if it was a new roush you raced he should have trapped at least 100MPH as well which puts him about 5 MPH below where he should be which is right around where youre at.So it seems track conditions played a part as well.Dont worry just go to a different track (if youre lookin for a personal best time) or maybe even go on another day. Ive been to the track on days where weather didnt seem that bad but for some reason EVERY car was trapping at least 5MPH below where the shouldve been (LT1's-95MPH,LS1's-98-99, my mustang 104mph, C5's-100mph.) so it seems your car is running about right.If you wouldve went to the "faster" tracks with that 60' time youd be somewhere around 13.3ish,but then again, would that really mean your car is faster than it was before at the "slow" track??to some people thats debatable.

BTW-did you bother to check what other cars were trapping at? before you get down on your car for the low traps next time,see what others are running.The rason i stress trap speeds is cuz they are the best indicator of the power youre putting down.

 

I think your MPH is way too low, I have about the same mods, maybe a little more, but look at the MPH. My 60' sucks bad though, but you get the picture. I had very little tracktion in first and still a little spin in second.

 

Yes, 91 Octane is recommended. I get 93 when I put gas in my Z28.

 

Awsome thx for the responses guys!!

I think i will just go ahead and put in a LT4 KM, replace my PCM since it is reading wrong voltages and throwing codes, and fill her up with 93 and try it again.

Also i had some decent spin in first and 2nd gear would break loose for about 2feet. Not enough i had to feather 2nd though. Isnt your trap speed usually a lil higher if you have some spin?

A question for you M6 guys..I have to shift into 4 just before the finish line i dont really know how many feet before it, but it isnt very much. And 3rd gear will hit the rev limiter before the finish line so i have to shift into 4th. Is this normal? Thx guys!!!! Tyler

 

yes,i believe thats normal

 

For the time he ran, that MPH is about right. I was trapping 98-99 when my 60 ft was over 2.0 , and Im running an A-4.

Pntballty- How bad were you spinning out of the hole?
You list Nitto's in your sig but you were on street tires?
Get those Nitto's on next time. They make a world of diffrence.
Also, I didnt see anything about you having your puter programmed. Get it done, it will definitely help.

Someone mentioned the laptop to check your knock retard.
I use mine every time I go to the track and create log files.
Very beneficial to know whats going on with your motor.

Good example- I have a pretty good exhaust leak on my passenger side, and Im knocking pretty good even with the lt-4 km. I jumped all the way to 9!

 

HK45- I dont have Nitto's listed in my sig. I wasnt spinning too bad, 2nd gear breaks loose for about 2 feet or so.

Yeah im gonna get a new PCM since this one is going out. Im also gonna put in a LT4 KM while im at it, and some 93 octane gas this time. Hopefully this will solve my my probs. Any other suggestions? Thx! Tyler

 

I was shifting to 4th right at the same time as you when i had cold air and and cats w/catback. deffinatly normal

 

Sweet thx. Looks like im gonna need some gears pretty soon.

Do you guys have any other suggestions besides computer toon, LT4KM, and 93 octane gas? How much gas do you guys usuall run with? 1/2 tank? Thx! Tyler
