I don't know if the turbo inlet is suppost to see that high of psi. I mean it actually doesn't see boost correct? So what would be the benifit of testing it in un-real conditions.


Side note. My accessport said my afr's on the highway with cruise set were 14.6. Is this bad?

Hey guys, i guess this is the best place to ask this...

do you guys think this is a better turbo to my EJ207 than a td05 18g???

important mods are, FMIC, EWG, full TBE, 255lhp pump...

this is a street car, i dont go to the strip and im looking for response (i have the fmic because i had a FP green in my hands but changed my mind)..

thx!

Better in what sense? 18G is bigger...so more power/a higher RPM powerband, where as the VF48 will spool more quickly and make less power overall. Since it's a 207, and you can rev to 8K plus, I'd go with an 18G or even bigger to utilize it all. I just saw a TD05 20G-ish turbo on a stock Version 7 EJ207 longblock make 375whp. Spools @ 4200, and makes power through 8200. That'd be perfect.

I'd trade the FMIC for TMIC though.

Im not sure the vf48 could do it, its really a small turbo(physical size)

I'm running 12.6's with 1.8 60 foots in a somewhat heavy Saabaru with the VF48. If I launch decently I'll definitely be able to better 12.5

I was one of the lucky ones to get a VF48 from Ty. I'll have mine on soon and update with the results after the tune.

Depends on the throttle position. If I watch my AP then I see AFRs hit 20... Its normal to see that with the AP and stock sensor. Get a wideband.

Got tuned. 274whp 269tq at 17@psi on pump. Jorge said limiting factor is the 4eat and stopped it there. But it makes power til redline. And its day and night different from stock to stage 2 to now. Video and dyno graph tomorrow when we get home.

A wideband would display the same....
Closed loop wideband afr readings will display exactly what your AP reports.

What do the experts think about a VF48 + FMIC in an 08 WRX?

a) Stock fuel system
b) FMIC
c) Catted DP
d) Hard turbo inlet?
e) 5mt

I've got a new VF48 with zero miles on it and now that I'm at the crossroads of setting up my system I'm wondering about the selling the VF48 and going with an 18G instead. Then again, apparently I can send the 48 to Blouch and they can put in an 18G wheel.

So to speak for my goals, I am looking for 215 ft-lbs @ 7,000rpm as I am dissapointed with how the stock (stage 2) car falls off faster the DOW Jones above 5,000rpm. Looking for high 12's in the 1/4 mile w/o meth in a weekend fun car.

The vf48 will support 285 all day easily.

Yeah, I've seen maybe 2 dyno plots of a VF48 in 06/07 WRX's and Saabarus that show differing curves towards 7,000rpm.

Now that I have a VF48 in my hands it looked bigger in pictures. Its definately larger than the TD04 but it looks like a TD05 in terms of physical size. Maybe a little larger hot side.

I don't know... Now that I have it I'm really wondering if I should go another route. Maybe go with EWG which would mean another new DP and UP, get an 18G wheel fitted to it, or just sell it and go 18G.

I'd love to hear from guys running an VF48 swap and how it feels above 6,000rpm. I went stage 2 a week after picking up my car and while it was fun for a week or two I'm now bored with it. I just don't want to toss in a new turbo and get bored with that if you know what I mean.

Maybe I'll drop it in and if I don't like it then just sell it here on nasioc.....

I make over 95 percent of my peak power above 6k and hold it. It makes me think its all in the tuning.
