I finally took the car to the track at Temple Academy Dragway on Sat. It was a test & tune night, and I found out thats not the time to be at this track. It was nice that you could get in as many runs as you wanted, but I found out they don't prep the track on these nights, so traction seemed equal to wet pavement. I ran 8 times with pretty much the same results. 12.9's @107-108mph, spinning all the way through first gear. I'm running 245/50/16 Nitto drag radials. I've only raced once before in a Mustang ~5 yrs ago, so I'm a novice, but I've spent the last year modifying, burning chips and testing with a G-tech, so I've practiced launching. As you can see from the reaction times, I was really concentrating on how I launched. I tried off idle to 2000rpm launches with the same result. At this track everyone has to drive through the waterbox, so I think water gets spread all the way to the line. After talking with some regular racers there, they said their 60fts. were off ~.2, and blamed it on all the import guys dragging water to the line. Anyhow, I had fun. I feel like I can run much faster with traction, and knowing I'm still far from optimized on the tune. It's amazing how far I could leave these ricers that kept lining up with me. Most all of the newer Mustangs were running 14-15's. There was a brand new Subaru WRX running consistent 13.7's...watch out for those guys on the street. Here's a couple of slips showing best time and best mph. Any comments from you experienced racers are appreciated.

Oh yeah, that 2.2x 60ft time is holding you back. If you can cut that down to a 1.9x you'll EASILY pick up .4 -.5 That's mid 12s baby! Hopefully that's where I'll be in the next month or so.

those are very good times for that track, i usually run 2-3/10th's slower at that track then i do at RCR.

With the nitto's you have to do at least a 5 second burnout and feather the go pedal to get any decent times. The best I could turn with them was 1.84, but I also turned a 1.84 60 ft on street tires, so really I picked up nothing.

Practice makes perfect.

I have a "similar" drivetrain combo (same gears and stall) and Im getting 2.0-2.05 60ft times on a semi stock l98 and radials . Im only running mid 14s too so you should easily be able to beat that with nittos and much more power. Good times in the 1/4 though!! Good to see a car work w/ 3:73s. I think mine are too much and maybe Ill go down to a 3:45. Dont know yet.

Great MPH! Just figure for every tenth you shave off of your 60 foot - you stand to knock about .15 off your overall ET. The MPH indicates you have a mid 12 second car easily w/ more hook. Congrats.

Steve10

I did good 3-5 sec burnouts. My tires were so sticky, by the time I picked up my slip and parked, they were absolutely covered with rocks.

87 B4Z, I've heard RCR hooks really well. How far is it from Austin? I live 50 miles E. of Austin, so TAD is only 45 miles for me.

I wish I had a 3200 stall and a little more gear. This cam and intake combo love to rev. I'm shifting at 6500rpm, and it's still pulling strong, but I'm afraid to push it.

87 B4Z

i live just north of austin and it takes me about 1 1/2 hours to get there

Sounds great man, nice work. Just sounds like you need to practice at that track, thats all. I have a setup similar to yours and now i am all excited! Keep up the good work and continue to inform us on your progress. Oh yeah, i wanted to ask, what type of cold air intake are you using, or how did you go about making it? I am debating on the intake still, i do not know what to use. I am thinking of just using the stock air box and doing that ram air mod. Take it easy-Bryan

Steve10

Check it out below. I ordered 3" stainless weld 90's and found some 3" stainless here at work, tig welded and connected MAF with red turbo hose, 4"x3" rubber sewer connector at TB. Routes to a 9" K&N conical through a hole I cut in the sheet metal. Hangs just under the front fascia. With a camaro, I think you guys have a decent setup already.

MdFormula350

great times!

86IROCNJ

Wow, thanks for the quick response, with a picture none the less! Thanks, it looks good. More ideas for me to ponder.

DannyT

Some of you will think I'm crazy but I'm actually considering putting my original 2.77s back in place of the 3.45s I've been running. I refuse to run slicks or drag radials at the track because I don't use them on the street and I'm not interested in how fast my car runs in a condition different than the one I drive it in.

