Wanted to share the 350+ WHP Protege dyno run

[status50]

PSI is not what makes power in a motor but air mass. If the engine is breathing more air than what the turbo can push, then the PSI on the intake manifold will drop.

Physics wins everytime. PSI is a measurement of BACK pressure. Back pressure is a measurement of when the motor can no longer ingest air under it's own power. Even 1 psi is 1 lb of back pressure. If you motor was moving more air than your turbo can push, you would not make PSI.

I don't know what numbers do not add for you, but we have a dyno run and at least 10 passes thru the track at 12.00, They went yesterday and again 12.007, 12.006 and 12.007.

You have all the info that we give to the forums as valuable info for other to compare.

The car is 2.0 liter with stock bore on its original engine block, lower Mazda compression pistons, Pauter rods, HiBoost basic kit, 450 cc injectors, Haltech F10X (fuel only) ACT clutch and MSP tranny.

357 WHP and 12.00 at 115 MPH

What doesn't add up is the numbers Vs MPH and psi from different times.
I quoted you already. You said you went 115mph on 30+ psi. HP is nothing more than a mathematical calculation as well. If you car is trapping X-amount of MPH and weights this amount you will make around this amount of HP. 30+psi is what you said when you went 115mph. If you weight in around 2700lbs and trap 115mph you are making ABOUT 385HP or 320WHP with a 20% drive train loss. Now you are saying 357whp or 426HP at the crank on 25psi. This is how I see it. 5psi less and 37whp more.. This is why I say it doesn't add up. I'm not trying to take anything from you. I think it's simply awesome to make 357whp regardless of how much PSI or mods. But when you have conflicting stories it causes alot of dought.

Come on now. Pat's just upset his Mp3 is slower.

Shouldn't you be building another built motor so we can all see it blow up again.

low blow!

Well, the info I am giving is what we get from the dyno and the numbers are what we get from the track. That is all.

Well Said Sir (2thumbs)

 

[hello2000]

Wow! Those numbers are on a stock motor. I wonder a rebuilt motor would do? Nice Job Juan!!

 

[JOMO]

Thats not a stock motor. Far from it.

 

[hello2000]

Opps.. I read the part where Juan said orignal block and .... yeah I'm retarded

No it's not. Its a measurement of pressure, not just "back" pressure. Walk around outside, you're under pressure. *gasp* Boost is referred to as pressure ABOVE ambient(when it comes to motors).

As far as trying to dissect drag times to figure out hp, just stop. There are too many variables and you're making yourself look like a douche. It sounds like you're attacking HiBoost, whether you mean to or not, so ofcourse all of us get defensive.

IT IS 95% STOCK.

Hiboost Turbo Kit w/FMIC & Haltech F10X, Hiboost Rods & Piston Kit, Eclipse 450cc injectors, Walboro 255 LPH fuel pump, Greddy Type RS BOV, S&R Motorsport JDM Cams and adjustable Cam Gear, B&M Short Throw Shifter, 3"inch down pipe and exhaust, ACT Clutch and Fidanza Flywheel, VICS & VTCS removed manifold, ARP studs, Cometic gasket

I don't beleive anything is ported and/or polished in that FS. The only internal parts are Hi-Boost pistons which are OEM except from being machined for a 8.5 comp. ratio and machined again to fit the forged rods, Pauter rods and a set of Mazda JDM cams with aftermarket cam gears.

Nothing far from stock... Most modded internals are Mazda parts!

 

[FlyinMSP]

How much all the above would cost (including labor) ?

 

[Metal MP5]

i've seen 12.9 @ 116 on a 325whp proteg @ ~17psi ... all numbers don't always make sense.
