Should I buy a c43?
awesome work as always from you!




user "speedybenz" had a 55 swapped C43 and he somehow custom fabricated velocity stacks inside the throttle body, and he said it made the biggest improvement over all the mods he had (and he had done them all).
according to him, his car was beating M156 C63 AMG's in the quarter mile, no supercharger required!

But I believe speedybenz added these to the intake manifold. Can't see any velocity stacks fitting in the small throttle body. I could be wrong though....

and cut off two throttles to adapt for the V8... 
Just kidding, but I imagine if you have deep pockets the sky is the limit

i heard many guys reached (395hp), don't know how..!?!,,
with my previous "C43/55", i reached (375hp) with MAX overload performance parts..?!?!?!?!

i believe 90% of gains is in intake/exhaust.
share with us your special upgrades
Can one of you guys make sense of what speedybenz wrote long ago? I found a thread he started which he added the velocity stacks to the inside of the intake manifold. Sad that the pics expired, would love to have seen it. But below he said this and I would like to do this to my second intake mod.
Here's what he wrote:
"I found through trial and error and back to back testing that disabling the two stage runners and removing the bottom, long section of the manifold runners opened up the plenum area greatly and seemed to almost eliminate most of the lost low end torque."
And thanks for wanting to read Jeff's post.

I know you know your stuff man but thats some major mods. If you are not doing 400 at the crank with those something is wrong :/
Even with 5hp per mod thats still like 30 extra hp but im sure some of those will give you extra




i can tell with big smile that i gain more than (400hp),,
but love to be in FACT of Real HP than something i desired, or wish to reach..

what happened? someone offered you more money than you can refuse? lol
