Holset Turbos, PART 8

[joyfil2001]

Hey the more that chime in the merrier. I just need a hand getting a decent base tune on my car and i'll be tweaking it from there. what injector dead time are you using? I've seen numbers from 330 to 400 on delphi 850's. I cant really find a good source that would give me a definate answer.

Did you check the wiki on ecmlink?

ECMLink says 420 deadtime for your injectors.

Well i havent heard back from gpopshop or bullseye yet about the peice that fell off my turbo, so in the meantime i just threw some washers on and tightened that bi*** down good, you could tell it was leaking exhaust from that area there was black soot all over . In the meantime i broke a turbo to manifold bolt off in my bep housing and stripped out another hole so its gonna be a while until i see what this turbo has to offer, what do you guys think would be better, to have a machine shop drill out and retap the holes? or to have a welder put studs in them?

Yes I did read the wiki and ecmlink stated on the injector deadtime list that even the numbers they post are not quite accurate.

Helicoils are designed for temperature and abuse so drilling and retapping would be ok however studs would eliminate the issues of dealing with ruining a housing.

I did do research, actually for quite sometime before I bought my Holset. I just haven't read of anyone putting down ~500 on an 8blade hx35 in a bolt-on housing.

Ah, I see. Yeah most of the 500+ HX35 results i've seen were 7blade with a T3 housing if i recall. My bad.

There is absolutely NO need to build a motor to run over 26psi on a HX35.

There is for me since i would like to make decent power and i don't think i'll be able to do that with out rebuilding my block as most of my boost is blowing past my trashed rings.

You made that manifold didn't you.
Looks great.
Wish I had a welder.
Have all of the necessary design skill and fab skills, but no access to a welder.

I'll be running a 12cm^2 external wastegate housing.
Very compact v-band outlet.
I can't tell from your pics, but is that a 7-blade HX35?
Also, when do you plan to be up and running?
Sure am interested in seeing what the 12cm^2 twin scroll housing will do with a divided manifold.

Sure did. On a dinky mig, but a welder none the less.

7 blade. Hoping to have it going soon, don't know how soon though. Maybe another week or so and I'll be driving it around.

Honestly didn't think the manifold would take this long to make, lots of test fitting, tacking, cutting the tack, grinding, tweaking. The runners move around A LOT when you weld them.

I would love to see the finished manifold, twin scroll?

Right on, good job.
Did you put the inlet flange lower than most tubular manifolds.
The ones I've seen can lay the inlet flange flat on a table top and the head flange will lay on the bottom surface flat on the table top as well.

What's your plan for a DP?

7 blade HX35 made 508 hp/455 tq at 30 psi to all four wheels yesterday. I'll post up a new thread with logs and vids when I get to my computer later.

bolt on .55a/r housing or T3?

 

[GORBS88]

So what are you saying? That the stock motor will hold up fine to the abuse? Or that he should just step up to a HX-40?

I'm just stating that the motor WILL hold up to the abuse IF properly tuned. There is ALOT of potential from the HX-35 so no need to upgrade. I Just wouldn't be building a motor to run it.

Ok. That's what I thought you were saying. The IF properly tuned is the big thing. Then again, poor tuning will blow the motor with a T-25.

Twin scroll, of course Couldn't see spending the time to make a manifold without it being twin scroll. Can't wait to see it's street manners.

Its a little deceiving, it's not all that much lower than the bottom of the head flange. I wanted to tuck it under the water pipe as much as I could without denting it. Also to leave enough real estate to mount the wastegate runners off the front of the manifold(then will 90 towards the drivers side to mount the wastegate).

The downpipe will be 2.5"(basically the size of the turbine outlet) for the first 90* or so then expand to 3". Want to keep a nice gradual bend while still being able to get the oil filter off without much trouble. Haven't mocked it up yet but hoping since I moved the turbo as far to the passenger's side as I felt comfortable it will give me some room to keep the bends smooth.

What kind of maf are you running out of curiosity? I guess my 850's will be enough afterall to push the 8 blade 35 to 25psi. And once the meth is on i'll be able to go farther. I just feel its not enough fuel. I guess i'll find out. I know cherry hill isn't a walk around the block but I would definately like some insight from you. Your set up is very close to mine. How far are you from e-town? when they have the subie vs mitsu day later on this year I plan on being there so maybe we could meet up.

As a matter of fact there seems to be alot of us in the general tri state area so just how many of us plan on making it to e-town? I dont know if ohio is in the cards for me this year. The deadline to get the car painted and tuned is coming way to quick.

I am using a 2G maf, which is completely hacked (no honey combs at all) Reason for that is I had methanol backfire one morning and it blew my one maf honey combs completely out, not knowing this I tried to drive it and my 16G ended up having a bent fin because of that hense why I upgraded to the holset and installed another 2G maf and took out all the honey combs to prevent that from happening in the future.

Btw when is the subaru vs mitsu in Etown? I have missed it for 3 years now and I really want to go! I will definitely go and we should meet up!

Also what are you using to tune with? If you have DSMlink V2 or V2.5 I can just send you all my settings, in a file and you can tweak it. But it's really simple man, just start with low boost watch the AFRs and knock and adjust from there.

7 blade HX35 made 508 hp/455 tq at 30 psi to all four wheels yesterday. I'll post up a new thread with logs and vids when I get to my computer later.

Nice numbers man! how much timing are you running?

Still have to make wastegate provisions, but.....

Been a week so far of working on it before or after work. Hardest part is done, still a long way to go though.

Twin scroll, stock 12cm^2 housing. Wastegate will be divided to the valve.

What size and schedule pipe did you use 1.25" or 1.50"?

Nice numbers man.
Where are the logs?
I'd like to see what's going on there.

doesitonall4rs-
I have v3 lite. I know that the program is quite simple. Just having a starting point takes out some of the guess work and makes it a bit easier. I have started messing with it and im getting the hang of it however Im having this weird idle surge once it enters closed loop and then stays at 1800. I command it to open loop and it only goes to 1500. Even with the tps properly adjusted and idle switch played with and biss screw turned all the way in. havent found an intake leak yet but I'm going to keep searching. The mitsu vs subie day at etown is october 23rd from 10am to 7pm

 

[bwhite]

Yea I would love to see this on the dyno. Ive been running my 7-blade hx-35 on pump around 35psi in the stock 12cm housing.

I plan on going again this year. Last year i drove my truck. Not sure what i'll bring this time since its about 2hrs & 20 min from me and I don't plan to race as of now. But this could change.

What manifold are you running and when do you see 35psi?
You say pump, but octane are you running?
Any link logs?

These numbers are very possible with a FP manifold with the .55 A/R BEP housing. I did 457 WHP with a boost leak and very bad heat soak. The wastegate dump tube was hitting the intake pipe of the intercooler. IAT shot up 70* by the end of the dyno run. I did this on an 7 blade hx-35 as well. 30 psi

93 pump sunoco. I put logs in the link forums. Look for 7-blade hx-35 over there you should find it. Oh and I see 35 by about 5.5k rpms on a cheap ebay manifold.

 

[TSIMonsteR]

I've never heard anyone say that their turbo spools too fast, . Those are awesome results roostinds.

yeah i was there checking out the log on the dynapak with Sam from RRE after and it showed 27psi @ 2800rpm

Cool, I'll check out the logs this evening.
ECMLink doesn't run on my 64bit PC at work.

 

[roostinds]

yea DSMlink shows that I hit 30 lbs. of boost by 3000 RPMs. Thats fast!!
