I want to know everyones 1/4 mile times and what mods you have on your TBI cars.... who has the fastest TBI on this board?? (this could get interesting! )

PS- good ETs or bad ETs--->tell even if it is a bad..

 

ok, mines kinda confusing:have 2 main tracks here:ennis(1/4), and denton(crappy 1/8). when i was bone stock i ran a 10.9@63 in the 1/8at ennis and a 16.835@80 in the 1/4. stock i ran a 11.67 at denton. so there is about a second difference between how good the tracks are. now, i am running a 10.3 at denton, so im thinking a 9.4 or so in 1/8 at ennis, and maybe a 15.7 in the 1/4

 

this is with 3" pipes catback, dump, crossflow(but dumped so is kinda pointless), K&N, ghetto ram air, new fuel filter, 160 stat. just put on a B&M shift kit, manual fan switch, coil, cap, rotor, and real ram air, so we'll see if it changes any next time i go to the track..oh, this is a 305 TBI ,700-R4 with 2.73s

 

come on all give up your times!!!

 

14.209 @ 95.46mph
that was with posi w/3.54 gears(dana44 rear), spohn rear suspension(all rod ends), 2000 stal convertor and shift kit, edelbrock performer heads(60cc chamber, 2.02/1.60 valves), 1.6 rockers, edelbrock performer tbi intake, edelbrock headers(1 5/8 primaries/3inch collectors), !CAT, 3inch cat back, ultimate tbi, 350 injectors, adjustable regulator, stock cam, and stock chip.
i have since added a LT1 cam, switched to a holley tbi intake, holley 670cfm tb, a shortened exhaust system, battery to be relocated, and i will have a spool and 4.09's in the rear before igo back to the track. the car has also lost a lot fo weight, previous weight was 3280 with me and gas in it, should be closer to 3100 now. jprevost is also gonan be doing a chip for me as soon as i can get some data logging done.expecting to be around 300hp at the wheels adn run in the low 12.9's or 12.8's at around 105mph. we will find out about that on march 2nd when e-town opens

later

NJ Speedster, that is serious power coming off the old lo3..
that is wicked that you just didn't swap to a 350 like a lot of people do to race with---->keep up the good work on that lo3 :hail:
its good to hear of that little engine doing so well at the track..

PS-good luck on the strip

 

in the sig :lala: :rockon:

 

also in sig, but I have a 350 with vortec heads and a crappy cam
doesn't really count except that I'm using the GM ecm and TBI.

 

90 RS convertible here. Spent the day at the track Saturday: 60' 2.394, 1/8 mi 9.880 @72.18, 1/4 mi 15.276 @ 91.12. Mod's in my Readers Ride Page which still shows my prior best time at the same track last October (California Speedway in Fontana, CA). Lon
https://www.thirdgen.org/rides/index...ew&rideid=5460

 

16.4@84mph K&N filter open element, Catco cat, MSD 6A, I posibbly have TPI heads but not sure. Auto tranny everything else stock.

 

I went 15.05 at 91 mph. THat was with headers 3 inch exhaust, edelbrock intake and pulleys.

 

13.18 at 102.52 MPH when i had my stock cammed and stock head LO3

 

What's your gas mileage like? Decent enough for an everyday driver? I want to run low 13s or even high 12s but still have a good everyday car to drive around.

 

I don't know what Tim's milage was like but let me point out that he would drive his RS on the streets with uncorked Borla cat-back and slicks w/ skinnies. The guy had only one seat, for him! and the rest of the car setup for the strip, not as a daily driver.
The car was running really rich because he had the fuel pressure reg turned up so he didn't loose any horsepower beyond 3000rpm! So I'm guessing when I say city was like 10 and highway was probably around 15.

 

16.1 at 86mph.At the time I had headers,flowmaster exhaust,b&m shift kit and under drive pulleys.I should have new times in about a month.

16.182 @83.8 with mods in sig.

I can make some excuses for not bein in the 15's, but I'll get there soon enough

:lala:

 

OUCH!
What are you getting with that 350TBI cause that's another of my opitions.
As for 1/4 mile ETs, I've never had mine on a 1/4 mile but I can keep a carlength on a Mustang that is running 14.5s somehow.
My RS is quicker than any other RS I've ever driven or rode in. I guess whoever had it before me did some stuff to it. My intake manifold doesn't really look stock, it doesn't have the firing order on it like the other ones I've seen......

