Less mass...would be cast then. If you duplicate two wheels, one in billet, one in cast, the cast will be lighter. Less dense. Billet does not have casting pores like cast wheels.

It can come with 80mm up to 106mm and cast and billet counter parts. Also with the HP ET-R wheels as well....

Is the TV84 what is used on a Detroit 8V92??? Or is that a AiResearch or Garrett thumper type charger???

91mm flows a little over 150 lbs/min
94mm flows about 160 lbs/min
106mm flows about 180 lbs/min
This is just rough idea from Garrett's website...
I have heard that a 10% gain in comp. flow with the billet ETR wheels, (11 full blades, no half blades like what he pictured) I have seen no dyno results that prove this, and anyone that I know that tried one did not have the results that they claim... They look BADA$$ though!
I think a GT45 externally wastegated into a 106mm GT55 would be a lot of fun...

Yes sounds really fun and BIG $$$$$$
hopefully next year there will be a GT55 on the bottom....... or just find a turbo sponsor......... Jose

The 91-98mm Garrett thumper with the F-trim exhaust and the .9 or 1.0 A/R would probably work for you. I think the 91mm is only $2100 or $2200 new... I say only, but it is a cheaper alternative to the GT55($2600-$2700), but it doesn't spool quite as well from what I'm told...but with twins that isn't that big of an issue!
Where did you get your TV84? Do you know what it came off of?
Well Jose (dr turbo) has convinced me that the gt 55 while being alittle more $$$ is the best of the offerings- spool and flow
i picked up the tv84 new off of this forum..... my 84 is actually with Jose @ FI right now getting the 91mm upgrade
i will check my notes but i think the TV was off of the detroit 16v

All of the 16V's are basically 2 8V92's bolted front to back... They use 2 blowers and 2 turbos, so they should be the same.
They were used on several DDC apps. Most will have AiResearch on the cover
The GT55 is around the same price as the S500SX with the standard wheels on the GT55. If you want the ET-R or the DBB or a combination of the two it does get more $$$. Ask Ron A on this forum what he thinks of the GT55 now. He was a long time Borg Warner only man....we made a believer out of him with the GT47 and then the GT55 he has now. They simply work, spool fast, and are super efficient.
The 91-106mm thumpers are a little cheaper, but they are also a little slower to respond. BUT, nothing, and I mean nothing matches them on turbine flow that is performance based.
The GT55 billet 106 DBB is a bad mofo....we have made some STUPID power with this turbo and it simply won't die. Don't forget also about the S500SX's. We carry them as well and though they don't quite flow as well on the turbine side as the GT55 their comp wheels are up to the task.

By billet 106mm I assume you mean ETR... What kind of power have you seen? What kind of boost?
How much does it cost to upgrade a DBB GT55 to the billet 106mm that u speak of? PM me if u don't want to post on here...
The 106 billet is the 6 blade unit. The 106 GT55 DBB billet is a unique animal since you can not use the 106 wheel on the other DBB GT55's. The GT55 106 billet uses a 1/2" shaft.....you read right...1/2" shaft on the stub....thats larger then anything else out there....the unit simply will not die. We have ran them on tractors and on huge diesels even as a single making stupid power and spinning the unit to the moon...never have had one come apart.
They are Garrett built.....we CNC them here in house. We build them from 88 to 115mm.

What is the smallest high pressure turbo you'd wanna run with a 91 or 94mm gt55 without choking it out in a racing app? Assuming plenty of ext w/g. Been seeing alot of 351cw/s595 setups out there recently that are eatin up 1000hp and spooling very fast. Seems like the comp on the manifold charger would be a hell of a restriction once the primary lit.
