what kind of lag are we talking about on a front mount on a 06 sti... really people, is it that bad? lets use a stock car (i know... no need for a fmic) add the fmic.... how big of lag (standard fmic / nothing gigantic) my buddy was trying to compare it to his supras fmic, and suggested one would lose 1000 usable rpm of spool.
I have a vf39 and a front mount on my car. I guess I don't know what a 39 feels like with a tmic. I can't complain about lag. I think my car is fine. I guess if you wanted a ride in my car to see how different it is we can do that. Oh don't forget mine is a 2.0 also.
Why a FMIC with a stock turbo? I wouldnt go FMIC unless you get a 20G turbo or bigger. If I had to do it all over again, I would run a TMIC with a 30R. TMIC = much better spool up time.
I was thinking more of a heat soak factor... you don't think that would be an issue? I'll go for a little cruise and that thing will be nice and toasty. I am looking to upgrade the turbo in due time... nothing gigantic... just something with some extra spank.
Heat soak, naw. Maybe when you sit at a light then take off it might get a little hot, but really your not going to notice much as it cools off fast. Spend alittle time heat wrapping everything, heat coating the hotside of your turbo ect. Send bikerboy a pm, he recently did some testing with his 20G TMIC setup. Save your bumper, go tmic.
Don't listen to dream. He doesn't even work on his own car...........j/k Yeah I went to the front mount for the look more then anything. I think Russ also did a comparison and found that unless your sitting in traffic the tmic's do just as good.
ok, so what would be some good suggestions for the next mods up... have, openecu tuned stage 2, down/catback ... (had spt intake... took it out.. now it sits in a box... went back to stock box minus the snorkle... ) is it really bad to run stock box strait from the well with no tubing to the front? i'm sure i'll get hell for this.. I took the snorkle out a few days back and have been debating on motogp to connect everything up, or go back to the shortram. the last 3 things I'll stick in the beast are turbo / injectors / pump... since I still really don't know which ones I want. i'm gonna pick up an inlet sooner or later, was thinking about a hardpipe... I know it won't do tooo much / maybe help increase some spool time.
Not to sound like an ass but if your really concerned about spool time I would probably not upgrade turbos.
I would think a fp green wouldn't be too far off the spool that I have now and allow some extra boost... am I wrong?
Off of your vf39. I think you will notice a little bit of a spool difference. I guess what I am going to do to compensate that on my car when I get a 20G is to hit it with a 50 shot.
sorry you hate that site, but that site has the most info on subaru's and any modification and if you cant spend alittle time doing some research on modding your car you shouldnt mod it at all.
lets not get bitter lothar of the hill people I've spent my fair share on that site sifting through the good and bad... allllll this stuff... is why I havn't decided which turbo / injector combo to go with. so i'm looking at worth while mods to compensate the rest untill that bridge comes.
Agreed. With my BIG tmic I know I shouldn't hit it hard if I've been sitting at a light or in traffic for a long period of time. I made a mistake and didn't heat wrap everything and now I'm going back in to do it. Heat wrap, isolate the turbo from the TMIC....and you'll love the tmic sppol over the fmic. he did...and when I mentioned the idea of a fmic with my car due to intake temps he quickly explained his testing. with my 16g and tmic I reach full boost ( 20.5 or so) by 2800-2850.....I've spoke to people with the same set-up, but with a fmic and they are seeing full boost just after 3000
a tad. IIRC and I could be way off on this, but I thought a vf39 flows about 430cfm and the 16g flows 510cfm at 14.7psi again, that's just fuzzy memory
:dunno: I just want more power. Like I said in earlier posts. I will fix the spool with other parts.:biggrin:
Dude, READ. All the questions you've asked have been covered before on the two national sites, in detail. If you don't like NASIOC then use IWSTI. You'll get most the answers you need there. They even a 20g sticky.
I just wanted to point out that alot of people are neglecting to also consider that beside when the turbo starts to spool up and make power, there is also your gear ratios and track type to consider. But I realize most of the people asking this question are the guys who's drag racing their Subaru's on the street/straight. In which case you should consider having the power up in the high rev's if your goal is to reach the end of the track before the other guy. And opposite if your trying to reach the next light. LOL
I've got a 20g in my 2.0 WRX and hit full boost at about 4100 rpm with a SSAC TMIC. It's very driveable and all the bigger turbo I'll ever need in my car. I've spent enough time on my 2.0 that I will likely drive this car into the ground. I love it. Or at least throw enough mods on it to blow the engine and build a new.
How much power did you make with your set up? I would like to go for a ride in said car. Never ridden in a 20G car.
was that so hard silly gumdrops... no it was not so hard... thank you. when I asked "bla turbo spools" I want to hear I have this car in mn, and my car spools at bla rpm..." not Statistics show this is possible on bla dyno in bla state... if you have it, then answer if you don't .. don't be rude and say "SEARCH!!!!" why ask what the oranges taste like in california if you can only buy wisconsin. ps.. baked doritos... very interesting
Well my car is sick at the moment, bad gas or other mechancial issue yet to be solved...I haven't had it dynoed yet, but I was at 240whp with my VF39. The new setup is way, way faster. I've also added meth injection. So I would guess I'm in the 300whp range. When my car's healthy again, I could give a good demo.
Nice. I am at about 270 with my 39. I am going to get me an external gate, water injection, 20G, and spray.
haha...yeah, some internals work would be a thought if getting spray and meth. I am actually waiting till my engine starts to give up. Then, I will 2.5 swap with internals, cams, meth...possibly spray for race gas but then, a tranny rebuild or upgrade will be necessary as well. I don't think the 4EAT will hold up since it already has 120k on her :hsugh: ....oh yeah, and a GT30R rotated mount setup FTW!!!
well, i've only had the spray for about 3 weeks and the 20g for about 2 months, though never drop the clutch and try to shift pretty smoothly
To be honest, it's opinion based, really. I personally prefer the top mount option, as it is better for throttle response. Others like the front mount option because they a) need a bigger intercooler or b) want to look cool.
I think it really all depends on your goals. There's no question that the VF-39 doesn't require a FMIC though. That was well documented on IWSTI.
