look im not spamming my way to 15 posts i could care less about that i came for help and if you don't want to help you can go spam on another thread. Im trying to work out my budget for my turbo set up . Forums are meant for helping not flaming. Just because you know more then me doesn't give you the right to think im stupid just because i want some help. I just need some help thats all can some of you put your own setups up and maybe i can just cherry pick off of the ideas you guys put up? thanks.

1) Forums are not meant for helping. That's a by-product of their primary function
2) By definition, you knowing less makes you stupid. Furthermore, you posting the way you do, and you asking the questions you do, and making the statements that you do, confirms your utter stupidity.

Good day sir

Here. There's a sound clip somewhere in this thread.

Most of us civilized girly car owners prefer a subtle, ninja-like approach to hauling fucking ass.

A loud muffler gets old quick when you're always cruising around at 3-4k rpm.

This particular muffler is meant for a full size Chevy truck apparently.

Hey now...I like my RFL, thank you very much.



Also...Im sure I look semi-retarded right now. I could not hold back when watching the video Ben posted.

Its a shame the RFL bovs are made by an untrained monkey with autocad.

I know this thread is totally about loud stuff but i'm going to talk about my blitz since someone said bov.

I love my blitz but it doesn't work very well at low pressure :(

havy15 May 22, 2014 02:27 AM

whats a good bov for only around 6 or 7 psi since the topic of bov has arose. Also im thinking about just going striaght pipe with only a magnaflow res. any input on that?

Run without one, it's not needed except when you're trying to show off with sound instead of performance.

Now go on and tell us about how turbo is pointless unless you hear a whooosh after every shift while putting around your local hangout spot at 10 MPH trying to get people to notice you for once in your life.

triple88a May 22, 2014 11:38 PM

Fuck the turbo mang just do what these guys did.

On a side not from someone who does NOT have a turbo car (R.I.P. MSM) but has only gotten his grubby hands on every turbo book he can (with limited success) bypass is the way to go. Especially on low boost apps. Its not what people who are in it for the head turns want to hear, but itll help keep from destroying your compressor with turbo surge. Not that thats a huge deal at 7 psi.

It certainly depends on what bov you have, how it is adjusted, etc. but my experience with my Greddy type-S (not a knock-off) is that it's perfectly sensitive enough to vent air immediately on off-throttle even without buiding boost, while holding completely shut and not leaking a bit of air when it should be closed. I can stand by the motor while it's running, blip the throttle at the throttle body by hand, even just a tiny bit which builds hardly any pressure, and the moment that throttle body flips shut, the bov expells air. It doesn't make any noise when you haven't built any positive boost up, but it's operating. I've never understood why people have issues with balancing between having it sensitive enough at low psi and holding pressure at high psi..

The reason I suggested bypass over blow off is recirculation of metered air vs venting and throwing off sensory input. Is that an issue when running MAP? I need to look back into that. Assuming pressure is measured at the manifold and temp doesnt change with venting it probably doesnt matter much does it?

Using an IAT sensor with aftermarket ECU makes it a non-issue.

If you're running a factory ecu and therefore MAF, AFM, etc. then you need to recirculate it - but that's because otherwise your metered air doesn't = the amount of air in the system, it's not to help the turbo. The backpressure that is (arguably) harmful to the compressor is vented either way.
