BPU evo IX vs 07 RS4

[ihatepotholes]

a guy i met at a bar just challenged me to do a friendly run with his brand new 07 RS4. i know nothing about these cars, im quite sure they r pretty quick, i'd like to hear what u guys think. i drive an evo ix with basic bolt ons, reflashed and tuned. im at 350whp and 335wtq on a dynojet. haven't been to the track yet, people with my set up usually trap around 108-112. so lets hear what u guys think

If what you say is true, your car is running around 460-470 hp at the flywheel. I'd say that is a bit optimistic with a few bolt-ons and an ECU remap even for an Evo IX.

Having been in the Evo scene for years and having had a modified VIII MR, quite a few Evo tuners are "generous" with their figures in order to satisfy customers. Tell us what mods you have exactly. In terms of your quarter mile terminal speeds, again that really doesn't tie together with a car putting out 350whp (unless you're really heavy!). I'd be expecting your car to be doing high 11s and slightly higher terminals than that.

As far as the RS4 is concerned, it is heavier than the Evo IX. If you were to go up against it in your standard IX GSR you wouldn't have a prayer. In your modded car...if the figures you quote are true, you obviously have a significantly better power to weight ratio and would edge it to 100mph. Beyond that, I'd foresee the RS4 reeling you in.

A better test of real world performance is the 30-130mph acceleration times. RS4s tend to cover this in 13-14s. Based on the last lancer register 30-130 day....Evo VIIIs and MRs running 410-420 HP at the fly, can manage around 17-17.5s at best. This is due to the Evo's poor top end and rubbish aerodynamics.

The bottom line of the above is that the Evo would need a significantly higher power to weight ratio compared to the RS4 to even match it, let alone beat it.

i do NOT run anywhere near 460-470 flywheel horsepower, stock evo ix usually dyno around 260-270 on DYNOJET. they r 287hp from crank. drivertrain loss isn't significan. around 400 horsepower from crank im thinking.
currently im at 346whp/335wtq, i haven't been to the track yet, but i did rape a 305whp supercharged s2000. thanks for the answers!

how fast do rs4s trap?

[simple1]

If you mean how fast are they over 1/4 mile............... the answer is 11.7 seconds average, but obviously that is taking lots of other factors into consideration, including driver skill and reaction time..... B7 needs very careful launching, or else four or five side step launches will kill the clutch.

What is it with bar room debates about my car is quicker than yours.....

I'm not sure who is calculating your flywheel horsepower but 346 wheel horse power is a lot more than 400 HP at the flywheel. If you estimate your car has around 400 HP at the fly, your at the wheels figure will be around 300-310 whp. A 300+ whp S2000 would easily wipe the floor with a similarly powered Evo due to several factors:

1. Better aerodynamics
2. Less transmission losses

The only reasons you'd beat him would be:

1. He launched poorly
2. He couldn't put the power down on the tarmac/traction issues

By the mods you have, I'm guessing you're in the USA....notoriously known to produce extremely over-inflated horse power figures from your dynos over there.....no offence, just telling the truth.

I own a evo9 in sydney australia, Im pretty much sure that witha few bolt on mods the evo can be a killer, I know that here they already have kits that make more than 40% extra power for very little money, that would mean from standard 300hp to about 400-450hp. which isnt bad for a little 4cyl engine, and as for asking questions about trap speed and 1/4 mile, its a bit stupid as every car runs different, some have quicker take off with lower trap speeds yet run faster over all 1/4 mile times than cars that take off slower and have more top end power to bring thier speed up with higher trap speeds.

for example, i had a nissan gtr that ran 10.8 at 1/4 with 121mph trap speed, and the car that i was racing was a very fast V8 that ran 13.1 with the same trap speed, which means that my 4wd launch was my only advantage where his top end was much better.

i think all in all the rs4 will win as the evo cannot be launched over 3500revs in tarmac mode, and 4500 in gravel mode.
good luck to you anyways
