WE DYNO THE RABBIT!! - MK1 VW Rabbit Turbodiesel (4K)

Olly & Co take the rabbit (turboed, intercooled 1.6L diesel with propane injection) over to TMS diesel to be dyno tested! Three power runs, lots of smoke, and a baseline for future modifications.

I'll watch every video man. Love this car and this is a bad ass Chanel. Thanks for the videos. Ever considered going BEW?

[@OliverFetter]

Thank you! I have toyed with the idea but also lots of other things haha so many cool things to do so little $$!

He probably doesn't want an engine with premature cam failer on the injector lobes

[@dylanfox7077]

I love this series!

[@dylansessions9027]

Awesome vids I’ve watched them all! In the process of bringing an 84’ rabbit 1.6td back to life and saw how you had that sweet looking dash… do you make that or is that something I can purchase somewhere!? Keep the vids comin!

[@OliverFetter]

Thank you!! That dashboard is some homebrew haha but you can buy fiberglass blanks on the interwebs.

[@UngluckInc]

It is always scary going to a place with a dyno and they have terrible fans. Regardless, nicely done sir!!

[@OliverFetter]

Yuhhh spooky af

[@lukesherrill2499]

80 is solid for the 1.6l td. The 1z/AHU 1.9l tdi makes about 90 stock! So not too shabby at all for a car that weighs nothing

[@fastinradfordable]

I mean. A 1.6td made like 70hp new… Stock. An ahu with a Mk4 turbo and now we’re talking. Bolts in like stock. Except you’re making 70hp at 1500rpm And easily making 150hp with stock reliability. .

[@fastinradfordable]

Come over to the dark side. Ahu Tdi can make 100tq off idle ;p

[@lukesherrill2499]

@@fastinradfordable oh and it’s gonna be mtdi too

[@MrTheHillfolk]

@@fastinradfordable try like 240 ft pounds at peak. At least thats what my tdi-M had in my old rabbit.

[@OliverFetter]

I mean.. if the point of my project wasn't to work with the 1.6 I wouldn't waste any time with a tdi. I would just go straight for a 1.8

[@mirzaosmanovic5430]

on my 1.6D without turbo factory factory engine 40kw, I put a 1.9AAZ engine head that I had to modify so that it could fit on that block and turbo GT2052V AND FACTORY BOSCH PUMP turned on max fuel, it ran like crazy over 6000rpm (second gear 100km/h) and at 3.5 bar pressure, the turbo's head gasket broke (paper) and then I reduced it to 2.5 bar and drove like that for 8 months at full throttle every day and then the disaster happened on the oil pump cam and now I'm doing the whole general job adding sprinklers to lubricate the piston and oil cooling, conversion to metal head gasket and engine bearings from 1.9tdi and I will drive at 4.0 bar turbo pressure and element in bosch pump 12mm and videos are coming soon my advice mate, just give as much air and fuel as possible and that's it, no special parts

[@OliverFetter]

How do you run max fuel without horrible rev hang??

[@ryangregory6306]

Love the build! I have an 81 na. No turbo just yet! Lol however I was curious about your rim and tire setup?? Love the stance and look.

[@OliverFetter]

Tires are yokahama S drive's - no complains there great non-track tire that still hooks up. The wheels are 15x7, +35 offset.

[@fmsprojects0000001]

Out of curiosity what kind of mpg are you getting now?

[@OliverFetter]

Current day (quite a few changes after this video) I'm getting about 35-37mpg driving with my foot in it

[@jordrider1917]

Aren't they supposed to have a big ass fan blowing at your rad? Also maybe run an air to water IC since it seems like space might be limited.

[@OliverFetter]

Yeahhhhhh... Somehow no one on scene (incl myself) thought of it right when we started

[@metalhead760]

So AAZ numbers basically, but at the wheels. Not bad.

[@OliverFetter]

Exactly lol

[@yako0000]

sweet rabbit. i have a 79 german rabbit that i turned the pump up all the way on. 48 hp stock, i figure i'm pushing 60 now lol.

[@OliverFetter]

Sick

[@darrentylor5473]

What is the redline? Do you think that failure was just the end of the available powerband? My redline is 4200rpm so just asking...

[@OliverFetter]

As far as I can tell ~5k rpm is a good ceiling for the valve train not exploding. We took these pulls to about 4200. Although you could rev higher these motors make peak hp somewhere around 3800-4000rpm.

[@herkybc130]

Looks good!

[@OliverFetter]

Thanks dawgie!

[@Eeriekn1te]

75 to the wheels in 5th* thats the overdrive gear I thought most dyno pulls are done in the 1:1 ratio gear usually the fourth gear on most 5 speeds?

