I am only going to post the best time because the others are so embarassing.
Also I don't want to post the 60' times because they are horrendous.
Lastly check the low MPH the way I figure a healthy B18C should do about 98-99 MPH.

Best time 14.913 MPH 92.75
Best MPH 93.22 ET 15.11

Also, I am not the worlds gretest driver so I don't want to hear improve your 60'. The MPH was fairly consistant and I feel that tells alot about the power an engine is putting out.

The only thing I can figure is there is somthing internally wrong with the damn engine I will have the new shop do a compression and leakdown to see.

If anyone has any ideas on what could be wrong with the car (not driver) I would be glad to hear it.

 

seriously bro get the engine check something ain't computing here

u should be atleast at the mid 14's I believe with only ur mods

I know man I am really pissed off.

 

b16s have better numbes than that midly built. Do you have good tires and suspension that type of stuff.

 

Theres nothing wrong with his car I doubt, sorry to say but its the driving

The launch is everything for a Honda and can make a huge difference in your trap speed

For example, I know Im good at driving but have little mechanical knowledge other than bolt ons and wiring.

My friend has a B16a1 obdo crx without lsd, best time he could cut was 15.1 with like a 2.4 60'. We changed cars and on my first time ever driving his car I cut a 2.2 60' on Falken Ziex tires, I launched at about 4400 where he goes at about 3500, and I ran a was slow shifting into third, I stil ran a 14.8.

With practice I would have done even better. Maybe a 14.5

You may think you have your car downm but you probably dont. Go to a dyno shop, just ask for one baseline pull. Make sure you look at your cars tach while doing this, watch them give her ****, see where your tach says your rpms are at and see how far off they are from the dyno sheet. Youll also find where your engine stops making power and you can get your shift points down.

In my crx (sohc zc, i/h/e, pg7 ecu and a 65 shot) I was shifting @7000 according to my tach and thought I still had a bit left because of my new pg7 7200 redline.

First time on the dyno, my car was making optimal power up until around 6700, you know what 6700 on the dyno was showing up on my tach as???

7300++ I was shifting atleast 400 rpm early for weeks!!!!

I was dumbfounded. Got it out of the shop and bought a proform shift light thats accurate as hell. Set it up to 6700 rpm and went for a quick drive, sure enough, the light wouldnt go off until my tach shoul over 7200 rpm.

My friends all thought I did some internal work on my car while I was at the dyno because my tach showed me going up and over 7grand

Thats my 3am saturday story

Practice is seriously not overrated, its underrated

 

Theres nothing wrong with his car I doubt, sorry to say but its the driving

I knew an idiot like you would show up. As I stated my driving has NOTHING to do with the low MPH.

 

my best time is a 15.3 near stock b16, don't fret over a few 10's of a second, unless drag is your thang

practice makes perfect, but it also breaks stuff

 

Im an idiot?

Youre the one that thinks your embarassingly low 60' times that you wont even post wont affect your 1/4

Also did you read my post *******. Maybe youre shifting early...... or even late after your engine stops making power

****, glad you appreciated it though NOOOOOOOOOOOOOOOB!!

Look man I don't need your help you are the kind of person who teels stories of running 1.6 60 foot times on street tires. Did you even read my post I am complaining about the MPH so no I dont want your help.

 

1.6 60"??? Im pretty sure I just posted 2.2

And yet you posted none......

Read drivens track thread, he ran the exact same as you and hes more modded and probably has some more experience

dont get your ***** in a knot

 

Look I am done arguing all I am saying is the true indicator of engine performance lies in the trap speed and if you are to stupid to understand that I am sorry.

 

And you dont think that shifting early or a shitty launch accounts for your traps being stupid low......

Its not arguing, are cars are old, your motors probably beaten, you admitted your not a great driver..... and you complain about low traps.....

 

And you dont think that shifting early or a shitty launch accounts for your traps being stupid low......

When do you suggest I shift.

 

shitty launch accounts for your traps being stupid low......

Actually spinning your tires half way down the track raises your MPH.
Proof is in the fact one of my worst times has one of the higest MPH.

 

Youll have to jump on a dyno or just feel by the pull of your car when your not making peak power.

Or find someone else with a gsr swap with a stock dyno pull

 

Youll have to jump on a dyno or just feel by the pull of your car when your not making peak power.

I am throwing it on a dyno next week so I can see if anything is wrong ill check out when it peaks.

P.S. Sorry if I am a little touchy about this subject, I have put a lot of cash into the project for poor results. Also I have ran into jerks on other boards that claim stupid fast 60 foot times on stock motors and on street tires and when I found facts and proved he was making it up I got kicked off the board.

 

92MPH is indeed a low trap speed for a B18C swap. I myself am bad at launching. But I was able to run 94-95MPH with my B16A swap (although the car was a lighter 1988 DX). In your heavy SI, your trap speed should probably be around 96-98MPH. There are, of course, alot of things that can be wrong with a swap:

1. The motor itself. You might want to get a compression test. It could be tat you got a bad motor. This, of course, might not be the case. But it is a start.

2. Your valve/ignition timing could be off. Definitely check to see that your timing makes line up for the valve timing and that your ignition timing is at least within stock specs. If you cannot even get your ignition timing close to stock, your timing belt is probably a tooth off.

3. Your car could need an ignition tuneup. Have you changed your cap/rotor/wires/plugs? It sounds simple. But it could help. Especially if you notice that your car is running/idling rough.

4. Don't forget the fuel system. Most people completely ignore this. But it can cause BIG problems. Change your fuel filter. And make sure the pump is able to supply the motor with enough fuel. Oftentimes, your pump is not due to old age. You might just want to replace it regardless.

