What is the typical % quoted for Z drivetrain loss?

Between 16.5 and 17.5%, going by alledged bhp and dynojet measured whp with SAE corrrection (higher whp typically found with STD). Lower loss value is typically associated w 5th vs. 4th gear pull.

So... about 17% on the average.

i put down 335, where the dyno averaged for baseline 270-280

you gotta remember people only give there best runs... my drop to as low as 330-334.7 so what does that tell you?

it was at performance motorsports in long-island

love to see more NA power but i dont think there are any economical cost options

After the tune Did it feel like you really gain that much power ?

Well I know Z1 has a package that provides 340 bhp w/ their modified intake manifold, headers and test pipes. I believe this is not including intakes and cat back exhaust. And even then you could install come pulleys to give you that little extra power. Idk what it would yield but I'm sure it would be pretty good NA with a tune.

Isn't that how they ended up with the 342 number they're claiming?

"In conjunction with a Stillen Gen 3 Intake and a quality high flowing exhaust system the Z1 VQ37VHR 400HP Package can produce 340+ rear wheel horsepower on a DynoJet on 93 octane fuel when properly tuned with Uprev Engine Management. We have not included the intake, exhaust, or engine management systems in this package because many people have already purchased these items. We recommend installation and tuning through Z1 Motorsports."

that 340 number is with intakes and exhaust that just inst provided with the kit.

also i still dont believe that number to be true. that would be like my car gaining 20WHP from headers & manifold addition. with the whole rate of diminishing returns of mod HP i dont see a 20WHP jump.

This might be a some what valid question for NA cars but I don't believe the loss is consistant once you go to FI. I believe that there is a certain amount of upfront drive train you have to overcome no matter what and then some percentage additional beyond that depending on power level.

These are my numbers, just HP since I don't have the charts directly infront of me:

- Stock - 262whp (Dynojet) - 90 degrees
- Full bolt-ons (Stillen CBE, Berk HFCs and G3 Intake) - 299whp (DynoJet) - 80ish degrees
- Full bolt-ons (Stillen CBE, Berk HFCs and G3 Intake) - 299whp (Mustang) - 70ish degrees
- Full mods and tun - 314whp (Mustang) - 70ish degrees

I dyno'd 342 at Z1's dyno when I got my tune. At Znationals, it was in the 320s during the dyno competition on a hot day with heavier wheels, but still was the highest NA Z there, by a good margin that day.

I think they were using 4th gear at the dyno competition to save the dyno brake. Hence the lower numbers.
