2017-06-09 New Personal Best

**Updated** New personal best is 14.2 @ 100 6/9/17, rounded. See link: http://forums.tccoa.com/26-racing/14...ml#post1955945

Notes: 52* @ finish,~<3/4 tank,man. shift

I was hoping to do better, but I can take some positives from this. I beat my previous best by .36sec and 3.3mph. It did nearly as good as my 5.3L LS4 V-8 Grand Prix GXP when it had only a Cold Air Intake and a dyno tune. It would have beaten a few of the cars that had beaten me in the past like '05-'09 3V Mustangs, Z33 Nissan 350Zs, a Lightning, and a Supra.

So I'm happy that I got an old Ford modular 2V SOHC N/A 4.6L to keep up w/ a newer "LS" powered car. It just needs a much better stall than the '04 Marauder converter provides. It doesn't have enough grunt down low.

I come from a dusty place.

Well, I didn't have the results I had hoped for with ported nPI heads. The first set achieved the right flow numbers, but holes in the intake covered by epoxy were no bueno. So the same guy who ported those heads at this one shop, moved on to another shop and was tasked to port my next set. Needless to say, he was much more conservative and the car just didn't perform like I wanted. So not being able to get a hold of the rare "Renegade" heads, I settled for some Trick Flows. Also I had grown out of my Comp nPI "RV" cams and I had the shop order some custom grind Comp Cams...a good mix of the 102200 and the 102600 Xtreme Energy with a 113 LSA for good drivability. I got those two pieces in September 2011 and they finally got slapped on recently. Those mods + ET Streets are responsible for the difference between now and my previous bests. The tires actually slowed me down on my previous setup.

Have you got the slip you can post up on that pass and where it was run?

That 60 ft sucks if you have drag tires, and the eighth mile time and quarter ET and MPH don't seem logical.

Just saying.

Yeah sure whenever I get back to my desktop and find some free time I'll scan it up.

It is what it is. It hooked pretty good after mild burnouts at San Antonio Raceway. I have no idea why you would say real world results defy logic, but OK lol

1MTNCAT is a stickler for numbers. He's the only member here who lists his 60' times in his signature.

It's a 14 second run... I'm not going to nit pick your times. Hell, I ran my best time of 14.7 on the old engine years ago on street tires. I know it can be done.

Congrats on your new personal best.

I'm not particularly nitpicking times.

I'm saying ET and MPH numbers don't coincide. Its looking close to 5 MPH faster at the eighth and at the 1/4 than it should be at that ET.

Acceleration rates should coincide somewhat with MPH. Those are 13.5 - 13.7 ET MPH numbers on a car that had a 2.30+ 60ft and high 14.4 ET. The MPH generally in those cases are around 73-74 MPH in the 1/8 and 94-96 in the 1/4.

So I'm saying how is the acceleration rate and the MPH so much higher and quicker but the ET not showing it.

Now, What is the rest of the set up on the car? Maybe that will clarify a few things. Somethings different.

Thats all I'm getting at.

Don't forget higher hp will get you higher mph not always higher ET times if he can't get into that power band right away. Mmaybe he's running 3.08 gears?

Full list of mods? I read maurader TC, ported npi heads, custom grid comp cams, is that all?

I don't think with a 14.5 you will be beating any 3v mustangs or lightnings. But either way congrats on the new times!

I hope not! If he's running a Marauder TC and drag tires there is no way the 60 ft should look like that to begin with.

Not to dwell on this but
Just for an example cause it was the quickest thing to get to for data:

13.600 @ 099.46 Joel Bender - 96 TBird LX 4.6L/N2O 10/2003
13.717 @ 104.42 91BLOWNBIRD - 91 TBird SC MPX 10/2012
13.850 @ 096.50 95badbird - 95 T-Bird LX gutted, stock 351W N/A 2008
14.063 @ 097.84 John Speziale - T-Bird 3.8L SC 8/2012
14.076 @ 100.14 Wolfer - 94 t-bird LX 4.6L 2V/PI N/A 11/2012
14.245 @ 097.69 XR7 Phillip - 90 Cougar XR7 07/2012
14.500 @ 093.97 Mgino96tbird46 - 96 T-bird LX 4.6L 2V NPI on E85 01/2013
14.512 @ 096.03 Chris_Murder - 97 T-Bird 4.6L 4V N/A 11/2012
14.717 @ 092.45 Trunk Monkey - 95 T-Bird 4.6L 2V N/A 12/2007

So also take into consideration there are a couple SC's and a 4V motor on that list.

