Are you finally turning to the dark side then Peter? Is it a regular on here?

Hasn't that car been on this forum before, it looks familiar?
Thread from last year on the same engine...https://www.pistonheads.com/gassing/topic.asp?t=16...
That would be really unlucky.
The trouble with turbo engines is the power comes in very quickly with a bang. You need to constantly consider this. Accelerating in the dry could be challenging but in the wet, it could be downright dangerous.
My NA torque is extremely constant, (370 from 2K rising to just 430) and yet I have had wheelspin in fourth at 85 miles an hour on the motorway on a lightly wet surface.

Hello.
I think I may be able to shed some light on the engine that you are discussing.
I sold my Chimaera last year to a very nice gentleman from Morecambe. He had a blue Chimaera before which unfortunately he spun on the motorway writing the car off. The engine is out of his car and he had the turbo conversion carried out whilst the car was in his ownership.
I think he spent a fortune on the car and it was his pride and joy. I don't think he has any plans to turbocharge my old car though....
Regards Chris.

It is absolutely perfect in every way.
A bit like the three bears porridge, not too slow, not too fast but just right and perfect for my skill level, ( well I haven’t crashed yet!).
You should try 385/430 bhp/torques!
Does make my 360/354 look a bit tame A bit like the three bears porridge, not too slow, not too fast but just right and perfect for my skill level, ( well I haven’t crashed yet!).

Apart from capacity i think our engines are in a similar state of tune.... I wondered for a while how it is that you have so much more torque, I'm thinking it must be the different cam

For me this is where the Rotrex kit scores, if you look at the power & torque delivery a supercharger demonstrates on a dyno graph it would seem the effect is to make a smaller engine behave like a bigger naturally aspirated one, the power delivery appears to be served up in a very progressive way making the car extremely predictable in how it responds to throttle inputs.The trouble with turbo engines is the power comes in very quickly with a bang.

If I chose the turbo path I'd worry I might just have that constant little bit of concern in the back of my mind the car could instantly break traction at a wrongly timed twitch of my big toe on a damp day, I could also see this taking some pleasure out of my TVR driving experience.
One of the most important and little discussed ways to deliver true driving pleasure is to ensure the driver feels complete confidence in what the car will do, both in it's handling and it's power delivery. The way I see it's all about control, and control is defined by how the car responds to inputs a driver applies to the vehicles controls. When you drive a car that gives you this confidence you naturally start to bond with it and explore its true potential, if the car doesn't give you this confidence you can end up with somewhat of a knife edge feeling especially when your pressing on, in turn this stops you from relaxing into the driving experience and will interfere with the pleasure we all seek from driving.

I had a conversation with my local TVR specialist last summer about turbos and he said Eann had had two blue Chimaeras, the second of which had only recently been written off. Could be the second one?
If I'm reading this correctly and Eann has indeed binned his second blue turbo Chimaera, then the one discussed in this post makes three down, that's a big percentage of the turbo population right there. Looking at the published dyno graphs from these turbo cars it's not hard to see what might be going on here, obviously we are all driving gods and it'll never happen to us but if we add a dose of realism for a minute and take another look at how these turbo cars pile on torque in such a narrow window.... one might hope we all are at least left with some food for thought Given our crowded roads and the fact even a little normally aspirated 4.0 litre can propel you down a windy country road faster than it can handle the bends, surely brakes and handling should take priority over adding huge power? Even on the track Matt Smith in his normally aspirated 4.0 Chimaera has proved handling and driver skill can put him ahead of many of his much more powerful competitors.
There's no arguing peak HP and torque numbers deliver fantastic bragging rights... but what they dont tell you is the really important bit seldom discussed, IE how and where that power is made, only a dyno graph can show you that but even then because engine behavior is all about what the driver feels only driving the car will reveal if a certain shape of power delivery stimulates your personal pleasure gland.
I'm not down on turbos, they definitely have their place, everyone's tastes are different and what you think you'll like on paper may actually be very different to what you find you really like when you actually come to drive a car. This happened to me a while back when I drove a friends VX220 Turbo that had been lightly wound up to 250hp/torques. Now...I don't like mid engined cars and I was even more skeptical of turbo power delivery, but here's the thing..... that VX220 Turbo was an absolute hoot to drive and I loved it so that's me told.
However, on a V8 TVR that already has 240hp & 250 ft/lbs I can't help feeling the linear power delivery of an engine driven centrifugal compressor may better suit my engine behavior tastes better (and be safer) than fitting a turbo?
I've always found RV8's with turbo's to be quite 'normal' to drive. They're not peaky like a small 4 pot engine and the power come's in progressively as it builds up. There's certainly a big rush when you want that to happen but never in the wet. That would be plain stupid. In the damp I always treated my car with respect and was light on the throttle especially on sweeping bends.
