Regardless of engine, or tune or power adder.

As I understand it (in order):

  • Craigs Cerbera 4.7 NOS'd at 520bhp
  • Brummies yank powered Cerbera at nearly 500bhp
  • Nick Chandlers Red Rose Cerbera 4.5 'tuned by TCS' to 441bhp
  • Daggarts Cerbera Red Rose 'Austec Racing Heads' at 440bhp
Have I missed any? Just curious, these are the owners who have come forward with dyno charts to prove their results thus far.

Quiet a few cars north of 400 now, but still hard to achieve yes.

Heard another rebuild left Austec this week sucking through bog standard 4.2 top end gear and knocking out 404 with lots of potential, at least 430, poss 440 or so confused.

404bhp here!

TVR Power said the Boss dynoed 440Bhp there.

Thats interesting I know Craigs NoS Cerb had about 385 at the wheels there without NoS

Unforunately not quite. Cyclone experimented with some radical induction to achieve 425bhp but in "road" trim it's pushing 407bhp as checked by Joo a couple of weeks ago.

I've been out in it tonight and regardless of the actual figures, it's impressively fast. I took my best friend for a spin, his first in this car, and he was blown away. I love it.

Some bloke reckoned he'd get 1000 bhp a while back. Believe it when I see it. biggrin

Pretty impressive. Wonder if Joolz can get more from it ? What about the torque....! I prefer torque talk to BHP (bit like length v width!)

Nope torque has no place being discussed regarding a Cerb.

Next you'll be comparing a Cerb to a yank tank. smile

I think a lot of the more radical induction mods wirlwind or pulse plates are sacrificing torque for BHP at the higher rev ranges, and thats just how it should be with this car.

Any of you with impressive torque figures should be looking to mod to sacrifice to get high end BHP.

The character of the Cerb is such that to mod it should be trying to make it more like a racing car not less. The challenge for a racing car driver should be that his feet are always on the go to keep the race car within a narrow power band, and sound like a flat plane crank should. He should get out of the Cerb tired and exhausted.

It shouldn't be a fourth gear roll on at 60, as the medallion chested, silk scarf wearing mediterranean turns to his bronzed girlfriend in the passenger seat and tells her to feel the width.

If you want an armchair and the ability to talk torque figures get a jag!!

Isn't torque directly related to BHP, therefore if Torque increases then so will bhp?

Short Induction is not necessarily reducing Torque, in most instances where mapped correctly it increases torque and pushes the peak point higher up the range, which in turn increases power through the range and higher up.

Torque is very, very important, if not then all the Cerb would be good for is all out acceleration from a standing start and no flexibility once rolling.

Well, thats rather getting into a discussion of torque Vs BHP definitions, and I have to admit I agree with you they are pretty vague.

I assume BHP is a quoted high revs power figure and torque is a mid range power figure. Both attempt to describe a power curve along the whole of the rev range, and neither describes it better than a dyno graph. If the dyno graph looks like a triangle then its high bhp and low torque, and if it looks like a hump back whale then its high torque and low bhp. But I agree with you as bhp and torque are only two names for the same thing albeit at conventionally different rev ranges

So if we swtich back to dyno graphs for a min. Tuned induction of course is only tuned for a certain rpm. You can choose when choosing your induction where along your graph you want to boost power. However it either has no effect or a negative effect at other revs.

The Cerb suffers from poor fuel mapping and I think you've intimated quite rightly that improving that defect, seems to improve the curve all the way along. But not sure getting rid of an obvious defect is the same as having to take the rough with the smooth as far as tuning goes.

However the character of the car is also displayed by the dyno graph. The Cerb should (in my opinion be a racecar not a GT). A progressive line reaching a tall peak at 6K would be ideal to suit the car.
A big central hump running out of steam at 5K would be a yank tank. This is regardless of what the actual figures are.

If you asked me which one would win the race thats another question. High torque suits a lazy driver. But more than that. A decent british racing car has always been about low torque and high power beating much higher capacity high torque lazy engined cars from across the pond.

thanks for that - I think you've captured exactly one of the main reasons im not feeling the cerb as a fast car, I'm used to driving torquey low end power stuff, and not driving keeping the revs above 5k. I always feel like I'm damaging/thrashing the engine when i run it for more than a second or two at 5k plus

Last time on the rollers my wee baby was

443bhp & 371lb (no nos)@ Fly. (still never fitted injectors or new throttles!)
679bhp & 512lb (NOS) @ fly. But it was not 100% happy and I need to resolve some minor fueling issues. And she is undrivable on the roads using this much NOS. But TBH she doesn't really need it.

Anyhoo keep your eyes peeled in about 6 months time for the new improved version kicking out a wee bit more and slighly different body. (only cause I need wider wheels to lay it down hehe)

Honestly I think we could learn a lot from you, if you'd just give us all a step by step of what you did to your standard car. Nos is simply a willy extension for a superb car with a big enough willy already smile

How about you let us know some of your secrets wink. The ones where you increase the airflow into the cerb engine without messing about with the fueling.
