For your nitrous run I hope you set your smarty on power level 8 and in the adjustment menu rail pressure 4, timing 0, and tq management at 4

It's real important to retard the timing as much as possible if your using nitrous

omaharam

Kind of what I was thinking. 50hp isn't going to probably show in 1/8th mile. You need to see what the big end of the track is like.

What were your trap speed comparisons by the way. You didn't show an improvement in e.t., but how did the speed compare?

Bill is NOT running the race tune

first run: Second run:
Tq=4 TQ=4
RP=4 RP=4
sw#9 Sw#8
Timing=2 timing=3
ET=8.01 ET=8.52
60'=1.895 60'=2.04
MPH=87.7 MPH=84.7

Third run: Nitrous Fourth run: Nitrous
Tq=4 TQ=4
RP=4 RP=4
SW#8 SW=9
Timing=2 Timing=3
ET=7.95 ET=7.82
60'=1.886 60'=1.876
MPH=88.4 MPH=89.6

Fifth run:
TQ=4
RP=4
SW#9
Timing=4
ET=8.14
60'=1.997
MPH=87.0

I noticed that 4 gave me the most timing rattle.

Let me know if you see something funny in my tuning, im not a pro by any means..

Hey bob, does this look about right to you? How big of a difference is this tune i have now from the 4.2 i was running before? am i just missing something from my setup to make it quicker than the 4.2?

Billm2004

the first race was a SRT cherokee. beat him by a half a second. the rest of the night i was battleing it out with a mega cab with more dont than me. the guy didnt speak english but i took a look under the hood and i saw off the bat, dual cp3's, intercooler, big turbo, mp8, nitrous, and i was able to get him to say injectors and transmission.

the mega was sick..the guy didnt speak english but i took a peek under the hood and off th ebat i saw dual cp3's, big turbo, mp-8, nitrous, intercooler, and i was able to make out injectors and transmission from the broken english.

Sweet video!

What was the Mega running?

IF you didn't have tons of smoke before Nitrous it won't make any difference with it....Your problem is traction...even in 4wd those tires won't stick a ton of power. What tire pressure were you running. If you didn't have the race tune like Bob states then you will be short of hp... KS

nice runs!!!

Billm2004

there was one run i had that still made smoke over halfway down the track, but i had too much timing to run the no2. i dont have problem with traction, i dont spin but my tire pressure was down to about 38 psi. i think thats some of the problem, my tire pressure was up more with the 4.2 tune and i had less fuel too.

Bill you must be from Texas. That sounds a lot like a guy named Ramario who I think is from the Austin area. Was the Mega a 2wd, Bling wheels, and 6 speed manual? He makes pretty big power but I don't know how he gets traction with the 2wd....if this is the same guy. Nice guy...def. hard to understand his broken english though..

Billm2004

LOL no im from miami. lol

Billm2004

The mega was running times right there with me, even tho he was about 5 mph faster, my 60' was usually a full second faster than him.

jrussell

FWIW I tried going from 60psi to 35psi and all it did was improve traction a little. I figured the higher pressures would help after the launch, but it didn't seem to make a difference.
