my dyno numbers at 3 psi, lol
 

haha, well i dynoed her today... was only at 3 psi. put down 180.1hp and 206.5tq. theres a 22% drivetran loss through my 4t40e tranny which puts me at 220hp on 3 lbs of boost. not ------ bad at all for 3 psi! cant wait til i get my s-afc and even bigger injectors and run 10-12 psi. :)

Re:my dyno numbers at 3 psi, lol
 

wow, this may just be the dumbest thing I've ever heard. do you get free dyno time or are you just rich? sorry I sound like I hate you, it's late and I'm tired.

Re:my dyno numbers at 3 psi, lol
 

no, actually i wasted 145 bucks on that ---- too. i went not for the numbers, but the wideband. i was hopeing to up it to bout 7 or 10 today, but that didnt work. turns out my injectors arent as large as thought, so that held me back. so now i have to find some larger injectors and get an s-afc, get rid of the fmu and inline pump and hit the dyno agian. then i should be good to go.

Re:my dyno numbers at 3 psi, lol
 

Where did you go? Dynotech?

Re:my dyno numbers at 3 psi, lol
 

very impressive 8)

Re:my dyno numbers at 3 psi, lol
 

who told you 22% drivetrain loss?? That's just adding hope to those dyno numbers. What can it do in the 1/4?

Re:my dyno numbers at 3 psi, lol
 

honda_joe- no, dynotech sold their dyno and are in the process of building another 2. it will be about 2 weeks until they are up and running and i couldnt wait that long. i went to big shots in hudson.

dewme5- the 22% loss is damn near exact for the tranny i have. they rate my car at 150hp stock at the crank. ive done a lot of research, and every stock auto with my tranny i came across dynoed at 118-119 at the wheels. that equates to a 22% drivetran loss. theres where i get that number from...actualy tests, not just a guess. :P

Re:my dyno numbers at 3 psi, lol
 

Your car is auto!!! WTF the two J-body guys on this site are auto, whats with you guys? lol

Hopefully your cooling that shitty planetary gear system down ;D

Re:my dyno numbers at 3 psi, lol
 

3 buddy =) and mines a MANUAL!!! lol. Not turbo yet though :( In the mist of buying my t3/t4. Nice numbers dude.

Re:my dyno numbers at 3 psi, lol
 

well hello there brandon.

Re:my dyno numbers at 3 psi, lol
 

ok first of all what year of car and what year of engine
cause that doesnt look anything like a 2.4 newer ecotsk motor that could use 3 lbs of boost and gain that much and by the way not puting you down or anything well you must have alot of money and time on your hand , 1 year to do all that i have had a year on my 94 civic and with just the engine swap and the turbo install it took me that long...

Re:my dyno numbers at 3 psi, lol
 

few things threshold... thats not an ecotec. its a 2.4L...also known as an ld9. its whats in a z24. ld9 was from 96-02. ecotec was from 02+. the ecotec motor is only a 2.2L and its been proven a few times that it still cannot make as much power as the ld9 with the same mods. it can suppost more power in the end, but it does get as large of gains off of the same mods. this motor is still more powerful. the ecotec wouldnt gain 50-55hp at the wheels off of 3lbs of boost. it doesnt look like the "2.4 newer ecotsk motor" because there is no such thing. they were 2.2L. also, if you know what a standard 2.4L looks like, then mine still wont quite look the same, i have a differnt intake manifold on mine now. for the time and money issue, actually, it took me about 3 months to do the turbo workin maybe a 2 or 3 days a week for about 2-3 hours a day with many small things holding me back and taking up time. i started buying parts one by one since the beginning of last summer. once i had them all, i started putting it on over this winter. the engine is the only thing i did this winter, its not like i did all the body work and all in that time as well.

Re:my dyno numbers at 3 psi, lol
 

Damn those are some pretty good numbers for a LD9 :o
Congrats.
BigJ he is probably smart having an auto for the LD9 the manuals sucked huge ass. I went through about 4 in about a year and a half and a buddy of mine went through 6 in about the same time, he just gave up and let the bank take the car back. I am now parting mine out :-\

Re:my dyno numbers at 3 psi, lol
 

you are an idiot.... jesus christ. Do some homework on a cavalier before u start talkin ---- and if u don't care to do the homework, plz don't post ur arrogant comments.

