If you look at the exducer, the tip is flared out and curved. That's the extended tip.

Awesome, thanks for the clarification!

Diagnosis is in. Spun the number 3 rod bearing. As of right now can't see why it spun. Nothing indicates other than it was just its time. Josh did say just after he installed the turbo that the oil return line kinked itself. SO that is the only possibility right now.

It damaged the crank beyond repair. Tempered the rod beyond repair. And also damaged the crank saddle. Should have the new engine at the machine shop on monday next week after I get back from bonneville.

Picked this up today for $200 used. S362 with divided T4 housing. I'll be purchasing a BE T3 housing for it.

Your turbo has the et wheel its easy to spot. When you look straight at the compressor you can't see the second set of blades were on a normal wheel you can.

et wheel

non et wheel

ahhh that makes it so much clearer!

Thanks for the comparison!

What kind of turbo is on the bottom pic? Garrett?

Looks like it's for a WRX, not sure if it's an IHI, MHI, or something else offhand though.

Some new pics of my S258 setup, I finally got the wideband and everything in and did a couple 22psi pulls last night, definitely pulls strong!

The verdict is in. I forgot to post last week before I left to go racing at the salt flats.

Awder did indeed spin the number 3 rod bearing. Tore the crank up really good and ruined the rod as well. The bearing hadn't spun to the point where it stuck to anything, just started to wear thin and scratch things up real bad. His new engine will be at the machine shop on monday.

Looks like he is going with a 1G rod and an aftermarket piston. Wish us luck and hopefully by october he can at least have it on the dyno.

Thank you for the clarrification on that!

If you look this way at some Holsets you can't see the second set either. You gotta take the cover off to tell for sure. I 've checked the pics that me612 posted on the previous page again and now I 'm not sure. Some of them look like it is and some like it isn't.

On the other hand a buddy of mine has a Holset and its wheel does look like it is an extended tip with the cover off. May be Holset utilized that idea and never made a big deal out of it, I dunno.

Holset uses what they call Extended Back. That is were the back plate sticks out farther then the blade tips to. Where the BW units the tip extend beyond the back plate.

That is a little confusing to me. . .

Do you mean the tips of the blades in the compressor or the tips of the blades at the inducer?

This confuses my sluggish brain even more. ALL blade tips at the 'BW extended tip area' extend beyond a backplate. Extended tip or not (garrett, MHI, T-netics, BW, Holset, IHI). . .

Do Holsets run extended tip tech or not? Sorry, it seams my brain cells are donating on a voluntary basis at this moment and I'm fresh out of volunteers .

The tips of the exducer on the compressor wheel. When you look at the compressor wheel from the side. You can see the tips of the compressor wheel. On the BW units they stick out farther then the backplate of the compressor wheel (when you have the compressor wheel out of the turbo, look at the back of the wheel that is the backplate.)

NO they call it an Extended Back Wheel.

Figured this would help with your brain cell problem
Took a quick picture of my damaged 8 blade HX40 compressor. The back is ground off a bit from the excessive shaftplay, so it would stick out even more than in the photo, not sure how much more.

Link since its bigger than size allowed.

That is what I am trying to talk about. Thanks for the picture.

Wow oh wow....... so, we just took out the EVO with the 256 and hit it at 28psi with Meth and

I cannot wait until we can get this thing on the Dyno. It is going to make some SERIOUS power.

I am just wondering if anyone here would know if i can get a bolt on housing for this borg warner turbo I have. It was purchased with a huge t4 flange on it for real cheap. I want to just get a bullseye housing for it and use it that way. The compressor measures at 2.8 on the large side and 1.9 on the smaller part. The turbine is 2.75 and 2.45. When it was purchased the guy was calling it a s200. Any help would be appreciated.

I guess I have the 61.5 69.5 turbine wheel and its not available with a bolt on. That sucks!

Any update on this turbo and the power it's making? I am trying to plot out my winter plans and the S258 looks like a great choice, except no one has posted solid information on pump. Has anyone logged a run on 25+psi on the 56 or 58- bolt on housing? How much air are these turbo's moving at that rate? Any dyno or ET's yet?

Sorry for being prudent, but I'd love to take this turbo into consideration.

I will have a S256 in my car probably 2 weeks from now. Unfortunately, there was a shipping mistake, or I could've gotten you numbers by this weekend!

The only difference between the S256 and the 8 seems to be the extra 2mm of inducer on the S258, so the flow numbers should be very comparable.

Here's a link to a few of my logs on pump, I ran 11.9 @ 119 on the S256 bolt-on:

I'm running the S258 in the .70 T3 housing now, it's definitely quicker at the same boost than the 256 bolt-on, hopefully I'll hit the track next week.

Tom, new engine went in today. Just have to put the tranny in and measure for a new coupler. Going from a 2G throttle body to a 1G non-turbo throttle body. Then towards the end of next week get the GM 3.3bar map sensor installed. We can tune without it, but we might be trying some tricky new stuff. This car also has a JMF intake manifold now. Give us 2-3 weeks to have everything together and ready. I don't imagine we will see the track as there is a race on the 28th and the last one of the year on the 4th. That track is about 2-2.5 hours away though. The car will haev to be trailered. Our local track closed last week.

We will have dyno numbers before thanksgiving however. I will make sure of it. I hope you see this Josh. I am going to push you unwillingly if I have to.

Steven

, yes Steven it will make it to the dyno.

The tranny is actually on the car. I just need to plug in the wiring harness, get the coupler for the throttle body, put the transfer case back on, and a couple other little things. I'm almost there.

At 5800ft, 28-30 PSI, stock 2g MAS, BC 280 Cams, 90+ degree weather, and stock head and intake manifold, I was seeing between 45 and 47lbs/min. Keep in mind that almost every DSM I have seen go to sea level from here, including mine once, gained 3-5 lbs/min and some have seen even more. So, "theoretically" that means I could have been seeing 50+lbs/min, in the conditions stated, at sea level.

With the new setup, we will see. I would like to see 50+lbs/min at my altitude ultimately. If my tuning is on, I should produce some decent numbers. This turbo seems to be very efficient for many different altitudes, due, I believe, to the widened compressor map.

Like Steven said, just give me a couple weeks to get things buckled down and a tune done. I have my own business that I have to keep running, so I have a slight time restriction for working on the car. As much as I hate to admit it, I have a partial life outside of DSMs.

Josh

Well,

I think tomorrow will be the day it fires up, if I can get my coupler for the new throttle body. Everything else is installed. I just need to put the fluids in, install the coupler and "hopefully" start it. In the next couple weeks I should be able to produce at least some numbers and hopefully some peak numbers soon.

Josh

Well, did she start ?

I have got everything done. I am just waiting on the coupler still and I need to plug in the battery.

I'm probably 5 minutes away from startup once I get the coupler.
