I hadnt seen that...but you are right. so by 120 mph, each car is just as fast, then from 120-150 the manual car gains a 1.7 second advantage. thats a pretty good difference IMO in 30 mph. so the m3 manual on average is gaining about .6 seconds per 10 mph incremenent after 120 mph.

 

If the M3 is at already over 100hp per liter, just how much hp are those mods going to add anyway?

 

Very impressive!

 

Uh, you are comparing numbers from cars tested with different drivers on different days. Car and Driver did not test the DCT and manual on the same day, they compared the results to one's they achieved previously. We know how much tests can vary from month to month. Just look at the numbers Road and Track has gotten. If you compare their DCT times to their manual times one manual M3 went 12.5 and one manual M3 went 13.0. The DCT ran 12.7, what can you conclude from that?

I have done the DCT vs. manual M3 thing myself, the DCT wins every time in practice. Best way to find out is go do it yourself

 

Well... depends what you consider significant. I believe there is room to hit 400 wheel NA which would be a 50 wheel gain. That is also 100 wheel HP per liter and anything more will be tough, NA on stock internals.

 

Sweet man!

Good work

 

M3 or 335, either way you can't go wrong.

Both offer impressive performance and comfort for daily driving.

Awesome times, especially for $1200.

 

If you notice, the difference starts above 120mph, and its due to gearing. By 150mph, 2 seconds is very significant. The ETs you are quoting, corrected for DA or not, are at speeds below 120mph.

I have no doubt regarding the consistency of the DCT, but I'm guessing you didn't practice at triple digits?

I can see a 50whp gain from a 6 liter motor (6.1 Hemi and 6.3 MB), but for a street-legal 4.0L production motor already at 100hp per liter, I'm going to say it's impossible with intake/exhaust/tune.

 

I'm use to hearing about what is impossible with my car from people who don't have hands on experience. The S85 gains more than 50 wheel with bolt on's. The S65 is based on it and I'm probably already there. I'll be sure to give you the numbers soon.

Oh, I think when I am testing my vehicle vs. others in practice triple digits are a very easy level to get to. The DCT is not only consistent but geared closer, above 120 it has too large of a lead by that point for the manual to start to close it. If you are familiar with shorter gearing there is a point where the torque at the axle advantage is negated by time spent in gear. Basically, they would just maintain equal distance at that point due to power being equal.

 

I'm looking forward to seeing the numbers, but it sure isn't 50 Rwhp.

Taking launch/mutiple shifts/driver out of the equations, try a roll-on from 100+ against a 6M. You may be disappointed...

 

These threads will never end. I find them funny and entertaining, please argue more about your cars. I am going to go take another pound of air out of my rear tires so I can get a better launch when going to the grocery store.

 

BMW has really set the stage for these arguments. They take a car that's already popular, throw in a sweet engine that becomes a monster with little money and then release their premium model with a +15K higher price tag......

I don't own either but I think one of the things that really is disappointing about the new M3 is its relative lack of torque. Especially when compared to what these tuned turbo BMW's are making.

It makes for nice bench racing anyways. Obviously, the buyers of the flagship car are going to defend their purchase to the death. All I know is BMW was very smart because they're bound to sell a TON of twin turbos...far more than M3's. They know this and they found a perfect formula to move more volume to the tuner crowd.

 

Yes, but at what price?

 

Then from 150-172 the IS-F pulls away in 8th gear with it's gimmicky fake exhaust tips working as a diffuser creating downforce

 

M cars > 335i.
