vf48 Hybrid Build 470lbs on a basemap.

actACCORDingly · 05-19-2013, 02:29 PM

I have a 05 WRX with ej205 chamber matched heads to a ej257 bottom end. The motor just had stock sti rods, acl bearings, 2009 sti crank, 2011 sti oil pump, 2.0 heads on a 2.5 bottom end, wiseco pistons, arp head studs, and the killer b oil pickup and baffle. The supporting mods consist of a perrin turbo inlet, ebay downpipe and exhaust, invidia up pipe, vf48, id1000s, walbro 450, stock headers, and a turbo xs front mount. The motor probably has about 400 miles on it now and we ran into some issues of the feed line actually corroding to the bung on the hanger. So as a temporary solution I threw some o rings in it and sat back there while the car was on the dyno and made sure it didn't leak. on the basemap e85 run the car made 314/409 on a mustang dyno (362/470 on a dynojet). Not sure how much more I'm going to make once the tune is finished (probably tuesday because i need to order a feed line from the dealer). But my friend has a 2007 STi, full bolt ons, el headers, fp red, pump gas. The car made 435/395 on a dynojet (378/343 on a mustang dyno). His graph is great, with an epic up top. I'm just curious about who do you think the victor will be from a dig/roll. I know he has the gearing and the top end and roughly 20 more hp (the gap could close more when the tune is finished). I'm hoping my immediate power, almost 100lbs more of tq, and better tune could give me the advantage.

Looks like he has closer to 70hp on you. And I'm guessing his average tq is far greater, as is his overall powerband.

On the other hand, VF's on E85 can run some really good quarters. I'd say it could be close -- and the driver mod could make the biggest difference.

It would take a miracle to overcome that deficit.

WhiteBgeye02 · 05-19-2013, 07:31 PM

how the hell does a vf48 make 410wtq on a mustang dyno with just e85? how much peak boost? timing? you sir have my attention after 3 years of tuning and not having results such as this. even on my recent 07 sti on e85

I'm more surprised at the spool.

Why? It has 2.5L displacement. Peak boost is probably in the 25-26psi area

I love that the exterior looks almost stock, besides being debadged. I bet people probably make asses of themselves trying to beat you off the line.

Yea, i was wrong he made those numbers on e85. I'm not to worried, the way my car spools up hell be playing catchup when im shifting to 4th.

No, just the driver mod

Most cars from my shop leave making those numbers. the car makes no hp but stupid amounts of tq.

the car looks 100% like an impreza. It doesnt have a hood scoop and the front mount is satin black so its hard to see. its a hardcore sleeper. and its super quiet.

Its pretty normal to see a really high torque spike like that on a VF on E85. I've gotten them up to nearly 450ft-lbs on a Mustang dyno running 25psi

Thanks

Vf turbos on e85 are torque monsters below 4k. It feels wicked. My friends hits 425 at 3500 and the car squats, its actually a little scary

WhiteBgeye02 · 05-20-2013, 11:15 PM

my vf37 made 305whp & 320 wtq 1.0 correction. 93 pump. 23 psi by 3600rpms and holds that til around 5k rpms and then starts to drop off to 16.5 at 8k rpms. the engine has a ton of timing already i hate to throw more at it on pump. e85 by weeks end and ill throw up my numbers. obv nothing as good as the OP tho.

... seems like one of those there is no replacement for displacement situations.....

congrats man. wish i had a shop closer to put a real tune on and see what the differences is between what i do and what they do every day.
