Dyno Results In!

[crystal_SVT]

finally went to VMP tuning here in central Fl. an got 2 pulls. the 1st pull netted 277wrhp 275rwtq. then we let it cool for about 15 and the second pull made 279rwhp 275rwtq. :coolman: im pretty happy with the results considering its a 95,000 mi. motor and only power mods being JLT RAI and BBK Xpipe. heres a pic of the dyno sheet.. only problem was at about 5800 rpms the graph started fallin off and was kinda speratic. tuner said it may have somethin to do with IMRC's... give me your opinions on what could cause this.

thanx man

That drop off looks like it's ignition related and not the IMRCs. Probably the plug wires.

yea....i was going to say the same thing about the graph falling off....seems like your ignition. Replace plugs/wires in a while??

If you havnt already I would do, plugs, wires, fuel filter, and seafoam:thumbsup:

+1.

look at my sig. I have many more mods than you only put down 290/293 tuned. those are very nice numbers!!! If you change the above stuff, a few more ponies could be found too

Looks like its time for an IMRC delete and a short runner

thanx for all the input guys! as far as plug wires i have the cursed MSD's lol had them for about 2 yrs now. i was thinkin ignition possibly also... maybe its time for new wires.

also forgot to add the spark plugs are pretty much brand new autolight 764's gapped at .054 so there most likely fine. how would i go about testin coil packs as well?

 

[crystal_SVT]

anyone?

yes, thats what will be gettign done with mine tomarrow...


and nice numbers man, i should have mine on the dyno in a week or two.... i got some parts comming in:burnout:

 

[crystal_SVT]

thanx for the compliment, hope she pulls good numbers!

whats more likely to be bad the wires or coil packs?

 

[crystal_SVT]

jsut an update, i changed the plug wires today with oem motorcrafts and still feels like it has the same dieing off feeling at the same rpm as shown on the graph.. if it is ignition the only other logical option is coil packs as they are still the orginals. any comments on this?
