What was your best ET before the mods and after?

Brett,

Are those the same numbers as your best last year? And are we talking running last night, when it was pretty warm and a fairly high humidity level?

If so, then you have actually picked up. Do you have slips from last year on a similar weather day you can compare to?

I'm not well versed in newer cars with EFI... but, with the changes you made, did it move your power band higher? As in, if you were shifting last year at say, 4000rpm, should you be now shifting at 5000rpm, because you're making more power higher in the rpm range?

Remember, you have a nice ride, and a fast street car. :rockon:

plus you added weight to her with the roll bar and subframes. I think those are some great times considering you have no internal mods at all the car weighs more than stock.. just my .02$

The weather and the track play a huge role. There are times I have to look back two years to compare numbers at the track in similar weather conditions.

I learned a long time ago to log every run including the weather data and of course any changes to the car. Otherwise it's like apples and oranges.

You can also use 'corrected ET' but to do that you have to know the weather stats and even then it will be different at different tracks.

My car slowed down 2 tenths when I put a roll bar in it.

I ran two 13.9s and two 14.00s. 60fts were 2.0, n I've been in the 1.8-1.9 range previous to these runz. My best with these mods was a 13.7 and with out'em I was runnin a best of 13.9s. I did add weight with the roll bar and sub-frames but also gutted my rear seat area and added the aluminum driveshaft to compensate and tryin break even. I'll just have to start loggin weather and tire pressures plus get some stickier tires and do more aggressive shifting to get the 60fts down.

running the same tires? are you spinning more? are these tires beat from when you ran them last? did it rain before you went again... i would imagine that would take some of the rubber off the track making it real green.

With all your mods you will be pretty close to the same ET but a couple tenths faster in the same weather. The driveshaft does abolutely nothing for ET but it is good to have. The rollbar will slow you down, but the intake should make that up and maybe some extra. If you really wanna see what the car will do, put good tires on it and leave the line hard. Leaving the line good will result in better ET then shifting like a mad man going down the track. PLus trying to rip the shifter outta the floor is how you break trannys.

...been rangin from about 99mph to 102mph both before and after the mods. The other night they were down a bit.

...the same Nitto 555R DR's I've been runnin for almost 3 years. No they haven't been really spinnin that much at all. My car sometime just launchin kinda spittin and spatterin then kinda like v-techin, haha! Rain it did too!

If it's a race only car I'd just swap in a c4 with a brake and a 4500+ stall. That setup has proven to take well over half a second off a very similar car going from a 4r70w with a 3800 stall. You'd probably lose a second easy.

im willing to bet it raining too.. i mean im not a big strip guy but i am into circle track racing and i know if it rains a few days before it washes the rubber off and the entire track loses grip. i could imagine its a pretty similar thing at a strip. how were your 0-60 times and 1/8 mile times compared to before?

Better tires and working on track time and you'll be fine.

what intake u running? i put a professional products and did not c any differnce but it beat the hell out of the plastic. like u 99mph to 102mph but spinning hard up throgh 3rd gear

Rodeheavers
07-25-2010, 09:49 PM
If you put nitrous and a supercharger on I bet those times will pick up! (just being silly)
New tired every year are a must when you are wanting to compare each years time slips, when tires get old and hard it will reak havok on your et.

tim u are right. drag raced down at orlando drag wa and the differance is night and day. w/traction and the way the car ran all around. buy the way got mine figered out thanks for the help c u on saturday

Its more so a pro street stick car that I like to race and run the crap out of, lol! Intake wise I have a-March ram air intake scoop to the stock airbox w/ a K&N filter, Rodeheavers custom upper intake tube, 70mm BBK Power Plus TB, and a C&L upper intake plenium.

Here's the big questions um stuck on at the moment, I bought somethingclever's Bullitt rims with 10 1/2's out back. They're pretty heavy I hear. Should I put Drag Radials on them or keep street tires on them and use them for show? Or should I use up my Nitto 555Rs on the stocker's an put the biggest DR's on them I can and swap them out everytime?

Um lookin into buyin the new M/T drag radial II's or the new Nitto NTO5R's, anybody runnin either?

Believe me Tim I would luv some Nos er some sort of power adder for sure!

If you want a real tire go full slick and just run them at the track...then get street tires for your street wheels. DR's are a pretty big handicap unless your suspension is setup for them...

