Here are the set up:
-J's Racing balanced JDM ITR engine 11.1CR (Thanks BPT for getting me this engine, I thought I just ordered a STOCK ITR engine )
-Custom BPT CAI Intake
-Spoon TB
-Spoon header
-custom resonated test pipe
-Kakimoto R catback exhaust (60mm, NOT the 70mm one)
-UR pulley
-Hondata Stage 2 (Thanks SgT for the base map and Garage 5 for the street tune)
-Hondata IM gasket
-290cc injector



Bottom line is the baseline run
Middle line is with ground wire kit installed
Top line is with a set of NEW NGK Power Cable to replace the old set (4yrs old) + the ground wires kit installed



Blue and Green lines are the baseline and the ground wire installed as in the last graph.
Red line is with ground wire, new NGK Power Cable, and To Fit (some Taiwan made line that used to wrap around the fuel line) installed.

Here is the AF ratio on the first and last run of the day.



Here are some notes for the dyno plot:

- 2-3 dyno runs were made after each modification and the highest runs were used.
- All runs were done on 4th gear
- The first and last run were done within 2 hours of each other
- The same dyno dynoed a BONE STOCK ITR at 166whp and a BONE STOCK RSX-S at 170whp
- All number are SAE Corrected WHP. I think the CF is around 1.1, high elevation SUCK!!

All suggestion on what I can do next to get more power is welcome!! I will probably replaced the little dented Spoon header and get a 2.5 inch exhaust.

nice

 

r u from alberta, is that pe's dyno?

 

200 WHP +
am i reading this correctly

Dynapack does not read horsepower to the wheels but rather to the hub. The wheels are removed when dynoing.

 

Yes, baseline was at 202whp, and the final run was at 206.9whp.

I know ppl are saying that dynopack gave higher whp reading than dynojet. But a stock ITR put down 166whp on the same dyno, which I think is normal.

 

BTW, the number on the graphs are not all accurate, so here is the summary:

Baseline - Js Racing balanced JDM ITR engine with the mods listed in the first post - 202.x whp

Groundwire set installed - 203.x whp

New NGK Power Cable installed to replace the old set - 205.x whp

To Fit installed - 206.9 whp

The dyno is done on a dynopack that dyno stock ITR at 166whp and stock RSX-S at 170whp earlier.

 

what is NGK Power Cable and what is To Fit ?????

Power Cables are the NGK plug wires sold in Japan

 

have SGT take a look at your fuel map. he should be able to get rid of the torque dip at vtec by looking at your A/F ratio. with that you will see a much flatter torque curve and better midrange power.
was the motor a stock JDM motor and you put in CTR pistons and had it balanced?

 

Hey Matt....time to show me that low 14....high 13 timeslip right?

Thats not a DIP, thats the fall of the CAI HUMP.


Side note: I put down 155-160 on a dynapack, and then 175-180 on a dynojet.

 

I haven't got any chance to tune the Hondata on a dyno yet, may be I will do it next time. Right now the VTEC is set at 5300rpm, the power feel very smooth all the way up to 8500rpm.

Tell you the truth, I don't know what's in the engine. All I did was ordered a STOCK JDM ITR longblock, and I don't even know it is a J's Racing balanced engine until I got my car back. What a big surprise!!

SgT, will you be coming to Vancouver and Western Canada for some tuning?

I know someone will ask what is To Fit, hahah. I will take some pictures the next few days and post it. From the dyno, it showed that the To Fit actually more power gain than the groundwire kit and the Power Cable.

 

You have the TCF set to 1.1 instead of 1.0. Doesn't that mean its giving a higher correction factor? So it's displaying numbers slightly higher than if it was at 1.0?

I could have sworn you thought it was a "SPOON" prepped engine a while back when you were posting about buying the engine from your local place which got it from Hong Kong? So which is it? spoon or j's? lol

You are right, but the Spoon balanced engine that I had was the old engine. It was always burning oil and having a lot of other problems, so I sold it and got another new engine. That's why I have the J's Racing engine this time.

The 1.1 is the SAE correction factor from the dyno due to the high elevation at the area I dynoed. So the numbers are the SAE corrected number. The non-corrected number was around 180+whp.

 

i hit 173.2 stock on that dyno with a aem and after tuning with vafc i made 179.6 hp with a 5000 x-over point..

 

ot is is pe tuning haha, which car do you have?

Here is a picture of To Fit.

 

Isn't that the "ionic" fuel tuning rubber band gizmo?

 

kengs, something like that!! Top Fuel have something similar too.
