Thanks! What are you referring to that is so "insane"? Thanks! Thanks! And yes, stock sleeves. What LS swapped Subaru have you seen that runs faster? As far as I know this is the first Subaru in the 9's at Rock Falls, first MN Subaru in the 9's since Dipp and Bullet in 2012, and the 2nd quickest Subaru from MN (behind Dipp). Nationwide and worldwide there are definitely some of quicker Subaru's and if everyone in MN gets their car together there should be a handful faster than this.
Nice!! According to the interwebx these motors instantly self destruct at 500whp! *knock on wood* I'm not trying to jinx you (if you're superstitious) but I'm curious how long the short block would hold up. Are those just off the shelf CP pistons? No coatings?
Now that I think of it, there are really none that are faster than your WRX. Apologies. IIRC, there was an LS Swapped WRX here in MN that ran low 10s though.
I think the standard ARP's are more of a liability than the stock sleeves, but either of them could go. Pistons are nothing special. Where were the 1/4 mile times posted for the LS WRX?
I was referring to RBB, though he hasn't put the 1/4 times down, his 1/8 mile was insane. Actually the 1/4 was an excellent time too all things considered.. I'm certainly not trying to knock your car Ben, you have put together in a short time a car that I could only dream of.
Here are some shots of my car from DCTC from other photographers that were at the event. I was just there helping out and I did a couple slow laps around with my daughter in the backseat. Here are a couple shots of me rigging Slomander's GTX35R WRX: Here's the final shot:
Is that really how the rolling shots are done? That's pretty crazy, they seem like you'd be moving at a higher rate of speed than that. Looks pretty wicked with no one behind the wheel!
it looks like the light was dropping off and the aperture is probably something like f16 so you could be shooting with shutter of ~1+s and it'll probably give you enough motion in the wheels even if you're pushing it by hand.
Yes, the car is pushed at low speed with a long exposure time. I typically use 4 seconds. I have a 10 stop ND filter that I used for some of the rollers and I also did some with just the CPL (and high aperture), but I don't remember which one I used for the final image. EDIT: I just looked at the image data. This shot was with the 10 stop ND filter installed (and the CPL). Without the really dark filters it has to be pretty late in the day to get the 4 second shutter speeds. I believe it was still too bright when I took this image.
Here are some of the shots I took. My car: A few other shots. More can be found here. http://mnsubaru.com/threads/6-5-2015-nf-performance-driving-school-at-dctc.49330/
Over the weekend I did a few updates to my car: Installed an IAT sensor in my end tank Replaced fuel filter Cleaned the bugs off my FMIC Installed Aluminati solid mounts (motor, trans, pitch stop) 3rd gear pull (~90mph) goes up 2°. 4th gear pull (~130mph) goes up 10°. No photo of the transmission mount because it's not coated yet. Torque Solutions mounts that came out.
Nope, just the fact that ambient air temp is basically the same as the post IC temp when the pull starts. I don't know if the turbo starts blowing hot air at high boost. I'm sure it does to an extent, but I don't have the data.
That's exactly what I'm wondering... whether it would be beneficial to turn the boost down at higher gears. Which nets more power, same PSI and 10deg IAT increase or lower PSI and 0-3deg IAT increase. The difference is probably marginal and yes I'm a little bit idle in work right now.
That would be interesting data, but the bottom line is the power and the dyno was still showing more power as boost increased. I still think this turbo has at least a couple more psi in it before it becomes so horribly inefficient that power would actually decrease with increased boost pressure.
Yesterday NF dropped a new clutch disc in for me. Last time at the track I did around 10 bunouts + launches (on slicks) and then on one of my passes the clutch wouldn't disengage after I got off the line. I got it out of 1st, but it wouldn't go into 2nd. I eventually got the clutch to disengage and got it back in gear but it was really rough whenever releasing the clutch. Especially from a stop in 1st. I drove the car home and after a few more starts it smoothed out mostly. NF had experienced a similar occurrence with their Speeding Bullet STI a few years ago and suspected the clutch had welded itself and then eventually pulled apart chunks of the disc. Based on this, the decision was made to replace my disc before the Proving Grounds event this weekend. Once the clutch came out, it was confirmed that mine had experienced the exact same thing as the Speeding Bullet. The disc had chunks missing and he pressure plate had parts of the disc embedded into it. The flywheel was replace with a freshly resurfaced one, the disc was replaced with a new ACT 4 puck solid disc, and the pilot bearing and throw out bearing were also replaced. Also drained fluid and refilled. The chunks were removed from the pressure plate and it was re-installed. It has some obvious hot spots but no major cracking or warping and should be fine to use. I'm hoping this will get me through this season and then I'll probably end up with one of the triple disc clutches next year.
