Manifold for my R6
 

Got it welded and sandblasted. Now I have to order some BHK Black Satin to coat it with. Luckily my gf's father has a dual stage airbrush & paint booth O0 In the meantime I am porting & polishing it.

r6 as in yamaha? if so your ------- crazy, but that is gonna be badass. i seen a vid of a turbo r1, nothing but sky lol.

Re: Manifold for my R6
 

Yes, it's an '05 Raven Edition Yamaha R6. I'm gonna re-gear it so I won't have that wheelie problem, hopefully. This is a project I have been researching and buying very specific parts for since November. It's all beginning to take shape now and I hope I get it on the road before fall. Next up is the custom fabb'd airbox..... soon.

Re: Manifold for my R6
 

hey i was considering doing this with my bike. but the manifold desing doenst allow me to do much. did you just buy a stock header cut it up. welded it back togeather with a flange like that?

cuase if you did it that way.. it saves me alot of headaches of reinvetning a proper flange.

Re: Manifold for my R6
 

Yes, It's the stock end pieces and flanges along with a log style manifold I fabb'd up.

Re: Manifold for my R6
 

i was thinking of using a kkk k03 turbo out of the 1.8t golfs it's basicly the smallest turbo i can find besides the IHI RHB5 VJ11.

the vj11 isn't as common as the k03 where i live at. i found the k03 to be the newest and least abuse used. not only that they are dime a dozen cheap. but the flange you have there looks to be like a small t25. i personally think t25 still to big for a standard 600cc. what type of turbo you planning to use?

also how are you planning on running the oil lines. i guessing your skiping the coolant support. taping the oil filter then the crank case.

what about fuel support. fmu, with a power commander?

i have an old carbed f3 honda. and have really weak float bowls so i can't make a blow through design. and draw through is a way i am not going to do.

so i'm planning on going efi, with custom manifold. im am going single throthle body btw. using mostly honda parts.

how are you going to do it?

Re: Manifold for my R6
 

Get a Small GT turbo from the FOR SALE forum, IMO you'd rather have a ball bearing quick spool than max power on your R6.

Re: Manifold for my R6
 

ive wonderd if a 600cc sportbike might flow better/similar to a larger 1.6l car motor, like if it would spool a smaller t3 or 14b fine maybe, plus it has alot more rev range, i think my bike redlines at 14k , either way ive seen turboed gixxers and they look out of control, like they just cant get the front end down

Re: Manifold for my R6
 

ignore my post if you don't like details of why a small t3 or a 14b won't work.
i will also explain WTF post if a 600 sport bike flows more then 1.6 honda motor.

---------------------------------------------------------------------------------------------------------------------

the small t3 and 14b are way too big for a 600 engine.

lets take your standard 600cc engine. average rev capability for most sport motocycles are lets say 13k.

here is my notes the setup i was going to use:
cubic inches of a 600cc engine is 36.6 btw

---Engine Airflow Requirements---
(CID × RPM) ÷ 3456 = CFM [it's to find out cfm first]

36.6 x 13000 ÷ 3456 = cfm
475800 ÷ 3456 = cfm
cfm = 137.67361

[cfm is calculated for 100% VE volumetric efficiency.]
[must use 85% VE for standard engine]

137.6 x 0.85 = 116.96

also lets say we want to use a standard pressure ratio of 5psi

---Presure Ratio---
@ 5 psi

(5 + 14.7) ÷ 14.7 = 1.34:1 pressure ratio

blah blah blah and alot more math later i found the density ratio

---density ratio ---
1.23

[85% VE for standard engine] X [density ratio] = Actual Inlet CFM

116.96 x 1.23 = 143.86 Actual Inlet CFM

the actual inlet cfm is very close to 10 lb/min = 144.718 cfm.

map of a 14b
http://www.graphics.cornell.edu/~v/c...s/td05-14b.gif

if you draw up a line just where the pressure ratio reaches and you draw a line excatly at 10 lbs a mintue. your well BELOW the island of good efficiency. with these turbochargers producing 5lbs you'll have a crappy uncontrolable powerband. not only that but your boost power band is going only to be found the last 3k rpms in your redline. on top of that, you'll be hitting the crappy side of the effincey of the turbocharger. so it's really even more a bad reason to use these turbochargers.

only way to slove this problem would be to up the boost. but the average sport bike motocycle engine is around 12:1 compression enigne. so we can see it's way to big to actually use. but if you want to blow your engine it's fine by me.

also about your question WTF.

1600cc = 97.63CID

97.63 x 7200 rpm ÷ 3456 = CFM (using D16Z6 stock redline btw)
702936 ÷ 3456 = cfm

203.39 = cfm

203.39 x 0.89 = 172.88

your stock honda engine d16 = 172.88 cfm
your average 600 motocyle = 116.96 cfm

d16 engine > 600cc engine

your answer.

Re: Manifold for my R6
 

btw my notes were for my engine which happen to redline at 13k rpms i don't have the slightest clue what the r6 redlines at. it could be 14.5k for all i know which will give a lil more play but definatly not enough to use a t3 or a 14b. like i said even the t25 is still too big.

here is a link to the maps of the t25 & k03 turbocharger.

http://i15.photobucket.com/albums/a3...t25_nissan.gif

the k03 turbocharger seems to have the most play out of all the turbochargers as it'll have a very wide powerband where a suggest 5 psi pressure ratio is planned to hit. although the down side to this turbo charger you'll falling out of compressor effiency near redline. witch is fine by me seeing as all the production turbo chargers that have come out of cars will result in this but luckly it's within an acceptable range of the turbocharger. as listed it'll be within 57% effiency.

although its effiency range is definatly less the the t25 @ full power. durring it's powerband it's emplored well within the island of effiecenty.

i wouldn't be surprized to see 5psi boost at 6k rpm with the k03 where as 8.5k rpms 5psi with the t25.

http://i15.photobucket.com/albums/a3...r/k03_2072.gif

but like i was saying the t25 is still to too big. turth is even the k03 is still to big.
