Cerbera 5.5litre Stroker Kit Out!!!!
Discussion
I remember quite a few were interested, and now the 5.5litre stroker kits are in stock!
So if its about time you gave your cerbie a power-hike and a fresh clean rebuild, then crafts new stroker kits are the dogs danglies
In stock and turnaround time of 3 weeks, and you get a full warranty with the job
I said a while back I'll do everything I can for the cerbie community, so here you go!
And an awesome price too!
Time to treat the good old-goat some muscle and TLC

If they did all eight cylinders, you could have 6.5 litres 
agree that crank looks a little short on cylinders Hmm very nice to have but so much to consider here. Whether it would stop the free revving nature of the engine. What you'd need to do to a head that already doesn't breathe very well. Although I wonder if this'd give the car the V8 sound its always needed?
I think 550bhp is very optimistic, how did you come upon that figure?

well all things being equal just a straight 22% extra hp from teh cc will give over 500bhp on a red rose spec engine .. we know they have a gifted head guy who's bound to be able to find the best flow from the heads..
also don't forget that adding stroke increases torque over and above the bare capacity increase as the leverage on the crankpins is greater, and hp is just torque actions and how many times you produce it (ie revs) so if you can make it rev like a std car or better then the bhp figure rockets ..
so it's very possible that 550bhp is on the cards imo
the other great thing is I spoke to Dave on the phone yeterday and he's a lovely bloke

I'm a bit confused as to the potential output, as
Whatever though, it seems that TVRCRaft are leading the way in TVR engine developments.
SXS in another thread said:which seems a small increase for a supercharger if 550 is possible without? Saying that 600 is a big number and could be achieved using less revs without over stressing components?
Currently they are building the 550hp supercharged tuscan, and a 600bhp supercharged cerbera 5.5.

Surely this is how the capacity increase gives you extra power i.e. it is the only direct effect, it isn't "over and above".
Perhaps a difference between a "bored" and a "stroked" engine ?

Typhon is off . . . new Cerb is just drawings . . . Do you mean 'they' as in 3rd party?
JESUS CHRIST - how much? - that it is a billet crank? - has to be 3k at least for that alone? Piston 150 - 200 each and rods 200+ each Eeek - does it need top hatting though like Bosscerbs? An yes has it benn run up yet?
ASH - does this mean yours is 5.5 not 6.0 then?

And that's setting aside the necessary drive train upgrades too ....

Surely that power would be made if it could rev and still fill the cylinders to the same efficiency as a 4.5 which would be very hard . Just fitting the long stroke crank would make little difference to the horsepower though there should be a big jump in torque .

Adding a litre displacement would make a difference in hp. Maybe it wouldn't jump to 7.5k that fast but it will get there . . . and djees do you need way more than just a crankshaft. :said Dink who used to work Kreidlers at 15: Gassing Station | Cerbera | Top of Page | What's New | My Stuff
