bigger the port, the faster the motor spools the turbo. also the bigger the port, the less low end torque the motor has.

my half bridge idled at 1500rpm

mine took a long time to break in cause my ceramic apex seals were 1 piece so it took a long time for it to start. now it starts in 2-3 cranks

Generally speaking, that info seems correct based on what i have seen. It's at least in the ballpark.

yeah BDC told me a bridge port hits harder and faster, and will spool small turbos so fast they run out of breath early

wish I would have looked into it earlier

this thread reminds me of that thread from a year or so back where the guy couldnt believe he lost to a built diesel.

hell even 500 hp isnt all that amazing now adays.

allow me to find the video of the 700hp colt vs. 1200 hp supra

the practial side of it is, where can you use a 500 hp car, unless you live in Wyoming? every city in this country is increasingly congested with cell phone toting soccer moms....350 in these cars is PLENTY

more people are going to end up dead pumping their ego

I'll stick with the YZF-R1 in the peaceful mountains of NC, and go faster than any of these bloated 500 hp gas guzzling monsters for a whole lot less $$$....you spend all that money for a few precious seconds of running someone on a freeway (illegally), it's kind of dumb

it's the age of excess

You can use that kinda power in lots of the south. Texas and Oklahoma definitely.

Hell, even in NJ you can hit 140 certain highways at night when traffic is sparse......

reliable source (mazda rx7 performance handbook)

ive seen were some say that 400hp on a rx7 is more than enough power. That was true back then. but now these amg 600hp mercedes, 510hp viper, 505hp vette, 400hp isnt enough. (thus the reason why i went with the bridge)

on my t2, i had full spool by 2500rpmish on half bridge.

and i know PLENTY of spots around here where you can get up in the high speeds. i also know where there are some kick *** curvy roads.

Matter of oppinion. Your YZF-R1 may be faster and get better gas mileage, but lets look at what it dosent do...

Drive in rain
Provide any sort of protection from an accident
Cool you off on hot days
Warm you up on cold days
Help your back
Carry anything
etc....

I could probably make the list alot longer, but im to lazy. And for the record its not even remotly hard to speed around here. The fastest I've ever gone in my car was on 485 in the middle of the day. Your on your bike would be more likely to end up dead because of a phone toting soccer mom or ego pumping than me in my FD. I'd take the FD over the bike anyday, nobody gives a **** how fast a bike is. Don't EVER compare a car to a bike.
