i hate to double post, but i put this in the drifting forum...

if you could check it out, i'm curious as to why this test piple in the video had a stepped insert...

19 views, no answers...
i assume no one has d/l'd the video?

currently downloading ... see you tomorrow ^^

ive got the video...i love it too...too bad i cant understand japanese...

the pipe insert is by k-style (something you probly already knew)...sorry im not of more help...i dled the video yesterday and ive been trying a few different techniques to find out about it...but i havent found anything yet...sorry :(

thank you...
i appreciate it...
i'm not dying to find out, but i was intrigued, so i figured i'd ask...

thanks again, i'm curious...

tried to download it.... said the site is down :(

hmm my download is still running though, currently @63%

interesting...
when i dl'd it, it took 2 hours... but that was super duper fast on a double t1 line...
what i said is basically what's in the video...
so why would they want a stepped insert in the test pipe?

keep the turbo spooling with some reduction for low rpm boost response?

i dunno...

Yeah maybe more back-pressure...though you would think at higher rpms it would be counter-productive since it impeeds the flow of exhaust gases and heat from the engine bay. I dunno...just a guess :lol:

Right on. Don't see what other good it'd do.

I have no clue either :D but the video was nice anyways

I love the mr2 and mkIII supra drifting especially...

the trueno/corolla accident was pretty funny when that asian guy was kicking the car and the door that fell off...
