Nice #s. Install ur pulley and spacers and put up another dyno.

i've never looked at a dyno report before and never had one done, but if im reading that right, then it says you've got ~227 HP?

With all the mods you have on your car, I was figuring you would be close to 300 HP, since the Type S has 260 HP + Intake/Headers/Exhaust, that should almost add up to 300HP

so could somebody please explain what im missing here

stRodda

iTrader: (1)

i might eventually... but first i would have to buy the pulleys and spacers. but im happy for now.

actually, factoring in the massive auto drivetrain loss, it would be making around 300hp at the crank. dyno graphs show whp(wheel horsepower). a stock tl-s makes about 200whp... possible a little less sometimes.

vzuptnguyen

thats 227WHP, 227 HP at the wheel. HP is different from WHP.

vzuptnguyen

correct me if im wrong, but a TL-P has about 190WHP

fsttyms1

well there is flywheel hp and Wheel hp. Either way they are both HP. How they are measured is whats different

phipark

I believe it's closer to 170.

You need to figure in an almost 25% loss due to drivetrain on the automatic.

227 whp is not too shabby, btw.

type-s09

nice dyno, I have the same mods with different brands. I have the pullies and spacers also. I dynoed at 239whp and 201 f/lbs. You will be happy with the new mods!
ps:what gear did you dyno in?

stick

260HP is flywheel HP rating from the factory.
all HP ratings from the factory from any manufacturer is just that flywheel.

whp or hp to the wheels under load are what the engine really makes minus all other variables ie drivetrain loss, etc.

do u know what a stock TL S makes on that dyno?

edit: noticed ur in cali so this was on 91 cali piss correct?

of course dynos are just a tool to get a baseline for each modification. real world results would come from running the 1/4 mi and seeing what ur trap speed is.

stRodda

iTrader: (1)

they were all 3rd gear runs. btw, did you ever dyno before the pulleys/spacers? just wondering how much of a difference they make.

yup, my tank is full of calipiss, as you put it. and i have no idea what a stock tl makes on that specific dyno. ive heard from other people that the dyno i was on reads lower than others. but i figure having numbers that are slightly lower than actual, would be more acurate that some bullshit inflated ones.

Sorry- what were the BS #s?!?

Thanks for sharing the graph! Good read.

mr.motoring

Does anyone have a baseline graph for comparison?

The top end power has definitely improved and the torque powerband is pretty flat even before VTEC, but what about the low end, the throttle response must be good but was power sacrificed?

Also the power starts to drop off several hundred RPM before the 6900 RPM redline (though not any different from the stock 260HP @ 6100 RPM). I wonder if this is because the engine is not getting enough air in this area?

Anyway, great stats and your TL sounds like a monster!
Record us a video of you blasting thru a tunnel next time!

i was speaking hypothetically. ive just heard stories about 2 local dyno's that read differently. friend of mine had his car based at both shops and the results differed by about 3%. i took my car to the shop that read lower numbers. i just meant that i would rather have a lower, more conservation number instead of a graph reading 10whp over what it actually is.

i would like to see a stock graph. ive heard numbers, but ive never seen a graph. i would have liked to do a before/after run... but its not worth $60 to run twice.

i was also amazed at how flat the torque curve was. and smoothing was on zero... if i smoothed it out, it would look like a straight line.

one thing i noticed. the hp/tq lines crossed at about 5200... i always thought, whereever they cross, thats the optimal vtec crossover. if you draw an imaginary line from before vtec to where it is @5200... looks like the line would be straight. it wouldnt have the dip and instant jump when vtec engages.

and about it flattening out after 6k, i noticed that too. i wanted to try a run without the filter, see if it was choking the motor, but the car was all strapped down and i didnt wanna bother them with all that. but then again, maybe it just peaked out and was slowly dropping back down.



btw, just for the hell of it. i put the j32 up against my ex-accord. weight and gearing make a big difference. you can see the huge variance in power... but before the tl got the intake/exhaust, it lost to the accord on the freeway.

I always like your clips!!

i have a question for all you out there with more knowledge than myself.

i noticed that right after 6k, the power levels off... it doesnt peak and drop like all the other graphs ive seen. not to mention, mine levels off a little before 6 1/4... most of the peaks ive seen are being hit around 6.5. could the fact that im using a cleaned, yet used filter be hurting my highend?

im considering a couple things. gimme your input on which i should get.

1. new filter
2. new filter/velocity stack
3. test pipe & o2 terminator
4. smsp obd1 highflow cat & weld bung after cat/relocate sensor

something is choking the motor, cause the band is not supposed to flatten out like that. i definetly dont want to spend bigbucks on a obd2 highflow cat... so im unsure of what to do.

Rpappi

i could just be your car. not every car is the same.

stRodda

iTrader: (1)

yea true... its just that every n/a dyno ive seen reacts that way. rises, peaks and drops.

fsttyms1

You need to know what the af is also. I highly doubt the filter or any thing is choking the motor. Most likey its the ecu. Reset it before hand. Also like i said deed to find out the AF is to see what teh ecu is kinda doing. This is where a vafc or Emanage would be nice now to tune it. Also make sure that your 2nd stage actuator is working

stRodda

iTrader: (1)

im not really sure what the 2nd stage actuator is, but for example... when im driving, if i give it a little gas, it instantly gets noticably louder, while still in the same gear. is the actuator what causing that?

and about the vafc, ive read on here... and i believe that you might have said as well, that the vafc is useless. people have actually lost power from trying to tune with it.

etxxz

that's pretty nice. my '99 made 194 and that's with i/h/p and vafc but it was done in a very hot and humid day in s.FL so 227 sounds very realistic and i bet that thing is fast!

stRodda

iTrader: (1)

btw, the 2nd stage actuator is working. any other reason why my power levels off early like that?

gc86

Where did you get your car dyno'ed? and how much is it for each run? BTW very nice numbers, im hoping to be where your at after my header/exhaust install...

ChrisQ1980

Very nice, did the car get dyno'd when it was stock? If I recall correctly the average is about 205 to the wheels?

stRodda

iTrader: (1)

i ran the car at dnr in hayward. and no, i never ran it stock. i didnt want to spend money on dynoing a stock motor. i wasnt going to do baseruns after the mods either, but i figured, just to check to see if im at where i should be. anything in the 220's is good, so im happy.

gc86

How much did they charge you? they quoted me 85 bucks

etxxz

85bux an hour sounds about right...normally is like 85-100bux for 3 pulls. i've been quoted $175/hr of dynotuning lol

stRodda

iTrader: (1)

yea, $85 for 3 pulls.

gc86

Im about ready to see where im at before I put on a AFC NEO for my final mod. Will probably end up going to DNR too. As of right now I have XS Power Headers, AEM CAI, Magnaflow Hi-flow cat and a custom axleback exhaust with the stock b-pipe. Im hoping for around 230 but I think the stock b-pipe is holding me back, we'll see. This is on my 01 CL-S btw.

good luck, lemme know how it turns out.
