I will not bad mouth your "master" mechanics that you've friendlied up to. Some of them can be great and have a passion for what they do. In my personal experience, most of them are not. They moved up the shop ladder in a corporate blue-chip automotive company with the nice Honda benefits and are where they are because of how long they stuck around probably. So be VERY cautious. For what it's worth, I will NEVER let anyone from Honda touch my S2000. There are WAY too many horror stories of complete negligence and price gouging for me. And just because they say the master mechanic will work on the car, they don't give a S***. They'll put a rookie tech on it most likely and say "go for it."
I completely agree, I would never bring my car to an actual Honda dealer as well, just for a rookie mechanic to practice on it.
Yes, I know guys...I know that the S2k outputs higher than regular/common engines, because it's a relatively high-compression motor. I actually asked the mechanics about that, "shouldn't the compression numbers be higher because of the high compression ratio?" But, they are no ordinary Honda mechanics - They actually specialize in NSX and S2000 and work on them all the time as professionals, have certificates, credentials and also are well-known in both the S2ki and NSX forums.
But, yes, I understand that consistency is more important because comp gauges vary so much from one another and may be calibrated differently to each other. Thanks for the clarification and insight everyone

Most mechanics don't do compression tests that often. So while they might work on a lot of cars, they probably don't know what their compression numbers are.
But since most cars the same range of scale usually applies, they don't need to know. 180 is awesome, 150 or lower, an aging motor that isn't going to produce as much power as it used to, but still quite usable.
So when you say your motor should be 205, that is going to sound very strange to most mechanics. To say you hope it might be more like 220-230, well yeah, that is not even going to sound possible to them. 240 is like a whole different planet.

With that said, I do it on 5 cars out of 100.
Of course 240 would be nice. The only cars I have ever seen so high were very low mile AP2s. Even they were 230 or so.
Maybe I should contact the other 95% of perfect running cars, ones that track and attend the dragon yearly, and tell them their car needs a head job.

So yeah.. "5 out of 100 cars" that request a compression check, sounds like what really happens in the real world.
thx

But really, as the guy with 4~5K track miles, 80+ rear tires roasted drifting *Orig Diff, 70K of street miles, on a used car with 4 owners. With zero mechanical issues on an original motor, with OEM retainers. At the end of the day, its not the car, its the owner. Sometimes we need to do our homework and find people QUALIFIED to work on your machine.

Master mechanics? I'm going to let Vinny tell you like it is.

But it doesn’t apply here. Why? Because I DID do a lot of research and asked around where’s the best place to go (as Vinny in the video recommends). And, several people actually suggested/recommended them in the end.
The problem and my point is, that other information (to Not got there), wasn’t easily nor readily available nor said in the public S2ki forums.
I never did “F myself” …if that was the case, the recommendations and the research I got “F’ed me”

The internet is filled with lies. Someone told me to use sandpaper to clear ice off my windshield, or that using sand in the intake can port valves, pouring denatured alcohol in the tank will boost octane, etc, etc. Point is, unless you do your homework, you taking a shot in the dark. As for how you tell, well thats tricky. Go for the one thats honest, been a staple to the community, and didn't step on everyone's toes to get there. Sure, business is business, but thievery is not cool.
Honestly I've been there, I was the first audi in the us to run corn juice, probably the world. Trusted a guy who seemed capable, motor went south 4 months later. I wouldn't trust that person to build your next motor. Idk how busy Bisimoto is but I'd go there if I lived in cali.

But you aren't actually boosting anything, your just increasing the numerical OCT rating. High OCT fuel is less volition then Low OCT and that's why its used in high boost/high compression engines because it better suppresses detonation. Alcohol is much less volatile then gasoline. Spiking your pump gas with it would technically raise the OCT in the sense that it will raise the threshold in which the fuel will combust.

Why Bisimoto? I was recommended to go there for tuning, but looking at his rates for a baseline tune being more than double the price that Church does it for and only having an hourly rate (no flat rate like Chruch) turned me away. Are they s2000 specialists like Shawn is?
