I keep getting IMs on this, and hence decided to post.

Bisimoto level 2 street cam on F22B1 Vtec in a 1994 Accord with intake, cheap header, and 204,382 miles on the odometer. Baseline versus untuned level 2 installed:

Those are some very impressive results.
Whats the price on that bad boy?
And are you able to tune that with a VAFCII the recieve similar results?

GhostAccord

Nice numbers.

I'm really just learning to read curves and I'm wondering what causes the big tq dip @ 3900-4000 RPM? I can see it on both the stock and untuned level 2 runs but it's more around the 35-3600 range and it's not quite as pronounced.

Turbowa

I would assume that is because of the vtec engaging. Great results non the less. You should be able to tune it with the vafc-II but you prob. won't see the gain's that are had from the AEM-EMS or a hondata S300.

TurboWA is correct! Thanks, sir!

GhostAccord

Cool thanks.
I won't have to keep an eye out for that then

is this aggressive enough to need to have up graded springs and retainers?

DCFIVER

As powerful as most stock H22's. Thats good ****.

It depends. If your staying NA then no, but if your going forced induction then yes.

this makes me want to run my sohc into the ground with style and alittle more pep for the mean time.

what up with the stage 3 cam 94 non vtec f22?
idle friendly?
stock valve springs?

0Bisimoto

Level 3 is almost a track cam. Stock springs are a no-no, as our pro springs are required ($159). You will need some sort of engine management system with it as well. Extremely lopey idle. If idle quality is important to you, opt for our level 2.

the level 1.2 turbo cams for f22b1 do u think they would be safe for a 75 shot tuned, my car has 200k miles on it but compression check was perfect across the board my nitrous is a little fun while im saving up for turbo kit.

I have a bisimoto cam in my motor, not a stage 2 but some FI application cam he worked up some time ago. Next cam will be another bisimoto for sure if I go bigger.



No back to back results here with and without since too many other things changed at the same time. I can say however though that these cams peform for sure. I make power to 7200 on quite a bit of boost.

hb_guy

bisi, do you have any turbo cams available now? if so how much and any dyno#'s

very impressive as always man!

AFAccord

Glad you posted these Bisi. I assume it's recommended to replace other components as well, but are valve springs the only component required to be replaced for the level 3 cam? Would it even be reasonable to consider a level 3 if I don't plan on reving past 7k?

Always curious why not set vtec back around ~2400rpm where it is stock, to smooth out the power band so there's not that dip?

Turbowa

vtec doesn't engage at 2500rpm stock. If it were set that low you would engage it just driving around and when cruising on the freeway. You have to have vtec engage where its going to be the smoothest transition. Remember once you start to modify you car it will never run, idle, or have the same power band that it did when stock.


With the level 3 your going to def. want to go above 7k rpm other wise you won't get its full potential. Side note the more aggressive of cam the high up you power band is going to be shifted.

And AFAccord read bisi's whole post, spring and engine management. Something along the lines of AEM-EMS or hondata S300. The v-afc or any other piggy back won't work to well you will need a full stand alone.

AFAccord

Thanks for the response.

Actually, VTEC engages ~2300rpm at high-load, atleast on the F23's and I'm certain it's similar for most F22's since they're not the high performance oriented VTEC designs found in the H22, F20B/C, and B-series. So yes, it does engage just driving around town, and almost always when cruising on the freeway.

You answered my question about the cam. My bottom end is stock for now, and I've heard enough horror stories about F23's reving past 7k and suffering from oil starvation that I don't plan on going past that for reliability concerns. My tuner has my stock cam set at -4 degrees to move the power band up, placing me at 169whp/164wtq right now (OBD1 P61 tuned on eCtune, VTEC set at 2350rpm), which is what brings me to this thread. If it's true that a level 3 cam won't make peak power before 7k, then that's what I need to know.

It's nice to see sohc's making good power. Torque curve on the last one is .

are you familiar with the design behind the f series sohc vtec? when you look deeper into it there are good reasons for it to operate when driving around town. as an aside it engages between 2300 and 3200 depending on MAP.

Whats Up DOHC

Here's the thread for the last dyno on cb7t:

http://cb7tuner.com/vbb/showthread.php?t=105737

Keep in mind he has an H23 intake manifold which is good for quite a bit of power throughout the band;

However,

He made the same power as another dude w/a mildly ported H23 IM, Delta 272, Kamikaze header and 2.5" exhaust and a full tune- without a tune... so this cam, combined with an H23 IM, Blacktraxx IAB spacer/delete, header, exhaust, BPI flow stack and a good tune would def. come close to what most stock H22s put down

On 87 gas & 8.8 CR

A long standing question over at CB7t is, 'should I build an F22 or just get the H swap'

I think this cam is a push for the first option for sure. F22A w/high comp pistons, head w/all the goodies & I/H/E will at the very minimum give a stock H a run for the money

I'm hoping to get this cam down the line.

Since I started looking into rebuilding my car 2-3 years ago. I looked around to see what people where doing. At the time it was all about spending $2K+ on a stock H swap. I have always felt that dollar for dollar the F could be a better platform. Bisi's R&D into the world of the big block SOHC F22 gave me that added push to go for a SOHC F22. At the time the prices for F parts was up there. But still not as much when you compared them to doing a stock H22 swap for an extra 45hp.

Def.

My F23 build pulled four car lengths on another H22 swapped 6th gen from a dig up to 80mph.

Whats Up DOHC

I want to build an F22A head on an F23 block... 9.8:1 compression and 2256cc FTW!!! H22s won't know what hit them...

HATCHBACK GORILLA!

WOW....very nice gains all around!... I cant wait to have a set of cams/ cam gears for my GSR swap to finally finish my build!!!!
