Guest bastaad525 Posted August 19, 2004 Share Posted August 19, 2004 In my relentless search for dyno places close by... I'm kinda starting to run short on options I had REALLY wanted to stick with testing on Dynojet brand dyno's, to try to maintain some consistency and a good idea of what difference each upgrade was making. But I'm having a hard time finding one this time... Seems I can find plenty of places that are like 1 hour drive or more... but I've done that too many times already and really dont' feel like going all over SoCal just to get tested. I have some weird curse that every time I find a place close by and go to them 6 mos later they are out of business . However, I did find a place closeby that runs a dynapack dyno, the guy was cool on the phone, is offering a good price for a baseline, and will most likely have time to do it today. Did I mention that he's very close by? Always a plus . So here's the deal as explained to me. The dynapack dyno actually measures more directly, the hp at the crank before driveline losses... does that sound right to you guys? He mentioned to me that the rear tires are removed and some equipment hooked up to the rear drums or axles to get a measurement. He said it's much more consistent and accurate than a Dynojet... Sounds good to me. But here's my main question, how would a dynapacks numbers compare to a dynojets? Would they read higher or lower? Anyone know? If power is much higher or lower than expected, I want to know if it's a difference in the dyno, or just my car runnign that much better/worse. EDIT: well good news I guess... I remembered an article in Sport Compact Car not that long ago (last month actually) that discussed this very question... apparently Dynapacks do read just about the same as the dynojets do... very good news for me. So hopefully I can get an appointment there today and get my fuel tuned. If my last pulls were any indication I should be good for 220-230hp to the wheels and 280-290lb feet of torque Quote Link to comment Share on other sites More sharing options...
2126 Posted August 19, 2004 Share Posted August 19, 2004 A couple of point to consider.......every dyno (one shop to another)is going to read slightly different. Also, remember that the weather will make a differnce in "density altitude". This will effect the air desity. A cooler day will provide you with better results than a really hot day. Just remember that everything effects everything......always allow for variables. Just some food for thought! Quote Link to comment Share on other sites More sharing options...
