Roy Posted July 30, 2016 Share Posted July 30, 2016 So does anyone know a 7670 result out there that makes it a no brainer decision? I have spent this morning again cruising google and can only find one old article which supports what i was saying about the SR20 comparison. http://blog.perrinperformance.com/borg-warner-efr7670-turbo-exposed-and-tuned-part-2/ I did see some good results on a std EVO X ... i think i am going to stick with what i got Link to comment https://www.sau.com.au/forums/topic/341890-closed-borg-warner-efr-series-turbos/page/137/#findComment-7761964 Share on other sites More sharing options...

Roy Posted July 30, 2016 Share Posted July 30, 2016 Yeh, there are some Evo 8 thru 10 results that tempt me..but bascally its 3076 response and power with better transient response. Which is ....wishy washy stuff. Tempted to just go 7163 and give it a gut full and at least habe it all in...but that is wooftah 427ci cave man stuff. Its a turbo car....it shoudl be about soaring top end Link to comment https://www.sau.com.au/forums/topic/341890-closed-borg-warner-efr-series-turbos/page/137/#findComment-7761980 Share on other sites More sharing options...
bri73y Posted July 30, 2016 Share Posted July 30, 2016 I went from a HTA3076 to a 7670 on my RB25. Dyno graph in this thread somewhere of initial tune. Picked up power everywhere, much better car for the change. Approx 75hp gain (top end, now) since final tune with minimal loss down low.

Roy Posted July 30, 2016 Share Posted July 30, 2016 87mm bore, 9:1 comp, Kelford 272x9.33 cams, OS valves. What manifolds is the lil RB25 running? Its the T4 TS 1.05 housing?

bri73y Posted July 30, 2016 Share Posted July 30, 2016 6boost, 1.05ts. I have since added heavier waste gate springs and picked up another 30hp and had a slight improvement in response. Next job will be to replace the cooler piping as it goes from 2.5 turbo exit to 4 back to 3 for cooler then exits as 3 straight into 4 upto inlet manifold. It's not ideal.

Mick_o Posted July 30, 2016 Share Posted July 30, 2016 Where are you getting this info Roy lol? A 7670 will punch holes in a GTX & GT3076! Ive never heard of an GT's going 410kw?350-360kw max. Yeah the GTX will blow 400kw but its ALOT laggier! Whats this its "only transient and response" its better? Transient response on the track and on the street is king! SAU is being a turd. If it lets me i will load a GTX3076 vs 7670 result for you. Both are T3 .82/.83 results on an evo.
