@kamel6k / @leita0 - it might be worth pointing out that everyone here only ever talks about wheel horsepower, not flywheel horsepower like we do in Europe... From one of the other threads where leita0 posted a dyno the 365HP maybe at the fly, 300ish at the wheels...
FWIW, I'm making 300whp (350something fwhp) on a gen1 GTX2860R, external wastegate and the dinky Tial 0.52A/R exhaust housing on UK 97RON (~92 US?) fuel. 1.3bar / 230KPa boost until redline...
"We" are aware of that... Our 360 euro flywheel hp make 8.2/3 100-200 Km/h. I know for a fact that our fwhp= virtuadyno Dynojet mode whp. That's all i can assure and can't justify the differences.
@390 euro fwhp i'm on the 7.2/3 100-200 Km/h with 2 gear changes, 1100kg car + 100kg driver.
FWIW at 18psi/ 230kpa Im making 335whp on a virtual dyno thats on US 93 octane. At 22psi I make 370whp, and I just posted a video above of me doing a 40-125mph pull and thats on the 335whp setting for boost. 1.3bar from a GTX2860 is definitely more than just 300whp assuming its set up correctly.
My car does 40-120mph in 8.x seconds something. I don't have a dragy maybe I should get that.
There's no need for a dragy. Just GPS correct your speed on tunerstudio. usualy tweaking in tire diameter and you get close values. I use a dragy and is on par with my logs.
I think 10 seconds 60-125mph (100-200kph) is FAST (that was my goal with the miata), but you are all saying, that you do it in 7.x or even 4.8s?
That's crazy, all I can say...
I would LOVE to make a new thread "60-125mph" in the timeslip corner and compare setups all day. Am I stupid?

I checked my video for my 60-125 time because right now my tuning laptop died so i cant log it but with 335whp it looks like just under 8 seconds like in the 7.5-7.8 sec range for my car going from 60-125. Thats with a 6 speed and 3.909 gearing with a 7400rpm redline.

Got to mention your car weight when those numbers are calculated out.
I'm pretty sure quarter mile speed is well documented as a measure of horsepower. The eurozone just needs to figure out how many meters that is, lol.
quarter mile is 402,336meters. Which is the standard drag race length here in the Netherlands and Europe. Biggest problem is that all the drag race tracks are.. not actually tracks. Most are on old airports. so crap asphalt and even crappier organisation.

It’s major dependent on grip to make it a power measurement. Besides, you have to basically ruin your car for everything else to make it “stand a chance” on griping in the low gears, specially on a miata.
looking forward to your comparison of all these turbos!!! Hope you are gonna run 20+psi and really SEND IT. lol
I am hoping to try spinning them all in the 20-25psi range if not higher. I have FaeFloras old motor in my car, if he could not kill it, then I should not be able to either.
Well the G25-550 fits on a NA/NB with zero issues. The rear outlet is a bit shorter then the EFR so downpipe clearance should not be as much of an issue.
