tristanlee85 Posted September 5, 2008 Report Share Posted September 5, 2008 1300cc is calculated and I'm not sure exactly what the closest size they come in is. I'm hitting 90% - 95% on my 900cc's and timing is still in the teens. I think the next common size about 1000cc is around 1260cc. I am also looking for a wastegate spring for a 38mm Tial that is around 18psi, 16psi at the lowest. On top of that, I have a set of (4) 900cc's low impedance to sell if anyone is interested. These were originally purchased from Racetronix and flow-matched to 1%. They have seen about 500miles of E10 an 6000 miles of E85. Link to comment Share on other sites More sharing options...
tristanlee85 Posted September 7, 2008 Author Report Share Posted September 7, 2008 I got the injectors now. Anyone with a spring? Link to comment Share on other sites More sharing options...
coltboostin Posted September 8, 2008 Report Share Posted September 8, 2008 Just for clarification, you making over 600whp? Otherwise, you should not be outflowing those 900's. Link to comment Share on other sites More sharing options...

coltboostin Posted September 8, 2008 Report Share Posted September 8, 2008 He mentioned e85 ? It would still be good for 500+whp on E, but it does make a difference. Link to comment Share on other sites More sharing options...
Guest Removed Posted September 8, 2008 Report Share Posted September 8, 2008 Just for clarification, you making over 600whp? Otherwise, you should not be outflowing those 900's. me thinks not enough fuel flow ie volume from the pump Link to comment Share on other sites More sharing options...
TurboTank Posted September 8, 2008 Report Share Posted September 8, 2008 with 4 bar fuel pressure? Link to comment Share on other sites More sharing options...
coltboostin Posted September 8, 2008 Report Share Posted September 8, 2008 me thinks not enough fuel flow ie volume from the pump Thats the bush I am beating around. with 4 bar fuel pressure? Pressure Vs. Flow boss. Google it. Link to comment Share on other sites More sharing options...
tristanlee85 Posted September 8, 2008 Author Report Share Posted September 8, 2008 Fuel pressure and flow from the pump is sufficient. I am running a Walbro 255. 400bhp at .65 BSFC running E10 gasoline with a max duty cycle of 80% will require 850cc injectors. Those same specs with E85 will require 1291cc injectors.

Then do explained how I tuned a 2.0l car on E to 621whp with just 1600cc injectors. Maybe its my PR magic? Link to comment Share on other sites More sharing options...
tristanlee85 Posted September 8, 2008 Author Report Share Posted September 8, 2008 I don't know. I didn't tune it. Regardless, I've got the injectors I need. Just still looking for a spring. Link to comment Share on other sites More sharing options...
Guest Removed Posted September 8, 2008 Report Share Posted September 8, 2008 with 4 bar fuel pressure? 1 bar is what 14 psi...pressure means nothing without volume. you can make pressure all day, dont mean theres volume behind it. Link to comment Share on other sites More sharing options...
