great simple modification
from Anonymous on 13/02/2018
just fitted it took half an hour to fit. fitted boost pin had slight smoke under load. just taken it for a spin the smoke has gone and it feels more responsive throughout the gears, pulls stronger mid range. would recommend this simple mod alongside the boost pin...

Top Tip, do not try and fit this over a gravel drive...If necessary, put a tarp down first to catch the shims / springs if needed.
Have fitted mine with 3 Shims in place, I have had a boost pin fitted for the last 2 years. There is a difference at higher revs, I notice it most about 50 to 55MPH it feels smoother. Next step is to remove a shim and see how that feels.

Easy to fit pin and ring, simple, clear instructions. Very subtle improvement, significant power increase, engine feels snappier at all revs. Appears to have actually reduced the amount of smoke! Very happy, recommended def, do Fourby do any other 300 tweaks?

Been in a couple of days and is definitely allowing the motor to rev up quicker in the higher register. Has given the 300tdi a little more top end power. Instillation is quite fiddly but doable.

Excellent addition to the boost pin with larger intercooler.

Easy to fit ,I have the Bosh boost pin and now I can see the difference again, It is only necessary to make some adjustments in the pump and the turbo to have the best performance, very easy for any mechanic

I already had a boost pin from another company so wanted to try the boost ring as well.
It was a right pain in the arse to fit as the washers keep falling out.
I can see no positive difference if anything it feels like I have lost some low end power. I currently have the 3 washers recommended but am unsure if changing this would change anything.

Bit fiddly on 200tdi to fit but well worth it transformed the motor fitted with a fuel pin makes the motor fairly lively through all the Rev range now I’ve just got to fiddle with the shiming to get it just right but fantastic so far another quality fourby product thanks
Great ! Really made a different defender seems to have more power for less throttle input and feels smoother, going to try a boost pin next

Easy to fit and set up,especially as the video explained everything and LRO featured it this month.
Drop in replacement which really made a difference

Was a little fiddly to fit on my 200 tdi due to some very stuck bolts. My 200 tdi only had a single spring which i believe is common, so don't worry if the video showed 2 springs. I left all 3 washers in and it made a massive difference to the performance. No visible smoke on my stock pump and a nice increase in power. I've since installed the boost pin too which made a difference but not as much as the ring did.. Go get one!

notice an improvement midrange where I need it, thanks
Great, easy to install

Fitting is easy enough results are astounding. car is smoother to drive and pulls easyier. economy also improves as your not having to thrash engine all the time

Fitted this and Morgan Hill boost pin to my Range Rover Classic 300 tdi and the result is incredible!!! I didnt have to tweak the pump..no black smoke..fitting the boost ring it’s not very easy because you need to remove the Ac compressor to get enough space to mount it..

fitted to my 300 tdi ccv truck and it pulls like a v8
from James Barlow on 13/10/2017
Fantastic old fashioned customer service. Which makes a change. Package arrived as promised without any problems. The Boost ring kit is of a good quality and everything fitted as per the very informative Youtube video.
Well done to all of the Fourby team. I look forward to using your services again and I will be recommending you to others.
Please keep up the good work and quality of your products.

My 200tdi Defender has never gone so well! What a transformation. I am so impressed with the quality of this product, no smoke but plenty of poke! I've already ordered the boost pin to go with it, thanks for the fast delivery Fourby. Will be back for more!

Fitted it onto the fuel pump of a 200Tdi Disco engine in an LR90. Couldn't reach the lower right bolt without removing the crankcase breather thingy, so took more time fitting, but the result is absolutely fab, engine runs a lot smoother. Definitely going for the boost pin now too!! :-) BTW, in there was only 1 spring in this fuel pump.
Well worth the money
from Anonymous on 28/07/2017
Easy to fit and a noticeable improvement. in the 40 to 60 mph range the 90 keeps accelerating.
from Anonymous on 27/07/2017
Great product !, ease of install but would have liked that you supplied 2 o rings to eliminate using 1 old one that could possibly leak . Does what it says
Very happy with the results
Good product works well

I've had the boost pin fitted for a couple of years now after fitting the pin my land rover did smoke a fare bit but after seeing the comment about the boost ring stopping the smoke a good bit I thought I'd give it a go, I must admit I had trouble getting the bolts on my pump undone but once I had the ring was easy to fit, once fitted I gave the landy a blast up the road a lot of the smoke had gone I am please lol.
Spoke to Neil at kelmarsh show about tweaking things a bit more so hopefully once I get it sorted it will be 100% perfect
I'd recommend the boost ring to anyone
from Anonymous on 25/07/2017
Not at all impressed with this. I received the boost ring a couple of weeks ago and it made my truck smoke more! I have tried with taking shims out and having all of them and it does not make a blind bit of difference. I was stopping several times whilst driving it to try and sort out the smoking issue which has resulted to me removing it and to no surprise it smokes dramatically no where near as much! I would not recommend this product.
very good improved rev range gave better driveability
from Anonymous on 24/07/2017
Works really well .has extended gear range somewhat and has removed some smoke from the boost pin and adjusted pump I'm running .happy to recommend this product

I fitted a boost pin a few months back to my 300tdi discovery, and noticed a vast improvement of power to my very sluggish truck ..
Then I was notified by neil that they also sold boost rings. Not knowing anything mechanical about cars and engines and that sort of stuff .. neil started to explain about how things work and how it would improve my trucks performance a bit more .
This I had too do so I purchased a boost ring from fourby.
Neil went thru my fuel system and fuel set up to make sure it was performing to its best so once the boost ring was fitted the difference would be noticeable..
Well WOW what a difference it made .. totally transformed my trucks power
The difference is night and day ...
I would recommend these quality products to anyone wanting better power performance from their truck ..
Thanks guys for a great product yet again and all the help and advice given from you
