1026rwhp. I would have laughed if anyone told me 377ci and a Ysi would do that... I hope Joe posts the dyno sheet.

22#. Centris are peaky and I wanted something with a broader yet high horsepower power band. I'm already thinking (much like chess) of two engines beyond this one. I told them I wanted a setup I won't have to buy turbos for again. There is a small chance the S261s will be traded up for something else also.

I am pretty sure I would not have sent the car for turbos if I had know it made that kind of power. Well, it is too late now!

It should be readily apparent I am compensating for something very small in my life...

Nice. I guess thats running out the YSI full steam. Turbos you'll have so much room to grow. I'm running a 1500 novi now and yeah the power is all upstairs thats why we have the juice on it to get it going. One of these days I'd like to get a ride in a twin turbo car feel the difference.

Yeah a bit too late but who cares it'll most likely come out with more power with the turbos haha. What are you running for a trans?

That Ysi doesn't have much room left in it I would surmise. You don't hear of too many cars making over 1krwhp with it but there are some. I'm still amazed by it.

Trans is a stock TR6060. It is a late 2010 build so it should have the stronger shaft in it.

Yeah that is probably about all she wrote on the YSI. Amazing numbers for sure man but the Turbos thats gonna be a whole new level I'm sure.

Nice the tremec is a stout piece I have an early 10 with the chiclets and I'm putting 900whp through it and its holding up like a champ.

Guy on CF just made 1105rwhp through a 4L80 on a Ysi. Don't under estimate them. They are great blowers. That being said, TT rules.

Blake, any idea how fast the blower is spinning? I have no idea how to calculate cog tooth count to blower speed. I'm trying to figure out how fast you are spinning it to make those numbers. I want about the same out of my car on the same dyno. Running a 8.0 crank 2.85" upper currently.

The formula I use is:
# of crank teeth/# of blower teeth X 3.45 (ysi step up ratio) X max rpm

My numbers are:
77/27x3.45x7200=70840

It also works for inches.
I *think* my crank cog is 7.8 inches in diameter, blower is 2.75.
With those numbers
7.8/2.75x3.45x7200=70455

Those figures are within 1% of each other so I would say the formulas are fairly accurate.

I realize that is above the 65k recommended by vortech but over on yellowbullet.com, there are guys spinning them to 80k, although they say not for very long. Vortech has also stated the ysi is the most forgiving blower they have.

Regardless, it is moving some air!

Good to know. I'm spinning mine to 69726 according to vortech. I hope to hit that dyno in a week or two so hopefully I can crank 1000rwhp too. Looks like I may need to swap to a 2.75 and run it at 72500 but maybe not. The one that made 1100+ through and auto was spinning it to 77k.

I did some math and using the 80T crank and 26T blower, that would spin it around 76xxx. You could always adapt a procharger pulley like I did to get bigger for the crank.

Mines in a vette, so not that easy. Already got an 8.0" crank pulley. I could drop to a 2.75" upper easy enough and put the blower in the 72k range.

Plus I have 50 cubes, and PRC 285cc LS7 heads, Ls7 intake manifold, etc that should help.

You will love the turbos. AGP is owned by two of my best friends and they make great stuff. CPR has my car right now doing my fuel system, and Joe is a good guy. He will make sure this car is good and you are happy.

You should reach the 1K mark by spinning it faster. If that still isn't enough, Steve Morris motorsports has a volute that clamps on (space permitting) where he guarantees at least a 25hp gain or he will buy it back. It isn't cheap though - $800 if I remember correctly.

I cannot express in words how much I am anticipating getting the car back with turbos.
