2016, Jan 11 - Dyno'd, Driven, Back under the knife.

We hit 518/493 whp at 28-29 psi on the mustang dyno at Infamous, which reads stock STis at 220/215'ish.

I've got it apart already again though, my GTX3576 with .63 AR hotside is a bit restrictive so I'm looking into other options. Considering a Precision 6466 and looking at Garrett options. Would like to keep the T3/4-bolt 3" housing though.

Here's a couple vids from the short period of time it was on the road during the holidays though.

Re: Deek's 08 STi - AW/BBS

ordered from: Cheam Motors, UK
cost: $285 shipped

i received the cargo mat today... i'm pretty displeased with shipping but i guess there wasn't many other options. they folded it in 1/3's and the edges are a bit warped as you can see in the pics. also, it only velcros to the rear of the back seats, and when you put the seats down it un-velcros and sides down the back of the seat.

the material is rubber, quite flimsy as you can see from the pics, but it should do the trick to keep it clean back there.

i'll try to get some better pics of it in the car once it settles and gets its edge shapes back.

OK I put more pictures of the cargo mat in the car...

Re: Deek's 08 STi - AW/BBS

Ooh, more stuff came in today - I'll post some more pics later today after I unpack and install the WeatherTech front floor liners... this is probably the last really unneccessary thing I'm doing for a while. Next is tints and clearbra.

NOTE: The actual mats are black, not beige.

Pictures went missing, post edited.

Did you have to roll your rear fenders or is it a good fit? I am thinking of picking up the dforce myself 18x9.5 and i already have 265/35/18 tires to put on it.

Re: Deek's 08 STi - AW/BBS

Today, Tom (mnym8kr) and I knocked out the following on my car;
- Group-N Engine Mounts
- Group-N Transmission Mount
- Whiteline Steering Rack Bushings
- Kartboy Shifter Bushing Combo
- Grimmspeed Air Oil Separator
- Finished the Goodridge lines install

There is significantly less slop going on under the hood and tranmission whine is quite audible in first through third, which for the moment I quite enjoy. Once at cruising speed though, additional NVH isn't detected.

I believe some forged internals are next up, I'm just too scared to do any power-making mods until I have some 'solid bits' in there. We'll see though, only time will tell.

Thanks again Tom, for your hospitality! :tup:
