Rofl! I love how you call it the "wifes" car

Quite a grocery getter you got there 🙂

Check your man card at the door, if you can find it at the bottom of your wifes purse😀 J/K

Not too sure, will have to dyno when it gets back.

After all said and done, it should be over 700 at the crank. It's a pretty conservative kit at just 6 psi. It's designed for reliability and usability, with a torque curve that mirrors the stock one. OE compression ratio is 12.0:1, so going much over 6psi this isn't all that worthwhile on 91 octane.

700 BMW HP... lets see if I do a conversion here that equals about 550 porsche HP and 650 Aston Martin HP. 😛

Looking for that top gear episode where they put the M5 vs the 911 and the A.M. ...

Sweet ride OP, be carfull though, with that much HP...heh well you know.

Did you remember to strengthen all of the other parts of the car? There are lots of videos on the net of cars with enormous turbochargers and it blows the car apart. Transmission all over the road :biggrin:

Wow, 130 mph at streets. That thing would be downright scary on the big track... 700 hp and 2 tons of German auto screaming down that 1/2 mile straight.

Yeah, I was surprised at the speeds it could get to. The M5 is a monster above 120mph or so. It accelerates really hard at high speeds. At just 560-570hp, above 140mph, it's accelerating harder than a 600hp 996 TT. Pretty crazy considering how much smaller the 996TT's frontal area is (and of course, the power to weight ratio difference).

A 400hp M12 Noble gets to about 140mph on the straight, counterclockwise, DOT tires. To be fair, it's carrying much more speed coming off the kink though.

:/ Are you sure.... oh wait are you talking about feeling like it accelerating faster or it actually is?

Because heavier car, less HP, and less aerodynamics, is somehow faster, I just have a hard time wrapping my head around that.

The M5 is probably not geared for high speeds; consider its 155mph limit.

If the M5 were geared for top speed of 160mph (redline-limited vs power-limited), I would certainly expect that it slaughter the 996 Turbo which is geared for a top speed of ~198 mph.

My 6-speed 996TT with Ultimate Motorwerks K16/K26 Stage II turbos, custom airbox w/BMC filter, EVOMS tubular manifold, 3" RPi exhaust, RPi high performance bar & plate intercoolers, Sachs uprated clutch, lightweight aluminum flywheel, ESS software tune, C's shifter, H&R coilover suspension, HRE forged wheels, carbon hood, 10-lb battery, CF GT3 seats, Techart wing:

Actually is.

Tallerize the final gear ratio ftw

Actually, the M5 is geared for 215mph or so at redline in 7th. Stock, the vehicle is aero limited to about 202mph or so, despite the optimistic speedo.

The 165mph limit is a software limit (supposed to be 155mph, but the OE software cuts in late). Pretty easy to remove.

The M5 is capable of ~200mph with stock gearing. The 155 limit is electronic, not bound by revs. However, I would be surprised if Mr Apex hasn't had the limit removed, which is a very simple job.

EDIT: beaten to it.
