ITBs are generally known more for their throttle response and sound instead of big power. That being said, the “wall” at 8000 could be due to a multitude of things, from the head package (cams, ports, chambers), to exhaust pairings or primary sizes. My guess is you guys need a biger cam with more duration for the flow requirements of the ITBs. EDIT: Going back to the engine build video, the cams used are the Drag Cartel 003.2 cams, and the dyno chart on their website shows peak at 8000 RPM. The Hoonigan Skunk2 K24 10K RPM build used Skunk2 Ultra 2 camshafts. (EDIT2) The drag 003.2 specs: Intake: 13.8 mm Lift / 254 Duration @ .050 Exhaust: 13.2 mm Lift / 250 Duration @ .050 The S2 Ultra 2 specs: Intake - Lift: .560"/ Duration 270° @ 1mm Exhaust - Lift: .535"/ Duration 270° @ 1mm Thats a big difference in duration 254/250 vs 270/270… (EDIT3) Corrected the Skunk2 duration @ 1mm lift (EDIT 4) Converted cam specs for @dooby1445 to show I’m not a caveman: The drag 003.2 specs: Intake: 13.8 mm Lift / 254 Duration @ 1.27mm Exhaust: 13.2 mm Lift / 250 Duration @ 1.27mm The S2 Ultra 2 specs: Intake - Lift: 14.224mm / Duration 270° @ 1mm Exhaust - Lift: 13.589mm / Duration 270° @ 1mm

Just to restate what was already said in the video: we're not super impressed with the power the car made, but making horsepower on small, NA engines is all about finding the perfect recipe for flow. Nothing on the exhaust side has been optimized yet, and we have a lot of brains to pick in the all-motor ITB community about what the best combo is for power. Here, we just wanted to get the car running and driving. Can't wait to revisit the dyno with more of a game plan to make power.

with the ITB's you need to look at pulse timing between the exhaust and intake, you may find playing with trumpet lengths as well as ex primary lengths may where your extra power will be hidden, it might be worth putting a single throttle manifold with longer runners to see what it does to the power.... these are things i have played with when converting to ITB's because they generally dont make the power initially you think they will....you have to find it

the resonance length of the ITBs needs to be tuned in sync with the cam duration at a certain RPM where you want to peak; you want the pulse generated by the valves shutting to bounce back and fourth in the ITBs and return just before the next close of the valve. Ideally less bounces (longest possible pipes) gives you more of the effect.

Its worth adjusting the intake runner length for sure- But hed be chasing a single digit for HP here. He more than likely is just being limited by his cams. Theyre drag cartels "street" cams with only 254/250 duration. Theyre mild aimed at meaking peak power by 8k rpms.

@chippyjohn1 Most ITB kits far cars are limited by packaging, and so are shorter than they should be. In order to not hit the shock tower or require a hole in the hood, ITBs for the K usually have super short runners like a sport bike. Most tests I've seen of trumpet length favor the longest ones you can possibly fit. The ITB kit for NC Miatas uses curved trumpets facing forward, something like 2 feet of length from.the valve to the trumpet end, and that kit makes 225bhp at 7,500 with pretty minimal non-VTEC cams. Ben's ITBs are less than half that length, which says to me that they want like 14,000rpm. Obviously the cams and the exhaust will have gone to sleep long before that ever happens. But the point is, all this stuff is dependent on resonance and timing. An engine like this has to be treated like a 2-stroke. Bulk flow is secondary to resonance timing. The exhaust and the intake must match the RPM target, and the cams must not get in their way. Most importantly, you have to at least know what you're working with in terms of length and resonance timing. Simplistic ideas like "good" or "big" have little value at 10k rpm.

Hmm, I think they need to do some basic engine maths (inlet velocity, exhaust velocity and the way that's matched to the cam profiles etc) before just trying random parts! The maths (or math in American English) will show guidelines of the cam profile required, inlet runner diameter and length, exhaust runner diameter and length etc required, before then dialling it more precisely with trial and error on the dyno. No race team would try to design an engine without doing the maths on it. 🙂

Well this is what happens when you throw shit on a wall to see what sticks. There is no engineering behind this build. Obviously you need to tune both the ITB setup (diameters and runner lengths) to the camshaft specifications, head flow and have an exhaust system that is tuned for your goals. You cant just throw stuff on it and see what works. There are probably multiple foundational errors in the setup that need to be fixed mathematically. It is not about what fuel you use or what oil you have, if the intake and exhaust pulses are not in tune with the rpm you aim for all it doesnt make any sense. But I am a huge fan of the concept so I hope youll get it sorted.

