Options to get to 750 rwhp/rwtq

[Fundguy1]

Just trying to do my research. It seems to get in this neighborhood, stacked dcm and jb4 tunes, intake, catless downpipes, exhaust, and dct clutches and I'm close. Correct?

Also, do the different exhausts matter for power or do they all make the same but vary in price, sound, and weight mostly. Same with intakes and downpipes. Thx.

To get to 750 with piggy you will need meth or a flash on top of piggy.

To get above 700s whp/wtq, I'd say catless DPs, upgrade MAP sensors, custom flash tune, SSP clutches are the minimum. I also like the RK Autowerks intakes because they're proven to make power above 5k rpm.

There are other ways to get to >700s involving JB4, but that's not the route I'm taking.

Exhausts post catless DP's are for making drone and nothing to do with power unless pushing 1000BHP+, money spent else where is a better bet.

You have three choices realy

JB4+BMC+ Meth - removeable option
DME Tune - you have to remove the DME's send them off by post if the tuner isn't local and then they have to open the glued cases or drill holes in the cases so there are signs of tamper
DME Tune stacked with JB4 for extra features and flexablity (selectable boost per gear etc)

You will need a SSP clutch come what may...

Do your research, there are some good tuners on here.

This is what i was looking for. So exhaust won't add power on this platform?

Good to hear about the autowerks. Any others?

Not married at all to JB4 and I don't mind DME tampering

MSR. I honestly don't know which intakes make the most power, and could care less. The sound you get from the MSR is worth it's weight in gold.

SSP Spec-R is a must. Your clutches are on borrowed time at 650rwtq+. Mine were toast at 39k miles. Now the car is a monster.

Also recommend chatting with Mike Benvo at BPM. He has a very highly regarded reputation and has tuned many, many of our cars. Mike Benvo

We don't like to breach ~700hp on the stock turbos.

[Padfan9]

Do you guys think our motors / clutches are safe to run 630-640whp as long as we don't track and drive smart? What's the real risk ? Let's say intake, exhaust and flash tune only ?

[allmotor_2000]

Engine will be fine with flash+intake+exhaust... clutch maybe not depending in the torque targets

Gotcha. 700 would be ok. Stocks burn out over 700?

I have heard there are more then a few blown S63T engines.
Rod bearings and such.
Good question to put out there because we all know you can push the performance so far until something stock fails.
Anything over 700 WHP is just waiting for something to fail in my opinion.
Might not be right away but long term wise

[ur20v]

Clutch is more of a problem on the street than the track, on the street you can plant the throttle in a high gear at low rpm (less thn 4000rpm) and all the torque from 1800rpm up can slip the clutch, high revs and track use and you will probably be ok at higher levels.

[Fundguy1]

So 700hp is pretty bulletproof and 750+ more sketchy. Thx

There are tons of blown s63tu's but for various reasons. 700whp is fine as long as its tuned correctly. I mean it won't last 100K miles but if you want that, stay stock.

[MissionPerformance]

The highest we have got stock turbo M5 was 767whp/787trq BUT that set the stock turbos way out of their efficiency range to the point that they were choking on a 50-300km/h pull. The sweet spot for stock turbos on these engines is about 35lb/min of air per turbo, and that roughly translates to 750crank HP (~650hp). At those power levels, you should expect the turbos to last some time and not have sleeve or shaft failures.

could i just upgrade the rods and or pistons to solve the weak engine issue if wanting to head towards 1000 bhp, or do you have to totally rebuild?

Replacing rods and pistons is rebuilding... as motor needs to come out and taken apart.

everyone keeps saying there are blown engines all over and we haven't hAd 1 thread, tear down pics, or cause of failure that i know of.

hey guys thanks for the info but i have some questions, just about evert stage 1 tune out there make 650whp, everything else goes up from there. Are you saying that many cars are running around outside the efficiency range of the turbos??

[josec70]

Doubt you'll get much 411 on a public forum regarding blown engines. Tunes, warranty issues etc.

Just my .02

I'm sure 90% of our driving is not at WOT, where running higher than 650whp for extended time will grenade the turbos too soon. That's why many can run stage 2 numbers because they're not on it all of the time. I'm aiming for 700s myself this summer on stock turbos, but I'm not too worried because I know MissionPerformance can do a good tune, and I know my driving habits.

[Fundguy1]

Ok so if the turbos grenade im not so upset. I'm worried about the internals. What kind of power level can the internals take for a couple hundred k miles without doing a built motor?
