This was done yesterday. I was dissapointed by the max hp number; I was expecting atleast 165whp. This engine compression tested 215±03 psi three weeks ago, so it's a healthy engine. So, please tell me what you think.

 

wow youre very low on tq......maybe this dyno reads a bit low....

and the hp is low, but you should be able to free some good hp up with the easy bolt ons....

 

It is low IMO for 5-speed.

 

wow that does seem a little low

 

damn i thought ludes came stock with a little bit more whp and wtq then that?

Check out others' dyno

 

Thanks, I thought the numbers were on the low side. When I approached the computer after the runs I saw 168 whp on the screen, then a different screen popped up showing 158 whp. He then proceeded to try to sell me a fuel management system since the car ran lean and the v-attack power spike. It just occured to me, I should have caught this earlier, the 12.X:1 air to fuel ratio is not lean, but rich; that guy had no idea what he was talking about. I feel retarded for blindly following what he said.

So maybe he was looking at someone else's run, or maybe he pulled a different one up to give to me, or somehow changed the plots (unlikely, but you never know). I should have asked him, but I was freezing and had other things to do.

I'm not a pro tuner or very knowledgable (yet hehe) , but 12.X:1 is what i normally hear people typically tuning for. depending on how high that X number is it might be lean.

What are you talking about? Is it air/fuel ratio? Stoich is 14.7:1. Lower than this number is richer, higher is leaner.

12.X:1 is frequently a goal for turbo'ed cars, rarely for N/A cars.

 

^ that explains a lot. i dont look at n/a cars.

 

first time my car was dynoed, it did 160 with i/h/e VAFC, did more tuning runs, with the VAFC, ran 165...took all that out, put in a fields SFC, fuel all left at stock, ran 170 on the same dyno, with i/h/e

 

Freezing? I dont know too much, but dont people usually pull better numbers when the temp is lower.

Edit: Forgot not CAI

Buhahahaha! I'd like to see someone tune to Stoich and how long before it detonates.

N/A motors usually respond well around the upper 12's to mid 13:1 range. I personally wouldn't go any leaner since pump gas octane can vary slightly from every gas station, I'd like to keep a good cushion for lean conditions.

 

Stock Type SH's dyno at 154 ( depending on the dyno of course. This is according to the AEM dyno done at R&D Dyno in Gardena CA.)

so 160's for a base model bone stock sounds about right.

Really? I was going to say it seemed low but... My H22a put down 180 to the wheels with intake, exhaust, light weight flywheel, and no PS or AC.

 

Well then, if stock sh's dyno at 154, then 158 isn't bad. I just remembered that the guy who drove the car in backed it up to the dyno as if it was rear wheel drive. I wonder if I should patronize this shop again?

And upper 12s, lower 13s is a good range for n/a cars measured at the exhaust outlet? Also, would this number differ if I measured directly behind the cat instead of at the outlet?

Thanks gentlemen.

 

Remeber this is according to the dyno at R&D Dyno which i believe is a dynojet. i havent been there in months so i dont quite remember. Each dyno will vary (mechanically and temp and air conditions etc..)

180 whp on what type of dyno ? and are you in a civic spinning 15 inch wheels ?

Car-car motor-motor dyno-dyno all numbers will be significanty different. Its meant to be used as a tuning tool. Now that you have your baseline you have a good starting point.

 

Yeah, my runs were on a dynojet. Shouldn't the numbers from one dynojet to another be similar, assuming both are accuratly calibrated, regardless of air temp, humidity, full moon, migratory patterns, since it gives sae corrected numbers? This is assuming that it gives sae corrected numbers since the sheet has a sae correction factoer listed. Please correct me if I am wrong, I'm pretty new to this stuff. Thanks.

It's a 97 Teg spinning 15" wheels

 

well there u have it. Hes got a freak motor ( USDM JDM ? ) he dont count.


Even with the SAE corrected number air temp,altitude, fresh oil change or not and the history of the motor are not on the SAE chart. Anywho, looks fine to me. Just build away.

 

how many miles is on the engine?

 

Mine is a JDM motor, so that is some of the diff. Also, being in a Teg with no PS or AC and the lightweight flywheel put more power to the ground.

I think this guy is running totally stock right? So he is pretty right on. And like already mentioned, his conditions may have been drastically diff.

 

Yup, the engine is completly stock, 113K miles.

What does the SAE correction correct for if not atmospheric conditions (air temp, humidity, etc)?

That makes sense, since JDM H22s got the true 200hp. Still, a pretty strong motor...
