engine upgrade

[Krautchimaera]

Hello PH's your opinion wanted.
I have a 400 97 chimaera which I love, but driving the car for some time, I feel I could do with more low down pull. the car has a Tornado chip, dizzy amp and fuel pressure regulator and is running very sweet.
But still I am a bit disappointed by the low down pull. above 2500 the engine starts to pull strongly coming on the cam at about 4500. the engine feels quite cammy that is the best way to describe. will fitting an MC1 cam together with porting the heads and inlet side give me the desired effect? or should I go straight to a 4.6. If so there are two places known to me where to get them from, V8D and RPI. any comments on them?

Please talk to Rob/Ray at V8D Bernd, RPi might sell you an ignition amplifier .

And you deserve some good fortune

From what you describe sounds like it's quiet a nice state of tune .. the easiest was is to increase the CC..

4.6 or even a 5.0 - several some up in the TVR Spares..

5.0 in a high good state of tune at the moment .. just bolt it in. Job done.

traditionally tuning an engine as youre describing will improve the hp at the points from which it was previously being restricted .. this means more top end and little gain at the bottom. Your best action is to fit a bigger engine, or buy a car with one already fitted.

So it really is a 4.5 out of a fire engine then?

thanks for your offers,
but from my writeoff chim, I still have all the old 400 engine plus hardware, inlet manifold, plenum, AFM, good condition exhaust manifolds etc. As I am a bit skinned at the moment (aren't we all with todays prices !) I would prefer to upgrade the old one, or buy just a short engine.
has anybody fitted an MC1 to their 400 cars and what does the engine feel like compared to a standard TVR cam?

ebay both of them as lumps & buy Clives 500! Cam + followers + timing gear +gaskets, oil, water, time... is going to cost enough at the end of the day. You should accrue enough from selling 2 TVR 400's to pay for the 'upgrade'. There is not a lot to do to Clives engine/ecu/etc to make it one of the very best! Just ask Clive about the few mods that were left in the pipeline, and if you need to haggle - just make sure he paints it a different colour .

I have a 400 with an mc1 and v8d stage 3 heads and 72 mm plenum with worked inlets and trumpets the result was 260 bhp and 243lbft of torque yes it is a great improvement but i now want more so am looking at a bigger bottom end, i think the costs for the upgrade were quite high so my advise is to get a 5ltr and when you get bored then do the top end work or slap an sc on it.

it's all over now baby blue... I just had a letter from the German tax people today telling me that they believe I had not payed enough already. So I think that was it with my upgrade for now. We really live in a bloody rip-off country over here, with a system which punishes you when you work hard and gives you everything for free when you do nothing!! I am really fed up now!!!

You really need to tell them you belong to the Church of England, they don't want your money then for some reason?

Hello Dave, please believe me, there are so many other things I want to tell them !!!!
Problem is that fines are so expensive that my upgrade will never happen in the near future if I let them know my opinion.

kind regards
