    Yep, wondering what it is as well. Surprised the WRX took him from a roll though.

    exactly, if that wrx is 350hp, then the 335 is barely over stock, if that

    there is no need for that suby to have 1000cc injectors if hes only making 350... plus no uppipe or manifold for the subaru? that suby would need more work to make 350awhp on the regular 2.5 block thats in it

    Oh man, I don't know why I didn't see that. Great point, 1000cc injectors would be running at a stupid low duty cycle for 350 awhp. The stock fuel system supports over that so what would be the point? With 1000cc you can run a GT-35r and make some serious power (built motor) so I don't understand it. Great point!

    Thank you sir, to be honest I don't think the suby would be able to idle with 1000cc injectors and the stock computer... I have a few friend that haven't/ barely broke 300awhp with there wrx's with more mods than that kid..

    not true at all he is running e85 and this is a four cylinder we are talking about 850cc on his set-up on e85 would be at 90% duty cycle. so im sure he went with the 1000cc to be safe

    Damn it, that is a good point as well. Larger injectors for E85 but still pretty freaking large even then for 350 whp wouldn't you say?

    I think that n54 does not have 400whp or 3 floors of marijuana smoking

    I think this stock the n54 .....

    Qui in my town there are a few with full moddens and can not keep my pace

    even my best friend mtm rs4 b5 510hp to the crank preparation is not able to get me and the nose of the car ...

    LOTS of forum ignorance here.....Been building and tuning Subaru's for years.

    -Stock uppipe is catless on these years and fine, so is the stock manifold.

    -That TR is a base model weighs almost 200lbs less then the previous WRX models at 3112lbs.

    -That turbo is mildly better if at all then the stock sti turbo which is very small.

    -The 1000cc injectors of that brand idle fine and tune like stock on that stock ECU. They are there because the car runs E85 fuel which requires the equivalent of needing 40-45% more fuel then regular Pump gas. Stock injectors max out at about 315whp on normal pump gas with a Walbro 255.

    -E85 is the equivalent of 105 octane so alot of the power is made from boost and ignition timing.

    -With a good driver that type of setup is capable of 116-118 trap speeds in my experience of going down the strip.

    -If that 335i was stock it would have been a complete massacre (106 to 116+ car)

    Here's a stock sti with intake/exhaust and meth we did the other day:

    I guess it did 12.2@115 - weighs 300+ lbs more then the car in question here and has the $#@!ty-for-drag racing 6spd.

    ^ Well, there you have it.

    How much power would those injectors support in theory on E85?

    This may be why I was thinking something different but did the newer WRX share the STI fuel system? The reason I ask if my friend with an STI made much more than that on the stock fuel.

    IMO, 1000s should be good for 500whp at safe IDC %'s on a Subaru.

    You will get more maybe 550-575whp out of an EVO/Honda with these injectors as they can target a higher Lambda mod for mod then the Subaru.

    1600cc get to a point where you cant target 14.7 AFR at idle/cruise. The car will run 12.8 AFR or so on stock ECU at it's "leanest." Most big injector cars will do this - or you can go standalone.

    Yep, they are the same/similar flowing injectors just top feed vs side feed of 550cc~.

    If your friend made more he was on meth/race or something targeting a far leaner air fuel then pump gas. Or he was on a very favorable dyno. Click here to enlarge

    I thought so, the possibility exists he was sandbagging with the power claim? That is a bit of headroom.

    He had a race tune, C16, no meth.

    Absolutely can't be sandbagging - that turbo is completely out of breath at 350. The only reason it's making that power is probably due to the 3-4 additional degrees of ignition timing everywhere.

    I think people underestimate the weight difference in both cars, gear ratios, and incredible torque curve of a proper tuned Subaru (which will look much like the 335i). I have trouble with them in my 408whp bolt on DCT which has been 12.3@117 on oem tires and drew has shown to be 118-120 mph car with tires.

    Bingo, he can target 12ish AFR on C16 instead of the 10.6 a normal 91 tune would max out on. That should give him headroom to 360+whp.

    That would be true and I see no reason to believe he has a different turbo than claimed.

    That's weird as my friend I was referencing on a GT-30R with upgraded fuel system ran me pump to pump and it was door to door from a roll.

    That's the smallest "E85" friendly injector and most popular sold on the market. Alot of Subaru guys hate injectors swaps (major pita on the top feed cars) so they go big first with expansion for larger turbo swaps later.
