mustang mike 302

Hey, he has M-90 .Rated at 435 hp at 6psi stock. He has the 8psi pulley ,my guess is 475ish . Thinking of taking it to performance dyno in Loudon N.H. in the spring for a tune. My car is stock Coyote 2012 for now but thinking hard on a V-3 Vortech.

cool thanks,

Have you had issues with your insurance company? A fellow worker was interested in supercharging his 6 cyl convertible but when he checked with his insurance company, they told him his insurance would be voided and he should seek another company. so far he has not been able to find an insurance company that would allow this. seems strange since they will cover a supercharged shelby. any comments or suggestions would be helpful.

No problems at all. As a matter of fact i showed my broker the car when bought it.

Shelby's are built supercharged off the assembley line, so they come that way and the insurance company has to suck it. If you supercharge a regular car, the insurance company thinks the only reason you're doing it is to race, and that means you'll wreck on the street while racing, and when the propane tanker truck you hit catches fire, it blows up and kills dozens of innocent bystanders, which they have to pay for because it was your fault. All because you wanted to supercharge your car. Easier to just say "no coverage" and keep the streets safe for our kids and keep everyones insurance premiums lower.

My first stock motor was at 110,000 438 RWhp Auto. With a whipple H.O. 10lbs of boost. Probably at least 20 Dyno runs numerous different E-mail tunes and lots of play with the throttle. I had a stroker on order so I beat this stock motor and trans was bouncing off the rev limiter one night doing donuts in the rain. Bang broke a rod in half and put pieces thru the block.This was definately the weak link in the chain. Had I not been bouncing off the limiter and fooling around this probably would not have happened. As I had just done some full pulls on the Dyno the week before. I now have a stock motor with about 150,xxx K I'm not too sure about the mileage exactly. I have a TVS2300 3.5 in pulley With auto trans. Can't seem to tune it past this limit or it starts to ping with 404 RWHP and 395 RWTQ With about 8- 10 pulls on the dyno. AFR 11:3-11:8. As I am still building the JDM short block I will be a little safer this time. I will be putting out the question about gas soon and why I cant seem to pull off better numbers. Just did a 5 hour remote tuning dyno session with two guys from a company in Indiana.Excellent tuners who have been around for a long time. Trying a lot of different stuff. Not my field so I don't know what all they did.Have made fooling around with this car a hobby but what an expensive one.If your wondering why the stroker is taking so long. That would be a private conversation.Hope this helped a little with your mileage question. I personally think fatigue would come into play around 150,000 if your up around 10 lbs. But there is so many variables around safe tunes and heat etc. It just makes for good reading i would hope.And maybe save someone some bucks along the way.

To the original poster. I am using a non forged 4V motor in my car with an eaton swap. It has the same rods as our gt. Blower is set to 9 PSI and it make 459 whp and 440 TQ. It has seen about 25 passes at the track and lots of street duty. Dead reliable thus far.
