The torque curve is crazy wide! Must be pretty great to drive in most any gear!

Just because I am curious how boost builds up, do you have any data on boost levels vs rpm?

Seems like your break-in tune was at 8-10 psi and 240 hp. With the extra 8-10 psi and nice 3" exhaust, I would have assumed more whp per psi.

The dyno does look like above about 4,500-5,000 there is something choking it a bit. At 18psi I wouldn't think the log manifold is the issue. I see others say they have gotten a fair amount more whp on the log manifold as well. I would think you could pick up some hp with a better manifold and downtube at the same boost level you are at, but doubt the log manifold is the main choke on higher rpm whp.

Have you seen any other F22 or F23s running the same turbo at similar boost levels? Seems like most of the ones I have seen have an AR of 0.57, or 0.63.

It seems hard for me to think that intercooler is the hold up at these hp levels, but I may be wrong. For the money I would think a larger intercooler couldn't hurt though.

I can't remember, do you have a cam or a different intake manifold? Both stock parts are very restrictive

I have a Bisimoto 1.2 cam and a stock intake manifold. From what I researched though, the stock F23 manifold should've been more than sufficient. I always heard the F22, although very similar, were pretty much good for what I was shooting for. A guy a few years ago, AFAccord, made 417hp on the stock manifold and only bored out the TB and had it plenum matched.

Hello Honda-Tech world. Been awhile since I've posted. Just out of curiosity, what synthetic oil is everyone running. It's been about 1000 miles since my last oil change so I'd like to do one soon and with only about 2000 miles on the new engine, I'm thinking of switching it up. I used Castrol Syntec 50W-20 faithfully since I bought the car 13 years ago with 53K miles on it up until rebuilding the engine at 188K miles and never had issues. Considering now the engine is built and I'm running boost, I know the right oil is quite important to the health and longevity of the internals. The first oil change I did after my "break in" period was Pennzoil Platinum 5W-20 however after a quite a bit of research on the topic, I've heard really good things about the Pennzoil Ultra Platinum line as well as the Shell Rotella T6 5W-40. Can I get everyone's thoughts on their oil choices? Thanks in advance.

In for this as well. Im currently on Honda genuine full synthetic 10w-30 because it was actually cheaper then the local auto parts store and I figured Honda wouldn't use crap oil.

Ive been recommended rotella by my tuner but have not made the switch quite yet waiting until my oil needs to be changed.

hello! pls send calibration!
thanks!

So I just got my first oil analysis back from Blackstone and aside from them putting down the wrong engine type, it appears things look pretty good and healthy in my engine which only has about 2500 since the rebuild. Oil was changed at ~1200 miles and was Pennzoil Platinum 5W30. If anyone can chime in with their opinions, I'd appreciate any insight.

I would get a bigger turbo because at this rate, that engine will last you over 20+ years...

Just wondering... How did this build go ? Thanks ..

Good. Finished up about a year ago! Have only put maybe 2000 miles on it since. Still running great. Had to change out a few things, upgraded radiator fan, small things here and there. So far so good! Still a pleasure to drive.
