New BW EFR Turbo Thread
#121
If the 7670 is run outside the efficiency islands on the map, but using E85 and a large, efficient intercooler, what would you expect the upper limit of lbs/min it would flow will be? Is that the 64 lbs/min that BW uses in their literature? Where is the choke point for the 7670?
I honestly feel a 7670 will be plenty for me and my car. I feel the 8374 would be a real handful - I'd sooner drive the 7670 flat out than attempting to tame the 8734 (power is nothing without control and all that)...Re headwork - I've opted for standard sized valves on a fully ported cnc head. This will be going on a fully built motor that should take what I can throw at it
april will be a good time frame!

The bearing housing is made of cast iron and it can rust if not coated. The customer can paint it, if desired, and the paint will “stay put” since the CHRA actually runs pretty cool with the water. On our cars we coat them with WD40 from time to time and they stay looking pretty nice, no rust

What i really like about these new turbos are the Turbines in them.
If what I am guessing is right, they are using Gamma Titanium Aluminide:
http://en.wikipedia.org/wiki/Titanium_aluminide
Which is a step forward from the Titanium Nickel Alloy used in older turbines
A Stainless Steel turbine housing, and Dual Ceramic ball Bearings.

these are certainly not the same
singlescrolls continue to arrive, twinscrolls are taking some time as we wait for the housings

GT3582R vs BW EFR 8374, both with 0.82 exhaust housing.
Please bear in mind that a correction factor of "SAE" is very easy to botch with ambient air temp sensor placement, i'd be much happier with uncorrected.

GEOFF realistically what would be the price of a kit from your guys with this turbo. If it has a wastegate built in then that obviously lessens the cost.
I'm trying to determine pricing between this a regular ETS tubular kit with a HTA86 or a BR FF HTA86
Obviously the ETS kit would be cheapest. The BR kit will have some hidden costs (half width radiator, Civic Condensor and compressor for AC, etc).
I went on your site but I didn't see an option for the 8374 with you tubular manifold. It appears those would be the only things I would need. I already have upgraded IC and piping.
