Jamesy Posted May 10, 2011 Author Share Posted May 10, 2011 Thanx guys. Lee said the fuel system will be good for a grand hp Its a BiG expense i didnt need but its essential for the good of the car/engine so its a no brainer!! Link to comment Share on other sites More sharing options...
hodge Posted May 11, 2011 Share Posted May 11, 2011 You going with a -8 feed split to 2 x -6 for rail and a -6 return. Or going mental and using -10 Link to comment Share on other sites More sharing options...
Ricky49 Posted May 11, 2011 Share Posted May 11, 2011 Good move Jamesy. I think we need to get onto Lee about a bit of discount. Both of us for some ID 2000 and twin Bosch You for the fuel system Link to comment Share on other sites More sharing options...

U should grab some tho for your future plans Link to comment Share on other sites More sharing options...
Wez Posted May 11, 2011 Share Posted May 11, 2011 You could just up the base pressure, if you look at the Bosch 044 graphs it's at higher pressure they really flow well and you already have an FPR so should be a piece of cake, you would just need to check that your injectors are ok at higher pressure but you prob don't need to go mad to give you enough fuel anyway.

Jamesy Posted May 11, 2011 Author Share Posted May 11, 2011 My FPR is already wound right up mate. Plus injectors are absolutely maxed. At least with bigger injectors, bigger lines and another 044 we'll have loads of headroom and can wind down the fuel pressure Link to comment Share on other sites More sharing options...

Jamesy Posted May 11, 2011 Author Share Posted May 11, 2011 Not sure now mate will need to chk with Ryan but after new fuel setup we'll prob set it to stock Link to comment Share on other sites More sharing options...
Wez Posted May 11, 2011 Share Posted May 11, 2011 Here is a nice graph showing flow rates. Link to comment Share on other sites More sharing options...
Jamesy Posted May 11, 2011 Author Share Posted May 11, 2011 nice1 Think im gonna go with the new whifbitz fuel rail. Unsure on injectors might go for a set of prescion 1600's Link to comment Share on other sites More sharing options...

Wez, by increasing the base pressure what does it allow you to do, can you please elaborate? Can one stay with the same injectors & fuel rail (despite the injectors being maxed out).

Can one stay with the same injectors & fuel rail (despite the injectors being maxed out). Injector being maxed out is not the right term, its only maxed out at that given pressure. Injectors work by open and closing for given time period, if you increase the pressure for the same given time more fuel is injected, there are other things to take into consideration, the injectors will be rated to a maximum pressure, beyond this and you may affect the spray patterns or worse cause the injector to lock. EDIT: just to add to this, the bosch injectors are rated to fairly high pressures, from memory much beyond what we push them too as are the 044 pumps Link to comment Share on other sites More sharing options...

Jamesy Posted May 11, 2011 Author Share Posted May 11, 2011 Yeah Ja just checked they are low imp so no good!! Will keep looking def using pauls rail though looks quality Link to comment Share on other sites More sharing options...

I would of been happy to explore how far i could push mine but with mapping after every change would get expensive!! Link to comment Share on other sites More sharing options...
Wez Posted May 11, 2011 Share Posted May 11, 2011 Yeah Ja just checked they are low imp so no good!! Here are some injectors with roughly same cc in high impedance http://www.fuelinjectorclinic.com/cgi-local/commerce.cgi?preadd=action&key=IS245-1680H Link to comment Share on other sites More sharing options...
Wez Posted May 11, 2011 Share Posted May 11, 2011 These are what I have but not got round to installing them or the new rail yet http://www.fuelinjectorclinic.com/cgi-local/commerce.cgi?preadd=action&key=IS145-0900H Link to comment Share on other sites More sharing options...
suprab Posted May 11, 2011 Share Posted May 11, 2011 are 800cc injectors the biggest "drop in" you can get?? after that its rail etc? Link to comment Share on other sites More sharing options...
Luxluc Posted May 11, 2011 Share Posted May 11, 2011 Nice move Jamesy. I went for a complete fuel kit (PHR kit) when I went single .. and never regretted it since then. The kit went through my 3 single setups, and the only thing I needed to change was the injectors, as I needed some bigger ones at a certain moment.

johnny g Posted May 11, 2011 Share Posted May 11, 2011 Jamesy, I know you said that ID2000's are too big for your needs, but think about where you see the car in 2-3 years - some future proofing would be a good plan here! Link to comment Share on other sites More sharing options...

How about MOT emission test? I guess with very big injectors, your CO values will be quite high at idle, isn't it??? Link to comment Share on other sites More sharing options...
