Where did you hear that the Greddy Type S is too leaky? Just wondering becuase i have one and i was wondering if that little ba$tard is leaking my valuable boost

 

OT: I'm glad you're back chris.

 

The Blitz SS doesn't cause compressor surge at idle. In fact, it let's out a whole lot of air at idle. It does however cause compressor surge when shifting between 2500 to 3800rpm because the spring is too stiff. Between those RPMs, the blower is pushing less than 1 to 2 psi of air, not enough to push the spring and lift up the metal plunger, so instead the air goes the only way it can go (ie. back through the blower). The Blitz comes with a spring for cars running up to 16 psi, but at lower RPMs, the SCer doesn't generate anything near that.

 

Ha, thanks steve. I kinda lost interest in the car for a while. Just got frustrated with it due to some cv joint problems, but i'm back

 

So how does the stock Bosch BOV/bypass valve perform? I'm still using that. ?

 

i don't know about that one, never had it. Anything that can hold the boost and get the air out when needed is suitable. The vortech racing bov gives me chills though. its huge.

 

So when are you going to be on display Mr. January '06 MOTM?? It's already the 24th!

 

I put the stock one back on temporarily over the holidays and it actually did its job perfectly. The Bosch unit has a weaker spring (good up to 10 psi). I had no compressor surge at all with it, it just didn't make any "pshh" noise and doesn't look very cool. Other than that it did its job well. Honestly, I would have just stayed with the Bosch if I didn't find a softer spring for the Blitz.

 

I guess it didn't happen. Its just what I was told. When are you going to post pretty pics of your setup?

 

Ha. Good q. I am torn. Do I do it now with nothing to back up the (hopefully) gains? Or do I wait until I install my two channel intake temp. so I can post the intake temp. drop across the aftercooler? And/or do I wait until I dyno to show some (hopefully) HP gains?

I guess James or I can start a new thread with all our pics.

And then measured results can follow.

I do have all the pictures just sitting in my "C:\Maxima\aftercooler" folder waiting to be placed in a new thread.

We'll try to get on that soon Steve.

Steve, Jim is stoked - we went to buy his Jackson Racing kit and we just assumed my luck of finding a used one was a one time shot but since so much time has elapsed, our contact actually got another used one in! Used = $425, new ~$900.

 

Damn, that's a good price. When are you going to dyno? You are preparing for a 2.87 pulley safely?

 

Oh and we were discussing BOVs in this thread I think:

We will need to drop pulley sizes, you're right. My 10PSI dropped to 8.5PSI after the aftercooler install. :/ I have a 3.25" pulley now. I don't know that I want (nor am I prepared for, to answer your question) a 2.87" pulley. I wish there was a 3.00". ?

 

Stephen Max had one made at asp but there is a wait for one.

Thats a deal. Does he have any more? I'm looking into trying to make more space in my engine bay.

 

Stehen Max had what made??

I think he only has one right now. But he gets them from time to time because his Miata customers trade their JR water to air systems in for his custom made air to air. I can probably negotiate a discount on a new one for you or I can tell him to contact me the next time he has a used one. But, in your case, it seems like it is a waste of money since you already have a pump and a heat exchanger. Perhaps you can buy just the aftercooler itself from Jackson Racing? Or how about one of these barrel design aftercoolers?

(although they seem a little pricey and a little large)

 

a 3.00" pulley

maybe. but i was thinking of selling my kit, although it is unique, it takes up so much room in the engine bay that if i have to work on something, i have to take EVERYTHING out. sometimes its a PITA.

 

I still think I'am going to give a shot and besides, what's really the worst compressor surge can do??? It really shouldn't hurt anything.... I'll guess we'll see.

Do anybody have this HKS SSQV??? Speak up if you do.

 

I do. But I can't report on it yet. I just installed it days ago and haven't driven the car since. I have never heard of this compressor surge stuff until now. I figured if it works well on my Supra, it would work well on the Maxima. Apparently not from what people are saying. I'll report back after I investigate.

 

Thanks Wizard, that'll be a big help since I only has 1 week left for the install. Let me know about that.....

 

It gives you this nasty "PHOOM" sound and it puts extra unncessary wear on the blower. Charged air is not supposed to go out the way it came. If compressor surge wasn't an issue, then why should we even run a BOV/bypass valve at all?? Why not just have a solid charge pipe from the blower to the TB, lol.

 

That's true but I just trying to find the real reason for giving up on $235 Bov, for alittle surge????? Well maybe I will get the Blitz, but that's down the line, my car needs to be on the road...LOL

 

Expect to pay $350 for a blower rebuild sooner I guess is a reason.

 

Well you could spend 10 dollars and go with the Bosch, lol

trust me, this is crappy news to me also man...i dont like how my blitz sounds...but i know its doing its job...
