Holset 7m/2j dyno numbers?

[turbo87targa]

Well I'm looking around at turbo setups for my 7mgte (will someday go on an NA-t 2jz) and I've just been wanting to see the kind of power they make on the two motors. While it's on the 7m I don't plan to push it past 400 to the wheels but on the 2j setup I would like closer to 500.

Also is the hx35 capable of these power levels at lower boost? I don't think I'll be running race gas or methanol so I won't be going over 18psi.

Nobody has some dyno sheets or numbers from a hx35 (hy35, he351cw, or hx40) on a 7m or 2j?

I would also like to see some dyno graphs.

mcd? i know you have run holsets before.

I never got dyno numbers. Keep this thread going. I know there are a couple people out there that can attest to this thread. Also, Wes Beech I think has dyno numbers....

Some one just need to chime in right about now and say "look guys, for shits a giggles I put a hx35 on a 1jz, 7m and 2jz. Dyno'ed them and found these numbers with these mods"

Then we would be talkin!

The only graph I've ever seen with an hx35 was from a friend of a friends cummins. Made like 540 on 46ish psi. Can a 3.0l pull off anywhere near those numbers with less than half the boost pressure?

But, I would assume this dyno graph read over 1000 ftlb of torque. You can not compare a diesel engine with a gasoline engine, other then they burn a fuel and produce exhaust and a power output.

976tq I believe lol. Yea I know they can't be compared like that, I just wondered if it takes a 5.9l inline6 till 46psi to make that power with that turbo, how half the boost could put our motors anywhere close to the same. But I think I get it.

What I really wonder now is if these turbos run 30+psi stock wouldn't it be detrimental to the turbos health to run it at half that? I thought it was bad to run a turbo below it's efficiency range...

Bump
No one would like to share their holset power experience?

Wes Beech has a Holset housing but I believe it's got Garret guts. I did quite a bit of hunting for info on these turbos a few years back to no avail. Quite a few people have run them but no one seems to dyno them.

Not a dyno, but an example of what a massive Hx55 does on a 7m....

I've got a graph from last July at 700ft elevation. It was with the pre-1998.5 8-blade version of the HX-35. Wasn't that great of a dyno day. My PCV system was toast and oil was pissing out my rear main seal. Was about 105*F as well and my Synapse Synchronic wastegate was a PIA/lazy to hold boost. (I will never purchase this wastegate ever again) It was done on a Dyno Dynamics thus add 18% to compare to a Mustang Dyno. Approximately 403rwhp on a Mustang Dyno. Once I had more time to play around with the wastegate's preload spring, full boost came on earlier. Also added exhaust wrap which seemed to help a 100 or so rpm.

Mods (back then):
Maft-Pro in speed density
550's
2.5" piping
28x11x3" (core) intercooler
Walbro w/ 12v mod
Weiscos
ARP rod bolts and head studs
Cometic 2mm
CM stage 2 clutch

Will you be at the Toyota meet on the 27th? I'd like to checkout this setup

I doubt it. I don't have my engine back yet from a beefier rebuild.

I will have a holset hy35 dyno in the late spring early summer for everyone!! I plan to test the limits of the lil hy35 probably around 25-26 psi so it still is efficient I'm hoping for high 400s to the wheels. Does anybody have any hy35 dyno's on here? post em up guys!

 

[turbo87targa]

I've been waiting myself. Now I'm aiming at a mp t61 tho since I havnt been able to find any examples of how the hx35/40 react on our motors.

I'm lookin for pretty good response for a street car and I fear lag with a diesel turbo....

 

[88mk3supra]

a hy35w or he351cw will spool almost instantly and will make 450hp easy, great street turbos and hit very hard as well

It's a turbo. As long as the size of it is matched with your engine and hp it will "react" just fine.
