hey guys, this may be a newbie question, but humor me please, im not too familiar with turbo set ups.....ive looked at a few instances and noticed that NA guys with roughly 180-200hp are running mid to low 13's give or take......and turbo guys with over 200hp are running the same numbers maybe a little lower but not by very much.....now why is this???? I realize i have to take into account driver skill, however i was wondering if all things constant, meaning driver ability, car weight, tire psi etc, what set up would have the potential to be a faster car....fast spooling small turbo also, same hp. would it be a drivers race???? The reason i ask is because it seems the k series is the new wave, i have an EK hatch and i can't afford to swap the K. So to be competitive im leaning towards a turbo kit (stock b18c1 motor thinking of building that for boost) Need some constructive thoughts. Thanks in advance.

edit: sorry for messing up the title wasn't thinking when i first posted.

wow this is going to be a fun post if everyone gets on it
there has been numerous post that end up a big argument over this topic.

now to start it off
i would think that the FI would have the advantage if all variables were equal due to the fact that the FI will have more trq.
however that is what i understand through my research not from first hand so...

i think its power band related
most turbo cars (depending on turbo size) only have a certian amount of usable rpm range. such as max boost to redline

where as the n/a motors make power even down low were in a turbo car the turbo is not spooling yet

correct me if im wrong

but in a drag race how long are you in that rpm range?
the trq would more than make up for that short amount of time i would think

I believed you answer your own question...lol. Weight of car, tires and driver makes a huge difference.

As for your situation, If you already have the B18c1 in your car, then boosting it would be a feasible option. You should make at least 250-270 whp depending on your setup and with some slicks, that should be good enough for some low 13's maybe high 12's if you can drive.

first off im sorry if this has been covered already,.....id love to find maybe a 235hp turbo dyno and a 235 na dyno to compare where the power comes on, on the same motor........i understand that na power comes on right from the get go, but im curious to know that maybe because of excessive power in turbo apps, the power is not getting to the ground like on na applications.......so would a detune or lowering of the boost be benificial???

right....but i was wondering, in my chassis, wouldn't 250-270 get me deep into the low 12's na????

gear based boost controllers
lets you run the most power possible per gear to keep traction

and don't worry about it
i would rather see this over "I want to install my intercooler but can't figure it out without cutting or drilling something" ( https://honda-tech.com/zerothread?id=1992407 ) all tho it was funny

so how would i tune/set a gear based boost controller??? running at the track and finding what works???? also what kind would you suggest i buy??

95jeremie

once again not from experience because I'm still building my kit but i have the APEXI AVC-R

even tho I'm not boosted yet i have it hooked up and it is easy to use and looks good to

Godspeed07

awesome thanks.... boost it is then.....this set up will actually be for track racing....well this is my hope for the car in the future at least, but some practice at the drag strip would be great too....i really want to be able to hang with a K series, i don't think that it will ever be an option for me. Thanks again....any other comments welcome.

its all about traction look at the trap speeds of a turbo car way higher

Godspeed07

so in theory, a 200hp turbo car should run 13's in an EK chassis? (half gutted)

95jeremie

in theory yes

Godspeed07

hmmmm interesting....thanks for all the replys guys, its confirming a few thoughts i had, i think my goals are going to be low boost to start off with to see how fast i can get the car at minimal hp settings....thanks again Honda Tech yaaaayyyyaah!

asked the same question a while ago, with a lot of dumb responses but there are a few good ones...

wow 2005 that is a wile ago

93CX

Simple..

Wheelspin.

1.8turbolsvtec

it is all about tracksion last year at the track with my lsvtec turbo coupe ran a 117 trap at a13.6 wow with drag tires went a 12.2 at 118

"keep traction" doesnt exist with high-hp fwds.

gsrturbo-ek

n/a has instant power at all times turbo doesnt have instant power due to having to wait for the turbo to spool up and make teh power that matter of time it needs makes a diffrence. n/a also makes power low end but not most turbo setups

i have ls vtec boosting 7 psi @ 234 whp and i dont even hit 13's Best time was 14 flat. I must suck at launching with the federal street tires. 195 50 515. i have 2.36 60 ft

sjkelly

ok heres my opinion...i think the na cars dont spin as much so less spinning means more "go"...plus with the turbo its hard to keep traction obviously....it seems easier to have a good launch in a na car too wich is the most important thing in a drag race, plus most na cars are gutted to the max...it has nothing to do with the powerband because in a drag race your in you powerband the whole time (if you can drive)...i beat a modded 06 wrx and it had a more useable powerband and more torque, but who needs torque when you rev high...
