My Turbo 3 Dyno 245whp and 258tq 8psi

[Gambino]

The 2.0 is a more turbo friendly motor than the 2.3. The 2.3 has more torque, but the 2.0 will boost more at the same compression ratio without sacrifying power.

do you think this has anything to do with the vvt in the 2.3?

 

[hyck]

doesn't the 2006 3i come with a vvt ?

 

[nate0123]

yes

 

[vindication]

I beleive so.

that dyno looks awesome, maybe a tad bit lean, but thats always the choice of the car owner and tuner, who am i to judge? The torque curve on that is something else, once more turbo'ed 3's start hitting the streets, they might be giving our neons some competition. (glare)

O RLY?

your site says the kit is for the Mazda 3s - does the same kit fit the 3i 2.0 sedan?

The kit is a bit diffrent for both engines. There is a slight change in some piping and the mapping in the Haltech is different. Other than that, everything is the same.

whats 245whp in reg hp??? always confuses me...sorry for the ignorance

who cares how much it is at the crank, whp is what matters.

i just dont know what that means thats why, i can understand crank and how that works with the weight and what not but wheels i dont know how that works

 

[DE31]

at the wheels is the power that actually reaches the ground at the crank the power still has to go through the drivetrain and such. i could be leaving something out though

thanks that helps a little

Wheel horsepower is the calculation of driveline loss. Example the whp is 245 so the loss is between 10-15% so let us use say 12.5% avg. So that would make it a loss of 30.6 whp. So the total of the engine crank hp would be an estimated 275 hp.

Foot note: for those who dont know, some car magazine's (C&D, R&T, Automobile etc.) quote manufacture engine hp figures so as in the MZ3 2.3 the quoted engine hp in 160hp so if you put that car on say a Dynojet dynomometer, the figures will be about 140 whp using the 12.5% driveline loss.But these are pretty much estimates.

doogie.. just a quick question..

what about bhp (brake horsepower)?

I realize the term was used back in the muscle car era and its rarely used now. What exactly is that a measure of? Is it what the engine is capable of putting out?

Anyway.. I could never wrap my head around the bhp thing.. everything else made sense except bhp

Here, this may help you understand the philosophy of Hp, BHP, WHP, Tq.

bhp = hp
whp is the amount of power that is giving to the wheels after the gearbox, drivetrain, etc
