Super charge your chimaera how many have & what do you think

[richarddorman]

I am looking at this path or change the car for a tamora. Would like to no what you think of the car after super charging my car is a 97 450 chimaera .

[thenick]

Just about to slap a kit on mine, I'll let you know how it goes but from what I've heard so far, it should be rather quicker than a Tamora! Don't forget you'll want to look at brakes and suspension as well though or you might not stop

[richarddorman]

The suspension bit is already under way.Thanks please do keep me informed are you going to fit this your self ok get someone to if this look forward to hearing the out come . I would really love to hear from poeple with a 450 and what difference they have found

'Blues' is your man for info on the 450 on PH

I will be fitting the kit myself, yes and it will be to a 450. I'm just waiting for the kit to arrive, and need some modification doing to my ACT manifolds in order for it to fit. Should be on in the next week or two I would think though! With the Emerald system, I should be looking for as much or more power than the 5L supercharged apparently!

Is your super charger kit coming from sc power

Why? You'll still be doing the same speeds as before (and even later 400 models had 500 brakes as standard anyway), it's just that you'll get to those speeds quicker with a blower than without.

All non-abs brakes are ultimately only as good as the adhesion between tyre and road - and you can get to the limits of that with any set of brakes on a car - improving your brakes will (hopefully) give yourself better control before reaching the skid point so getting the shortest possible stop, but I don't think you will otherwise actually alter the ultimate stopping distance.

To really be able to improve braking on a TVR, you need to go to ABS

admission time: I've put dimpled/slotted EBC discs and green stuff pads on my Chim (but replaced old Bilsteins with new) and once the taxman has taken his dues, if there's any left, it'll be a blower for me too.

Things will happening a whole lot quicker, I drove a stock 5 litre chimaera the other week and was so surprised how crap it was (yes I know the later cars had the same brakes/shocks but...fade city) would not dream of any power mods without upgrading the basics first

If your only using your TVR on the road then the std calipers and shocks are will be up to the power increase. If you are going to track it then upgrade the shocks and pads and if you like to give the brakes some real stick then get bigger disks and four pot calipers.

I used the std calipers on mine for quite a few track days. I used Mintex then EBC yellows pads and the brakes were fine. I never experienced any fade but after a nice chap took this photo at Brands i decided to nick the big brakes off the Griff to do Spa and the Ring.

ok, but doing a 100mph in my non-blown 400 is exactly the same as doing the 100mph in a blown 500 so the braking requirements are the same (maybe less in the 400 as it's lighter).

Even if you are saying going blown, shall we say, raises the average driving speed, the braking requirements still don't change - all a blower does is get you up to your desired speed more quickly - unless of course you mean that as the top speed is now a lot higher you better brakes to slow you down from those dizzy heights.

Or are the factory fitted brakes not good enough for normal, even sprited driving, blown or not?

Finally some one else with my viewpoint on brakes However, what bigger brake discs and 2/4/6 pot calipers do is dicipate the heat quicker, which is the achiles heal of any braking system.
With the SC you will be entering all the braking zones on track 20% quicker than you did before, which will build up more heat pushing the limits of the stock kit to the point of brake fade/air locking(failure) much sooner.
It is for this reason that uprating your brakes would be a good idea if you track your car, you are very unlikely to have this issue for normal road use, if your brakes are in good order.



Erh...Dave, have you left any of Colin's Griff for him to get ready for the SpaRing trip?

[thenick]

To be honest, since upgrading my brakes I don't know I lived with them before. I hadn't driven my Nissan in quite a while and always considered it to have sharper brakes than the Chim as it has fast road pads all around and doesn't weigh much. After driving the Chim for a month with Wilwoods on though, I took the Nissan out and was shocked at how little the brakes appeared to do in comparrison.

Since noticing this, I would really recommend upgrading the brakes on even a standard car as it gives you such a lot of confidence in the cars capabilities. I know it doesn't change the limits of the tyre but on the same wheels, Wilwoods really try and pull your face off in a way that the originals never dreamed of! Upgrading the brakes and shocks really have been the best mods I've done to the car, it completely changes the way the car behaves. To back up my view, an instructor commented on the car at Cadwell Park a couple of weeks ago, saying it was one of the best set up TVRs he had ever driven - praise indeed

[poorpeet]

I went from std 240mm to 283mm with Cossie calipers. All I know is that the brakes feel much better. The initial bite is better, pedal pressures are less, they are much easier to modulate, ultimate power is much better but without feeling grabby & I have not had any locking up issues. Also it seems to feel more planted under braking. Not sure why as you'd think the back end would feel lighter under heavy braking & move around a bit.
My old brakes were in excellent condition but the new set up is a huge improvement.
IMHO

Why do all these kind of threads turn into a discussion on brakes? Come on fellas, let's get back on to supercharges

Are we talking about the TVR Power blower and what's involved in fitting one yourself?

[thenick]

Good call... appologies all! Chargers and bhp it is... I've been looking over the installation manual and tbh it doesn't look that bad at all - much easier than the Emerald and SC-Power reckon its around a 20 hour install all in with the intercooler and everything. The only bit I'm not looking forward to is taking off the offside rocker cover to put in a splash protector. I know that bit is always a ballache!

[Stevie Mojo]

Thanks Nick, doesn't sound too bad. What does the DIY kit cost if you don't mind me asking?

[charlie 777]

hi i have a supercharger fitted to my 4.0l and it makes such a difference mid range performance is brill especially for a 4.0l (installed by tvr power great job)ps i did upgrade brakes to willwoods much more stopping power and inspires more confidence.pound per bhp i think it is a great invetment

It was a shame I didnt make the Growl, I think I would have bought everything in that jumble they had.

I'd also like to know this please, and what 'extra' is required aswell as the kit.
Does, say £500, sound like a reasonable estimate for mapping? Assuming nothing is wrong with the car.

Also, people say to make sure the engine is 'tip top' before fitting the kit, how do you check this out? Compression test and general road driving test, or further checks/tests

Thanks
