1.6L L4 SOHC 16V 1995 honda civic EX how much horse power you guys thinking?

 

Stock hp ratings on a 95 civic ex were 125 hp at 6600 rpm and 108 ft-lb at 5200 rpm.

 

Would that apply to any eg or just a 1995?

 

First off, stop calling it an EG. An EX isn't an EG.

Second off, click this.

Third, and finally, yes, the numbers for a D16Z6 are 125/106, but those are flywheel numbers for a brand new motor. You lose a significant amount of power through the drivetrain, and through the gradual wearing-down of any motor. An original, OEM D16Z6 is lucky to put 90 to the wheels nowadays.

 

What about with boltons, (intake, exhaust, plugs/wires)

 

And 90 is underrated. Maybe 110-115 to the wheels new, so probably 100 to the wheels.

 

You are severely underrating how much power is stolen by the drivetrain.

Bolt-ons don't do a damn thing without a tune.

 

I'm not sure if my eyesight is going bad, but I certainly didn't see any dyno tests to back up your claims. It's my knowledge that drivetrains usually steal 10 percent of the flywheel engine hp. 125 = 12.5 hp ----> 112.5 whp NEW.

 

I just got my car tuend for my boltons. +9 whp.

 

I'm not sure where you got 10% from. The "rule" has always been 15%, but even that is technically wrong. The SAE documentation showing it is behind a paywall, but Modified Mag has an acceptable article that explains it (kind of). 14%-17% is more realistic for stock Honda manual transmissions with stock (or stock-similar) wheels and tires. There's a LOT behind it. Everything from the gear ratios, to how the car is being tested, to the size and weight of the wheels and tires. Big, fat, heavy wheels ruin your power. Long, tall gears ruin your power. Gradual acceleration will give lower numbers than a full WOT pull to redline.

126 is brand new, with perfect compression and perfect oil. Less-than-perfect compression, try 110 BHP. Since 14%-17% is the recorded average for Hondas, let's cut down the middle and use 15.5%. The oil isn't brand new, the oil pump isn't brand new, seals are worn and creating more drag, and you're lucky to have 90.

So, $300 in bolt-ons, another $300 for a tune and the related hardware, and $600 gets someone 9 horsepower...awesome. Great waste of money. You could have saved up some more and gotten an 11-fold increase for only 2-fold more money.

Yes, I use real numbers and math, not "feelings" or the grapevine. Nope, I'm not sorry.

 

I paid 80 dollars total for the boltons. Exhaust was already done when i bought the car.

 

And i'm smacking fuel cutoffs and ripping Vtecs with straight cut gears, so losses are much lower. And manual, with tall EX/Si (s20 b000 IIRC) gearing, = massive power increases to the wheels.

 

Shut up crazy. You're out of your element in literally every thread you post in.

 

stock d series with bolt ons= very not fast. your argument is nonsensical.

 

crazy, people like you are the reason this forum can't have nice things. Someone approaches you with real, solid, verifiable facts, and rather than countering with more real, solid, verifiable facts or admitting that you're wrong, you go straight into stupid mode. You may think you're being cute, or funny, or "trolling", but you're none of the above. The only thing you're accomplishing is annoying the most knowledgeable people of this section, and making them not want to come around anymore. You're gaining 5 seconds of personal amusement, while doing permanent damage to this forum as a whole.

Honda Tech used to be the #1 technical car forum in the world. We're barely #7 now. We aren't even #1 for Civics (we're #4), which is our most popular sub-forum. Posts like yours constantly shitting up the forums isn't the only cause, but it's definitely high on the list. If you're going to keep posting in the technical forums, keep it technical, and stop dragging the rest of us down.

 

^^This...

For the record, I plan to be a bit more heavy-handed towards bullshit, off-topic ramblings that detract from the forum.

Technical forums should have technical discussion, not argumentative nonsense
