13 second quarter-mile shenanigans

Alrighty, weigh in on what you think a 240 needs to run a quarter-mile under 14 seconds.

Modded AW71, 15g running 20psi?

if you are on i roll volvo australia fb page tag mitch budd and ask what his 240 had done , it ran 13s ..
from memory it was a pretty basic thrown together setup .... 740 turbo gear, m47 box, 2.5 exhaust .. think he was running around 16psi

Stock AW71 is amazingly fine with the power required for a 13 second pass
19T running 19PSI and E85 and Lh2.4 with 3" AMM and 45lb injectors and a better than stock IC
Drag tyres and a good launch

have you tried stripping it of all interior and body panels?

How much power would that setup be making?

I missed adding in a better than T cam as well...

Assuming lh2. 4, a 15g may crack a 13, the diff ratio is a bigger factor there. My wagon with a loose wastegate, ported 90+(proven to add 10hp) with a 3" exhaust, stock ic and dying aw71, lh 2.2 and ipd turbo cam in a wagon weighing 1650kg, ran a 14.4, I couldn't get faster at the time, and every time I've had a good working auto. I have had no time to go back. And autos die when you start doing valve body mods too.

I think the box will die, especially if no oil cooler, and as is, your 240t would run a mid 14. Dave on here selling the 240 is the one that has the car that runs a 13? It has one of my intercoolers too.

I have the car. It went 14.1 I think, pretty sure the slip is in the glove box still. Atm it doesn't feel capable of that.

Whatever you need it's probably easier than getting an 850 into the 13's

A power to weight ratio of about 170 BHP per 1000 kg or better, and work on reducing the drag coefficient.

Reduce pizza consumption, got it

Just spoke to mitch it ran a 14.3.
he feels if he had an lsd, stiffer shocks and a better clutch he would've hit 13s
only mod was a 2.5 turbo back exhaust

pigdog

shit i have no idea @heavy_dd what turbo is in your car ?
he said he was running 16psi too

It's cheaper to shed weight than to gain horsepower.

To run 14 second quarters, about 160 BHP is required per 1000 kg.
To run 13 second quarters, about 200 BHP is required per 1000 kg.

Increase the weight to 1400 kg, and about 280 BHP is required for a 13 second pass.

Keep the fluffy dice, doof-doof boxes and the like, and about 320 BHP is needed to do 13s in a 1600kg vehicle.

Holesaw, or Holset.

The rules allow some scope.

Mitch's car was a basic +T with exhaust and one of Alex's intercoolers.
