do i need to have a blow off valve

[0range_Kouki24O]

i didnt put a blow off valve on my car. people has told me its fine without it but i just wanted to make sure if thats healthy for my car or not

[Murdered_T]

ummmm.... how are you holding boost? or, how are you not boost spiking?

Moving this to 240 tech.

So long as you have some sort of diverter valve on your turbo system, you'll be fine. The stock setup will have a diverter valve next to the side mount intercooler.

Sell me your car.

Or come to my friends shop to get work done.

Either way...

Holding boost and boost spikes are effects controlled by the wastegate, not the blow off valve. OP yes. You need to run a BOV. Intentionally subjecting your turbo to surge is stupid.

what about older factory turbo cars? my 300zx turbo has no blow off valve, no intercooler just straight pipe from the turbo to tine intake manifold.

[redtop91]

IIRC some CA18DET's didn't have BOV's. Like Bart said checking for the bypass valve will let you know if you need to run anything aftermarket or not. FWIW the bypass valve tends to be a little leaky in my experience.

everyone thanks for the replys. i had two friends drop by just now to talk to me about it and my best bet is to just get a blow off valve

[Dead Serious]

if u werent running any kind of bov or recirc then with one u should see less turbo lag because surge decreses the turbos rpm between shifts.

whos your friend and wheres his shop

[0range_Kouki24O]

any suggestions on a good blow off valve ? gredy type-r or blitz supersound blow off

Either go with Tial or HKS.

The main reason older cars and some new stock turbocharged cars dont have BOV's is because low boost level surge does little to nothing to a turbocharger.

you get what u pay for......a friend had an rfl that leaked and one had a forge that came with stripped out hardware and wasnt adjustable. i have a second gen hks and it works perfect even after some elemental abuse.
