motorcycle turbo build....
 

finally finished the turbo build on my 02 gsxr 1000. took it out on the street for the first time and nearly ---- myself. im saving up for a few cosmetic parts but as far as the turbo portion its done. this is my third turbo bike build and i think i am done after this one. a lot of work and money.

Just too ------- lazy to post a link inside some img tags or what?

are you that lazy that you cant click a ------- link????

thanks for the nice introduction to the site.....

Thanks, and yes. Not really that lazy, but unwilling to click something that neither broadens my horizons, or teaches me anything. It's sole purpose to me is for you to show off. So the burden of work is on you!

Kit looks good though, I imagine it'll be loud, but if that doesn't bother you, no harm. I like how you use T-bolt clamps for the charge pipes, but then worm clamps for the intake runners :)

i had the t bolt clamps left over from another build so i just used what i had. there not really required as its a low boost application of only 6 psi. the turbo quites down most of the exhaust noise. you can stand next to it running and chat with someone without yelling.

What turbo did you choose?

Does it over run the turbo in upper RPM ranges, i.e. boost falls off?

its a t25 with the smaller t2 flange. boost is generated at ~8k rpm.

Is it much louder than stock with no exhaust?

its sounds just like you would put an aftermarket canister on a non turbo'd bike. its not too loud at idle.

looks dope man keep up the good work

ooooo nice...I bet thats fast....

I think i've got the same filter on my turbo crx....

fun to ride. right now im working on the fine tune. hoping to get some hp numbers in a few days.

looks good..interested in what it will put down.

just finished up the tuning and it laid down hp better than i expected. ill have the dyno sheet up as soon as i find a scanner.

NOICE!

tried the scanner at work but it came out shitty. ill keep trying. in the meantime.
225hp at 9900 rpm
124 lbs.ft of torque at 9200 rpm

dyno numbers

i want to see video...

i wish i was that far advanced.. :)

Clean work. You said you're only in boost after 8k? So you only have boost for the top 3k?

i wanted to build a street rideable bike. i can ride around town and never boost until i want too. the reason for this is that i left the secondary throttle plates installed to prevent boost until a higher rpm. boost range is around 8000-12.5k rpm. if you look at the dyno graph you can see max power is generated at 9900 rpm so there is no need to go over that rpm range anyway. once it hits that rpm range the bike goes vertical.....

Come on now. Thats the fun part. Torque wheelies. You still using the stock fuel pump?

yes. since i am only using a 1:1 ratio fuel pressure regulator the stock fuel pump can handle it. at 6psi with a 1:1 the fuel pressure climbs to 48psi which the stock pump can handle. the problem with the stock pump is when people use those shitty high rate fmu's that bring the fuel pressure higher than 60psi. i used a 255 and a 190lph pump before and it was a waste of money as it was overkill on a bike.

My bike at idle is 62psi

why?

i can only imagine how a turbo 1000 would pull

its a blast to ride. it pulls hard up to ~ 9000-10000 rpm then the front end comes up.

nice project dude...i love bike turbo projects.....did you buy the exhaust manifold or have someone make it? also when to the secondary butterflies normally open? Good info on the fuel pressure reg. A lot of people normally wind up buying crap they dont need when they do a project like that for the first time.

everything was built by me. i used a 01-03 gsxr 600/750 header and cut it up to get the flanges and bends i needed to make the header. i had to purchase this header because the stock 1000 headers are titanium as where the 600/750 headers are stainless steel.

if memory serves me right the secondary butterflies open at ~6-8k rpm depending on gear. this gives me the lag i wanted. the turbo wont spool up until these secondary throttle plates open. its a great street driveable bike. you can drive around town and never boost until you want too.

as far as the fuel pump goes it will save a turbo bike builder some money. the fuel pump assembly still has to be modified but at least a aftermarket pump wont be needed for low boost.

im really impressed, i want to turbo a bike, eventually but itl have to wait probably till im out of collage. so the fuel is controlled by a FMU 1:1? and this is non intercooled?

is the compression ratio out the roof?!?! how is the throttle plate setup on this bike? bov mounted on the intake mani, soo... ive never been close enough to a bike to figure out... lmao

