Twin Turbo Tuesday Episode 17 - Twin Turbo 4.6 V8 Range Rover P38 Final Dyno, 0-60 run and results

[@AMERICANA-BOOMSTICK]

How much power can those transmissions take? 😂😂😂😂

[@isaig.9222]

I second this question

[@jblack5323]

An LS with a injector removed would destroy this.

[@kevinblaylock9883]

From the factory the 4.6 was under powered! This is how it should of been ! Great job!!🙂👍

[@nickblake8041]

I had one with an ls 1 5.7 250 bhp 300 ft lbs loved it .thinking of looking for anothe Holland and Holland and having another one built.....

[@terencemitchell5110]

Hi i have just got a p38 4.0 in your opinion would a svr engine go in one of these. i really think it would be a a beast and quite a bit if fun with that running gear in the p38

[@ianwiggins8782]

And down which is all that cost you to do that how much did it cost you to do all that work on it

[@ianthurtell1342]

Thousands in parts and hundreds in hours. We will offer such conversions for our customers however its a bridge too far for many unless the desire for incredibly drivability from a P38 or other Rover V8 powered vehicle is truly desired. For many though there are upgrades to the naturally aspirated engines that will improve things.

[@johnkemple]

Happy to see it done Ian. It has been a pleasure communicating with you over what is now years. My 4.2 Liter rover runs as good as it possibly can. I still have not installed my larger valved heads. But I won't be keeping up with your twin turbo any time soon. Great job!

[@ianthurtell1342]

Cheers John.

[@bobbyshaftoe]

Changing those plugs and those leaky valvecover gaskets looks like a LOAD of fun :-))

[@danielvanoosten8987]

Great results, I will likely do the same but with a single turbo and dedicated petrol. One thing I think you missed when you spoke about the walbro pump and pressure reg was injectors? Are you running the stock ones or upgraded? And is the AFM from m62 or later n62 4.4?

[@ianthurtell1342]

I mention the injectors at one point. They are a 12 point injectors which handled the additional pressure far nicer than the stock ones but they did need the loom modifying to fit. Of your going to carry a conversion like this or any other kind of custom setup my advice to you would be research and learn as much as you can about everything you are changing. Also key point is talk with the guy doing your tuning. If your in the UK you can discuss with us or mark at tornado but basically the ecu setup is going to govern the map, injectors, fuel pressure etc that you can run

I have a relatively clean nice 99 4.6. It is fast enough for me already 😂

[@richardschofield2201]

So no more See U Next Tuesday? Very sad. Great series. Enjoyed it.

[@davidedwards3724]

I like the idea of more power ,less lpg , it does pick up very well . Impressed?!

[@philiptyson4000]

Did ashcroft say they could beef up a special box ?

[@Predator27007]

The dyno figures prior to turbocharging seem curious; 240bhp/255ftlbs. We're the quoted factory figures of c.220/277 or 300ftlbs for Thor, rather inaccurate?

[@matthewcoupeofficial]

Factory the 4552cc 4.6 is 218PS and 4.0 is 185PS so that is odd.

[@michaelbolt4530]

😎😎you guys are literally living the dream

[@ianwiggins8782]

And whereabouts is your LPG tank is it in the boot where a spare wheel goes

[@ianthurtell1342]

Yes where the spare wheel normally would be. Plan is to make a rear bumper with a swing arm for the spare (If I ever find the time)

[@FunkmeisterOfSedgley]

Thoroughly enjoyable. Thanks.

[@philiptyson4000]

Well done goal achieved ! What would you say about cost? Is it comparable with the simpler supercharged procharged method? Are you planning on making this mod available to customers ?

[@RPIEngineering]

Hi Philip, Please email [e-mail] for a quote

[@baloghattila3287]

Big end bearing stock?

[@edwardsayers541]

Is it more fuel efficient to?

[@f88pvc]

stunning build enjoyed every minute

[@sandyjonesmusic]

Magic, well done!

"Picks up like Don Juan in a brothel!" I know you've maintained all along it's NOT about the BHP but I reckon you should do a Run What You Bring at Santa Pod! I had to get rid of my P38 4.6 years ago and miss it like mad but just the road tax for one here in Ireland is €1805/year! Before it went I did manage a RWYB and got a best of 18.05 seconds at 76mph. It certainly wouldn't set the world on fire but I had a great day out. Also, have you tried it in Sport Mode yet? Sad to see the end of this series looking forward to the next project.

[@ianthurtell1342]

Funny that. RWYB starts in October 😉

[@ianthurtell1342]

Yes sport mode just as fun and will play a bit more between the two but knowing peak torque is better a little lower down than 5500 rpm means might be better on the 1/4 mile etc in normal mode. But I'll play on the day

[@ianthurtell1342]

Here's the santa pod video for you lol kzbin.info/www/bejne/rquYZa2Od86Bq7M

[@CaptPegg]

How much s the Turbo conversion?

[@RPIEngineering]

Hi, Best to drop us an email with what car you have etc so that we can best advise you. [e-mail]

[@DarknessYT2010]

Cost ??

[@charlyp.8168]

Respect!!!

[@keithpvt]

Sweeeeeet!

[@2510RANGE]

Amazing

[@MuNGusTik]

really close to standart sec 0-100

[@RPIEngineering]

Well over 2 seconds faster, but as pointed out in the whole video build this was not about big numbers etc it was done for mid range driving power. Which this has by the bucket full.

[@MuNGusTik]

@@RPIEngineering thx for answer why dont choose charger? and do you explain in videos how you change fuel mixture?) very interesting)

[@RPIEngineering]

@@MuNGusTik Yes this is all explained in the video series. Several people have gone down the supercharger route however I wanted to do twin turbos as I didn't want the engine driving a blower along with a few other reasons.
