No one can guess here. Seriously the only way to know would be to dyno tune it.

 

why the hell are you using 1000cc injectors with that setup? that's just dumb. it'll actually make less power with those, and will make the tuner's job a pain in the butt. it'll also make it run horribly inconsistently

also, you probably wont be able to use 93 octane on that setup, compression is too high. you'll more than likely need to use a 50/50 mix of 93/100, or pure 100 octane.

 

No, no, and umm no.

Using ID injectors alone would help, today's injector technology is far surperior then what it used to be. Spray patterns from ID, FIC and RDX injector types or the bosch EV14 types are just all around better. This isn't 1998 where we're talking about RC.

Bigger injectors aren't hard to tune at all.. if you know what you're doing.

You need to read up on ID injectors.. there's alot to understand about all these new injectors out.

 

It could make anywhere from 275whp to 280whp depending on a few things. Anything under 275whp would mean that something is up with your tuning is setup.

The twm itbs are not going to really give you significant gains if any over say a stock RBC or RRC. Reason is that the k24a needs bigger size ITBS in order to shine over a normal manifold. I do have to admit, they do look and sounds pretty amazing but the gain in power is simply not there. Maybe the midrange might be worth it for you though.

Good choice on the Private Label Mfg header. Sure its a replica but at least you are getting it from the source where most replicas come from. Frank and Kenny run a good business.

You probably know this already but the lighter flywheel will not really give you more power.

Running such big size ID injectors with 93 octane will be ok I guess and down the road you could always try E85 or race gas and see some gains but I am thinking that it is possible that you are going to probably loose some power with 93.

On most of the k24a engines that I did with 12.5 compression we just modified the honda OEM injectors to flow around 490-520 cc by removing a small metal disk that was restricting flow with a file. We were able to see beyond 300whp so I am thinking that maybe you injector duty cycle is going to be on the lazy side but you never know until you try it.

The potential for 300whp is there with this combination if you change some things around eventually but you are going to primarily be limited by your

-type of gas
-induction
-camshafts that are really not that aggressive for a k24a

Eventually once you get it where you want it to be maybe a custom header could pick up another 5-10whp if you were to switch to a megaphone type of header 4-1 if your purpose is to drag race it.

here's a graph from a similar engine I built and dynoed 5 years ago, time flies!




With variable cam timing and tuning with Kpro or AEM, you can get it running on 93 pretty reliably but make sure you get it tuned right and go from there. You could try asking your tuner to create 2 maps for pump gas and race gas if he has the time and patience to try both fuels. At high rpm, pump gas is not ideal so dont be surpised if your first runs you get only 250whp, its very possible but that is a solid start and a good base to start with. With TWM Itbs there are 2 ways to tune it. I would use some short of a vacuum box to be able to collect air from all throttles and then with the tune you will take an average to get it running decently.

Be careful when driving on open road with the ITBS because its possible to get something sucked in your engine that could lead to the death of your engine. It happened to my friend once with his ITBs and k24a. He was outside doing some datalogging where all at once everything shut off. Later after we opened up the engine we found some small rock that caused the valves to go boom etc etc

best of luck with your engine and hopefully you will get it to run close to your goal.

You didnt post about this but hopefully you are going to run a k20a2 oil pump because the stock k24a oil pump is heavy and not the best at high RPM

 

Preach on!! My I.D 1000's are at 50% duty cycle and idle better than stock.

 

i'm at 12.5:1 on pump 91

 

did you get it tuned yet? What is it making?

 

never mind, I found your dynosheet you posted on another thread.
