D1 WTF

i have heard of a brab brab port or something like that.........is that a nick name for bridge port?

i understand what a bridge port looks like as i was shown one but......

if you do a bridge for on a REW (gen 3) will it way more stress on the engine and therfore decrease engine life?

what are the real advantages of a bridge port, performance/power wise?

could it happily be driven as a road car?

what is the difference between a 1/2 bridge port and a normal?

any other info that would need to be taken into account?

thanks in advance

Seems like the UK rotary world has gone bridgeport crazy! Soon everyones gonna have one.
Personally I\'d go for \'good\' street port 99% of the time.

I have a half bridge which is done on the secondaries, great for spooling up a big single. Way too much porting for twins, what turbo you have D1?

dont really know as i have never had it running properly since rebuild before the engine went pop.  i think about 4500- 5000rpm for full boost, from the short bit of driving i did after it was properly mapped.

obviously depending which boost setting i was in, 0.75 or 1 bar.

well after my half bridge Port Full boost was achieved 600 rpm lower hardly any lag at 3.5-3.6K, its making positive boost at 1600rpm. idle will be shot to bits I idle at 1.1K to 1.3K, but exiting corners is brilliant as I am on boost straight away

so is the brab brab the noise at idle?
so it isnt really so practical as a road car then, good for weekend toy and track car etc, or drag obviously.

does it stress the engine more then?

yep the Brap Brap is the noise it makes at idle

Dre uses his car everyday on the Port, I only drive the Rexy at weekends and during the week in the evenings sometimes, my car is too quick for the road at the mo not enough traction, plus my car is LOUD on boost.

Depends how you use your car and what you want the car to do, The extended street port I had was more then enough for the road, Bridge port is ideal for track work coming out of corners
