I thought I would do something fun and different. I did all the work but the machining. I built it for a circuit monster all im waiting on is the injectors and fuel pump. do you think it has potential?

B16 Block fresh hone stock bore
Crank ballanced to 11k and micro pollished
ACL race bearings
Ballanced rods with ARP bolts
JDM b16 pistons ballanced
Milled for clean up and single ply HG
PR3-3 head Ported, Valve job
Stock back cut valves
Supertech springs and valve seals
AP2 retainers
S2 Pro 1 cams
Jun Auto Tri-Y 2.5 collector
RS*R GT2 with no cat
Type R intake mani
Neptune on E85
Compression Around 11.5:1

Now I was thinking RC 750CC injectors?
and I dont know what TB?

What do you guy think? 200 whp?
Im open to all suggestions

Thank you guys!

 

180whp is my guess on a dynojet.

310cc injectors is plenty but it doesn't matter if you're using a tuning system.

 

I agree on the injectors, however I think 200whp is possible depending on how high you are willing to rev the engine. King Motorsports used to sell a B16 crate engine that had 200whp, except they were turning 9000 rpms to get that.

 

A S2 manifold w/ portmatched TB (66-68mm) might be a decent upgrade to look at, depends how much you want to spend. My guess would give you 8-10whp over the stock pieces.

 

Yeah I think that is what I am goin to do. Its the S2 Type R V2 so I think the opening is a 68mm but ill have to check. 00RedSIR 310cc on E85? wouldnt i max those out? I am just planning for the future cuz I have a C1 thats bored to 84mm that im working on after this is done.

 

really it comes down to the head work...it takes a pretty good port job and valve job to make those numbers out of 1,600cc

 

Why are you using stock cut valves in a P&P head with a valve job?

A 68mm TB would be great. I have seen the Victor X work very well on high revving B16As. 310-370cc injectors will do the job. Your setup is not 200 horse capable.

 

Stock valves= the best valves for all motor apps....unless you going oversized.

 

yup....oem valves outflow any aftermarket valve....the only valve that comes damn close is supertech.

 

good luck on your goal.
personally i think its a waste since its still only gonna make 125ft/lbs and unless its going in a very light chassis its just not going to feel that impressive. to each his own though.

 

And supertech has the highest failure rate too....so its a catch 22. Ill be using ferrea 6000's for my turbo setup

 

Stock valves will not out flow Ferrea valves!! Ferrea are better than stock and Supertech.

If you guys want to keep using stock Honda valves as opposed to a company like Ferrea (my choice) who has specialized in valve trains for many years and many engines then so be it.

To each their own. Cheers

 

And you sir are wrong... its been tested but the stock back-cut on the stock valves is better then any aftermarket valve available...and the overall fitment is just better.

Some of the fastest NA car builders on HT have input on the topic, so if you want to argue with them, have at it.

 

He's not running a King motorsports engine and he will not make power up to 9000 Rpm.

310cc injectors might be a little light for E85, so I would look at 440-550cc to be safe.

 

A while ago I saw where Ferrea was good for 12 CFM over a stock valve. That is what I am basing my opinion on.

In that thread, ALL MOTOR gained a few horses from switching to which valve??? Thats right FERREA!!

Not Supertech, not Skunk2, not Manley, etc.

..... and I DIDNT see any flow charts confirming your stance that stock are better than any after market valve.

Like I said...To Each Their Own.

 

call any of the big boys (ccc, portflow, alaniz, RLZ) who port heads for a living and ask them which valve flows the best oem every time
Better yet call Brad @ RLZ and ask him how badly oem valves outflow ferrea and the only valve that comes close thats aftermarket is made by supertech.

 

I did a lot of researchng and what I have come up with the oem valves and a Valve angles made alot of power. So thats why I kept my stock ones. I also based my build largely on omnimans and this one. http://www.utahhondas.net/index.php/topic,8917.0.html

 

I will do that. CC Cylinder Heads will be doing my head work. I will confirm it with them before I send my head off next month.

 

there is no way you gain 12cfm from switching valves unless the valve job was drastically different in which case the gain is not really from the valve per se.
even on a head already flowing 300 cfm that would be a 4% increase.

its good that you base your opinion on something you saw one time. This wasn't on the internet was it, those guys are dicks.
i think some of them are just on there to make money, too.

 

That thread is null / void.. power will be seen from swapping valves, is it worth the money? Probably not on a mostly stock build.. or a mild build.. but all out race builds its probably a good idea, people will have opinions, just like a *******, everyone's got one, doesn't mean its right.

 

valves are just one of those tricky components that real world differences are hard to compare, it gets to a point where numbers don't tell the whole story.
bottom line is for the majority of builds there are way more critical aspects than valve manufacturer.

 

Sorry bubba you are actually wrong on this, It has been proven by many pro racers that the stock valves are better than most anything out there in terms of flow

 

the first time the shop used ferrea valves in one of the 900whp+ motors a damn valve dropped first time on the dyno....all these years of using supertech and not one failure.

where do these idiots on honda tech come from? i would love to see some actual data to support your bs statement.

 

I get called an idiot daily on this forum for stating facts. Its pretty sweet. 2 of my buddies bent supertech valves, one mushroomed and one dropped his #1 cylinder intake side.... But im an idiot, they lied to me, those wernt supertech valves.

 

As previously stated, I was going off of information that I came across some time ago. I am NOT the type of guy who cannot be objective and who will not listen to reason.
For me, there is no shame in being wrong.
