10 psi on stock motor

[URPREY]

(05chris @ Apr. 10 2007,18:45) i just watched a ghetto kit get dynoed at motorheads, stock compression, it made 294hp on 110 with a full pipe, and s2000 injectors. it's all in the tune and whos tuning it

I sort of agree on the tuning part, but there is a point where you know you're in jeopardy of blowing something. Anyway, having a turbo is a blast for sure!

(fstbusa @ Apr. 10 2007,19:10) yeah but he had s2000s.  We are talking stock injectors.... stock injectors are pretty maxed at around 7-8 psi.  I even get an overduty cycle error at times when running at the strip with 7 psi.

yea but common how hard is it to find a set of s2000 injectors and put them in? it anything just for piece of mind

 

[fstbusa]

yeah but I have heard its a little difficult to tune s2000s off boost since they deliver so much more fuel.

I haven't seen a bike with s2000s yet... I agree though... the injectors are found everywhere and usually people are snatching them up left and right.

What about tuning off boost using CBR1100 xx injectors? I hear they fall in between the Busa and S2000 in flow rate.

I checked out a few on ebay, and noticed 550cc and 750cc were available, how many cc is a stock busa injector? couldn't find that in the manual. I'm guessing the 550cc's are the ones we would use, and I wonder what that map would look like

I wouldnt go no more than 8lbs.

I have the following setup running @7psi

s2000 injector 1:1 fuel pressure regulator, 255l walboro pump, power commander, plus Pcom hub with 3 bar map sensor. My map is all negative values to get it to run ok off boost. with boost it runs nice.

Bike runs an A/F between 11.8-12. On my dynojet dyno it showed 249hp and 138ft/lbs I still need to do some tuning but I currently have no time.

Bike ran 8.83 last weekend with 230lbs rider I will need to change the gearing to 16-41 to get it to leave the line quicker.

I think both of those are way bigger than S2000 injectors.

My ghetto stage 2 has 550 secondary injectors in addition to stock. I am not sure what the stock is specifically...

I agree; I doubt hte S2000 injectors are 550s...