Sweet bike.

the fuel is controlled by a 1:1 rising rate fuel pressure regulator and a power commander 3r tuned for the bike. dont confuse a fuel pressure regulator and an fmu. all turbo vehicles need to have a 1:1 rising rate fuel pressure regulator. this helps the tuning aspect. it will create minor fuel adjustment tuning cant create. an fuel pressure regualtor replaces the factory fuel pressure regulator because it cant see boost. an fmu is added after the oem fuel pressure regulator and it raises the fuel line pressure ridiculously high. not recommended as it can cause fuel injector damage and fuel line rupture.


compression ratio is stock and i believe it is 12:1.
motorcycles dont have intake manifolds so a plenum has to be made to tie each throttle body together. i mounted the bov on the plenum but it can be mounted on the boost pipes as well.

it is a non intercooled setup as it is less than 8 psi. stock motor can only handle 6 psi so there is no reason for an intercooler for low boost.

This post is almost hard to read, first because your complete lack of spelling/grammar comprehension, and next because of all the ignorance contained within.

Not all turbo vehicles need a 1:1 rising rate FPR. Mine does not have one, and it runs perfect, and holds a perfect AFR through all conditions it's put through. Tuning can't create minor fuel adjustments? You're ------- kidding me?

The factory FPR cannot see boost. Who cares? It's just fuel pressure, and doesn't need to change much from idle. You don't tune with fuel pressure, you tune with pulse widths.

Motorcycles often times do have intake plenums, they are just more of an airbox, and are before the throttle plate. This changes their performance characteristics, but they can see pressure and tie all throttle bodies together. My bike, as with all new sportbikes, are this way.

There is no need for an intercooler because it's low boost? You do realize that turbocharging isn't about need and requirements, and more about preference and desire, correct? I'll make that an accurate statement, there is no need for an intercooler when your power goals are as low as his.

spelling/grammer? is this ------- english class. no asshat, its hmt...


you build your ---- without a boost reference fuel pressure regulator and ill build mine the right way. all factory turbo vehicles have a boost reference fuel pressure regulator. fuel pressure has a direct affect on injector flow so i dont see how you can say who cares. perfect afr? what do you consider perfect afr? show me dyno results to back up your supposed perfect running vehicle based on afr. theres a lot more to tuning than afr.

you want to properly tune with fuel pressure and pulse width. load on an engine is different in each gear and tuning for that difference is very difficult so a boost reference fuel pressure regulator will fill that void. ask any tuner and they will recommend a boost reference fuel pressure regulator. you dont need one but it is recommended.

an airbox is not a plenum. if you built turbo bikes then you would know this already. ive built 4. stock airboxes are plastic and littered with emissions equipment that make it tough to use as a plenum. hell, some airboxes are built into the frame such as the zx12.

sure you can install an intercooler on a vehicle with low boost. i never said you couldnt, i just said there was no need. on a bike theres barely enough room for the turbo let alone an intercooler and to do all the work of an intercooler install on a bike for 6psi or less is a waste of time and money. most stock motorcycle engines can only handle up to 6 psi before they blow sky high so intercooling a motorcycle is more for built engines, high boost and big hp numbers.

ok, so an "L" being a little lost in "regualtor" along with "dont" not having a ' == "complete lack of spelling/grammar comprehension"

Am I glad I don't have to deal with this guy every day...

Busa4... you did absolutely awesome,
There is absolutely nothing wrong with your power figures.
you are an inspiration to all that can appreciate a well executed install.

Yeah dont i know that one......i have seen a turbo version of my bike and i know it had to be a pain in the ass. You practically have to weld seal the frame and attach intake pressure line connection. I like the design but it seems terrible for turbo'ing.

i had an 03 zx12last year and i wanted to turbo it but i looked at the work involved and said the hell with it. i ended up parting out the bike. if you want a turbo bike stick with a gsxr as there the easiest bike to turbo.

Good work on this build.. It all looks very compact, will it all fit under the fairings? I wanna do one of these but I want the stealth look (at least 'til the BOV farts;D) the exhaust poking out the side is fine. but I'm not keen on half-fairing jobs, you might as well start with a naked IMO
