My winter project went to the dyno today for a little tune and make some pulls just to see what it would make. Well it was a little better than I thought it would be. Max on a Dynojet dyno was 348 hp and 368 lb feet of torque at 5800 rpm. I am very happy with this. I originally did a PCMforless tune, and it was just not where I thought the car should be. Just thought I would share it with you guys. There's not a lot of information available about the Comp 502, but for a stock headed car I am very impressed.

Are these SAE numbers? Your graph does not say. Torque seems high compared to the power considering your specs.

 

You know I don't know I'll have to call them and ask. I just looked at my print out and it doesn't say. I am going to have my wife scan it that way I can post the whole thing. They said the same thing, like it's running out of air, I plan on a tb upgrade, but that's down the road I've spent enough money on it for this year.

 

I've still got a flowmaster cat back that's probably not helping me out either, they mentioned that is costing me some power. And it could be the heads just won't flow and it's running out of air there too.

 

Not bad at all for stock heads and a mild cam like that! ...even if it is STD correction.
Tq seems right to me; it should be higher than hp for a relatively low rpm cam.

 

Thank you bowtienut, I really like the cam/car combo it is so much fun. I have so much torque in the mid range from a 20 punch in first the car pulls very hard. I figured a 330 number would be tops for this cam combo. I don't know a few things though, like how much of a difference the injectors made. My stock Multitec's were real loud and had low resistance on 5 of them. Yesterday was when I put the Bosch Gen 3's in and had it re flashed and put on the dyno. The car is much smoother all around at a idle and all over. I think my Multitec's were heading down hill fast.

 

I went by today and checked and yes, these are SAE numbers. Here's a copy of the whole sheet.

 

Rod., the dyno sheet says STD correction
Still...good numbers

 

you mean STD? That's pretty strong regardless... 325 ft lbs at 5700!

 

I figured they might be STD and depending on hum/temp, the numbers can vary a little or a lot compared to SAE. Just Call the shop and have them email you the dyno run file then you can download a free file viewer from dynojet and you will have access to all of the data. I am curious to see the SAE graph.

 

I see that now, I thought that had something to do with the smoothing. What exactly does it mean??? SAE or STD? So I can take a flash drive over and download the file and mess around with it on the Dynojet page?

 

Correction (SAE or STD or even STP) takes into account humidity, BAR and temps and provides a "corrected" number. This number allows someone who dynos under crappy conditions to have a useful number to compare to someone who dynos under better conditions. If you dyno under the most ideal conditions, usually SAE correction will bring the number down which is fine. If you dyno under the most crappy conditions, it may actually bring it up. Think of it as leveling the playing field for dyno runs.

STD is a non industry standard and tends to provide higher numbers which is typical of the ricers trying to impress folks with their four banger crap. SAE is the industry standard and what should ideally be posted and commented to. Most people post SAE here on the boards and we simply consider it the standard. Posting STD or even worse, uncorrected usually means someones just interested in posting high numbers. The SAE correction will likely bring your numbers down some but dont fret it.

Yes take a flashdrive over and load the file on it. They might even be able to email you the file. Download the viewer from Dynojet and create the SAE graph and post it.

 

Thank you wrd1972, I'll get it and see how it changes.

 

Update?

 

I'm a dead beat I've been working 6 12s for the last 3 weeks and then destroyed my clutch which I put a new ram powergrip on Sunday and so no I haven't had a chance to contact the tuner to get the info. I will though what I read though is there is a 2.7% difference between Standard and sae so that number should be something like 338 sae. But I intend to get it and see.

 

Wel if Missouri has been anything like Oklahoma this past week or two then it's been a hot (high 80s) and humid sucker outside.

 

Yes hot miserable for this time of year.
