RICE RACING Posted March 30, 2019 Share Posted March 30, 2019 Good stuff ^ :) On the other end of the scale did an EFR7064 the other day on a 1.8lt (460rwhp on homodynamics roller) but running car weight is 700kg region and small frontal area means it runs rings around anything else :).

welshy_32ZILA Posted March 30, 2019 Share Posted March 30, 2019 Hey Rice, (apologies Ive not caught your name) Considering my manifold is a true split pulse and the housing is also split pulse which side of the housing should i be drilling and tapping to take the emap reading from? Surely thered be a small difference between the smaller scroll and the larger scroll pressure wise when spooling the turbo?

welshy_32ZILA Posted March 30, 2019 Share Posted March 30, 2019 (edited) True Split pulse 6boost manifold with twin 40mm TS gates external and indvidual egt's. I fabbed my own 4" SS exhaust with a "Hi-flow" cat and 2 off Magnaflow mufflers along with all the 3" intercooler piping. Changed from a old 68mm PWR cooler to a CPC 90mm 600x300mm core. (was hard to bring myself to weld to the billet end tanks). Its a basic 2.6 build. eagle rods, CP pistons, actually i need to check when i get home if it has main studs and Head studs... lol fingers crossed. Im thinking the head is gonna be the big restriction.

If you are going to run E85 and aren't shy of boost then it should be capable of some solid numbers still I'm guessing. So what hotside on the turbo, 1.05?

welshy_32ZILA Posted March 30, 2019 Share Posted March 30, 2019 (edited) Yea e85 and 1.05 split on the rear. Im guessing the boost may start with a 3. but Between the head, and the inj being at 65/70ish% duty with the -5s id say they may temporarily hold us back aswell.

sneakey pete Posted March 30, 2019 Share Posted March 30, 2019 Just bump the base pressure up a bit. and get cams with another 2mm of lift, that'll help.

burn4005 Posted March 31, 2019 Share Posted March 31, 2019 (edited) Interesting. I was at 76.5% duty on same injectors on e85 at 285kpa on an 8374 1.05.

Ok so u run them in the manifold itlself. Even my manifold is split so the pressure reading wpuld be only from 3 cyl. Yea I see most run an accumulator/filter setup to smooth the small pressure rises from the cycling/firing of each cylinder. And obviously filter to prevent exhaust soot clogging the sensor.

That was a 491awkw run on a 2.62l lambda of 0.8 though. Quite interesting looking at it all there, his target lambda is arguably on the rich side - and he's ~5% rich of that target (ie, it's running 10.7:1 "gas scale" AFR). It could be that rich of target due to the fact he is running at part throttle at that long point, but at face value if he was running your lambda at the same MAP he'd be <70% duty at this point which isn't so bad. Also, those Bosch injectors are "1650cc @ 4bar" while the target differential pressure appears to be 3.2bar, and it's around 3.1bar at that time spot. One way or another, there should be room for AT LEAST 10% more power with that fuel system which isn't all bad Edited March 31, 2019 by Lithium Link to comment https://www.sau.com.au/forums/topic/466636-borg-warner-efr-series-turbos-v-20/page/101/#findComment-7901911 Share on other sites More sharing options...
burn4005 Posted March 31, 2019 Share Posted March 31, 2019 (edited) heres a run of mine during the tuning process for comparisons sake: we didn't have the pump PWM speed control map set up correctly for a flat fuel pressure, and base pressure was a bit low. closed loop fuel was bang on the lambda target regardless (+4.5% fuel enrichment and -3.5% closed loop lambda enrichment. this run was at E75, but in my tune anything over E70 is full boost, full timing. I've been trying to get emtron to fix the fuel rate calculation speed as it's quite a useful runtime for fuel demand, but for some reason its refreshing very slowly in the log.
