Wow that's amazing 150rwhp more and only 108 more pounds and it will not catch the bmw till 160. That breaks the laws of physics, got hand it to those germans.
I mean 27 percent more hp and only 3 percent weight penalty and it still can't catch it.

Can't wait to see A90 on the street against a BRZ

Probably has to do with modern traction control, 6 useable auto gears vs 5 usable manual gears, and maybe a little aerodynamic.

Curious how a K24 swapped turbo BRZ would do... lol.

And one has auto pilot and the other needs an old school experienced driver.

Should do pretty well considering its using 705 gs of air
Which susposed to equal 750rwhp but I have no idea if it has that. Flat foot shifts are super fast.

Have you driven anything running high boost (30+ psi) and significant intercooling before? It's not about how quick you shift. Pressure has to be rebuilt. Alternatively, you can just live with destroying turbos regularly and/or blowing off charge pipes (and by default losing the pull).

My supra does 60-130 in low 7's. The BRZ does 60-130 mid 15's.

I'd guess the BRZ would need to be north of 600whp with a corresponding transmission, driveshaft, differential, and axles, along with drag radials, just to be even with the Supra.

Even then, those would be very abusive shifts, anti-lag, etc.

2. Which is the better value for money in your opinion? It sounds like youíve put a bit of money into the BRZ. Is it worth it for the performance gains or are you better off going with a factory solution like the Supra?
1. I'd sell the BRZ; the Supra's ceiling is simply higher for a street car. At an extreme unlimited budget level, the BRZ's ceiling is higher.

2. The Supra is a better value, even at more than 2x the price, if and only if you plan on modding it. 600+hp with less than $2000 put in is very real with the Supra.

I have went 0 to 130mph in 5.3 seconds in the 1/8 mile.

Sounds like you already know the advantages of an auto vs manual then!

I was talking more about 550hp against 700hp and on the street.

With the 75mm turbo I didn't notice any boost drop while flat foot shifts.

Try turning off other channels so you can get your polling rate up, and you'll see the drops.

Compare MAF vs MAP readings to validate actual flow.

That would translate to roughly 8.4 at 160 in the 1/4

Light years faster than the fastest A90's out there.

Maf is maxed out at 14lbs 3 inch with wrx sensor.
The new bb 80mm turbo is running 20psi. The gt42 74 bb was running 21 and the gt42 with journal bearings was 23lbs. This was with the waste gates unchanged kind of weird.

600HP sounds great. Cruising at 60 then drop the hammer. How long until the boost kicks in, yo? How long until the acceleration hits hard? A second? Downshift, revs build, boost builds, then blam?