AdamantiumSilvr
07-26-2010, 12:56 AM
...I'll do the drag radials on the Bullitts so I'm ready to run at all times and then do the full on slicks on the stockers down the road to race strickly at the track.
I'm also lookin for a nice full set of lug nuts for all four corners of the Stang? Lemme know if anybody got any, preferably black ones?!

if you're going to paint the lugnuts black why not just use your stockers but paint them black?

AdamantiumSilvr
07-26-2010, 02:07 AM
...about paintin the stock lugnut's, but as much I take them off and on they'll just get all nickt up. Plus one of them's a lock lug that uses a special socket. Um really not a fan of the chrome ones, I may settle for them thou. But if they make a black set or if I could find black ones that'd be tight!

Brent,

Were you able to compare these runs to comparable weather from last year? It's possible you might not have run in weather that warm/humid. Thursday was pretty toasty. A log book is great, but at the very least, write notes on the back of your timeslip for weather (doesn't have to be exact, just what it feels like to you), tire pressure, launch rpm, shift rpm, did it spin, and other things in the set up prior to and during the run.

Slicks will always give you the most complete contact patch, but remember you can't run them in Trophy, or any class that will call for a DOT tire.

MBH

little late to chime in, but maybe the clutch is slipping a little? Maybe I missed it, but are you still on stock clutch? If you're runnin it hard and have a bunch of miles on it, maybe it's slipping on you a little bit?

driller
07-26-2010, 10:18 PM
A DOT drag tire such as the Hoosier Quick Time Pro will be uber light and perform almost as good as a slick while still being 'street class' DOT legal at the track. I had PRP techs question me about a driveshaft loop once though when they spotted the 'bald' Hoosiers thinking they were a slick. LOL

AdamantiumSilvr
07-27-2010, 12:45 AM
From here on out um gonna be at least throwin some more notes on my time slips Chuck for sure.
As for the clutch Bo it is the stock one, the Stang just turned over 50,000 this year. It could be a little, I have heard u will know for sure if its slipping. It hasn't been feelin any different than it has in the past.
Um still gonna be doin some research on tires over the next while Driller, those Dot Hoosier QT's are ones I'd go with instead of the full fledged slick thou um thinkin.

ChuckT
07-27-2010, 11:42 AM
My 2 cents, if you don't have the driveshaft loop, get one, regardless of slicks or DOTs. If you hit the strip even just a couple times a year, it's cheap insurance against pole vaulting and the damage that could follow.

Brent, have you tried raising your shift point rpm? If not, you could always test that and see if that helps (take notes! :D ) your ET.

07-27-2010, 10:43 PM
the hoosier q-times are real good rubber. ran them for a year every week no probs would recomend but i have not ran them 4 about 12/14yrs but they was good then and would try them again!!

I picked up a Lakewood universal Driveshaft loop off of SCS and had it installed last time at the shop. I should mess with the shiftpoints but I need an overview from someone who knows how to work the Predator Diablo tuner. Still up in the air with tires thou.

AdamantiumSilvr
08-15-2010, 01:48 AM
I forgot to mention that when I pulled the Stang out and left to go to this day at the track. The first mile er so down the road the car kept spittin n spatterin and I was thinkin of not goin but went anyway cause it just started to run normal again. I'd press the gas and it would hesitate and not really go. I thought it was cause I pulled it out a couple days before and just pulled it right back in the garage, cause of rain.
Sooo I got it out the other night to go to the Pitt Mills cruise/show and it did the same exact hesitating not goin anywhere when I'd press the gas. What would be the cause of this?

i would say to clean the MAF first, i know the plugs are new, but how about the fuel filter? I cant remember if we ever changed it...

AdamantiumSilvr
08-15-2010, 03:59 PM
Tim just put brand new spark plugs in it last time it was at the shop. No, never messed with fuel filter thou. And as for the MAF, I've seen after market ones but never seen or messed with the stock ones.

Thanx for the suggestions on what yunz think might be up. I dunno it's never really acted up like this before. Although I did neglect to mention I ran like 3 gallons of that Street Blaze 100 octane unleaded race gas in it the last two months er so. Could of messed with it a bit. Hit me up with your #er again John, my phone took a crap on itself n I lost everything so I got a new one.