Those numbers ROCK FOR ANY CAR. 3 psi is like nothing.

p.s no one cares how long ur project took.

Re:my dyno numbers at 3 psi, lol
 

whats the stock hp on your car without the turbo. 3 psi and your making like 180 hp?

Re:my dyno numbers at 3 psi, lol
 

stock horsepower rating is 150 to the crank with equal torque. most autos dyno 120 to the wheels while manuals may dyno 130-135.

Re:my dyno numbers at 3 psi, lol
 

damn son that pretty good at 3 psi...now crank it up to 20 and see how things go ;D

Re:my dyno numbers at 3 psi, lol
 

i need to see a sheet. i dont believe you. thats like 25 hp per lb of boost. = gay

Re:my dyno numbers at 3 psi, lol
 

i second that

Re:my dyno numbers at 3 psi, lol
 

I know that what im saying. i call bs. are you saying 180 to the wheels? 3 psi wouldn't give you that much

Re:my dyno numbers at 3 psi, lol
 

yea that sounds pretty unbelievable to me that you go from 120whp to 180whp with only 3psi of boost. I'm not calling you a liar, but i would like to see some dyno sheets ;).

Re:my dyno numbers at 3 psi, lol
 

I think your boost gauge is broken. ;D

Re:my dyno numbers at 3 psi, lol
 

ya ya the ecotec makes less power but I bet it doesnt throw rod bearings like my friends 99 Z24 (ld9).

He has had the motor either rebuilt or replaced 6 times in 1.5 years (all warranty). 3rd actual block, 2 rebuils PER block and they end up knockin. This newest motor is a newer one i think and it's lasted 10k so far. BTW he doesnt drive like an ass. and the 3rd time the motor didnt spin a rod bearing sorry, it CRACKED THE CRANK IN HALF!

But ya, they have nice power, when they work ;)

Re:my dyno numbers at 3 psi, lol
 

Cmon guys, this is 2.4 It doesnt take much boost to see some good gains. A 60whp gain does seem like a bit much, 4-5psi seems more likely.
Good #'s on lowboost anyway you cut it.
mmmm, torque.

Re:my dyno numbers at 3 psi, lol
 

most people forget about the Huge Displacement. Our engines are big blocks compared to ur Honda 1.6's. Plus a t3/t04e is not that small of a turbo hehe.

Re:my dyno numbers at 3 psi, lol
 

stock specs are 150hp, 155tq at the crank. 120ish at wheels. yeah, i dont blame you guys for not believeing me. i bout ---- my pants when those number came up. bosot gauge does work correctly though, ive checked the line many times and even swapped in other boost gauges, and they read the exact same thing mine was. the turbo isnt all i have done, but its the major thing. id say if you count in the other ----, and a stock auto dynos at 118-119, so if i figure in maybe 5-10 for the other ---- done (prob not even near that though), thats 125-130 at wheels.. that would equate to a 50-55hp gain at the wheels resulting in 16.7-18.3 gain per lb of boost. i though that was insain too, but the gauge is accurate and thats what the dyno came up with and damn near to every other pull. ill check to see if my scanner is working, hopefully it is. ill get the graph up in a few min. assuming my scanner is working.

Re:my dyno numbers at 3 psi, lol
 

sweet, scanner works :) here for you bastards that think id make it up:
http://www.shownglow.com/dyno_4-10-03_3psi.JPG
for those wondering why theres no power up til 4100rpm, thats because the way he drove it was hed drive it normal through first and second. shifted into third, got to like 50 or 70 mph (dont remember which, floor it (my tourqe converter looks up around 3.5-4 grand when you suddenly floor it) then took it to 105mph and shut it down which was always around bout 6300ish rpm (redline is 6500) but yeah, so there ya go for you nonbelievers. :P

Re:my dyno numbers at 3 psi, lol
 

First of all, chassis dynos can be such bullshit sometimes if you apply the right (wrong) correction factors and calibration. Second of all, let me assure you that drivetrain loss is NOT a fixed percentage, not even close because there are some fixed losses, that are not really proportional to the power you're making.
A powerful car will have a less percentage drivetrain loss than a low power car with the same drivetrain.

