1/4 mile times. - Honda Prelude Forum

[SUB[EX] · 01-29-2003, 11:29 PM

Well i went to LACR Finally tonight. My car isnt running perfect yet but i really needed to get some times. My best time was a 15.6. I gota look up the sea level conversion but its not in the 14's which i really wanted. I was having a really hard time launching. I never had this problem with the f22. Wierd. I think i really need those mount inserts. It would give me a nasty bounce. The other thing is my exaust. Since im running a big FAT header and a FAT downpipe running into my small F22 cat i have a major bottleneck. I heard it would actually flow better with a stock header till i get my exaust. Oii what a pain. I just gota wait till march and i will have my exaust ready. Man this vtec beast is really touchy. If i dont hit it hard from the start she boggs the whole way down. If i hit it hard off the start i spin like mad then power the whole way down. What a pain. I still have that stupid vibration but hopefully that will go away with my balancer belt.

Jason ran a 15.5 with a short ram intake and a similarly ghetto rigged exhaust. 15.6 is good for a pretty much stock JDM H22 at LACR.

That conversion comes out to about 15

I have a 5th gen.. with Aem CAI and my best time is 15.0..

What is the sea-level conversion...I have never heard of that?

concLude · 01-30-2003, 03:08 PM

prolly adjusted for sealevel pressure, since at higher altitudes the pressure is decreased, making the partial pressure of oxygen decrease.

[SUB[EX] · 02-01-2003, 10:47 AM

Yea LACR is a very slow track because of the altitude. So they offer a conversion to sea level so you dont go race somewhere else. haha I guarentee when i go back i will have much better times. I think a vtec controller would make at least .5 improvment because i cant stay in vtec on my launch. But i also need to work on my launches. My reaction times were like .9 or .7. Way too high.

LuDe2K1 · 02-01-2003, 11:34 AM

My best reaction time was a .5...

Fast&furiuslude · 02-01-2003, 12:08 PM

my best is r/t is a .01

[SUB[EX] · 02-01-2003, 12:40 PM

nice
i had much better reaction times with my F22. It was alot easier to launch. There were no power spikes with that single cam no vtec, no secondaries. Much easier to launch.

You know better than posting in the wrong forum, right?

LuDe2K1 · 02-01-2003, 05:13 PM

R/T is .01...?? i've never heard of that.. i thought good reaction times are like .4 which i think is really good.. please explain..i go to the tracks a lot so i am sorta confused because i have never seen a .01 r/t before.. maybe it's just me..

[SUB[EX] · 02-01-2003, 08:19 PM

well its obvously possible to react that fast. You just gota start at the last orange. So as long as you dont RED light you can do it

LuDe2K1 · 02-02-2003, 04:03 PM

I always start at the last orange and my best r/t is a .4, .5.. i guess it's possible.. but just never seen it..

LudedudeSi · 02-02-2003, 06:01 PM

i feel like falling outa vtec is were im lagging also. i have a vtec controller that should be hooked up soon. if it made .5 diff. then that would put me at 14.3 and i would be a happy camper

i dun think its gonna change it that much though.

tb3 · 02-02-2003, 06:13 PM

.5 is the best you can do. Anything less than that is a red light.

LuDe2K1 · 02-02-2003, 07:13 PM

tb3.. that is what i am trying to say.. my best r/t is a .5 and i've never seen a .01 r/t before.. i would think that it would be a red light too.

[SUB[EX] · 02-03-2003, 12:42 PM

well i have redlighted and had a crappy reaction time. I really dont know how this is possible but it has.

The problem is that when i launch if i go at 4k then i bogg. Then my car boggs the whole way down the track. If i launch at like 5.5 my tires spin like mad and i hit about 8k then i finally get traction and my car feels FAST the whole way down the track. So the secondaries and Vtec need to stay on the whole way. People say i will lose HP if i lower my Vtec engagement. But what power am i gona lose? Will i lose power in first gear? 2nd and 3rd gear im alway above 5.2. I dontr see how im gona lose power. Maby in everyday driving but i dont need my engagement lowered for everyday driving.

jnkoh · 02-04-2003, 11:11 AM

.4 is the best you can get on pro tree

well ive done it too, but you have to seriously jump the gun, i wouldnt recommend it=) too easy to red light, and reaction times dont affect your ET's
