FP if you're on the stock turbo. XP if you have a different turbo.

For the brackets, anything that attaches to the engine/trans/rear end/whatever I'll remove if it's not used. Example: the green brackets of death over the injectors were gone almost immediately. Any bracket that was used to hold an emissions sensor or what not has also been removed. The brakes and uprights are open, so you can remove bits there and grind on them if you wanted too.
I'll take a picture of it and weigh it tonight when I get home from work. It was a little disappointing since the stock piece is cast aluminum and the non-AC bracket is actually steel. So it wasn't nearly as much weight savings as you would think. I think it might be a little less than 2 pounds savings.

2 lbs is more than I would have thought if the non-ac is steel. I suppose I could just cut the stock piece down a bit...but as I've found in the past, drilling holes in aluminum is kind of a waste of time when it comes to weight savings

Are we gonna see any Subie's at national tour events this year?

My co-driver and I plan to go to Packwood to see how we stack up against the Hyman's GT-R and other PNW hotshoes

I'm not sure you can fix the subie handling deficits with SM rules. Unless you were to liberally interpret the inner suspension pick rule and make a small sub frame that mounted to the strut mount and the lower control arm bolts that held an upper control arm. So I wouldnt expect too many to try to show up and be competitive at national events.

I saw Kriz win in Dixie, but he was up against a bunch of Mustangs so not really a good comparo. Did well in pax though. I think Simanyi classifies as an alien. Surprised to see Berry down in fifth though!

The BMW has a strut front, it just runs a whole bunch of caster. If we made custom front arms to increase caster to 9 degrees it'd probably solve some of the camber curve issues. The GTR is heavy so I don't know if it'll ever be a top dog unless the lighter more nimble cars don't show (240, M3, Evo). I'd predict a continuation of the lighter, narrower cars winning that are well setup and in the 400-450whp range.

My GC will be sub 2800 (if I ever get an engine for it) in SM this year. If I have a running car I'll be out at Nats this year. If I have something earlier I might be in Toledo.

Found a vid of Hyman from this past weekend. Seems like he's really timid about committing to the throttle and waits a really long time to get back on the gas as well. Not that I'm god's gift to drivers, but when I'm able to notice things like that....yeah. I could see 1.5-2 seconds being gained if he trusted the car a bit more.

EDIT: Right event, wrong year. DOH! 2012 tour video. Still, will keep an eye out for video to see if there's improvement (I'm sure there is). Interesting to see the body roll as well.

From what I saw and heard of the courses at the SD tour they weren't great courses for a GTR or EVO especially the day 1 course. GTR is too big and the EVO had too much turbo lag.

Kriz did really well in Dixie on PAX, was he running SM just because there were no ASP entries? My guess is the EVOs in SM at SD were doing that. If he ran that well in SM at nationals it would easily be a top 5 car. I think his time in ASP last year would have trophied in SM but was still about 2 seconds off the 2-day winning time.

I think the Subarus have as good of a chance as anything other than Simanyi in his BMW.

I know I keep saying it but a turbo BRZ could be dominant in SM.

I think an RX8 would be significantly better. Same or better suspension as the RX7's that are putting complete seconds on SM, only a little bit more weight. Can make the same power and downforce.

A 3-rotor 20B in SM like the SSM guys run would have to weigh 3020lbs. The 13B Renesis engine is pretty much garbage for FI without a lot of work. And who wants to put an old 13B in one?

I'm not going to debate it's a better handling car, I just don't know about getting it down in weight while sticking with a rotary. Maybe if you put a turbo Miata motor in one.

I figured the engine to swap would be an ALLTHEPORTS that uses old 13b center housings and rotor seals with new 13b side housings. 6 exhaust ports for 2 rotors, and they love the boost. Or put a piston 4 cylinder turbo in it. But I would think its the need to ballast the car up from stock weight putting people off.

The FR-S/BRZ IMHO is about as close to an "easy button" car as you can find right now. You could make 350WHP/350 LB-FT at 3500 RPM+ with a turbo, easily get under the 2480lb weight limit, and run 295s all around without much effort. Very similar to the 240s that people run but they are using turbo K24 motors I believe, and have a higher minimum weight.

I didn't take a pic of the non-AC bracket but weighed it at 1lb 12oz. Anyone know what the normal alt bracket weighs?

The weight in straight SM vs SSM is the deal with why I don't think the RX8 would work well. Yes, you could easily swap/ballast it but I don't really see the advantage over a Subaru/Evo at that point. I think a turbo BRZ won't be more than a year or two off and should be interesting. It's kind of wide though, which is really it's only detriment.

In all reality, SM is one of the few classes where there are many MANY ways to skin the cat. Even for us EJ257 guys we haven't seen any low mount turbo setups to quicken the spool yet. And as far as I know my car is the lightest Subaru I've seen in SM. If I could convince the SMAC to lower the weights for AWD cars I could remove the ballast and actually be sub 2,700 lbs.

I don't have the bracket at the house right now or I'd weigh it. From memory I'd guess it was around 3 lbs though. You're right, not a lot of savings, but it is still 1ish lbs off the nose. I think you'd be better off doing the forklift alternator with custom bracket to save 6-8 lbs.

SM is certainly a hard place for a subaru to live. I don't think it has aything to do with the struts, plenty of competitive cars run struts up front.

Ok, I'll admit my stupidity yet again...

Links to or short explanation regarding using a forklift alternator instead of our normal one? What?

I dont know if there is a writeup but look around, I've heard of the forklfit alternator being used on a bunch of different cars, even in SP. I think there is an airplane one too that is slightly lighter, but like $500.

You can find a lighter weight, smaller alternator from a forklift and mount it up. I'm co-driving an FSP VW Rabbit right now that did it and it's tiny. There's a little wiring involved as things don't always plug in when you're in SM . I dug through some stuff and found the part number: powermaster 8162. Looks to be about $260 and according to my notes saves 6 lbs off the nose.

And here I thought the powermaster deal was expensive!

Default Rear seat question

Im in the process of removing the rear seat and belts and was wondering if #14 in the diagram would be covered under associated hardware?

They call the piece guard SEDAN, exhaust pipe??? is this some kind of lost in translation moment. Im removing any piece which has seat or seat belt in the description then I get to this part? Would it be unwise in terms of rigidity to remove this? Looks to me like its just there to support the seat.

Let me know what you guys think, thanks.
-Dan

Even if its not part of the seat, I wonder if you can get rid of it with update/backdate. I wonder if its there on the wagon.

Here is what the Impreza non-AC bracket looks like. After handling it, it doesn't seem to be steel but aluminum, but it's constructed much differently than the stock bracket.

It is on the wagon as well, not sure how the backdate would let you get rid of it? I belive it is just the lower seat support but the naming is throwing me off.

I always considered that the rear seat bar/brace. I always just left it in because it wasn't that obtrusive but you can probably ditch it and still be legal. It's always possible the FSM is incorrect.

I’m figuring that if I’m going to go so far as to take out the rear seat which doesn’t weigh much I may as well maximize the weight loss I can get from it and pull everything allowed.

You can UP/BD to the early impreza setup that's much more minimal. I ran without the brace for years and never had a comment (doesn't mean it's legal though). Then I got my hands on a 95 parts car to get some trim and noticed it didn't have the big bar across, just two little bars on either side so I grabbed those. That way, people can't complain about it if they wanted to protest.
