REAR mount turbo ~ CULPRIT Torana

[@tonywebbywebb5019]

Update ! 7.81 at 177 MPH - 3250 pound street car

[@tonywebbywebb5019]

Thanks for the positive comments guys, we have no run 8.24 at 175mph

[@rogerpearson9081]

A few pros and cons with rear mount but the extra plumbing gives the intercooler a bit of help and definitely keeps the heat out of the engine bay. Would also be easier to work on. Different but it works.

[@DaveHiggoHiggins]

easily one of my favourite cars doing the rounds now. congrats to the owner and the guys team around it.

[@SPACE-in6tm]

Great build was a pleasure to watch, cant believe there's so many haters and dislikes? bloody weirdos.

[@mark52111]

Very cool car! I was not aware of rear mount turbo setups until now. Thanks for sharing.

[@Waltorious_Garage]

Not usually my cup of tea but I'm very impressed! Nice to see how well spoken the owner is too...

[@davidjohnson8474]

I frigging love it!! It sounds like a Jet car going down the track! Awesome job! We have a bunch of these rear turbo cars in the states

[@TriniRogue]

i've got this habbit that i upvote everything you guys upload, havent regretted a thumbs up to you guys yet :D

[@nokithecat]

Rear Turbo really keeps the heat manageable

[@Sherlz10]

never new a set up like this actually existed till now that's for sharing I learnt something today gives me an idea for my rx7 am building

[@spiro5327]

Love this car as not only is it quick but it still sports factory paint trim badges etc. The ultimate street machine

[@truthseeker8483]

Very well engineered! Love the sunvisor and orignal brown paint..a real retiree's car....rear mounted turbos are a great idea.

[@joshvhsle05]

cant believe how much ground this torrie covers so quickly. holy shit, what a weapon

[@turbostyler]

I remember seeing this thing cruising the streets one day and I just knew it by the way it sounded it was a bit special. Awesome little rig!

[@jimbodee4043]

Awesome build, great performance from sleeper like car. Parachute and giant tyres give a clue on drag strip.

[@flavourboss]

Cool as shit, I fucken love the RACQ badge, visor and paint work aye. The thing is absolutely stellar.

[@ThePaulv12]

Lag is a function of turbine and compressor mass not distance from the motor since a rise in a pressure vessel at one point = a simultaneous rise at all points iirc.

[@fullboost]

Well said.

[@goguhu]

Air does not move instantaneously, and nor does exhausts. Increase the distance from the piston (in/out) and you add time for exhaust to build pressure, spin the turbo, and air to move back to the intake. Yes, the mass (size) of the turbo does also add lag, but air movement/distance is the main cause of lag. This is also why newer engines put the turbo in the 'V' to get it closer to in/out, to lower the lag.

[@ThePaulv12]

No you're wrong: en.wikipedia.org/wiki/Pascal's_law

[@edism]

Mate you can't just make shit up. That is not how it works.

[@goguhu]

ThePaulv12 That's for in compressible fluids (AKA liquids), under 'reasonable' compression (excluding neutron stars here), however a gas (air) is VERY compressible ... something like 1000:1, while water is next to uncompressed (< 0.01%). Good example for this is wind ... wind just don't appear around the planet in an instant, it start somewhere, and then progresses, same with sound waves. And that's actually how quick a compression can move through a material (in compressible materials have a much higher speed, 10x or more than air).

[@subarolla]

Going down that track like a dream. Grip and go. No bouncing around and shite.

[@ryanrohauer5940]

if he bounced or wheelied bye bye turbo haha

[@Kaydencool2013]

You're never late in a 308 has never been so true. Seriously quick car

[@mazvxr1550]

Just found this. Totally sick build. Lovin' it. Need more stuff like this in UK. Sweeeeeet!!!!

[@Witness27]

I wonder if our generally wet weather would be an issue for it.

[@markemm8862]

Oliver Thompson - Yates Well i drive a VXR8 now so I'll put up with anything annoying it wants to throw at me :-) You only live once, live on the edge & enjoy it to the max...

[@jon...6825]

Wow!!! What a quick car. Good luck with you're car. Jon

[@markheffernan6695]

What a Brilliant little sleeper

[@AmariLambo]

Just makes sense you would be using a massive intercooler anyway with front turbo, and rear mount helps put weight towards the back

[@cinesoundasia]

Love this. What a great car,great dood. Forget the haters.Miss my Torana.

[@fullboost]

Tony Webb of Culprit racing shows us his X275 Holden LJ. The street driven Torana runs consistent 8-second passes thanks to a turbocharged Holden 355ci V8 engine that features a rear mounted turbo setup. The car has so far fared extremely well in the X275 radial APSA drag racing class.

[@vgannon-7303]

+Fullboost The look from the rear is absolutely great ! Really cool car.

[@griffsrearmountturbothemod1623]

Thanks for doing a segment on this set up. Nice to see im not the only one.

