Another "New time slip" post

So how did she do?

R/T -- 0.9874
60' -- 2.2622
1/8 -- 9.0596
1/8 -- 80.67 mph
1/4 -- 13.8770
1/4 -- 102.25 mph

I was pretty pleased with it, especially since I was running against an '01 automatic LS1 who ran 13.6728 @ 102.88 mph.

My previous best (before 1LE elbow, Y pipe, and LT4 KM) was 14.248 @ 99.94 mph

Any comments/suggetions for me?

Obviously, I can work on my reaction time (best all night was 0.75), but is a 2.26 60' time reasonable?

How much et improvement can I expect just from getting a better launch?

Your times look pretty good for your mods. Your 60' isn't bad with street tires. Generally with every .1 off your 60' time, you take off .15 to .2 off your overall 1/4 mile time. But this isn't always the case.

I think you did REALLY well! excellent times for the mods. Get the suspension down (upgraded), and add some slicks maybe a stall (dont remember if you are a stick or not) and you will do alot better. Just think, cut .3 off the 60 and lose at leat .5 off the overall time! Pretty damn good if you ask me-good runnin' car you have!

1.7 is lowest 60 I have seen m6 cars do in my area, but that is on drag radials, on street tires 1.9s. Good numbers over all, practice your launch some.

I wouldn't say that 2.2 60's on street tires is GOOD

I have been cutting consistant 2.0 60's on street tires every since i had the car to the track when i first got it, to the present time. I can occasionally pull a 1.9 60', but then i run into the OBD1/high stall problem.

Let me add: "an M-6 where you actually have to know how to drive"

LOL! Thanks guys, I'd like to think I know how to drive

The car does run great, it always has. So in order to get the 60' times lower, the suspension and or tires is where I should look?

After the last trip to the track, I pretty much decided to leave the motor alone for now, and concentrate on the suspension. I ordered a 1LE PHR (mine is twisted) and the SLP sub frame connectors.

I wasn't thinking these components would help me in the 1/4, I was mainly going for handling improvements; but if they help my 1/4 mile times, that's ok too

buy a set of lca's and bfg drag radials and then you should be able to cut 1.9-1.8's, that will knock off .4-.5 off your e.t. and you will trap a higher speed.

those are decent times!

i think thats what a car with your mods should run...

2.2 is decent with street tires... my best has been a 2.1 chirping off the line (not WOT obviously) i thik it has 1.9s at most with stock vert and DRs...

if u can get ur 60 into 2.0 or even 1.9, ure a mid 13 sec lt1 with min mods
