Who has the fasted NA Protege?

[Installshield 2]

wow...old thread...

I finally have the engine in my garage at least now...and finally have some wiring figures and schematics for triggering to Linkelectro...Oddly enough I finally have the cash for the full exhaust and the standalone, and the computer people are spending a good deal of time getting back to me...I got into NA at first because I always have a hard time dumping a ton of cash all at once...and I am days away from dumping 2,000 bucks in about 10 minutes...

I still hope to have it tuned and running before my last semester of school, but I also said I would have it running before christmas...I suck...

Can't wait to see you up and running.

 

[stdntDrvr]

do you have a 1.8L?

want some free magnacors?

Can't wait to see you up and running.

Install: I want to see the engine up and running! In a car, no less. =) Refresh my memory, though; What were you shooting for for a redline? And for that matter, you're doing it with an unmodified head, right?

 

[Installshield 2]

about 7800rpm or so for the street...putting the peak power down by a couple hp, but it will be much safer than the 8200 rpm on the brake dyno...

the head obviously needed new cams, and I did get around to some minor porting and mirroring the exhaust side finally...It also recieved the Eibach valve spring kit for the second build...other than that it was left alone...stock TB, stock intake manifold (other than the port matching, forgot about that)

You asked how NA cars run?

Like s***.

 

[twilightprotege]

mine runs like stock...it's feel like stock too if i didnt have the hard awr enging mounts

Are you gonna go turbo then? (drive)

i still dont beleive that drivetrain loss is a percentile..

you can calculate it for every car, thus making a precentile from the data. Do it many many many times over many similar types of car and you get rather accurate FF, FR, AWD drivetrain loss averages.

well, If I was going to say turbo my protege, that would of happened over a year ago. I haven't done anything (or plan to) in hell, months.

i suppose if you take the chp and whp after all mods and made it into a percentile, that makes sense to me. but when someone tells me that you lose 20% to your drivetrain, ok, i have a 1000whp engine, and i lose 200whp to the drive train? seems a touch abseurd to me..

 

[Installshield 2]

Yeah there are a few threads that we touched on this I think...You can say its a percentile...which is true, it can always be a percentile basis...but that percentile is not fixed...meaning the percentile of drivetrain loss on a stock protege vs. a heavily modified engine is not the same...only because of the increase (or decrease if you suck) in hp...not because the drivetrain becomes more or less efficient...that is a whole other beast that doesn't really come in until power is extremely high...

I prefer to just say that the gearbox devours a certain amount of hp...what that number is is based on what our actual stock bhp number is...its not quite 130...but if you believe it is (no use on arguing on it, because it really doesn't matter), just figure you lose about 30 hp to the wheels...always...so if you have 200whp, figure you have roughly 230bhp...and hopefully you can see why the fixed percentage notion appears to be flawed...

this is where it gets funny...You definately would lose a lot of power from a 1000bhp powerplant hooked up to our gearbox, axles, wheel carriers, etc...so in this sense you would not lose that identical amount of "30" hp I was talking about in the above post...in reality you would break something...but mathmatically you would create heat gradients and metal fatigue flectures (prior everything scattering out of the bottom, sides, and top of the car) that would sap out a fair amount more power than that of a 200bhp engine hooked up to the same drivetrain...

again though...it doesn't matter anyway...your bhp number is of little importance...and if you were trying to make 1000bhp out of an FS, you would have stopped a long time ago...if somehow you did do it, you obviously have the beans to realize that you would need a s*** load of work done to the rest of the car to handle it...in which case, you wouldn't lose a whole of bhp to the wheels...but I just said that was important in the first place...I am lost...

 

[twilightprotege]

i like to think of it as x whp + % of total engine power.

 

[Gen1GT]

I'm with Jamie on the drivetrain debate....

 

[Nightmare]

that makes sense.

I am interested to see what the real numbers are on a stick Protege. I believe my Mustang loses about 20% or less through it's manual tranny.

My P5 dynoed at 105 to the wheels (full exhaust after stock manifold and lightened flywheel). If I was lucky I had 140 to the flywheel. My mods don't do crap for NA as it is getting ready for turbo.

 

[Nightmare]

the full exhaust helps, slap a header on that and you should dyno in at 115 or so whp
