Under boost I doubt those 90 degree bends make much difference....Jerome said:I agree with you Smoke except for one thing. Look up at my post about the silicone 90's.
True but it has to change directions and that sharp bend is not good. Same reason why you want straight shots into the intake ports and into the combustion chamber. But that is also about fuel fallout and such...MYDRMKR said:Well.... I do not have my old physics book to reference.... and I may be wrong... but once you build up the "compression" of the intake system............?
Those 90 degree bends on on the INLET OF THE COMRESSOR side of the turbocharger. The bend is not on the turbine side nor is it on the compressor outlet side. One bend on the inlet side have minimal effect on the flow dynamics especially when it bends right into the compressor wheel. Do the Reynolds numbers and the flow calculations by adding one bend with a constant radius into an unpressurised tube....not a big difference. The system looks like pure mechanical art. Too bad the vette has a plastic intake manifold, add the lingenfelter polished aluminum piece and WOW!Jerome said:Under boost is where they would make the biggest difference. Any time you have air change direction it will cause a restriction. The 90 is one big one.
I have seen 90's glow red hot in an exhaust system on headers, and they were much further downstream then the smooth bends that were not red. The reason, one big restriction. Now this won't heat up, it just will cause a "flow jamb".
Long smooth tapers is what you want and need. That is a great set-up except for that.
I will look for my old physics books and double check this. I could be wrong but I doubt it.
Nice to look at - not well designed. The turbo's are small and have 90 degree bends both on exhaust exit and air intake - that will add excess heat and restrict power. The small turbos may be good for 800hp and will spool quickly due to the nice headers getting a straight shot - but it could have been a lot better. There was room. The end result may still be very good however - turbos are forgiving little critters these days with programmable tuning etc.BASH said:
