Quest for 500's

dcoker7705 · Mar 7, 2017

Hello fellow dsmer's!
I want to start off by saying I'm not a complete newb, just new to this forum. I current have a 92 talon tsi producing close to 400hp on pump gas. I'm currently trying to hit 500 hp to the wheels. There are tons of extremely knowledgeable members on this site and I thought it best to seek advice before purchasing anything for the build. With that out of the way I will start off by listing what I do have already.
Evo III 16g
Fp manifold
Magnus intake mani
750 cc inj
Aem high flow fuel rail for looks LOL

Aem afpr
Aem wideband
BC 272's
BC bee hive springs/titanium retainers
Eagle rods
Weisco pistons
Walbro 255 lph
Dsmlink v3 lite
Masft/ gm maf
Ebay front mount and piping

What changes would you guys make to achieve that goal? I'm thinking of running a holset hx35 but Im worried its not gonna spool like I want. What injectors would you guys recommend? What other upgrades should I consider as well? My budget is around $5500 thanks in advance!

HX40 is laggy but all depends on how you want to drive it. I see full 36lbs at 4700 just for thought.

I've decided on a hx35 twin scroll with v band housing... I feel like that's going to produce the best results for what I'm trying to accomplish. My goal is to be hitting hitting full boost at 3800. Might not be achievable but it's ok to dream! :hellyeah:

I've already order v band flanges and pipes to build my downpipe. Shouldnt be a problem I've had to build downpipes before, this will be my first v band though.

I would recommend not getting those bosch CNG injectors. They are likely the worst possible choice for a big injector.

Have you ran them before or is that a through the grape vine kind of thing? I want to go with FID 1600s but thats gonna kill my budget. I still have to send tranny off to be built. And If I can squeeze it I'm going to replace my Megan racing coil overs with feal suspension.

Maybe I misread something, but if you have a $5,500 budget what else are you getting that you can't swing for FIC 1600s? As info, I made 502 on a modified fp green, e85, stock 6 bolt bottom end, and fic 1100's. No need to make it harder than it needs to be.

Having trans built thats over half.... need a new clutch, still have to get injectors, and new exhaust mani probably going with obx mani unless I can find a cheaper alternative that I don't have to sacrifice quality for. Plus the little thing fluids and tuning those are the little things that got me on my last build. :aha:

tylersevo · Mar 9, 2017

I'm so lost.....why would you ditch the fp mani for an ebay one? For a clutch, act 2600 will do.

Won't have the clearence to run the fp mani with the hx35. I've seen ppl on here that seem to have made it work, I personally don't want to dent my waterpipe and have it that close to my block to make it work. I'd rather have more room to play with than not enough.

1990TSIAWDTALON · Mar 9, 2017

Until I could afford a tubular manifold, I ran my FP mani with my HX40 and a BEP housing. On some you have to dent the water pipe and on some you don't. It doesn't effect anything anyway except your pride.

I tried to use a Ebay manifold and it had so many leaks at the head flange that effected tuning that I literally threw it away, so beware, you get what you pay for.

When did obx mani's become ebay

I'll keep that in mind... as soon as I find a decent turbo I'm jumping on it!! I'll check fitment and let your guys know how it goes...

1990TSIAWDTALON · Mar 9, 2017

The inducer or A inducer is laying on top of that beautiful Gold Valve cover.....its not an oil cap LOL

drcolt · Mar 9, 2017

Has there been any porting been done? Seeing as you have a $5K budget.

yeah I see it now! I wonder if he had that made or just glued one to the cap...

drcolt said:

No but I will be doing that when the head comes off... I seen a felt a difference with the magnus intake mani, I'm sure it will be much more significant when both sides are port matched. Didn't really need to be done with the 16g because as we all know they're spool happy... I know I will need the extra airflow to get that hx35 to spool quicker.

dcoker7705 · Mar 18, 2017

Scored a really nice hx35 thanks to @lasershark . I have some concerns with running my current c/r with this turbo though. Seems like 9:1 is too high to run with these especially since I plan on run 30 + pds of boost. I know the popular choice is 8:5:1 running that much boost but wouldn't a little higher c/r than that produce more power on the low end until I get into boost?

joejoe · Mar 18, 2017

Honestly You won't even notice the difference. From 8:5 to 9:1
And it's not high at all.
Will you be running e85 or meth injection?