[@griffsrearmountturbothemod1623]

You guys should come down to Tassie do a feature on my rearmount monaro circuit machine on a club day. Theres a few nice old school cars in the club as well. Just saying...

[@squirts1]

the music is too loud... it overpowers the interview.

[@jamespalmer9556]

Fullboost does the turbo suck or blow the air?

[@DIRTDIVER882]

man that sound it makes is so sweet. like a little brown fighter jet.👍👍👍👍

[@hopebear06]

Great interview. So casual. What a friggin' WEPUN!!!

[@Pull_It_Apart_Paul_Ham_CB]

one of the best stories i have watched

[@pjtruslow]

holy shit the top end power. what a comeback at the beginning.

[@tgafire87]

More people need to do rear mount. Bad ass!

[@greg0063]

I think remember this was a mod to the old Trans Ams and Camaros it was easier to remove the muffler and stick it there than try and stuff it under the hood.

[@quadrapodacone]

Such a great car! Thanks for sharing!

[@andrewrigg4905]

This just makes me happy !!! So cool.

[@randyneil6161]

that is a really nice car

[@YouNameItGaming]

all that tubing must add a ton of lag. however it looks like it makes the boost come in much smoother as the turbo steadily pressurize all that plumbing evident with how it just walks off the line but appears to make more and more power throughout the run. as a person who's always shunned the idea of a rear mounted system, I've been convinced that it actually works :-) that, and it might actually be better suited to people who like a more predictable delivery of power

[@dennisrobinson8008]

Richard Holdener dynod quite a few and it appears the curves are delayed by 1000 rpm or so but the rest of the curve is exactly the same as a front turbo, no midrange or top end losses.

[@ls1edit]

Beautiful piece of machinery

[@BrisBoom]

Got no lag but once it hits 3000 the turbo kicks in. Ok

[@fullboost]

No, he's saying the engine is strong and it runs hard by itself anyway, it's not like some 2ltr with a large turbo, waiting for boost

[@christopherhurley2570]

Realistically a 5L v8 doesn't spend much time under 3k RPM, I'm really glad their setup works so well I want to do a similar rear mount with a 5.7L magnum, do they have no intercooler? Just using the return charge air cooling under the car or did I miss that?

[@Steezypleasy]

+Christopher Hurley It looks like there is an intercooler. Check out how the intake manifold piping heads down towards the front bar and there is another pipe coming up the other side.

[@berzerkrobot]

Turbo lag and boost threshold are two completely different things. The turbo reaches boost at 3k, it has nothing to do with what turbo lag is.

[@mareksumguy1887]

When will people learn about boost threshold vs lag!!

[@Xynudu]

That's really something. Fastest 2250 I've ever seen.

[@madmaniacloony]

with all that pipework how can it have no lag at all, well done sir for defying physics

[@HUBBABUBBADOOPYDOOP]

Actually- "with all that pipe work" you can build in a tremendous amount of backpressure *_volume_*. Think of it as a capacitor for exhaust. Think about it.

[@madmaniacloony]

how though every time you lift surely it would all escape and youd have to build all that pressure in the large volume of piping again. please enlighten me

[@HUBBABUBBADOOPYDOOP]

GHOST I'm sure the actual creator of it would be happy to explain it to you. Why not ask Him? Hint: look closely at the blow off actuator...

[@madmaniacloony]

give me his number and i will lol and i thought it may have something to do with that but im no turbo yoda, also im guessing thats a pretty small turbo for a 5l v8 but still i find it hard to believe you can totally eliminate lag without a pretty radical solution

[@zmanmd1641]

Turbo lag is only apparent in transitions from small throttle to full throttle at low RPM. In drag racing, the throttle is floored with the trans-brake and rev limiter controlling the RPM somewhere between 2-4k. The turbo is making boost at that RPM, but not full boost. As the trans-brake is released, the rev limiter releases, triggering full fuel flow with a wide open throttle and boost already present. So a drag car would never experience lag at the track. If he floored it from idle, he would most definitely experience lag until boost makes it way to the intake in a couple of seconds. It just won't be so apparent due to the large engine's natural torque in a light weight car.

[@vincentcorralez4772]

Wow nice Intro (: I like the design off the FB logo as week

[@vincentcorralez4772]

Well*

[@HoweDoYouDo1999]

Now I know to look under the rear at all times. Just in case anyone has any funny ideas going on under there. 😂

[@rudya4970]

yes gentlemen, heat energy into mechanical... its not the "bloww" of exhaust gass that spins the turbo, but actually the expansion of eat... mind blown!

[@Gr8mate13]

Beautifully put together car well done to you all

[@BMRStudio]

This car is just perfect as is!

[@glentight]

fullboost should check out the rest of the shed. should hit webby up for a tour.

[@amyasseektruth8246]

Car built right.

[@Power_Tech_TV]

Thats one bad ass little car.

