im trying to increase my red-line and im not having much success, i have valve springs and retainers, do i need upgraded valves too? with kteller their camshaft is 290 but does anyone know how much the core charge is...and finally I've searched and haven't found anything but i was wondering what the difference between peak and hold injectors and saturated injectors? and what size i should be looking for for a f22b1 ~ thanks

 

Why would you want to increase your redline? The f22 doesn't make power up high anyways. BTW, the rev limiter is set in the ECU.

 

The reason that car made so much power was because it had a turbo. You won't gain any power by increasing your redline. And like I said, you will need to retune the ecu due to the revs being limited.

the car wasnt turbo it was na and the rev limiter is the fuel cut-off which is at 7k

 

I R Tylor's giving you good information and you keep blowing him off. You might get your head out of your *** and try listening.

 

I call BS on that. Give us proof.

 

July edition 05 of sport compact car..there's about a 4 Page article on the f22a1 (accord dx) engine and i have started to build my engine off of this. the engine im talking about is used in the honda insight drag car

I guarantee it wasn't na. And what the expletive do you think cuts the fuel? A magical hobbit in the crankcase? Just throwing on bigger injectors won't do anything but make your car not run.

Edit: it's not supposed to say expletive, it's supposed to say fu(k.

 

this is the car i have been talking about http://www.battleoftheimports....t.htm
and i apologize if i pissed anyone off but when i know im right and im told otherwise it pisses me off

 

There is no way in the world an f22ai is making anywhere near 300hp.
But sure buddy put the biggest freakin injectors in you can find! If A fully built N/A B16 strains to make over 230 there is no way a single cam is going to make that without forced induction.

 

this is not the exact article that i was talking about the one i read was much more detailed but this is the car and the engine that I've been following for years.

 

1. Take a black marker and paint over the red line on the tach. Voila, higher redline.

2. If you have a 5spd, the only thing stopping you from revving higher is the rev limiter. And yes, rev limiter = fuel cut. Guess what...? It's ECU controlled.

3. Power will fall off very quickly after the stock rev limit. If someone is making more power after that, it's because they have internal mods. It's not simply a higher rev limit. Notice how your peak power of 138 whp is at 5800 rpms? Think about that for a minute...

4. I would not raise your redline without completely redoing the internals anyway. The bottom end is going to destroy itself at higher rpms, and rather quickly at that.

5. Stock rev limiter is not 7000rpms. More like 6500, while the redline is 6250. If your tach reads higher, it's inaccurate.

6. Simple truth is, you're not listening to the people who know what they are talking about. N/A 300whp F22 with out internal mods? Show me.

 

I see, you are talking about bisi's car.
#1 No NA f22 making that kind of power has any street drivability.
#2 That's a f22ax, which is a better engine than the f22bx.
#3 Building a NA f22 is not cost effective. Plus bisi's is carbed, and the secret to it's power (one of many) is his carb tuning.

Finally and to the point, raising your rev limiter will net you absolutely no gains. Your engine makes no power at that rpm. And you can throw any multitude of parts you want at your car, but it still won't rev past 7k. It's that damn hobbit, cutting your fuel.

I concede, you were right, that F22 was NA. My mistake.

 

found the guy and his car on honda-tech
https://honda-tech.com/zero...age=1

"bisimoto" he also had a 9 second crx that had a f22 na motor

 

Do you know how many mods (and money) were put into Bisi's motor? And that's not exactly a "streetable" motor either.

 

i understand its not cost effective, and im not trying to make 300 whp im aiming at 200 max so it is drivable, all i wanted to know as some ppl have said on here is that replacement for displacement is a high red line and technology, all i wanted to know is if i would get much of a power gain if i upgraded my drive train and valve train ( camshaft, camgear, springs, retainers, valves)

 

yea i understand it was about a $15,000+ engine but im not looking to make a drag car

 

To get 200 whp out of a f22 is no small, inexpensive feat. To get anywhere near that, you need to build the bottom end. You will need high compression pistons and extensive headwork. To my knowledge there are no off the shelf cams for f22's, so you will need a regrind. All that will require tuning, and probably slightly larger injectors. It has already been said what you need to do to raise your rev limit safely. Also, you are sohc, so a cam gear is useless.

Bisi's website: http://www.bisimoto.com/

 

why couldnt you have said that in the first place..i understand its expensive and i also know im going to have to change timing and the compression ratio. i wanted to know what larger injector valves and a cam regrind from kteller would do..i already have their retainers and springs.

 

Why would he have said that? You didn't ask about that...

I'm not trying to be mean... I'm just showing you that all you asked about was raising the redline. Anyway... Best of luck in your build.

 

lol i have that problem of thinking things but not typing them..my apologize its been an incredibly long night after replacing both front calipers and pads and re-surfacing my rotors and fixing my exhaust

 

Haha, it's okay man. We all get that way sometimes.

If anyone paid attention to my set up..it is very simple, unlike the other low 10 to 9 second twin cam racers, with tons of money, engine management, alcohol, and tranny work.

I guarantee you that of all the sub 10 sec race cars, mine is the most cost effective.

Yes, I am a cheapskate: I even retain my stock glass on both the Insight and CRX, and ran 12 on the street with a D16 on pump gas.

Accord vs. prelude/b-series: Pistons cost the same, for all street applications. Cams are cheaper, valvetrain is cheaper, headwork costs the same, and you do not need an aftermarket crank.

I wish many of you REALLY knew me: I hate to part with money, and that was the initial allure to SOHC technology.

Hmm. The engine is a sohc configuration. so an adjustable cam gear is useless??? Based on????

Well said. Bisi, why does it seem like everyone on honda-tech knows just SOOOO much about your program and has all the answers? Extremely funny. I guess its the same reason people tell us we can't run carbs on the street cuz they aren't streetable daily??? Or how sohc is a waste of time and is never cost effective?

Honda-Tech(?) at its best.

 

I think you missed what I am saying. I am saying building a NA F22, especially f22bx is not cost effective. I stand by that statement.

Adjustable cam gears are used primarily for adjusting valve overlap, which can't be done on a sohc configuration. He can still advance/retard his cam timing so I suppose it's not entirely useless.

Bisimoto:
I really admire what you have done with the f-series, and am in no way saying anything negative about your setup. However, Accords way nearly 1000 pounds more than a CRX at stock. I am simply saying for a daily driven Accord turbo is a better option than a NA f22. You can hit 300 HP without cracking the block open, and have torque to match.
