HarrisRacing Posted July 26, 2018 Share Posted July 26, 2018 Car arrives at shop with stock RB26 on stock turbos. Has installed a PNP Haltech and a rough, rich tune. 14 psi on top end...laggy for sure. I knew we were swapping them so I didn't try hard here. 3 weeks later: Billet oil pump gears Tomei Cam Gears (rolled in pretty well) My old EFR 8374 .92 and 6 boost divided IWGmanifold 3" exhaust Still on 93 octane and still on Haltech basemap timing (still tuning just ran out of time last night) 15-16 psi boost (same as his car when arrived). This is a FANTASTIC turbo for an RB26! 4 1 Link to comment https://www.sau.com.au/forums/topic/466636-borg-warner-efr-series-turbos-v-20/page/83/#findComment-7881972 Share on other sites More sharing options...

I'm guessing that is more to do with torque calculation/smoothing and retarder control than reality? I can't think of any reason why torque and MAP wouldn't correlate directly. why would torque lag it?

I can't think of any reason why torque and MAP wouldn't correlate directly. why would torque lag it? Yuh, hence why I said what I said. Without knowing whether it lines up on that car/dyno combo, you don't quite have enough info to assume. FWIW, torque climbs from low to max in an NA....there is no boost to "set" the torque level. That efficiency/breathing function is still present in a turbo engine too. So if the boost comes up to max before the engine has reached its inherent torque plateau, then the torque should still lag the boost.

nicknack Posted July 27, 2018 Share Posted July 27, 2018 Got the SR22VET tuned today with the .92 IWG 7670. It was doing 300kw at 15psi. Ended with 408kw at 26psi tapering to 23psi (intentionally). 300kw at the wheel at 4.5k and revving to 8.5k is going to be fun.

Deano 1 Posted July 30, 2018 Share Posted July 30, 2018 my 9180 makes 500kw atw on 26psi with a run in tune on my new engine. Be interesting to see what she makes when we turn it up. But they make 500 easy. Link to comment https://www.sau.com.au/forums/topic/466636-borg-warner-efr-series-turbos-v-20/page/83/#findComment-7882247 Share on other sites More sharing options...

Below is the comparison on SAME dyno (only days apart) to my 1991 GTR. Here is my stock RB26 GT2860-7 car. It has Greddy downpipe, HKS super Drager exhaust, Tomei cam gears rolled in about 6 deg, and now has hard inlet pipes that I built last week and a Haltech Platinum pnp (the rev2 is nice!!). I modified fuel rail for -6 inlet on rear and upgraded fuel pump with FIC 850cc drop-ins. On stock AFM's and just raising boost to 18psi it was 384 whp before cutting due to AFM overrun. It did ~ 300 whp at 9-10 psi boost. New dyno on Haltech at 20.5 psi and 3 deg added to base haltech timing = 456 whp. I want you guys to note that while it "hangs" with the 8374 EFR IWG .92 on boost threshold on a non-load bearing dyno, when driving the two cars the single completely stomps the twins on response. You can spool sooner, run less boost, and make more power. The 8374 car on 14 psi makes the same power as the -7 car does on 19-20 psi...It is a no-brainer for anyone that thinks that -7 are acceptable boost threshold and lag turbos then the 8374 will beat the pants off of them everywhere.

RICE RACING Posted July 30, 2018 Share Posted July 30, 2018 (edited) Here is 9180 on 13B street port engine (the video I put up of it on idle a page or so back). Turbo is max response set up with adequate power range (~700bhp engine), makes for a fast car in a RX7 weight/size. Power band is good, but it can only do so much, 120k turbo speed on this one, we have run higher on other cars though. Its got a nice spread of power and will do 100 to 200kph in one gear in under 5 seconds. I also include data on phase + anti phase control, we can run a bit more boost if required, and no drop off to 9000rpm (beauty of an advanced ECU).

I am going to be using a built and ported head as well as flex fuel. The only thing that worries me is the turbo running out of puff on the top end. Is there nothing in between a 1.01 and a 1.45? I really dont want to have to stick a 1.45 in there. I know a friend that runs one and is rather laggy, on a 3.2.
