Went to dyno for first time today to get a baseline before I started changing parts. My car is a 2000 ITR with 29K miles. My only mods are an aem cai, which I hate, and a POS magnaflow muffler on the stock cat back, which I also hate. I would post the chart, but I have no scanner, so....

hp tq
3k 50 90
3.5 62 95
4k 70 93
4.5 77 92
5k 85 90
5.5 95 92
5.7 95 89 vtec x over
6k 112 98
6.5 127 104 peak tq
7k 138 104
7.3 147 103 peak hp
7.5 140 100
8k 140 95

I don't know if that means anything, but it seems fine, except about 15 hp down across the run. It was a 60 degree day and the run was on a dynojet 240. I read this thread https://honda-tech.com/zerothread?id=114617&page=2 and am going to try all the stuff in there. Do these numbers sound low to the rest of you? should I get my engine sorted, up to par and back on the dyno before I try to put in cams/header and cat/anything else like that, Or should I just change plugs/wires/cap/fuel filter and assume these are the cause of my sick engine, and continue on my quest. My goals for the car are to hit 190 with spec a's, type one/sms header and vafc(for now). It looks like I got a lot of work cut out.

 

that seems way to low, are you sure the dyno has been calibrated in the last couple years, also have any of your friends with stock R's, or and b-series for that matter, run on it. Remember a dyno is for tunning purposes not to get comparable HP numbers.

take it to another dyno, like if your car is sick get a second opinion, but this time go to a place where others have dynoed similar setups

im sure that your car makes just as much HP as the rest of the stock R out, not almost 20hp less

--------------------------m

 

Those numbers are VERY low. Try another dyno. If you get the same results, you need to get your car checked. Plugged exhaust or cat maybe...

 

just race a car a stock R should be able to take.......

I've been asking around about the shop and the dyno, and appearently the dyno is nearly brand new and fairly accurate. I saw a plot for a 99gsr off the same dyno last week and he hit 149...I think I'm basicaly being nickled and dimed to death. I'm going to replace spark plugs, wires, distributer cap and rotor, fuel filter and adjust valves and try another dyno later this week. If I'm still low then, I think I'll turn my car into a bon-fire and roast marshmellows.

 

I hope it works out

 

The first thing I would do is leak down and compression test. If your numbers are that low, then maybe your pistons rings are shot.

 

thank you...I did the wires, fuel filter and valves today, plus when I took out the plugs...ugh platinum fours. The initial butt dyno is pleased, I'm waiting for the better calibrated, less subjective dyno (wifey) to get home from class before I get too excited.
Btw...does anyone have a plot that roughly matches my mods they could either post or email me so I can see how far off I was?

technic were do you dyno? I need to do a baseline run before my cam install this summer.

 

abacus, in va beach...363-8878 chill baby,

 

and this is the first time you dynoed (sp) your car there? I don't wanna waste my money and get incorrect reading like you.

 

?yup first time...but I definately think it is my car and not the dyno, all those guys at millennium tune on that dyno, and they're numbers all make sense. Who else has a dyno around here

 

Here is what a stock 2000 ITR should put out.. First run is at 10 degrees and then 18 degrees timing.

Thanks...that actually mader me feel a lot better...Maybe I did get a F**ed up run...my plot look almost exactly like that but consistently 12-13 hp lowere every where....For people with a lot of dynojet expirence, is there something that could have been lined up wrong or set wrong that would make my run indicate low like that?

 

What was the correction factor on the run?

 

(sensing that I'm about to feel like an ***) I have no Idea...when I got the chart it was listed as sae power and sae torque, so I didn't worry about it. I really don't know a lot about this...I knew I would want to know the approx temp and that was about it. I even tried to rembember all my honda-tech learnings and ask all the important questions...but that one I didn't think about till you asked. I suck.

 

I thought you gain HP when you go to 18 degrees....

 

look at the dyno chart and how the runs are labled, not in the order they are listed, you will see how important timing is

 

those **** at millennium could not tune a radio........
but to get back to the post, I would check the correction factor.

 

Maybe too much of your Meguirs tire glaze got on the wheels and dyno rollers = no traction?

 

what color run was done with 18 deg. timing ???????????????????????

 

Yes, I'd like to know that too.

 

Is the blue one 18 degrees timing?

 

just take some time and read the graph,

he said his first run was done at 10deg, so the first must be Dyno run 2,

his 18deg timing must be the one performed after the 1st, hence Dyno run 4.

so the Blue line being Dyno run 4 must be 18deg

and the red being dyno run 2 must be 10deg

anyone else needs help understanding th graph, I will be more then happy to offer my services for $20 an hour

 

bumped the teg out to 18 today...hleped a lot below 6, but vtec doesn't have the same "holy sh@t" it used to. Back to 16 tomorrow.
