Boondocker Tial upgrade

Does anyone have a BD with a TIAL housing and external wastegate? This seems like a better setup than the standard cast iron rustbucket.

Any performance difference, or all just bling?

tial housing

I was looking into switching to a tial housing and the external gate a month ago or so, I couldn't find anyone with an opinion for a sled but I found a guy on a some honda forum that says he dyno tested both housings on a lil honda, don't remember what model or motor but I do remember the turbo was from the GT28 family.. anyway if I remember right he said the tial housing would reach full boost about 200 RPM sooner then the garrett housing, I belive he was running around 20 lbs or so in his race motor?. I can't find the thread right now but if I do, ill post a link.
Hopefully someone that has one on a sled will chime in with some feed back, I am curious also..

The Tial housing does make for better flow and the external wastegate makes for better throttle response i run them on my race gas kits they do make it better in some areas if you are running 8#s or lower it is all bling pm me if your interested in doing one i can set you up

Im running one 2871 the external wastegate helps keep the motor in tune.the other difference is the standard needs to run 3 lbs more boost to equal a tial ovs sells the tial u also get faster spool up with the tial
