I can tell you straight up, LS1's have more HP than me. Like I've said before, its the massive torque of TPI that is getting me that E.T. Anybody who's been around drag racing for any amount of time knows that you make up more time in the first 100' than anywhere else on the track. Today, with the poor launches i was getting(1.95-2.0), it was running 13.30's, which is right in line with the mods i have. The 13.15 was no fluke, it just shows what can be done with halfway decent traction.

NICE TIMES!!!!!!!!!!!!! i am shocked. with the mods done here on my car people expect me to run high 13's. I have a question - what rear end do you have 9 bolt, 10 bolt, ford 9" ??? Look at my mods I have below.... I just got done ripping out all emmisions and AC components. Now that everything is exposed I am throwing on my hedman headers this weekend. I will be boosting up fuel pressure when I find time to put in my 24# injectors. Also, i got a nice set of 1.6 rockers to be slapped in. Seems like alot of people are always stuck on the budget thing on this forum but i got the parts and lack the time to put them in...... well they will get done in the next month because track opens then. Reason why i am asking stating this is because of your low 13 run. I am leaning towards the fact that you run 3.73's. Get back to me on what rear end you have because i keep tearing through my USED rear ends and let me know how that gear is working for you.

Its the stock 10 bolt with all Moser guts, Auburn pro-series posi. TA performance rear cover. No expense spared anywhere on the car. I only buy top of the line stuff. As I just posted, the 3.73's seem a bit much now with the stock size tires.

You really shouldn't be boosting fuel pressure with 24 pounders. you don't even need 24#. mine are still stock. more fuel will NOT make it go faster!

For those questioning the weight of factory 3rd gens....

I weighed my "fully" optioned 1985 IROC-Z without the spare and before I installed the amp/subs and the car weighed 3600# exactly without me in it....... I weigh 250, makes for a very heavy car and 9.0:1 compression doesn't help either.

It might weigh less now since the power driving seat bit the dust and I replaced it with a non-power Flowfit unit. I've also replaced the vibrating driveshaft with a new factory aluminum unit. The 12" convertor has been replaced by a 2800 rpm 9.5" Edge racing convertor (w/lockup). But a Be Cool radiator and 700 gram (cough, cough) forged pistons vs 485 gram hypereutectic pistons have been installed. All of these changes have been installed since the last time I took it to the track 3 years ago.)

Called Spohn today to see if they could tell me why the car won't hook. I was told that I need the lower control arm relocation brackets. I kinda suspected this before, but i figured they would have told me when i spent $600 with them a few months ago. The guy I talked to was trying to convince me that the brackets are guarunteed to knock a full 10th of the 60'. Don't necessarilly know if they will, but in any case, I have to do something. Installing them on Sat. and going back to the track on Sunday. Sent all my info to edge to have them build me a custom torque converter, so hopefully 12's will be soon.

With those mods you should be there easily with your already posted times. I looking for 12's my next time out with a heck of a lot more mods than you have and basically the same car though I have the MAF. Hey Matt did you ever dyno your car? I would love to see the graph as to where you make your power and how much. Mine is posted in "Modded TPI Dyno Results." Allen

Haven't gotten it dynoed yet...i was supposed to go at the end of febuary to North Carolina and get it done, but i started a new job at the same time and its kinda hard to take 2 days off on your second day on the job I figure from 1500 to 4000 its got close to 400 ft/pounds. Hp falls off at 4750 because this is where it shifts in the 3/4 shift at the track. All the other shifts are right on 5k. The trans governor is smarter than I am.

Update

Installed 90/10 drag struts, removed front sway bar, and installed LCA relocation brackets. Car hooks VERY well on the street now. Small burnout and I can launch on it for all its got with no wheelspin . Planning on going to track tomorrow...weather permitting. Shooting for high 1.70 60's.

BTW there is no noticeable difference in ride quality/handling with no swaybar and 90/10's. It has a little body roll, but not as much as I anticipated. I don't drive like a moron either so that may help it.

I was bored the other day and I managed to post a vid of the 13.15. I figured some of you might be interested in seeing it.

Damn. This thread is making me wish I had a 305 TPI. A 305 TBI with stock heads, cam, and intake could never run in the 13's.

