Warning sensible thread... cerbera SC500 what do you think?

[classic105]

I know, it is very sensible and not for the purist.

i'm totaly agree with their thought (cerbera without AJP or sp6 isn't really a cerbera...)....

BUT.... nevertheless, what do you think about a TVR cerbera with a TVR 500 supercharged engine/powertrain? (a chimaera SC500 engine)

It could be close in power, perhaps better in torque, very good sound TOO, very useable and maintenance wise could be less expensive.

But less free revving and could uppset the chassis weight balance a bit (don't now really the real life weight difference between the 2 engines fully dressed).

best regards

Yes seems someone already done it with an NA rv8 500 for a daily driver Cerbera.
Seems to be few mods to the chassis, but don't know more.

Hey !

You gotta do something during the Lockdown....

Go fot it !

(Oh, and while you're at it, I'll have that low-performance, 'block-of-alloy-filled-with-steel-inserts' off you )

Hi, i already done the complete body off rebuild of my Cerbera 4.5. Sandblasted châssis outriggers zinc and époxy powdercoating, all Wishbones, up rights and all nuts/bolts/washers during the lockdown.... Must do something.....

This. Or be original and get a Coyote or Voodoo..

The coyote engine would be a very good option but perhaps too wide and gravier than the rv8.
But don't know if the Cerbera hadn't been a mule for the New Griffith to test this engine?

Interesting question. I would ignore the haters and consider whether the end goal is worth the effort..
As for a Rover V8 in a Cerbera, I saw one for sale a few years ago.
.




Macded made good power from his 4.5 Turbo Rover engine.







likewise Hiltonig developed an amazing 5.4L supercharged Rover V8, both in Chimaeras.

Good luck

I admit it is an interesting point of view.

Many thanks for pictures.

The headers are not forward , perhaps it is possible and easier to use the forward headers of the chimaera.

Pretty impressive the BHP numbers but prefer the super charger route for less heat, better sound and lag free power.

I'm very impressed by the work done.
This Cerbera must me astonishingly quick.
They are already impressive standard, but mods like this one woohoooo

Yup, they cut the front of the chassis around a bit and it was a tight fit

Thanks for sharing pictures, major châssis mods in this case, but the quad cam fit in width.
Another quad cam have been fitted, IT is a Maserati 4.7 that sound fantastic. I know very well this engine and it is epic, free revving and troublé free when the cam variators have been upgrade, so in a 2400 pounds tvr..... Graal....but don't know the weight for châssis balance.

Off topic a bit but the centrifugal chargers are more laggy than a turbo at low revs because instead of just having to wait for the exhaust gases to spool the turbo you have to wait for the engine revs to increase to spool the supercharger ... at low revs a centrifugal charger makes next to no boost.

Not off topic at all, it is very interesting and welcome.
The only turbocharged very powerfull car that I know well are Maserati 3200gt and Ferrari F40.... So for the lag.....
I'm found of the F40 for her "savageness" Or rawness, light weight, and assistance free, but don't liké so much the sponginess feel of 3200gt not heped for sûre by his first in Maserati history drive by wire. But like much the 4200/qp NA.
I think the Turbo could be more powerfull, but the feeling that I had expérienced let me think that I would like much the supercharger, for the sound unmuted too.
Ironicaly, I have never try powerfull super charger engine, so I trust you, and perhaps à well turbo setup with good mapping could make me reverse in my opinion......
Do you Think that the Rv8 500 turboed could be better than à supercharged one (Sc500) ? With no lag?
