Stingy Dyno?
 

Looking for some input on two dyno experiences, on two different dyno's. After I had the base Vortech kit installed on my car I had it dyno on I believe was a DynoJet and I had it at the track. Car dyno'd at 313 rwhp and the car ran a 105 mph quarter mile at about 13.5 (street tires and very bad 60' time). This hp # matched practically spot on with the Analyzer. Since then I have done upgrades which have led to better track #'s. The odd thing is my most recent upgrade was a Dyno Tune, 90 mm MAS and 42 pound injectors. This was done on a Mustang Dyno and the numbers were dramatically lower than I expected. Car dyno'ed at 323 wrhp, 327 rwtrq. Just a tiny bit over the stock Vortech install (and much lower torque #). However I took the car to the track and it ran about what I expected with the upgrades, 12.7@110 mph. I was told that the Mustang Dyno typically generates more conservative #'s. When I plug my #'s into the analyzer I come up with 400 hp (car has a track weight of 3825 with my big behind in it). Has anyone experienced something like this before or any comments on a Mustang Dyno?

1. "Stock" Vortech: 105 mph@13.5, DynoJet at 313 rwhp, 369 rwtrq.

2. Diablo Custom Chip & PowerPipe: 108 mph@13.0, no dyno #'s.

3. Dyno tune, 90 mm MAS & 42 pound injectors: 110 mph@12.7, Mustang Dyno 323 rwhp, 327 rwtrq

mustang dynos are better for tuning and they give more of a real world ##S and dynojets give a higher number but all in all you r is making the same power on the dyno..

I would not worry about how much your car makes on the dyno but more what it runs at the track and just us the dyno for tuning

dyno #S are not important unless your racing the dyno or just need something to brag about

Thanks explicitone. You validated what I was told at the shop. But I do have to confess I would have liked the little sheet of paper with the pretty chart on it to have had larger numbers to brag about :D .

I dont blame you I think we all would :D

but look at it this way if your in to drag racing can get those little slips to brag about and that to me makes all the differance

The tracks the only thing that ever tells the truth, the dyno is always full of ****.
