Supercharging stock 5.0

Unit 5302,

It seems that no matter what I say, you think you know it all. A car may make 360rwhp on a dyno in perfect conditions. Once at the track, perahaps making pass after pass, he is no longer making 360rwhp, maybe less with a heat soked engine. Running 12.9@110 in a car that weighs 3500-3600lbs with driver, on street tires, is plausible with 360rwhp. There was a guy on another site posting a run of 121mph with 370rwhp. Different tracks show different results. Remember, temp, density, condition of the track, and driver all play a part in the et and mph. The only time I have run my car at the track on street tires(before pp, crank pulley--best dyno of 380rwhp/367rwtq), I started ofd running a 13.7@108 and finished with a 13.4@112 on a hot miserable day. I definitely didn't gain power that day, especially with back to back runs. I was learning how to drive my car (still have lots of learning). Could it have gone faster than 112, I think so. Good weather would have really helped. On my last pass, it was hot, my engine was hot, so was I making 380rwhp? Probably not. I know my little Powerdyne was burning to the touch so it must have been blowing nothing but hot air. Just because you plug numbers into a computer or magazine race doesn't mean you will run it. Try it sometime. Not as easy as it seems.

Sorry brother, a 6lb supercharger on a Cobra with GT-40 heads, exhaust, and maf, can and does have the ability to flow enough to make 360rwhp. Ask around. Go to dyno shops, ask them. Do real research instead of arguing on the internet. Have some facts to back up your information. Matter of fact, call Swansons or Powertrain or LaRocca's, or True Blue performance. Ask the pro's. Then again, I doubt they have your expert knowledge.

By the way, I'm just curious as to what supercharger you run? You have all this knowledge on supercharging so you must have some sort of power adder to back it up. Experience is knowledge, know what I mean.

Swanson Performance is known as one of the best not just because of the power he is able to pull from cars but how they drive after the tune. My car ran horribel before, came out running perfect and still does to this day. Ask about him on a site like the Corral. Get some real responses. It's okay if you don't take my word for it, there are others. I gaurantee Danny doesn't play games. To many tracks in So. Cal where cars can back up the dyno numbers. He races his car and other racers go to him and depend on his ability to tune their cars for max performance.

When Vortch advertises hp gains from a sc, as far as I know, they advertise what gains would be made on a stock car. A good tuner can do better than that. As the mods are added, heads, intake, cam, etc., that power will just go up.

I have read about guys with 347's making 400+rwhp. Some guys at the Corral have 306's making 340+rwhp. It's all in the combination. It's not always peak numbers that matter anyway. My friend's combo may peak at 361/362 but a guy with a good running 347 may peak less but have more power/torque under the curve and thus a faster car.

Those fans on the dyno's may make a difference with an intercooler but they don't seem to be that stong in my opinion. In tuning my combo, I have 39 dyno runs. Two different dyno's but both were a dynojet. Guess what? Both put out very similar curves and numbers. No big deviations. Dyno numbers are just numbers though. That's all I have right now. I will eventually get track numbers to back up my dyno runs. Learning to drive will definitely help me out a bit.
