I wish I could have fun with it, but it's not my car. My car doesn't have the intercooler sprayer.

 

very nice, LouZer! My apologies for doubting your power!

I'd see if they can tune out that little dip you have in your power curve around 4500rpm.

Now... must.. visit.. Z1... about Vortech... upgrades!

 

Awe Duck, you can visit for anytime for any reason ;-)

 

Yeah, I didn't like seeing that dip either. Hopefully it goes away with tuning!

 

i got the same dip, mine got better with timing changes

 

Working on that dip now. Just got to find the right solution...hmm...

 

How many psi is the charger pushing, and are they any pullies that you can swap for even more psi...i know im crazy

 

I am getting 10.5psi now. I got around 7psi with the stock 3.33 pulley and in the future I am going to go crazy and install the 2.62 pulley.... But not until my engine is built.

 

how small a pulley can you get before overspinning the impellar?

 

Not sure, but the limit is 50,000rpms (on the SC, not the car, just to clarify). At least that is what I recal hearing.

 

I believe with 2.87 pulley we are spinning the blower at 54,000rpm or better

how big is the crank pulley?

 

I know I had it writen down some where..I'll have to look for it

 

???

 

Here is a link to the NX kit being used by the 500HP G35.

here are the numbers

sc cog is 28 tooth
serp is 3.12
other cog is 34 tooth
5.73 diameter crank pulley

put those into the equation above

 

I plugged the numbers into Vortech's calculator and got these results

3.12 pully, 6600rpm rev limiter: 43,636.15

3.12 pully, 7200rpm rev limiter: 47,603.08

2.87 pully, 6600rpm rev limiter: 47,437.21

2.87 pully, 7200rpm rev limiter: 51,749.69

Based on these calculations you'd have to be running the 2.87 pully to 7200rpms to slightly overspin the impeller.

 

Those numbers are WRONG..............
You did not calculate for the JACK Shaft Ratio.
Try Agin..........

But the V2 can handle 65000 RPM

Hey....don't shoot the messanger...I just plugged the numbers into the calculator that it asked for. It didn't say anything about "jack shaft ratio".

 

the blower speed.....3.12 pulley = 54,744rpm ....... 2.87 pulley = 59,512rpm.....2.62 pulley =64,943rpm
