i've never seen a 6 banger put out 262rwhp... you must tell me ur secrets

 

hahaha

 

I`m not putting anybody down but a specific output of 1.09 hp per c.i.d. is not impressive with 10psi of boost. Is this average? A stock 281 with a rwhp of 265 would be 1.06

EDIT: Fixed your quote - 28HopUp

 

266 with 10 pounds of boost is very low... Get rid of the plasma booster. I've never seen a good word written about them. Get yourself some stock style copper plugs, one heat range colder than stock, and I'd consider even putting most of the ignition as far back to stock as you can and start from there. NExt, I would look at your tune.. What kind of AFR's are you getting?

 

I have got good air fuel ratio they are about the same but I am not sure what exactly what it is. So I should get rid of the Plasma booster?

 

I don't know how the 20's play in but you should be making at least 290+hp at 10psi with full exhaust.

254 is way too low for a supercharged 6.

 

Ok the HO system is suppose to bump you up to 330 @ the crank - 18% losses gives you about 270 to the wheels, -10 loss for the 20s and it comes out to 260ish.....all of these would be on a dynojet....

so adding in the other mods and you on a mustang dyno...anywhere from 250-265 sounds about right actually for a MD

 

That makes sense, but what about the 6s that have the same set up that are getting like 300 to the wheels? I guess most of them are manual and don't have 20's tho and have aluminum ds so I guess that would be right? Right?

 

take the 20s off, be a manual and through it on a dynojet and 300 is probably not out of the question

 

I found the following information on the forums, which may be helpful to you:

I've seen conversion numbers as low as 7%, and as high as 11%, so take the above quote with a grain of salt...
