sorry to take this out of topic, but my friend used to have a type-R that he turbocharged with a drag gen 3 turbo kit and i could barely hear his blow off...
i believe he was running around 7-8 psi...

how much boost does your car have to be making in order to get a good strong blow off? and also to get the rally style ssq sound from a ssq bov?

 

Josh, saying a d16 can't spool a t3? tisk tisk. I'm proof that it can! I'll be hitting the dyno within a few weeks, so I'll have to lay the smack down then!

 

it all depends on the blow off valve...
if you get the turbo xs RFL you can hear it from any psi :rofl:
www.blowoffvalves.com for sound clips....

 

Yea I was scratching my head when he said that cause I saw a lot of setups on d16's with t3/t4. I was like :thinking: but then was just like :dunno: Josh knows his stuff.

Let us know about those dynos asap!

 

I didn't say it couldn't, I said it wouldn't spool it well. I have personally seen a local guy with a stock D16Y8 with a DRAG kit (T3/T4) lose to SleeperCivicEX (stock D16Y8 w/ Greddy 15G kit) at the same boost level. It wasn't a one-time thing either, it happened EVERY time. The D16Y8 just doesn't push enough out to spool such a large turbo efficiently without doing some internal work. You might be able to get more out of that setup with good tuning by bringing the fuel down, but you're really wasting that turbo on that engine.

My Garrett T3/T04E's efficiency range is somewhere in the vicinity of 16psi - 22psi and I haven't even touched that yet. A smaller turbo would be much more easily spooled and the efficiency range would be down in a pressure more frequently used by a stock D16Y8 engine.

I am in no way saying that you 'can't' use a T3/T4 turbo on a Y8, just that for a stock application, there are better choices out there.

 

cool cool, you're definitely right. In stock form, it will never do it efficiently. :deek:

 

:booty:

Girl, you know it's true. :chuckles:
