What did you do to your BG today?? - Part II

[1967cutlass]

I'm going to paint the protege "almond" colored in the next few days. Stay tuned.

[protégébob]

guess i never realized that mikes fuel rails were dual feed ready.

[Lex]

thanks guys

meh, these should do me just fine for now. what kind of duty cycles were you hitting on your 460cc's??

At 15-16psi and redline you're into the 90s.

My 550s should be coming in the mail this week.

yeah they are dual feed ready, and i was going to go with a dual feed setup... but from what i read in many different places it is fairly useless unless you are running a LOT more horsepower than i'm shooting for. also you would then need dual lines and dual pumps for it to even be truely worthwhile.

wow i didnt think the 460's would max out that fast! i guess that injectors will be my next upgrade once this thing is running and tuned.

I wouldn't push 460s far past 250-260whp ... and for the dual feed - I have a vishnu rail that is dual feed and I have noticed more "smoothness" but is very subtle. I just feel safer knowing I have a large rail with no surge tank in the gas tank.

tinted..............

[Turpro]

hurry jon. times running out. Looks like some great progress though.


tint looks good. time for rims.

jees ow man!! i've dropped like 3K on this damn thing in the last couple months... short shifter, rims... then it'll be throw a turbo in that bad boy .................................................. .. it never ends!

you don't like my custom hubcaps?

i just want to get my suspension and alarm installed this week and enjoy it for awhile... the suspension and alarm's been sitting in my garage for a couple months... just haven't had time. oh yeah.. finish the stinking body work



i can't wait to finish the body work so that i can buff and wax it. i don't think this car's seen wax in the last 10 years. i gotta finish the bodywork this week so that the paint can sit long enough to be able to wax it before the meet.

No video from the cruise...and no photos either(waiting for the other people who took pics to post them). I locked my camera in the center console of the Miata, and the few times I could have taken video I was driving and couldn't unlock the console. Doh!

But here's a pic of the engine bay.

I wouldn't push 460s far past 250-260whp ...

I still don't figure that. I make 250 on 100cc less. seems fine to me, going on 1.5 years now. Oh well

(sorry if this is a long post ) This has to do with the duty cycle of 460cc injectors. I am running a BPc8 ecu(GTR) N/A RX-7 injectors (460cc) a turbo II RX-7 AFM a VJ-20 turbo. This week I removed my down pipe and installed a 2nd o-2 bung so I could run a wide band 0-2 sensor in my car. I ran it for a couple of days and saw that in full boost up to red line that my air fuel #'s were in the 10's (pretty rich) so I am curious what you have for fuel manangement to have your injectors in the 90% range. If it is the GTR ecu then I can see it because it puts the afr's rich which would explain the maxing out the injectors. I also installed a SAFC after I saw my afr's so I could lean it out some at the top end which should lower the injector duty cycle some. Don't get me wrong, if you are running anything bigger then a vj-20 turbo (no matter what ecu) I would say put some bigger injectors in it (with some sort of fuel controller in it) so you don't lean it out or max your duty cycle, but 460cc injectors should be good for most applications with the right fuel management, up to about 300 hp (which is what the GTR is capable of). If you are running J-spec, e-spec, or a-spec ecu's, you do have to realize that their fuel requirements (92 ocatane, not that every state in the us gets that) don't often meet usa standards, so the ecu's might run a little rich to prevent detonation which would mean higher duty cycles.
Just my 2 cents

Damm my 323 BG miss .
I wait for my sister. She give me her DX92 Rusty Edition huhu

[therieldeal]

jasoncescort, Lex is running a GTR turbo with megasquirt for fuel/spark management.

[Turpro]

fixed the hole in the one tire on the egt wheels so now all 4 are on. might be selling the subi bumper now. idk yet.

(not trying to create any arguments) but with that set up with 460cc injectors "should" be able to get pretty close to that 300hp #. Thats not to say that he wouldn't be close to maxing out injectors I am just going by what I have. With my set up I am not seeing injector duty cycles like you can with a stand alone.
