I now understand why my track times are horrific, (besides my 60' and launching needs lots of work).. the car shifts to 4th WAY before I get to finish the 1/4....

So I thought to myself, what if I didn't allow it to get to 4th on the 1/4? but that would require testing to see how fast the car could go before hitting redline in 3rd.

I didn't know how far D3 (or 3rd gear) on an auto could go MPH wise before hitting redline or 6800, so I took her on the freeway to see... did it twice and according to the tack I hit 7000 on the nose, but the AFC listed my highest rpm at 63??, damn the tack is WAY off at higher rpms... anyway I got up to 110mph in 3rd before I let go and shifted.... I expect WAY better times at the track next time now that I will keep the car in 3rd safetly just before the point of redline before finishing the 1/4...

 

Odd... i have an automatic b18b OBDI stock ecu ,.. and you can not just leave the shifter in 3rd and let it ride and it hit the fuel cut off like 1st & 2nd the ECU takes over shifting from 3rd->4th soo even if you leave it in 3rd it will shift into 4th for you ... hmmm play with it some more .. and listen for the shift back into 4th while you still have it in 3rd ... tell me what you come up with

 

You hit 15.9 at the track?!!?!?!?!


Damn, I just got my turbo back in my auto GS. I hope to run better times than that.

You have any problems with the tranny yet?

Dave

 

zilverz: I never heard of that, but thats odbI, I own a odbII car and I hit only a few hundred rpm shy of the rev limiter for an auto... I'm sure at the track I might bounce it once :/ well either way it should be an awesome experience.

 

I've been keeping up with your "turbo auto" experience..since i myself am an auto owner for now. I'm sorry but 15.9 with a turbo is a terrible time..taking into consideration a bad launch, being in D4, etc...you should be nowhere near 15.9. You should be running low 14's with that setup...I have a feeling it might be something other than that. I was reading somewhere about a "limiter" where the transmission won't transfer more than X amount of HP to the wheels..Im not sure if its BS or what anyone have any info?

 

maybe it is BS.

My brother went to pick up the car the other day and he could see the difference. We have a level 10 torque converter and a revhard stage two that was boosting about 9-10 LBS (because it was over boosting) and my brother said that it launched like a bat out of hell.

I remember driving the car when it was boosted 7 months ago and let me tell you - peeling the tires on a 50MPH downshift on an automatic without a torque converter requires a little more than 150 WPH.

I'll let you guys know when the car comes back, hopefully today.

Dave

 

PLEASE keep my posted on the levelten torque converter experience, difference because no one ever gets it, I've visited levelten but don't have the money for. I totally agree that my car should be a 14 second car, and I will see as soon as I can get to the track.

As for this "limiter, I have no idea, but I'll chech the helms manual about that when I get a chance, as far as I know the only thing like a limiter on an auto is a top speed limiter, which I believe is 125 or 126mph... the highest I ever took my car was 125 on the parkway a few years ago (my first race) and it was floored for a good minute and I never got higher then 125 on fairly flat road.....

I'm not sure what you mean about "considering bad launches and D4" dude I think my car was shifting from 3rd to 4th at the track at around 5000rpm and my trap was only 90mph.... if 3rd takes 110mph before hitting redline that proves my car was shifting 3rd ENTIRELY too quick... my theory on that is the tranny senses more power and wants to shift quicker because the power is higher then what its used to.... but 3rd gear pulls like a goddamn beast out of hell, its definatly the automatics strongest gear.

you sure its not your fuel problem ? and as for torque converter i've read that protorque torque converters are better than level 10's

 

Key here is "torque converter." I have yet to see an automatic integra with no tranny mods actually work correctly.

 

The point I was trying to make is no matter how bad your run was, your time should not be that high if the turbo is installed correctly/working/etc. Keep us posted on what you find out.

 

I have to agree with him. I had created a post about turbo automatics a long time ago and people said they ran 14 with 7 psi of boost. Something must be wrong.

 

Like I said I can garuntee 2 things, keeping it in 3rd through the whole run till net me a much higher trap speed as opposed to 90mph. Secondly my best launch or 60' was 2.734, auto tegs can get 2.6 or better 60's......... put these 2 together and I should definatly be running 14's next time I go, but don't worry I will keep you all posted. :D

 

Just a note: When I was talking about that peeling out on the highway, I did not have any torque converter in my car. It was a bone stock tranny.

About the torque converter - it is good if you want to stay auto. It will not help in holding boost, but it will help with your 1/4 mile times since it will give you a better launch and it will shift harder. I cannot objectively quantify the benifit of the torque converter because I got a whole new tranny, and a new engine at the time of the install. You know how that is - once you break the car, it never feels the same again. The only bad part about the torque converter is that you probably want to get another tranny cooler since they produce a lot of heat.

If you want to stay auto, get the torque converter. If you are going to go FI with the auto, get a fully built tranny from level10 ($1500) so that you can handle all that extra torque.

 

Not to make you look stupid or anything, but levelten does NOT sell complete trannys for import cars. I talked to them in person about all the options.

1. Get tranny cooler, bigger tranny fluid pump, and torque converter - $1400 give or take
2. PST kit - $900 give or take installed

Both these things are only add ons... just want to make it clear the prices and work I was quoted from the guy at levelten who took the time to talk to me for a good 2 hours when I visited.

 

Well, you did jackass. HAHAHHAHA... my bad for posting the wrong information.

To correct myself, there was a tranny that they sold ($1500 last time I checked) but I don't know if that meant you have to send your tranny to be rebuilt or they just give you a fresh new one.

In any case, I like level10. I would recommend the torque converter.

 

?? not from my experience ... do these two tests .. then tell me if you believe 3rd is the strongest

1) start in 1st ... shift to 2nd ... will driving in 2nd keep it under 3000rpm ....downshift into 1st and floor it

2) leave the shifter in 4th... start driving ... listen for the upshifts .. until you get to 4th.... keep it just under 2500RPMz in 4th ... downshift into 3rd and floor it ... it actually drops into 2nd

 

z you may be right, but when you have alot more power going to the wheels the shifting is considerably different. MY best example is on the highway.

Before turbo:
Flooring it on the highway at say around 60-70mph would get me second gear quickly, then a shift to 3rd which it would hold for a loooong time, then mabye hit 4th..

After turbo:
Doing the same flooring at the same speeds I only get 3rd gear for a brief moment and then a shift to 4th....

My conclusion on this is with a stock tranny it can sense the power output from the engine to the ground and shifts "safetly" not staying in a lower gear long unless your WOT, and even at WOT it shifts alot quicker...

I may be wrong about that 3rd gear being the strongest, but it does pull the longest, with turbo the car eats 1st and 2nd gear like a 400lb italian woman eats her breakfast...

 

s: i hear ya boss ... yea ..i forget your boostin ...my b18b is putting a decent amout of hp out 200hp-220hp range all motor ... i guess i cant really say about the turbo.... maybe since you dont build RPMz as quick in 3rd you are getting more out of your turbo

 

I drove around the car yesterday and I have a couple of questions for you guys with turbo autos:

HOW THE HELL DO YOU GET 2.5 sec 60ft times? I'm guessing mine is in the neighbrohood of 4 secs, at least it feels that way.

Still got a lot of work to do...

One other thing - when your blow off goes off, do you get a little "whine" at the end?

Dave

 

When at the track, floor the brake, and gas it till around 2000rpm... when its on the last yellow let go of the gas and floors it... its called powerbraking.. DO NOT DO TIHS FOR MORE THEN 2-3 SECONDS AT A TIME. its puts ALOT of stress and heat on the engine quickly.
