1/4 mile time and mods

[JoshCrane1]

Hey guys what did you do to your tc and whats your 1/4?

[JoshCrane1]

Heading to the track soon for the first time and i wanna kinda guess how fast i will do it
Megan headers, weapon r short ram, agengy lightweight crank pulley( not underdrive), twm stage 2 short shift, and motegi dp12 18" rims wrapped in nittos. I heard just changing from stock tires makes up for a few tenths. But anyways, if you could let me know what you all think.

15.6 if you drop tire pressure and semi know what you are doing, thats because you obviously are new at racing.

[JoshCrane1]

I was under the assumption that stock tc's do about 15.5 plus or minus 2 tenths, And assuming i know how to race, just never been to a strip. i was guestimating around 14.8 or so

I doubt youll hit a 14.8....

Stock tc's with a very good driver stock hit 15.5 with proper setting of tire pressure and such... its not a car off the truck.

[_Keith_]

And since you so call know how to race... but never been to a track I still say 15.5 15.6.... Alot of tenths are lost on the launch at a track and its all about a good reaction time to help you down the track.

This is where i got the numbers, it seems a little quick, but they say that all numbers are published by 3rd party testers( car and driver, motorweek etc). THats why i wanted your guys to chime in. 15.5? even with those mods, you may be right, sux balls.

[Nebster]

no, stock tc's do like 15.8 if you're a good driver.

first time i went down the track i had a 16.2 you'll get 15.5 ish if your lucky. the weight of the 18's don't help you

[JoshCrane1]

yeah bigger wheels slow you down, more rotational mass, thats why i just went with 18"s, but i figured going from those sorry excuse for tires,(potenzas) to nittos would make up for the increase in rim size.

[Nebster]

meh maybe. hard to say. may make up but it would break even.

let me just say i wouldn't consider your 18's a performance mod to decrease your time

[JoshCrane1]

thanks for the help yo.

[hotwheelsrs1]

yeah those times published by car & driver, and motorweek, are with profesional drivers, and are most likely exagerated on top of that. no way u will break 14, especially on ur first time on an official track. its much more different that screwin around light to light, u need to stick to the groove and lauch just right, cause tourqe steer is going to be crazy on a prepped track. but goodluck.:up:

[2dot4]

in all honesty - his 18's probably weigh around the same as the stock 17s. The stock tC wheels are heavy as hell. The nittos will definitely help with the launch (if you know how), and with all the mods, I'd expect maybe a 15.2 if you know what you're doing - this is coming from what I've seen. I've seen bone stock 5spd tC's run 15.5s consistently. It's not hard if you know how to drive and launch the car. I've also seen tC's with your same mods and a 75 shot of nitrous run 14.6 in an auto tranny. If you drive it like you're pulling away from a stop sign, don't expect any lower than a 16 second run. The launch is the most critical part of a 1/4 mile run. Your tires will help, but you gotta nail the launch.

for hp sake, I had a weapon r intake, crank pulley, header, and s-pipe on my auto tC and added 27whp on my auto tranny. As for a 5spd, you'd see better gains - possibly 35whp extra? With that said, I'd honestly expect a 15.2 if you drive the car well.

Let us know what you do - I'm interested.

I/H/E i pulled a 15.0 @ 93 MPH on 19's

Full ZPI Turbo Kit @ 14 PSI ? Havnt ran it yet

[Whocares05050]

Stock, i pulled a 15.5 with 200 miles on the car

[2dot4]

Full ZPI Turbo Kit @ 14 PSI ? Havnt ran it yet

by "full" do you mean stage 1.5?

[JoshCrane1]

thats pretty good mike, you must hit up moroso pretty often, and if im correct those 19"s you had on there could of easily cost you a tenth or two. with those numbers i feel a little better about trying to break 14 with a few more tweaks.

Timeslip scan? I am curious what your 60 time is to get a number like that, especially with 19's.

I have been drag racing since I have had a drivers license. With my bone stock RS1 (came with 18's), my best run has been a 15.686.

In order to make it into the 14's consistently, you are going to need around 190-200hp with our heavy tC's.

I am glad people are doing this on the strip though. It makes me feel warm and fuzzy knowing people are racing at the strip where you can back up your claims rather than on the street where you can kill the other people out there. :up:

[JoshCrane1]

Thank god for race tracks, but there needs to be more of them.

i just went to the track this past saturday and ran a 14.8 stirpped interior full rice mods if you dont know what that means its intake and full exhaust. reaction time of .236 and a 60 ft of 1.8 trap speed of 95.7 mph the gtp i raced ran a 13.8 i knew he meant buisness when he took out his drivers side headlight..... probably best launch i have ever had...... it was fun.... but on an average i was running a 15.00 so unless you had your car stipped i dont think you ran a 15.00 on 19's

[JoshCrane1]

Lets all keep in mind assembly line tolerance of hp is <15 hp. Maybe he got lucky and got the one off the line that was maybe 170 hp. Its the luck of the draw, and ( its a stretch) maybe how you break in your motor in can effect your overall baseline. So in tard terms, one stock tc vs. another stock tc, the times wont be the same, its just a matter of how much.

