my rs ran a 16.3 @ 86 mph i see people say they run 15.8's with this same mph what does this mean ?

 

E.T. is more an indication of driving skill than power. Launch, and shifting have more to do with it than anything.

MPH is more of an indication of power which is probably why your mph was identical

If you spun off the line or something, this would account for your high E.T.

16.3 stock is pretty good actually, there have been a lot of 16.5-16.8's. 15.8 is pretty rare stock

 

what all mods have you done?

 

i have a K@n lt1 cam and no cat but 2 1/4 inch pipe i had to take off slow so i would not spin for half the track......does reaction time effect you ET >?

 

ouch - All I got is a dual snorkle air cleaner (L69 style). I ran 16.622 @ 82.55 (1.219 reaction - hey! it was early, I was asleep!), with a 2.542 60' time, so if yer running 16's with a new cam, and a cat back, somethings not tuned right, IMO

 

I have got an 88 sport coupe (looks like an iroc) that is completely stock with auto. and 2.73 grears. It has 137,000 miles on it and I am pulling 16.4's with a mph of 82.9. My 60 ft times are around 2.35 and 2.4. I didn't think this was all that bad for my car. I have put an open element and I bet with just that I could pul 16.2's...

 

Nice times. That was my first time at the track, so...
Anyways, 2.35 60 foot doesnt sound bad considerin the peg leg! lol

 

Yesterday, I ran my best ever run. Here's what the slip says:

R/T ... .758
60' ... 2.354
330 ... 6.867
1/8 ... 10.620
MPH ... 65.66
1000 ... 13.842
1/4 ... 16.573
MPH ... 82.16

duhh, forgot to mention mods:

Open element air cleaner with K&N.

 

reaction time has nothing to do with et. your reaction time is how long it take syou to get the car from sitting still to out of the little electric light beams that start the timer. the et is calculated from teh time your car leaves those liught beams until it breaks teh beams at the oither end of the track.
if you have a cam and you are runnign that et and mph you have soem serious set up issues.
my car ran 15.9 @ 84.9 stock. that was with good late fall air, shifting myself at 5000, and a ton of practice hoel shots in the week i had the car befor ei made it to atco

my slip looks like this ..i have a very slow 60ft i think

r/t .743
60 2.460
330 6.953
1/8 10.609
mph 67.78
1000 13.721
1/4 16.335
mph 86.17


this is with lo3 K@N lt1 cam and no cat

 

wow, that LT1 cam really doesnt seem to help all that much. And assuming you havent done any rear work (posi, or LCA relocation and what not), your 60' isnt that bad...

 

when i was stock, i ran 15.48 @ 94 mph on G-tech. I know that the g-tech mph is off but how accurate is the time?

 

He is not getting anything from that cam because his exhaust system sucks right now. If you throw on an aftermarket cam with a 2.25" exhaust system, your not gonna notice much cause the exhaust system is to restrictive. Throw on a full 3" system and some headers and it will wake up.

 

hey 91bird305, the camaro is a very nice place for the first time! been there done that..still have the car but not the girl.

 

Hehehe, yeah Brian (Z28 Boy) said that one time and I couldn't help but think that it would be hilarous to have in my sig on this site.

 

sig, I pull 2.3 60' with my peg leg

oh ya the 15.8 was only 1 of 3 runs on stock weight and bad tires

 

16.3 isnt bad.Get a good exhaust system and headers and youlnotice a big differance.My best is 16.02 at 86.3 mph.Mods are in my sig.I only got 1 run in and spun half way through 2nd gear.

 

I pulled a 2.1 60' with my 3.42 pegleg. Does anybody care?

 

trying to help, but thanks for the sarcasm d*ck h*le

with 3.42s I'd pull them all day, and I only got a lo3

 

Uh, what sarcasm?

 

sorry I thought you were reffering to me posting my 60', my mistake, oh well nobody was hurt

 

try 2.2 60fts with a peg leg and 2.56 gears!

My ET was 16.599@ 81mph with a stock engine from the TBI to the exhaust manifolds. Oh yeah, the car is a 91 civi Caprice

 

I do not see how that's possible! I can nail my L05 off the line on that sticky track and pull of a 2.1 60'. But my point is, I'd have to really want to spin the tires to do so. I just can't see how an L03 with those horrible gears could pull that off...I believe you though.

 

Sheeeeeit Tim, I hope you were drunk or dead tired or something, because that is a record number of typos. And especially for a moderator!

I'd agree on the exhaust being the problem for TBI cars. The first mod should be headers, 3" cat, and 3" catback. Then attack the rear end with a posi and gears.

 

i iz a *** typerist

That time is off....if your car really is stock. It's not the Gtech that's off....I have one, and it's always w/in .1 sec. Where did you test this? Was the road you were on a little downhill maybe? Because I've NEVER heard of a stock TBI running quicker than a 15.9.

 

Im running 16.182 at 83.40 mph I think, lol I forgot my time.

My best stock time (sans K&N) was 16.4 at 80.40 mph. I think I can dip into the 15s if I figure out my suspenion stuffs.

 

When my car had the stock LO3, I ran a 16.1. I got it down to a 15.3 w/ a few bolt-ons and a 3.73 posi (stock heads and cam)before I blew a head gasket and scrapped the 305 for a 350.

 

My Mods: Holley Pro Jection Intake, Lunati 218/458 cam, TES, Catback, LCAs, APHR, Wonderbar, Intrax springs, B&M Shiftkit, Open 14x3 w/K&N, JET Stage II chip, 9bolt w/3.70's

The only pass I made on a Dragstrip was a 16 flat @86mph. This was before the cam and intake swap and the 3.70's, and when I was very nervous. I know the car was capable of 15.7's easy w/ some practice. As soon as I get a chance Ill get some new times with the new cam, and intake.
