I used a garrett GT3071R don't know how close it is to your turbo but there was no 67mm, haven't played with to many turbos with this program so don't know how close this is.
WOW!
I TOTALLY appreciate the effort you went to to come up with these numbers!
I understand that they are necessarily "ballpark" figures because of my incomplete turbocharger information, and other considerations, but they are probably within ten-percent of what that engine really should do.
That is all I was looking for and I REALLY appreciate it!!
I plugged those numbers into an online calculator that I use that I have found to be reasonably accurate and learned that the 10-pound boost configuration should produce real-world acceleration numbers in the high 11's at about 113 mph, while the 20-pound-boost motor might go close to 10.30 @ 129 mph! Our car weighs 2,840 with a 170-pound driver on board, and according to your figures, should go 14.4 @ 93mph with no boost all.
It "feels" about like that (with no boost, that is.)
You have given us information that gives us something to shoot for and we thoroughly appreciate it!!!
We'll be going to the strip to do some test-n-tune in a few weeks, and will update our information at that time.
In the meantime, I have one more question but I don't want you to spend a lot of time on this; it's no big deal, but if you still have all the tech data in your program relative to our motor, it may be a relatively quick and easy thing to do:
I have altered a set of rocker arms to yield a 1.6:1 ratio (rather then the nominal 1.5:1) and was curious as to whether the different valve lift afforded by these rockers would actually affect the total hp numbers, once installed. They would increase gross valve lift from .484" to .516."
No other changes.
If you don't have time to mess with this, I understand. You have done a LOT for us...
But, if it's just a matter of changing that
one parameter in your program, it might not take long to do.
Again, thanks so very much for those figures!!! You da man...:cheers:
