APE stuff at above the price you could get if you just bought it from APE.

You noticed that. Why so many people think stuff is cheaper if they get it off of e-bay is beyond me.

You guys did an awesome job on my machine work, and am very satisfied with the whole experience. I'm an APE booster. You'll have another couple sizeable orders from me in the near future.
