I posted this over at the drawthru turbo group and i wanted to get your opinions too.
on the one hand i agree that the 32/36( progressive, 320cfm) vs the holley2300 (500cfm). If i go progressive, you can easily attain off boost low rpm manners and economy, and up top whilst it's not huge in total airflow, it would probably still flow more than the inlet arrangement would allow.
I have another question though. i went to a local turbo shop here in
denver. and the owner recommended that i use an SDS fuel injection
system. he brings a valid points about a carb only having 4 or 5
circuits to control air/fuel mixture. whereas EFI can do it all thru
the whole rpm range. i have read some other posts and done other
research(mchinnes and corky bell) i get the feeling that with a carb,
i will be running lean at WOT and that could be a problem.
with this true i WOULD want EFI. however there is a $900-1300.00 cost.
here is the decision point: will i be ok with just a carb?? if i
have a carb custom built for my application. will i spend more or
less than an EFI? will a custom carb have as much performance as
efi?
i didnt get the feel that he was trying to sell me a efi system. but
i do think that his job(of satisfying his customers - Me) is made
easier if i go to the EFI
this is going on a ford 200 cu inch(3.3L), fuel log head, 1.75I, 1.5E
t3/t4 turbo, intercooler, 5500rpm, denver, 10psi boost,
Ben and Dan i especially wnat to know what you think. i knwo there are some out there running efi on the log head and i wanted to know waht you think!!
