Re: how much bhp does a 89 civic si hb have stock (bigstevo106)
105 is the factory rating in the manual.
That # is very debatable, since most will push 105-110 WHP on a Dyno. I would venture to say that Honda under-rated the HP by 15%

Then why would HONDA, the manufacture of the car say it's 105? Do you know of any information from HONDA that verfies the HP rating @ 108? A pamphlet, a sales sticker, anything at all?

Re: how much bhp does a 89 civic si hb have stock (jisu009)
....To answer the original posters question.
Quick definition of BHP, so everyone is on the same page here:
A measurement of the actual usable power (not calculated power) measured at the output shaft (usually the crankshaft) rather than at the driveshaft or the wheels. Thus none of the auxiliaries (gearbox, generator, alternator, differential, water pump, etc.) are attached. It is called the brake horsepower because the shaft power is usually measured by an absorption dynamometer or "brake." This is not the brake on the vehicle's wheels but a testing device applied to the shaft. This instrument is applied to stop or absorb the rotation of the output shaft and returns a value.
I would *estimate* the BHP of a D16A6 at 120HP, stock out of the box.....

Good answer. I'm surprised at how many people do not know what the "B" stands for

I care. 3 HP is the difference in a race weight of 2310lbs. or 2376lbs.

I too have a helms for a 1991 Civic-CRX and the hp table was never changed from the '88 spec. The 105-108 bump was from a slight cam profile change and corresponding ECU mapping changes.
Chances are the Helms don't get revised too often, just look at some of the locations where they spec. the bolt size (ex. 12mm instead of 14mm, etc.). Or for that matter look at the line drawing of the body in the front... It has a "ZC" type hood bump and that rear spoiler, both never applicable to US models. The Helm's are good, probably the best out there (no doubt due to the info supplied to them from the Honda engineers/tech writers), but not perfect.
I do recall seeing the hp change in all the reviews at the time in C&D, R&T, etc. and some Honda material. The only thing I have left is the showroom catalog you typically pick up, so here you go:
P.S. PM me a link when you post up that exhaust system you mentioned in the other thread. It sounds like something I've had in mind but am too lazy to find a good fabricator for.
