Display MoreLike @rabtech said, so far on E10 or better the stock pump has been holding fuel pressure just fine.
Don't worry @lrobbi we have some love coming for the supercharger kits after Maggie Valley this year, Mr.Bob is coming back with us for a couple long days on the dyno.
The Borg Warner EFR's do use an internal wastegat on the turbo. The internal wastegate on the EFR's holds boost amazingly well, the boost curves on the first ones we have been doing and running shoot right up to the target pressure and then are just a level line all the way until you let off the gas, no overshoot or wavering.
The fitment testing on the system has gone very well, the next stop is a trip out to Slingmods in just over a week for an installation out there and a couple days of tuning on the streets of LA with the new turbo. Here is what the final kit looks like -
We have most all of the parts back from production, we are just working to secure timeframe on the actual turbo cores for the first batch and once we have that finalized we will be releasing more information and start pre-orders for the system.
Welter has also now completely developed a downtube from our turbo to their exhaust systems.
Please let me know when you are coming to Cali @Dave@DDMWorks would love for you to look at mine as well! Still trying to get that detonation issue worked out and had @TravAZ hook up and run numbers for me in Vegas.
