Do we expect there to be any advantage in spool characteristics with this vs internal wastgate on a turbo like the EFRs?

These will not respond as fast as the IWG( bigger and long runners).

One will be able to hold very low boost, and make more peak rwhp vs the iwg kits.

The test car has hit the rollers and is making 479rwhp at 14 psi with the EFR 9180 1.45 . This is just a run in tune at low boost( 10 AFR on E85). Car is also on a dynodynamics in non shout out mode. In my experience this is about 12% lower than a dynojet. Car will be run upwards of 25+psi after some shakedowns. I am also told its making 8 psi by 2000RPMS. More data to follow. This car is logging shaft speed, egt, and emap per runner too.

I think we are probably still 60 days out from that. The foundry is a little behind schedule.

Below you can see fitment with the EFR 9180 on the RHD chassis. Fitment is identical to our welded version FYI.

Should have a proper video on Monday, and maybe even a 20 psi dyno run.
