LET'S TALK TWIN TURBOS

TURBO TALK-DIY TWIN TURBO KIT ON A 4.8L LS. Q&A SESSION

[@correygoffney7054]

Who cares about idle this dude has done more engine tests this week alone than anyone else on the tube.

[@jgadventures6409]

Hes forgot more than ill ever even know lol

[@bobmotherfuckinsmith3089]

One might say Rich has been Holdener down.

[@turboboy-oq6xe]

Lol

[@prestigeracingmotorsports9169]

Best I’ve seen for Richard

[@niknasstie]

Finally stock manifold vs long tubes. Rear mount set up vs front piped to the back. Real testing that needs done!

[@pierredentremont2999]

I watch all your videos! Love your testing of all the engines.

[@richardholdener1727]

Glad you like them!

[@jt5782]

Yes PLEASE do the Mercedes M113/kompressor, would be quite interesting to see how far they can go!

[@tnsd5801]

Mercedes pre-Chrysler partnership is pretty solid. Post-Chrysler has been junk and worse. Cracked pistons, balance shaft separation,.....the list goes on. The Best or.....WETF we can charge a premium for!

[@haydenstorm7517]

Air cooled VW engines would be cool to see tested and modified. There is a lot of people building them for dune buggies and even drag racing.

[@joshmajors5963]

That's the exact setup I have been wanting to see. Thanks Richard

[@corvettefever360]

Yeah do to my work schedule, I rarely catch anything on U tube live, but always catch up the next day or a couple days later

[@tonykomer2997]

Running water inj before the turbo WILL pit the compressor wheel blades. This is all stuff learned in truck diesels from the 1990s early 2k. Think about those wheel blades spinning at 100,000-120,000 rpms hitting those droplets repeatedly. The issue with uneven water meth distribution per cyl I s because of the lower psi of the water meth pump. In true race setups for water inj on pulling truck or drag turbo diesels large pressure washer electric motors are use giving 1500-2000 psi nozzle pressure vs 75-150 psi you get from those cheap weak tiny motors on the snow systems. The issue is the dropplets have affinity for each other and join creating larger droplets and go to the cyl based on their runner flow effiency. If you look at individual cyl psi and individual egt you will see thus effect. Try running a cheap chinese electric pressure washer pump setu0s mobile car detailer find popular. They run about 1500 psi and are like $100. Run a power inverter to plug it in or for dyno use wall outlet. Set a jet at each intake runner equal distance from head intake port. You will see a HUGE difference. You need less water meth but at the same time can use more. Its all because of many times better atomization. Water dropplet size is far less for better mixture. The down side is the pumps are loud but ideal for race setups. Many d8esel setups with compounds will run a intercooler off the atmosphere / low psi turbo and then run water inj post high psi turbo as the final charge cooling. Again the reason for this is the water dropplets if run thru the turbo compressor will over times Everly pit tge compresor wheel blades. So for an all out race compound setup for tractor pull let's say is gtx55R intake to air /air or air water IC. Exit into GTX4294 intake. Out to intake plenum. The intake plenum with water jet nozzles over each head intake port. Nozzles connected to 1.5K electric pressure washer pump/motor. Setup off a boost referenced regulator. Just consider what the cyl psi and egt or AFR per cyl is with carburetor setups running what 14 psi thru the carb jets!?! SNOW Water inj is 10x high psi. Inj water at the TB if you want more even distribution without increasing inj pressure you need to run much higher meth concentration. Gasoline turns into vapor at much lower pressure vs H2O. Meth is very similar to gasoline in this area. But water needs 10x the jet nozzle psi to get decent atomization if you are looking for the intake to distribute evenly. The fix is to 0ut jnozzle jet at each intake runner. But ideally you still will do much better with higher psi.

[@blow0me]

Using a 5 bar works perfectly fine, and allows you headroom for safety cuts etc. Never max out a max sensor.

[@LukeSportsman]

I liked the turbo comparo video You've made the cheap turbos legit. But have compared a "name brand" to equally spec'd budget turbo? Say a Xonda Garrett or Precision to the VSR or X brand?

[@Rourkeize]

You need to get a hold of some Mercedes M113 4.3/5.0 and 5.4 amg. All aluminium and the internals are forged from factory. Would be interesting to see turbocharged with rings gapped :)

[@MB-ib5ji]

I was looking for a movie to watch and then I noticed this is basically an hour and 30 minutes long! so put on my pajamas made some popcorn and here we go....

