I just can’t stop watching Grep’s videos honestly

[@SwedenVIrre]

I know, Crepes videos are the best!

526 HP is INSANE. This Miata must feel like your driving a rocket ship now.

[@sparkie5571]

[@R03333]

It literally makes the peak power and torque of my old Turbo Mx5... but at like 3500 RPM

[@Grumpini]

This thing could literally take on a Huracan on the highway. About 12% better power to weight ratio.

[@tomhunter91]

Always a good day when Craig posts a video

[@MJPilote]

That really shows how much things have changed in a decade and a half. Turbo technology has come huge leaps forward, 500whp from 1.9l with such a broad power band and 12:1 compression. Very nice build!

[@wual.]

It’s definitely got 600 in it. I’m excited to see it happen once you get bored 🙃

[@TheCarPassionChannel]

I don't think I'll be making the jump to the size of turbo that would require. Unless Borg Warner slides into my DM's

[@wual.]

The turbo doesn’t seem to be at its limits? Is it “already” over spinning? It really looks like it wants to make more! I mean, to be fair you were pushing the limits with the last engine, so main caps being stronger solely wouldn’t add horse power (I am aware there’s much more). I could be totally wrong, as this isn’t my car, and my miata is only making 433 to the wheels. Plus you’re miata father, so what you say goes, my liege.

[@R03333]

​@@wual. "ONLY 433 to the wheels"

7:48 CONGRATS! You have taught me so much over the years and you made that happen. I can't wait to pull out my 99 vvt to actually build it out. This is peak DIY badass 500hp driveway built reliable power.

[@TheOnlyToblin]

Solid build. I'm impressed, Greg. Well done :)

[@raviolitrail]

Hopefully the billet caps do the trick this time. Loved the puppy footage at the end ❤

I knowwwww I saw that hahaha

[@krisoftebro9781]

Oh man. I wish you could see all the smiles on the faces of people watching your video. Amazing!

[@ayyds]

Greg your badass so interesting and informative. Really putting in the work to find out what’s possible and share it with everyone with great apples to apples comparisons, this is so helpful to anyone who tunes. Enjoy those ponies man your earned this.

What a wild engine setup! You always make me wanna slap a turbo on my old BP! Not sure how much i trust it as it is but maybe someday haha. That thing has got to be fast! Can’t wait to see/ hear some pulls from it!

Great build Greg. Awsome insperation. Your content is always very educational for the miata comunity

[@DarrellParks]

I got to say, your dedication is on point. It takes so much research, time and money to get to this level. So proud of all the hard work you are doing with this channel. It's near "lightning in a bottle" to get these numbers on the Miata platform. I couldn't get close to this with my build.

[@kentworch]

Awesome build, awesome Dyno day. My car just has the 100% stock naturally aspirated BP 1.8 engine, and it's been very reliable and long lasting. Mine is still running with nearly 400,000 miles, but it is truly amazing to see how much power you've gotten out of yours as well as the passionate work you put in the make it happen. Awesome builds and awesome video. Can't wait to see you blow the doors off a mustang at the track because they underestimated that beast. You rock 🤘🤘🤘🤘

Good stuff Clegh!

[@Gabtoks]

Thank you for the great video once again ! Can't wait to get my car out of winter storage and play with it. You're the reason I went turbo with a megasquirt on my NA. Next project is to install 36-2 crank trigger wheel, bigger intercooler and cleaning of the map on the dyno. Again, all the fun is because of you and your channel that gave me the confidence for this project. 😎😎😎

Wow. What an epic weapon 🛠👌🏼❤️ From the good old days of broke-n-boosted to the 500whp beast! The journey to this tuning level has been a proper rollercoaster Greg, loved being along for the ride and learned a ton from you.. so thank you for all the fantastic informative content 🙏🏼 I think many would agree you’ve more than earned some quality time to enjoy the car.

[@FastRust]

Well done Greg! The world needs people like you - putting everything on the line in the name of science. Awesome result.

