Sweet build! You should get at least 300 hp to the wheels.

[Dave D.]

Couldn't have found a better model to put it in! Similar in many ways to my build; I predict a sizeable more amount of whp, however.

[Twitch_PA]

Thanks. The old setup was an fp black and an iag stage 2 block with stock heads on e85 it made 500 whp 460 wtq so I was kinda capped with that block.

I'm looking for a 600 whp daily tune and an 800 to 850 whp shootout tune.

Theres alot more done to it than listed but I'm building a 400 sbc for my 66 nova so I'm kinda double tasking. This is the car last year. I'll post a pic after I get it back from tuning at TPG Tuning in export PA. big shoutout to them for taking care of putting in the fuel system and handling the tuning !

Say, what flares did you end up using? And what is your wheel fitment as a result?

The fender flares are 2 rear sets of Honda s2000 fender flares. I did not come up with this idea. I saw a YouTube video and figured I'd take a dive. They actually work really well. The pictures you see are wrx hubs with 20mm adapters but they fit even better now with the sti hubs and no spacers. I will post specs and the website and everything shortly.

[Twitch_PA]

Got her home today. Break in tune is making 600 whp till I put another 500 miles on it (1000 all together) then she goes back for the kill. Hit 600 whp at around 26 psi on e80 (e85 pump).

This is an awesome build! And it’s a wagon so even better

Have a graph of the break in tune?

[thesleekninja]

Love the wagon!

[subbi7]

Which clutch do you use?

[TDagen]

Looks like a competition clutch triple disk?

[Twitch_PA]

It's a P&L Comp Triple. Rated for 1000 + whp/wtq. I had a exedy twin disk but had to get rid of it b4 install because it just wouldn't hold up to the power I'm looking for. The company actually sells this clutch kit with a new slave and bracket to make it push so theres less stress with engagement.

https://www.pandlmotorsports.com/shop/pandl-products/pandl-chassis-driveline/p-l-motorsports-triple-disk-clutch-and-flywheel-kit/

Alot of Real St guys use them. I love it. Obviously has the triple jingle while the pedal is pressed down and has the little screetch while engaging but it's quiet while engaged. All my iag mounts obviously make the car sound like it has straight cut gears now but it's fun.

No graphs of the break in. Nate made 700 while testing the triple 525 setup with the radium tank then turned it down to 26 psi to make it a tame 600 for break in. I have to go back tomorrow or the next day to replace the faulty flex fuel sensor. Keeps bugging out but I'll post up mustang graphs when it's done and once I get it out to keystone for the 1/4.

[TDagen]

I imagine it might spool like the 6766 with the 2.7L. This things going to rip!

Right on, can't wait to see more. Been interested to see what the 6870 can do.

[Twitch_PA]

With the cnc"d heads and bigger valves I kept the cams at the s2 grind to try and keep a little mid range but Nate at tpg said this setup spools very well for such a big turbo on a Subaru. Its night and day from a stock location to a rotated set up but now that the only things that are stock on the car are the body, rear seats and windows I think its gonna be a rowdy one.

844 whp 658 wtq
Will post graphs when I get them. The dyno went down for a bit will tuning. This is on a mustang dyno at TPG tuning.

Thanks to my friends and family for making this dream come true. I have no sponsors and this is all built by friends and family.

[TDagen]

Congrats! Looks good!

What rpm is it being revved to/redline? Can't wait to see more.

[CEEBEE]

This is an animal!

[Twitch_PA]

I have it tuned conservatively right now at 45 psi timing wise. It revs to 8k.

First time to the track getting used to the triple disk is gonna take some time. My 60 ft is killing me and my all season tires start to lose traction around 800 feet.

11.055 at 135 mph. 1.8 60 ft. Tune #3 out of 4. 40 psi. This is a full weight wagon. No weight reduction whatsoever. Subwoofer in the back, my cmmg banshee sbr in its mount, tools ect.

Going to track tonight to try kill tune. Dont think its gonna run anything better than high 10s because I rally have to drive the car after 7 to 800 feet. Peak boost causes alot of tire spin in 3rd and 4th.

[TDagen]

Awesome!!!! Look forward to hearing about tonight.

You need some stickier tires ASAP! That's a lot of power on all seasons lol. Serious power with little traction can result in some gnarly torque steering around, which can really get pretty wild.

[JDMJNKY]

Well now, that's a beast wagon! Sick man!

[Twitch_PA]

Last nights track prep was for night of fire today. Both me and my buddy broke our front driver axles haha. And I'm on street tires. O well I'll upgrade the fronts now and maybe a set of stickies and see wat she can do.

[Twitch_PA]

Got a new set of 500 hp fronts. Should handle the power split. Upon further investigation I literally sheared my front axle straight in half. Like someone used a water jet.

Car is running amazing. Hit boost cut at 49 pounds so I am on a lower tune. Will be hitting the track tomorrow!

[CEEBEE]

This is mental!

[Twitch_PA]

This was from the other week when we thought we broke the CV.
