i have a 98 gst that i am working on. the owner wants a bov but through reading through the forum i see there are different types of bovs. what is the best for this car sound and surge wise. it is completly stock except for the rims bu tthat dont make a diffence. intake and exast will follow but he want the bov first for some reason unknown to me. also is 3 inch exhaust recomended for turbod cars

 

let me reprase this a little. he wants it to sound good for a low price what is the best this i can do. does he need to get a bov or is there someway of makiing the stock one sound different.

 

Vortec Mondo. DOO EEET.

 

BOV on a dsm is a moot point since the vehicle rarely runs long enough to hear said bov.

Joking. But in all seriousness. Really.

Dsm's are mechanic's cars. If your doing the work on it, I hope your charging him...

To answer your question, the bov really doesnt make a damn bit of difference, since anything is better than the stock 2g bov. For sound, his ricer *** should look into an RFL, since thats all they are good for. For function, 1g dsm, evo MR bypass valves are an excellent choice. Venting to the atmosphere isnt a big deal on the 2g's the computer compensates for the most part, and wont stall out. It will still run rich between shifts but not nearly as bad as a 1g.

 

so i can take the tube off that runs the bov back into the intake and it will sound better is that what your tying to get at. i dont have to much experiance with modifying turbo cars just stock replacement stuff. and i plug up that tube on the intake. sounds simple enough though. but should i change it to a different bov.

 

Recirculate that bitch. Dont vent.

It's hit or miss wether or not the car will run like ---- with it venting.

The maf reads the air that passes through it at the start of the intake cycle. When it reads a different amount at the end of the intake cycle it sends that info to your pcm and your car ends up running like ***.

You need a gm maf and a gm maf translator in order to vent properly w/o running into problems.

 

It'll always be muffled when recirculated, BUT to make that MAF happy it's necessary. GST with a Greddy type s sounds pretty decent... I think the RFL is louder though (if that's all he's interested in).

 

Please spare the fellow hmt members in your area and don't run the queef sounding blow off valves that all the ricers run.

 

ricers have turbo? or are you talkin about that "turbo simulator" that they mount inside of their muffler. lol

rfl for noise! or an ebay bov sounds good too since they make a replica of almost everything.
tell your customer dude to go ton youtube.com and type in "bov" or "blow off valve". start listening to sound clips and choose whatever he likes.

 

Not the turbo simulator, but the strange queef whistle that makes the car loose any ***** it may have. Open downpipes and the like are preferred but to each his own.

Off topic but have you all heard the new detroit diesel engines with the power recovery turbine that was recently augmented? Sounds similar to a gas turbine and not a traditional diesel. I have searched youtube to no avail.
