Any real results of people using these ?
I will most definately be looking for something for a 2.35litre Subaru soon. If it can make around 800whp, I think that should be sufficient ( although I wouldnt say no to having the ability to make more ). Spool is of course important too.
Would be nice if it looked like a TN GTK series lol....they just look superb !!!!
At the quoted prices above....cost isnt an issue. Just the best.
Previous turbo was an ITS T70....how would that compare in physical size to the top spec 70mm ETT ?

even via PM if possible. I need as much real info as possible. Its for a friends car, which might actually get finished in the next few months !!! lol
The more info on their tried and tested abilities the better.
In performance terms, how do these units compare to say a GT42 ? T04Z ? GT4088...these are some units other UK guys are using, some running low 9's. A friend with a FWD car is doing 10.2 at 152mph on a HKS T04Z with some gas ( manual car, crap 60ft on that run !!!! ) Although he says its a lot laggier than the 4088 he had tried before that. But defo a lot more power up top...although slow to recover boost between shifts.

A crude guess would be 72 - 55 = 17 x 2 = 34 x 10 = 340 engine hp x .85 = 289 rwhp increas in a manual. You won't get that much of an increase though since nothing is 100%....are you willing to run the pr to get the full 72lbs of flow....probably not......I'd "guess" 150ish rwhp....won't know till ya do it!

Tiago we had planned on possibly asking for you to try a set but Jose and Jason were not comfortable yet until the units were throughly bashed and beat on by the small displacement motors which are the ones that really tend to destroy turbos. Since we didn't have all the data back at that time we didn't want to take a chance. Now that we have plenty of shaft speed data (thanks to Garretts new turbo speed system) we can see what is going on even more closely now.
