turbo time....

naked fun, as of now i have a 1105 kit on stock sleaves but if i can find something in time to swap it out i will. my turbo is a t25 internally wastegated garret with carbon seals installed.

if i could swap and barter and buy a sleaved cyl up to 1200 id get that to keep, im using a j head that will drop compression. what turbo do you have ?

also thanks for that awesome completely irrelevant post as usual donthavakawman

It is an HX25, non-wastegated. It was one I built for a project that never got off the ground. I fear if I keep the turbo, I am afraid I'll use it on my KZ project!! :woohoo:

But then I am going to have to do a blow through system because it is freakin' cool.....and that will take more time to finish the bike......and I'll end up probable killing myself in the process...

I finished running your breathing lines. The one variable I put in had to be fudged, because without testing, I can't be precise. I gave you a system (Think head ports, intake system, dynamic compression, etc...) volumetric efficiency of 70%. This is based on a number of engines I have done that were spark ignited. You have a very short runner, and figuring you will use a later J head, I think the best you would do on the combo would be 77%. With that being said, and using a ambient temp of 76 F and at sea level (14.7 PSIA) the breathing lines layout with these point of running RPM.

1800rpm = 1.834 lbs/min or 24 cfm (corrected for the above factors)
3000rpm = 3.057 lbs/min or 41 cfm
4200rpm = 4.279 lbs/min or 58 cfm
5500rpm = 5.604 lbs/min or 76 cfm
6500rpm = 6.623 lbs/min or 89 cfm
7500rpm = 7.642 lbs/min or 103 cfm
8500rpm = 8.661 lbs/min or 117 cfm
9500rpm = 9.679 lbs/min or 131 cfm
10500rpm = 10.698 lbs/min or 145 cfm

I selected some of these rpm points as they may be common operating points. Holset uses Holset Flow Parameter, but I provided it in CFM as the majority of aftermarket turbos commonly provide compressor maps in that format.

As I said earlier, No disrespect intended! But, you leave an open ended comment, You will get it used against you around here and it will all be in fun!

Lush is going to kick some asses for muckin up his thread with all this jiberish.....turbo talk only please :ohmy: :ohmy: :woohoo: :woohoo: :woohoo: :woohoo:

What you need is a GPz750. Then add a front mounted turbo, fuel injection, upgrade the engine internals....no, wait....Kawasaki already did that :laugh:

a while back on www.therangerstation.com/tech_library/Turbos.html I pondered upon a saying. I can't remember where it was this saying that I found was, but it was funny I remember that.
"the harder she blows the faster she goes"
but now all this jibberish and I don't see one finished bit of work. sounds like a bunch of talk to me.


... kawkaw....sakisaki...

Another cleanup needed on thread turbo time please...... :dry:

Im just waiting for a big truck(company name here)to deliver a bunch of stuff in next week or so,then youll see some progress.
Im spending next couple days in the basement working on some pieces Ive already been working on that will make it on to his project
