ya the 3" vband has def been one of the best things i love about this snail...makes it so easy to bolt up even w/ 1 person....

Bubba tuned. He's a really cool cat.
Ignition pickup was missing on the dyno, so no torque curve.
This was on 91 pump @11psi. I wanted to go to ~15psi, but Bubba said that the ecu/solenoid were actin' funny. Overboosted a couple of times, once to 28psi and another to 30psi. I don't really know much about that particular part of the AEM software and Bubba's the man so.........mbc here I come. So, I'll try that next and see how it does.

 

looks pretty good...that 9cm is def helpin out the spool along w/ the cams...def some rome for more for a nice build

yeah i like the vband end of it. I really dont like the BEP housing because of the dsm exhaust flange on it. But this is interesting.

He doesn't get boost in first gear, but in second and on it spools at about 4k and makes 15 psi by 4500-5000 rpm and that's just on a 1.6 SOHC with a log manifold. I'm sure if he ran a divided collector manifold we'd get spool a little earlier. I'm very curious to see what happens when we block off one side of the turbine. </TD></TR></TABLE>

if he can spool it with a 1.6. Shouldnt i be able to spool it quicker with my 1.8L? Maybe i should just try it first and decide what i want to do. I dont mind working on my car . Well atleast crome has the new antilag script. I'm sure i could use that to spool that sucker up for 1st gear at the track

 

well even w/ just crome's 2 step i build about 4-5psi at 4000rpm open dp....next year im gonna get antilag going...just so i can make some noise even when i puttin thru the stock exh to scare all those ricers.....hell everyone tells me to rev it up to hear it...and get pissed when i hit 4k...theyre like whats wrong? im like nothing...its how i set it up so i can launch....everyone is clueless heh...

yeah i didnt like the mitsu housing either ont he turbine...but if it was my choice id just order a 12cm non-wastgetaed housing w/ the 3" vband....its on a link to a site on here...or even paul prob can get it for ya...was somehting like 170ish if i rememeber correctly....

also you have to account spool time decrease on the d16 because he's using a log mani....itl help spool it up a bit faster but will lack the nice smooth flow of exh pulses higher up int he powerband....therfor makin less power....

Thanks. I really wanted to see 350whp on 91 oct. But the solenoid (new gm soleniod) / ecu (new as well) were acting up. I will get an mbc, turn up the boost ~2psi and remove the cat to see if it will get me closer to my goal. Bubba was a bit concnerned about the 350whp using pump on stock sleeves, I thought it should be doiable, but he showed some concern. He also said that they do things a bit on the conservative side there, so that explains a bit of the hesitation. I do have some new wisecos (for b-series) and scat rods (b16) just sittin in my room right now. If it blows, it blows and then I'll builid another one.

ps - anyone wanna trade some ls or gsr eagles or scats for my b16 scats??? I also have a cometic hp (for nos and turbo, stock thickness) hg for b16 and a set of king bearings for b16's that I need to get rid of. All of them brand new. Anyone interested let me know.

They are available with a T3 inlet instead of the Mitsu inlet and look they are on sale!!

 

Also the V-band adaptor is available in 2.5" or 3" (Flange only no clamp or insert) $95.

Free Shipping on purchase of V-band and housing together.

 

yeah i know there is a t3 inlet. I just dont like the dp flange portion of it. I already ordered a clamp and flange from paul. Its nice that he's local . I'm just going to look for a 12cm^2 hx35 housing. Anyone have one for sale. Cheaper preferred.

 

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by drumking15 &raquo;</TD></TR><TR><TD CLASS="quote">ok dave il try my best w/ my holset knowledge....youy could actaully measure the a/r if you wanted all youd need is a caliper and some way to measure the inside of the housing...caliper etc...here is a pic to kind of describe what im talkin about



now that you understand this i can explain a lil more in detail...

the stock 12cm housing is what we refered to as a divided housing...where you could use the exh pulses to actually help spool up the turbo faster than just the exh gas pressure...this is often refered to as a split scroll turbo...hence the split in the turbine housing...now w/ the hosuing intact the a/r is around .55 , now if you were to grind out the divider and increase the area obviously the a/r raio is goin to increase...hence why when you grind out the divider the a/r is approx .63

now w/ the bullyseye housing its a .55 housing that isnt divided....so there is no restriction of the gas pulses hittin it if you were to run a undivided manifold...and you dont have to grind out the divider and increase you a/r...also bulleyes had internal wgs that you can add on to their housings making it a good setup as a whole...i still run an external gate...but if space was a concern...the internal gate would be an option...