A few People have ran higher than 11:1 on e85 with 30 plus psi.
My friend had 10:1 e85 fp3065 35psi daily. No issues.

Correction he was at 31 psi daily.

English racing was running a 11:1 setup with a pf3065 that made 619awhp. This was several years ago I'm not sure if the "turd" is still around.

dcoker7705 · Mar 19, 2017

I'll be running e85 for sure. I've been reading up on it and I do see a good number of people running 9:1 with no issues so I'll stay where I'm at for now. Only thing I'm unsure about is the turbo is a twin scroll hx35 which is great, but I was planning on running my fp t3 manifold. Will have to change the housing or will it spool and run with no issues w/o a twin scroll mani?

dcoker7705 · Mar 22, 2017

https://www.extremepsi.com/store/product.php?productid=22341&cat=0&page=1

So that's my choice of manifold I'm ordering today or tommorow. Guy I talked to at extremepsi recommended that I go with the twin 44mm v-band setup. That doesn't sound right to me because they aren't capable of going over 20 psi correct? I plan on going over that... also I was always told that the larger wastegates were for big turbos running low boost. So my question is wouldn't I be better going with the 38mm wastegates with my 30 psi goal in mind?

Oh and another thing what happend to red jack racing? I can't get ahold of anyone... jmf is the only vendor I could find that still makes a t3 divided manifold for our platforms!!! :idontknow:

Thanks In advance

Message Kyle, he might be able to do a t3 divided for you. I think Redjack stopped fab'ing stuff.

A divided t3 is going to really limit your turbo choices. The divided t4 flange has the most options.

For what your goals are you could have just bought a dsm76, had super fast spool, and met your power goal.

Already purchased a 8 blade twin scroll hx35. I'm kinda stuck with this direction now...

Man that's no good they made a beautiful manifold. I'll give them a shout before I pull the trigger on this jmf mani. I know they make great products and have good quality. But I feel like theyre price gouging a little because they know theyre the only vendor with a t3 divided right now. That's just my 2 cents though....

donniekak · Mar 22, 2017

Why not just buy a t3 non divided housing for the hx35? You'd save on the manifold and wastegate.

The problem is that the divided t3 flange isn't a popular footprint for performance turbos, and it limits flow.

I wouldn't base a $2,500-$3,000 setup around a few hundred dollar turbo with an uncommon footprint.

I will definetley keep that in mind. I just really wanted to utilize the twinscroll housing. I have been informed by several people on here and elsewhere that it is well worth the extra money. I don't see where it will make all that much difference myself. How much of a difference would running a twinscroll manifold vs a non divided t3 manifold make? My guess Is achieving full boost only a few hundred rpm's sooner, which doesn't seem that significant considering the cost. This will be my first build using a t3 turbo and running 25 + lbs of boost. That is why I'm relying on what people tell me and what I read on here.

1990TSIAWDTALON · Mar 23, 2017

With a twin scroll aren't you just getting half the exhaust hit??? That's the way I was looking at it when I made a choice plus I have alot of options with my open T3 as far as Garret, BW, Precision or the Holset that I run. Just something to think about. As for spool time, the bigger the wheel the slower it spools unless you spray it, really. That's just their nature but something I have gotten used to.

donniekak · Mar 23, 2017

That twin scroll will help it spool faster. However a single scroll .70 ar hx35 doesn't exactly spool slow. This also depends on the size of the twin scroll housing you have.

The problem with putting all of your eggs in a t3 twin scroll basket is that almost all other performance turbos are built around a t4 twin scroll footprint.

No not necessarily... in an undivided collector there is a greater amount of egt, you loose a good amount of energy that could be transferred to the turnine wheel. In a divided setup it lessens that turbulence which allows more energy to be transferred to the turbine. There are other benefits as well lower exhaust Temps, better boost response, more power throughout the power band etc...
If you have any extra time this is a good read! http://dsportmag.com/the-tech/twin-scroll-vs-single-scroll-turbo-test-the-great-divide/ good toilet read for me!!

donniekak · Mar 23, 2017

You won't see any direct comparisons between single and twin scroll with the turbo cranked up to choke flow. At choke flow with housings sized to produce the same peak power the twin scroll benefits aren't as great. Twin scroll works best with turbo operation in high efficiency areas of the map.
