Ok sir... better to stop it here... didn't want to hurt your feeling BTW

I guess you need to read my original quote (post #15). Your friend quoted on this one. I clearly was talking about stock components and not upgrade ones:

Let me tell you something buddy, if this car has an engine generates 900+HP then all other components (DCT, Diff, axle, cooling, ...) will be blown up shortly since non of them are design or rated for this type of power...

Im close to 700whp and not bhp (no problems at all)
Besides who drives stock car nowadays these cars are meant to be driven
My manual m5 wnt needs clutches at 800whp. I like to use whp no bhp so they can figure crank hp which is pointless to me when they say bhp and not what it puts on the ground.

These snails are on the car so another 800whp in the East Coast

Ok buddy thanks
Have a great Sunday

are these cars putting down over 800hp dct or manual?

NOt Hp, or BHP,

its putting down over 800WHP 800+wtrq

and yes both dot and manual

Even if there are drive train issues, the cost of putting higher performance parts in is minimal and something we can do when we cross that bridge. Axels are $2100 and drive shaft cant be much more. For the amount of money invested in these cars, these upgrades are a dime in the bucket...Have a good day...No hard feelings..

I honestly have no idea how those guys didn't understand what you were saying.

LOL. 800whp = 900+bhp.

No it'd didn't blow up. No it won't blow up.
Yes it's upgraded parts.

My thread went to Neverland lol.

He did have a V10, has F10 now. Seen it in person.

LOL... sorry for but I had some points since I believe the F10 M5, a well engineered car, has been design by one of the most expert engineering team over the world working for one of the best German automaker
The main factor of a well engineered system is to have components at the same or close level (of performance) and any change to any part of that system will affect the other parts and must be considered during the design following the most important concept of that system...

Sorry - but who has run 305/30/20 Michelin PSS on the stock 10" rear 343Ms and had a problem? And if so, what problem?

let me ask you this, in your opinion.. what is the safest power level for a completely STOCK m5? not upgrading clutch etc..

I have driven with > 700whp for the past 10K miles and I drive HARD all the time. It is in the 780whp range for daily driving the past 3-4K miles... and 825whp+ at the track. All of this with 800 ft-lbs torque AT THE WHEELS.

So Middly is correct, the car is holding it. I was sort of lucky my axles did not break when launching on MT's (1.60 60-foot)... but planning on upgrading the axles anyways.

Now.. could something break. Sure... guess we will find out. The stock M5 is probably holding 15-16psi boost. An additional 10psi when tuned properly is easily 200-250whp.

I have heard of many switching to 305 and heard of Zero complain about them other that without changing 265 to 275 on front it changes character of car around corners.

620whp 620wtq with stock everything + Tune

those are solid numbers. So what we're getting at here is when pushing past the 800 mark, things need to start getting upgraded.

[cjrdriven]

315 R888s are really making a difference with WOT 40 hits.

Thanks - so many people freaking out that 305s won't work on the stock 10" 343M.

[cjrdriven]

For the record, I am loving the traction of the 315s. On warm day or on concrete lets the car take off like a rocket at WOT.

Many turbo cars are over engineered to handle the substantial torque added by the turbos. A good number of turbo cars dating back to the TT Jap cars of the 90s were engineered to handle twice the amounts of hp out of the box if modded correctly .... This is not something new. The new M5 is over-engineered, which is fine with me .

[m5sparky]

thats pretty good for stock internals. the dyno also is probably dynojet so it reads higher than a mustang dyno , but still incredible gains running on stock motor . im limited to around 600 wtq on the mustange dyno but hp wise the motor can handle 800 or so stock on the gtr, its the torque that kills the components hp not so much. also racing on drag radials is brutal on drivetrain, i found out after two visits to the drag strip that i needed a new built transmision to put up with the 624 mustang toque i was putting out or 730 dynojet wtq which is slightly higher than my hp numbers. sometimes doing a stage one turbo is good move because you could add hp numbers but bring the torque down to safer levels something i should be doing next lol. m5 is the family car so im not going hard core mods on it

[IANNUZZI]

Torque can be a killer.... The current stage 1 upgrades just exaggerate the torque early on as *only* the inlet side is modified, the exhaust side cant keep up at higher rpm. Once the exhaust side gets upgraded and we exploit the 7k rpm range these cars will be making over 800whp at 22-23psi....

Update: My different wheels and tires. Top is M6 wheel 20x10.5 with 295 PSS & Bottom is M5 wheel 20x10 with 315 R888. You can tell for the M5 that M6 wheels already stick out and a 315 would not work especially if you have a lowered car.

M6 343 has 15 mm offset less than M5 343 (+19 vs +34) so even the offset of 315 compare to 295 (10 mm each side) can't make it the same and M6 343 with 295 still stands out 5 mm more than M5 343 with 315

I am wondering if I will be ok with 305 on the M6 343 from fitment on M5.
