The same could be said if you put bigger turbos on the 5.5.
Stage 1 Weistec blower on a 6.3 vs what we have seen the 5.5 put down with a tune only and I believe the 5.5TT has it hands down. Never mind in a lighter platform like the C63.
Plus as we know dyno numbers mean zip. What can it do on the track is more important. You can make all the power you want, if you cant use it its worthless.

FF. W212 E63 M156 non-pano 18" P2 ParkT NightV (gone but will be missed).
Yes, anyone can strap on a rocket, but the hardest thing is how to utilize all that energy and power. Like the good old Pirelli slogan, "Power is nothing without control."

M156 has almost a liter more displacement. It will make more power.
I think it's only fair to compare twin turbos to the larger 3 liter blower. Maybe compare the 2.3 L blower if it was a single turbo.
I'll meet any biturbo 63 at the track in the spring, we can put this to the test.

LOL. Kinda silly to say "Only Fair" when you are comparing two vastly different modded cars and weight differences.
What would be "Only Fair" would be to compare a C63 with a Weistec stage 1 blower with no exhaust work verse a tuned 5.5TT in a C63 with no exhaust work.
Looking at the data we already have a CLS63 (55TT) without exhaust work and only a tune would spank a C63 with a Weistec stage 1 blower without exhaust work and it weighs about 200 pounds more.
Maybe I am wrong... I am open to some examples if you wanna point some out.

Playing the numbers game is easy. Actually making it work is a different story.

We are all paper racing here.. But I think the peoria that build both of them would know.. As we know weistec also has ecu and other various upgrades for the m157 biturbo engine and they've clearly stated a couple times that the blown 6.3 is the faster car and they've said the head is a much better breather, bigger displacement, and the ability to rev higher and make the most of its power band. I believe what they say as They have no reason to push one over the other as they sell both but hopefully well see some head to head videos soon

Doesn't matter.... Either setup will overwhelm the tranny before max power could be attained. Why do you think the few big power project camps have been so quiet lately??

Thats true. I guess we will see with time.
Its all about how strong the bottom end is and how much it can take. If the 6.2l can take lots of boost it will make more power in the end. If the bottom end of the 5.5l is stronger (Thicker cylinder walls with smaller displacement ect..) it can take more boost and put it beyond the HP the 6.2l can make even with the bigger displacement.
Its all about limits. This is why Supra's are able to take 30+psi of boost on stock bottom ends. Try that with a 6.2l or a 7.0l LS7. Boooom.

Is this why Dads is no longer drag racing?
I wonder why no one has tried the Renntech tranny?
Would like to hear from Jcart or Ecampbell regarding their tranny's and how they are holding the power..

Propain yea I hear you brother .. Those supras have an iron block and with forged internals they can take silly amounts of boost .. The m156 and m157 both are aluminum and both would probably need upgraded internals to make all this crazy power so I think the extra displacement and higher rev ability gives it the lead for now but we shall see ! I was only quoting weistec as they have 2 horses in this race and that's what I've directly seen them say ..

Ive also heard rumors that the m157's with tunes pushing the boost up have had problems with fouled plugs and them dropping into the cylinders. Don't know how true it is .. Another thing the m157 has over us is direct injection which could help with higher boost levels and Pre ignition
