5 MORE Tips to Make Your Turbo Spool Faster than Ever Before!

First

i spy Kozmic Motorsports dyno sheet

Turning revs<making power sooner, assuming you can put the power down in both cases.

I’ve also heard tubular long runner turbo manifolds kill response and give more top end. True?

Would you agree that higher compression pistons play a part as well? I feel with Mi-vec coming stock with higher compression could also tweak the results compared to a lower compression evo 8. When I went from an 8.5:1 compression piston on my evo 8 to a 10.5:1 compression piston I feel like my quartermaster triple drove so much easier (less bucking) as well as helping spool. the dyne sheet also showed an increase in spool and midrange torque.

Going stroker is simply increasing displacement hence it would spool even faster if you had a 4liter with same setup

a stock cam will spool a stock or small turbo faster but it wont spool a big turbo faster and I'm surprised you didn't say a port job and a bit of thermal management I've got decent results from these things ..

What if you increase the intake diameter but not increase the runner length? Would that increase or decrease lag?

Hello

So for a twin scroll turbo do I use a twin wastegate?

Higher dynamic compression ratio and throttle body suze can also have noticeable influence on turbo spool. Also going from manual transmission to automatic transmission moves turbo spool up to 500 rpm earlier all else being equal.

vtec is actually VVL

So, this is thought is in regards to my Cummins.

I went from 2.25” intercooling piping, to 3” intercooler piping, a 3” intercooler that was larger then factory and cleaned up the intake flow as best as I could. My turbo spooled way quicker and I built boost faster. I know this works to a point, but I need to interject.

I think there might be a difference between how fast a turbo spools and how fast it builds boost. I’m talking about the actual shaft speed of the turbo. What’s your thoughts on that?

Fast spool good.
Early torque bad.
Applying all the torque available to the wheels while the engine is turning slowly will break it.
This is the whole point of the waste gate.
Boost pressure must be delivered to the cylinders in a steady progression as crank speed increases to take advantage of Angular Momentum.
Quite a number of mechanical problems are being avoided if you do things the way the OE Engineers do them.
Early high cylinder pressure increases combustion temperature, piston to cylinder wall thrust loading, compression load on the conrod, rod bearing loads, and reduces head gasket integrity.
It is, all in all, a very stressful scenario for an engine to deal with, and it will significantly reduce engine reliability.
Far better to plan for the engine to perform at the higher end of the rev range and change your driving habits.

I agree with the final drive for sure as I have 4g63t swapped 84 Mitsubishi GSR Cordia turbo with the factory 8 speed super shift gearbox.
It has 2 final drives and has a big difference in power and torque and when that td0516g turbo gets on the gate .

Mivec turbo always make a good power

What about fmic size? Will Too big hurt spool?

you forgot compression ratio, nitrous and a Spool valve.

thanks i ll get rid 3076r and replace td05hdr16g10.5t instead of it. already excited

one thing brother

unless you max out, at the end of the straight, the torquier shorter gears will gain speed over longer gearing
