OMG , it`s a big difference..Pretty much starts to pay for itself immediately .
Yes still throttle body after the quick fuel carbs and now the whipples have 10 injectors in the throttle body in the back.






Sorry to derail but we all know the OP needs a new carb.

Holley EFI has come a looooong way and once set up correctly pretty awesome.

its great that all you guys want to put EFI on 1000hp blower motors. your motors, build them your way. however what does that have to do with my question on tuning assistance and air bleed guide and validation? I dont have a 1000hp motor, I dont have a blower and I have a carb

your posting just to post at this point.

Sorry for getting off topic, and good luck with your carb, let us know what you find that remedies the situation!
other than the EFI talk I think there have been some good suggestions thrown out there. Carry on.

oh sorry , back to fixing your 25 year old butchered up $hitshow carb.
So sorry to answer questions about EFI. How dare I.

you’re just running the injectors behind the throttle body? Might want to dyno with individual egts and see if your manifold would benefit from port injection.

sb is right. The only thing wrong here is cobbled together mismatched parts. Same thing would happen if you pulled sensor out of the scrap yard and pieced together a mega squirt efi.

Yes behind TB ....
No dyno , no need, plus I`m not pulling motors out a 3rd time this year .. the drive guardians wore my ass out pulling motors.
The whipple port injected intake is crazy money. I haven`t found any other intake to work for under $3k so port injection is not on the table.

closing the loop on this

order from Summit finally showed up on Friday. removed all the speedmaster/PCE jets

starting with the IFR, changing from the .0225" to .033"
changed the VPCR's from the .0225 to .059
changed the e-jets from all .0225" to
E1 - .035
E2 - blocked
E3 - .033"
E4 - blocked
Ef - .031"

HSAB's at .032
LSAB's at .059

bolted the carb on, and after priming the fuel system, turned the key and it was idling at 800 RPM

adjusted the 4 corners, and it will idle down to about 700. ended up going to .061" on the LSAB's just to lean out a bit more

now, to drop it in the water to load it
