fastest Qtr mile with bolt on's?

[msp282]

I know.... it is meant for road course....but.....

with exhaust, intake, etc..... what is the fastest anyone has run the Qtr mile in their Elise?

anyone in the 12's?

Drag race slicks. You know drag racing is all about he first 20 ft.

i don't think the elise has enough torque to warrant slicks....

anyone here run the Qtr mile???

I did a 1/4 mile run at an official drag strip last month. I have to say I was a little disappointed. I know that the Elise is not meant for this but I thought it would do a little better. I did 14.442 @ 92.7 mph. That was with a 6,500 rpm launch. One of the problems I had was when I shifted at redline in 1st and went to second the car dropped below the 2nd cam which cost me time. As you go through the gears you lose more and more power. The car just does not have enough torque to pull hard enough in the higher gears. I think the car might be capable of mid 13's if you drop the clutch at 8k. I wasn't willing to beat my car up that much. Although, I seriously doubt the Elise can get out of the 13's without a turbo or supercharger.

BTW, my car is totally stock without LSS. I wanted to get a run in with the stock set-up so that as I do some mods I'll be able to see what the differences are.

I'd say low 13 or 13 flat on NA engine and street tires. Turbo elise was tested at 12.5 by motortrend (they got 13.5 on stock elise) and forcedfed apparently managed 12.3. I still dont have my G-tech so I cant back it up lol

Unless your dropping the clutch at 8500 RPM with NO wheel spin, I'd say the car would be much faster with slicks.

I think if you dumped the clutch at 8500 RPM and didn't have wheel spin, you'd have clutch slippage. I think if the clutch didn't slip you'd have catastrophic mechanical failures.

I'm scared to dump at 5k, just feels soo bad!

14.069 @94.720
palmdale LACR could be better but palmdale has a higher elevation
arqray exhaust and reverie air intake

[keith86a]

Guys stop posting these 14 sec slips, it hurts to look at...

[aztec1382]

then post something better

What RPM did you launch at?

[msp282]

i don't think the elise spins much off the line unless you drop it at the redline.... with slicks all you would do is break an axle if you dropped it at 8500rpm....

if you launched at 3000rpm it won't spin even with bicycle tires...

"all you would do is break an axle if you dropped it at 8500rpm"

Most car magazines launched at 8k rmp to get the numbers they got, I think you will break your clutch before the axles..

[choi0706]

somebody should send me their car to launch at 8500 just to see what happens this will solve the mystery

Agreed, axles and trans can handle it. The Elise is a very light car and the stock engine doesn't have enough torque to break an axle. Remember, it's the same drive-train from the much heavier Celica GTS. That set-up isn't working nearly as hard in the Elise as in the Celica.

The weak point is definitely the stock clutch. You could probably drop a few 10th's off the 1/4 mile by just having a stronger clutch. The stock clutch slips to easily.

An 8500 launch might be tricky to pull off....you are "allowed" 1.5 seconds of time past 8000 R's per occurance.

I think you need some wheel spin to get the best launch, but I am not sure how much. If you do not spin the wheels a bit, the engine will probably bog down because the high levels of grip prevent you from sustaining 6k rpm. I have another car with lots of torque, and I know it could benefit from slicks for a drag start, as even 2000 rpm can smoke the tires. With the Elise, this is not the case.

I haven't done a high rpm launch in the Elise yet, but that is how it seems to me. Correct me if I'm wrong.

Folks if you want to get the best launch you don't drop the clutch. You bring the engine up a little above its torque peak then SLIP the clutch to keep if from bogging and if needed modulate the throttle to keep the rear tires from spinning. You want to quickly transfer the weight to the back wheels without shocking them before the rear springs have time to compress.

Now if you enjoy this you have to treat the clutch as a consumable as I doubt the stock unit will last long.

Well say what you want about tires, but IMO tires are everything. A lot of people talk about performace mods, intakes, exhaust etc.. but nothing is better than tires. The elise has good tires, especially the LSS, but I'm talking drag radials.
