Holset Turbos, PART 5

[JusMX141]

If anyone's looking for a HX55, this is a STEAL:

eBay Motors: NEW HOLSET TURBO HX55 - CAT,CUMMINS,MACK,VOLVO (item 160299426869 end time Nov-24-08 19:43:14 PST)

It even comes with a spare billet compressor wheel. Act fast, it ends soon!

I don't know how you can say a hx52 won't be streetable when no one has come on with spool characteristics other than the hx52 dyno thread. Which actually doesn't look much different from a gt35r powered car which is a streetable turbo.

Also, that was with a non-divided manifold i believe.

 

[chrisb33]

Guys,

what size of intercooler pipings (cold and hot side) do you suggest to use for the hx35 with stock intake manifold? 2.5" or 3"?

what if i use a SMIM? 2.5" or 3"?

thanks.

2.5... 3 is a little overkill.

 

[northendtrooper]

SMIM is only good for 16gs. Anything bigger than that you'll heak soak it. I suggest an ETS FMIC.

northerndtrooper,

i already have a big FMIC FYI. SMIM = Sheet Metal Intake Manifold

See I was kind of wanting to wait to how it spooled with the twin scroll manifolds you and the other guy are running (forgot his name ). I know bigladies friend was running a non-divided manifold so there for it was seeing the full size of the exhaust housing. I mentioned the thought to my friend about running the 52 and he said it was just to big for the street but I mean 6k isnt bad especially if your willing to rev your engine some, and he also had cams which will slow spool. Anyway I can't wait to see the results.

 

[airmail96]

Also I don't think he is exactly saying it won't be streetable I think hes saying that the car with a t3 .70a/r housing will still be very streetable, but I'm not sure .

Yeah that's a smim not a smic

Did you look at the splines on the new shaft? If they were pointed or worn you might want to start looking for one in better shape. This is a common problem. If the splines are worn you will probably have the same problem again.

They seem OK. It is not brand new, but is in a god shape.

 

[northendtrooper]

Yeah I was a little tired and I go dyslexic when I'm tired. Go 2.5"

It would be nice to see the .70 a/r bep housing cut for an hx5* turbine wheel!!!! The Borg-Warner s370 is very similar in flow and wheel sizes to the hx52. BEP sells this turbo with the .70 a/r turbine housing correct? The .70 a/r housing has a smaller area than the combined area of the TS hx52 turbine housing. Spool should be faster, but still good enough flow to keep up with the hx52 turbine wheel. If it spools before 5K that would be as 'streetable' as a little fpred with the 8cm^2 turbine housing

I agree with IPT, the hx40 is good for over 600whp and has impressive spool speed. Any one who wants any more power for a 3100lb car with great traction may have inferiority issues J/K.

Lol I almost resent that j/k. I'm cool though because my hp goals are greater than 600whp and my car will be lighter than 3100 so I don't fit in that category Not to mention that I will not be running a 2.0 motor and plan on spooling to full boost before 5k

All of the hx5X that ive seen all have v-band attachment to the chra like the hy. I dont think we will be able to get any BEP housings because of this.

It would be really helpful to know what size housing was used in the hx52 dyno thread. I have one that has a T4 16cm^2 housing. I took some pictures of it next to the T3 16cm^2 hx40 housing that i wish i could use and they look very similar. I think this would probably spool fairly well with a divided manifold.

T4 hx52 on left, T3 hx40 on right, both 16cm^2

The inlets are obviously different, but the volute looks the same size.

Slippi84, what size is your hx52 housing?

 

[airmail96]

Weren't we suppose to get some dyno results today

To be honest with you I don't even know from looking at all the hx52's they all looked pretty much the same. Yours actually looks a little small I have some size pictures maybe you can tell from the pics how yours measures up to it but I simply looked at it as a t4 divided holset housing that is about 1.04-1.14ar.

It looks like it might be the same as the one i have. Its kinda hard to tell by the picture though.

The housing size should be cast into the inside of the inlet like this

If not you should be able to go by these casting

Yeah they're the same mine says 16 too.

Dyno booked for Monday the 24th 9 A.M. 600 or BUST!!!!

Almost 500whp at only 26psi of boost is absolutely awesome considering the compressor was being pushed to it's absolute limit with a big enough boost leak to keepo a 40+ psi turbo from going much past 25psi with a 2.3L and a SMIM. You have only a 2.0 with a stock intake manifold. 33 psi will net you well over and a more efficient spot on the compressor map.

I'm confused, you have an AWD in your profile, you state you can to 100mph FWD burnouts, but you have a 1.7ish 60ft. If you have an awd with close to full weight then you already have proven to have a 600+ whp setup. Most guys prefer trapspeed with a known weight over an dyno anyway. MPH doesn't lie and is more consistant across the board than a dynomometer.

It sounds like he installed a VCE to dyno in FWD or has a switchable tranny for the dyno.

 

[airmail96]

Wow gorbs those numbers give me a lot of hope for when Iget my car rebuilt next year. Seems like I'll need to make sure to get some meth

hehe i have installed a VCE for the dyno time so my times were on a AWD chassis which isnt full weight but is still a tank. The 133MPH traps say more then the 485whp for sure. Not sure how much the MUSTANG dyno affects it?

 

[dsm-onster]

Do you know your race weight?

Did you go a pump gas with meth?

 

[northendtrooper]

GORBs. I read your results on the turbo and since its on a Mustang Dyno you're well over 500whp on a Dyno Jet. Can you post up a Dyno sheet? So if you were boosting under 30psi and putting down those #'s on a Mustang Jet is pretty damn impressive man. Bravo!
