Wtih a 2.2 60ft why im at mid 15's? - Honda Prelude Forum

I was looking through some of the times for other si's and some of you guys have like 2.3-2.4 60ft times and low 15's in the quarter... What the hell is wrong with my top end?

My best time was 15.533 with a 2.23 60' time.

It's tough comparing other times at other tracks. If you are at a higher elevation, your top end power may suffer, so even though you are getting a good lauch, once the motor winds out there is less oxygen available, and less top end hp.

What is the elevation of the track where you race?

Ouch bro. with 2.2 60 foot i dont care what track you are at you should at least be hitting low 15's. Somethings wrong with your car..check it out.

oinkus · 04-20-2003, 03:05 AM

i say just except your times.... i'm hitting 15.4 with a 2.3 or 2.4 60' and i'm traping 92mph most of the time

i should be low 15's or breaking 14s

i raced an civic si and he got 15.4 @88mph

Fast&furiuslude · 04-20-2003, 11:10 AM

15.4 @ 88 = no top end but good bottem. probably got a good launch.

oinkus · 04-20-2003, 05:20 PM

^^^ yup he got a 2.2 60' and he was on falken azenis

Brady92/4WS · 04-20-2003, 11:09 PM

i got a 2.2 and im on some ****ty ass 400 tread wear tires that were on the car when i bought it... I'm not totally sure of the elavation, but its pretty close to lake michigan so probably sea level or damn close.

Fast&furiuslude · 04-21-2003, 12:06 AM

add 3 bottles of fuel injector cleaner

youll hit low 15's no time.

what was your 1/8th mile time? H23s lack top end in a bad way....my freind has one, take his 1/8th time and mine, then his 1/4 and mine...i put 9 tenths of a second on him from the 1/8th to the end...my old H23 had no top end either, my traps were in the 88 range, which is good for 15.4ish, generally speaking you need 91 to 92 to get into the 14s...and thats barely there
more like 15.2 to 14.99999 with the perfect run...this is FWD too..so, there ya go

I ran a 15.4 with upper 89 trap speed, with a 2.3 60ft. What RPM are you shifting at? Play around with your shift points a little bit, it very well may help.

Fast&furiuslude · 04-21-2003, 12:21 PM

shift at 6500

Brady92/4WS · 04-22-2003, 06:26 PM

yeah i was thinking that maybe shifting at 7000 isnt beneficial, im not sure of my 1/8th mile my timeslip is at home somewhere

Strangely enough I get my best times shifting a tad bit after 6000, I'd recommend playing with your shift points the next time you go to the track. The H23 doesn't breathe well at high RPMS, even with mods.