5. Check your wiring. Make sure your VTEC is actually engaging. All too often, VTEC motors run slow because VTEC won't engage.

6. Check your secondary butterflies. If these are sticking or otherwise nonfunctional, you could be losing power as a result.

7. Poor quality bolt-on parts. Let's face it. If your stuff is garbage, you could actually be losing power compared to stock.

As for shifting, DOHC VTEC motors tend to have power peaks that are VERY close to the rev limit. Typically, the best time to shift is right at the redline. Just don't bang the rev limiter. That REALLY hurts both ET and trap speed.

 

Now this is the type of advice I was hoping for I will takle them one at a time.

1. The motor itself. You might want to get a compression test. It could be tat you got a bad motor. This, of course, might not be the case. But it is a start.

After this run at the track I think this is probibly the problem I will dyno and if that is no good I will do a compression and leakdown test.

2. Your valve/ignition timing could be off. Definitely check to see that your timing makes line up for the valve timing and that your ignition timing is at least within stock specs. If you cannot even get your ignition timing close to stock, your timing belt is probably a tooth off.

I did the ignition timing myself it is good I am not sure about the valve timing.

3. Your car could need an ignition tuneup. Have you changed your cap/rotor/wires/plugs? It sounds simple. But it could help. Especially if you notice that your car is running/idling rough.

All this has been replace recently.

4. Don't forget the fuel system. Most people completely ignore this. But it can cause BIG problems. Change your fuel filter. And make sure the pump is able to supply the motor with enough fuel. Oftentimes, your pump is not due to old age. You might just want to replace it regardless.

Changed the fuel filter recently the fuel pump was changed about two years ago if it is a fuel issue it should show on the dyno.

5. Check your wiring. Make sure your VTEC is actually engaging. All too often, VTEC motors run slow because VTEC won't engage.

I can feel VTEC engage.

6. Check your secondary butterflies. If these are sticking or otherwise nonfunctional, you could be losing power as a result.

Could be an issue do you know how to check them?

7. Poor quality bolt-on parts. Let's face it. If your stuff is garbage, you could actually be losing power compared to stock.

Could be as well but I doubt it.

Thanks again for some useful info not just the same old your a crummy driver crap.

yep, yep and yep.

:EDIT:
A lot of people don't realize all of the factors that come into play when dealing with quarter mile E.T.'s.

1: dew point

2: track temperature

3: air temperature

4: wheel weight

5: tire compound

6: suspension components

7: vehicle weight

8: driver error

9: fuel type

10: engine speed during launch

It's hard to pass judgment on something without all specs accounted for.

 

I hate draging racing, I'm more into autox just to let you know. I went drag racing last night also. Your times look identical to mine
14.9 at 92.95mph 60 foot time was 2.308
88std hatch b16 with H/E, LSD, on 25psi faulken azenis, had my konis on full stiff in the rear and in the front also. my lunchbox weighs 2100lbs. I dont' know how some of you guys run low to mid 14's with these engines, but to all that do and to those trying to get their keep practicing, but you can find me at the autox course with my sticky hoosiers on

 

this thread is silly

all i gotta say is that with just MPH from a run cant give us an idea of whats wrong with ur car.
once u get the ***** to really admit the problems and post the whole timeslip, people might start listening to ya and threat you like a mature person

if u dont know how to launch or drive, accept it... and work with it and get better at it.. just dont start bitching at peoples response to u


IMO put the whole slip or STFU
trap speeds are affected by all aspects of drag aceleration.
humidity, tire pressure, tire compount, launch rpm, open or closed LSD, tranny gearing, shifting points, ignition timing, wheel weight, suspension setup, the power curve of the engine, weight of the car,clutch holding capability, DRIVER, track temperature, wind and air resistance, elevation etc etc etc

trap speed is just a RESULT of all of above...
get a book about HOW to drag race and u will see what i mean... ****.. even shallow or deep staging affects ET.......


Oh, and the statement about spinning half way down the track with high MPH is BS!!!!
i have spun the tires thru 2nd and my trap is way lower than when i hook them up, and i have even got before a 15.0 @ 95mph, and a 14.7 @ 91mph..... when i had a slipping clutch and i burned them soo much on 2nd that 3rd and 4th wouldnt hold


glad i am not a mod or i would lock this thing........

 

damn someone is heated.lol

 

Something must be wrong.

I was running 14.7's @ 91-92mph with 2.1-2.2 60's on street tire with an LS in my 91 crx si with a broken motor mount. ebay short ram and a thermal cat back.

Honestly I would say just keep going back and practicing it help's alot. When I first ran the car I was hitting 15.3's and 15.4's with 2.3-2.4 60's all day. I went to the track every week for acouple month's and my time's kept getting lower and lower.

Just check everything that everyone has mentioned and deff just work on your driving/launching skill's the time will come down.

actually driving can affect the mph alot like if you shift slow you will have a lower mph....once i missed 4th at the end of the track and ran a 14.5@91 compared to all my 14.4@96's.....all you need to do is PRACTICE.....60's are the key..every tenth off the 60 is a 2 tenths off your 1/4...btw cant you say your 60's there is nothing to be embarrased about....first time i went to the track i only got 2.5 60's. now im down to 2.2's. good luck getting everything right.

 

Maby it is my driving maby not ill know when I get to a dyno.
If it runs well on the dyno I willl admit it is my driving.
Next time I will get some slicks and see if it helps I did get a lot of wheelspin in first.