[@ftovr2957]

Love this data-driven approach. I even dyno'd my bone stock 2.0L Protege because I wanted to know what each mod afterwards was actually worth. Made a mighty 84HP. Good header and an intake brought it up to 105HP though, and my second header was almost twice as good as the first. 500HP is a little beyond comprehension 😅

[@victorsanjurjo4666]

[@martinrodger9565]

This man deserves this positive dyno session and results. Hard work and tons of gifts to viewers. The website blogs and mega build page are also great work and gifts. Now where is that optimised VVT map shown? 😂

[@martinrodger9565]

Also, did you monitor turbo speed for your record run comparisons? Internet science states your larger displacement may be pushing your exhaust side further for same hp, but your C/R is helping your compressor efficiency. Turbo speed should show you where you are on comp map. May only need a one size increase on exhaust A/R to see sudden hp bump if comp map good. Then you can torch your low comp record with same response. OR. Just enjoy it for a period!

[@BrycenKauai]

That little EFR is a monster!

[@Nandwar213]

Great work grig

[@TurbineResearch]

On your 512whp run your wide band gauge was showing 12.2 AFR . IMHO that doesn't leave a lot of room for error being that cylinder to cylinder AFR can spread 10-15% on even well setup cars. Drown that thing in fuel until it coughs then back it off a touch. Just my opinion on giving yourself some margin of safety 🦺. Love your videos keep it up :)

[@gm5383]

Greg a "fun street" mx5 is a TD04 turbo'd 200whp car, what you have there is some insane exoitic killing monster lol

The last thing i learned in this video is that you’re so focussed on your awesome car you forgot to mow the lawn 😂 In all seriousness, congrats on making this thing more amazing and besting your own records!

[@alltheboost5363]

I have a low.... like really low cp engine. Stock was 7.4 to 1, and now it is about 8 to 1. Milled ahead and went with a super thin head gasket. I personally like big boost numbers but also love a super Snappy responsive engine. I'm working with an old Datsun engine 2.8l l28et. I've done a couple of different engines, 9.5 to 1 cp and 8.8 to 1. You really can't tell the difference between the 8.8 and 9.5 cp engines. If I was going to give advice to anybody, I would tell him to go with as low of compression as you can to get to your goal.

[@christophergoris9923]

Did you notice a change in overall sound of the build now that your high compression? I’ve heard once you do a hc build it sounds like an absolute monster

[@TheMapleDaily]

Inspiring! I'm doing something a little similar to my other project car! I should make 300-400 on a low boost tune while I have a high boost tune for 500-600

[@chuck889]

that miata is sick, bro makes me miss mine.

hell yeah bro that is awesome and prolly way more reliable to but good to see ole red back going bro and them numbers my god that was gnar ... anyways peace and love Miata dad keep it rad stay safe and build on... ps now eager to see whats gonna happen with 2sj ... much love and respect bro .. l8z

[@t32prod.98]

[@iamtheleuz]

Congratulations to the whole building and filming crew! 😂

[@x808drifter]

Love the old school thinking of "If you add boost you have to lower compression." More proof that if you do it right you can up the compression on older engines.

[@38tech]

Omfg. Nice. Drive it out to the east coast!!!! Matg is calling!!!

[@KrausesCars]

I always love this I feel like I’m the only person when they say they want a certain number once I hit that number call it and clean up the tune irw scenario and go on with my life. Unlike most my buddies 😂 i don’t got the money to be “fast” unless a sponsor comes out the wood works.

[@cptherr3309]

Amazing ^^

[@yepnope2195]

According to an online boost-to-compression calculator the effective compression ratio of the new engine is 33.71:1 (26.6psi@12:1). As compared to the old setup with 28.41:1 effective compression (31.7psi@9:1). So assuming this calculator isn't whack, you're able to get about 15% more air into each stroke at sea level. Neat. Expressed another way the old engine would need to be running about 40psi@9:1 to get the same amount of air into it. Super neat... or my math is bad and I need to repeat class 😁

[@lilmike2710]

Damn I bruised my fingers from smashing that play button

[@grubinski]

Cool video, cool channel. I like my LS3, but I like your turbo, too. 🙂 I like to do road trips in mine, on two lane roads out in the middle of nowhere, so I'm glad it'll run on 92 rather than E85. That's the only downside I can see to your high CR approach.

[@TheCarPassionChannel]

Thank you for being an LS guy who doesn't just say I'm stupid for not LS swapping, you are a rare breed. Both approaches certainly have their appeal, and I absolutely love LS Miatas too.

[@90RECON94]

Very Nice , One of the best videos Ive seen in along while . I would bet that those piston rings will wear out sooner then the low compression engine though . Had an AE86 Corolla with 427 HP Power to weight was a blast . I could beat the R32 GTR by third gear easily . Cheers
