David Vizard talked about nitrous helping turbos back in 1979.. He used it as a way of reducing lag on a turboed Ford 2.0 Pinto engine.

Mr Richard, it would be interesting to see the use of nitrous on small quantities, early on the powerband to assist spooling the turbo. And also it’s benefits on lowering the charge temperatures and allowing more timing. This is a very effective practice when we run rotary motors with large turbos. Rotaries have no low end torque, so we obtain it with the nitrous, but in order to “match” the flow of the engine at high rpm you need what typicaly would be considered “giant turbo” per cubic inches. As an example, i run a peripheral port 20b (2.0) with a 110mm turbo and a 250 shot. Now, the nitrous is “reverse progressive” you could say. We will launch it at 175-250(depending on the track), it will progress to the “max” @ 250 and immediately start tapering in relation to the boost but no less then 75hp. During testing, we found a lot of power up top with the small shot due to the cooling effect mainly, and it allows a bit more timing.

Richard out here giving us the information we all need for future LS builds!

For those of us that have tried to tune a boosted setup ourselves, I wonder if adding nitrous is just asking for it. Engines make tons of power with boost and nitrous, until hey don't. : )

I have literally been waiting on this video! Everybody says oh you don't need nitrous with new turbos they spool faster than old ones.

My bro used to run a 50 shot of nitrous just to get on the chip , once he left the line no nitrous was used . ( it was a big single supra and a turbo 400)

Merry Christmas Richard to you and your family! Thank you for gaming us up always!

Hi Richard, also, very informative on how manual boost controller has the peaks and then dips for boost VS a electronic boost controller boost curve more consistent table top across rpm band! I never knew that! Also will be great to see a follow up video showing a electronic boost controller! Also even how to plumb and wire and electronic boost controller ! Thanks Richard!

Awesomeness. I’ve always wondered about this. I love how you move through all the data promptly. Keep up the good work bud. 👍

We ended up running a 100 shot on blown Gen 3 Hemi with a Magnasun supercharger as chemical intercooling, was good for 9.1's and much more effective than it's integral intercooler. Holley HP management, dry shot.

I don't mind running a little richer on the nitrous. Any time I've got a single fogger setup I always get concerned about cylinder to cylinder fuel distribution from the fogger nozzle. If it were direct port, no issues, or if we were adding the additional fuel through the injectors. But unless I'm running EGT sensors on each cylinder (or preferably O2 sensors), single fogger setups will always be richer on my watch.

Wanna see truck Norris with a turbo

They love the nitrous. If you dont put the waste gates right on the bend after the manifolds...put them on a straighter part of the pipe and little at angle..the boost wont jump around like that...its hitting the gates hard with them right on that turn. Cool vid. Keep em coming!

Ahhhhhh, more cowbell 😁. That seems like a really good test combo. And then the spray 🤘🏻🇺🇸

When you going to do this for an old school motor like a 383 or 355?.. good information as always

Richard da best

Lets see that controller test bro!!! 💪😜

The 706 head is the best factory head ever!

Interesting the N2O boost curve mirrors the N/A boost curve.

RH you the GURU

turbosmart electronic wastgate is the cat's meow

I would be worried about mixture distribution (fuel separation) with that intake manifold and a wet N2O system, and would convert to a dry system with the supplemental fuel added by the EFI in the nitrous table.

I'd like to see a turbo ran at it's full potential and then sprayed a 50 to 100 shot

Nice So Tuning is key

Nature's little speed bumps

What would happen if you used a standalone fuel cell for the nitrous enrichment 🎯

Free Sub Contractor Drinks are Triples Unless Stated Otherwise. Juice+Boost+bottle on Full Throttle

This relatively large turbo seemed to come up in boost pretty early making me think it had a tight turbine AR. I’m wondering if that made the back pressure run higher. If so, could you substitute a bigger AR turbo, like a 1.3 T6 S475 or S480, and use modulated nitrous to get it going early in the rpm range? This would seem to give both good spool up performance and relatively low back pressure at the top. Time for another set of tests!

Could you achieve similar results with an electronic waste gate by slamming the motor with boost instead of nitrous? Would the response be compar... Oh you're doing just that now!😀

Awesome video!!! Can you turn it all the way up and then spray it?

Is it Boost O'clock yet? 😁

What about using a progressive nitrous controller off the hit with a ramp in would that mitigate turbo lag?

Do you have any tests using say a 50 shot at 2000-3000RPM to spool a large turbo more quickly?

rich we need l86 content

Needed this info

I have a question I have a 6.0 built with a gt45 turbo I bought a high volume oil pump from melling did I buy the wrong one? I think I need stock volume high pressure or am I wrong

👍💪

Be neat to see you run it pre-turbo and see the difference. With and without the IC.

If the boost pressure went up with the nitrous, but the engine ran fatter... Is it possible the nitrous adds mass flow rate to the system and there's less flow at the mouth of the turbo? Is this running on an open-loop fuel table?

Those dam squirrels

What about a 6.0 with a pte7675 and the turbo is maxed out choking at 700-800whp, would nitrous help make more power or would it make back pressure worse?

Richard I have been following you for years! I think I’ve seen every one of your videos, which are great! But I think your putting a lot of confidence into the people watching your videos! I don’t know if you’ve seen any of Joe Simpsons videos from Tempest tuning! He gets tons of builds in like what you see on KZfaq! ( Not just yours either, one of the famous guys who’s cam you tested) & other Low Dollar builds! That are a complete pile of shit 💩! Most people think that because they saw it done that way on the dyno, it’s perfect to run down the road or track that way 🙄🙄🙄🙄! People actually think 🤔 you can just spaghetti shitpile your wiring together & just shove a nitrous nozzle in a rubber & there good to go! I understand it’s just for dyno testing, because we have done it ourselves tons of times! Just watch a couple of his dyno videos! Especially Camaro & Foxbodys, he ends up spending hours & hours just to try to make it into the building for FCK sake! He has refused to take a lot of them! Telling them to take them home & have them rewired, fix the falling apart driveline, fix the shit falling off the car! Then people seem to just bring them back with basically nothing fixed, over & over again 🙄🙄🙄🙄🤯🤯🤯🤯! I think I would mention, just because you think you can, doesn’t mean you should! I would hate to see all this great stuff go away, by someone getting killed or hurting someone else because there nowhere’s near being a mechanic, & really shouldn’t be anywhere near a fast car! Then you hear, but those internet guys did it that way! Just a observation! Because we are starting to see the same garbage in our area! Luckily the shops in my area are busy with legit, correctly built stuff, & they refuse it! But then we start hearing, oh those guys are assholes, because they wouldn’t dyno my car! See where I’m going? I hope I didn’t offend you! Thanks for the great info!

Ill bet he blames squirrels.

Do you use stock bottom or I need to forged something

I am curious what the intake charge temps with & without the NO2.

Delete that procharger A2W intercooler and run the test again??? por favor . :)

I can see that ring gap from across the room lol

What's a bottle of nitrous cost

Ding ding ding winner winner chicken dinner lol

What's the inlet temp

Now do a turbo way too big for the 5.3 and use NOS to help spin the turbo🤣🤣🤣

Nitrous is for kids. You need to start running pure Oxygen injection!

Personally I blame squirrels

Mmmm, squirrels, the other white meat.

Wait wouldn’t 11/1 af at wot be on the lean side with e85?
