Dynoed 6/29/05 Vortech untuned SC results.
Well I went down to Scott Performance today to get a baseline dyno of the Vortech I have in, I asked him not to tune the car as I am still in the process of buying parts but just needed to see what I was at.
Just like to point out that this is BHP power so you may have to deduct for powertrain loss which I have no idea how to figure out.
You will also notice that at 5500 which was a 4th gear pull, it goes totally rich and dropped right off his AF meter(actually went to zero) the stock program just dumps fuel at 5500+ rpm and just kills the power as you will see in the second attachment. This proves that the stock program is really rich plus so is idle, other than that he said it would just need tweaking here and there.
We also noticed that the kit was only boosting 7 psi and that this was not reached until 6000rpm which only leaves 500 to enjoy it, we called Vortech on this and they said they new this and that the best way to get around this was to upgrade the pulley.
This dyno was with the SC, Crawford cats, Fuji Y pipe and exhaust and a stock 3.33 pulley.
I have decided to tune this car with the unichip as the R4 program is not the greatest to achieve the best tune, this was also mentioned to Vortech and they are looking into providing the unichip in the sale of future Vortechs.


The car made 378.6(BHP) on the first run and then 372.1 (BHP)on the second. Temp was over 94 degrees today. I am going back next week to have JWT cams and springs, Techno L flash, VB upgrade and 3.12 pulley installed and maybe a new aqua mist system they just received.
Ted was an absoloute wealth of knowledge and showed me a Ferrari they were working on and I even met Greg the owner and his Porsche GT2.
