There is a 500 HP club using AI
https://www.rx7club.com/auxiliary-injection-173/500-pump-ai-club-628209/
That seems like an honorable goal. Doing all my research, i found that people were unlikely to run higher than 15 psi boost pressure until they used water injection on pump gas. Now the bar has been raised. 500HP requires ~20-25PSI depending on tune, port, etc.
I dont think 600 is as common. It seems like an exponential goal. it takes 5X the effort to go from 400 to 500. It seems the same if not more for 500-600hp.

I can not imagine any 600rwhp 2 rotor running pump fuel. The money you spend on race gas will be penny's compared to the build and supporting mods. If you cant afford the c16-q16 for when you want to crank the boost up I would shoot for lower numbers. Not like anyone drives around running 30psi on the streets daily!

There will be several cars here running 94 octane and Full methanol injection in the very near future including mine. The meth kit will be a full custom setup. The goal is the mid 600whp range for the street so stay tuned for some numbers!!

Sorry, I am not sure if he was including E85 in that group of "pump" fuel. If so, then yes I do agree and take my above post back but I am thinking he is refering to regular old 91-93 octane stuff. In that case I just dont see the reason for taking the chance with it. Can it be done? I bet it already has but how safe for the average Joe that is not tuning his own car and relying on another tunner? How long is that motor going to last? I like the idea of my gas coming in a sealed container so I know 100% what I get. To each is own........
On the E85 thing, I thought long and hard about doing it and maybe still will, but there is only 1 pump in about 1-1.5 hours drive from me. I am sure that falls true for many others as well.

I honestly dont see a problem making 600whp on pump and water. If I had a bigger turbo, I wouldnt think twice about it.
Im currently making right around 500whp on my GT35/74 at 22psi. I could run a GT42 or a S372 in the mid 20's and it would make 600whp with the same amount of stress my motor is going through right now.
Not a big deal on pump and enough water (600cc+).

how long has you runing the number on the pump. my last stock engine blow up on me at 400-450 on pump for good 2 years.

600 rwhp on pump isn't a problem but you'll have to get a big turbo which will be laggy and lots of supporting mods. For similar amounts of money, you could do a 20b if thats your power goal. Or if you have deeper pockets 26b, 800 rwhp all day easy.

If you start thinking about how much money you have to spend on a 600 rwhp 13b, you realize its not much more comparatively to go 20b. It is not double the cost, you need more then a turbo to make 600 rwhp on a 13b. Also, you can sell all your 13b parts when you go 20b.

I have to agree wight the above posters, 600whp 13b is still going to be cheaper then a 20b turbo. If I switched out my 850/1680 to 1000/2200 injectors and my GT35 to an S372 and ran the same amount of boost, then retuned, I would easily have 600whp. I also dont care about lag.

About 5k on the motor so far. It's a weekend/drag car so it doesn't get driven a lot, but when it does, it gets driven hard.

No one ever said it was cheaper. Think about how much you spent on your car to get to that level. I'm talking about from start to finish including everything like labour.
If you already have your setups, yes it would cost significantly more, but if you start near stock, the amount of money you spend is a lot closer then you think. If I could go back and start over when I bought my car and have everything I know now, I could build a 26b turbo with a Motec ECU and everything else for less money.

Even with that taken into consideration I still agree with them, I also build my own motors and do my own tuning so that helps a lot with costs. I spent around 5k to get my motor into its current state, I think a stock 20B alone costs around that much? Also, like dregg stated, why do that when you can make 600whp on a 13B? If I were going 20B (which I would never) Id be shooting for 800whp+.
