winding up the boost is too damned addictive i have two turbocharged cars one is running silly boost of approx 28psi, i did run 30psi but it started to det so i quickly turned it down, the car has a Garrett T25 hybrid unit (stock is a lowly IHI VL7..approx T2 in size) comp ratio is 7.8:1
the other (200sx) is running pretty much std boost of about 7psi
the other (200sx) is running pretty much std boost of about 7psi

BMW's turbo F1 engines, back in the day, ran over 4 bar of boost. It's not known whether that's absolute (including ambient air pressure) or gauge (just the extra boost). Either way, it's a minimum of 43.3 psi. 😱

Well, I disagree with you there.. Euro sports cars go slower for less mileage than their GM counterparts... and the GM cars usually cost way less. I am very happy with the build quality of my GTO compared to the 97 Z28 and 99 Trans Am I had before it.
I did think about a Solstice but I hate soft tops. I like hard rigid bodies in a car, as it improves handling. The turbocharged 260hp version coming out next year would be cool if I could get it with a solid roof. So, I went with the GTO and the turbo.

Hey I'm in the Bay Area and may be heading down south sometime. You should PM me your SN or something and maybe we can hook up when I'm down there. I want to hear the 18 psi out the BOV. 🙂

What are you running 28 psi of boost on? I'm jealous. 🙂 I will someday lower the compression ratio of my LS2... 10.9:1 is too high for a lot of boost. I'm sticking with 5 psi! I can go to 7, but I don't want to push it.
Then again, 10.9:1 basically gives me 55 psi extra inside the motor for 5 psi of boost from the turbo. Does it really matter if the compression is in the motor or in the turbo?

Hmmm...I might have to disagree with you on this one. A standard, plain jane, 6 cylinder Mustang is a decent car. But, when you consider the performance packages of the Cobra, Boss, Bullit, and to a lesser extent, the GT, you now have a relatively inexpensive Sports car. Inaddition, Rousch and Saleen take the factory mustang, add re-engineered suspension and engine modifications to create rally-handling, performance cars with gut wrenching speed. Certainly not cars to be driven year-round in the harsher climates. And these cars are available at select Ford dealers throughout the country.

I'm not sure what the exact figures are, but I suspect you're right. Ford is probably looking to the supercharged Cobras and second party tuners such as Rousch to add significant horsepower to compete with the Camaro and Firebird. It will be interesting to see what will happen with the new Camaro and if it will be produced-and how much!

The Mustang GT has 300 HP with the 4.6 V8. The 4th gen Camaro SS and Firebird Trans am has a 320 HP "detuned" LS1, but stats say that is underrated as Dyno's put it at the same HP as the LS1 that was in the C5 Corvette which was 350 HP. It is sadder that Ford has to supercharge an engine to get the power any where close or passed a N/A( No turbo's or superchargers) LS engine. It took a supercharger for Ford to produce 460 HP for the Cobra Mustang to outpower the LS2. I have a solution for Ford. Bring back the V8 Pushrod in Fords lineup. I mean if GM can get 505 HP out of the LS7 pushrod V8( plus 16/26 fuel economy) Ford can as well. Hell, even the 4.6 DOHC Northstar V8 outpowers the Mustang GT with 320 HP. Don't get me wrong. I want the Big 2( Chrysler doesn't count in my eyes since being German now) to return to profitability.

Perhaps lack of competition has something to do with it. Until this year, there really hasn't been any competition in the ponycar bracket. Now with the Camaro coming again, the Chargers and Challengers, and even the Magnum, it's a good time to be looking at the musclecar market.
interesting
Sup I was wondering why you were going with the turbo charger instead of the supercharger that seams to be all the rage. I like the turbos better myself but getting the views from the owner them selves is just better. My dad had a 80's model Mustang that he had put twin turbos in. He use to street race. Now I'm noticing that the superchargers have become more for the street scene and the turbos norm on the strip. do you do any racing in your car..... and what does the thing at the end of your page mean?
