Drivetrain RMW's "Guess what's in the box?"
I believe a comparison between s/c and T only cars is useless.
Imho in similar intake pressures always the T only cars will have
an advantage of 40-60hp. Also better fuel economy
But if some day Eaton releases TVS roots for the M45 then
it will be a nice and easy buff but not to be compared
with the car you made with the stroker.
I think a comparison is needed
you are comparing the powerband of a supercharger to the powerband of a turbo and HOW that power is applied
the supercharger is much easier to drive fast as the power is linear and your powerband is 3,000 rpms bigger
the fastest car at the track last Friday wasn't the turbo cars it was a supercharged car and by a heft margin
so how is the turbo better
Maybe just being able to turn up the boost on the fly... or turn it down... bigger turbo for more top end... certainly not better for road racing but maybe more straight line speed... just speculation jan...

If you compare a T only against a s/c car that both
have e.g. 1.6lt engine, 1.5bar and 8000rpm limit
then the difference in max bhp should be about 50+ for the T only.
But I am sure the s/c car will be much more easy to drive BUT
for me it is tottaly useless to compare. These setups are tottaly
different except that the supercharger you have a goldern rule
to follow in order to have balance between s/c efficiency and engine load.
Similar with T only, were you can fit bigger turbos but you destroy
the power curve.
But for me the biggest problem on daily driven cars with s/c car upgraded
to make over 300whp from 1.6 lt is that you cant have
the option of low and high boost which is very helpfull in daily cars.
I believe in a track it is possible to see a 250 n/a car run faster than
a 280s/c car and both to be faster than a 330Tonly car.
thats why I say the driver+owner must know all of these so it is useless
to compare.

s/c: could be faster in cornerning but not on the drag.
I cant understand why you try to compare them!
and 2lt cars we see a lot of them from the JDM market
such as s2000 but these have massive issues when they
reach 330+whp... imagine with the little mini what will happen.
anyways...

probably because you are trying to compare them
you brought up the differences so now you have comparisons
I have tested the 2.0L over 600hp on my turbo car.....
any questions?

Can you post the dyno sheet up

So you used a turbo to make power
I didnt say the 2.0lt cant hold power....
I said a s/c car has some limits in power and effectiveness.
But I am not COMPARING I am just noticing the differences that
even a blind driver should be aware.
You seem surprised? Why?
the turbo is a terrible way to put power to the ground effectively on a fwd car, all it takes is one look at the tq curve to figure that out
drag racing yes..... totally different story
I know I have driven them
Also WHAT are limits with a supercharger........have you tested the TVS?
What blind drivers do you know who are driving?
