New BW EFR Turbo Thread

yeah, im not ecstatic about EWG...but the more i look at it the capabilities of the turbo it looks worthwhile. most graphs i can find show it should spool around 4k, and its cheaper and probably easily more reliable than a stock frame piece.
is inconel as fragile when it comes to speed as the gamma-ti?

Here you go guys.
7064 Kelford 272 cams syvecs S6 2.3 ltr Magnus inlet. 98 Ron Fuel.
Spool looks late due to cam timing, almost 1000 rpm later than the 7163 with 264 cams. It could go back on the dyno week beginning 16th to move the power curve left maybe 400rpm.
Dyno temps on the day were really hot which is why the power dropped off at the top end. Currently the core is rated to 550hp max but really needs to be replaced with a 700bhp rated core.
FYI i have been trying to achieve a 500/500 hp car with a flat torque curve till redline.
As a comparison - 7064 Kelford 264 cams Link G4+ 2.3 ltr Magnus inlet. 98 Ron Fuel.

You lost 30lb-ft at 3000rpm (was 180, now 150),
You lost 100lb-ft at 3500rpm, (was 340, now 240),
You lost 70lb-ft at 4000rpm, (was 470, now 400),
Than its gains,
You gained 40lb-ft at 4500rpm (was 490, now 530)
We generally all think you should be able to improve spool: its a 2.3.
Issue is that dyno's can be run in many modes, so that is why you should be testing on the road.
Test it on the road, let us know how it behaves/spools on the road.
There is always 7670 in worst case.

Here's my recent setup on a stock block on 92 oct:
7670 EWG 1.05 ar
ETS twin scroll kit
ETS 3" intercooler
Walbro 255
FIC 1100
GSC S1
Stock intake manifold and throttle body
Thanks to the guys at English Racing and ETS!

I have to disagree with Nemsin, 7670 not working well on 2.0:
I personally enjoyed an E9 with basic built block (people have pushed stock blocks just as hard and harder, so this was nothing un-attainable to the OP)
The car was built recently by Speedelement in San Jose,
E9 2.0 with Full Race EFR7670 1.05 AR
Trick is it was on E85.
Oh my GOD, this was simply stupid, stupid responsive, and stupid fast.
I have fast cars, so am not Prius driver never driven anything like Evo.
Full boost by 3600rpm, tuned to 26psi on Dynojet, it was pushing low 500's.
I have to check the dyno sheets/data I have somewhere.
It eventually made 600whp circa at 34psi..on 2.0 on E85 street tune.
But at 26psi at making low 500's it was absolute mad crazy car already.
On 92 pump 450whp...it should be plenty rapid, and hopefully full boost by 3700-3800rpm.
We'll watch this space for more.

I would be seriously inclined to believe the BW chra would last longer. Stock chra turbos seem to have a weak spot after having 3, to serious abuse and in one case no perceived abuse. While we aren't moving to borg warner , I think the gains are what you anticipate or see on the dyno, but the benefits are far reaching.
