[@cyclingbutterbean]

That my friend is a 550% increase in horsepower from stock. That is quite impressive for a home built motor. You done good Greg!

[@Red2l16v]

It is a 450% increase but 550% of the original power. I am a nerd sorry.

[@alessiocarlevaro6934]

@@Red2l16v yeah red his comment and was expecting 650whp, i don't get how people get it wrong

[@Jimmy_Broadbent]

I had 330 or so on a built BP4 and I thought that was too much...this must be next level! Congrats on this insane build man :)

[@cheesepizza87]

hp to weight ratio is phenomenal, excited for your track mx5 in 2022 nice to see you around yt Jimmy, congrats on an awesome 2021

Did you have the boost mapped to TPS?

[@TomsTurboGarage]

Congratulations Greg!! Excellent work on this beast!! 😳👍🏻

The man and legend himself! Hey Tom!

[@gonshik]

Ahh, Approval of Tom himself. Nice to see you around!

[@musnireggie]

Toms seal of approval!

[@cubbiefn]

Tom! Hope you're doing well! Any chance you have some new content in the works?

[@TheCarPassionChannel]

Thank you Tom! You definitely helped pave the even back from when I first got my car and was drooling over Sunflower

[@badgermetal]

Really like the relatively quiet exhaust note. Almost tricks people into thinking it's just a little miata with fat tires.

[@MsMotron]

TheCarPassionChannel: "returning mustangs to their natural habitat, the miata rear view mirror, since 2011"

[@TheCarPassionChannel]

Lmaoo

[@BeckersGarage]

I was so hyped when you got that first pull at 503hp. You're an inspiration!!

[@EliB0217]

My 99 Miata I used to own was 260 whp and torque I felt that a Miata shouldn’t even have that much so I can’t even comprehend lol .. 260 felt insane lol but fun

[@jcr8834]

Imagine 500 or more in Datsun

[@drpiv]

Simply incredible. Gives hope to all of us ancient miata owners.

[@SkyofDread]

Man I have an all stock NB, can't imagine what driving this thing would be like...

[@blackinblue11]

What a milestone. Don't even know where to start..remembering the 420hp achievement, it was so overwhelmed DRIVEWAY build. But this 523hp is beyond words, ofc it sounds insane and wants to rip the rear subframe from the body, but no bogging, no missfire, like a normal daily car. Congrats dude, you are amazing and you inspire. I'm so glad that followers could help with a few gallon of e85, it was used gloriously:) Off to grab a t-shirt now WHAT'S NEXT??:)))

[@rappit4]

You should def get an AEM 12 turn trim pot for boost control. Its P/N is: 30-2056 Its a must for high hp miatas. You can set a boost table 1 for wastegate pressure and boost table 2 for your mad table and have the trim pot blend the 2 tables in MS. 0 on the trim pot is 0% blend 12 on the trim pot is 100% blend.

[@FDB77]

I had a massive smile on my face all throughout the street pulls! You have built one hell of a monster Kreg

[@clayfranklin3513]

Absolutely ridiculous man, that thing sounds wild lol. Congrats on how far you've come it's been really cool to watch and learn.

[@efrendelgado9124]

500+ miata good job 👏 👍😎

[@1987RX7TII]

Your car makes literally double the power to the wheels as my setup (basically max stock con rods) and I couldn’t be happier for you man. Been following this journey if you’re for a few years now and it’s so great to see the insanity you can unleash. Please be safe out there man the community would lose so much if anything happened to you. Keep up the wonderful content creation.

[@MrMDGP]

You have to do a new draggy run in this beast. We all deserve it. BTW have you tried 275 tires just in the back since there is no turning it may help with traction, you can use all the traction in the world with this beast of a car.

[@pattyboi]

Awesome work, that is an insane number for any car much less a Miata ;) doing our community proud

[@nickchilds3104]

Congrats Greg, you earned it. I've been watching you for years, had two Miatas since then, and haven't even owned one in a year. I can't imagine ever not watching your videos since I'm always learning.

