well, i went to milan last night and there were only like 20 <A TITLE="Click for more information about cars" STYLE="background-color: #f0f000; " HREF="http://odysseusmarketing.com/walt/go.php?nid=23">cars</A> if that racing, i got about 20+ runs in. but i wasn't really happy w/ them except for a few... now i do have the 20' chrome reps w/ 295/40/20 Kumho tires.

i think my main problem was 60ft times. my reaction time was probably the best out of anyone even though it doesn't matter. MPH basically was staying the same throughout the night 97-99mph.

and the thing was, was i was eating people up out of the hole, but once i hit 3rd is when they took me over.

my best run was:

Reaction - .557
60 FT - 2.128
330 FT - 5.853
1/8 ET - 8.904
1/8 MPH - 80.48
1/4 ET - 13.835
1/4 MPH - 99.53

that was probably my best 60 ft time too, i was disappointed, do you think if i swapped out my back wheels with my stock 18's w/ the F1's on them could i get a better 60ft time? im pretty much still stock.

out of 20+ runs i only got in the 13's 5 times, 4 13.9 and 1 13.8, i was mostly 14.0-14.3 all day, avg 2.2-2.4 60ft times all day.

my best 60ft was 2.089 and ran 13.92..... as long as i was 2.15 or better i hit 13's, i want to be under 2.0 so i can get mid 13's.

 

Well, I'm going to be honest with you, so don't take this personally. You have basically 0 performance enhancing modifications done to your vehicle, you have lowered it and you are running larger then stock wheels and tires, which I'm going to assume bumps up your overall gear ratio. This hurts the vehicle's ability to transfer weight, as well as your overall acceleration. I'd say if you went back to your stock wheels/tires and put it back at the stock ride height (and I may get flamed for this) your 60' times will probably drop to 1.9 provided you practice your launch. This will put you around 13.4 which is pretty reasonable for an 01+ model, not knowing what the weather or altitude is where you are at. I'd say your truck is performing about like it should. Good luck!

 

What he said.

You've done nothing to improve performance and everything to hurt it:

1) big wheels switch to stock or slicks
2) lowered, not much you can do, if QA1's adjust them
3) cat-back can hurt a stock truck

I think given your mods, a 13.8 is pretty darn good.

the 20's are probably hurting you, turning your 373's into 355(or less) gear ratio, plus they are heavier( I don't know if that makes a huge difference though). do you have a boost bypass hooked up? you probably have 2-3 tenths more hiding in your 60 ft times, your MPH should be higher though if you swap your gears or put your stock tires on a the track. not bad times though considering your 60ft. the guys pullling on you in 3rd gear I believe is from your 20's.

 

Because you lowered the rear 3" and the front only 1" I would think that you actually helped yourself there with built in weight transfer. You certainly helped your pinion angle with the 3" rear drop.

What seems to be hurting is the 20"ers. With stock wheels and tires a better 60' is easy with stickies it'll be much easier.

What was the weather like? Temp? Humidity?
How many miles do you have on your truck?
How much air pressure were you running in the rear tires?

My first trip out I ran 14.0. I didn't have very many miles on the truck and the weather was hot and humid. Not much at all has changed on my truck since this run...just the mods in my sig. So keep at it and get some wheels to race with...stock or stickies but get the 20"s off for racing.

 

well, it was about 55 degrees or so, not humid, it got down to around 45 degrees later, and thats when i was consistant 13.9-14.0's. another problem was that i was "Against" a 20mph wind.

do you think there will be any difference w/ just swapping out the rear to stockers, or should i do all 4??

and i have a few mods that better my performance, yes the 20's down my gear ratio, but the K&N air box mod is good for about 1PSI in boost, and the shift kit is firmer shifts, and the bassani is suppose to help performance on our trucks, and yes i do have a boost bypass.

 

Bassani will not help your performance............I would not be upset at all with those times.

Why don't you swap all 4 tires and run on the 26th. We had bone stock guys (not even a K&N panel filter) running 13.4's last spring at Milan.

Your times/speeds vs mods sound just about dead on to me.

How was milan hooking compared to last year?

Don't feel bad Snake, I'm in the same boat as you here in Phoenix. Lowered on 20" Kumhos with lousy 2.2-2.4 60' times. I've run a best of 13.6 at 105 in the blue truck. My white one was 13.5 at 106. I've only got about 1200 miles on the new one though. This is with a chip, filter and 4lb pulley. My almost 2000' elavation, lousy weather, poor track prep and terrible driving add up. Spinning half way down the track on the 2-3 shift doesn't help either. Slicks and traction bars are my next mods. I figure with my trap speeds I could be low 13's / high 12's with the right 60' times.

well to me it still feels like a Skating Rink.... i took the cobra last year, but i pretty much still spun alot both times....

when i was heating them up, i held the brake, put the pedal not even half way down and got it to rev half way, released the brake, still hold gas not even halfway down, and it didn't hook up until i got to the lights... it's still slippery as hell.

but they did repave the end of the track where you slow down, that's nice and smooth now. it was a little bumpy before.

yeah, im gonna try it w/ just the rear stockers on next week maybe, and see what difference that makes, then i'll either get nitto D/R or something for the stockers to put on, and then i'll get a chip and pully.

what size tire is good to run with the stock 18 rim??

 

Like others have said, you basically haven't done any performance upgrades. No offense, but exhast isn't going to do anything for us. No one has found proven gains... The 20's are going to kill you, and if you are going to swap out the rears, might as well swap out the fronts too.

-Mike

 

yeah, i know i should swap both out, but it would only take longer to do, just the back would only take me 10 minutes... so im thinking i want to see what a difference just the back makes, and if im not satisfied enough, than i'll swap the fronts too.

im not terribly upset w/ my times, just thought i would do a little better, i knew that i was gonna have a tough time with gear ratio and traction because of the 20's...

13.8 and a few 13.9's are pretty good, but there were plenty of times that i was 14.6-14.8, i was talking it over w/ my friend and i was telling him, "man im not use to being the slowest" and he said something very true, he said "dude, it's a truck, you lost to camaros and old 5.0 hatchbacks w/ slicks....." how many other trucks you know that run that good?

i did face a diesal chevy w/ propane he ran 14.9 and i ran 14.1..

 

I would love if some more MI guys would realize the great tracks on the west side of the state. I gladly took the extra 1.5 hour drive for faster times and funner/cleaner tracks.

It is difficult to dial in or figure out your truck when you run SOOO inconsistantly due to slipping and sliding.

--Joe

 

Remember that you did make 20 or so runs, and you probably didn't have adequate cooling time.... These engines love to be run very cold.

 

yeah, true that Joe, the left lane at milan is so terrible even w/ the repaving, i took off great in the right lane, i had 1 or 2 2.4 60ft times, other than that i was consistant with the 2.2/2.3, but the left lane was so bad i almost killed myself and i saw a camaro almost kill himself too, i took off sliding a bit, then hooked up, and all of a sudden it shifted to 2nd and i was almost completely sideways, i was only about 5-8ft from the wall, i had to let way up to get it back under control and i was racing a probe, and he got way up on me, finally i got her straghtened out and punched it, almost came back to win, i ran a 16.6 and he 16.4.... and i came back to the left lane, and you could see my tracks of almost wiping out, so i found the secret, in the left you gotta get as far on the inside (towards middle) as possible, the outside is real slippery for some reason..
