Engine Mounts

[motul1974]

Hi, has anyone got direct experience in upgrading these, or is it likely to be another 'kings Robe' of mods??? Lol

My engine mounts were getting saggy such that the manifolds were almost touching the chassis rails.

The ones fitted for me were said to be 'uprated for speed 6 and V8 engines.' At £35 each, it didn't seem excessive. They are cheaper at TVR parts but that's before shipping.

Ok cheers. Current ones are fine....just whilst their out I thought I'd look into replacements if anyone had positive experiences with upgrades.

If they are in good order just fit restraints as an upgrade the stock mounts are the most reliable and more than capable

Ok cool, I'll look into them.

SC Power do em

A few years ago I noticed my original engine mounts were presenting visible cracking of the rubber, while they were still performing well enough I decided replacement was sensible as a precautionary measure, so as part of my ongoing schedule of maintenance and continual improvement I fitted these.......

Which TBH can only be described as, errrrr..... really rather expensive!

However on the plus side they did stiffen the engine location/security nicely and two years on they do seem completely impervious to heat, saying that I have no cats and run 18 degrees of timing at idle so they definitely have a significantly easier life than on a Chimaera running 10-12 degrees with all three cats still in place.

Disappointingly with these 'reassuringly expensive' engine mounts fitted my engine now sits a few millimeters lower than it did on my cracking but still serviceable standard rubber mounts, it's not much but was enough to mean I had to move away from using the longer body synthetic media V8 Oil Filter. It also puts the manifolds a little closer to the chassis rails which while not touching are now what I'd describe as 'Tight as a Nun's Chuff', and lets face it... it's not like TVR provided much clearance here in the first place.

Apparently what I need is a lifting shim kit, really!!!

Honestly I don't think it's unreasonable to expect after paying a small fortune for these engine mounts that they would at least leave my engine sitting at the same height as it did on my 22 year old cracked originals

I now feel I probably could have saved myself a good chunk of cash by just going with some quality standard engine mounts, even genuine Land Rover mounts would have been cheaper and I'm sure would do the job perfectly to give another 22 years of service as did my originals. Given I already have far lower manifold temps than a standard Chimaera I now can't help feeling these expensive SC-Power engine mounts may well have been a solution to a problem that no longer exists

The SC-Power engine mounts did stiffen up my engine location and are probably a very high temp resistant fit and forget part, but do we really need these benefits? What I wasn't expecting was they gave me an engine that now sits lower than it did on the originals, this alone left me a little disappointed especially given the price I paid. I'm not saying the product is bad, they work just fine and are staying put on my car, it's just I always feel it's important to give my honest objective feedback to help my fellow TVR enthusiasts make informed decisions on the parts they fit.

Hope it helps?

I have a late car on standard mounts I installed about 4 years ago. The longer filter your suggesting didn’t fit or was so perilously close to my chassis as to not be worth the risk. My engine clears my rails by a good 10/13mm so on my late car at least it doesn’t work.
I wonder who else has these filters who can’t use em.

Isn’t these metal protector things going to attract heat towards it hence heating up the rubber anyway. It all sort of neutralises our after an hours drive as everything’s hot unless you run Mbe which will keep everything very cool

[motul1974]

Thanks guys for your feedback.

[phazed]

I wonder if the SC power mounts are made a few mm smaller so that you can squeeze the restraints in?

[bobfather]

I've avoided SC mounts simply because I'm aware that the metal supports could concentrate the heat on the elastic parts and retain the heat for longer

[phazed]

I have the SC mounts on their own fitted but had to fit a shim on the nearside so that the manifold would clear the chassis rail.

Actually I have no idea what the clearance is with my ACT manifolds, I must have a look!

No idea mate, what I can tell you is I ran the V8 filter for years and years with no clearance issues once fitted, I must have got through five of the things over those many years before fitting the SC-Power engine mounts, which in turn forced me to switch to the shorter Royal Purple filter that also uses synthetic filtration media.

I know of plenty of other TVR owners still happily using the long V8 filter and others like you who say it won't fit, I conclude as with all things TVR we must all except these cars are a very long way off being dimentionally consistent. It's a bit like you have to accept there may be a par of breasts scribbled on the underside of your dash, we all love these cars but no one can argue a TVR is a Teutonic German made piece of constantly accurate engineering contructed in a well disciplined modern production plant

Personally none of that worries me, I'm just proud to drive a car with a big pair of norks under the dash

[Classic Chim]

I can’t remenber what year and first thought it was only the Malaysian chassis/ body that used the 5 or is it 7 mm shim on the n/s mount to raise the engine slightly but seem to think plenty of earlier cars have the shim too.
Hand made cars for you great to have boobs under the bash and in many cases in front with the average age of the owners

[N7GTX]

My '94 has the shim as standard. But the mounts were still allowing the stainless manifolds to get too close to the rails and eventually one side was just touching, causing vibration through the car.
So bought these from Powers and in the end after much changing and swapping around to get the engine level but clear of the rails on both sides, used just the one.

Good to know, thanks.

[brownspeed]

I see you're Cheshire based; Have a chat with Ian at TorqueRVT. he will also fit them if you're not inclined to do your own.
He supplies the upgraded mounts (my Tam* was doing a set of the original chocolate mounts every 18months) there is slightly higher vibration transmitted but its not intrusive.

• ok its a speed6-but I'm sure its the same principles

[motul1974]

Many thanks to everyone. I've taken on board the general views a d I've now had the opportunity to have a good look my existing mounts and they look in very good nick, so I'll save that money on petrol!
