Stage 1

[DC2]

[?]Got my stage 1 today from the local dealer. Took 45 min.to instal and 1/2 hour to do the trans quick learn procedure. Anyone who is on the fence on getting the stage 1 this was the best money I have spent. The car runs so much smother and performance is what it should have been all along. When you charge $28,000 you should get more than a siruss radio. This turned a great car into an outstanding car. I don't run my car that hard (baby it) but I do want the performance if needed and the stage 1 gives you that. 16 psi boost and holds steady tell you let off the gas. step on the gas from a roll and the tires lite up. my bov is still on backorder. does it make any improvement in performance or just sound good?

THE stock bov is a recirculating one and sends back pressure towards the turbo which slows it down causing turbo lag and eventually will mess it up. The mopar bov and other aftermarket bovs vent into the atmosphere, you won't have turbo lag and your turbo will last longer. Without turbo lag you will get better response which is an improvement in performance and the sound is really cool. You'll love it!

Also, the factory BOV recirculates thru a 3/8" hose that is over a foot long with a U-turn, making a bottleneck, That is the main reason you hear "flapping" noises at the turbo intake when you remove the air silencers.

With the MOPAR BOV you have four 1/4" holes venting to the atmosphere for total of a 1" exhaust, there are no lines to create a bottleneck so the turbo won't loose it's inertia and recover real fast. Since I installed it, the "flapping" noises are gone.

This is what happens when you increase boost and don't have a good BOV:

If you increase boost and don't have a good BOV, when you let go the Accelerator, the excess boost will create a return wave stalling the turbo impeller or even reversing it for an instant. This creates incredible stress on the fins and in many cases, the impeller explodes and throws shapnel to the engine.

I learned this the hard way with a GN...

Well, I'm no rocket scientist, but I DO know that four 1/4" holes do NOT equal a 1" hole. Nevertheless, the venting IS far superior than the stock setup.

Just trying to keep you honest, Ian.

To be exact:
(4)1/4" dia holes = .19 sq. in.
(1) 1" dia. hole = .7854 sq. in.

Ups....

Sory about that. I was thinking linear, not squared.

Thanks for the help. but still, it is better than one 3/8" hole. Right?

woohooo!
Ordered my stage 1 today....
heh, almost got pulled over today too...was passing aggressively. cop followed me for 4 miles before turning away..scared the crap outta me...and no S1 yet.

You are correct sir, a 3/8" hole has .11 sq.in. as opposed to the .19 sq.in. w/ sum total of the (4)1/4" holes you previously mentioned.

I used to ask if one would rather have (2)8" pizzas or (1)12", most would pick the (2) 8".

12"=113 sq.in vs. (2)8's=100.5 sq.in.

Oh well, I'll be glad when my BOV arrives and is installed.

I would prefer the (2) 8" pizza...because I really like the crust
