Drag Performance

[Ralph]

Can anyone suggest the best bang for the buck for improving drag ET's? Gears, chips, headers (long tubes), smaller tires? Any help will be appreciated! Thanks!

Chip or Tuner. THen gears and UD.

I went 14.25 w/ 4:10, Chip, UD, Denso and Thermostat.

What ET. do you consider satisfactory? Then maybe I can suggest lowest cost to your goal.

A high stall convertor from PI 3,000 will reduce ET by .5!

11"s :rock:

11"s :rock:
Roots blower 13 psi, Kooks headers exhaust kit, widened rims, drag radials= 11's

$10,000 should do it.

So ,
$12,000 = 13's and $11,000 =12 and so on .. :up:

At 11's you will need a roll bar, & if a Roots ported S/C, larger intercooler, MAF and a shot of nitrous. See Lidio's sig. He previously gave a ball park of $15K out the door.

Lidio hit 11's without nitrous, had no roll bar last time I saw him race. I was not being very specific (obviously) just ballpark.:D

[FiveO]

I thought Lidio's 11 sec run(s) was with a 50 shot of Nitrous.


Could be wrong....

Best bang for the buck.......I still say TRILOGY MOTORSPORTS SUPERCHARGER!

Don't waste your money on any thing else, except the widened rims and Nitto drag radials. This post was not meant to hurt anyones feelings, just to tell the TRUTH. :P

[sailsmen]

Roll Bar is a NHRA requirement for sub 12.0 and Lidio did report using Nitros on his best 11 run.

[sailsmen]

Per Lidio, "When I campaigned and drag raced Trilogy number one last year with only the stock Trilogy blower kit and nothing else done to the car, and I mean nuuuuthing…. it ran a very impressive 12.95 with 93 octane in 50-60 degree temps and 13.2’s to 13.4’s when it got to be about 85-90 degree temps. Then just before our trip to TX we then stepped up the boost to about 12psi and added 4.10’s, this got it into the mid 12’s with a best of 12.43."

Hey guys

This is about all she’s got in it I think for now. The conditions where very good this past Saturday morning, if not almost perfect. My MM ran its best…. 11.86 at just under 114mph. The sixty foot on only this run was 1.71 and the rest of the morning they hovered around 1.75 to 1.85s. The traction varied and I experiment with different launch tequntiques too. It ran several 11.90s – 12.00’s.

One thing I think I learned though was locking the converter in 3rd looks like it might have hurt my over all ET and MPH a little bit. My MM should have gone at least 114+ mph like it did a week ago at the track when the converter was not set up to lock-up at all.
But yesterday it did lock-up. I’ve learned in the past that if you lock it up at the right time in 3rd gear shortly after the 2-3 shift occurs, it can lower the ET and raise the MPH as well.
I’ve even locked it in the middle of 2nd gear on some race cars and left it locked through the rest of the run and shift right into 3rd with it still locked. But this was proven to be very abusive to the AOD’s and tended to some times really bog down the motors.

Any way I thought I had the lock-up hapening at the right time on the street while testing but it turned out to be locking to early and almost immediately after the 2-3 shift kind of bogging it down while at the track racing it. I wanted to raise the lock-up time or shut it off completely like I would usually do with my software when tweaking, but my laptop’s parallel port started crashing the system when I would try to burn a chip a day earlier so I used a secondary desktop PC that’s used with my Dyno to burn chips the night before. Basically I could do/tweak any thing at the track with my computer normally, but I was stuck with the couple of programs in my chip and that was it.

Although the 11.86 it ran is nothing to sneeze at, and it’s a personal best for me. I think with the conditions we had and the converter lock-up “off” or figured out I would have seen my predicted 11.78 but I’m not taking for granted how cool the 11.86 is and how good high 11’s in general really is for this much American iron going down the track.

I’ve said in other posts… this is about it for my personal MM. (I know, I know) I’m not raising the boost any more then the 13.7ish it’s at right now nor am I gona change any other real hard parts in the near future. Its ability to take the kids to school and truly drive it every day is uncompromised and I intend to leave it that way. The only thing that will make it pick up some will be the little shot of NOS on top of the boost when I figure out a better pump in the tank very soon.

Congrats Dave on your very low 12 second ET with your ride…. We need to hit Woodward Ave together this summer.

Thanks

This is Lidio's first 11 second pass in his Marauder, read carefully, no nitrous. I am aware of the requirements for roll bar and roll cages based on known ET's. All I am saying is Lidio told me he would not rollcage his car, it is a family car. I don't rule out he may; I am just not aware at the present he has either rollbar or cage.:)

[sailsmen]

Roll Bar and Roll Cage are 2 different requirements.

[Smokie]

Yup. under 12 roll bar, some tracks will permit large full frame cars such as ours to run high 11's without rollbars
Under 11, I believe you need rollcage no matter what you run. If I have it wrong please let me know.:cool:

[sailsmen]

Correct, http://nhra.com/tech_specs/ETQuickRef.html

The track I run at will let a high 11.0 late model car w/out a lot of mods ( Cobra or AMG55 ) run w/out a roll bar by itself on Test N' Tunes.
