Goodness. How long has BBR (Brodie Brittain Racing) been trading?
I can remember taking my first new Renault 5 GT Turbo to them to work their magic. I knew I would lose the manufacturer's warranty on it but from memory, I took one out with BBR to cover any problems. I did not have any problems with it in the 5 years I owned that car. That was back in the 1980s. I guess Dave was in his late 30s then. may have been 40.
I had that car for 5 years, and as I said, never had any trouble with it. After 3 yrs I bought another new 5GT but kept that standard. Wife hated the power of the car. Not that she likes the new car either but I did warn her I was going to buy an expensive car when I retire. But I must admit, I did not expect it to make the noise it does.

I still think the supercharger mods are missing a trick.
There is no reason a supercharger can not make peak boost at the same midrange rpm as a turbo.
You can also bleed off the air pressure higher up the rpm range if desired, to match a small or large turbo efficiency maps with mechanical loss vs exhaust choke.
The boost/bleed pressure regulation on a supercharger, can be just as effective as a turbo, mass air flow wise.
Granted probably not as efficient overall.
Basically, there is no reason to have a linear increase in airflow with a supercharger. its just the way it always seems to be done.

About sound test:
1. turbo kills engine sound - WRONG. Exhaust kills it. I have old turbo car, which is loud and sound super nice. ALso Bugatti Veyron or Koenigsegg or rally cars, they are not quiet, despite they all are turbo cars.
2. Suprecharged sounds nice - That is because technically supercharged engine is still naturally aspirated engine. Exhaust side is same as naturally aspirated engine, nothing between there. Only intake air, there is air pushed in. Thats why supercharged cars sound like NA cars.

Pretty easy to tell even before I ve seen it.
If the gears are completely the same, the supercharger will go in front at the start cause he git much more power in low revs, the turbocharged one will ivertake him after a while when higher revs are needed and airpressure rises.
The N/A has a good sound and is a bit lighter, but that s it, he will loose every race.
So now let s warch and see if my mechanics logic is still working.
P. s.: 6: 09 jump start from both

So. as an American viewer, with a miata and spent many times attempting to contact bbrgti about simple info; and never get a response (as most US folks discuss how we never hear back. it's great to make a face to the name for someone in bbr. Was excited to watch this video but left me very frustrated that our simple emails never get a response let alone answers back

They all got their down falls it depends on what you like to do with your car. You dig race supercharger. You roll race turbo car, you track race and need that immediate power coming out of turns and can t be heavy, ITB s. Now nitrous has less of a down fall than most of these. Less weight, power is dependent on shot mixture. Only down fall is you need a good motor.

Is Sam not cheating with the brake tests? He is always downshifting (stick or pedal shifts- go check all the races he participated. Just make it standard by simply going hard on the pedal, I think that will show the standard performance of the brakes Be like Yannie, lose if you have to but it is about the car. #carwow carwow you should please consider this.

Man, imagine spending 10-20k on a Miata just so it's barely faster than the average Fiesta ST or i20N. The fact that this car is praised for being the greatest sports car and at 250 hp and 1100 kg and it could hardly reel in a current Golf GTI let alone a GR86 is honestly kind of sad.

10k for all of that! What a waste of money! You'd be better off spending 10k on a car thats actually better an more than likely way more horse power.
or you can buy a second hand already modified car for 10k.
basically theres just way better options than the one he's just given us

WTH, my understanding on forced induction has always been, superchargers for all the time power with no lag and Turbo for mid-high rpm with lag, never seen a supercharged car loose doing what's it's supposed to do best, low end power. Very weird!

Love ya Mat, but it would be interesting to see a race with YOU flagging, and Nick, Sam, and Yanni, racing. is that even possible?
I know, I know you should always be the one to win.
Absolutely love these races, Mat, thank you so much!

Before watching, I'd assume the turbo is fastest (but I hate them, ITBs slowest but most epic, supercharger in the middle.
Edit: Oh, the 2. 5 changes the ITB game. I'm not a fan of the stroker, but it is effective at producing speed.

That was genuinely interesting to see the same car tuned three different ways by the same company as well as the stock car for reference. Guess Nick drew the short straw on this one.
Nick's Hello Matt at the end was comedy gold.

Please swap drivers next time, during the race.
For example: after the first race Matt should have gone for the turbo, the race driver to the ITB and the owner to the supercharger and the other way around on the 3rd race

Matt, now this was a great video! Thx so much!
But i really thought the supercharged car would get quicker acceleration from down low. I mean, THAT IS what superchargers' advantage above turbos are supposed to be.

That supercharged miata had a centrifugal supercharger, which literally behaves the same as a turbocharger, so not much of a comparison. Turbo vs twin screw supercharger comparison would be better. But overall good video.

Turbo cars will always suck off the line if they don t have launch control or 2 step, something to build boost at a stand still. Same thing will roll racing without anti lag they re always slow off the hop.

BBR tuned my JDM Axela (Mazda 3 MPS) with a huge Garrett GTX3071R Gen2. It made 320 on a local road which felt disappointing. That car is currently in another garage with the engine in bits! (Not BBR's fault)

Just goes to show Aleged 262bhp think that Donor needs recalibration as it's no where near supercharged should been 2nd with Less power! Mighty car mods did similar test only using real figures

It's a centrifugal supercharger, not a blower or a whipple. Only good for top-end power, hits peak boost at redline. A Harrop blower from the land down under would be a very different story.