now remeber when you decrease a/r....spool will be lower in comparison to engine speed...as when you increase a/r...spool will be higher in engine speeds....the problem is if you go to small on a a/r it will choke down the flow of the whole system...so a balance of both worlds is what you shootin for for an street car....whereas a drag car you could neglect the spool losses for increased power potential...and just build the car for the higher powerband

well i think that should siver it mostly...if you have any more ?'s postm up </TD></TR></TABLE>

Thanks, great answer. I already knew how to measure the ar and stuff, I just thought the cm converted to ar one way or another. I am asking because I am going to buy a non wastegated 12cm housing for a hx35 I am getting, I have a brand new hx40 as well I think I will get an hx35 14 or 16cm non wastegated housing for to make a hybrid. I know about twin scroll housing's as well. I build and design manifolds, I am building one for my tdi right now, twin scroll, for this hx35 I am going to build, I am gonna use twin 38mm wastegates, one for each tang.

Once I get that set up I want to try compound turbo charging, I will keep the 12cm hx 35 I think for the small turbo (high pressure) unit, than maybe use the hybrid 14 or 16cm hx 40 as the large (low pressure) unit. And use a 44mm external gate to control the low pressure turbo. The thing is while I can fab manifolds and flow heads like no bodies bussiness I am not a turbo a wiz, and could use some help or suggestions for my compound turbo quest. I know these turbine sizes will work for my given flow, but its the compressor sides I am not so sure about.

I have built one compound turbo charged vw diesel before, but I think it could be better. I am running abour 40 psi on these motors by the way, so the holsets seem like natural candidates. Any suggestions help way appreciated, if I should make another thread I will, just thought I would post here in the holset thread because those are the turbos I want to use.

And sorry I know its not honda stuff, but you guys seem to be open to cool projects, not just elitest honda stuff, thats why I kinda hate the vw scene, its VW or nothing, regardless if its inovative or not.

 

welll ill do my best to help ya out...havent done to much research on compund charging....but i know its huge it tractor pullin world and diesels....

 

so does anyone have a spare hx35 12 or 14cm^2 housing they'd like to give up for a small amount?

 

I have an 18cm^2 housing I would sell cheap

That's what we did, just tried it. I had it sitting in my basement while I was trying to find a smaller exhaust housing, wound up buying an Hy35 instead so we just threw it on his car.

I think you could get a decent spool off of it with a B-series, but on his car while it spools decently, it really needs a blockoff plate or smaller housing, or a shot of NAWS. The car gets eaten off the line and just can't spool the thing quick enough to make it up later in the gears.

I would try it, worse case, you'll need to source a new exhaust housing.

 

Thats the plan

 

just thought i would post up my dyno sheet . finaly got to the dyno
red was the first run and blue was the last run


setup:
b18a stock bottom end, stock head
colt cams
precision 780cc injectors
custom ram horn mani
holset hy35w ~ 6.75psi
2.5" charge pipe
cca intercooler
blox IM
4"-3" DP
3" cat
RSR catback (killing my power, 60mm piping, chambered muffler)
tuned with turbo edit
i think thats about it

feel free to coment.
next year im puting in a new clutch, maybe put in an e-cutout, go to 10 psi and hope for the best.

 

i assume the power is okay for only 6lbs. Run 15 its the new 10

 

This may seem odd, but how much power would one of these holsets, say an h1x, make without a wastegate on a built ls? We have a motor we are going to try to run into the ground stock and then built.
Are these things capable of like 40psi or something absurd like that?

 

itll spool up well beyond what the motor can handle...the problem w/ holsets is thet love higher pr's....running them at low boost isnt such a smart idea...it be better gettin a smaller turbo....you wont belive the difference once you take it past 10psi w/ a good exhuast...

15psi w/ stock exh i have traction...10psi open dp i have zero traction...but transient response is absolutely crazy!

That would get extremely messy

 

bump for an excellent thread

has anyone mentioned the H1E? Is it similar to the H1C? I can't seem to find helpful info.

EDIT: H1E has the same turbine house as the HX40, thanks TTT

yeah they are high presure turbos havent seen any 4bangers run at 40psi yet but the dodge truck guys do

 

guys, i have a 81mm ge sleeved ls/vtec w/ divided topmount and a 12cm housing hx35w. im a little curious as to what this turbo will support hp wise tops, ive heard rumors of 500 or alittle more, and ive had people tell me it will only do in the 400s. i flows about 55 lb/min correct? so if you think 10lb/min is good for 100 hp, then theoretically it should flow well enough for 550whp.

i just dont want to go to evans, and have him be like yeah, you coulda made 500 plus., but your turbo is out of steam. my goal is 500-550 whp btw.,

any help is appreciated.

 

bump!