Have you put any thought into coating (or even painting) your intercooler black? It apparently makes a measurable difference in air temps.
I believe a thermal dispersant coating would help with heat transfer. There has been plenty of testing to show this. Any old paint would probably just create an insulating layer (because bare aluminum is pretty good at heat transfer), and that's not what I want. I have thought about doing it. Just haven't made it a priority at this point. Probably someday though.
Driving it. This car has never been on a trailer. If it breaks I'll just have to get it towed back. Haha.
Huge lines to get in yesterday. Took me two hours at the gate. Made some passes on the Mickey Thompson drag radials and no boost off the line. Got it down to 10.2 but then 60' didn't seem to be improving so I quit for the day. Hopefully it dries out today and I get make some passes with boost off the line and maybe the top end bumped up a little. DA is quite a bit higher this weekend than when I was at Rock Falls.
I ended up doing 10 passes throughout the weekend and then got booted for no cage during eliminations. No one in my class (62mm turbo) was running faster than about 11 flat. My best pass was 10.1 @ 140mph. I picked up a few mph by not shifting into 5th. I couldn't hook well enough on the street tires to do 9's. I was consistently 10.2 or 10.3. I will try to get some video up from the 1/4 mile runs soon. For now I have a video from roll racing against a couple EVO's. One is a custom PTE 66mm and the other is a forward facing PTE 6466. Both were at around mid-30's for boost (according to their owners). Runs are from 40mph to about 150mph. I drove the car to and from the track (2hrs each way) and didn't have any issues throughout the weekend. In the last month the car has seen about twenty low 10 second passes as well as over 1,000 miles on the street. I hope it keeps it up, but I'm sure something will fail eventually as it's being pushed very hard for what the setup is.
Awesome, thanks for the update! Any reason why you didn't bring the full drag slicks? Glad to hear it is running so reliably too, hopefully it keeps up for the whole season.
I had the slicks, but I was trying to stay within the RSU (62mm class) which didn't allow slicks for AWD cars. But then I got booted for no cage anyways.
I feel I've somewhat reached the limits of this turbo, so I'm thinking of going bigger. I've listed my turbo FS if anyone is interested. http://mnsubaru.com/threads/fs-precision-6266-turbo.49407/
Lol I knew it wouldn't be too long before it was time to upgrade! GLWS Ben! Any idea what turbo you're thinking of going with next? 6266 Gen 2?!
Man, walking evo's with several mm bigger turbos is quite the accomplishment! Usually their VE and short manifolds outperform subies but that fog light setup clearly works! 6870 next? Will you rebuild the motor stronger if it lasts the season? Or try to wait it out until something goes? Great results!
**(chanting)** compound compound compound You should cage it this winter so you don't just get kicked out for putting your foot down...
Not planning on it now. Still keeping it my daily driver for the summer. 6870 is a bigger housing so it would require fab work, so probably just a 6466 or 6766. I'm hoping to do a stronger motor in the off season. Crossing my fingers that this one will last that long.

Nice work Ben and nice shifting! Out of curiosity, what size compressor was on the 40R and what tires was he running? Also out of curiosity, do you know what Brian and Johnny ran? I don't see results posted yet...
Fobia's car is this one, but now with an auto installed in it. http://mnsubaru.com/threads/fs-2004-aspen-white-sti.44267/ It's a 4088, so that's a 63.5mm compressor. Seemed a bit down on power only trapping mid/low 120's. Johnny's car dropped a sleeve and his wheels don't fit so it didn't come at all. Brian's car bogged on the line and missed 3rd a couple times and then quit. No full passes.
Dang, well your car proves that you don't need sleeves, fancy setup, etc to hit low 10's, high 9's! And reliably at that.
