Naturally Aspirated 1/4 mile time

[99CamaroBullet]

Quick question.... I have looked at the 1/4 mile times for our cars. Is it possible to make our cars run low 13's N/A?
I wanna try and make my car run with LS1's without a Supercharger or Turbo. Although I am sure for the money it would be cheaper to drop a LS1 in my car. But, there is still something in my mind about a V6 taking it bigger brothern, w/out a charger or nitrous.
Is this even feasible? [img]graemlins/burnout.gif[/img]

one guy ran a 13.6 N/A but I think he is getting borderline streetable.

Hey Eric , I know you know alot about the 3.4 so what would you think my 3.4 could run with the supersix powerpack but with bigger cam specs with Crane Cams Gold Race Extruded Full Roller Rocker Arms - 1.6:1 Ratio with High energy pushrods , and my mods in the sig?

[StockV6Cam]

Speculation on mods on the 3.4 is hard considering anyone who's actually done those mods has yet to see the track for some odd reason. That or the people who have done similar things went to the track and ran sh!tty times. But after I have the PowerPak on my car I'll see what I can muster. I'm lookin' for low 15's. Maybe with a few of the other mods I've been picking up I can nail a 14 n/a [img]smile.gif[/img]

I dont get it?? Why only expect low 15's ?? If the power pack is not gonna give us a good 1/4 mile time then how fast would our 3.4L's be from a roll? Would we be able to take V8 mustangs, V6 eclipses , or integra type R's , Ect. from a roll? Will our little 3.4's at least have some top end power to them with the power pack you think?

[MustangEater8251]

I hope they would have more top end power, one of the biggest things with the 3.4L is the heads and cam, and hopefully SSM takes care of that.


I do have no idea what cars will run... but if it makes you feel anybetter, the 3 guys on the timeslip page all were making more power than me, I jsut got a better run [img]smile.gif[/img]

Especially Tim Legros, he trapped 91.35mph, thats nearly 5mph faster then me with the same gears. He might have been able to dip inot the 14s, i think.

Because I'm thinking conservatively. Running low numbers isn't as easy as it seems. If I could run a 15.0 that'd be a full second drop from my average times. All will be known shortly.

Alright thanks for setting me straight guys :D

It is possible. It will take lots of work and trial and error stuff. It would also require you to swap that M5 for an A4.

check sig.

Why the tranny swap? I know most of the fast cars on this board are A4s, but why?

[ravenp]

I want to take a stab at this one [img]smile.gif[/img]

Drag racing our cars boils down to the first 60 feet! Our cars don't put down enough power to the ground to make up for a bad launch in the last 1/8th like an LT1/LS1. You'll see them spin into 2nd and then stick and shoot down to a 13.6 without breaking a sweat.

Our cars rely heavily on a perfect launch, zero spining and torque multiplication of an aftermarket torque converter can seriously help that. That's why the convertered cars are dominating the n/a list at the top.

The M5's don't have the torque multiplication factor at launch, and it's harder to stick consistantly with a manual.

I hope I got that right...

[Magnus]

A4 shines because of the torque converter. Not only are you in your power band without bogging right off the line, your RPM's are slipping higher than a manauls all the way down the track thus putting you in a higher HP zone. Shifting at 6K my car's RPM's come down to around 4400 or so and I'm still making good power. In a manual they'd probably come down to 3900 or so.

[MustangEater8251]

ehh I prefre my factor M5 converter, of using the your feet to featerh a good launch.


It can be done in a 5-speed, you jsut are going to need ot practice and get your launch right.

my theory on the fastest guys are A4s, most cars with options come in automatic, especially anything GM has, now think what do options cost? Money, so the owners have money, where do the fast tiems come form? money.


I have OEM clutch,ellegally bald Cooper Coibras(235s) stock shifter, cracked torque are, and my 60s' average faster then about 90% of the v6s around, and most are putting out more HP then me.

[Magnus]

Throw an M5 in my car and the best driver in the world wouldn't be able to hit 13.6. You'd have to drop the clutch at an extreme RPM and shift instantly, but the way the locked clutch brings down the RPM's after the shift just wouldn't be enough to accelerate the car fast enough..

A slipping converter helps you stay in the upper RPM's.. the key thing is you have to build the car to make power up there.

My next NA setup will probably never dip below 5000 RPM's at the track.

[Slow-N-ugly]

Got to disagree here, I can shift (the 1-2) at 5500 and not drop past 4500.

On crappy skinny tires (245, 60), with no burn out I was able to get a 2.4xx 60ft in three runs. That's with all stock suspension and 70,000 miles on it.

If you check I am guessing the fast cars all have some if not a lot of rear suspension upgrades, as well as the front sway bar removed for weight transfer.

The reason for an auto is consistency; the converter helps out of the hole by not putting al the power down. An auto is not as efficient as a manual, but for the most part it is more consistent and much easier to drive.
