    Exhaust manifold cracking, can ceramics, other coatings, or AI help?

    Perhaps time for a Inconel header Und honkin single? I have used Swaintech coatings on everything that sees fire in my top turbo builds for years(does wonders for BSFC). But the thing that prevents a plasma applied exhaust coating like whitelightnin from being applied to the inside of a...

    Using HFC-134A to directly cool intercooler core. Dangers?

    One nice thing about it though is that it's gaseous. In the event of an accident it will dissapate into the atmosphere. Gasoline will make a nice puddle underyou and burn. So long as the propane doesnt ignite inside the car like afuel bomb...

    Fundamental explanation for different torque curve SI-CI

    faster flame propagation would be the biggest hurdle. SI fuels propagate combustion much faster thn diesels.

    Using HFC-134A to directly cool intercooler core. Dangers?

    Oh I forgot another important constraint of this engineering exercise: It's mid-engine.

    Using HFC-134A to directly cool intercooler core. Dangers?

    It's the duty cycle, Keith. In a street/strip environment I drive around removing tons of heat from the aluminum mass. opportunity to floor it presents itself,heats up core a bit. repeat. All intercooler systems operate with peak efficincy as a heat exchanger. If your intercooler actually...

    Using HFC-134A to directly cool intercooler core. Dangers?

    Greg, you have a wonderful brain. I never considered Lpg. I'll have to dig up a phase chart for it to see what pressures will be involved. Although I ve never looked at it after a good heat soak, highside/lowside pressure is well below 200 psi in every auto system Ive worked on. They seem to...

    Using HFC-134A to directly cool intercooler core. Dangers?

    I have been using the "ford method" only ford uses the bypass coming out of the main evap core to chill their liquid. I have been setting them up to run with Dual Evaporators. one for th eoccupants (me) and one to chill the watertank for the intercooler. So when I got done building this billet...

    Using HFC-134A to directly cool intercooler core. Dangers?

    Actually pre-nozzle it's 325psi, post discharge orifice (in the core) it's less than 60psi so my 200 psi test does mean "squat" as it were. But the dangers of combustability are the concern here. Thankyou for your replies, it's why I asked before doing. Hydrogen flouride doesnt sound...

    Using HFC-134A to directly cool intercooler core. Dangers?

    Who can tell me definitivly about potential dangers involved with HFC-134A seeping into the engine and being combusted? The Intercooler I have constructed is made from a bar/plate liquid/air cores from garrett. It is inside the manifold plenum and used as a diffuser/flow straightener. It's...
