Holset Turbos, PART 3

[selmerguy]

I plan on using my current undivided mani with the stock housing on my H1C. I will fab up the vband downpipe with a new flange on the stock housing. I hope by doing this, I can just swap a t3 .70 ar housing with minimal modifications to the setup.

i have a couple questions about the turbos.... (i searched!)

i have a e316g on my car right now....i want to upgrade sometime in late summer...

but

1. my car is automatic FWD , i was told that it would have a hard time spooling it?

2. i plan on getting ecu+ in a couple weeks...it can support a max of 750cc injectors...will this be enough to support this turbo? or will i need bigger injectors?

I have an awd auto right now. When I had my evo3, it was sooooo nice. That turbo is one of the easiest turbo's to go fast on. I loved it. with my h1e, you can't spool it up without an aftermarket converter (or nitrous). I tried. The furthest i got it was 2000rpm. I put in a built auto tranny last week, and hopefully have it finished today with a 3800rpm stall converter. I'll let you know how it goes.

One advantage (and I'm sure you already know) is the extra lag from the turbo could possibly help with your launch and 60'.

I have 660cc injectors and meth injection. On 20psi I saw a whopping 58% idc. There's some first-hand experience for ya.

My h1c in a the small bep housing spools within a couple hundred rpms of my SMALL 16g with an evo3 exhaust mani, fp2x cams, stock intake manifold, ebay fmic with 2.5 inch piping, and 3 inch exhaust piping.

The small 16g is the RAVED and optimal turbo for the automatic and stock stall. So I'm not sure you'll lose any spool and launching capabilities vs. a larger evo3 16g if you go an h1c/hx35 in a small bep housing route.

420a-t has a h1e. The h1C or hx35 is as fast a spool as an automatic needs in my book. I reach full boost nearly the same as the small 16g. And the h1c/hx35 compressor flows 7-10 lbs/min more than an evo3 16g compressor. And the turbine is worlds larger than the 16g turbine.

He's likely running higher compression. Is he?

[dylan702110988]

THANK YOU!


looks like i need to find a 2g 5 speed AWD

[dsm-onster]

Well, as I stated. . . The h1c or hx35 in the bep housing with a 2g or evo3 exhaust mani and stock intake mani with big cams is still very streetable in an automatic. Considering spool speed is VERY close to a small 16g and at least as quick as an evo3 16g.

[420a-t]

8.3/1. 1g big rods/weisco pistons

At what RPM are you HX-40 guys seeing set boost? I run a HX-40 with the pro wheel and I dont see 27 PSI untill around 5500 RPM. Wheel/cartridge problem maybe?

This is with 6bolt swap, 1mm valves,272 cams, FP mani, JMF mani, 2.5-3" exhaust

First off read the thread a page or 2 back and you will see what some of us have posted for spool times.
Also there are too many variables that will affect the spool, what turbine housing are you running? what gear are you doing this in?
I make 20 psi in 4TH by 4400-4500 so im guessing 27 psi would be around high 4000's. Also i am running a t-3 .70 a/r turbine housing so it is more laggy then the bolt on.

[JWoodley]

The 6 bolt stock compression, JMF SMIM, and the 272s could account for the slower spool if you're using the BEP housing. This increase in spool time would be more with the T3 .70 housing.

[420a-t]

Well, my buddy dyno'ed his car today that I've been talking about. He got 545whp out of a bolt-on hx-35 with 272's magnus intake 3" tb, external gate, 3" exhaustout the side, air-water intercooler with ice box, (I think) 75 shot of nitrous, could have been a 50, AEM EMS, 1g big rods, weisco pistons. He was running 30psi when he did this run on a 1g fwd dsm. Rock on...

[dsm-onster]

So, what, 470-480whp without nitrous? I wish he would have done a 30psi run without nitrous.

[420a-t]

Without nitrous, he made 449whp on 23psi and 7 degrees of timing.

[dsm-onster]

Was this with the BEP housing? I didn't see you post that up. Which exhaust manifold was he using too? I'm seeing 31 lbs/min at 20psi and 5200rpms before 1g maf overrun. Versus my small 16g, I plan on seeing 40ish lbs/min with the same setup (the same VE curve) once I get her back together. But I have a stock 1g exhaust manifold and a longer exhaust pipe.

When I had the bolt-on bep housing I was seeing 22-23 psi in 3 gear at around 4450-4500rpm. In fourth probably i've seen same boost at around 4K. Check your turbo, if everything OK, may be is your exhaust/ 2.5-3"/. The discharge side of BEP bolt-on turbine housing is bigger than 2.5". Don't remember by how much, but is definitely bigger. Turbine wheel exducer is little over 2.5" too/ if I am not mistaken /.
DSM-onster knows everything about it. Ask him. You may be choking exhaust flow with 2.5" piping.

[dsm-onster]

I definately had to open up my ebay 2.5" tubular o2 housing to match my hx35/h1c BEP bolt-on housing. But, the hx35/h1c turbine wheel exducer is 2.36". The hx40/h1e turbine wheel exducer is 2.48".

[420a-t]

He has a slowboy racing cast manifold, bolt-on .55ar exhaust housing. He also has a speed density setup, no maf.

[andy4g63]

Here are a few pictures of my setup.

My mods are in my profile.

[GORBS88]

Looks awsome!! How long have you been running that setup for?
