Ok, there's this kid around town with a 92'-95' EX coupe that is pretty new to the import scene and already knows everything. A friend told me that he was bragging about his horsepower rating, something in the 200+range. Not sure if he was talking to the wheels or flywheel, or if he even knows, oh yeah it hasn't been dynoed.

Anyways, this ASSumpion is based on the all the standard bolt on mods plus a bigger fuel pump, fuel rail and f/p regulator/riser. He seems to think that uping the pressure will get more fuel to make more power. Did anyone read in SCC the article on how to figure out how much horsepower your injectors can produce? I figured out by running the formula that his fuel system can handle up to 170 - 190 H.P. with stock injectors, which he has.

Now this is where I need some help. I would think that the ECU is capable of sending more fuel to the injectors up to a certain H.P. then you would need to upgrade the fuel system. And even if you upgrade the fuel system, the ECU will STILL send the same amount of fuel, the only difference is that the system is now CAPABLE of more H.P. than stock. Since he did up the pressure he's going to get more fuel in, but will that just make him run rich and not make more power? He's probably adding the horsepower that each company claims their product adds. Unless this kid found out how to get an extra 80 horses from bolt ons! HAHAHA Help me prove him wrong.

Although "possible" to extract 200hp from a D16 (I know, before I went Turbo I had somewhat mapped out an NA plan for my D16), it's VERY VERY expensive and requires a helluvalot of internals work to the motor. Bolt-ons? No more than 130ish to the wheels and that's being quite generous! My opinion about this guy and his 200hp EX....

 

To answer your question.....NOPE!

Next, the ECU is not capable of sending more fuel the the injectors can physically....sure the ECU will tell them to send more fuel but if they can't then there isn't going to be more fuel.....er, just finished reading what you wrote I agree he is a moron...next time you run into him just say let me see your dyno. Any one making claims like that would have the sheet with them and even then it would be hard to convince someone who knows what they are talking about.

I had a friend who pulled this.....97? Tegra GS with I/H/E and he claimed.....GET THIS 200/200....WTF!?! Now at the time I wasn't into imports and didn't know but, how the hell do you get 200 torque out of a 1.8 with just a I/H/E!?!

 

I'm with you VTC_CiViC, I have no doubt a D16 can acheive 200+ but not without a wallet that is the size of your head! My guess was about 130 to the wheels.

 

really i don't think it would be that expensive to build up an all motor d-series. u can get srp pistons for about 350 buks a set and u could use integra rods (just gotta get them resized). the most expensive thing would be head work.

answer to the question ----------> hahahahhahahahaah
a single cam! what a joke! takes to much $$$ for that motor

 

Im with that other guy maybe a 130hp to the wheels but that is about it. And I also do not doubt that a single cam can make good power but it is not gonna make it on just bolt-ons. It takes $$$ to build anything up and the b series arent exactly the fastest things put on this earth. To make them fast you have to spend alot of cash also. So it almost evens itself out.

 

Just look inside his car. If the gauge cluster is painted or he has a monster tach, he is probably full of crap!

Even using ZC pistons, D16A1 rods, and alot of other "hand-me-downs" I had planned, it was still gonna be ALOT to get the D16 to squeeze out 200whp trust me. I know it can be done, but really, look at the amount of $$ people toss into B16's or even B18's to get em inthe 200whp zone, now multiply that by the handicap of 1 cam running the show and the lack of selection when it comes to D series high end parts and you'll see how expensive it can get. #1 reason I went turbo... well that and the BOV

 

u need to not worry about formulas for hp per fuel injector and learn how to pick out the bull ********. He my friend isa bull *******.

 

hey guys, to understand the rice boy we have to become the riceboy...i think i know why this kid thinks he has 200 h.p....i used to go to school with this one kid who had an intake header, exhuast and pulleys...that's it! now this was on a 94 LS and he claimed the thing had about 190 hp because he thought you just go and add 7 hp when you put on an intake, another 10 hp with the exhuast, 10 more with the header, and another 15 hp with the pulleys. don't forget guys, this is sometimes the manufacture's fault that some people belive EVERYTHING they hear and think that by adding a plley kit they'll gain EXACTLY 15 hp.
--justin

 

he's probably adding all the manufacturers claims, plus not useing "to the wheels" stats.