I'm not disputing the ET. Nor am I disputing the run. It is good. BUT, Its not pulling that hard up top to run that MPH is all I'm getting at.

TM what MPH were you running at 14.7? He's running street drag tires not Street tires.

Boys, I been doing this for a LONG time.

Looks like you'll really get cornfused when you see what the '97 Mustang did in the other lane haha

Like I said, the car doesn't have enough grunt down low and needs a better convertor.

Thanks, Trunk Monkey. It was my best 60' time too and this guy just wants to [email protected] all over that accomplishment.

3.73 FRPP. I've already killed 2 3Vs and a manual trans 350Z so that's moot. Haven't lined up with a stockish Lightning on the new setup yet however. I tend to tree people in my automatic cars.

With a MPH like that, you should definitely be doing better. Which converter are you using? That Mustang driver sucked big time. He should have stayed with you the whole time, his 60ft was atrocious.

Thanks for posting the slip and congrats on the new time. Like I said I wasn't disputing ET.

It should certainly be running much better than the 14.4 so you need to not worry so much about the MPH. Its making the power to be down in the mid- high 13's easily enough. More hook, Less slip, better ET and less MPH generally.

I see you have the TFS heads and aftermarket cams. That along with the wheel spin now things are starting to make a little more sense with the MPH. What is the engine combination & rest of the set up.

TM what MPH were you running at 14.7? He's running street drag tires not Street tires.

Boys, I been doing this for a LONG time.
Glad I got mentioned I'm shooting for better numbers this year fooling around with tire pressure, street slicks, weight loss, shift points, reaction etc. I'm hoping for at least 14.2 this year. Any tips for better RT? I'm considering a hand brake to help flash the converter before the launch my left foot doesn't react well with all the additional hardware inside of it. I keep practicing but by the time I feel I'm getting dialed in the car is so hot under the hood that I know I'm not getting the most out of it.

Leave sooner, like when you first see the 3rd yellow light.

If you add a hand brake, make sure it operates all four brakes. You could plumb a line lock to all 4 brakes, might need two of them. Just make sure you press the brake real hard when setting it.

That would react real nice, almost like a transbrake!

There's probably very little "nPI" any more. Maybe just the front cover, coils, water pump, computer, fuel pump, and A/C stuff. Finally had to upgrade from stock injectors.

Some other mods...
'02 Explorer block + PI intake + SCP headers and exhaust
Oh, and AccuFab 70mm TB, SCT MAF, '96-'98 Cobra intake tube + airbox

And once again, the tires hook. It just has nothing down low. It hurts the most off the line in 1st gear waiting for it to get into the rpm band ~3500+

That makes more sense. An aluminum PI motor with TFS Heads, PI Intake and aftermarket Cams so there is nothing NPI about it. Its a PI motor.
You should certainly be in the 2.0 or less 60 ft range with that set up. When you do the ET's will come down significantly.
Get some practice time on the track and work on the start through the 1/8. The rest of the ET will come on its own.
You have a much better engine set up than I do.

Check the tune below 3500 RPM. You may want to increase the timing and check where the a/f ratio is at.

Hmmm thanks for that input, gentlemen. I was thinking converter, but yeah doesn't hurt to look further at the tune down low at wot.

After my car being stuck at my buddy's for paint going on 3 years, I finally was able to get back to the track last night. I got a new personal best on my last pass, and it felt good to do that.

