Feedback on our 4.6 litre engines.


Hi Chris, I'm Bart Callens from Tunisia. I must say the 4.6 you delivered to me summer for my Defender 90 is great. I don't regret I took the 4.6 instead of the 3.9. in my Defender 90 4.6 EFI (with tornado chip)



Racing 4.6 Range Rover in Barbados

Hi Chris, just a short note from down here in the land of eternal sunshine and coconuts with rum in them. My 4.6 that you built for me two years ago is still going strong. By the way, I am wheeling a fully rebuilt 1972 Range Rover and it goes like a bat out of the tropics.
Thanks

Hi Chris, Some months ago, I had the good fortune to let your guys have a 4.6 bottom end to build up for me. Piper cam, new timing chain, mains, etc. with stage 1 heads and a weber carb.
Well it was installed into my Landrover lightweight hybrid
Before, I was as happy as Larry, whoever he may be, NOW, I'm even happier. The down side of course, is the fuel consumption has taken a turn for the worse. I must stop using the performance quite so much!. The bottom line is, thanks for the motor, your guys did me proud! The local GTi brigade are less than happy with the 'old' Landrover that leaves them at the lights though.
Thanks again, Alan Hodgson. U.K.



I installed the new engine about 2.5 weeks ago. The difference between the 4.2 and 4.6 is like night and day, granted the 4.2 was pretty tired and neglected by the previous owner.
The engine has a very smooth idle yet the torque band is much broader thanks to the RPi/Piper cam. Off-line acceleration is fantastic and it feels like the engine will continue to pull until it runs out of road. I haven't done a 0 to 60 test, but it is on my list. The Headman headers have not been installed as of yet, I needed to make sure everything was good to go.
Even with all the performance upgrades, the 4.6 passed our smog test with flying colors. We thought it might run a little too lean due to the stock computer, however, according to the high RPM part of the smog test the CO and HC are right on the mark though I am still thinking about the chip upgrade. A quick rundown of the items I purchased from RPi is as follows: 4.6 short block Performance cam and timing kit, Head rebuild kit with Stage 3 valves, used rocker assembly, one set of valve keepers, Headers, not installed as of yet, and Gaskets. Items completed out here: All new valve seats installed with 3 angle grind Distributor re-curved Intake trumpets shortened and polished High performance 8mm ignition cables Let me know if this is an option.
Sincere regards,

David Golumbic USA



Chris, The 4.6 Stage III we put into the 1995 NAS Defender 90 Station Wagon now has plenty of break-in miles on it, and we took it to the track today. Stock 3.9 in this 90 ran 12.5 seconds 0-60 The 4.6 ran a best time of 7.78 seconds 0-60 this morning! Wow!
Owner of the D90 with the 4.6 called today to say how much he loved the truck, Said he towed his 26' boat home in 5th gear at about 85 mph, and could never tow the boat over 4th gear before. We have decided to keep ECR on the upper end of the RPi scale, so we will only be working with 4.6s and other performance mods, and some 3.9s. and will continue to do high end engines with you for a long time to come I think.
Mike. ECR Main USA.



Hi Chris, the engine I bought from you is great (4.6, stage 3). My car is running like compressed air. In a few days I will send you two photos of engine and car (MG). Thank you. Regards

Hope all is well. We had our first nice spring days yesterday and today. I took 4.6 Moggie (Morgan) to the airfield and winched up my paraglider for the first flight of the year. Fantastic thermal conditions so I climbed rapidly to over 6000 ft and went away with the winds. Landed far away from home near a petrol station. Got a hike with two nice girls back to the field. Invited the nicest to a racy/tourqy tour in Moggie and it ended up with a successful date thanks to the enormous RPi 4.6 power ... (even all other Mog-friends are impressed). The engine performs perfectly. The oil now stays clean as syrup with no consumption and I feel the engine has started to loose up. Lovely!
