okay so about a year ago i lost my license for a year. i thought to myself this is a perfect time to rebuild my motor so i did. ive been working on this for about 4 months finally about 3 weeks ago i got it swaped and running. now all i have to do is wait another month and a half to be able to drive it.

anyways heres the spec on it. i was wondering what you guys think. what number should it be putting up???

***my header is all f'ed up from being hit on the ground. i think im going to up grade to the kiddracing narrow rep. that may add a couple numbers**


let me know what you think? anything i could have done diffrent. any ecu suggestions. anything.

 

I have no ideal about power production because no one except the builder knows anything about the assembly nor how well it will be tuned.

One thing, get rid of the whale ***** and find the correct length intake tube on the dyno.
As for a ecu, chipped p28 tuned with Neptune works for me.

 

because u have oem cam seals u'll make 500hp

 

duh thats why i got them. thanks capn obvious

 

You didn't say how high you are revving it.

 

im guessing he will at least rev it to 8500. no more than 210whp and that would be with a knowledgeable tuner...... you should take a look at the all motor dyno thread to get an idea.

 

With a 1.8L engine, revving to 8500 rpm, naturally aspirated, running pump fuel you will make a maximum of 230 HP at the crank. That is if the combination of parts you chose work well together and your tuner has gotten fuel mixture, ignition timing, etc correct.

230 BHP at 8500 rpm in a 1.8L engine corresponds to a brake mean effective pressure (BMEP) of 195psi. This is about as high a BMEP you will be able to get with pump fuel and that is only if everything is perfect. Likely, however, your setup is not perfect. A BMEP of 180 psi, which is more likely and reasonable, would yield 210 BHP. Take of 15% for drivetrain loss and your looking at a realistic 178 wheel Horsepower. Your result on a dyno will likely be this amount or less. If you use a dynojet you may get a higher reading, however this is not a true horsepower reading. It doesn't mean a dynojet is not a good tool, it just means the numbers then tend to produce are optimistic.

BMEP has been used by professional engine designers to accurately determine how much horsepower an engine will produce for a 100 years. Any dyno is a tuning tool and nothing else. If you are just looking for the highest whp number you can get so you can brag to your buddies, then you're just bench racing.

 

gotta hand it to ya Scott, you can really break it down. i bet if he chose to go with 84mm pistons, S2 P2 cams, some head work along with a functional intake system and a custom header i'm sure he could see 210whp.... that is if the tuner has everything dialed in at its best

 

thanks alot guys. scott you really know you stuff man ....props.

i was hoping arround 200ish bhp. and im am reving to 8500rpm. ive been looking at some intake system stuff. tb, manifold. betting intake.

 

Sorry Scott, but I know of several builds exceeding 220 whp. Check the dyno thread at the top of the forum. I don't know about this build.

 

Oh, I believe it. But like I said, a dyno is just a tuning tool. It doesn't matter if the reading is 100% accurate. You just want it to be repeatable so you can track the progress of your modifications. These calculations have been used for over 100 years to determine the maximum amount of horsepower an engine should produce by people who design engines and rely strictly on the scientific definition of horsepower and torque. If you claim you are exceeding it (peak BMEP), you are saying you are defying the laws of physics. But like I said a dyno is just a tuning tool and a dynojets numbers are a bit high. Also, there are only three ways you can increase power on an engine. Increase the displacement, increase BMEP (make the engine more efficient), or rev it higher. So if the engines you mentioned rev higher, the number is going to be higher. Using the same peak BMEP of 180 psi, revving it to 9000 instead of 8500 could threoretically yield 225 Bhp rather than 210 Bhp. Of course, his ports, compression ratio, cams, etc. would need to be proper to utilize that additional RPM. Not to mention the piston speed is increased by revving it higher so you will have reliability issues.

Nobody can tell this guy with 100% accuracy what his WHP will be until he has it dyno'd. We can only tell him the maximum number he should possibly see.

 

You do not need a fuel rail.

These threads suck.

I vote 39.461whp/74.901lb-ft.

 

Thank you, I had good teachers. I think that is a good, realistic goal. I can't stress enough that a dyno is only a tuning tool and the exact number does not matter. The true results will show themselves at the track. You could measure it with monkeypower instead of horsepower and as long as you got consistent readings and were using it as the tool it was intended to be.

 

Actually at 8500 rpm 74.90 lb/ft would be 121.7 hp. But I'm assuming you meant at a different RPM. Yes, these threads do suck but they're not going away.

Just messing with you

 

x 2.

None of these guesses are going to change what that motor makes when you put it on the dyno and tune it.

 

your kidding
