last time i went to the track, i ran a 12.6 @ 118mph. only thing that has changed since then is now i am non-seq and i added a diff brace. I ran the same shitty 2.3 60' as i did before, only now i ran constant 13.3's @ 111. where as before i was running constant 12 sec passes.

i actually ran into cam from pettit out there, he said that runnin non-seq should not effect my mph and how the car drags.....any ideas?

 

I donut have any ideas but im almost 100% positive it shouldn't effect your times.... Is it full non-seq, poor man, etc?

 

maybe it was just a bad day...

 

not sure, i think the poor mans way, i didnt do it myself. wither way i hate it and will be going bak to seq soon i hope.

 

actually it was perfect, only like 65* not very humid, unlike before when i was there is was like 85* and like 100% humidity

 

What's your boost pattern look like? I know you're non-seq, but is it a rock-steady boost once it hits until redline?

 

it spikes like 15 then holds 13.5~ and does hold solid till redline

 

Did you tune it after converting to NS?

 

i dont think they adjusted the tune.

 

Have you got a datalog of the run?

 

Personally, if I changed oil brands I'd get it tuned again out of pure fear.

 

change your plugs.. use different fuel and try it again..
although if she werent tuned for nonseq...

 

Non-seq should mean nothing in terms of the tune, at least above 4500rpm.

 

I would think non-seq would make a difference. You won't be at full boost until a higher rpm, so I would think it would affect your 60' time quite a bit. Which is why your trap speed didn't really change, but I bet your 60' did.

 

He states that his 60 foot remained the same, but his trap speed dropped by 7 mph, which is a very significant amount......

 

You should be physically able to feel the difference of -7 mph. trap if you were used to the top end power. Sounds like a hiccup somewhere in the new set-up. Slight exhaust/Boost leak? I double check all of your block plates and nipple/ caps. G

 

Wow, I really misread that one. Sorry.

 

Or maybe you just suck at driving.

 

Come to realize that 118 seems strong for 324 rwhp. Your current trap speed is a bit more on line. 111 to 114..

 

thats whats i was thinkin.../\

 

I've heard that you can't use sequential maps on a non-sequential setup:

Well I just had my car tuned by steve kan a couple weeks ago and he said if I go Non-sequential I wont need to change my tune at all. So maybe its the way he tuned it but I think it just doesnt matter wether you sequential or non.

 

Real nice antonio.

You most certainly should not run a seq map on a non-seq map, and vice versa. Why? because you're seeing different boost at different rpms throughout the rev range. Seems pretty obvious to me......

 

He most likely tweaked the fuel values for the applicable pressure and rpm cells you'd see if you ever went to non-seq. Regardless, if it's my car, I'd still check AFRs after a change like that.

 

Yup, now that i think about it, it makes sense... Your probably not hitting full boost until 3,500 maybe even higher, whereas on the stock twins you were hitting full boost earlier.
