Matt Harwood Posted January 15, 2005 Share Posted January 15, 2005 Does anyone on here know anything obout tuning diesel engines? One of the guys here at work owns a big Yank pick-up truck. Ford F250 7.3 turbo diesel. He's already installed a load of Banks power products and it's torque level is guestimated at 650 lbft. But He's just bought a 'Banks Six-Gun Diesel tuner' that is supposed to be able to increase power by up to 160 lbft simply by increasing fuel pressure.... (no increase in boost) Does that make sense? - I'm just trying to get my head around how it works... Quote Link to comment Share on other sites More sharing options...
Miguel Posted January 15, 2005 Share Posted January 15, 2005 This page will give you an Idea. Diesels are set to a OEM fuel pressure to give Reliability as well as economy. As there is no Ignition ( it's CI) the only way to up power is either boost (if turbo'd) or Up the fuel pressure to gain more burn hence more power. The other way to gain/move the power about is to play with injector timming ( bit like IGN timing on a petrol).. All is explained here: http://www.bankspower.com/Tech_SixGun_Cummins.cfm Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted January 15, 2005 Author Share Posted January 15, 2005 Smart arse! http://instagiber.net/smiliesdotcom/contrib/tweetz/moon.gif I tried searching the Banks website, but I only looked under Ian's truck info... Certainly works! - It's a tad scarey hurtling down the road in a giant Tonka toy that weighs the best part of 3 tonnes! Quote Link to comment Share on other sites More sharing options...
dandan Posted January 16, 2005 Share Posted January 16, 2005 That motor is a V10 isn't it? A friend of mine has one in a slightly older F250 and I love it. Bit big for this country but well at home bullying people on the freeway. Any chance of a pic Matt? Quote Link to comment Share on other sites More sharing options...
Ian C Posted January 18, 2005 Share Posted January 18, 2005 Is that that crazy black beast I saw last year round Sextons, Matt? -Ian Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted January 18, 2005 Author Share Posted January 18, 2005 Yep, that's the one... It's actually only (only!) a V8, but it can now out-run an F250 with a petrol powered, supercharged V10!!!! I'll get some pictures of it. I now know that increasing the fuel pressure on a deisel engine CERTAINLY makes more power/torque. Seems to be, the more the engine's under load, the more power it creates. 3rd and 4th gear are now awesome! Quote Link to comment Share on other sites More sharing options...
Miguel Posted January 18, 2005 Share Posted January 18, 2005 Ain't diesels Great. VW have been racing Turbo Diesels for years now and with good results. Diesels can produce masses of power at low rpm but are frowned apon for racing by the public as not cool. Only prob is because of the very high compresion you have to be carefull when ramping the fuel pressure or boost up as the EGT's goes through the roof never mind CR . They best Bit is that they will burn all the fuel you can throw at them (To a fashion) as they have no ignition to worry about. Rambling again Heres a pic of Ians truck till you get one Matt.

Matt Harwood Posted January 18, 2005 Author Share Posted January 18, 2005 His EGT's are still less than 900!!!! - The guidelines he got with that fuel thing state that EGT's are fine up to 1050! His seem to peek at about 880 in 4th Quote Link to comment Share on other sites More sharing options...

His seem to peek at about 880 in 4th Don't forget that Banks Quote in Farenheit and the six gun reads in Farenheit so that would be 565c (1050F) max and he is running at 471c(880F) at the momment ! Just a useless fact for ya Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted January 19, 2005 Author Share Posted January 19, 2005 Now that you mention it, I do remember Ian saying something like that, except without the conversion figures... They don't run very hot in comparison to petrol engines then do they... Quote Link to comment Share on other sites More sharing options...

Only problems with raising fuel pressure is particulate emissions (smoke), apparently. I am quite tempted by a modern diesel road car with a bit of tweaking actually....

Zed Posted January 21, 2005 Share Posted January 21, 2005 Matt, who cares about single figure fuel economy, especially when you can get 100 litres for less than £40. It's even dyed a fancy red color !! Quote Link to comment Share on other sites More sharing options...

The unit Ian has on his truck can increase fuel pressure by 25% on it's highest setting. It does smoke on this setting, but nothing too offensive. Similar to an old Sierra Diesel!

tDR Posted January 24, 2005 Share Posted January 24, 2005 Totally OT car wise but I'm having thoughts of tinkering with my TD commuter hack - a '97 Pug 406 1.9Tdi... How can I reliably get more power without impacting on fuel economy? Cheers, Brian. Quote Link to comment Share on other sites More sharing options...
