Im about to put a side draft 44phh Mikuni carb on my 12a. Anybody heard anything bad about Mikuni? What kinda hp am I going to gain with it?

I had one on a previous car, good throttle response and decent mileage.

Man, crabs itch like all hell, make you a total pariah, and are hard to get rid of.

The only effective solution is to get a razor, some lighter fluid, and a hammer. Shave half your pubes off, then douse the other half with the lighter fluid and set it on fire. Then when the little bastards run out screaming, beat 'em to death with the hammer.

Trying very hard to ignore Jec-31's post. LOL

Anyway, Mikuni 44PHH is a good setup for a stock or mildported 12a. I really liked it also for good acceration over stock and no noticable decrease in MPG as mentioned above if driven sensibly.

I had one on my last engine a 12 street port. I do not have the dyno chart any more but I was a 178 hp. the mukini had the larger 2.0 valve . the engine had the larger street port and a old set of re headers ,racing beat dual exhust set up and upgrade mallory fuel set up. It needed to have the fuel pressure kept at 5.2 lbs or it would not run right. oh the mukini intake was mach ported to the engine also. when I kept my foot out of it I got abot 18 mpg

so I need to put a different fuel pump and regulator? The stock pump won't do?

I've got a Holley blue f/p to push gas to my Mikuni. I keep the pressure about 4.5psi and it runs pretty good. The stock pump can't keep up with the carb at higher rpms, it gets starved of fuel.

...What you get for letting your Mikuni play with a Holley.

riffraff

would a 44phh be to small for a stock port 13b?

I have a Mikuni on my 13B street port....
