If I have to work very hard against almost anything that's stock I'll be disappointed. JDM wrote my tune and figures this to be 525-550 RWHP. If I make it to the Saleen Nationals in August I will be stopping by JDM to put it on their dyno.

Why waste the time to build a motor for sub 18 lbs? You're spending all that money to only gain ~100-150rwhp? No thanks.

shifty, plenty of people build motors that never see 18+ lbs of boost. Especially on pump gas in California where i live where 91 octane is the best we got. Personally my motor will be at or above that mark but thats mine. Most people on these boards are gonna be at around 450-500 whp with boost because they are street cars and not hittin the track hard. A 18lb boost car is NOT a car most people want to drive as an everyday driver,especially in the economy we have now.If you are fortunate enough to have another grocery getter than that is a different story. But 150+ hp gain is a big gain man.and for most people all they will ever need or want.

By the way Shifty what is yur car and what are u running?

California is the perfect example of why you need to be running a low compression motor. Yeah people do all kinds of crazy stuff but that doesn't make it right or even sane. You're free to do whatever you want with your cars but high compression + boost + pump gas = not getting the most bang for your buck. Why have 500rwhp when you could spend the exact same amount of money and get 650-700rwhp? Maybe more? 500rwhp street cars are a dime a dozen. Hell, in Houston you aren't even fast enough to film a race with 500hp. You can run all the boost in the world and it won't matter for an everyday driver, you never see the boost unless you put your foot down. It's the other stuff that gets in the way of daily driver status.

In short, my car is an 05 GT, 5.0 3V stroker + 4R70W + Bullseye S480R @ ~30psi. Street car.

Make it sane? My car at 9.5 to 1 compression with boost from a centrifical blower will do fine on pump gas.and will no doubt see 600+hp from my little 2v. and a mustang seeing 30 psi is not a practical daily driver whatsoever man.500hp cars are a dime a dozen because they are harder to maintain and dont last as long.Everything at those power levels starts to go bad sooner and that is why most people settle for a 500hp car.That is the whole reason i have 2 cars.BUT most people dont. they cant afford to have a 700hp car and the maintenance and responsibility that comes with having a car like that. You argue its pointless? I say its practical and thats why people build cars like that. AND if u listened to my post above i said that the higher compression would be fine for a Street driven Centri blower car. That was the only situation i was talking about. Not a 30psi race car bro. Just because its on the street doesnt make it a STREET car u know? its pushing the limits. i also said if u were pushing more u would need the lower compression. agreeing with u. And yur car sounds like a monster bro. Any pix? u should post em up. Id like to see this thing. What type of FI are you using and who built your motor?

Having spent time in Houston (I refuse to called it living) Shifty is on the money about the insane machines rolling around town. I would be stupid to challange a mini van down there because you never know who's got what tucked under the hood. That being said, as an engineer, I've done a whole lot of things that go against the 'back for the buck' frame of thought. I could have accomplished my power levels with nothing more than a pulley change instead of the stuff I have in my motor, but that's not the way I play. I work on the efficiency principle. This video is pretty good evidence of the insanity used to descibe 'street' cars in Houston.


The other thing to keep in mind is putting that power to the ground. Even at my previous power levels (~475) that becomes a difficult proposition without DR's. I prefer to go around corners, so I run a tire that will work in that arena, which means I need to be very careful using the skinny pedal. you guys can argue this subject until you both die at age 110, and it still wouldn't be resolved. Everybody has their own agenda and ideas, and my standard comment still applies - you make your choices, spend your money and then live with it.

But yah, lets see some photos. I'm still on HoustonPerformanceDriving down there, too.

high HP numbers are just part of it. i know when i was a kid you never raced the guy with the primered piece of shit. one fender that didnt match, hood moded with a hole in it air cleaner sticking out, or fiber glass scoop pop ribbited on it. the rims on the back never matched the front.
what im saying is underneath that kid had sunk every dime he had spilled his own sweat and blood into that car, ignored the looks in favor of horse power and weight reduction, and gear ratio.