That's the same reason I leave my tires at 35-40psi and don't strip the car down in weight.

Think about it, as long as I can break the tires loose all the way through 1st gear and most of 2nd then a shorter gear is useless. With a taller gear I can get to WOT quicker and can shift later. And I don't need to remind anyone that's raced on the freeway that the taller geared cars are MUCH faster, at least matched with the 700R4.

i have some 2.73's and a 2 series carrier you can upgrade to :rockon:

John Millican

iTrader: (1)

Steve, do you have times before the intake and cam upgrade?

DannyT

I still have the original 2.77s with the 2 series carrier sitting in my garage

Danny, Why?

Your problem then is traction, not to much gear. When you put in a ring and pinion you expect to have traction problems. Why put in a longer gear and loose performance? I'm confused....

Free Bird

So use DR's on the street.........:lala:

Steve10,
Very nice times. I hope to be in the same class as you some day. I also have the ZZ4, but I pu t a CC306 cam, and will be going w/ the HSR. I'm hopin to hit some good #'s

DannyT

I know the problem is traction but there simply isn't a whole lot we can do about that and still maintain excellent handling. I know there are some suspension parts available that will help with both but I'm not sure what I want to do. I haven't decided completely to switch back. I'm going to wait until my car is running again and then take it to the track. I was hitting redline just before the 1/4 mile. My power band will go up (adding Super ram plenum and runners) so we'll see what speed I cross at. Hopefully I can wind out 3rd until 115MPH or so.

As far as using DRs on the sreet.....well I would rather give up a little off the line traction than replace my 275/35-18s that I have on there. They do wonders for handling.

Great time slips. Those 60 footers are killing you. Have you tried patting/feathering the GO pedal through 1st gear yet?
Like John asked :
Do you have any numbers from before you swapped the intake?

'87FAKE-IROC-Z

Hey Steve10 and 87 B4Z,
I race at RCR too. we should all go out there one night! would be fun.

unknown_host

iTrader: (1)

but my 2.73's will take off that extra .04, you cant turn that down....

DannyT

Hmmm, you make a tempting offer.

Steve10

Millican, I only swapped the intake and 3.27 to 3.73 gears, I was already running the LT4 Hot cam with my Accel LTR setup. This was my first time to ever take the car to the track, so I don't have track results before. I have been chip burning and testing with a G-tech on the same stretch, then logging the results for a long time. Right before I went to the track I ran 12.86@112.5 on the G-tech, so I believe like most have always said, 4-5mph off and very accurate on the time. With that said, I looked back in my log, to the best LTR run, which was 13.32@108.2.

I feel like I've still left some on the table with the tuning. I recently bought a wide band setup and started going back through the tuning process. I've been wanting to ditch the MAF and go with the MAP 730 ecm. If I do that, you guys think I can hit 110mph? That wouldn't be too bad for Vette heads, would it?

I've been talking with Steve Spohn this week about my 60ft's and setup, and he thinks my stiff Koni shocks and the 2500 stall are killing me. I'm really considering a 3200rpm Vigilante.

89Formula350WS6

What I'd give to cut my 60 footers down from 2.10's to 1.8-1.9's.
My last mods gained me over 3 tenths in the 1/4 but NOTHING in the first 60'.

try some lower control arm relocation brackets.

89Formula350WS6

Thanks Derfrank. I'll make that my next mod after the 1.6 RA's that I just got & I'll report the changes in my sig whenever I can. I have owned this car about 5 years and never changed it from stock til a few months ago. I can't believe how much it has improved for so little work/$$. It's also great to see that the same results could be had with any 350 TPI and I didn't just happen to get a ringer like a few people tried to tell me.

89Formula350WS6

Forgot to ask ::
Bolt in or Weld on ???

Der91Z

iTrader: (1)

I would get weld in because of strength.

89Formula350WS6

Thanks again for the advice.
