I learned from my past experience with the motor blowing on my s2000 is to only take my car to someone who specializes in that car, and to make sure they look over everything before tuning.

There's a lot of people out their that claim to be tuners that have no idea what they are doing. There's a lot of things that can go wrong and if they don't specialize in that car they might not catch it.

As I said, there are much more consistent, better/safer delivery systems/configs to use for power support application.

It all depends on your definition of "reliably." If there's anything I've learned over the years it's that hitting numbers on a dyno for the sake of hitting numbers is just dumb. There are plenty of dyno queens out there though.. Some tuners will brag that they've hit X number on pump gas, etc. etc. Of course you may hear months later about that customer needing a new motor (most likely you won't though). Also, there are way too many variables at play. Are you trying to hit 500whp on a t66 or t25? One flows a whole lot better than the other.

Ultimately, imo, if you want 500whp+ to run around on, you'd be dumb to just use pump gas. Get something with more cylinders to handle the load, and you can make 600whp on pump all day. Is race gas cheap? Of course not, but neither is a new motor. As others said, the more you push the limit, the smaller that safety window becomes. My opinion is better to play on the safe side, should you get some bad gas or something acts up, you won't be needing a new block.

No sir, that's not my definition of reliably. What I am referring to is making decent power that the car can handle without overdoing it for the given setup. Like my soon to be installed setup. KW kit with 91 blower and 85mm pulley. I chose the larger blower and smaller pulley in hopes to run a little more boost and have a little more power than guys running the bare bones kit. However, I want to do that safely so the car can still be reliable when boosting around every so often. I'm not trying to max the kit out or overdo it just to have some massive HP number, but with that said, I still think the car should be able to handle what I'm expecting it put down (450 or less) and not blow apart just because I use 93oct. E85 is not available to me and I'm not trying to push the car or the SC kit to its limit to where I need a water/meth injection to support 93oct fuel. I don't live in VTEC and I don't track the car, but when I want to have a little fun and romp on the gas I want to know it's not going to take a dump.

I'm looking for around 450 reliable horses too next week using the Vortech v2 and the 3.8" pulley, plus the rest in my sig.

Going to who I hope to be an expert, Granite State Dyno in NH.

I hear it's all about that bass (no, I mean tune and fuel delivery).

Supercharged and turbocharged are 2 totally different things. A 450whp Supercharger will always be "safer" on pump gas than a 450whp turbo charge car. The reason behind that is that the supercharge car doesn't make full boost until redline while a turbo car makes full boost around 4500-6000rpm depending on the setup.

that's just my personal opinion though.

either way, just put some E85 in there and make 500whp on a stock motor no problem. !!!

I love the aem meth kit. Works great, faisafe setup works perfect as well. If any error, ecu dumps fuel and pulls tons of timing instantly. Great kit!

While I agree that over 500 is a stretch for pump, I don't agree that over 400 is. There have been countless cars on this forum alone that were tuned over 400 on pump 91-93 and are still running strong.

Like stated, there isn't enough information to 100% point fingers here but, you have 3 competent tuners who aren't happy with the fuel map posted. That says something.

Everything comes down to the experience and confidence of your tuner. They will let you know what they believe is the limit that is within their "safe zone" based on your entire setup. The better the tuner, the more aware of this limit. Even a poor tuner can make a great deal of power for a short period of time.
