Anyone interested in a downpipe/midpipe combo? It was modded to fit the efr, but it fits all t.s. t4 full-race kits.

 

It's Alive!

Damn those cams sound mean!

I need to get me a set.

 

good stuff eric - which cams are you using? sounds healthy!

the materials and features are "game changing" for street and road race/auto-x cars, that's whats special.. The wait is what's making people go crazy

 

unobtainium. lol.

 

is anyone running the 7670 on a 2.0 set up? I'm sold on the BW and willing to wait to get one. Just wanted to see if anyone is running the 7670 or 7064 on a 2.0?

 

I am, 10:1, Cbre ported head,s2 cams.

I will post a video of it later today. Spool up is crazy fast. Crusing in 4th on the free way, changing throttle from 30% to 35% it jumps to 17psi if your not careful. Starts building boost in the low 3k. I still need to tune the damn thing, going mess with it later this evening.

Edit- I have the 7670 external gate, with divided t4 1.05 a/r

 

I wonder which would spool faster?
7064 single scroll or
7670 twin scroll?

 

Can I get a headcount from the guys who have any version of EFR? I've been trying to follow this thread for over a year, but with over 1900 posts it's hard to keep track.

Who has one?

 

That's awesome.. i was looking at the smaller .83 A/R T3 7670 internal gate. i have been researching the EFR series for the past six months... i was originally sold on the 6758.. but i figure if i ever decide to build my Daily Driver and wanna see more power 7670 would be the way to go.. im curious to see the 7670 spool on stock internals. ..

 

i second that... im torn between the two..

 

better off starting a new thread with a poll, it will get lost in here.

 

Link it here if you do that please.

 

It'd be an interesting poll, probably a few options would be worth it if it gets set up like:

- Ordered but not received
- Received, not installed/tuned
- Turbo installed, failure
- Turbo installed and tuned, no problems
- Turbo installed and tuned, no problems, awesome result

 

I should hopefully be able to give you some numbers of a 7064 T4 1.05 on a 2L next week so long as my fabricator gets done with my manifold. Numbers wont be massive as for the time being im only running it on a stock motor so am not going to push it to hard.

As a reference, an Evo X Time Attack car over here got tuned last week with a 7670 T4 1.05 2L built motor, Cosworth Head, Full-race manifold. made 357kw(480hp) at the wheels on 24psi on a Dyno Dynamics. Pretty soft tune just for testing to get some laps on the car before World Time Attack next week. Also was making 24psi at 3100-3200 rpm. Cant remember what gear that was in tho.
