Summary of change:
Subpage of MembersPage/MarcellGal/PowerAndTraction ---- '''Injector''' Brave men do like this: in audi 5cyl 20vt thmb rule: cc/per injector = max power in hp. 440cc = 440 HP I think it's brave. But with tuned boostcontrol it can be tried. If going up slowly, one will know when running out of injectors flowrate. I think there is an error on http://www.rceng.com/technical.htm they swapped the BSFC for turbo and supercharged. Turbo is better (lower). Below I calculate with BSFC(gasoline)=0.55l / (HP * l), consistent with some other sources. examples * For factory 220 Hp 220 * 0.55 / (5*0.8) * 10.5 = 317cc/min (they used 350cc/min) * Teppo Kalske used to have 460cc with wich I ended up 100% dc at 5000 rpm with reasonable afr (HP or torque known ?). Prolly maxed out near 400 HP: * for 400 HP, even with 100% duty: 400 * 0.55 / (5*1) * 10.5 = 462 cc/min needed ** <Jorgen__> It's recommended but not needed. * or in other words 360 * 0.55 / (5*1) * 10.5 = '''415 cc/min (enough for 360 HP)''' should be good to start with Jorgen's note: If the stock injectors is 350cc the 415cc injectors in the webshop is almost identical in size. (good point!) 350cc/min@3bar is same as 404cc/min@4bar: 350 * sqrt(4/3) = 404.15 Then we can use the stock injectors instead, at 4bar fuel pressure of course. Jorgen will check if he finds a 4bar regulator for me (isn't it just a stiffer spring inside the FPR?). ---- '''Fuel Pump''' Kalske's hints in case we wish to use 044 pump in PnP install inside fuel tank * 895201531A strainer * 895201779H reservoir mount * 90330701 polttoaineputki/banjo * 0138128 2kpl tiivisterengas * 0110691 kupumutteri First two are the most important ones What is the hard part without these ? I think Nanassy and Karkus will probably handle this, but I really don't know about the potential complications.
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
