You might have already answered this elsewhere so apologies if you have already: but why not run a sequential setup instead of compound? Do you need the compound setup to achieve the boost levels at top end? If not then sequential would enable you to keep the 66mm with no consequences other than the additional of a large OR valve or two check (flapper) valves in the inlet.
and I'd imagine using Turbosmart's straight gates would give better flow for bypassing the smaller turbine than using a poppet type. I'm just spit-balling out of curiosity and exciting to see and learn from your R&D.
The simple answer is that sequential setup can't make 100PSI of boost easily and efficiently.Even if sequential setup use two different sizes turbo the boost it'll produce won't be as efficient as compound setup.(unless the mechanic and tuner that works for it doesn't know how to control the exhaust pressure and turbo speed correctly) Then you may answer me with low end torque is crucial for launching in drag race.Well yea but Compound turbo also provide some boost(not full boost) in low RPM then go full boost after the big turbo have enough exhaust pressure unlike sequential setup where both turbo need to provide the same amount of boost pressure.
Compound setup also Make the engine get higher torque (higher boost pressure) and making the engine works in lower RPM so there won't be much friction that'll make the engine produce lower power
The key difference between both of these setup is High revving vs high torque.Sequential can provide more air flow while Compound can provide more boost.again Sequential also can provide high boost but it won't be as efficient as compound.
I also forgot to mention that Compound setup could provide a little bit of boost in low RPM but if the turbo is too small than it won't be able to consume all airflow that's given by its bigger turbo(well I should say the small turbo will choke but whatever). Basically the engine RPM is determined by how big the smaller turbo is.
Please more videos please!!!!
Please more videos
Beautiful Supra and all the work done ❤, we want to see the beast at the 1/4 mile soon. More videos please .
More videos
Fantastic
Six speed BOSS
More videos!!!!!!!!!!!!!!!!!!!!!!!!!
If you read this, comment more videos and keep it going. Don’t do it if your car is slow.
