Just an easy quick question guys.

Are 800cc DW injectors a good size for my 500-550whp TT build?

I think the 600cc may be a touch small for 550whp but im not sure?

Also does any one know how osiris will cope running the 800cc injectors?

thanks.

 

Can't speak on the Osiris, but my DW800's got me to 543whp on a DD dyno. My duty cycle is just about maxed out there on 93oct + meth.

Hope that helps.

 

DW800 should be ok for 500-550 like Cass said.

I know stylinz made 593rwhp on 850's (on 93 octane).

I dunno how big osiris will handle. Are DW800 low impedence or high impedence?

Osiris can handle 800cc, it handles my 750cc fine with twin pump. You will not have a good hot start any longer.... That is all

 

I'm maxing out duty cycle (less than/=95%) making 505 rwhp on DW600cc with 60 psi fuel pump pressure and avg AFR = 11.7 while in boost. My injectors test flowed between 612 cc to 615cc @ 43.5 psi (according to DW). So to answer your question DW600cc injectors are good for the max of appx. 500 rwhp (and not for long period of time) if you turn your fuel pressure up IMO.

 

Thanks guys thats what i thought. 800cc are better suited to my goals. Im tuning the car on a dynapack hub dyno so if you got 543whp on DD then i should get 550RHHP on the dynapack with the 800cc no probs.