start w/ 125hp
add 15 for intake 15 for exhaust 15 for header 10 for high flow cat 5 for spark plugs 5 for ignition 5 for advancing the timing 5 for plug wires and of course

25hp for all his VTEC stickers...
and there you have it.
EX over 200hp

 

Theres no way in hell he can get 200HP at the wheels without F/I. Its hard enough to get it with b16's and b18's with N/A. With just bolt on's he'll be lucky just to get 130. I think realistically.. EX SOHC rate at 127hp if I remember right. At the wheels that should roughly be 102-108 at the wheels. I/E/H is usually only good for about 10-12HP FOR ALL THREE put together. (CAI will get a little more) I doubt he even has 130.

 

Well, I have a 92 Si.
It has I/H/E and make 125 at the wheels. Thats not bad if you ask me, I might be able to get 130 at the wheels, but I seriously doupt it. 200 hp from a D16Z, no, not without F/I, or MEGA internal stuff. I would like to get 140 at the wheels before next year, anyone have any idea? I heard good and bad about Gude cams, anyone have experience with them?

 

Yes, gude makes very good products. I recommend unorthdox cam gears if you're upgrading those...

 

I love my Gude cam (2522) in my D15! It gave me really good torque on the freeway and pulls much better than stock.

 

Oh, I know how he's doing it, he's playing Gran Turismo!

 

Unfortunatly I hate to tell u this but not only is it possible to get 200 flywheel hp with a D16Z6 it is quit often done, even with stock injectors. SCC's article was quit good but mislead some ppl. You can up the fuel pressure via an AEM fuel pressure regulator to in essence up the rate at wich the injectors flow. 160 hp at the flywheel with a D16Z6 can be realized with I/H/E (check out asia.vtec.net and their whole SOHC series). Now with hondata and some smart tuning its quite easy to get 200 hp with what appear to be basic bolt-ons. I know because i used to beat chumps in my CRX HF running this setup. And by chump I mean people who think their extremely fast because they merely swapped their motor.

 

Does he have lighted green windshield squirters on the car?

 

I realize that the ECU is only going to squirt as much gas as it needs to and I realize that if you up the pressure, you can get more gas because you're sqeezing more through the injectors. After the SCC article the had a follow up equation to compensate for more fuel pressure. But you're saying that to get more power, all we have to do is squirt more gas? Won't that just make you run rich? you show me dyno charts and a parts list and I might think it's legit, and in the meantime I'll check out that website.

 

hmm, that's funny. when i only had bolt-ons my jdm b16 rated at 170 horses only got 150 to the wheels. man, guess i should swap it out for an ex! some phuggin people dood.. just ask him how many valves he has PER CYLINDER and when he says 16 just walk away.. hehe..

 

200hp with "bolt Ons"?? I guess if you bolt on a turbo.. then yeah!! As for the site.. those dynos show 110HP at the wheels. So where are the other 90 horses were left in the stable. Please dont believe in everything you read. Adds always claim 10-15 Hp from intakes.. is that really realistic?( maybe an old Dodge)
Go by experience... not by what you read.

Trust me, I'm not believing everything I read, I wanted to give the guy a chance to back himself up. I went to the web site and didn't find much to back anything up. Only the recomendation to swap a B-series in!

Anyway, I guess some people really want to believe the performance makers claims. You ever look at some of the dyno charts from companies? Their 10 H.P claim is usually one small bump in the chart in a 500 rpm range. Thru-out the whole powerband it's only like 1-3. And forget that untill half-way through the RPM range.

 

>>160 hp at the flywheel with a D16Z6 can be realized with I/H/E (check out asia.vtec.net and their whole SOHC series). <<

Maybe I'm looking at the wrong SOHC article on vtec.net, but here's what I found:

"Again, the use of such a package on the 1.6 SOHC should give approximately 10% or so upgrade in max power, upping the final maxpower of the 1.6 SOHC to around 130-135 ps at the engine."

This is from the asian site, so they're using a different SOHC motor from US spec, but that only affects the initial hp rating, or "ps" as they put it. If someone else on the same site is writing articles about the exact same tuning package and claiming 30 more horsies then I'd have to question the validity of the site. But, I didn't find that article...

 

to get more fuel, you get higher flowing injectors and a larger fuel pump. that same stock amount will be greater.
