    How can I figure spool RPM's?

    Up top, you see the Turbo sizing chart? USE IT!

    7m with the most miles?

    No way! It came to life with a GT35r and a tec3 :) But that turbo was not cutting it on 3.2L of love.... so round two. ;)

    20psi at 2800 rpm's. 800rwhp. Compound turbos!

    well keep in mind though. To get 20 psi by 2800 rpm will require a smallish turbo. GT30r tops with probably a GT28r doing the low duties. GT35r will not, under any circumstance, flow that much at that RPM on the 7M. Hell i doubt it would do that on the 2jz either.

    20psi at 2800 rpm's. 800rwhp. Compound turbos!

    well if they are not bypassing the samll turbo... correct. Though from the picture they posted of the exhaust routing and the size, they should be able to bypass the small turbo at higher engine flow (measured as pressure). The problem with wastegates such as tial etc. They do not really need...

    Thermodynamics and physics are infallible. wonder when this thing reach critical velocity fo rthe first turbo......... dyno graph looks good BUT how come they only posted to 5k RPM??

    oil pressure sending unit

    That picture is the new one? Look like the OEM oil pressure sender.

    7m with the most miles?

    <-- 2004 225k miles. No rebuilds. Never a BHG as I changed HG before upping power. ;) Died in 2004. Owned the car since 1994 with 38k miles original on the clock. 2nd owner. On a thread note. Moving to general as there is nothing technical about this post.

    New dyno numbers!

    Since duane has not chimed in and a dig up for no reason. Thread is closed. Duane, if you want you can re-open or create a new one.

    MegaSquirt II Successfully Running on 7M-GTE!!! (Lots of pics and walkthrough)

    simple because that is how much the electronics probably cost! Add the software and there you go! Remember The AEM, FAST, BigEFI etc. Support is not really free ;) It is priced into the unit. Add to that the R&D which has to be priced also into the unit. Of course that is not the "retail"...

    defi gauge acting funny

    stock t-stat is 86-90c for opening. http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?Section=CO&P=8 Unless you are in sub freezing temps, the coolant should stay relatively close to the opening temp of the t-stat and increasing when the power increases.

    intercooler sprayer

    careful! remember who you are talking with... ;) How exactly do you know that the OEM filter + housing does not flow? If so when does the housing reach critical velocity or does it even allow the air to achieve critical velocity? What is the pressure delta of the OEM filter in the OEM...

    ffim available in the near future?

    Say what? How about the vent from the box? Or how about if you want to drag race. NOt happening if they have a tech. Same with Auto-x tech or SCCA. It is not a simple matter of badabing, battery installed in back. Got to actually think that whole thing through to make sure everything is kosher.

    Ohhh ohh. lol I kind of figured you knew but still.. rather be safe than sorry ;) BTW. For everyone else. If you weld the spare tire well up and remove the well from the gas tank... 21+ gallons of fuel. ;)

    Anyone seen this turbo before?

    Well then, what is the point of this thread then?? Dead thread.......

    How long have you owned yours?

    <-- 1994 I think Mike has had his longer though! :)

    IJ Gasoline is exceptional at rust inhibition. You could always seal it with done of the chemical auto restorers use. I know Eastwood company makes in tank sealants.