This seems like a post that drove a bunch of us 3rd genners into going POSTAL a few months back where a guy claimed he was was going to be the first guy in here to make his completly stock motor break a 12.99 with out removing any weight from his car, for some reason he never did get his car there but maybe Matt will???( maybe there related) who knows?.
I have owned several 3rd gens two of them GTA's both 350 cars weighing right at 3600 each.
And they bothe responded well to bolt ons just like you claim Matt but I never got any times below a 13.90 including open exhaust.
But I did bolt on a set of 64cc chamber aluminum edelbrock heads on one and the first time out with drag radials hit a 13.30 and tweaked it later on to a 13.10 @ 106.
To me it just seems like regardless of your launch you have 90 to 100 more lf lbs of torque than stock.

Theoretically on the TBI, you should be able to duplicate what Matt has done within reason. I would expect to be slower, but it has potential. A lot of guys are running 11's, and 12's with 350 TBI. They do the normal hot rod part bolt ons such as headers, 1.65 roller rockers, underdrive pulleys, ram air, stall convertor, etc. Also they swap to a newer computer for tweaking purposes. They also do some serious porting on the stock plenum or just replace it with a better intake altogether. There used to be a link somewhere on Third Gen that showed what a guy did to his stock heads that made some serious HP increases.... Look over on the TBI board for more ideas.....

Awesome e/t

Everyone who doubts it because they are comparing it to LS1 cars - 13.14 @ 110.4 here (2.2 60'). Basically, GTA matt would pull me really hard out of the hole, but I'd be pulling him in very hard and quick, which is why I have that 110mph trap. We'd cross the lines at the same time, but I'd go flying past him if we were on the street. He's getting the times because he has his car setup correctly to make use of the power he has, not because he's making more power than a LS1.

Just an observation Matt, but 'stock' gaskets have been known to be re-used, and 'stock' gaskets can be had at GM. In '90 I was running a 'stock' 1989 GTA that was trapping at 103-105... at least that's what I told people I'd be racing against...

That car only had 25K miles when it left my possesion in '92.

I'ts windows media player. If that link doesn't work, and I don't see why it wouldn't, you can go to www.streetfire.net , click on "videos" then click on "recent videos". my post should be on either the first or second page.


The reason I said the gaskets were original was because the runner gaskets were STUCK to the runners and the intake. It literally took a few hours with a bench grinder to get the gaskets off them. It was pretty obvious they had been on there a LONG time. I've had the intake off twice since then and have had no problem with the gaskets, I could have reused them if I wanted too.

Matt, I have all the same mods as you with the exception of this:

I have the stock prom, I have Control arms, panhard bar and sub frames (don't know if you have those. And mine in s 92 Formula, so probably lighter. I have SLP runners w/ ported plenum Otherwise seems to be the same.

My best time was end of last in in September, I was hoping to get a nice cool day but it was freakishly hot for a September 19th in Michigan 82 and humid.

Anyway, I was running pretty consistant 13.78-13.79-13.80-13.81 (you get the picture. All trapping at about 96-97mph with 60fts at about 1.80-1.82.

Only thing I have left to do is get it tuned on a Dyno sometime in April. I will be WISHING for a 13.10 but I don't even know if it'll do it.

I'll probably get to the track sometime by the end of Aprill so I'll let you know how I did if you'd like.

Along with the other mods in my sig I also have an Edelbrock panhard bar and Spohn LCA's. In the heat and humidity of summer I usually loose 2-3 tenths. The last time i went to the track, (two weeks ago and weather not looking good for this week either-rain) it was warm and a little humid and i was running high .20's and low.30's. I expect this summer it would run high .30's and low .40's. however the new converter should take .3 off---so maybe .10's in the heat???

The converter is going in in 2-3 weeks, but toward the end of April I have HUGE plans for it ....should be mid-high 11's.....all motor, hehe. I'll keep y'all filled in as parts arrive. It'll be pretty badass though.

Well, I guess it's very possable if I were to gain .3 from a custom tune and run on a 60 degree day then to run a 13.40, but I wouldn't expect better than that. Unless I'm underestimating the potential of the custom tune, I don't know.

With only bolt-ons, the factory tune is still pretty good. We haven't really drasticly changed anything so I can't really see picking up much more then a tenth with a good tune. I could be wrong. I've been meaning to pull the hypertech chip and make a pass to see how much it actually does. I would say my tune is pretty much dead on though. It could probably use a little tweak with the timing, but the fuel is dead on.

By the way...does anybody know if a 383 with a miniram, CNC'ed AFR 195's, and 226/226, .554/.554 would stand half a chance in emmision's? They don't visually check anything here- just a probe up the tailpipe and 2500 in park for 2 minutes.