[@mikestufano4961]

Ritchard I have a cool Nissan 4.0 you. An have for the dyno. They are built bad ass with the mains not having bearing caps as they have a huge girdle that holds the crank. Reminds me of what they do to the olds and big block Pontiac’s to keep from splitting the blocks. This 4.0 Nissan motor looks like it will take a ton of boost and stay together. I run 33 lbs in my Snomobile and I like the Nissan motor and kept it to see how much it will take. YOU CAN SO IT RITCHARD!!!!’!!! Big Bang Nissan motor ! If you want it you got it. It needs a little Work but it isn’t cracked

[@JesusRamos-yy9iu]

Thanks for your time I really enjoy your advice and noledge iv always been a car guy always loved v8s absolutely love the sound om not exactly looking for speed I kinda grew out of going fast but yes om in love with my 99 Durango wish I could make it sound like a scat 392 my Durango has a 318 Om wondering can I get 427hp and torgue out of a 5.2 This going be my first build om currently looking for heads and cam for it lord can't wait to here the cam lobe I love this stuff reminds me of horsepower tv I really appreciate your time thank you very much ser

[@blow0me]

I'd like to see you test a range of air filters. Often in vehicles, people are heavily restricted for space, like myself, I've only a pair of 4" tall filters as have absolutely no room. SO would be good to see how much power is affected on singles or twins going from say no filter/volute, to large filters, to very tiny filters and even those zero filter guards.

[@rodneymalbrough2090]

Mr Rich #1, I’m absolutely love your videos and I appreciate the great work that you do. My question is and I may have missed it somewhere. Is it 100% mandatory to adjust the rings in your pistons before you put any turbo on? Can you truly take a 53 or a 5.7 out of the wrecking yard and slap a turbo on it, thank you

[@richardholdener1727]

You can run boost of junkyard motors-but added ring gap is a good idea since you don't know what the gap is and high mileage doesn't seem to change the gap much.

[@BJL2142]

I own a mb c200 Kompressor, if you ever get the chance to look inside one of there engine bays you will notice immediately how much room there is for a turbocharger, I want to run mine as a twin charged setup where the turbocharger pushes through the supercharger and I think the first place I will start is porting and polishing the factory supercharger and remove the stupid baffle that's designed to make them quiet

[@BULPIN847]

Totally stock 230,000 miles Chevy Silverado 4.8. I want to pull the ECM and the BCM out and put in a Holley HP and single turbo. No problem, big problem, probably put in a 5-speed to manual that would be a badass little truck then right eventually do full rebuild

[@alshotrodgarage4779]

The ford 6.2 sohc in the raptor is actually the base engine in the super dutys for the last 10 years so there are countless of them floating around

Have you made a vid comparing a single Gt45 vs twin Gt45 on a 5.3 or 6.0?

[@richardholdener1727]

twin gt45s just offer twice as much power but more lag-I did that test on a BBC-the vid is up

[@pedrorodriguez9265]

I'm putting a 4.8 gen 3 on my slingshot and do a twin turbo on what is the best top end to handle the boost

any top end will handle the boost-what is the desired power level

I'm wanted to get between 5 and 6 looking at the gt45 don't want something too cause of space in engine area

[@MrScottt28]

Love the twins!

[@MrLightning54]

On a supercharged Coyote F150, I'm running long-tube headers with converters. do you think adding boost referenced wastegates immediately up-stream of the cats would help keep them from being destroyed? I've heard of converters collapsing, and taking engines out soon after in boosted applications. I don't have enough room to really have priority flow placement of the waste-gates, it would have to be nearly perpendicular to exhaust flow.

[@davidbettencourt6014]

How would twin gt-45 turbos work on bbc 454 90s block peanut port heads higher compression pistons and cammed

[@mikerounds1907]

When you compare the twins vs single can you make sure you add the data for the single turbo with the closest back pressure?

[@user-by1io4fq3j]

What turbos did you use for 1600 horsepower

[@richardholdener1727]

I've never run anything that made 1600 hp, the 1543-hp Big Bang 6.0L used twin S475 T4s, but those can support another 400-500 hp

Twin 'ebay' GT45's VS S475 or other large single turbo. Looking for around pump gas 1000 H.P. 5.3L cast truck engine (will eventually be doing a 383 stroker on a 5.3L if a 5.3 can't do it below 7,000rpm-7100rpm ). It would be great to achieve 1000 H.P. closer to 6000rpm for street/strip application.

1000 HP ON PUMP GAS IS HARD
