what else do you have with your setup?

 

75hp isenouf to push u around BUT its far away from stock twins

atlest in my opinion, i am more concerned with moving from a stop

without revving too high instead of ultimate power. and most singles

cant do that.

 

I made about 90-100 @ 3000 with the BNR's running seq and WAY to rich. My low rpm/ low boost was around 11 a/f and should have been about 12.5 a/f. I imagine with a little more tuning it would be about 100rwhp or so at 3000.

i woudl be interested in seeing the upgraded twins running seq and the switchover point dyno anyone?

 

Whoops, that was supposed to say NON seq!!!! I just noticed that I put seq on accedent...guess my fingers were too fast for my brain haha



Anyway, it wouldnt let me edit the post for some reason

i use an RX6 on a streetport. conservatively tuned it's about 320rwhp @10psi and 375@ 15psi. i use my car only for track (road racing/track events). no drags, no street. while overall i'd say the unit performs well and delivers plenty of power with little lag...... my two complaints are:



1. small turbine/turbine inlet/outlet.....i'm not a turbo wizard so i'm not sure about this....., but my exhaust manifold temps are consistently over 1800 degrees F despite perfect AFR's. i attribute this to the small turbine size/poor flow characteristics. i don't like those kinda temps.....may not bode well for turbo bearing longevity.



2. i recently blew out an exhaust manifold to turbine inlet gasket. two weeks later i'm still looking for one. even apexi is telling me they don't think they can get me one in less than several months! that kind of support is reason alone to NOT have this turbo as far as i'm concerned.



just some thoughts.

good luck

apex can do it but it will take a long fricken time, apexkw on the board had to order a new oil fitting for the turbo and it took like 3-4 months. a real pain in the ***

 

I put down 160 rear wheel hp at 3k rpms with my GT3540. almost 350rwhp by 4.5k rpms. Show me a T-78 doing that. On a NON-Ported Stock Reman.

 

You got a sheet for that? Stock Ports? If so Kudos for you man, but it does seem a little high. I have a non-ported reman so if you made this much power its good news for me! Got a sheet?

 

Hell yeah I got a sheet! And I was on my way to making more power but my boost controller was set to cut boost at 15.5 psi and I didnt realize it until i got home from the dyno. This is why my power drops off at 6k and starts to wave. This sheet also was while tuning. Its not a great representation of a tuned car but it does show what a 90% tuned car is putting down for #'s with this turbo. Kinda high? Kinda low I think. I made power power with my old motor when it was tuned. Both stock motors. Both with same Turbo. I may be wrong about power at 3k. Looks more like 170+. Either way it kicks everything *** down low. I think this is the perfect turbo for the rotary.
