As another data point, a friend recently got the last Pro40 that Bullseye had left, threw it on with HKS 272s and a Tial 38mm on the o2 housing, bone stock 6 bolt, full weight, and ran 11.7 @ 123 on pump/meth at 28psi spinning halfway down the track. He's experiencing similar spool to what we saw on Carl's setup, full boost around 4k.

I kinda figured that his trap speed would have been higher as well. What were his mods?

Seems like your car with the S256 does better.

As I said, he was spinning through 1st-3rd, which will greatly affect ET and MPH. He has 950s, 255, FPR, DSMlink, 2G MAF, 2900, 3", 272s, and the HX40/38mm/2G mani. He's also on 17s. With 123mph, the car easily has low 11s in it as it sits with a cleaner pass. My S256 ran a best of 11.9 @ 119 with nearly identical supporting mods. If you're talking about my current S258, that's a T3 hotside. He's just as fast (both of us in less than ideal conditions) and he's spooling much faster with the bolt-on housing, which makes for a much more fun feel on the street.

If I cannot get the Holset HX40 pro form Bullseye anymore,would the FP3052 or FP3065 be a viable option? Or are the Borg Warner options better?
Don't really wanna go BB but I see good #'s with these turbo's flow wise and track wise. In the 50 to 60lb per sq in neighborhood.

I was really counting on getting an HX40pro but this clown from Ebay lied to me and sold me a dud. I'm going back to buying new.

Borg Warner has the S360 and 362 non-extended tip turbos available, great bang for the buck. The 360 is sized pretty close to the HX40pro. PM me if you want me to get you a price on it.

NET S362 vs FP3065 vs HX40pro how would you rate them Steve? I'll also pm you 4 sure!

Bearing in mind that all 3 will be choked by using the bolt-on housing, I'd say the compressor flow would be 362>35r>HX40. The 3065 uses a 30r hotside to help it spool faster, which is significantly smaller than the others. The closer comparison would be the FP3565, which is a true 35r in the FP bolt-on housing.

My personal opinion with the FP bolt-ons is that they defeat the whole point of a bolt-on, which is to save money. A 3065 setup with v-band gate, their custom o2 housing, oil filter, lines, and everything is well over $2k. For that money you could do a T3 setup and make more power.

Yes I felt that this setup (FP3065,52)was quite expensive and worked. I saw quite a few 11 and 10 sec times using these turbs with great mph in the 1/4mile.
However ,the economics won't make sense if the same hp can be made in a less complicated way with the three turbos mentioned,namingly the S362. Just as long as you don't feel I have to chg my int mani for now I'd highly consider that turbo perhaps over the HX40xpro.

I just wish I had someone to take this New never used HX40/35 hybrid I bought from GREperformance.

I'll assume you're talking about the BEH?If it were on all three?

No, i'm talking about ANY bolt-on housing. FP will openly tell you that you're leaving alot of power on the table with even their bolt-on housing. The BEP housing is really no more of a restriction to power than an FP or other bolt-on housing. If you want the most power for your money, go T3 and be done with it. After owning the S256 bolt-on and the S258 T3, there is no comparison. I wish I'd done it a long time ago.

You mean go T3 divided A/R 70 I take it? If so I'm willing to give it a try as per PM

Not exactly. I'm talking about an OEM Holset divided T3 housing. The BEP .70 is an open housing, remember?

[ceedawg]

In what order of flow and efficiency do we rate these turbos with the BEPhsing,would this be it?:


HX40 > HX40/35 > HX35

This I believe was my understanding when I made this purchase of my hybrid.

Just curious!

[Blitz_86]

i was curious where do you get the exhaust housings like the bep and others for the holset turbos

[joeracer321]

From me

[kraka]

CeeDawg, explain the characteristics and specs of the HX40/35 you have and how much that setup runs?

I have not put it on the car as yet so I'm not familiar with it's characteristics. Ask Joeracer123 as he's more familiar with all the things you want to know about it.

[joeracer321]

The hybrid HX-35/40 was built for those who were looking for better spool up with more potential than the standard HX-35. But the HX-40 works so well that I am not sure if the few hundred RPM spool loss of the HX-40 wheel is worth the trade off of the spool. The larger HX-40 turbine has greater flow potential so I would rather lose some RPM in spool to make more top end. But don't get me wrong, if you have a hybrid, I am sure you would enjoy it as the thing is going to spool lightening fast, and have great compressor flow potential. But if I were making the decision now, and spool was not my #1 concern, I would go with the Pro-40. But I feel that these turbos are not really the way to go now. Bullseye has pretty much phased them out and unless a huge demand pops up, I don't think any more bolt on housings will be poured. The Borg Warner S series are what everyone who thinks outside the box are heading to. They spool great and make good numbers, but they are not as cheap as the Holset turbos. The S-series does offer more options and combos than the Holset's do, so you can match the turbo to the combination that you are running for better results.

Well you did tell me this at the time of purchase I have to admit.

I should have listened to you because I fully agree. However if I have to try the hybrid I certainly will,just gonna chg the turbine hsing to a T3 .70A/R divided and see what happens.
I have a feeling that this hybrid has some potential and should be better than the 60trim T3/T4 I have on the car right now.

So I can get a pretty sweet deal on a hx-35 with a mitsu-style housing on it already. Would this get me in the low 11's easily with supporting mods? How does it compare to a 50-trim or a 60-1?

Also, would 272 or 280 cams be best for this turbo? thanks

[dsm-onster]

The hx35 is comparable to a 50-trim. It seams to flow around 50 lbs/min and actually spools a little quicker.

50-trims are low 11 second capable.
