    What turbo?

    personally, i think the t25's are great turbos for daily driven street cars. my old nissan 1.6L had a gt25 on it and the response was great.....almost instant torque :) you may also look into using a larger turbine though, some of garretts turbine maps can be found here...

    Fuel tank baffles

    on my street car ('91 nissan sentra), i added a stainless steel sump to the original fuel tank. i used a hole saw to drill holes in the bottom of the tank. then i tig'd the sump to the tank so that it surrounded the holes. my reasoning for the holes, is that they act as a baffle of sorts. there...

    Propane conversion

    try looking into LP-EFI or propane electronic fuel injection conversions....this is the more expensive route, but will give better performance than the propane "carb" conversion kits. some info http://www.ccities.doe.gov/conference/palm/pdfs/petrich_biphase.pdf javier...

    Anodizing AL....thermal conductivity?

    interesting, thanks for the replies. the reason for the anodizing is for more of a "sleeper" look. here is an example heat exchanger guts javier http://www.full-race.com

    Anodizing AL....thermal conductivity?

    as the topic states, im interested in how anodizing AL effects its thermal properties. the application in mind is a front mount intercooler or heat exchanger used on high performance automotive applications. does the anodization reduce the thermal conductivity? does it change for different...

    Turbine Housing TIG welding filler material ?

    hi everyone. does anyone know what filler rod to use when welding a cast iron turbocharger housing to a 1018 cold rolled v-band flange? does the housing need to be pre-heated before it is welded? here's an example thanks javier Custom Turbo Applications http://www.full-race.com

    Mobile welding machines

    welders that run off batteries? sounds interesting. i use a miller maxstar 200sd (inverter TIG). FWIW, it only weighs about 35lbs and is extremely portable. javier Custom Turbo Applications http://www.full-race.com

    Cold worked SS corrosion resistance.

    if a 304L, 321, or 347 ss pipe is mandrel bent/cold worked, then is it more susceptible to corrosion and the associated cracking at elevated temperatures? the part in question is a 321 tight radius mandrel bent tube used on an automobile exhaust. its a turbocharger exhaust were high...

    Turbo/supercharged Volumetric Efficiency

    is greater than 100% possible? the eq's i have found are: VE=2*(mass flow rate_AIR+mass flow rate_FUEL)/(intake density*displacement volume*engine speed) or VE=1-(exhaust pressure/intake pressure-1)/(ideal gas specific heat ratio*(compression ratio -1)) i believe these eq's are for NA...

    Spraying CO2 onto intercooler

    has anyone ever tried spraying CO2 onto an intercooler? similar to this idea http://www.nitrousexpress.com/productdisplay.php?sku=5183&hdwt=31101&loc=101&dealer= if anyone has done this, do u have data, such as charge air temps after the IC. javier Custom Turbo Applications...

    Literarure recommendations

    just curious what everyone recommends for welding handbook and or references. im planning on bending and TIGing a cage for my car in the near future out of 4130 and would like to do a little research about the pre and post welding processes, filler material, etc. thanks javier Custom Turbo...