[@OliverFetter]

We checked ratios beforehand.. I don't think it matters too much as long as the computer & car are consistent

[@calwick1621]

I’m throwing an 81 rabbit together and I’m planning on just gutting the interior like yours. What did you do to reduce road noise? Bed liner the floor?

[@calwick1621]

Also curious on the wheel/tire setup and how far it’s lowered, looks rad!

[@OliverFetter]

hA HA hA ha HAAAAAAA I'm not sure what you mean by reduce noice HA! But actually the rabbit has no sound damping anywhere and is genuinly loud AF inside. When I drive it I put in earplugs lol. Bedliner just makes it look nice and keeps it from rusting.

[@OliverFetter]

@@calwick1621 Honestly I'm not sure how low it is... Its got 15x7 wheels, I like to leave about a finger or two of room between the fender and the tire to avoid bottom outs and roll the crap out of the inside of the fender.

[@calwick1621]

Hahahahah sounds good, I appreciate the reply!

[@trev0rbr]

Do you have any pump mods done? You should be able to break 100whp easily with out any propane

[@trev0rbr]

What ever happened was probably because of the propane, it can cause pinging and preignition its really not a good power adder, stock rods can easily handle the power you're making there. You have a good setup as long as you have a good pump or tune your pump well you should be able to make a lot more than 100whp but if you're going over 125whp I'd recommend a bigger pump head 10mm or 11mm and 150-175whp would be easy then too. With your turbo and intercooler it's possible and its been done many times

[@OliverFetter]

@@trev0rbr The pump is modified (Giles) - no gov, swapped diaphram pin, etc. I've run into the issue of only being able to turn the fueling up so much before idle RPM is to the moon - curious what your thoughts are there. Certainly there could be more fuel during a heavy pull & more power as a result.

[@trev0rbr]

@@OliverFetter how much boost are you running and how do your egt's look? A Giles pump should be giving you plenty of fuel. If you run out of idle adjustment you can reindex the throttle lever on the throttle shaft. But I don't think that's your problem because the giles pump should be calibrated pretty well already.

[@OliverFetter]

@@trev0rbr Making about 25 psi & egt's w/o propane get up to ~700C on a long pull

[@trev0rbr]

@@OliverFetter ok where is your pump timed? And do you know the condition of the engine itself?

[@karicktrotter5871]

Hi new to your channel and looking to turbo my 1982 1.6 rabbit any suggestions for a good starter kit I also need an injection pump if you could recommend that as well thank you

[@OliverFetter]

Hello! There's really no kit - your best bet is finding a 1.6TD motor / acessories / scrap motor and combining it with a regular 1.6! It's a bit of a piecing together.

[@tiagonunes9422]

Had mine with Garret T3 @1.4B boost and injection at almost max and it was way quicker than 1.9TDI 110hp

[@OliverFetter]

That's dope!

[@jordonadkins4253]

Definitely upgrade to a TDI, get like a 1Z or something so you can reuse your mechanical pump. I'm thinking you can't use a 17mm shaft pump on a ALH but I'm not 100% sure.

[@trev0rbr]

You can use that shaft but it'd be easier to get a whole other pump because idi pumps are really different

[@nurburgflip1188]

alright i'm just barely looking into this whole deal. I have a tdi long block that needs to be rebuilt..out of a mk4. I also have a 1.5 diesel out of a 70's rabbit. So it's possible to use the injection pump on the tdi? Where can I find out more about this? Thanks.

[@joeyc2198]

Hey man I have a 81 rabbit with a 1.6td in it and I keep getting air in the fuel lines and I can’t figure out we’re it’s coming from. Have any recommendations on what to check ?

[@OliverFetter]

In which fuel lines specifically? Between the pump & the motor?

[@82DieselBunny]

I would never go back to that shop to dyno anything if they just “overlooked” your temp gauges pegged. Sounds like they are terrible.

[@OliverFetter]

Certainly a bit sloppy... in fairness, they usually do trucks.

[@VintageVaughnVehiclces]

Hi it's me again, I bought an audi fox coup somebody installed a 1.6 turbo quantum engine in stainless exhaust but everything else is stock. Got. My rock auto cart full of odds n ends. The used vw sarejust too expensive. Car is orange and I've got classic spectrum. Recaro seats and cloth for the back seat. Body has 123k miles Still has a factory brass radiator. Going to have to red kote the fueltank and have a set of snowflake wheels for it. The fun of a vw coup with those audi circles without the vintage vw cult following price. Those new orange 2022 audis are like 129 grand.

[@OliverFetter]

Sounds like a move!
