linky no worky

 

I had to cut & paste your webshots link in your sig to see the dyno printout (above link doesn't work). This one should link OK:

Dyno result link

I noticed on the graph, HP & TQ cross at like 4100 RPM? Every other dyno graph I've seen shows them crossing @ 5250. I think there is a number problem here someplace, and like w/ doctors, I'd get a second opinion from another dyno if possible.

 

they arent crossing at 5250 becaue the hp and tq scales are different.

 

Live for TAs- Thanks for fixing that link. Yea I think a second opinion is in order here. From all the dyno runs I saw that day, I
noticed that none cross at that magic point of 5250. I think I'll contact AAM and see whats up on these runs.

 

I've never seen ANY Hotcam car put out that amount of torque unless you're using N20. The hp is right on the money though.

 

I am stopping by the dyno place on my way home today and see what the deal is on the run. I'll post back what their explaination is.

 

You don't possibly think he was referring to a Z06 Vette do you?

 

Exactly. I think when the guy was printing out your results he somehow got the scales mixed up. If you went by the HP scale on the left and then look at the TQ based on that scale TQ would be almost the same as the HP, somewhere around 335-340 which be right on for your mods. That would be almost the same numbers my car put down through the full exhaust with the HC kit, 341rwhp/337rwtq. He also only plotted your RPM's out to 5200 for some reason. I would see if he can correct your graph and reprint a copy for you. Here's the Dyno sheet from my last two runs. The higher numbers are through the ORP/cutout.

 

Look at the RPM axis. Your hitting peak torque at 3800 rpm and peak hp at 5000 rpm. That is about 1000 rpm off. Your cam should peak around 4500 and hp around 5900. If you keep your HP curve but add 1000 rpm to your speed axis, it looks about right. If you then calculate torque from this, you get a more realistic value. Peak torque drops to about 325 at 4800 rpm.

My guess is that he read engine speed incorrectly from your car. Why would he run it to only 5000?

 

HP is about right.. I am suprise at the torque.. good job!
sweet numbers
