How to Destroy a $10k RB26 Cylinder Head in 10 Seconds

[@josephmatuszak3855]

I could jibber with your engine builder all day long. I miss being a dyno tech and builder full time.

[@RyanLitteral]

He’s a great dude with a ton of passion for the RB. Love getting to dig into his thoughts and processes!

[@GTRPSI]

A little tip, i did a similar setup with 1/2" 625 head studs on a RB26 head, i also was a little sceptical that i had enough clearance around the head stud that the oil travels up around. In my case i ran a boost doc electric oil pump through the oil feed near the oil filter boss, left the rocker covers off and pressurized the whole system while checking oil flow out around the cam journal to verify i had enough clearance before sealing off the cam covers.

[@RyanLitteral]

Yea it is definitely a step that won’t be missed upon assembly/start up ever again.

[@mitchreviews5291]

This knowledge was awesome between this builder and Mike essa I’ve learned a lot

[@RyanLitteral]

Both of them have a ton of useful information and have been around for a long time! Love both of them!

[@josephmatuszak3855]

As for the heads, yes, bery much the same problem with the stock blocks and the bore spacing, the ports are not perfectly cast. If you CNC the entire port you are risking some thin spots.

[@RyanLitteral]

100 percent. I’ve experienced that SO much over the years. The way that Dsport does it is the right way.

[@signal_msw]

Always good to know people that know how to fix the shit that's hard to fix! Good to see and hear this thing ripping. PRP's cast iron block is gonna solve all your problems. No more growing and dropping oil pressure. You can always sell that billet block to some drag race guy. Also, as a note, friction does not equal wear. You can have more friction and less wear, and vice versa. Just something to add to your guys' conversation about friction and heat and such. One of the many weird properties of engine oil and its many additives.

[@RyanLitteral]

Yeah man it’s very hard to find people who are well versed enough who understand all of the complexities with running an engine like this. We’ve actually learned even more since this video has dropped and I’ll dig deeper into it on another video in correlation of the pressure drop. The billet block I feel is fine and I’m a big fan of the weight savings and cooling properties of the aluminum.

[@signal_msw]

@@RyanLitteral Very cool, looking forward to hearing about it!

[@jcas055]

@@RyanLitterallook for people from Ireland or Australia. There are people who know how to run and build these motors that have taken championships and done really good in battles

[@RyanLitteral]

@jcas055 so I’ve worked with builders overseas - from Australia and that sounds better on paper than it actually is. There are too many variables logistically for that to really work here stateside or any other country you’re operating out of. It’s best to find a builder local to you (or within the confines of your country) to ensure you can get things done and taken care of in a timely manner. It’s racing, timelines are short and things do happen. I’m just grateful I have good resources that are willing to do what it takes to make things right and want to succeed as much as we do.

[@jcas055]

@@RyanLitteral great to know that knowledge was sought for outside of the states but couldn’t agree more with what you said. It’s racing and when you need a part you gotta get it quick and in a timely manner. Having a shop in the states that can build rbs for big power and doing what it takes to make the motor run is optimal. I really hope this refreshed motor will give you the power, speed and reliability that you guys are looking for!!

[@undefined_garage]

Man it’s crazy to see your program you’ve been looking good this year in FD Ryan car sounds killer your knowledge is amazing for someone whos on pen and paper a driver. Sucks im blocked on IG cause im sure I miss a lot but im still here! Whats nice is you probably get these guys secrets they won’t share with us but with you they will! Thats key to growth and you’ve been growing you can see it which is why you don’t have the same issues you continue to find NEW issues be proud of that because that means your getting somewhere when you finally get “bored” and chill at a power or driver or whatever level you’ll be so satisfied because you did that 🤘🏻🙌🏻

[@RyanLitteral]

I really appreciate you noticing the growth within myself and the program man and your response is spot on. I’m proud to have the knowledge I have now and the people around me that have made me better. On paper totally just a driver and I still try and stay in that lane as much as possible but facing these issues on the mechanical side of things has improved my driving ten fold. I don’t recall blocking you but I’ll check my list and if it’s the same name as you have here I’ll unblock it. Thank you for reaching out 🙏🏻

[@GTRliffe]

always look for through the oil cap on first start up on every build. if you dont see oil appear after five secs of runing, shut her down

[@shaun54]

A PRP cast iron RB block could be a great option for you Ryan

[@jasonveto2320]

Did my man just make a bloodhound gang reference when they were talking about head ports?

[@vaughnjohnson5484]

🗣️ Lets gooooo!! Also, we do love car.

[@RyanLitteral]

Love you!

[@Skerplord]

As great as RB can be its not the motor to give back to you. No matter what you do shits still gunna fail at some point. Arguably best sounding fun motor. You'd have to re-engineer the wheel for that bitch to be reliable. Glad you got it figured out tho.

[@Boost-EdAutomotive]

Another great video 🤙

[@RyanLitteral]

Thank you 🙏🏻

[@themajesticmanic]

I mean, that is definitely the largest Hex Key I've ever seen....

[@RyanLitteral]

Right!?

[@feelgoodhorizon4084]

Did potting that Deutsch connector fix your dbw issues from before? Car sounds mean!

[@RyanLitteral]

It’s necessary to do but the real solve was better PID loop dialing and a software updates that negate the faults.

[@thisguycalledalex]

I took a minute with a litre of oil in the sumo. so. Good job 😂

[@GTRliffe]

why are there two exhaust gas pressure tubes?

[@Tyschnei]

Hey man! Ill be at FD NJ, any chance of a ride along at probrodown?

[@RyanLitteral]

Might be possible!

[@slow6six620]

Whats the difference between wpc? And shot peening? Isnt it the same?

It’s lit

It’s litt 😎🔥

[@josephmatuszak3855]

I'll bet you never dry fire a fresh engine again before verifying oil galleys are flowing and free. RB require the "old ways" of building and attention to detail. Every change requires a 3-Way consequence check.

[@RyanLitteral]

That’s not accurate of what we did. We did prime the engine prior to firing, as we always do, that’s why I have a primer on the remote filter housing. We just didn’t know that oil supply was choked off due to the head studs. We for damn sure checked after the other head went on and the studs were turned down and the head stud bores were also enlarged.

[@josephmatuszak3855]

@@RyanLitteral No offense meant. Just saying, RB are notorious for being... the hard girl to get as it were.

[@RyanLitteral]

Oh yea totally. Not being defensive just being accurate of what happened. These engines definitely require attention to detail.

[@mingscustoms]

What is the Uber3 blower used for near the oil pan?

[@RyanLitteral]

That’s used to cool down the alternator and clutch

[@mycool5281]

Alex should build your motor

[@RyanLitteral]

Alex?

[@blindabinda1234]

25:00 that seems like a horrible design

[@RyanLitteral]

Going to a 625 1/2” ?

[@blindabinda1234]

​@@RyanLitteralNo just the oiling to the head. You'd think it would have it's own dedicated galley

[@jaygood87]

I hate to say it but maybe it's time to change engine and go for something a bit more reliable? I would love to see you at fd and be able to run a full event/season without problems

[@RyanLitteral]

Did you watch the last two events?

[@sentientdogma1206]

A whole lot of yapping with not a lot of information given. Whoever was talking about the cam just loves talking for the sake of talking without actually delivering any meaningful data.
