Holset Hx35 on GVR4

[Specter]

Any one running Holset HX35 on their gvr's? I would like to see some pictures. /ubbthreads/images/graemlins/smile.gif

Thanks!

HX 35/40 (does that count?)

 

[Specter]

Yes Sir! Even the Hy35 pics would do.

I had a straight HX35/bulleyes housing and it had good spool and power. I sold the car before I was able to dyno or track it back in 07. Not sure how reliable it was either.

 

[Specter]

At what rpms did u see boost? What boost were you running? Was the motor stock?

 

[Hksvr4]

If I can remember, full boost at 4k rpm 25psi. Ross/eagle/FP2 camps, ported head, magnus intake,

 

[Specter]

I see...in your opinion, at what rpms would one expect to see boost on a completely stock motor?

I had a HX40 on 774 and it spooled way way to slow for me. It wasn't till 4500 rpm it hit 20psi of boost in 3rd gear pulls. Maybe the hx35 is a lot better I sure hope so...

That car (which was mine) had a HX35. The HX40 was installed by the owner who sold it to you. So there you have it a hx35 comprasion to a hx40 with the same set up.

LOL cant get better then that.

Is there any room for a slim fan with an HX in the GVR-4?

There should be but the plastic might melt. I put a push type on the other side.

 

[Specter]

Thank You for the pics, so with the holset, radiator fans are a no no. Which exhaust manifold is that in the pics?

 

[Tre3zy]

i think thats a 2g or maybe an evo3 exhaust mani...

I wonder how my VGT Holset well fare....it flows between a HX35 and HX40 but spools much quicker with its vanes.....

 

[DynastyLCD]

Alan, did you find a foolproof way to control the vanes properly? very interested for results with your setup!

 

[alansupra94]

Someone was working on finding a way to control the on-board computer but many people have had great results with the regular wastegate method. I wasn't 100% sure what I would have been going with but I am thinking of implementing a way to let AEM EMS control it.

EDIT: Looks like the guy built some kind of standalone unit here:

^good read. here is another standalone some guy made on t00ners

developmental VGT Controller

This guy is a software R & D fellow so he has some resources. Check the videos. He's gotten pretty damn far, but lately there has not been much project. One day when I'm bored, and have a few more working cars I hope to tackle this similiar to the t00ners guy using a standalone controller along with some sort of tuning program (DSMlink or AEM EMS). That way you can have all the inputs you want. Sorry to side track this thread. Looking forward to seeing your progress on this alansupra, as I did a ton of initial research but never followed up on actually attempting this. There is a thread on here with a good discussion going.

Been rocking a BEP hx35 since March 05' and love it!! Prob one of the first in Chicagoland to use it.
The turbo has been reiable for me. Had it rebuilt only twice in 7 yrs, [once on GP for when my oil filter spun off during a highway race and metal ran through it.And the other time for alittle shaft 'play'/scored bearing],Both times basic rebuilt by Jeff @ TurboAuto in Nashville,TN.
Curtis ported it and welded an alum elbow on it. /ubbthreads/images/graemlins/applause.gif

Turbo hits full boost @ 4k rpm, stock bore,w/272's, JMF Race smim,63mmTB,Wiseco's/Scat Rods,stock head,etc,etc...
I'm only running 20psi[baby boost LOL] on pump gas & Im happy with the setup!
