winning a v-tech db15b

[LyvvRacingCB7]

i have a question that has been bothering me for awhile..well when my friend bought his car from a dealer he didnt know it was a d15b motor and thought it was just original motor in a 95 civic(all he cared about was vtech) . when he got it i took a look under the hood and said wtf its not the original motor sooo we took it to the track to race againts me cause racing on street is too dangerous....i have a f22a1 with just a short ram and nothing else well when raced, from the lauch i took him already and all the way about two car ahead sooo am i suppose to beat him that bad? he is a good driver and we test others to drive it also....or is his car mess up he has a p28 ecu... i research it and they said d15b is 130 hp and f22a1 is 125 hp

Difference in gearing maybe?

[steelbluesleepR]

lighter car, similar power ratings, different drivers, different tires, suspension, gearing, etc. are all variables that could make you win or lose.

oh, and its vtec, not v-tech (that's an electronics company). not giving you shit, just trying to help out. saying it wrong it makes you look ignorant.

thx for the correction but does the f22a1 has more potential to be strong for a non-v?

[vietkid_2006]

lol. vtech.

i beat my friends civic's all the time we have same mods. F22A is very powerful. once you start building them.

Laughing at the kid isn't helping him out. I bet you were born a naturally gifted master technician. *rolls eyes*

Each motor has potential. One of our vendors, Bisimoto, is building a 700hp street civic for Super Street magazine as we speak. What he is really famous for is the naturally aspirated F22's he has built. It's all relative when you talk about what motor can do what. Each has its pros and cons. It's all about what you do. Hope that helps out.

and yet even after your post people still write "vtech"

VTEC is in a honda

VTECH makes phones and other stuff.

vtec is not the all-powerful thing that many people believe it to be, IMO anyone who swaps to a different motor just because it has vtec is a moron. all does does is allow you to have fuel economy below the crossover and performance above. if you put a vtec-killer cam with the same profile as the performance side into an h22, it will have the same power.

that being said, the f22 has as much or more potential as the h22. the head design is vastly superior and is actually the best flowing head that honda made until the f20c in the s2k. look at bisimoto's f22ax that he built for super street's top shop entry. 360hp+ naturally asperated and is still reliable enough to put in a street car (and they did). also, look at the f22 builds on this site. there are a couple that have turned some impressive numbers with stock internals and a cheap DSM turbo kit and still others that have done a relatively mild internal build and come out with numbers comparable to a stock h22.

its all in the research you do. it may be easier to make power in an h22 initially due to the superior industry support they have, but once you get to a certain threshhold the head will be holding you back.

That's not necessarily true. VTEC allows a broader powerband as well. You're running 2 cam profiles. One for low RPM, and one for high RPM. When you run a VTEC killer cam, you're losing that low RPM powerband.
In a drag racing situation, yes it can be beneficial to do away with VTEC... because you're using the high end the whole time (and the soggy bottom will probably help keep traction off the line). Plus, I believe you can convert everything to a standard non-VTEC setup, and do away with some of the valvetrain mass (this I'm not 100% sure of... and i DO know that a VTEC valvetrain has more mass... another reason why Bisimoto focuses on non-VTEC for the most part)

In a road race situation, VTEC is very helpful... as you can often be using all parts of the powerband. VTEC gave Honda quite an advantage in many racing classes, before other automakers had anything to compete with it.

And remember to, that out f22ax are way more torquier than the civic engines, you make torque by having HP, you make HP by having torque, you win races by torque not HP.
your f22a1 has 130tq (correct me if i am wrong)
and the d15 has almost about 100tq cuase the civics are light and do not need to much torque.
And out motors have more torque than HP

Wouldn't that mean that the Prius's electric motor should make it win every race, with 295 lb·ft?

[D1sclaimer]

generally (and I only mean generally) the saying "no replacement for displacement" holds true.

You have .7L on him with an f22 to his d15.

I'am not talking about electric cars....its about our f22ax motors, not electrics

[LeosCB7h22]

vtech phones has d15 models now?

Wanna have fun with a prius? Turn the engine off, put it in neutral, and try and push it? See what happens.