[@cxbra]

It seems like it would be laggy, but in actuality it all depends on intercooler piping diameter.. A FMIC with traditional turbo setup would probably use 3"+ intercooler piping (on say a street Evo, not this racecar), but with the rear mount he'd have to do smaller piping to reduce pressure drop and lag.. It might actually be a cooler intake-charge running a rear-mount setup too.. Hmmm?

[@joemac9997]

Just awesome car!! Love it 👍

[@ashleypope346]

Good to know you still run a muffler per turbo.....Going rear mount on a low grout home built 355.....

[@dronepilot260rc]

There's no lag when you brake boost. thats simple to understand.

[@colingenereux]

[@andrewwelk2732]

All the best wishes.. I hope all you're dream,s come true.. take care keep safe..

[@lerch122]

runs down the track nice

[@shyecjj]

Why not run a sealed pipe from the inducer sealed up into the trunk and make side vents on the trunk for intake? Would 100% protect the filter and turbo from outside debris and water etc.

[@shyecjj]

Also take in cooler air not coming off the ground plus easier because of no head wind.

[@austintyler7991]

Nice car. Good drag racing. "Are we having fun yet" ? Heck yea lol

[@Jesseboucher541]

It's so smooth

[@BIGGIEDEVIL]

Impressive to say the least

[@truthserum6377]

Awesome mate!

[@Blueknight1960]

I don't see the turbo placement as a problem for a drag car, but I see a big problem with the placement as a daily driver. Standing water when it rains, more dirt/dust and other road debris as the filter has no protection.

[@gooseknack]

Those filters don't have much protection under the bonnet either.. In rain, it all gets damp anyway... This must be successful, or it wouldn't be done!

[@kylemilford5968]

water mist is actually very beneficial to boosted engines, Almost all of my friends use water fogger systems with pump gas to reduce intake temperatures

[@nickmendez3707]

blueknight move the intake point then fuck it's not like it has to be there

[@rogerramjet5092]

Also acts as an octane booster. People install water/meth injection all the time, to run more boost on pump gas. Dirt and debris , is more realistic concern. Run a larger filter or put a 90 degree elbow to move it up out of the trash...

[@Blueknight1960]

Unco Casey Why you getting your panties all in a wad?

[@GTRBaconR34]

Grout filled block, but you can drive it as a daily? Doesn't it get stinking hot? Sweet Torana!

[@finney67]

nice motor i would want a laminated screen wont be nice vacuming all that out

[@randiricci5620]

I wouldnt suspect there would be much turbo lag....since the rear mounted turbo is installed on a high horsepower motor & a short wheelbase subcompact Holden...ykmv!!

[@HueGWang]

Need this on my L98 (LS2+) VE ute. Zippidy dooda!

[@frozenmouse76]

how do you oil a turbo all the way down the back ? is there any issues with the length ?

[@spankeyfish]

wonder if he's had any debris punch a hole in that air filter yet, it already had a ding in it

[@14jeffo]

really nice job, tuff as well done

[@SgtGunny-gz5hg]

wow never seen a rear setup like that before

[@Ziggy75gg]

Any idea on the rear gear ratio? I have a similar sized tire/wheel combo but I don't think I could 150+ with my gears.

[@groupbmotors]

ok so how about water getting into turbo induction on a wet day? i guess in straya it doesn't rain much?

[@wreck_ignition7847]

+ghettodeffender How is that differant than a through hood/grille mounted turbo? Most people don't drag race on rainy days anywhere in the world.

[@conradbarns-graham7833]

What a great little car, a real sleeper that would shock the shit out if so many people, impossible in the wet though

[@truthseeker8483]

Grout filled? You mean like Concrete??? I really like this car, rear turbos make a lot of sense, heaps better than having a 3ft high supercharger sticking out of the bonnet. Sounds like a jet getting ready for takeoff...

[@tommygooding2308]

What's the difference between engine mounted turbos and rear mounted turbos like on the vid? (Apart from room in the engine bay)

[@Cams250]

one is on the engine and one isn't. :o

[@tommygooding2308]

Cams250 ok but what does the rear mounted one achieve? Why not just put it in the engine bay

[@tommygooding2308]

mr Powell wow, thanks!

[@michael2nicolaisen]

Turbo lag or not it's still less efficient with a turbo mounted a long way from the engine as the exhaust gases cools down on the way to the turbo and therefore has less volume to drive the turbo.

[@RickyD1968]

Thats Awesome!!!

[@cammmmm1234]

I realised that there were mufflers between the turbo and the manifold, would that effect the airflow into the turbine of the turbo??

[@griffsrearmountturbothemod1623]

Doesn't seem too affect the setup at all. A nice flowing muffler is the go.

[@RadostinVelchev]

What happens with the air filter mounted so low then you have heavy rain?

[@thecombatwombat833]

i wouldnt drive it lol xD
