There is bugger all people running EFR's fulls stop and I'm keen to hear peoples opinions with real world experience. Thinking of going 9180 myself.

The technology in the EFR leaves Precision for dead. It's a shame to hear about the failure posted above....but then again mummba only changed as the Precision failed.There is a budget Borg Warner version out soon called the S300 SX-E. It's a T4 platform and journal bearing but there is a whole lot of good about it!! 2 Link to comment https://www.fordxr6turbo.com/forum/topic/90986-fg-xr6t-just-went-596rwkw-800rwhp/page/2/#findComment-1557971 Share on other sites More sharing options...

Interested in hearing more!!Yeah, had 2 separate issues causing over boost.The first one was boost spike on gear changes in 3rd & 4th. We believe from the blow off valve being small. Boost was spiking 5+ psi.The second was a restriction from the intercooler at high rpm. We were still using a PW stepped cooler at this stage, had a 6 psi difference from hot to cold side of the intercooler.The result was a spike to 30+ psi when there should have been 21psi.

I don't have a BOV and don't get any spikes. My mates with the 9180 just uses the EFR BOV and he has no dramas either. It also looks like the boost spikes prior to the throttle closing. It might be something more sinister so keep poking around.

I know little about them so can't comment much, but it's funny you don't see many of them round if they have better technology/drivability etc than the precision turbo's. Because the last 2 years has been raving on about how precision are more versatile and better than the garretts....

The efr range is expensive compared to the precisions.You can get good results with the precisions or garretts so many people think why spend more for marginal benefits?
