Wanted to see 500 WHP Mazdas? HiBoost Mazda 3 makes 496 at 20 psi

[HiBoost TS]

We managed to make a 3.5 MAF sensor housing to test the car at more boost. Well the results are great. 496 WHP out of the 2.3 duractec motor with Gt35R Ball bearing turbo. It is laggier than the IHI, but, WOW it flows.

I was looking for 450 whp, but I was surprised myself. I wanted to boost 24 psi but right at 20 psi the Maf sensor was throwing me again into limp mode. I will make a 3.75 ID MAF sensor housing to try to make it above 500. This was on 3 inch exhaust, Haltech F10X ECU, 96 lb/hr ibjectors, pauter rods and wiseco 8.5 to 1 CR. Head is still stock but valves, springs and retainers are on my way.

I am also running our new manifold with external wastegate port and Garrett/IHI flange.

Here is the Dyno sheet..

Picture of turbo in engine...

And Video...

Holy WHP batman. Great job juan.

 

[InFeXIoN]

well congrats thats pretty impresive.

i understand making big hp for advertising purposes but that powerband is almost bad as a 1000hp supra. I mean that car is just a dyno queen, with that kinda lag on the streets its useless unless you're at the track with slicks.

Is it bad for you to get 150 WHP at 4000 rpms when the stock motor will only put 135 at 7200 rpms? Actually it is laggier than the IHI but very streetable.
This is all tests we do to offer alternatives. But we could go with a 0.63 Turbine housing and get the boost around 600 RPMs earlier.

must.....save.......money.....

I really wanna see a video of this on the track

 

[Mr. 4500 RPM]

i get mazda3...you sponsor me! lol good work this makes me want to upgrade more and more...

 

[spacemonkey]

Wow that is a very nice curve. I love that Duratec MZR!

So what mods does it have internally? They have some pretty good stuff comming out for this engine...including cosworth heads.

Hiboost...fab up some motor mounts for a swap into a Protege Maybe one day. I love the look of the MSP but I love the performance of the 3.

I love logical responses to idiotic statements. Great work Juan and Co.

Congrats Juan!!!! Awesome!!!!!

 

[Captain KRM P5]

500whp in a mazda3 is insane

 

[HiBoost TS]

Congrats Juan!!!! Awesome!!!!!

Thank you, we do all this for you. Did you fix your issue? I think it is something in the intake manifold or the crank being off timing.

To get that much power out of a 4banger still amazes me. That is great work. I cant wait until you get it all worked out and all. When do you plane on taking it to the track?

 

[Kansei]

holy crap!

 

[InFlames]

wow....just wow

 

[smo0f]

any dyno for the torque?

 

[CWiLL]

again thats sick
