Defender Td5 GTB550 on a Darkside Tubular Manifold - Shocking Results!

- We had this Td5 Defender 90 on our dyno, two years ago, almost to the day, whilst setting up its awesome GTB550 VNT turbo.
Originally making a healthy 250hp and 581Nm when we first installed the turbo, with a CJM exhaust manifold, we were keen to see if this five branch tubular manifold from Fabrication Mafia (Darkside Developments) made a positive improvement?
Its safe to say, the results were not what we expected! Grab a brew and settle in to your favourite armchair, as you join us on this epic voyage of discovery!
Same issue with mine. Has all the right parts in all the right places, just not makin that power like I should. I am also smoking throughout the pull. Will make some modifications to my head and go through with my diagnostics before I plan to ship you all my ride…
The rolling road tells the truth!
Love these big power land-rovers
Thank you!
Got one of them on mine but with a GTB2260 VK ,needs setting up correctly need to take it up to Carlisle to be done.
Great video!
Thanks!
Interesting. CJM is better than a stock manifold though?
There’s very little difference between the stock exhaust manifold and the CJM manifold in terms of performance potential.
The cjm exhaust manifold is slightly better than stock as the runners flow nicer much like an AMC head vs stock. You wont be hitting the limits of the exh manifold with the gtb550.
How many kg/h air is the maf measuring? Have you made any data logs and seen if the turbo is pushing the air into the engine based on the rpm, boost and maximum pumping volume?
We have many data logs from many different specs of high powered Td5, as we obviously log everything we run on our Dyno. Stay tuned as this car will be back soon enough and we’ll post an update then.
I emailed you about mapping my puma with a dark side intercooler on and a stage one hybrid turbo it’s a 2.2 and you said it’s something you don’t do but this is modified quite a lot
A hybrid turbo will not work on a puma. The end! We’ve spent a small fortune testing and developing turbos for our own cars, many years ago. We’ve actually listed “hybrid turbos” for Pumas on our website, but they’re not available to buy. Read the product description and you’ll understand.
The simple fact of the matter is, If we don’t sell it, it’s not worth having!
@@alivetuningltd amazing at least youve gave ma a reason why you dont do it instead of no explanation
ANOTHER GOOD VIDEO IF IT WAS MINE THINK I WOULD STICK AT 250 BHP LOOK FORWARD TO SEEING IT AGAIN THANKS
Glad you enjoyed it
