hosser Posted October 13, 2004 Report Posted October 13, 2004 Anyone have numbers, or a pretty chart of an actuall dyno test on a 3.4l dohc? Quote
WhiteOut Posted October 13, 2004 Report Posted October 13, 2004 I know there's some on here somewhere. I recall seeing them a while back, but I couldn't even begin to tell you the name of the thread or who posted them though, and whether or not the links to the pictures still work will be another issue entirely.

DaveFromColorado Posted October 14, 2004 Report Posted October 14, 2004 damn, got a lot* of ignition noise in them dyno charts, either that or your tires are EXTREMELY out of balance .. in about a week, I'm gonna have a good write-up on the how-to's on manually locking your torque converter, and locking 2nd and 3rd gear for dyno runs. The problems with our cars is we'll hear a "dip" at about 90mph - that's actually the torque converter locking up - you'll notice it happens at about 5700 - 5800 rpm's on those dyno sheets where he get's his highest reading - it's a false reading because of the locking mechanism for the torque converter - I'd be willing to bet he's got a few more ponies under there that the dyno wasn't able to "sense" because of the converter being too "soft". --Dave.

Stealth Posted October 14, 2004 Report Posted October 14, 2004 it says 175hp 171torque or close to it Quote

Ill be intrested to see that, I had bunged dyno sheets as well thanks to that. Quote

I dunno what caused the erratic readings.... the "dip" you are referring to can be heard in this video. Quote
timg Posted October 15, 2004 Report Posted October 15, 2004 I have a few dyno charts from my car and a few I saved from other 3.4's for comparison. I can e-mail them to anyone who is interested. PM me on here. Tim Quote
Canada Posted October 15, 2004 Report Posted October 15, 2004 Here is a LQ1 5 speed, stock vs a custom chip...... Here is a copy of a dyno chart from Aaron Lephart comparing a stock chip to a Hypertech..... Quote
cryptnix Posted October 15, 2004 Report Posted October 15, 2004 i would show you but ... life isn't treating me well ... got a fractional T1 to my house to start hosting my web sites ... then this morning we lost power (about 50+ homes are out in my area) apparently they lost the neutral some place ... seriously, i think my next investment is some UPS' on everything chripes ... I woke up and all the FreeBSD, Linux driven machines were off but ... Windows machines were still running ... ok? But the BSD, Linux machines hold almost 200 gigs each so... no videos for you! The only reason why I think the Linux machines were off is because they have more hardware in them ... :-( I just hope to god I did not lose anything. I woke up to "unplug everything unplug everything ..." thanks to my dad screaming it. (he's an electrician...) but (just to get that off my sholders...) Quote
Vegeta Posted October 15, 2004 Report Posted October 15, 2004 I dont think that was a stock vs custom chip. That was the FFP chip vs him tuning it more for his car if I remember correctly. Quote
Vegeta Posted October 15, 2004 Report Posted October 15, 2004 michaels. Im not sure if thats the FFP chip or not on the first one but its definetly not stock vs what can be done, the spread is much greater than that. Quote
Brandon Posted October 16, 2004 Report Posted October 16, 2004 Can't find my charts off hand, but I had but car dyno'ed and came up with 163.8hp and 178.5ft-lbs of torque at the wheels. 1995 3.4L DOHC. Quote
DaveFromColorado Posted October 16, 2004 Report Posted October 16, 2004 sometime towards the begining of next month, I'm gonna get my Z on the dyno for sure, I'll have some STOCK numbers for everyone, on an auto, in 3rd gear, TC locked up, from about 1500 rpm's all the way to the limiter. --Dave.

timg Posted October 16, 2004 Report Posted October 16, 2004 179.3 hp and 168.7 lb-ft with an intake and exhaust. 12.5:1 a/f ratio >175 hp from 5700 rpm to redline at 6700 150 hp at 4700 rpm 125 hp at 4000 rpm 100 hp at 3400 >150 lb-ft from 3400 rpm to 6200 rpm >160 lb-ft from 3600 rpm to 5800 rpm Tim Quote
Guest TurboSedan Posted October 16, 2004 Report Posted October 16, 2004 Tim, where did you dyno your car? Quote
timg Posted October 16, 2004 Report Posted October 16, 2004 Tim, where did you dyno your car? http://www.dynopro.com It's near Denver. There's also a shop in Rapid City. Tim Quote
