EFR Turbo
 

Just wanting to see how many people are running the Bog Warner EFR turbos in their cars? Please list what turbo size and how many lbs of boost you are running and gas used. Im using the EFR 7064 with E85 471wrhp@16lbs of boost on stock motor. Motor is built now with Dynasty fuel return system with fuel rails. Just waiting to break the motor in before turning boost up.

Nice numbers... I don't have a EFR yet, but plan on purchasing a 7670 in a couple months.

Subbed

Post is useless without torque number.

Here is the link to my dyno. The TQ was 368 i think.

I guess nobody really running the efr turbo.

Any gearbox issues?

Some have claimed to have blown several with power similar to yours.

Nope, haven't had any issues yet. But how ever i only go fast on a freeway and not from a dead stop. But i might blow the tranny in a few days once im done breaking in this new motor and turning up the boost.

Mine is going on now. 6758.

I won't be running big boost anytime soon though as I'm saving for a bigger house before I get a new motor

Torque is pretty low. What compression are you running? Didn't see it anywhere.

10:1

i've been toying with the idea..
when do you start building boost? and when do you hit full boost?

I was considering the 71/63 .80 offered by full race on their kits(t4 twinscroll). What's the difference besides the wheel size between the 70 and the 71.. i see the 7064 costs almost double on FR's kit. Hows the performance of these, are you using the boost controller solenoid on the comp housing, is the bov any good? How or better yet where do you connect it to on our cars?

I'll let you know in a few days. just finished breaking in motor and will post new numbers once put on dyno.

There shouldn't be any real price difference between the 7064 and the 7163. My understanding is that the 7163 is new for 2014. The housing options can change the price a little:

For some reason when selecting the turbos on the FT86 kit, the difference is clear but maybe im missing something... could be a typo i dont know but both t4 iwg selections the 7064 is +2,263 and the 71/63 is $1,729 :iono:

That doesn't look like "almost double" the price difference to me. Go with the newer and cheaper 7163. :bonk: The difference is $8 on the s2k kit:

i know i just looked at the 1 and the 2 in the front figure lol. :thumbup: May have to ask geoff why the gap on the FT platform. Thanks anyways.

I might sell this one and go 2 sizes up if i dont get the number i want.

Just curious, but what is the magic number you are looking for and what made you decided that particular number is what you needed?

"reading sig" that has to feel nice, 471whp.. man, lol i may not be even breaking 190whp,lmao and feel quick what a joke. Keep posting.

I want 600+ but originally 550hp. And maybe 700hp later on once I build the tranny.

You mean when you buy a V160/V161 or aftermarket racing dogbox tranny. lol.

Naw going to do my own custom tranny just like my turbo setup. I like to be different. Or unless they drop that price.
