You will need a mechanic/tuner who has a clue and whatever parts he determines in order to run on pump gas, and your engine will be safe with as many pounds of boost that is determined by a professional who is tuning your engine. If you expect to read a generic number off the internet and apply it to your own ghetto setup with your own ignorant tuning, then you may as well just save yourself a lot of time and money and drive your car off a cliff right now and be done with it.

this is just a question for those who have a similar setup. stock engine,btw no ghetto setup,mechanic tuner good enough to run mid 7s in the 1/4. if you don't have any input why end your response on a negative note ?

It's the truth. Sorry if you don't like it, but that's the way it is.

Not sure what 76/96 ar means...... 76mm compressor inducer and 0.96 hot side A/R?

Evil Aviator blasted you because you're asking a college-level question and providing grade school information.

Figure around 400 rwhp at 15 psi, and if it is that big of a turbo it's too large/laggy for pump gas boost levels.

your right about the turbo. i ask questions to learn a little about them.this is not my first rotary but it is my first turbo. bashing won't go well with me. i only take that face to face. . i'm not a punk and can defend myself. thanks for the info. and thanks in advance to anyone that can share some info and experience with what i'm asking.

A lot also depends on your engine builder, fuel system, and tuner. there is a pretty wide tolerance from low to high, both with boost levels and power levels.

If your turbo has a 76mm compressor and the engine is built and ported correctly, you can make close 480rwhp on pump gas.

Maybe even 500rwhp if your dyno is on the juice.

Your 93 octane is equivalent to our 98 octane and i have tuned a fair few cars to 17-18psi with no problems.

I have pushed some cars to 22-23psi with no ai but you need to run very rich and need strong ignition for that otherwise youll make less power.

You should definitely consider some AI to keep your engine in check at those levels. You can probably do it without, but it's that much more of a safety margin. If you're going to be dragging, you'll have to go with pretty much straight water, Reg's don't allow for methanol to be injected.

Looks to be a pretty bad *** car you've got. But, with that big of a turbo, you'd be better off on race gas and turning up the boost, or going with a bit smaller of a turbo. You could probably do the same with a 62-67mm turbo

Who's the mechanic/tuner? mid 7's is this with a rotary?

Also why pump gas? Is it mainly a street car?
I would probably run a low boost setting on pump and a race setting with good fuel.

I personally think 400~450 is a good number for pump gas.
Anything over I would suggest some sort of AI.

JUAN LOPEZ GREEN 3RD JEN----- FREDDY & RICO FROM SAM RICO RACING-- RED 2ND GEN, FREDDY OWNS A 3RD GEN THAT IS ONE BAD CAR ONCE IT GETS DIALED IN. SHOULD BE OUT 2010 RACE SEASON. ALL FULL CHASSIS RACE CARS. RICO JUST RAN A 7.63 @181 IN FL,THIS CAR IS GETTING FASTER AND FASTER. SHOULD RUN 7.40S. AFTER THIS UPCOMING SEASON I'LL DECIDE IF I WANT TO GO 8s. AND YES IT'S GOING TO BE MAINLY A STREET CAR, I WOULD LIKE IT TO STAY THAT WAY FOR A WHILE.

I know freddy and rico from the fountain ave days. I mainly raced bikes but i also had a 82 toyota starlet ladder bar car with a bridge ported 12a. I never went to the track back then but the car was quick. I'm lucky to have friends that have proven fast cars that can help me out.but i also have to ask others for there opinion while i'm learning. I thank everyone on this site for positive input.

dont forget your personal car thats at like 30+psi with 700+rwhp!!

obviously you must have meant without aux injection.

but to the OP, you can get a lot more power with water injection, especially if it is a properly dialed in setup.
