I find these numbers interesting. I don't think my chip is giving enough on top end. Also, the car was running at 230 farenheit with a full tank of gas and no wieght reduction. What do you guys think? I think it should atleast be in the low 13's and eventually into the 12's if the chip had some more work. With the T56 I shift at 5000rpms and it kicks down to about 4000 rpms. I'm assuming I'm getting the great 60 foot times because the computer is feeding the engine correctly till about 3500 or 4000 and then, the rest of my 1/4 is between 4000 and 5000 rpms. Of course, my computer doesn't give the engine any power there so my acceleration slows significantly. That's what I'm thinkin.

Dang dude! Clicking of 1.55 short times ain't bad. What you got for a suspension?

AlkyIROC

Unless you're dumping the clutch at 5000 rpm and have 26" or smaller tires I doubt those 60 foot times are correct. 3.73 and an open diff might see 1.9 or 1.8's but not 1.5's. Your engine just doesn't produce enough torque for your setup to get those numbers. Go back on another night and try again. It's possible the tracks 60 foot lights were wrong. I've seen it before. The computer gets screwed up and gives all kinds of wierd readings.

A 1.5 60 foot time is good for a car that runs low 11's not high 13's.

That's my point man. My car SHOULD be running high 12's NOT high 13's. Yeah, I know it's TBI and all, but it does have power. If the vortec crate engine is any indication as to how much power I have I will be in the 12's if I get the computer straightened out and the temp down. Not to be a *****, but the numbers had to be correct and my car does have enough torque to do what it needs to do for a 1.55 60 foot time.

hehe. I didn't check your sig and didn't notice the Vortech 350 crate motor. Steven is right... there's no prayer you ran that kind of 60' time. Go back to the track and try again.

Birmass

It's actually not a crate motor. I built it myself. It's got the heads with edelbrock carb intake, adapter, and 670 TBI. The cam is also significantly larger. The lift on the vortec is .435int/.460exh. Mine is .471int/.491exh and the crate runs 330HP so I better be around 350 with almost 400LBS of torque.

You guys just can't imagine TBI doing something can you? It'll be a 12 second car with tuning and it will stay TBI .

Tell you guys what. I'm a pretty honest guy. I'll be hopefully going to the track this friday again and I'll update you as to what happens. If I'm wrong I'll tell you what it actually ran, but I hope I'm not .

Okay, sounds like a plan Don't get me wrong... I'm not knocking your setup. I'm just giving you my honest impression.

If you do it again I'm going to have to know your secret. I've never seen a stick shift, one-wheel drive, 3.73 geared, full weight, 350 Hp, no roll cage, possibly no subframes, stock suspension vehicle do that. Unless you give me a picture of you pulling one wheel clean off the ground...

That 1.55 short time is possible with the right tires and a clutch dump. I've cut a 1.84 with street tires and stock suspension, and a friend with a vigilante and 3.73's cuts 1.6X's all day with drag radials.

Sounds like the motor is falling on it's face and running out of air/fuel at half track. You need some intake and airflow mods bad.

Birmass

Thanks guys. I appreciate the input! I'll keep you updated.

If you are really pulling 1.55 60ft times with an open 3.73, you will be a very rich person selling that secret.

With those short times, you should be 330'ing in the 4.8x range, not 6.x range.

I would say there was something wrong with the 60ft clocks.

What track are you doing this? Capitol Raceway or MIR? My red mustang (danjrus)at MIR gets 1.57 short times and it pulls the wheels off about 6-8 inches. It runs M/T slicks and some suspension mods with a full cage. My son drives and he leaves on the limiter everytime. I don't go to Capitol because there is no traction.

I think the 60' timers at the track that you ran at were way off like this run that I made at Thunder Valley in Noble Okla.

This run was made before a few of the mods that got me to the 14.3s. If you take a look at the 60ft time you know by everything else that its bogus. I usually get a 2.10 60ft. time.

Look at your 330 ft time on your first listed run -mine is quicker than yours... How is that if you really ran the 1.55?

This is at capital. I hate to admit it, but there probrably was something wrong with the clocks, but I can dream can't I??

Anyways, I would like to emphasize that this is not really a 14 second car we're talking about here. I've gotten a friend to do about 12 chips so far and it could go all the way up to 100 chips before we even get close. Think of it this way, my 1.55 time probrably isn't right, but my car is DEFINITELY not a 14 or even a high 13 second car. The regular vortec crate motor makes 330HP. I built the motor and I have a bigger cam in it too. I would atleast hope I'll be pushing 350HP with 400lbs of torque. Once I get the tuning doen with the chip there's no way that this is a mid to high 13 second and up car. Remember also that it's a T56 which affects my usable rpms in the 1/4 mile. The car is a work in progress and it needs a lot of work. But I can still dream that it'll do a 1.55 60' .

There is a BIG difference between a 1.8 60 and a 1.5. You'd need mid 11's to hit a 1.5. As far as the motor goes, check my sig, I should be making more power, but only hit 13.5's. These cars have por ability to get thte power to the ground, because of the rest of the driveline. So don't expect 12's. You can probably get mid 13's and maybe even mid/low thirteens, but realize that a 13.2 would take roughly 70 hp more than you are making now. Also, you'd probably need atleast 106 mph, to hit a time like that at the very least. Godd, luck, I'm sure it'll pull a mid 13. That's not bad at all.

Thanks Justin. We'll see what I can do to get it down there. This stuff can be frustrating at times, but if you succeed it's all worth it. I'm gonna keep trying and if I can't hit 12's by messing around with what I've got then I'll add something else on to get it there . But no nitrous!

nicmike85

Occasionaly you can get what we call a rear wheel start. Did this one time with the pro bracket car and pulled a 1.08 60 foot when it really only pulles 1.48. That info was useful though cause now we know where the car is at 0.40 into the run. Incase we want to juice it while the chassis is at 100% weight transfer.

wow you lucky bastard! When I was hitting 14.9 my best 60' time was 2.4! **** 1.5...If only I could do that. Probably hit low 14's. Hell...maybe high 13's? hey a guy can dream. =D

yea i got a time slip once that said i pulled a 1.02 60 foot time and a 3.7 1/4 mile pass @ 101 mph. That was a really good pass. but i thought i was going to brake out so i hit the brakes wich brought my mph down from 400 mph to just over 100 in 10 feet. dude the clocks we messed up. You are not coming off the line well at all to run those et's at that mph.

Your 1/4 mile speed indicates about 240 HP and I don't believe that you have a true 1.55 60'. This is especially true with a T56 vs an automatic.

Well if any of you are lucky enough to turn a 1.5 60ft then that would put you in the low 10s

Basett_Racing

Low 10's...uh...It would take a little more than 1.5's to get there, unless it were a 9 sec car, with a traction problem. Low 10sec 60' times are generally more like low 1.4's or high 1.3's.

Oh yea. Sorry. We had between 1.42 and 1.53 and we had the timing cut back trying to kill torque. You know some of that brackett stuff. Most of the guys just want to go faster but we always went more rounds.
