I’ve tried them on an MR2, they’d be fine for something like a Mondeo or Corsa but not really for a sports car. BTW to update this thread my daily now has MPS4 on so I should be able to give a long term view in a month or so.

Drive one first, but be aware that the slush 'box in the 370 isn't remotely close in speed to the 458 or 488. Bearing in mind the manual has rev-matching, if that's what you want it for then that may be a better option. I don't dislike auto boxes with paddle shift, but it has to be the right car personally. I loved my 911 which was PDK and tbh I'd buy another one in a heartbeat, but I wouldn't want an automatic Elise. Half of the joy of the 370 is the fact it's so old school, so I'd have to stay manual on that one. But hey, try them both and see

It won’t from May 20th onwards, that’s a specific fail now. Also with the light on permanently you've no idea if you've got other faults...

Says the man with a billion word essay on which bucket is best to contain the water to wash your car with

Hang on a mo... The dyno graph on that company's website is the exact one you linked to earlier. So was that your car they did that to then? And after a bit more digging, I found that Mazda once created a proper hydrogen RX8, not just an injection device: https://www.carmagazine.co.uk/car-reviews/mazda/mazda-rx-8-hydrogen-re-2007-review/ . If you read that in detail, it explains why a rotary can take hydrogen better than a conventional 4 stroke engine (which is good, and not something I'd thought of), but it also shows that using hydrogen meant that power nearly halves from 192bhp to 107bhp, and a similar drop with torque from 162lb/ft to 103lb/ft. Now obviously there's a difference running an engine entirely on hydrogen to simply injecting a smidge into the combustion chamber, but this isn't helping prove anything here in terms of extra power. Go to the test results page at http://www.hydrogenhybrids.uk.com/test-results/ and have a read of the 'facts'. You have one letter from a biology teacher with the most god-awful evaluation of his test and evidence that I've ever seen, and even his own results show that immediately prior to the install on two occasions he got better fuel economy than on 6 out of 7 runs after the install. The bike and Focus power tests are a joke, as the bike showed a whopping 1bhp increase (which anyone who's done a dyno will know you can easily get between runs anyway) and the Focus a whole 3bhp more which is a whopping 2% increase on max powerzzz!!!!11 If it looks like a duck and quacks like a duck... I mean, fair play to you for trying but I'm not convinced this is anything other than all in your mind in terms of any difference at all. Out of curiosity, what did your insurance company say when you told them about the install?

Or even better move to a chargecooled setup.

I reckon once you get yours fixed and sorted you’ll be as happy as anything, and forget all about wanting a V8 swap in the Zed.

Trouble is that even if you do sell up and go V8, you’re still going to be spending a lot of time fault finding and dealing with niggles, so if that’s what’s getting you down about this build then it’s not going to be eradicated by swapping for a V8 kit

Thanks. Precious little info there though, I was after details like what is the kit, and most importantly was the car mapped for it?

If there’s evidence, post it up. The only info I could find had zero evidence and claims it was only useful at high rpm, which makes sense given it’s trying to reduce intake temps the same way as water injection. If it cant cause problems, I’d suggest it’s not capable of producing results either. Do you have dyno graphs before and after? Was the car mapped for it? Which kit did you have?

Which June?

The Toyotas won by over two laps from the next LMP1 car, the Rebellion car. And that's just at Spa over six hours, imagine the gap at LM next month! Toyota will almost certainly finish first at LM, but it won't be any kind of a win at all. And noting that Conway (who is a bloody quick driver in that car!) didn't even try and overtake Alonso makes me think there's some very obvious team orders just for publicity reasons there too. I have zero respect for Toyota carrying on this year. Shame the new AM Vantages didn't finish a bit higher up, but I suspect that's down to BoP not being remotely sensible yet. Hopefully they can get it right for June, I'd love to see a proper battle in GTE with the AM and BMW taking it to the standard Fer/Por/Cor trio.

I just had a look into that stuff. Basically it's meant for diesel engines above anything else, as it encourages a lean burn to potentially save fuel and in theory it'll turn from hydrogen into water as a byproduct of the combustion process to lower engine temps/EGT. In theory. Given the potential benefit vs potential risk, so a bit of fuel saved vs melting pistons by running unexpectedly lean, as well as the complete lack of any independant research into it on diesel engines (which is what it's designed for!) rather than petrol engines, I'd be filing this firmly under snake oil and removing it from the car pronto. Incidentally the few pages I've read about hydrogen injection refer to it being only of benefit at high rpm, which would indicate a relative lack of involvement in helping mid-range torque and certainly it's not going to be doing a damn thing unless you specifically map for it.

Who?

That was me he was a right numpty, nothing bugs me more than people who won’t move over for faster traffic, track or motorways.

Do I need a whoosh parrot here or something? You have a what installed?

I think it’s Lotus owners keeping Rover parts in demand these days

A fast car is not always a fun car.

Buy any old one and get a new plate made up for it

That's the thing, in the dry I agree with you: There's not much between the EF1 and MPS4. In the wet and changing conditions though, it's night and day. I've driven budget tyres with more wet grip than the EF1s, I really don't rate them at all for that. For £57, why chance it? It's not even a tank of fuel.

Well aside from dodgy Japspeed manufacturing, then yes they should still fit

Depends. They should be, is your Y-pipe OEM or aftermarket?

I can't read that company name without making race car noises... "Braum braum, neeeeeooooowwwmmm!" *gets coat*

They're not known as Crapspeed for nothing... But yeah, it seems that there's a big issue with hi-flo cats and the quality of them for the Zed. So, so many are failing MOTs that tbh I'd either stay stock or just go decat and swap the stock one back in come MOT time nowadays.

This, in spades. If Tesla and their closed ecosystem go, Tesla cars are going to be extinct overnight.
