Stephen’s 2012 Mazdaspeed3 Hits the Dyno. Giant Fireball!

Today we had Stephen’s Mazdaspeed3 in from NYC to get on the rollers to finish up his tune by PD Tuning on stock fueling Via Cobb Accessport.
Car includes a bunch of quality parts but to keep it short here’s the main components.
EBTEC Built Long block
Corksport Intake / Exhaust manifolds
Corksport CST5 Turbo
Corksport 3.5” intake
Corksport 3.5” Downpipe
Corksport 3.5” Exhaust
Stephen’s car will easily make over 500hp when additional fueling is added but for now he will enjoy a very strong 384whp car that will be super fun and reliable.

Thanks again for having us Alex, had a blast!! Been following your channel since damn near day one! The shop looks STELLAR! Your hard work definitely paid off man, looking forward to your continued success and cant wait to come back!!!!

[@SpoolingUpPerformance]

Absolutely!!! I had a great day with you guys!

[@leonardorivas6496]

Hi Alex or Stephen, awesome content! I wanted to ask a question. With the set up you have, the CS intake manifold and the 3.5 in exhaust. Did you get a check engine light? The thing is I live in NC were I have to pass an emissions test and I'm trying to build my car especially now that the my timing chain failed and I have to get that replaced. Your input would be greatly appreciated!

[@corksport]

Stephen and the Spooling Team - Keep getting after it and thanks for the Love!

[@SpoolingUpPerformance]

Thanks fellas! Much more to come

[@RazoE]

Stephen is definitely deserving 🙌🏻 been a stand up guy since I've known him

[@03max6spd]

Thank you so so much man, I never win anything lol and it all just came together, perfect timing, got the car back was breaking it in and bam, free dyno. Will hooked it up for sure

[@chief5981]

Good to see you doing so good for yourself brother. ⛩️

[@CalebsCars]

I followed you back in Tennessee l was also stationed in Clarksville. Had a boosted coyote and used to run with all the car guys there. I got into the speed because I’m a ford guy and these are basically early gen eco boost engines. Currently have a speed 3 (gen 1) with a 2.5 bottom end

Let’s go!

Love the mazdadpeed content. Almost done with my speed 3, full bolt on big turbo looking to max out stock fueling and leave it be until it dies. Then new motor time.😊

[@03max6spd]

You'll enjoy it for sure, what size turbo you thinking of running?

I can't wait either man it's gonna be awhile but I'm excited to reach 500whp in this car

[@HBghost]

Question if anyone can please help… built engine on my friends speed3 .5mm overbore balance shaft delete big turbo forged internals.. LOW OIL PRESSURE AT IDLE AND AROUND 3k RPM IT GOES TO ABOUT 30-35psi … we took the engine back apart and bearings all seem perfectly fine… new oil pump and everything… does anyone else know what to check??

[@SpoolingUpPerformance]

Could be several things. First I would ask how your measuring oil pressure? Engine could have been built with loose clearances and needs thicker weight oil. Or, Oil passages never properly cleaned out after machining of engine. Is the pick up tube new?

Dang those wheels hard 🔥 what brand are they?

[@MPSFrance]

have almost same setup ^^ gen2 speed3 2010 CST5 Built engine Corksport intake manifold and throttle body 3.5 JBR intake CPE front intercooler stock fueling 3inch downpipe then 2.5 inches exhaust that limits numbers obviously But I am close to 400whp Because of E30 mix ^^ tune is made in France on versa tuner 21.5 psi of boost at 4000rpm then 24.5 at 4.5rpm, almost 25.5/26 from 5000 to 5500rpm then slowly goes back to 23 and around 9s from 60 to 120mph

[@03max6spd]

That's good stuff man!! You need to get that 3.5 inch down pipe and exhaust! It really wakes the car up!! I didn't want to mix in he stock tank, so I'm gonna hold put and get the PI kit from Corksport

[@03max6spd]

With your mix you can run a bit more boost than me😢

[@MPSFrance]

@@03max6spd yes ethanol helps getting higher values and hope that more diameter for the exhaust will help too. Oh have forgot to tell that I have a xs power V3 exhaust manifold lol. And injection duty is between 95 to 100% So power is one thing, but handling is the key element to keep the car straight on the roads with that much power on the front !

[@03max6spd]

@@MPSFrance Get rid of that Xs manifold asap, get the corksport one and as for the suspension I overhauled it years ago. I have Fortune auto 500 coilovers with swift springs, new control arms, inner and outer tie rods, adjustable endlinks, front strut bar, rear sway bar with stiffer bushings. Corksport lower tie bar, Spc camber arms, 5 sets of powerflex polyurethane bushings, the car handles like an animal.

[@MPSFrance]

@@03max6spd oh I see so your car is going straight forward and not moving too much Just have the front strut bar, rear lower strut bar in the trunk, adjustable front end links and 4 arms adjustable on the rear axle And few elements under the chassis.. but miss the anti rollbar whiteline or anything.. PU bushings and at least the antilift kit for the front.. maybe later Xs power haha I know it could crack some day but so far so good, for the price it did the job quite decently since 4 or 5 years with 350 to 400whp

i live in PA and i notice lots of these selling with blown engines. is it easy to blow these of its guys just not knowing what they are doing?

It's a combination of both, many people just don't take care of these cars. With simple maintenance they can last very long.

[@Yo_AB_Breaks]

Maintaining healthy oil maintenance goes a long way. Not full proof but I'm willing to bet most of those blown motors weren't maintained well enough for the type of driving Speed3s tend to inspire. Even healthy, these motors soak up oil.

Why does that guy hold his arms out so far from his body

[@inadad8878]

Isn't it breaking up in high rpms?

It wasn't breaking up but it was running out of fuel past 6500 rpms so we stopped there until I go PI.
