There was a lot of good info in your post and it's much appreciated!
Are there any other power adders you can think of, or ways to reduce drag (pullies) that are worth it? I have seen guys post excellent results from a light wieght clutch/flywheel as well, but I don't think we'll be doing that any time soon...
She has also had her eye on a set of Enkies that are about 15-16 lbs per corner. I'm thinking those could help out a bit.
not really. you could maybe buy ricerwetdream perrin TMIC for cheap and then sell it for what you bought it for after you run.

getting those wheels would help a lot! 34lb of unsprung weight is a lot more than pulling 34lb off the car. a light weight pulley would add to that also, perrin is the lightest. im not sure on the math for 38lb unsprung but people always say this "1lb unsprung=10lb sprung." i doubt its true but hey, 38lb really is a lot.

PS, a better lighter tire could also take off another 16lb unsprung.

So you're saying the stock rims are about 24-25 lbs? This is about how much I figured they were. That's good info to know, thanks again.

we'll experiment then if you dont believe me. you go find me 1/4 times (and more important MPH) for subi's with a 18g and ill find vf52's and vf48's 1/4 times. something tells me the times wont be different. you really think a 34lb/min turbo can run the same time as a 38-39lb/min (PS blouch's 18's are 43lb/min)? lol and find me a 16g that can run, id kill that thing.

PS, a 16g can barley fill a 2.0 motor and cant break 300hp, on a 2.5L its a dead turbo which the vf52 and vf48 are not.
I hate to disappoint you but VF52s are not made of fairy dust and unicorn phallus as much as you seem to have chosen to convince yourself they are. An 18G will make more power on equal setups 100% of the time. The VF22 is still the most potent STI turbo and even that flows less than a Big 16G. And yes, the VF52 and 48 are "too small" for the 2.5L.

I wish IHI would just stop being so secretive with their flow charts so I could get you top stop feeding people bad information.

your stocks are 23.5lb, your tires are 24lb, and your pulley is 5lb. the enkies are 15.2lb, some nice, cheaper, high performance summer, sticky, light, very comfortable tires like mine (conti DW) are 20lb, and perrin pulley is 1.3lb.

even if you dont believe the "1lb unsprung equals 10lb sprung", you could at least say 1lb=2lb. so at 106lb you're already half way there to 200lb. pull the seats and trunk and you should be there. now you just need a little more power.

well i dont know about you but me and a couple of guys got some pixie dust then when we bought our cars.

cant believe i have to do this again but ok

full weight premium, heavy 18's, crappy tires, 93+meth, 3460lb total, 12.01 at 114mph vf52...

New record on vf52 - NASIOC

how bought me, lower reading dyno, 3062lb, from the tuner of air boy thats done 1000's of tests!! "Scott from thoughs readings you should do about 116mph", id guess at least 11.8 1/4

11 WRX maxing a VF52 on 93, 344hp, 382tq - NASIOC

post number 52, 12.15 at 112mph, full weight, e85, some bolt on parts

1/4 mile king of the hill .if you want your time posted post it here

as for 18g's to start off; pics dont help you much, vf48 vs td04, 18g vs td04, vf52 vs td04







lots of parts, e85, very set up drag car, 12.5 at 114mph, only 2.0l, hell i cant even find 18g's on 2.5l because it would be stupid and a waste of money

2005 Wrx: 18g 12.54 @ 114 - NASIOC

want to view post 13?? 18g, e85, only 330hp on airboy and the main OP, only 90mph in the 1/8

test and tune, 05 sti 18g td05 330 whp 342tq, 90.62 mph 1/8mile - NASIOC

crazy build, light car, e85, Blouch's big 43lb/min turbo, only 11.8 at 115mph on a hybrid 2.5l

Dyno Tune: 2.5L Hybrid / 10.5:1 / 18G / E85 (354HP/429TQ) Auto-x Build - NASIOC

dude i could do this all day. an 18g doesnt have much if anything over a stock IHI turbo

I ran 13.09 @ 104 on a stock turbo, but I think it was more luck than anything else. The 91 octane will obviously limit you, but with a power adder like meth or a higher octane gas you should be able to break it. You said you don't want to run those options so you're only real option is very heft weight reduction.
First car nope and I do believe the second car did at some point. The first car as a butt load of mods, but meth isn't one of them.
