I see they now make a GTX3582R. No 37 series yet.

Shows more hp potential than the 3788?

Now's your chance!

I know its been a while but I started a new job last fall and didn't really have time to go dyno but we had a dyno day a couple weeks ago and he finally emailed me the graphs for comparison. So here are the results.

Nothing too huge as far as numbers but it spools up a bit sooner and gained power. I am not really sure his dyno is loading it enough but this is a good comparison. With the s300 it was at 48 psi and with the Garrett it was at 43 psi, but I have seen 45 (wastegate setting) with the Garrett on the street before. I am really impressed with how this injection pump has good top end power. My stock pump would taper off pretty quick. The Giles pump does much better and now with the Garrett it stays higher even longer. On the street I feel like there is more difference in spool than the graph shows. I think my next upgrade will be intercooler and 3 inch tubes. I also have a snow stage 3 sitting here waiting for install.

That profile is fantastically flat over 2500 rpm. As you say, on paper nothing huge gain-wise but still SMOOTH power. It's almost a mirror image of the S300, just upped a touch numbers-wise. Can't wait to see the numbers after the IC/water-meth install.

What were the specs on the old S300?

I bet that was in this thread somewhere and I was too lazy to go back and find it.
