bogged the launch just a little...normal 1-2 shift powershift 2-3 3-4

12.470 @ 108.53 1.653 at 16psi first run before setting mbc
12.210 @ 112.45 1.698 at 21psi set mbc normal easy shifting, spun tires a little
11.950 @ 114.18 1.712 spun tires on laucn again, but powershifted 2-3 & 3-4
13.836 @ 109.78 2.212 spun AGAIN but tranny poped out of first gear!
not good
after this run I was real worried that Ihad possibly broken a driveline part
drive around pits...car seems fine.
I put the 4 gallons of 93 pump back into the tank
turned the boost down to 19psi
decide to make one last easy pass to confirm nothing broke and that the trans stays in gear.

so..i guess it's fine.
12.131 @ 113.77 with a 1.765


all the ususal...same mods as last week, with the addition of a spearco "drop in" FMIC core. The info on the logs shows that the FMIC core wasn't doing well. Intake temps after the intercooler are 5-15* hotter than with the stock FMIC from start to finish at the same boost level (within 1psi). It was colder ambient temp tonight than on sunday during the day last week. my data on all 4 runs leads me to belive i could have gone exactly the same if not better on the stock FMIc core.

 

Good run, 11s on such few mods is sweet.

 

Man nice runs, I am trapping the same thing 114 mph, but I just can't seem to hook!!
I might have to lower the tire pressure next time I go out. My 60 foots also need some work, believe it or not they were low 1.8. I usually get low 1.7 to high 1.6. I have to work on my launching or atleast try to control the wheel spin.

 

What can i say more??!!! u keep impressing me with yr tuning skills and yr car.

good run and fantastic time. keep it up.

 

Nice job, Nate! There is a lot more in it, though!

Keep up the good work!

 

Can you explain what you mean by "Powershifting" cause some people have different definitions

 

Leave the gas on the floor, but you still use the clutch.

You can set up a secondary, lower rev limiter (say, 6000RPM) that kicks in when you push in the clutch that works very well to smooth out power shifting. I feel it is even smoother than lifting since you don't get the jerk when you get back on the gas.

 

Damn... Good times man .

 

granted i am no racing guru or anything...but isn't that really bad for your motor....especially if you missed a gear?

 

so the intercooler stock intercooler is better?
who make a good aftermarket intercooler that makes some power?

 

Heck, it could be bad for the tranny(synchros),clutch, and transfer case. But you gotta pay to play. Going FAST is not cheap.

 

I used to miss a gear from time to time when I lifted to shift. But I haven't missed one since switching to no lift to shift. I think it is actually easier to shift this way, and you are less likely to make a mistake.

It isn't bad for the engine. The 6000RPM rev limit takes care of that.

If you did miss a shift, it is probably worse for the transmission than if you were lifting, but only slightly. That 6000RPM rev limit really does save you.

With the secondary rev limiter that kicks in if you even breathe on the clutch pedal, I think it is really quite safe to power shift. It is just like lifting (engine RPMs FALL with the clutch pedal in), but without the need to move your right foot.

 

I got some more tuning time with the evo last night

with the AEM's internal datalogger running the math for wheel hp...It was putting out about 340-345whp on the 114mph run at the dragstrip on 116 octane.

i have been able to tune it at 20psi of boost on 93 pumpgas to make 330hp with the same math settings and same weight. It meant taking out about 3* of timing but the lower timing allows more boost, so there's a big net power gain and less knock voltage.

so going to the track on sunday to try and make another 11 sec run on 93 pumpgas with the stock IC back on the car.

going to install injectors/pump soon, as Im hitting 97% duty cycle with this cold *** air.

 

I think most of the front mount intercooler kits are more for looks. Most of the gains probably come from less restrictive piping than the actual core.

 

Your motor could care less... It's you tranny that'll be pissed at you
