Turbo exhaust housing testing | fullBOOST

While it’s common to upgrade the size of a turbocharger for more horsepower, a sometimes overlooked aspect is the rear side, being the turbocharger exhaust housing. In this video we’ll take a look at a simple exhaust side upgrade and see what real world results it produced.
The car in question is a 1980s Holden VL Calais featuring the factory fitted Nissan RB30 turbo engine.
The turbo used in this dyno session is the Garrett GTX3582R Gen II tuned by Ben D’Annello of D’Annello Performance and is being run up on Tunnel Vision’s 3000hp Mainline hub dyno.

Love videos like these that show you the dyno data on the same day under the same conditions then follow it up with real world testing. Love your work.

[@calaisvl2]

Listen u won’t believe me but that actually is my dads car and thanks for the kindness btw if u don’t believe me look at my profile

[@diaspo]

Shout out to whoever set up that suspension. She sat absolutely rock solid on those runs.

[@Russell_and_Rosko]

It’s a hub dyno

I never thought about taking the same snail and putting a different shell on it. Thanks.

I had a GT35 strapped to the side of my dead stock motored VR V6 (manger lol) Commodore wagon a few years ago. Running only 14psi (was limited by the 2 bar map sensor) I couldn't run any faster than a 12.1 with the 0.82 housing the turbo came with. Swapped it out with a 1.06 housing and first pass went 11.98, eventually ending up with an 11.74 changing nothing but the housing. Tune and everything else was the same. Obviously response is slightly sacrificed but with a decent converter I hardly noticed it. Does show that exhaust housing sizing is important and even though my car was 2 seconds slower than this VL, I still saw a similar improvement (yes I know 0.4sec faster on a high 9sec car is a much bigger gain than on a high 11sec car, but you get the picture :)

[@Rexy888]

Great video but yous need to do more hektic voice overs to gain more rwkw.

[@xd_boudi-_-2563]

That’s me dads car now the VL is way better and faster

[@MartinMcMartin]

I always enjoy your in depth looks at these cars.

[@brianrichards782]

Very nice car very nice power and supporting mods you can tell the difference between a car that's made for the forums and KZbin power numbers vs a car that's had everything upgraded to keep balance

[@i_am_tinny_man_2267]

very interesting comparison, we have been playing with the same turbo but modified by procharge turbochargers in Melbourne but on a Barra, so far made 580rwkw on about 25psi and went 9.6 with the t4 rear 1.16, as happened to this vl we have dropped boost significantly from the factory ford t3 (also ran 9.6) and now need more spring in the gate to get boost up to 30 psi or hopefully more!

[@freesexyew]

[@usa5046]

[@manitoublack]

for a drag car the lag tradeoff is almost always worth the loss in transient response. For a street, circuit, rally or hill climb car. The choice is rarely that simple, where transient conditions play a much larger roll.

[@aftastosk6016]

For street use even a 0.82 a/r housing is too big for a GTX3582 installed in a 3 Lt engine.

[@ianharrd]

nice car mate!😜💪 What catch can is that id love one form my build 👍 Also what strut top covers are they id like them as well 👍

[@bilko6169]

Maybe upgrade the wolf ecu??

[@bioshock425]

Quick one. That hybrid manifold is doing some work. Would you see an increase of horsepower if had better flowing manifold. Ie 6boost, sinco.. But killer build.

[@dannthenitroman]

Is the runner diameter too small for 115hp/cylinder or is the collector design poor?

[@bioshock425]

@@dannthenitroman well the collector is not as good as a 6boost. Hybrid are just a affordable manifold if people on a budget. Maybe runner length is a tad better on a 6boost... would be a good test tho. M

How much did the boat go down just by fitting the bigger housing?

[@7071t6]

Fantastic stuff, just wish someone would post a stock VL Turbo factory stuff to see with basic aftermarket items like exhaust and blow off valve and exhaust system and tune stock injectors and running on E85 or 98, just to see basically what the cops had back then?

[@fullnoyz7670]

Cop cars were stock turbo engines running 150kw engines

[@honestlybrutalvlt9762]

What the actual fcuk. Wanna see stock cars? Subscribe to top gear.

[@3800TURBO]

I did heaps of stocker jobs back as far as when they were new. A dead stock VL turbo will do around 130-140rwkw. With a decent intercooler and around 14psi from the stock huffer they will turn 185-200rwkw depending on the exaust on it. Then its up from there depending on what else you do. E85 will add at least another 30% power depending on the combo. Would run out of stock turbo around 220 odd.

[@sexyfacenation]

E85 didn’t exist back then, bov does nothing for performance, cops had nothing special

[@nightrider50105]

Please I need an upgrade for my V6 Camaro Rs 2010 .. k&N Intake and tuned I need twin turbo or supercharger kit from you guys I’m from KSA I like Aussie modifications and cool stuff I also been there in Melbourne a couple years! how much can you offer me ?!?!?! The total price

Actually PDrivetv did a test with a factory turbo with exhaust and intercooler at 8PSI and then 13 PSI with around 150 KW approx, still quick considering most cars just had over 120 KW at the engine at that time here's the link.

[@cava454]

How delayed was this video? Those drag races were 12months ago.

[@NightKnight1776]

640hp. for an RB30 is absolutely extremely low. thats like daily driving setup. an rb30 can handle well over 60+ psi assuming its the diesel bottom end. so at this point your held down by either fuel or turbo.

[@fullboost]

The owner's goal was to run a 9.

[@NightKnight1776]

@@fullboost nothin wrong with that. i respect that. im just curious if the owner wants to really pump those numbers up. and it wouldnt cause any damage (as you know rb30s are absolute monsters)

[@fullboost]

It's all a trade off though, you keep moving the power band it gets less driveable.

[@NightKnight1776]

@@fullboost i agree. That engine at 600 would last forever.

Not quite.

Scotty over at SM could make this power with his green top gas motors ;)

It didn't run a 8sec pass.. that rb30 wouldn't be worth 2k. Hahaha.

[@honestlybrutalvlt9762]

Yea good on ya Barry!! If it wasn’t for vl turbos you would never have a Barra turbo. Took yous 30 years to realise your na motors are absolutely embarrassing so you took holdens idea from 30yrs ago and revamped it with modern technology!! Only reason I support Barra is because it’s a modern version of our iconic vl turbo. Just a shame they (fords) are that disgusting to look at.