Re:my dyno numbers at 3 psi, lol
 

i think i stand corrected but i still have a hard time trusting that. I mean i'll beleive it if it were like 5 or 6 psi but only 3?? you have like 155 horsepower(auto)so your making like around 130-120 wheel horsepower. I might believe your probably making 180 hp not wheel horsepower. I dont know its just weird :-\

Re:my dyno numbers at 3 psi, lol
 

Matt,

Nice numbers i'd have to say myself they seem way high for 3 psi on our engines. Your car was never a freak that i was aware of like some others....

I still think something is up with your gauge (i know you tried another one) but maybe its not getting the correct reading. I seriosuly think your running more pressure than that because you said you even clipped your injectors. Injectors shouldnt slip at 3 psi...... at least i woudlnt think so.

Still nice numbers, i too just happen to doubt the actual psi your running regardless of what the gauge is showing.

Re:my dyno numbers at 3 psi, lol
 

no, they were clipping at anything higher than 3 because the fmu would push the fuel pressure up to 80+ then and which point they would clip.. it wasnt the turbo making the clip..thats not related, it was the relly high fuel pressure doing it from the fmu. i agree though, the numbers do seem pretty damn high for 3 lbs...but hey, whatever, im not complaining, lol

Re:my dyno numbers at 3 psi, lol
 

is that a safe a/f ratio?

Re:my dyno numbers at 3 psi, lol
 

yes its ok.

also you guys gotta remember its not PSI that makes power it's CFM and that turbo (t3/t04e) will push alot of air. The 2.4 is a big motor and would consume that much volume of air. I'd say those are around where it should be.

Re:my dyno numbers at 3 psi, lol
 

The HO intake manifold, throttle body, and pullies would make quite a big difference, did you swap in the HO cams too? On JBO a while ago there was a post about a guy making 20whp with those cams. He dynoed before and after to see what the difference was.

Re:my dyno numbers at 3 psi, lol
 

nope, the cams arent in. im still not sure if ill do them or not. a lot of guys said they didnt gain anything and most lost a good amount of torque. also, the pulley isnt on either...its just sitting in my garage. alls i have on it that are HO are the injectors (getting replaced with much larger ones today or tomarrow) , the mani and throttle. i think my port job wasnt perfect on the mani to head because it seemed to make me about a thenth slower at the track after i did it. and keep in mind, im auto, so im pretty much always consistant. the only diff i noticed form the mani and t/b was my top end started to scream. engine totally changed pitches at 5.5k and up since then. but track times were a tenth slower...

ohh yeah, and for the a/f ratio. under boost it was bout a 13 in that run. most others i got it tweeked to bout a 12.6-12.9ish area most of the time. when it wasnt in boost at all and was being driven normal, the af on there shows like a 15 i think. id have to go back at look through the tables, but i believe thats areound a 15. stoich on a n/a motor is 14.7, so that seems bout right to me since it wasnt in boost and preatty much running off factory settings.

Re:my dyno numbers at 3 psi, lol
 

Re:my dyno numbers at 3 psi, lol
 

Air volume has nothing to do with it, it's air mass that makes power! Air volume varies by temperature, so flow 500CFM at 100°C and that's not nearly as much air as 500CFM at 20°C. CFM is invalid when talking about turbochargers, hence all compressor maps have lb/min or kg/min and never CFM.

Re:my dyno numbers at 3 psi, lol
 

the boost gauge works! lol, ive tried other ones and they all read the exact same thing. remember, it is a larger engine and turbo than most of you are used to, so itsgunna make a lil more power. ::)

Re:my dyno numbers at 3 psi, lol
 

Dam, thats a flat A/F for a rising rate. It looks to be in the 13's, which I bet is fine for a lower C/R engine. What is the C/R anyways?

Re:my dyno numbers at 3 psi, lol
 

Compression is around 9.5:1.

Ive seen some crazy numbers from these motors, and i believe his. His arent that far fetched. If you do it right, the LD9 responds very well to boost. Most people only running 5-6 psi maximum are happy.
