Fourby Boost Ring - Dyno results - 25% more power

[@noelmcelwe]

Your products are incredible…. Fantastic results, simple to install for the DIY mechanic and very reliable! British engineering how it used to be 👌🏼

[@scaryfakevirus]

If you are increasing the distance between the cap and the base and then adding internal shims surely that just balances it out to how it was originally set more or less?

[@red90rover98]

Would have been nice to do the pin only first and then the ring. Everyone knows what a pin does, but there is nothing out there on the ring other than seat of the pants.

Greetings from South Africa. I was born blind (in 1994) so I unfortunately can't drive but if I could drive and if I had to do a0-100 km/h (0-60 miles an hour) I would do this the way you did the first test in this video.

[@fortnitefred1351]

How did it affect MPG?

[@Bugoutvehiclesuk]

Great bit of kit.

[@jackplant9232]

Does this increase emissions, how does it affect MOT?

[@evanjones2539]

Leave plenty of slack in the throttle cable...............!!

[@motoninja2747]

Thanks for the informative video something I was told was doing these 2 items makes the egt skyrocket to dangerously high temp risking engine damage also what’s the smoke like as I currently don’t get smoke at all and dose it effect fuel economy? I currently get about 29-30 mpg

[@ejc8858]

It's not too bad, I mean Defenders for instance have quite a good stock cooling system so it won't cook anything unless you're ragging it. Best idea would be to upgrade intercooler and set up a few more gauges to make sure the temperatures are good

[@whitacrebespoke]

That Craddocks in Beoley?

[@jeremylakenes6859]

I just installed a Boost pin two days ago. What a difference. I just installed the boost ring....I really can’t tell a difference. Maybe it’s more smooth in the higher RPMs, but it’s hard to tell. I hit 700 C on my EGT pretty easily just at the top of 3rd gear. What do I do next? Not much smoke.

[@MD_13b]

Hybrid turbo and bigger intercooler 👌 the Hybrid turbo should lower EGTs if you run the stock 15psi

[@jeremylakenes6859]

Matthew Downes I have talked with a few other owners and my top speed is 122 km maxing EGTs. I was told by another guy whobhad the same problem that once he installed new injectors, he went from 120 top speed to 145 easy. Given the higher miles on the engine and lack of maintenance from previous owners I believe this might be a good next step.

[@deuskariisa3382]

@@jeremylakenes6859 What size of injectors

[@jeremylakenes6859]

@@deuskariisa3382 Factory injectors, but I just had Bosch rebuild them. That made a large difference. My EGTs go up quick still

[@kevinlovelock2515]

hi great bit of of kit but where did you get the dyno meter from please as i want to do a similar experiment

[@Fourby]

Google 'Gtech Performance Meter' ...you'll find them

[@kevinlovelock2515]

hi thank you for the reply

Hi was this with other modifications if not can u do this without others

[@ricardo_0085]

What about using only the boost pin?

[@Fourby]

I’m filming that, watch this space

[@mbtech9791]

Very good video, when the warranty has expired on my newly fitted injection pump, you have a customer.

[@mad7shark1]

Hi, how valid this can be when you do 30-50 in the second and third gear and after the installation you are doing the same test only in third gear? So your gain is actually shifting time lost in the second measuring..

[@RobsClips1980]

I would love to see the same video but with the boost controller added to the mix.

[@bedmember]

How much does it affect fuel economy / consumption?

[@AB-jz6hd]

Keith Tan Hi do anyone know how much it affect the fuel economy?

[@ejc8858]

The boost pin is the only part that would increase fuel consumption because it lets in more fuel. However the argument is that you get an earlier boost from the turbo so it counteracts it, for instance short and heavy blasts will use more, whereas motorway mpg will be better. The boost ring only increases combustion by adding more pressure, so in principle it's probably increasing mpg rather than decreasing...

[@nathan6294np]

fitted one today (boost pin already installed) if anything the engine is a little rougher and although it picks up a liitle quicker / lower down in the rpm theres no chance it adds 25%

[@Sarin-Dan]

Would be nice to see it on an actual dyno

I know Im asking randomly but does anyone know of a trick to log back into an Instagram account? I somehow forgot my password. I would love any tips you can offer me

[@orionmalik3120]

@Sincere Wilder thanks so much for your reply. I got to the site through google and Im waiting for the hacking stuff now. Seems to take quite some time so I will reply here later with my results.

[@orionmalik3120]

@Sincere Wilder It worked and I now got access to my account again. I am so happy:D Thank you so much you saved my ass !

[@sincerewilder3458]

@Orion Malik happy to help :D

[@MartTheMadScientist]

one day when my misses stops buying windows an shit ill br able get myself one lol great vid

[@CriticalMick]

How does the boost ring affect smoking? I noticed my 300Tdi disco smokes under load with a boost pin in and I was wondering if adding a ring would make it worse. Especially with the upcoming changes to the MOT rules.

[@Fourby]

The boost ring will improve the smoke, as it allows a more complete burn 'inside the cylinder. that's what gives the power

[@dysekmarcoski4730]

what about boost pin, boost ring, hybrid turbo, gas flowed inlet/outlet large intercooler and open race pipe? 25%.... no more like 50!

[@neilwhite8131]

Nice to see the results.. LOL. ..how many washers did you have fitted on the ring??

[@Fourby]

2 on this

[@neilwhite8131]

Thanks Neil, I have changed mine to 2 washers as well.

[@stevesmith7530]

How about real world figures for people who do not use outsized MT tyres? The gearing upset caused by them can be huge

[@Fourby]

Steve Smith the gains would be even greater with correct size tyres.

[@Mike-yq6jg]

great vid many thanks

[@trevornokesmusicltd5357]

Good vid only the gain from 30 to 50 is 0.7 sec not 1.5 sec.....Still a good gain though.....Sold :-)

[@Fourby]

We've both got it wrong Bandit. If you watch again. The number was 5.08, not 5.8, which is a 1.42

[@trevornokesmusicltd5357]

No Problem, Just sorting out if mine already has both items, if not an order will soon be arriving. Good work with the vid's, Keep it going :-)