[@1knowsnothing1]

I can’t believe I’ve been watching your channel since before your first belt change diy! Congratulations for all your hard work and thank you for sharing your knowledge over the years! Well done! Can’t wait to see your next platform. ND, NC or If you decide to become Greg the E30 Dad I’d be okay with decision too.

[@jessereycrispin587]

And here I am with my 94 miata with 190k miles still happy it runs.

[@joro8604]

I’m happy for you. 6 years in the making, at least me watching you.

[@VaitkusMantas]

My favourite is the "what the f*** was that?!" from the cameraman LOL. I know exactly how he felt after the first pull.

[@Tom-ur7ew]

Please do a 100-200 and 60-130!! Congrats! Amazing results! 💪🏻

[@BulliKid]

Congratulations. And I love the intercooler comparison. Keep up the good work. Home built is the best! You came a long way! Must be crazy to rip the car with this power to weight!!!

[@wills_garage335]

Thank you for putting together these videos and congrats on breaking the 500, looks warp speed fast! Honestly, I've learned a ton and still reference a lot of your vids when working on my Miatas. I went BW turbo after seeing "real life" results on your vids, now I'm rebuilding a pretty similar setup: 6758 on kraken, forged, vvt, MS3 and ID1000 and so on.

[@JAGZBUILT]

Insane. I don’t even have words. I can tell it’s literally so fast that you can’t process your thoughts

[@markstorer7204]

Fantastic work Greg, I think that record will stand for a while 👏👏👏

[@UnsponsoredBuilds]

Fuck yeah just worked 12 hours and been looking forward too this more then my wife’s homemade enchiladas!!! Let’s Go!!!

GOD DAMN SON! That has to be insane. I mean from a roll, itll take down just about anything. Now go race a plaid like everybody else. Lol

[@andrewbaxter4749]

Great job Greg! Thanks for sharing all of this with us. Your channel is a "go to" for Miata enthusiasts. Congrats on a fantastic build.

[@xmanguy94]

I finally finished rebuilding my engine for the 2nd time but it's running. It's turbo'ed, obviously not like anything close to yours, but it's turbo'ed. I just wanted to say you have been an inspiration to me and made me believe in myself to doing this. My turbo project has been about 5 years in the making, doing a 1.8 swap, gathering parts for the turbo, adding the turbo, throwing a rod, swapping in another 1.8, breaking a piston, but now it is now running after about a year and a half of fixing. I just want to say thank you for everything Greg. You don't know how much my life has changed because I started this project when it was a dark time in my life. Thanks again Greg.

[@Zeb70]

Nice touch with the dyno plot journey at the end Greg! Beautifully done. Congrats!

[@Leon300idas]

Good job Greg ,hard work pays off !

[@Friendsofdonr]

I got hammered the other day for telling people my power goal. I was told "Dyno numbers are just figures, what does it trap?". The reality for me is my goal, is just that a goal. I don't plan to run it at full power for events, it's nice to know the power is there if and when I want it. 500whp in a light front wheel drive car doesn't make much sense for autoX and hill climbs with the way my power band works currently and lack of decent tires. I could care less what my 1/4 time is, but would be fun to try one of these days. NOT EVERY STRAIGHT LINE METRIC MATTERS to me, and frankly being judged solely on my trap time minimizes/disregards absolutely every accomplishment I've made elsewhere.

[@E30Eric]

I’ve never owned a Miata but I’ve been watching every video since 2014. Just begged my wife to stop watching Friends so I could watch this on the big screen! Couldn’t be more stoked for you!

[@jackjones6936]

Well done Greg, you've done your homework and put your heart and soul into that Miata. It's a beast! Any chance of a cost breakdown? I wonder how much you spent vs how much a v8 swap would cost.

Congrats Greg! Love that you kept the pop ups too.
