Holsets, who's running them and at what boost?

[Darkapollo]

Ive got a holset H1E (early HX40) that I am putting on my shadow. I was wondering who else has one, what boost they are running it at, and what RPM it spools. I have a sg5 cal for my shadow and I was looking for 20-25psi out of it.

[Turbodave]

I haven't ever messed with the Holsets, but they do sound wicked. Wallace White had one on his Spirit R/T at SDAC this year and it sounded like a big rig whenever he passed me.

If you look at the ported stock inlet of a Holset and compare it to
the same turbo from another truck you notice the inlet on the Dodge
Holset doesnt look ported. Dodge engineers actualy requested the
blockoff ring in the inlet so the turbo didnt whistle so much!

There's your usless trivia for the day

Not sure what that has to do with silencing??????

That porting moves the surge line to the left and makes the compressor slightly less efficient. Wasnt aware is created noise....?

[Russ Jerome]

The whistle was just a biproduct of the ported inlet, yes it's there
to lower surge limit by design.

[Ondonti]

i didnt know that one of the side effects was the whistle.

Anyways,
Does anyone know if there are other maps for the hx40? I was looking at the maps Frank has and the HX35 looks vastly superior to the hx40. That doesnt seem right to me as I thought the hx40 was a big compressor and just had a very restrictive turbine housing (limiting power) but instead it seems to be a 45lb/min turbo which is smaller then a 50 trim plus the hx35 will push more air and has a better efficiency island. Therefore why would you get an hx40?

[highpsi4]

The HX-40 is a larger turbo. I have not looked at any maps for it but it will be very laggy and move the power band up greatly. I put a HX-35 on my 1991.5 Dodge CTD and does well for a 5.9l. The HX-40 would really stuff it.

From the Talon world (2.0l to 2.3l) a lot of people are have great results on the HX-35. very streetable and easy to tune. Some run a HX-40 and have good usable power from about 5500 rpm to 9500 rpm.

[Rampage16V]

I've read that the HX35 is good for 550 hp and the HX40 500 -650 Here is a site for Bullseye. There might be some maps there

[Ondonti]

I dont believe any of that HP information. Its definitly crank hp numbers and they are probably overstated.

Hx40 is a 45lb/min turbo according to the compressor map.

So if there is a better hx40 then you people better make sure you are getting the right one.

[t3rse]

i'll repeat this like i always do...there are turbo lima folk (8v) making 550+ with HY35s running high boost...

Do you have a link to the MAPS you are referring to?

Also read some ppl using holset 40's are swaping in a 35HX turbine because its less restrictive

I cant find the map on that link. Just an info page
.53 kg/s is 70lb/min.

Im just saying that there is obviously a different hx40 out there. The turbo calculator makes it a bit confusing.

Another thing calling into question this information are the compressor specs you posted.

This info doesnt Jive

hx40 on that map is 45 kg/s . That info is off of another site. I just copy and pasted it . I can not verify any of it.
I'm going to put this HX35 I have here on my Rampage and I'll let you know how it works. I will be able to tell you how it compares to a T3/T4OE (A/R70) 57 trim .63A/R stage 3 Garret turbo. Under higher boost (30 or so)

Hi Dean,
How did you like the Holset?

bernie

[Rampage16V]

It rocks!!! I was running 32 psi last time out. But for a turbo I bought used off the internet for 200$ how could I go wrong~!
Spools good and pulls very hard. I know its capable of more boost then that. I am running a deltagate. It wporks good. I have a friend using one with the stock wastegate setup and he can't boost over 25 psi.

[Rod Enis]

Can any of these turbos be used on a stock 88 or 89 TII?

Any modifications needed?

thanks,
Rod
