Well just received an email that my Z is on the dyno! Can't wait for the results!

 

What dyno is it running on?

 

DynoJet

 

Latest email,

 

Good luck Robert

 

Thanks!

 

OK... Just finished talking to Bryan... Tightening the wastegates helped hold boost. Car is making 530whp @ 14psi with little timing on 93 pump. Pump tune should be finished today and around 18-19psi. Power is very smooth. Dyno graph and video coming soon once pump gas tune finished. After that... Shell URT Unleaded Race Gas tuning....

 

You should easily get to 650whp on pump gas at 18-19psi, and IMO that is more than enough fro a street car. Most guys try to keep that number around 600whp....so I wouldn't even bother with the race gas tune, unless you will drag race the car on race gas.

 

I think 650whp would be a stretch. LOL We're going to do the race gas tune for dyno numbers and to have for when I do go to the track.

 

650whp is not a stretch at all. One of my customers just made 610whp with a Boosted Perfromance Stage I single turbo kit. This was a Precision 6266 T4 .81 a/r housing turbo, with a simple short block build. No head work, stock DE cams, stock DE intake manifold:



Vince (tuner) told me that the tune (93 pump) was conservative, and that he felt like there was still 30whp left in the system with and a couple of more PSI. I think that if this customer had the .96 a/r housing 650whp would have been no problem at all.


The stage II kit comes with a larger 67mm turbo, and I am confident that 650+ whould be a reasonable estimate of max power on pump gas.

 

I guess will find out soon enough what my little Disco Potatoes will do! LOL

 

what i wouldn't give for that kind of horse, very impressive

 

Woke up to this email.

 

Car finished out at 551whp/558wtq peaking at 18psi in the midrange and dropping to 16.5-17.

 

Congrats and nice numbers.
