Congrats! You'll love all the whistling and pssssh sounds...as well as the added power!

I bought mine used so I wouldn't know, but isn't there a break-in period?

sounds great! so you are pretty comfortable in running mid 13 times? do you think you can bring those times to low 13's with practice?

I just needed couple more runs on friday. Next friday I should go to low 13s. By the way this is my second time at the drag strip, first time I ran stock with an Aem intake and did a 14.3@94mph best. This was my second time. I'm a fast learner. Couple times I fouled with a 0.48 sec reaction time. All the others were 0.5x launces. That's considered as perfect launch. Let's see how I'll do next week. For more go to street encounters about major ass kicking last night.

Can anyone explain the way the bypass and blow off are triggered? I assume it's when the throttle is closed the vacuum in the intake is used to actuate a release valve. I can hear it hissing when I'm not on throttle.
Both work on the same principle. Both measure the pressure in the intake pipe and the manifold. If the pressure in the intake pipe is greater than the manifold to a certain level then the BO valve opens. This is to prevent the pressurised air from bending the throttle valve. This is very important in supercharged car as there is no other way of releasing this pressurised air other than slowing down the car....which is a lot slower than slowing down a exhaust gas driven turbo.

There are only a couple of differences between the 2
1. Vortech vent to air and comptech is plumb back. Therefore Vortech's BOV is louder. The attachment is the same as turbo charged car and you can replace it aftermarket/louder BOV.
2. The vortech one has an adjustable peak pressure release. Similar to a pressure cooker. I wonder if anyone has play with this and try to get more boost? May be Jason, jenner or merlin777 can comment about this becasue they have used smaller pulley. Did you guys have to play with the peak pressure knob?

My car normally psssshhh at rapid close throttle at high rpm. It also hisss at constant partial throttle at high rpm. I wonder if I can raise the peak pressure by playing with the peak pressure knob. Has anyone done it before?

I guess it depends how far you drive your car. If you only drive the 1/4 mile then an SC may not be the best value for money. Of course if your races, like mine, last a little longer than 13 seconds then you will appreciate the SC.

I've always wondered what the appeal of the drag race is? Is it racing for ADD sufferers.

well stock s2ks can run high 13's but at optimal conditions and driver skill. not to put down any of the drivers wh own a sc, but a high 13's on a sc could result to numerous reasons. 1) driver probably is not pushing the car as hard as he/she would stock because he/she does not want to fix the rear diff too soon or 2) they are still learning to launch with the sc since the high 13's on stock are not very normal, people usually run about low 14's to mid's for the average driver.

also traction is an issue and if you read in his original post.. it says he is quite a bit above sea level which would result in a half second difference as if he were at sea level + it was his 2nd time at the track. with all those set aside, if ur just crunching numbers.. hypothetically a high 13's driver on a stock s2k at optimal conditions would and most likely be able to run low 13's or even 12's considering traction all day on a sc s2k. hope that makes sense!