 

1991 Formula 5-Speed TBI 49,000 miles
14.89

Dual snorkel H.O. air cleaner w/K&N
Hypertech chip
Hypertech Pullies
Holley ignition module
MSD coil, cap, rotor and wires
AC rapidfires
Larger y-pipe
Cat Co cat
Dynomax cat-back
Firestone Firehawk SZ50ep tires

That time was with the stock 3.08 open diff rear
(Couldn't hook at all)

Was planning on putting in 3.42's with limited slip which should have put me around a 14.5 or so.

 

city mileage was bad because i am way too easily encouraged to show off, even if thge chick is ugly(hey, she may have a cute friend). my highway mileage was around 23 with the stock cam and that was with a dead torque convertor lockup, could have been aroudn 25 or 26 prolly if that had worked.
dunno wht the mileage is with the new set up yet. i'll know more about that soon though.
and jon, both front seats are back in wanna go for a ride?

When I ran her stock, she went a best of 16.8. I could never run her will all my mods in though...track closed :P

 

hey tim i thought i had 1st dibs on a ride ...anyway to answer your questions 15.6 @ 89mph w/a 2.18 60' and i was still having some tunning issues w/the fuel pressure at the time....mods were...hedman headers 1 5/8 primaries, 3" flowmaster cat-back, ultimate TBI mods, 160 stat, hypertech chip, AFPR, torsen posi w/3.73's and removed rear seats....bought tim's old performer manifold which should be on this weekend...also eliminating the cat, and tim practiced his welding skills by boxing a set of LCA which will be put on w/spohn relocation brackets...with that and a set of drag radials im hoping to jump into the high 14's...who knows

 

Oops, dont have times in sig But yeah, best time is 17.118@79. That was in BIG heat and before I added my thermostat and cooling fan switch. Gimme cool weather and i'l lbreak into the 16s guaranteed....

About the best my Formula has run so far is 17.2@78mph. Corrected for sea level that comes out to about 16.9. Plus that stupid track is uphill, I hate that.

anyway, i'm lookin at an LT1 right now, so maybe she'll be scooter pootin down the track by the end of the year....

 

i wish readers rides could be updated so i can put this in there.
Ok, with a big freaking subbox in the back, everything stock except pulleys, cheap open element, and the stock 3.08 open differential.
60 foot was 2.463.

I have Camaroracer1992's headers sitting in my garage awaing some minor Emission tube pluging (welding them shut), and then a 3 inch cat back with a high flow cat. I wanna go back and get timed again, then get my posi and gears and see how much better ill be after those too.

15.501 @87mph in my 4400 lb, TBI Caprice

street tires, stock converter, 1st day out

 

16.3 in my '89 Caprice.
LO5 motor, air cleaner lid flipped. Otherwise stock (3.43 rear, open diff, M+S tires). No prep, just hopped in and ran.

 

My best to date (and I will make an excuse ) is 16.99@ 81.8mph.

My excuse; I first ran my car when I bought it in April 2000 with 165K miles just to get a baseline run. No mods at all. The best was 17.09.

Then I added the Dynomax cat-back, and K&N filter and went again hoping for a lot more. That's when I ran a 16.99. But my car kept shifting at 3500RPM??? Even if I held it out, it would fall on it's face after 3500RPM.

About 2 days later I found out the throttle cable was all screwed up. It cut it's way thru the housing. Got it fixed and ain't been to the track since. And I've done a few other mods since then to.

So needless to say, I AM VERY ANXIOUS TO GO!!!!!

And to all of you running sub 15's on a 305 :hail:

I just recently got a g-tech and was really impressed with my cars performance. I know the g-tech is acurrate cause my friend ran it with his 69 camaro and it was within a tenth of his track time. My car runs high 14's at it's best. My best time was a 14.85@96mph. My mods should be listed in the signiture. If they don't appear i'll repost em. Tip for all you guys! Don't let the tranny shift for ya if you've got an auto. My best time this way was like mid 15s. Shifting manually to just before redline in 1st 2nd and 3rd gave me the best results (14s). Im now looking into camming this bad boy up. Oh, and my car has about 180,000 miles on it so no excuses for all you slow bastards.

 

Best Time: 13.8
Best Trap: 102mph
