Default injector questions

im hearing tons and tons of goodthings about the new bosch thousands and had a couple questions for tuners/users of this product
would these b overkill for a setup that makes 300wh and another that makes arund 4-450..
i know very little about this kinda of thing...i only know that i will not spend 500bucks on rc injectors when the bosches are around 150.

The Injector Dynamics Bosch injectors are not the cheapest, but they are the best. We have 750's available now as well for those that don't need 1000's.

j/c are the 750's the same as the 1000's in terms of being able to run higher base fuel pressures?

i found the bosches for $115....
but ther 1000cc....would these throw of idle or duty cycle for running such low power such as 300-400whp?

The new bosch 1000cc's are saturated injectors that is why they work so well for keeping a like stock driveability and idle because OEM honda ecu's have saturated injector drivers built into them.

The standard 1000cc injectors were generally peak&hold style which require a minimum of a resistor box to make them work but thats where you get the misfire idle and poor drivability. To correct this with a peak&hold injector you will need to run a peak&hold injector driver like those offered by aem and fjo or run an aftermarket ecu that has one built in which usually mean big bucks

If tony is offering them in a 750cc then im sure they are the same modified injector that is used for the 1000cc just not as large and will idle like stock and be a saturated injector which means they should work fine with high fuel pressures. BUT if your going to run a 750 at a really high base pressure then unless you already own them just get 1000cc's and run lower base pressure. its much better for the fuel pump anyway

awsome thanks for the info..the reason i ask is that ive run out of room with my 440s...ive hear so many good things about the drivabilty with these wich is a big concern for me...
so id be fine with a 1000cc bosch saturated without a res box?
i already have a resistor box wired in as is so should i just go with unsaturated?

No get rid of the resistor box and wire all of it back to the deadend plug and run the bosch's. Either that or get a peak&hold driver which run about 150 bucks plus the cost of new injectors or IMO just get the Bosch's

The Bosch's are $115 each, not for a set.

The 750's have the same high pressure capability. I will have definite data tonight, but so far it looks like about 1150cc/min at 100psi.
