Bridgey TII HP
 

Hey guys!

So about how much power do you think a bridged TII S4 would make with a BNR hybrid turbo? And what kind of ecu would work? I know sprint re's are popular, would that work? All of this is hypothetical as we're building a car for road racing and have plenty of time and options, just wanting to learn some more

Thanks a bunch!

turbo rotarys have made 700hp on stock ports, if my goal was beyond 700 i would go with a semi PP setup over a bridge, which is good for 800-900- 1100hp(drag setup) for a nice road racing car, i would go with a gt35 sized turbo or a seq twin setup with nothing more then a street port, aiming for around 500-550 max, but good spool.

why does everyone want a giant port and a teeny turbo? you're better off running a more balanced combination, and in fact the stock porting is really very optimal for a turbo, Mazda just used a teeny turbo

So the extra eyebrow would really boost performance by that much vs a large streetport? I'm basically asking out of curiousity as I don't think we'd need or could afford to run too much power, but we're looking for the least amount of lag. We thought about N/A but at this point it's more economical to just run our turbo engine so what would be a good setup for least lag? Power isn't too much of a concern.

I've read online here (stressing ONLINE) that for some reason people see faster spool with a BP but like I said, just what I've heard. Any truth to that?
