did anyone pick up any mph over stock....???
|
When I put Danas on my 454 Mags, I gained 2 mph & lost 100 lbs. over the stock setup.
I can't say that that gain was all the Danas, I put on some roller rocker arms at the same time. Not that roller rockers would make that much of a difference, but I'm sure it helped a little. |
I have been having the EMI's for 5 years with no problems. I got the long risers, they sound great! You will lose a lot of weight over the stock cast ones
|
I wouldn’t, there are a lot of other products out there that would last longer and perform better. I have used them and only lasted 10 hours.

I installed (2)sets of Stainless Marine manifolds on my twin 502 MPI's. Nice quality, kit complete, 5 year warranty, and dry joint design. Brownie provided good support @Stainless Marine on any questions. it was nice clean install with all correct brackets included for the MPI. Cheaper systems on market, but I thought Stainless Marine was the best value. I wouldn't hesitate putting them on another boat.

I have EMI on my merc 502/4 years/ no problems. Lot less weight than stock. As far as picking up mph.........not really sure...maybe a few. I'd go with CMI's just because a nice, shiny, full header system looks sweet.

I've had EMI's on my 454 Mag Mpi for 8 years. They are still working and look decent. I saved 64 lbs and picked up about 2 mph. I played around with an adjustable fuel pressure regulator and ended up using the stock pressure setting for best performance.
