What shoud the #'s be? (Data loging)

Post by Charlie » Mon Sep 17, 2007 10:34 pm

Short burst @ WOT. My readings....

ECT.....182 Deg.
IAT......112 Deg.
Load.....1.322113 <----- Don't have a clue if this is right.
MAF......3.79394 Volts <--- Good? Bad? OK?
RPM.......4590
Timing... 16.25 <------ Low?
TPS.......4.25 Volts <----- Is this right @ WOT?
MPH.......65.42383

AFR was bouncing between 11.7 and 12.7 No pinging, knocking, clattering
Boost right at 14 psi (Heaton)
This is just a snap shot before I let out of the throttle. And to be honest, I'm not sure if I was all the way to the floor yet.

It took 5 sec to go from 20 MPH to 65 MPH (Rolling into the throttle just enough not to spin)

What do you think?

I'm thinking I need to get the timing a little higher... Without leaning out.

Any advice / help / pointers, would be greatly appreciated!

Thanks
Charlie

It's a Lightning...

Charlie, those numbers look fairly correct for what it is that you were doing.

Ryan.... I wish you had not said that. The best I can get in the 1/8th mile is 8.00 @ 88 MPH 1.88 60 foot

And with this mod list, I would think it should be faster.

My mods.

355 gears , NO stall converter, stock exhaust.

Built bottom end.

slapper bars (yeah I know)

And a few other thing I may have left out.

Yeah I have some money in it, and I've been up past midnight every night since FFW in Ennis looking on the net, trying to figure out how to get more out of it.

Charlie,

With your mods your 60 ft times should be down in the low or mid 1.7XX.

Might be some tranny issues going on. A couple years ago my tanny was going south due to my converter ballooning. My 60 foot times continued to rise even though I increased mods. Turned out the swelling converter was pushing components around that eventually came loose and started to eat other internal parts. What finally brought this to the forefront was on a normal take off I hit the gas hard and it felt like I was doing a burn out but no marks on the street. The converter was just spinning but the interal damage would not let the clutch plates catch.

After the tranny was torn apart the loose pieces were faling out and the plates were heavily scored from the loose parts. What a mess. I was within weeks of a full tranny failure according to my tranny re-builder.
