SPOILERS if you haven't seen part3.
I love how people preach "but my supercharger gets all the usable powerband!" And then a turbocharger has much more power through the entire rev range

Kinda surprised with the HP numbers they got. But my first guess was that it's due to conservative timing.

im loling over here when the disappointed SC guy is talking about the feel of lag.

Don't you guys understand the supercharger is better from 2000 to 2800 rpms, so that must mean it is the best.

I'm dying at the belt slip issues.

Too bad they don't know the difference between turbo lag and boost threshold......

the dyno doesnt suggest that.

A common Aussie joke when talking about a build someone saw online is as follows:

"Lol, 400 american horsepower, amirite?"

Your dynos read way higher than ours do.


The bottom end torque improvement of the blower is <2hp, and due to leaner mixtures. I already had this talk with the boys.

Anyways I asked marty to film the cars side by side, doing a rolling start low rpm drag race so we can see if the blower car EVER at any stage can get ahead of the turbo.

I bet no.

A centripital supercharger is a very different beast than a positive displacement one. The two cars behave exactly how I thought (and we all knew) they would. I am curious what it would look like with an MP62 though.

My M45 makes 5psi at 1500rpm if I feel like ruining my clutch. But it's a street car and I wanted the down low torque for climbing hills without having to shift out of 5th. For a track only car? Turbo is way faster and mote fun (at the same boost level).

I thought that acceleration plot they posted already pretty much showed what you're trying to get him to do: the tc car accelerates faster, at every point in the rpm range (you can see the two speed graphs on the bottom right I think)

I'd love to submit my supercharged example to be a part of this comparison.

They used the wrong blower....and a MP62 isn't the "right" one either.

not so shitty.

At least it is a more traditional positive displacement type rather than a rotrex which will only ever make top end.

And yeah, an MP62 is small compared to yours....

You should compare it to a 1.6 with a sr20 t25.
that would make the comparison fair.

Braineack

iTrader: (62)

and then ban everyone who says the 1.6L isnt that bad?

Yes. And disrespec deir famiry

Am I the only one surprised by the dyno number for the stock red car (before turbo). Shouldn't it have been higher than that, with the Haltech ECU? Don't most VVT NA motors put down 10-20 more hp than that?

A dyno is just a tool. It can read high, it can read low, all that matters is the difference between baseline and final plots.

So yes, you are the only one.

if the dig on TC cars is the turbo lag I'd like to see a 3rd gear pull side by side starting at 1000 rpm.

Heck, do it in every gear.

According to dann ^^ their dynos spin backwards and make lower HP than US dynos

I was expecting the same, and this was still shown even with the turbo added. No mention if vvt was touched
