I'm kind of dissapointed, figured with all the mods i'd do better, but this was the first time ever racing and it was hot out. i had 2 runs before this with 14.7X times,, the first run i went 94mph, second i went 91mph, with the same 1/4 mile time.?? whats that mean? I also had on drag radials.. on my last run i got the rpms up to 1000 then launched, i guess it helped,, shaved off .2
let me know what you guys think about the times and what they mean...
i need to advance my timing, hopefully thatll give me more power..

What elevation is the track at, and how hot was it? Both of those things could make your ET seem slower than it is. My only reccomendation would be to launch at a much higher RPM. When you're sitting at the lights you should have your engine at the highest RPM you can before the back tires break loose, which with a stock converter would probably be in the 1200 - 1500 RPM range. That way when the green hits, you lift your left foot off the brake and nail the gas with your right. You should see the difference in your 60' times. Look at your slips from the off idle, and 1k RPM launches you made. I guarantee you most of the .2 difference you saw is right there.

I think I'd like to race you for money, even with my slower car.

Gotta work on the RT, Ron

 

Dont wait for the green like the above post says....you are sleeping at the line. Leave on the third yellow. 60ft should be much better with drag radials...I get that 60ft on my street tires. Make sure you are doing a full burn out, and launch at the highest rpm possible.

i think the track is at sea level, the temp was like 80*..

yes i realize the reaction times suck, but this was the first time ever at the track,, i had no idea what was going on.

thanks for the info guys

 

you should be running WAY better times with those mods....check out my response on the "13's????" thread...

Hmmm, seems ok, but you should be a little better. Add some fuel. Don't worry about reaction time, ( I have no idea what these guys are talking about) that doesn't matter. Clock doesn't start until you trip the beam. You go when you want to. Get some diagnostic software and see what is happening. I think you should be having a higher trap speed than that. What is your timning set at? A 2.0 60 isn't that great either, but what can ya do on radials? Get some software, run it, and give us the info on what is going on and we can better help you.

Ron was looking at your mods and was wondering do you have headers on there?

 

What happens when you hit 88 with that setup? With that flux capacitor the time travel might be slowing you down

Oh no, it's the Libyans!!

 

the conditions were fine...I ended up running a best of 14.59@93.xxmph that night...I actually talked to Ron for a few mins about his car...his car is probably a bit heavier than mine but other than that I dunno what was up with his ride. His 60's were much better than mine by about a whole tenth so really he probably shouldve been running 14.4's or better but as u could see his mph wasnt quite there to get the job done. Anywayz...

Let's see, we both line up, I have a .8 RT, Ron has a 1.2 RT. Ron runs 14.6 and I run 14.8.

Who wins the race?

That was my point, albeit with just some good natured ribbing.

 

nope, no headers


i had it a 1.00 jigga watts, not 1.21, so i was fine. it might of messed something up though, ill check into it


my first run , i had a 14.7 @94mph, higher speed but lower time, why?
timing is 6*- stock
i had on drag radials, not regualar radials

Nice shootin' New!

If that was recent, you should be even better when the humidity improves. O.K. What's the latest mod? That's quite an improvement, and very nice for stock exhaust manifolds! Get the 1.6:s installed? Just curious what it takes to get the 305 tweaked...

Ron,

Don't sweat the reaction time. You are racing the clock/traps at this point, not the guy or girl in the next lane.

Your time SHOULD be a bit better. Have you played with the TV cable setting to max the shift points? If you're over-revving and gasping for air at 5,000 RPM shifts, you could really be hurting the times.

Also, don't be afraid to bring up the RPMs at the tree a bit more - it can help get the power to the wheels a lot faster.

On the bright side, you're already beating most of the Mousetanks you'll encounter on the streets, so it only gets more embarrasing for them as you improve the launches.

Nope, I didnt do the 1.6's. All I did was find that happy mixture of fuel pressure 44.5 psi and timing 11* advanced. I also did the TB bypass. The run was on Sunday June 3rd at Byron. I bought a 350 to rebuild but scence I got the 305 running well so I'm going to slap a set of headers and see what happens (14.0 I hope). Just to let you know what Vader is talking about with the same mods at the begining of the year I ran 15.0 @ 89.5, So I droped 4 tenths and gained 4 MPH with tunning alone. The leson here is if you go to the track do just do run after run hoping to get faster. After each run go back to the pits and make some adjustments. Everyone can and just there timing and if you have an AFPR there it is.

i adjusted my tv cable that morning, but i noticed when i was racing the rpms went up to like 6000 before shifting.. why is that?

 

hey new87 you should be running better than that. my 305 5 spd with the stock cam and heads, and only headers and gutted airbox, screens off the mafs, and no cat runs 14.48 @ 95 on street tires with 2.2 60ft times.
do i just have a freak or something?
i do have 3.08 gears but not much of a difference between that and your 2.73
Andrew

 

Your stock cam for the T5 has a lot better profile than the stock cam for the automatic. Your stock cam profile is not that far off from the mild LT1 grind. And your rear gear ratio is quite a bit better for acceleration. 3.08 vs. 2.73... that's a 12% difference in ratio. That would be almost the same percentage increase between the 3.08 and the 3.43. Applying that math would indicate that his setup should do 12.83 @ 104.6 MPH with your gearing. Granted, the difference is not a direct subtraction, but the better gearing certainly helps you get in to the power band sooner, and he's running a stock (non-ported) intake and cast iron exhaust manifolds. The only real changes are a mild LT1 cam, a few free mods, and his tuning efforts - pretty good for a "lowly" 305 automatic in a plain wrapper.
