bosch 440cc injectors instead of 4bar fpr?

[Jay]

Which block are you using to log injector duty?

i don't know any block giving the injectors duty cycle and i don't think there's one (maybe m0rk or someone else know one ) but using block 002 per example with engine speed and injection timing you can have an idea of inj. duty cycle :

"60 * 2 * 1000 / engine speed" gives the time available for an injection in ms

so it would be :

100 * injection timing * engine speed / 120000

i don't think it's quite accurate but i may give a good estimation, here's an exemple on one of my logs :

Can i ask you how much it cost to import the turbo?

Around $2,000 including the manifold and delivery but not the injectors and software.

 

[Olly20VT]

thats a good price because thats dolars, iv been told there are 3 turbos in the range, any idea of the prices and specs of them? or do you have any links to info on them?

Going by your formula and the 002 I did this evening I see a max of 92 at around 6600rpm.

Going by your formula and the 002 I did this evening I see a max of 92 at around 6600rpm.

i've read that it's recommended that injectors duty cycle should not remain above 85-90% for long periods , so if your is only reaching 92% near redline i think it's ok

concerning my ibiza i will go for 4b fpr and stage 2 just to lower the IDC i think 317cc injectors may be another solution (as the 4b fpr seems to give a 15% gain over the stock 280cc injectors) but i'm not sure the remap would be totally ok with it and the 4b fpr is definitely cheaper

My.has a lcr with.green giants.and said theyre the mutts nuts, he also has an unopened pack which re is recommending me to install....ill let you whats goin on