I know that GTP. He is always at the track. Extremely quick car.

If you are getting .236 reactions, you are probably waiting until the light is green before going. You should launch as soon as you see the yellows go on (if using pro-tree starts).

And was that 14.8 with the nitrous? I remember the last time we raced, you ran a 14.7 with the juice.

So in tard terms, one stock tc vs. another stock tc, the times wont be the same, its just a matter of how much.

Assembly line tolerances are closer to 5-7hp at the crank. If I remember correctly, stock tC's off the showroom floor make 137-142hp at the wheels and that could simply be from using different dynos.

If you put the same driver in 10 different stock tC's with approximately the same mileage on them, you will get 10 very close times. The 5-7 horsepower difference won't affect the E/T's more than .05-.1 or so.

That is what is great about drag racing. If you have the exact same car, the better driver will win 9 times out of 10 (even pro drivers red-light or mis-shift every once in a while :razz: )

[bottled]

actually tony last time we raced i didnt have my nitrous bottle filled..... the difference between that race with you and this one was my 60ft time when i raced you i had probably one of the better reaction times of like .06 or something and i think yours was even lower than that...... and my sixty foot was i think .1 sec faster than yours.... or somthing.... im waiting to get internals before i run nitrous again just due to the fact that i want my car to last and im getting married so money is short.... and my freind just gave me his 93 240sx.... and im trying to get an s15 engine and 6 speed tranny swap for that.....not to mention the recent purchase of a house so i dont got time really anymore.... but no i ran a 14.8 without nitrous...... and just so you all know TONY has gotten the fastest time ive seen from a bone stock tc..... He definetly knows what hes doing at the track

[bottled]

oh and the reaction time is from the flag girls.... cedar falls got purchased by cordoba raceway this year i guess... and now they do the stage stage GREEN it blows.....

[2dot4]

...and a 60 ft of 1.8

I would love to see a scan of that time slip - my buddy has a 350whp Evo, and he runs a 1.7 60ft on a good launch.

He might be rounding up and you might be rounding down, but a tC and a 350whp Evo shouldn't have the same 60ft.

[bottled]

actually on slicks its amazing wat can be done...... and i bet that evo had a bunch of tire spin.....even with awd...... unless it was running slicks... then he just wasnt launching at a high enough rpm

[THansenite]

Yea, this year they have flag girls later on in the night. It freaking sucks. Ohhhh, eye candy....whooptie-fucking-do. I paid to race and get actual times, not to get flagged starts. I think you, me, and almost all of the other racers would prefer starts go back to the way it was last season. Racing last season was much funner than this year since the acquisition by Cordova. And good idea building your engine before going nitrous again. :up:

[bottled]

ahh the flag girls dumbest thing ever.... gets the crowd going.... but i dont care my adrenaline is pumpin and i dont want to see some whore waving the flags thats for sure...... but i do miss the juice though..... it makes the car fast.....i got all the direct port stuff i need to do it.... its just i get get stupid with the amount of shot i want and would end up blowing it up.... once i get it done i want a shot at ben......see whats better NA or boosted well atleast here in iowa.... i know there are tons faster boosted tcs in the states

14.315 @ 96.53 MPH.... Turboed Auto tC with Drag Radials.

[2dot4]

I just wanna see your time slip.

The 1.7 second 60' was his best run. He said he usually pulls a 2.0 flat. And if you've driven an EVO, you'd notice how difficult it is to spin the tires - especially on a flat, dry 1/4 mile track. You'll spin your slicks before he spins all 4 wheels.

And launching at higher rpms guarantees wheel spin - not a faster 60'.

[Krdshrk]

I'm calling BS on the 1.8 60', unless you're turboed and have drag radials or slicks. Munch runs 1.9-2.1 60', and he's got the power and the experience. I don't know if i've ever seen him run a 1.8 60'..

[THansenite]

Yea, my 60's are usually around 2.3 or high 2.2's on occasion. A 1.8 60' time seems a little quick for a car on street tires and no LSD.

This time is the S/C tC

[Krdshrk]

Most stock (or close to stock) tC's on the track i've seen run mid 15's. With the S/C they can break into the high 14's. With practice, drag wheels, and some other supporting mods, they can get to low 14's.

[Krdshrk]

That's their custom turbo kit with race gas....

It's doable with the proper tuning and pump gas as well... Munch has broken into the 11's.

[JoshCrane1]

keep it up hp freaks!!!!:evil:

When I get a new motor maybe ill put some money into it.. not to trusting right now of toyotas motors............ :mad:

Dont need a new motor, just new internals, unless of course you broke a connecting rod or something and punched a hole in the block. In my opinion toyota does the best engine tweaking out of all the manuf. destroying toyota motors is way hard, and crazy, if not using excessive boost.

[Gymo]

A stock Tc at BEST can do 15.1, completely stock, thats official!
