Robi called me after you guys got the car dynoed, he was really excited!! he seemed blown away by the power delivery and the powerband this combination produced. Buschur and I have disagreed on many topics, but we can both agree he builds one hell of a 4G motor and Full-Race builds an excellent turbokit. Great to hear you love the setup, your enthusiasm is motivating me to get my car finished! This 7670 is what ive been planning to use on my evo, a phenomenal all-around setup that plants you in the back of the seat instantly.. ill probably run the internal WG just to see what the limits are

thanks for the vid, looks like fun!! i cant wait to get my evo going with the internal-wg EFR although mine will be twinscroll it will also be on E85

that is correct- you require the high boost actuator for boost levels above this level . In fact i recommend the high boost actuators to all of our evo internal WG customers (min boost on the high boost actuator is ~19psi)... we have these in stock right now along with Full-Race billet aluminum BOV cover plates if you need

michael - for a 2.7L at 25psi, the 7670 will work well. However if you planned to go to 28+psi take a peek at the matchbot, you will probably want to step up to the 8374 if shooting for 28+ psi, since its approaching the wheel speed limits on the 7670

 

Geoff,
You're supposed to give Mike BAD advice.

 

Geoff, what is the minimum amount of boost you can run with the high pressure actuator?

What has the internal BOV been tested to? Does it have any limits?

 

Both good questions project!

 

the high pressure actuator starts around 18/19psi with 2mm preload (minimum amount). It can go up to 32/33psi with electronic boost control set to full spill. For increased boost levels OR for more control, we are just about to release a dual-port internal wastegate actuator that behaves similarly to an external gate "push/pull"

the BOV is tested thoroughly by BW. Ill ask for permission to post detail

 

Thanks geoff! Can't wait to play with the efr!!!

 

That internal wastegate info is very good.
Does that mean with the wastegate control line disconnected, it will only hold a maximum of 32/33psi? (just to make it clear)

What kind of numbers do you get with the "medium" wastegate? 11-12psi at 2mm preload with a max of about 23-24? If this is the case, if there any way to make it hold higher boost? External spring maybe?

Cheers, Mike

 

Geoff,
I missed the info on how are evo owners going to fit the internal-wg EFR on the cars, more so the twinscroll ones.
I remember you were considering a top-mount manifold, what's the option at the moment?

 

^^^this will be a brand new Full-Race Evo turbokit that will debut at SEMA 2011. Top-Mount, EFR twinscroll, Internal Wastegate. A/C compatible and full-length rad compatible, but requires a custom evo6 rad be used. Ill post photos up as we get closer to the release and we get closer to the EFRs shipping. This is the setup i plan to run in my personal evo - some updates to my build thread: Full-Race Geoff's Evo Build and will put photos of the turbokit there on my car once its ready

YES - if the wastegate line is disconnected from the High boost canister you should see a maximum boost level of 32/33psi

the Medium Boost canister is meant for 11-12psi and at full spill (aka wastegate line disconnected) it can get up to 20/21 psi but some people have gone slightly higher.

The way to make it hold higher boost is to replace it with the High Boost canister (just stamped steel and a spring approx. $56) or one of our dual port push/pull actuators (billet alu with a piston, seal, and multiple springs $160)

edit: ill work on updating our website over the next two weeks so everyone has a better understanding on this

 

Do you really expect a answer on the questions?

 

u are crazy man..

 

Does anyone know where to get an aluminium v-band flange to suit the compressor cover outlet of the 8374/9180? All of the flanges I can find in 2.5" are not the correct dimensions to fit.

 

Thanks and let us know on the internal bov, if it can hold 40-50 psi this will probably put me over the edge on buying my friends.

 

No one has any news to tell?

 

Hi, which model of EFR you are waiting for?

I am still waiting for my 8374 twinscroll since last Dec too.

Anyone else in the forum still waiting for the same turbo as mine?
