As many new cars are high 11s and with slicks now 10s and 9s. 12 for na is so awesome ad gives me hope Ty appreciate the content

Oh hey man thank you for checkin’ this out And notice the on-board? I always give Jasper a hard time for Granny shifting and a slow granny at that 😂 But he trying to preserve his tranny so can’t blame the dude 😂 But we know shifting a lil quicker might cut better time as the quicker shift to 2nd would and could lessen the 2nd gear spin so there should be more Which I think it’s something u could get too sooner than later man

Gotta love the good ol B-Series!

[@SRDmotorsports]

Oh fo sho!!!!!

[@kmvguy]

Thanks for that dome info. I’m planning on running them for my street/autox build. Aiming for less than 12:1 CR for 93 octane here to be safe.

[@SRDmotorsports]

Bruh!! Thank you! And yeah for street/autoX build I think the Gen1 YCP will be def hard to beat the mid dome level is like an ITR will def be efficient for 93oct for you… man with the right parts that be a beast!!!

[@kmvguy]

@@SRDmotorsports No, thank you. Do you have any experience running a thicker cometic head gasket? I’m currently planning on using .051 thickness because i have around .011 decked between my head/block. That puts me around 11.7 or 11.8 according to the zeal calculator depending on the piston dome cc. Well.. maybe around 11.8-11.9 because I also have supertech flat valves.

[@SRDmotorsports]

@@kmvguy wait up on Tuesday I’m trying to prep a vid for this Autocross d16 we did will talk about cam choices related to intake manifold choices 😎 I havnt tried thicker cometic gasket but Cometic has always been good in my book… I think it will do no harm if u run a thicker one that restores the “lost” deck from milling previously on the head/block surfaces I think this is the rare moment that Cometic lets us go back to factory spec mill level

Oh my man!!! Thank you for noticing and thank you for being here man! will try harder for better content some more :)

[@timm5970]

you tapered the weights on the crank to slice the oil in the pan easier?

[@SRDmotorsports]

Not totally taper but the surface refinish, polished to increase “oil shedding” Which in turn lessens oil cling on the rotating mass of a crank Good eye man!

[@timm5970]

@@SRDmotorsports It definitely looks polished but tapered as well. Can you make a sharp edge on the weight or will it remove too much material to keep the engine balanced? If the edge is sharp then in theory there should be less resistance when splashing into the oil making it easier to rev and increase horsepower? Never even thought of this stuff before lol

[@SRDmotorsports]

@@timm5970 good thoughts right there and yeah there is enough material to shape it indeed Just quite time consuming 😂 On mine I didn’t do this cuz wasn’t willing to spend “extra”’on balancing Funny on how we sometimes (often) cheap out on personal stuff lol But since Jasper here was willing to have it dynamically balanced I figured it’s atleast harmless to do this :) but possibilities are better

[@miguelmoreird16]

Hey, Ralph, first of all congrats for the videos, great work. I wanted to ask you and all the people here on this "circle" . I have a b20b 84.5 bore with p30 pistons stock rods, b16a2 head ,ferrea flat valves supertech valve train, arp bolts on head and rods, compression is around 13.1:1 but I run a mix of 98 octane and methanol, around 10%... Now my question for you guys is, how far should I run the rev limiter... I don't run drag races, most mountain roads. 82, 84 hundred? Thanks 👊

[@SRDmotorsports]

Fodas! How did u know my name lol But yeah sounds like a healthy engine set up… Because u are on arp rod bolts 9k is safe I mean u can go 9.5k but I prefer 9k because u mention “mountain roads” Those long turns can be too fun :) that repeating it often is “correct” lol!

[@miguelmoreird16]

Forgot to say pro 1 cams Obrigado, I will try to keep it lower than 9k, but will see what the dyno says too! Thanks a lot , keep pumping those videos! 👊

[@SRDmotorsports]

@@miguelmoreird16 yes pro1 is excellent so u got meat of the power 8500 so yes sir 8.8k might be good

[@kmvguy]

Hey, I have a question. According to this video, you said that the YCP are USDM spec type R pistons. Why did you calculate them @3.2cc instead of the 3.64cc (suggested on zeal website)?

[@SRDmotorsports]

I personally measured and cc’d the dome and got 3.2cc

[@kmvguy]

@@SRDmotorsports ah I see. that makes sense. I couldn’t find this info anywhere else. Thank you

[@SRDmotorsports]

@@kmvguy I mean it’s okay the 0.44cc volume diff is small… just its what we got on the gen1 ycp so we reference that hehe

[@xbseries7443]

Can you test the new 84mm ycp version 3 pistons ? Its deadmatch copy of the arias high dome pistons.

[@SRDmotorsports]

Not sure but the 1Up was the first deadmatch copy of an arias 7.4cc dome I know cuz I knew where the “piston” cam from and Al =‘owner of franksmotorsports is a personal friend Hehehehe

@@frivera735 the CTR they call but for a b20 ? That I’m not sure 🤔

[@juansuarez185]

Did they upgrade the rods when upgrading to 1 up pistons or still stock rods?

[@SRDmotorsports]

I built that stil same stock rods

[@findtherightbeat]

2:42 are those markings on the "R" piston for gas ports? ;)

[@SRDmotorsports]

Ahhh good eye that’s the YCP gen1 Yes marking = if you know me… you know every moment the piston is resting and waiting to be assembled on the work bench = ideas come So I was spotting up areas where I felt gas ports would be good and wanted to asses where it sits if too close the valve pocket “eyebrows” which could lead to cracking Dayum! good eye man!

[@findtherightbeat]

@@SRDmotorsports Did you end up running gas ports on the YCPs? I remember Belben did those on P73s back in the day too, although some of the other experienced guys advised him that the cast pistons are too brittle for it.

[@SRDmotorsports]

@@findtherightbeat actually no I havnt and it wasn’t my engine that’s why so I was iffy on the “brittleness” of cast but I’d try it on mine if I could but rather than have a machineshop do it? I’d get a drill press for it Major downside is… stability is had only as the drill press gets bigger and the bigger it gets the price gets exponentially larger loool so expensive FTL But maybe soon

[@findtherightbeat]

@@SRDmotorsports True that! Belben's edge was that he was a machinist by trade and had his own machine shop.

[@findtherightbeat]

@@SRDmotorsports Hope you can do a series on the below: • Pressure recovery in the port, chamber, and seat area • Vortex and vortices that affect flow and combustion quality • Understanding the angle cuts on the 3-angle valve job • vena contracta • valve and the valve seat's influence on flow -- low, mid and high lift

[@juanmaldonado7204]

Hey nice videos!. I’m currently building a b20 vtec for the street. Supertech full head, ported head, stock rods and I’m still unsure on the pistons and compression. What would you recommend for the street and on pump gas?

[@SRDmotorsports]

Oh nice , YCP and 1Up pistons will be a good choice

[@nicopotgieter453]

Hi Friend, very impressive, thank you for sharing. I Follow you . What was the exit speed for the Honda with the 12sec runs, and what diff ratio(GEARBOX)do you use for the 12sec pump gas street car? What is your octane rating(RON) in your country? 😊🙏

[@SRDmotorsports]

The exit speed is around 176kph I compute because it’s in miles… gearbox is a 4.4final drive TypeR transmission so it’s also LSD Octane is also RON here it’s 97ron

[@nicopotgieter453]

Thanks for the reply, keep on doing what you doing. Your doing great work

Thank you! The tires are also 24inch tall so a little taller than normal tires so it could affect the exit speed but I believe not ALOT thank you also for checking the video :)

De-burred sharp edges on the crank counterweights?

Great eye! Actually smoothed then polished all the crank counterweights before sending off to dynamic balancing = goal was to have “less oil cling” As we know we can balance the crank but oil clinging will always be random every millisecond So some details we do when we know we would dynamically rebalance the crank But rare u need to dynamically balance a Honda crank they’re always well balanced from the factory
