    Effects of a Thicker Metal Head Gasket on N/A 7M

    You can try and play with this: https://docs.google.com/spreadsheets/d/1iMzErRr5pl7mRbzreY4t3QuiO8mRGWlfrucfxyqjRBc/edit?usp=sharing Actually, if you use high octane content fuel, N/A CR won't hurt. C/R is 8.4 for turbos and 9.1 for N/A. I choose to have a 9.5:1 C/R for my turbo build...

    7mgte head

    Hi, This sticky thread will help you: http://www.supramania.com/forums/showthread.php?97552-Head-Gasket-thickness-selection. Head and block have to be very well finished. I had to machine my block in another shop to have a pleasant RA.

    Do you run E85? If so try to advance CPS by 2-3 °

    High compression high RPM 7M-GE build

    I didn't meant copy, just doing similar with your own design. I don't know the english verb, for doing something "inspired"/"similar to" another thing. I seen computer simulations about throttle design, barrel type was the best, butterfly type the most linear between the band, and slider type...

    From what I read, I think slide throttle is good only at WOT. Butterfly is good but barrel is even better. Don't you want to copy hasselgren barrel throttles?

    OK, So I'd like this: With this just before the port side injector: And we probably want trumpet plenum side for turbo, or no plenum for N/A: Edit, ho, look what I found:

    Thanks ;) How much were doors + shipping?

    I prefer dual stagged injectors: one after the butterfly, and another one upstream because turbo ;) (Note, because normally aspired also works :p) PS: yes gantry is awsome, but difficult with turbos ! PS: other real men use barrel buttrfly :-) https://www.youtube.com/watch?v=1aFd4LtS9LA

    Nice progress :-) I would buy with injector bungs, and one of my friends probably too. Then you would have to machine at least 3 sets :-P

    Oil Pump Priming after already Installed?

    Did you try to: - measure pressure according to the manual: - check connection between the sensor and the combination meter?

    Ola, Yep I did. They haven't all that I'm looking for. The white one is beautiful.

    E85 and CSI question.

    For almost all usual fuel, there is a balance between for BTU and octane rating. I prefer octane rating for my street car. Have a nice trip Nick ;)

    E85 and CSI question.

    I use a 3p prototype TCCS. I also run a GM flexfuel sensor read by an Arduino micro controller which give me ethanol content and temperature over a serial port. Then, I open Pi software, and change the overall injector scaling, implemented by 3p14 it allows to scale according to lex afm vs...

    E85 and CSI question.

    This is what I get, that plus flushing the tank when temperatures are in the cold start problem range.

    I'm looking for front fenders, hood, front and rear bumper, and side skirt. I see you have some aftermarket body parts also, so as we are neighbors (coutry scale), I ask ;)
