my 85 p type?

 

[Supra Bob]

182 cc's per minute.

And before you ask, the largest the stock ECU can handle without needing to mess with the AFM or adding on a piggyback fuel computer is 210's, tho the gains of larger injectors on an N/A motor have been debated for mild to moderately modded motors..

 

[Avp23]

same thing

then do you know what size the 7mgte is and a 7mge injectors are?

 

[Supra Bob]

7M-GE from 87 and 88 had low impedance 295 cc injectors... 89 and up had high impedance 315's
7M-GTE's have 440's.

 

[Avp23]

are you sure about 440's. my friend who owns a 91 said 325 sounds more right? or maybe your right?

 

[Supra Bob]

Yeah, I am sure... 325's are RC Engineering's upgraded version of the 295 N/A injectors.

Units of measurement for injectors

I was looking at the Granatelli web site for the MAF conversion and they list a number of different calibrations for the Ford MAF's. But, they're all in pounds. Any idea how we get from the 182, 295, 325, 440, and 550 we use to pounds? :?

Thanks,

 

[Supra Bob]

Multiply the pounds per hour of the injector by 10.5. That converts it to cc/min.

Ex: 20#/hr.*10.5= 210cc/min

Injector sizing - thanks, Bob

Thanks, Bob,

Now I just have to decide what I'm buying next... :wink:
