I think some engine builders start watching SRD videos… and while watching he begin to understand the reason why the last project he did with his customers blew up….. :) shoutout to all the engine builders watching on srd channel now

[@SRDmotorsports]

i agree i sense alot watch it and we can see on fb posts cuz if it wasnt cuz they watched it here? like a person who said (not a friend) said "bakit ngayon lng" on their posts if they werent watching this lol

[@CL9k24a3]

Eye opening stuff that you share here. People would argue to death that high comp would make more power.

[@SRDmotorsports]

oh man! in my country too!!! hahaha "high comp" is lyf 🤣 i didnt get to include (forgot to mention) the 148whp was on 95octane pump but the 147 with less torque was on 110AvGas

[@tylerortiz7197]

Love the channel Please keep making video like this !!! 🙌🏼🙌🏼

[@SRDmotorsports]

Thanks man! and honestly it is fun for me I get to share tidbits thats often not in a topic of convo online or elsewhere like the runner length calculations or cam measurements

[@4077661466jp]

So you basically did a surface clean up rather then porting ? I always thought porting involved material removed to gain pathway/runner shape to valve desired= increasing cfm flow, has surface clean up alone made a difference ?

[@SRDmotorsports]

If you have seen a stock d16a6 u would see this isn’t just a surface clean up but overall shape has been reworked… “Porting” have always meant different to different people However a max cfm 320cfm B16 head won’t perform any better than a cleaned up B16 head on a “b16” maybe it would shine on a 2liter especially a stroker… port volume is often over looked… and some castings already have alot of it while some are a little under volume so it needs work

[@mikodelacruz]

Single cam content! WHOO

[@SRDmotorsports]

its my "relapse" moment of addiction cuz my current d16a6 is already assembled and running 😢 so the spare head is available to be shared on this video but hopefully more sohc stuff soon!

What is the ideal length of the itb to make the great power

[@SRDmotorsports]

Actually for the 2nd harmonic sadly it won’t fit our firewall so I actually just run the longest safest with the stacks not getting too near the firewall I believe it’s 9-10in ITB runner length

[@BenjieCoB20VTEC]

Great content

[@SRDmotorsports]

thanks man! hopefully the tidbit about runner length catches the tech savvy peeps interest... still having a hard time figuring out a good spring content man but trying, though I figured a "valvejob" "multi-angle" type of content might be interesting too as locally we both know just like the reason i made the "assembly lube" video cuz they all give a vague answer (locally) "kelangan ito" lol

[@kerbieprince7894]

Good job 👍..

[@SRDmotorsports]

thanks man glad you enjoy

[@jdeworks7034]

KEEP THE D SERIES RUNNING :) THE CAMSHAFT IM USING ON MY RACE CAR WAS ALSO MADE BY WEBCAMS ITS A CUSTOM GRIND, JUST LIKE YOURE'S I NEED TO MAKE ROOM FOR THE CAM A LITTLE BIT OF GRINDING ON THE CAM TUBE AND AT THE BACK OF THE EXHAUST ROCKER. THEY CAN MAKE WHAT EVER CAM PROFILE YOU NEED BUT FOR ME THE LIMITING FACTOR IS COIL BINDING SO I GO FOR THE MAX LIFT THAT IS SAFE FOR MY SPRING AND FOCUS ON THE DURATION. IM JUST A NEWBIE ON ENGINE BUILDING, IF YOU CAN ADVICE ME SIR ON MY ISSUE I WILL GLADLY APPRECIATE IT :) THANKS...

@@jdeworks7034 ah yes yes 0.35mm is the closest safe... you can bring ur head to ATi they can machine tri-angle ur exhaust but you request them to sink it 0.5mm sinking it means the lash side? goes higher so more space for coil bind :)

Wowowow sohc build 😍

[@SRDmotorsports]

Thats my current powerplant... Thing is, the reason I always mention those "stuff" intermittently on a few videos is cuz I finished building my d16a6 merely months before I made this channel like just "months" so now im like "what coulda been" 🤣 a personal build series. A blessing in disguise perhaps cuz this time atleast its gonna get constant "updates" be it commercial or preview will always share it here

[@midnightkaiju]

@@SRDmotorsports looking forward for more videos chief. After watching this video, i'm back to square one thinking should i let go of my sohc or should i go with the one i mentioned to you for a difference. 😂🤣

[@SRDmotorsports]

@@midnightkaiju hahaha thats the thing that always happens, much the same when it comes to my personal stuff lol

[@jspecricer2734]

A complete stock b16a, it would benefit to port the head

[@SRDmotorsports]

If ported and done properly i believe it would. It can give better throttle response and fuel economy to boot! But crux of the matter : the b16a pr3 head is almost near over in port volume for a 1600cc so careful portwork on the b16 head is needed or else too much porting means a b20 block is needed for more displacement hope that makes sense

[@peterbryant3584]

Ok ok nice

[@SRDmotorsports]

Hopefully it makes power but I wanna pull down “my” engine and do a build series mainly cuz I will for sure “dyno” it

[@peterbryant3584]

That's confused me compressions thing head it 😳

head is milled and the piston has high dome , in shooting for the highest I’ve tried, so I experiment on my own toys :) not customers 😎
