:rolleyes:

Neil doesn't hit the switch until he hooks up, meaning he's at LEAST Above 4k rpm when he does.



It's a front driver, and it's a family sedan obviously NOT MADE for drag racing. Gimme a set of slicks, and I'll show you a 2.0 60'.

Like I said, low-end torque HELPS right off the line, but it's not necessary, to a point. Tell that to the guy with a Celica GT-S running slicks, race clutch, intake and exhaust running a 14.2 @ 98mph. How much torque does he have? He was ripping off 1.9-2.0 60' all night long.



He mostly has mid-range and top end power from about 4k-7k, which is what counts. And he's not in the 13s, he ran a 14.09 @ 98mph or 99mph.

FOR THE LOVE OF GOD A CELCIA GTS WEIGHS 2500 POUNDS! drop 700 pounds off the tour and you better be running sub 2.0 60' times. WE NEED MORE TORQUE! i am not saying more top end won't help, but until you have the bottom end you are wasting your time building up the top end of the curve. face it, all the facts point to more torque, all the bs points to higher top end. and i am almost 100% sure david z has hit 13s, but that is beside the point. he is the closets to 13s on this board (if he isn't already there) and he has the most torque, and if you look at this cars torque curve (3.0 or 2.5) IT IS FLAT, meaning he does not have more in the top end of the curve then the bottom, it is real close all the way through. bottom line is, torque moves the car.

I might have aused 3.73 for ya soon. I am going to 4.10 as soon as I find somewhere to get my rear end for the Capri rebuilt. I have an 8.8" for her, just no one to do the rebuild.....anybody you know do it?

Well, forgive me, but I thought we wete talking torque vs HP. And how much torque is that shot giving you when you hit it in second gear at 3700 rpms? Not no damn 30+ ft/lbs...

but i say no one short of 400hp will be consistantly hitting 13s without 400hp

You know what, I pray I hit a 13.99 this next track trip. With only a 100hp shot, and a few minor mods, none giving any torque, unless you count the chip.

And that statement about catapillers, just goes with the overall atitude of this board, ignorant and childish.

Just a fact Bret.

Quote:

i never relized how childish most of the people on this board are until i started checking out the f150/svtperformance boards.... people are so much more helpful and mature. they don't have this "if you don't agree with me i am going to flame you make useless childish commements until you do agree with me" instead they provide facts and technical data to help you understand where they are coming from.

Bret, you two cents is usually not facts, and/or technical data, it is usually your opinion. You are the one who is pissed here, not me. When I get my car into the 13's you'll be the first to know, trust me....

For the love of god, a Celica weighs 2500lbs, without the driver, plus another 200lbs for the driver, so your difference is 500lbs. GT-S has 'measley' 130lbs of torque mind you....



Yes, but we need more TRACTION.

In theory, low-end torque certainly won't hurt, but you need mid-range and top-end power.

Judging by your first couple of posts, you said that all we need is low-end torque to get 13s, that's what I was trying to argue. IMO, we need traction more than anything else.

If low-end torque is such an important part of getting low ETs, how is a S2000 running 14.0-14.1 with barely any torque? How is a Civic Si running 15.0-15.2 (slighly modded) with almost no torque? (sorry Infuryum. )

Again, I want to reeiterate that low-end torque certainly won't hurt, but getting traction is more important when it comes to our cars.

Look at SVT2000, running a 14.7 with a 2.1 60'. Just shows you how much of a difference traction can make.

And lets not forget Brad Noon's run of 13.9 with a 75shot... 2.1 60' with torque straps. Think he hit the switch right off the line to get more of that low-end torque? Fugg no.

John

got get your car on a dyno, nitrous makes gobs of torque... you think that "kick" you are feeling is increased hp?!? that is torque my friend. the huge increase in torque is why you have to ingage the shot so late in the rpm band, so the car has time to grip the road. oh, and i hope you do get in the 13s, you will just reinforce my point that you can't get into the 13s without more torque.

oh, i guess svt drivers have 0 weight

and the S2000 weighs in at like 2800lbs, and it has 150lb/ft of tq. weight is a very important factor in 1/4 times... it has roughly 85% of our weight and 88% of our torque plus another 40 ponies to boot.

lets get back to talking about the csvt... and i guess i should correct myself, this car needs more torque over all, but considering the torque curve, more low end = more mid and top end tq

My car tips the scales at 3225lbs with me in the car.



Exactly, and those 40 ponies are only up there in the 7-9k rpm range, proving that top end power is necessary for low ETs.

John

i never said hp was "useless", but it takes more then that to get the low numbers, and i wouldn't exactly say 14.7 is a low et.

Well, you did say the following:

"everyone is so worried about peak numbers and how much hp they make a 7500rpm. who cares. you aren't going to break into the 13s with high peak numbers"

That's pretty much saying top end power is useless. But whatever, think we've already reached a conclusion on the subject.




What? 14.7 is an extremely good ET for a nearly stock SVT.