06/09/2017 @ 11:51:09 PM
'95 LX
Left:96
RT: 0.1344
60': 2.2658
330': 6.1298
1/8th: [email protected]
1000': 11.9332
1/4: [email protected]
Notes: 79* @ finish,~<1/4 tank,man. shift, 3682/3987 lbs



Edit: BTW, right before I took the car in for paint in August 2014, I took it to the track. The friend who painted the car had just finished making a fan shroud and custom cold air box for me. My goals were reached when I did a 14.3 @ 99 on my last pass of that night, and in hot summer weather. I wouldv'e been happy with high 14's, but the cold air setup proved its worth on that night. That was my actual previous best before last night.

This time around, I had my tuner adjust the torque converter lockup schedule and I was using Nitto NT555 Extremes. I didn't have bogging issues this time around, but slight spinning issues. The lockup in 2nd is very high and causes no issues any more, and 3rd lockup was raised. I can't help but feel that this motor would be better off not locking up at all in 3rd before the end of the 1/4.

Maybe it's the lockup that's killing the ET. The front half of those passes needs work. That 1/8 miles equates to a only a 14.46, but the 100 MPH top end charge makes up for it a little bit.

If you can apply the power earlier in the run, it has the potential to be mid 13's no problem. Converter, tires, skip locking the converter. I would start with not locking the converter.

Yeah, I talked to my tuner last week to see about raising the lockup point in 3rd gear like they did for 2nd. With these cams, lack of torque might be my problem. My race weight was 3987 so it needs more torque down low to get me moving. I wish I could have the best of both worlds...lots of torque and keep the top end. As it is, if I rap out 2nd gear, it locks up 3rd too quickly after the shift. It needs to let the cams do their thing to 6200 and then lock up.

With my previous RV cams and ported nPI heads, I was hitting high 14's so my current setup seems to have similar torque, but adds more top end to it. Having the NT555's vs the ET Streets on, and spinning a little seemed to help keep the motor from bogging like my last time out. This Circle-D TC was most likely built for the S/C setup that I'm eventually going with. I told my shop that I bought an S/C kit from a member here, and so they contacted Circle-D and they made one that will get me by until the S/C is installed, and THEN it will perform to specs.

I also look forward to finally getting to race the car with this setup in much cooler weather in the fall. Maybe that will be what finally gets me in the 13's.

Something I wanted to post this past weekend while I was offline...

So I talked to my tuner this week, and it just so happens he has another customer who is making a choice between a Trick Flow Track Heat intake and a P51? So whatever he doesn't go with will be available for sale for hopefully cheap. I'm looking at the Bullitt style intake to match with the TFS heads in hopes of improving the low end a bit without sacrificing top end.

I questioned my SCT MAF that Murillo MotorSports installed back when I took it there for a tune one day. I originally requested an '02 Mustang GT 80mm MAF and intake tube from the Fuel Injection Specialties, but back then they told me they wound up installing a '98 Cobra set up because they had it there available. When I wasn't happy with the performance at the track, I took it to Murillo who installed the SCT and tuned it. Track numbers improved back to what they were before the whole MAF/AccuFab 70mm TB/intake tube swap in an attempt to actually improve performance. I am just trying to explore if I just don't have the right combination of parts for good low-end performance.

I questioned the timing/degreeing of the cams, and the tuner said there are timing gears now available to adjust the location of the power band and we could try it. I remember back when I was choosing my cams, adjustable cam kits weren't yet available or just coming out.

I pretty much decided to get a 3800 stall convertor, since that seems to be a common component used by the faster 'Birds here over the years (on the track times lists). My current one is rated at 3200 but made more for the future S/C setup. I would like to get 3800 now and made for optimum N/A performance. I'm also going to have the tuner raise the TC lockup in 3rd to 6200 rpm (whatever mph that is) and see how that does at the track.

I was happy with the performance of my car and reached my goals of 14-second passes in hot south Texas weather, but after considering comments from members here and browsing through the track lists, I now believe that I should be in the 13's no matter the weather. I will make whatever adjustments necessary to reach those goals now. Of course, if I run this setup in the cooler Fall weather I'm pretty sure it will hit 13's, but I'd rather have the car in the 13's N/A year round.

Thanks TCCoA!

A higher converter to match the cams sounds good.

Ditch the converter lock-up altogether for the track, that only helps MPH, not ET. That partially explains why the MPH is inflated for the ET.
