İt's Dyno Time, guess whp numbers Options

[tufy]

i finish 2000km yesterday.. it took 20 days. 2000 km is 3 times tour all round cyprus island
now car is at my engineer for a sevice and check up. and wendsday is the tunning day. cant wait results.
as you know our target is 500 whp. what do you think it will be?

Do you have 4 800 cc injectors or are you running 8? If 4, I predict you will be fuel limited and will not get to 500whp.

i have four 850 cc sard injectors with 255 lph sard fuel pump. my tuner said its ok. but if its not we will use 1000cc injectors.

I also think 800cc will not be sufficient. Stock 540cc injectors are sufficient to about 340 bhp. You want 500whp so thats about 600-650bhp. Almost double. So i think 1000cc injectors are the best way to go.

Just did a quick math calculation.
For 675bhp u need 3.480cc/min. devided by 4 injectors you need 870cc/min injectors. So its gonna be close.

It doesn't work that way. You need progressively more injector the higher up you go. Some of the MR2 guys have had problems reaching 450whp on 850's and thats running only two wheels!