Just a little taste of whats coming

Which puts me back at what I had originally thougth, A best of 13.5 on a 70 degree low humidity day. Don't get me wrong though, I am plenty happy with it. Hell, you should see the look on those LS1 guys face when I beat em on the street. It's priceless, the first thing outta there mouth is "how much nitrous" I just laugh. I'm sure lots of them would catch me if we raced long enough, but on the street it's a whole different ballgame.

Did I ever mention how I love to beat up on LS1's? them and those pesky little 4.6's. Actually, LS1's give me a pretty stiff fight from a roll, but I will straight rip them out of the hole

Had a guy at my work yesterday think that his 3000GT VR4 could beat me out of the hole just because he had AWD......CYAAAA

GTA matt, well, I finally went to the track Today and I ran a pretty consistant 13.5X. But now I seen to have a traction issue. I ran a best 60ft of 2.030 when I was previously running about 1.8's. So now I have to get that figured out and maybe i'll get better than 13.5.

All my times were very close but here was the best 1/4 mile run.

60ft 2.070
594ft 8.259
1/8 ET 8.750
1/8 MPH 84.65
1/4 ET 13.520
1/4 MPH 99.97

that's pretty good. A 1.8 60' would put you in the 13.20-13.30 range. Were you spinning or was it just launching softly? The LCA relocation brackets did miracles for me if you don't already have them.

Naw, I don't have the relocation brackets, I guess that will have to be my next move.

Yes, I must spinning pretty good. I wasn't tourqing it up either, just a dead punch from the line, and this was the most tire spin I ever had with the drag radials. It's funny, I seem to be gettting more traction on the street then at the track.

I was trapping at a little over 5100 RPM in third gear.

Now that u mention Hyperjunk chip, you might even want to try running the stock memcal and seeing how you do.

Stock, our cars tend to run fairly rich on the top end and are prone to knock.

Hyperjunk does nothing for the richness and adds in timing where almost anyone who actually does tuning removes it.

They dont do anything other than turn the cooling fans on at ridiculous temps and add timing at extreme(WOT) only and way too much. I have compared them hyperjunk to stock and found this and so have lots of others.

later

I have always gotten better traction on the street with my drag radials vs. the track..

You better change your signature, Street tires=Nitto NT555R's and i think you have more than just that *cough* pulleys *cough*i think some other things but im not 100% sure lol get your mustang out so we can see what she's got.

anyways on a coarse road my yoko avid s/t's hook pretty good from a roll. but im going to get some nitto's fairly soon, they seem like the best bet.

They are street tires lol. No pulleys. Just the SC and full exhaust. Stock clutch fan, stock tb, stock everything unfortunately. Stock MAF but I got that 75mm now to go with the 30lb injectors. Probably will not gain much from that though. But I hope with having full compression she will go a little better..haha. I think I'm going to go with some regular tires this time that match all the way around. I liked the hook with the Nitto's but it hooked so good with 3 people in the car last year 3rd gear took a hike.....

Around the 1000 ft. mark it shifts into 4th. I cross the line around 3500 in 4th. One run I acidentally left it in 3rd because i was doing my burnout in 2nd and only gave it 1 click up . it hit the rev limiter before the finish line, which is set at 5250.

At what 3rd gear RPM does it shift into 4th?

Also, with my new programming my limiter must be set higher than 5250 because I passed that in first gear yesterday. (by accident of course) But it hit the limiter at about 5700-5750

It shifts into 4th at 4700-4800. All the other gears it shifts right at 5k, but at the top of 3rd the TPI is really choking it down. I have the limiter set at 5250 because it doesn't make any power that high and I don't want to spin the motor too high if it happens to break a driveshaft or something.

Went to the test and tune at the track today. The car never really cooled down all the way, as I was hot lapping it, just trying to get some consistency down for later this summer when I am points racing. Ran a few 13.21's and .24's with 1.85 60's. I wasn't trying to launch on it as hard as possible, just being consistent.

The only thing I have done to the car since the last time it was run was a line lock, which makes for the most beautiful burnouts.

I've gone over the suspension setup somewhere in these 3 pages. here it is again.

Edelbrock panhard bar
Spohn adjustable torque arm/trans crossmember
spohn LCA's
Spohn LCA relocation brackets
Lakewood 90/10 front drag struts
front sway bar delete

If i put a stall converter in it, it would do some 1.70 60's

Matt you have to get that stall converter to hit the 12's consistantly. I would contact Precision Industries or Yank and get their advice. With the Spohn adjustable torque arm have you adjusted the angle of your differential? If so to what degree? -2? Thanks, Allen
