Taking A Little Spin With 583 RWHP

Last night I spent a few hours at a local dyno shop. A friend of mine invited me to see how his car would do on the DynoJet. His car is a '94 GT sporting a Trick Flow intake, Twisted Wedge heads, and a Procharger S/C blowing 18 psi among a few other things. As it turned out, the numbers were not as good as expected. You see a few weeks ago he had his car on a Mustang Dyno and it cramked out 693 RWHP, so he was more than a little disappointed to only see 583 register on the DynoJet. Anyone have any ideas on the big disparity between the two brands of dynos? I know there's some variance, but over 100 HP difference?

Anyways, after the dyno test session he took me for a little spin. Let me see if I can describe the expirence. His car spins the speedo faster than my car can spin the tach. His car pulls harder at 130 mph than mine does in the middle of first gear. At the top of second gear, when his car is finally starting to gain some traction, and the blower is really starting to spin, you no longer feel the pressure of sitting on your ass, you only feel your spine pressed to the back of the seat. To summarize: WOW!!

I've been reading alot that there are huge differences between the two. I think they read the power differently or something but I think the biggest problem was the operator not doing something correctly. Im sure if you did some browsing on some forums you'd find lots of threads between the two.

Just curious, do you know what this 583 HP car runs in the 1/4 mile? Or zero to 60? Just curious. I have ridden very fast motorcycles, but have yet to drive a car that will run faster than about mid-13's. The bikes I have ridden would do the 1/4 in about mid 11's and a 0-60 in about 3 seconds. I've heard guys say that a car "feels" much faster than a bike when accelerating at a similar rate. I am curious as to how much faster this 583 HP car is than the bikes I have ridden, just want to get an idea of the difference in "wow" factor between bikes and cars. Sounds like the 583 HP car was REALLY fun to ride in! I once saw a show on TV.... guys were comparing a relatively new Vette to some crotch-rocket bike at the strip... the bike of course beat the Vette, but the Vette was still pretty fast.. was running somewhere in the 12's... it was one of the faster ones. Anyway, one of the test drivers (who raced both the Vette and the bike) commented that the Vette "felt" faster than the bike even though the bike was about a second faster. He felt that perhaps the sitting down position of being in a car adds something to the feeling of acceleration over the position of straddling a bike. This is interesting. I hope this is true since I am getting more and more into cars again now and getting away from bikes.... and I know I will never be able to afford a new street car that will be as fast as the bikes I have ridden. I somehow think I am still gonna miss those near 3-second 0-60 runs though... I guess you need something like a Ford GT if you want to go that fast with four wheels.

Bone stock GT (circa 87-93) will get you very high 10's or low to mid 11's with that much horsepower. How the car is setup suspension wise is what will make the difference.

I know that a stock GT went 10.97@134mph with 565 rwhp.

I think the feeling that the car is faster is because you sit lower. Just to try out a go kart and you'll know what I mean.
