cool stuff

 

Chris - if one already has an EF4, could arrangements be made to directly purchase the new TS actuator from your stock? My order has been floating for 2 weeks and the last I was told is that they are on back order.

 

Have you already ordered one sir? Shoot me a pm with your details.

 

PM sent. Thanks!

 

Thread cleaned up a little so we can stay a little more on-topic.

Side note, one guy is apparently having an issue with boost creep:

Has anyone gotten any numbers for the EF1? Interested in a mild track day car setup that might be a little perkier than the regular IX turbo.

 

EF1 will net you more power than an EVO IX turbo (not a ton) but you will have a much longer power curve than the EVO IX turbo could over supply. For a mild track day car (~400whp) the EF1 would be a great choice.

 

400 whp sounds like a lot to me, but our local mustang dyno reads tuned stock turbo IXs at around 320-330whp at most. So I guess for comparison's sake about how much whp gains could one expect with a EF1 on 93? And less top end taper? Thanks!

 

~400whp means around 400whp. So anything 380-420 is what I would say. I can't say how much you would gain as I don't know what mods those 320-330whp EVO IX turbo cars you mentioned have.

 

Adam was probably thinking dynojet numbers as well, and was most certainly thinking E85. Mustang numbers on 93 octane I would expect ~10% gain from the EF1 with very similar spool.

 

Chris, thanks for responding... that sounds very enticing. Have you guys done any dynos on one yet? I looked around, but couldn't seem to dig any up.

 

Only some DSM results and those are much smaller single scroll turbine housings

 

e85 is always on my brain, but with supporting mods the EF1 will make ~375ish on pump.

 

More EF2 results

Nice, that is a good post!
