Hey everyone, First post here but have been using this forum as a information bank for a little while now.

Got to work tonight on the car,

Removed my walbro 450's. They weren't keeping up at 80+psi of fuel pressure. I have begun to install my new AEM 400's that should be able to handle the higher Fuel pressure a lot better.

I'll be welding up my vanjen this weekend, Hopefully all goes well.

Well got my fuel pumps installed and the pipes all welded up.

I'll start with the pumps, I swapped my twin walbro 450's HP pumps for twin AEM 400 pumps. All the wiring was the same, lines, fpr and more, just difference pumps, just with the key on i gained 28psi in fuel system. That should cure my pump drop off at 80+psi on fuel.

got my clamps all welded it, They arn't rock start welds by any means as I haven't welded aluminum in a while and i'm just using a eastwood 200 with wp-27fv tig troch on 110v(all I have in my garage).

Now that i'm not blowing charge pipe, MAN does it rip.

Thats got to be a blast. I used to own a DSM, no where at this level but I'll always have a love for turbo+AWD.

Well, Did a couple pulls today and it's definitly a car i gotta get used to before turning up the power or i'll hurt myself.

My 60-90mph time was 3.01 seconds, I only saw a max or 88.7% tps and you can see on the log when boost comes in hard i peddle off falling to 44.1%tps at the top.

Great build. Always happy to see something different.

One of my former students would probably have a seizure if he saw your WRX.
He's into into it big time. Even has the tattoos to prove it.:p
