or should I get the vr4 upgrade cuz I'm really just looking to get 8psi min and 12 max and then take it to a custom tuning shop?

so I think i want to put it on and run it for a while and see how I like it. If I like it and want to upgrade later how would I go about doing this?
I get 9 psi with my sn 2000 with the modified impeller with N2O to cool the charge.
Do a surch on upgrade to VR4, it looks like the VR4 upgrades are being sold again now.Originally Posted by shadowgames81

I searched but found nothin showin how or where to get a vr4. I gonna run the sn-2000 and a 75 shot of n2o to cool it till I can find a vr4
on cundnracing site the impeller he sells as a modified impeller is the one I have in mine and he sais it does 8-12psi does that sound right
I don't believe it gives more psi but it increases the flow a little bit.
The VR4 upgrade can be uptained at: http://www.paradisewheelsinc.com/
and : http://www.cundnracing.com/servlet/StoreFront
Give them a call and tell us the results if you please.
Thank you.

Nope, Not right No matter if he has it listed that way or not. If you would see a increase in boost it would be because you drop the pulley size way down(3.25") and the unit would be at max rpm by 4k engine rpm. The problem with all of this is they will take the PSI reading at the blower casing not at the Engine. I have been doing this a long time and never have I seen a 'SN' post those kind of number unless it is used on a 4cyl which your filling half the volumn and at 45k blower rpm. Install your blower then see what you have and go from that spot. It takes 15 minutes to remove the blower on a Mustang after it is installed so changes are fast and easy. Bench racing/guessing gets you no place because of engine condition and parts selection.
sounds good. thanx for the help. I'm gonna put it on and run it then later try the vr4 upgrade and then move on to something bigger than that after I have more knowledge on all these. Will it be ok to put the 75 shot of n20 after the charger to cool the air or will it be too much??
That's alot. I use a 25 shot. If all you're after is a cooler charge, you can't, and don't need to, fire a power-adder size shot into it. 75 you're going to have to fuel for and the point is just to cool the charge you have, not add to it and be in the same head-gasket burning place that prompted you to cool the charge in the first place.
F=MA
oh ok I thought I had to get a 75 shot kit and jet it down or somethin but 25 would be good to run to cool it though?