Meanwhile, I'm just starting on my TRD front strut brace for my GR86 and hoping that adds the rigidity up front that I'm looking for since So Cal roads aren't getting any better, and I swear roads are wearing out faster because EVs are already heavy and SUVs/trucks dominate the market. This S2000 build is something I would do with lottery money.

Weird man, my buddy built a all motor same engine with itb’s, in his garage on his spare time, when we brang it to the dyno it made around 240-250 whp but that was first trip he said he has to figure some stuff out and go back for more power! Maybe it’s his cams not sure!

Making power with that is harder than making power in even an ancient b series. Is it the head flow? What else could it be?
I was wondering whether a stock port head would hold them back with cams and ITBs when they first put it on. I'm not an expert or anything, but the only advantage ITBs have is massive flow. If you're running them on a stock head, it doesn't seem worth it.

@@samnolte749 Unfortunately with all motor you have to do alot of work to the head and have non restrictive valves, and you need alot of compression. I wouldnt have even used Itbs, they just suck for street use. I would have went with minimum 13:5 compression. Most likely if I was going all in it would be 14.5:1 to 15:1. above that its very nock sensetive even on ethanol.

More cam duration for the higher rpms. Short ITBs for high rpms. Do a compression test to check your numbers. Make sure the plugs and spark is strong.

Awesome it revs to 10K, I just want my 1.8T to Rev to 8500, but it definitely doesn't make sense to spend that much for only 200hp. My 1.8T is around 280 whp (factory rated 170 crank) and it's unopened with 200K miles. I'm not done with it either. Big turbo and rebuild when I get time. All I still need is valve springs.

Try playing with the ITB trumpet length and cam timing. I know shorter trumpets typically resonate better at higher RPM, but you gotta just play with everything, everything you change changes the resonant frequency of everything. NA is a trial and error tuning process, i mean Garage-4AGE can attest to that. Check out his adventures in NA power if you want, he's getting 220hp out of a 1.6. Try shorter trumpets, longer trumpets, advancing the cam timing, and pulling it back, and every compbination of those you can. Try changing when VTEC comes in to help tune out that dip.

Do you think its the runner length of the ITB's?....shorter ones normally give power higher up the range but sacrifice torque. I personally think it can't be that because its too much of a power loss but its one of the only things I can think of. Are the cams capable of flowing at 10k?

Pro Tip: 40% ethanol provides a VE bump above all other concentrations of ethanol. So if you don't need more octane, e40 is the best ratio for an NA build.

octane peaks at e50 anyway. e40-e60 is more than fine for most every car out there.

There are plenty of ways to build just for insane power numbers. When I had my B18C1 swapped Civic, I obviously wanted power but the joy I found was in light weight and lots of revs. I didn’t get into seriously wild setups, but I rebuilt the block with higher compression and she revved to 9000, made peak somewhere around 8300. That car wasn’t about making 400 HP, but she weighed less than she did stock (even with several hundred extra pounds with the swap), and she revved and made amazing noises. If I ever did it again, I’d go for that kind of setup over tons of power. And I really respect what Ben is doing here for the same reasons.

The biggest dictator of the powerband is the camshafts. Other factors of course are exhaust and intake flow too but the cams are the problem. It doesn’t even sound healthy either imo. Watching the engine build video, Ron wasn’t able to address what parts would be required to run those rpm. Or it was omitted for other reasons, idk. Sub par engine builder, having your own machining capabilities don’t mean jack when you can’t identify the correct parts to make a hp goal at a specific rpm range.

I honestly think you need a different head. If I remember well you got a k20z3 head. Uprated springs and cams but no headwork. If you spent so much money on the build, just get a 4piston head to suit your build, and I am positive you will pick up a huge amount of power. Also as other people have mentioned, just find out what sort of trumpets you need in terms of lenght to match your build. One lenght can make power whereas other can give you 0 HP. Best of luck!
