Take those dyno graphs on that site with a grain of salt. Who knows how those cars were tuned or tuned at all. That is probably the worst looking T-78 graph I have seen. If you want to see a good one look here http://www.rx-7store.net/rx7pics/zaviersdynograph.jpg
If you superimpose that over the others the T-78 is making more power throught the entire power band.

Since silver93tt WORKS with Steve Kan, who replied earlier as to why that T78 might look so bad, perhaps they may have done some tuning
Tony, aren't you supposed to have a GT40R by now?

Come to Columbus, Ohio and you can ride in a T78 followed by a GT35R. I'd tell you which one would win from a dig or a pull but I don't want to go there right now

Really I am not concerned with making "more power" Justin.
450 would be all I can stand. Unless you rope the boost in your just gonna slide all over the place anyway. Mine gets a bit silly and I'm using twins. Not to mention I dont see any other Fds in my neck of the woods anyway let alone a T-78 one. I wouldn't mind getting pulled on some by a Fd running a T78. Its not like at 400 plus HP anyone should be ashamed of their ride. I doubt I would see more than maybe 3-4 cars that would ever best me with that set up in my end of DC on the streets. In my county I would say maybe 2-3 guys could do that. What I want is to get to the top end of 4th gear before anyone else. Best thing I have seen so far for that is the 35r. Yea the rebuild cartridge is about a grand but they last longer from what I read so you shouldn't need to rebuild as often. I'm not sold anywher yet but I wouldnt mind being the only guy round Maryland rollin on a 35r.
I am just not feeling the to4.

Whats the circumstances around that?
You talking 1/4 mile?
Roll on, from what speed and backing off at what speed etc etc..
I am not against T-78 at all if that is the way to go then that is the way to go. I just want to be sure that I am not trying to spool up a T-78 while Johnny Mullet and his supercharged 'Stang aren't walking away while I am waiting for boost to build.
Whats the BB T78 equivalent, the G40r?

I have the gt35r or 35/40 whichever you want to call it. Personally for street driving I love it. I had my large street ported motor tuned to 1 bar earlier in the fall and I have full boost at about 3500 rpm or so. I plan to tune to approximately 17 on pump gas this spring with new wheels/tires, as this was what would not allow me to safely tune past 1 bar. I was told that this turbo really doesn't become efficient until approximately 17 psi. I suppose if your port were aggresive enough it could spool the T-78 a bit earlier than normal but for my money if the 35r weren't enough I would probably go with the 40r as it should produce about the same amount of power as the T-78 give or take some but spool quicker as it is BB. Honestly call Sean at A-Spec and talk to him about the setups you are considering he'll be able to help set you straight.

Mind you that was tuned for 1 bar, but yeah my full boost is right around 3500 or shortly after. I haven't driven the car in a couple of months so I'm not totally sure on the exact rpm level. Like I said though I'm incredibly happy with it especially since my car sees a lot of street driving and some Auto-X. If you're looking for 400 or a bit above that with the possibility to push towards 450 with an aggresive port so on and so forth the 35r might be your weapon of choice.

Full boost by 3500?
