question about a 50trim setup

[turboblack2door]

i would like to do a 50trim setup on my spyder. Right now i have a 255 fp, greddy SP2 exhaust and greddy type s bov a greddy hard pipe kit, Would I be ok using the stock injectors and what kind of power could i look to put down at the wheels if i was only going to push about 10lbs?

 

[xxShaneOmac]

If you only push 10 lbs, (I dont even know if the interal gated 50 trims are set up to run such low ammounts of boost) you should be ok for stock injectors. Power is something you will see when you dyno your car there are to many defining factors to tell you xxx power.

But jump on the fuel and a tuning device asap to really wake up the 50 trims capablitys.

10 lbs would still be too much from a 50 trim on stock injectors, you might get away with it but its pushing way to much air for 450's to support it. Plus only running 10 lbs on a 50 trim is almost senseless, you would see greater results with a 16g at that boost level, its way out of a 50 trims effeciency range. If i were you id get a set of 650's and an SAFC, run 20 lbs and call it a day. You should expect to see high 300 whp numbers at that level.

how reliable would that be with the stock 7bolt?

 

[1992awdlaser]

Look at the mods in my profile. My car is pretty reliable (I have a 6 bolt though). My parts are a very good setup for a 50 trim.

 

[turboblack2door]

would an afc be good enough to tune on?

What exactly are you looking to get out of your 50 trim? Yes, an AFC will be able to compensate for 650s, but that's as big of an injector as you're really going to be able to reliably use. As stated above, if you're planning on keeping your fuel system basically stock, a 50 trim isn't really for you. Also, you're going to be needing an AFPR for that 255

You NEED an AFPR and to have your pump hardwired to start with(look on the VFAQ Site - Visual Frequently Answered Questions to see how to wire the pump). Also, the airflow and the way it comes on is going to change so dramatically that you are going to need something to tune with. I recommend DSMlink, even for a begginer, it's great. but an AFC +680cc's whould let you extract some good power out of it. just make sure you at least have some way to log and count you knock. Even though the stock knock sensor is very "dramatic" abotu things, it WILL SAVE YOUR MOTOR!

But honestly the cost of a logger + SAFC will get you close to buying DSMlink, just save a few hundred more and get the right stuff the first time!

10psi on a 50 trim will work just fine on stock fuel. It will also, more than likely, be as slow as stock.

First decide what kind of power you're looking for and then pick a turbo. With that in mind, what kind of power are you looking for?

 

[turboblack2door]

i was only thinking of that low of boost for stock fuel. Once i get some injectors i would turn the boost up I'm looking to put down around 300whp

 

[jaday]

To be honest with you, if you're just wanting 300, a Evo III 16g would work really well for you. By all means you can pick up a 50 and reach the 300 hp mark with the proper supporting mods, but if I were you, I wouldn't rule out the 16g.

As far as the fuel, the people above are right, just keep the boost as low as your wastegate will allow. Don't push it until you can get some bigger injectors.

 

[turboblack2door]

i'm talking about 300 at the wheels

 

[1992awdlaser]

A 16g will do that. But if you plan on upgrading later I would get the 50 trim

 

[c4uldr0n]

I know that my 50 trim is a blast after say 18psi. I maxed my 650cc injectors out at 20psi with the 50 trim or atleast to the point I didn't want to turn the boost up any more.

^How did you max out 650's at only 20psi? How much power could you possibly have been making at only 20psi? Do you have a stroker with cams? 650's are easily good for 400whp.

A 16g will do that. But if you plan on upgrading later I would get the 50 trim

haha! Where's the Honda-Tech hammer smilie when I need it?

OP, good look at the EVOIII 16G dyno number thread, laugh a lot at all the 250-270whp numbers, and then go buy the 50 trim. That turbo is working far too hard at 300hp and has a pretty useless powerband unless you like shifting early.

A 50 trim is perfect for 300hp. If you're going with an external gate (which is a very good idea), make sure you get a low enough PSI spring to be safe on your stock injectors.

A properly set up 16g car will have no problem making 300 whp. A 50 trim isn't "perfect" for 300whp. This is because it is not even close to being used yet. The 16g is a good 300 whp turbo. Don't blame it on other people that don't have the car setup or tuned correctly.

Have you seen the dyno thread? The average 16g is making around 280awhp.

A properly maxed out 16g will make 300whp, maybe even low 300's with cams. The powerband will also be useless and falling off in the rev range when you need it to be climbing.

Don't size turbos by their maximum flow. You don't want a 300hp turbo for 300hp, you want a 400hp turbo for 300hp. Overworking your turbo FTL.

35lbs/min is ~350bhp (less on a crappy ultra-low compression 4G63), so that's right around 300awhp. Looks great to me.

 

[1992awdlaser]

35lb/min? Mine is rated at 48 or 49 lb/min. And you want as small as a possible turbo to make your goals so you spool fast. The 50 trim is capable of 500whp from what I have seen not only 400. I am pretty sure mine would be over 400 actually. Have you seen the thread of the tpg guys making 460 whp on a 16g? I'm not saying that everybody is going to, but making 300whp isn't that hard on a 16g and your NOT maxing it out at that level. Hell, you don't even need cams to make that on a 16g.

I don't care about that thread or what people have done. I KNOW what a 16g can do by being setup correctly.

Wrong. You want the turbo that will make the most power in the RPM range where you'll be using it the most. What good does full boost at 2,500rpm do for you when you'll never see that RPM during a race? Meanwhile, you're sacrificing higher RPM power that you do need in the name of "fast spool".

If you actually need to flow 48-49lbs/min I'd suggest you find a bigger turbo than a 50 trim. There is no need to run turbos at or near there maximum rated power. You're only hurting yourself.

Oh, and for the record, my 50 trim spools a whopping 200rpm later than my Evo 16g did and transient response it actually better.

500whp is pushing a 50 trim waaaaay too far. It's a 300-400whp turbo. Yes, it CAN do more power. But why would you want to? Get a turbo that's actually meant to do the amount of power you want. I shouldn't be running a 50 trim myself, but I can't justify spending over $1,200 on a 35R.

460hp on a 16g? LAWL It's a 250whp turbo that people have taken much too far for reasons unbeknow to the rest of the world.

250hp...are you serious...WTF. 400hp on a E316G is maxed. So it is a comfortable 350whp turbo with the proper supporting mods.

Right right. Of course it is. That's why there's so many people making 350whp on E16g's.

I'll give the compressor a comfortable 300whp, but the hot side is laughably small. It's simply not appropriate for 300whp and over. CAN be done and SHOULD be done are worlds apart.

 

[turboglenn]

I've heard the 57 trim surges a lot on our cars, but i've never experienced it even on a astock long block at 28psi. What kinda of surging are we talking about? light, heavy..car shuttering or just a sound of air backing and releasing repeatedly?

If there was a cover to relieve teh surge ona 57 trim, although it's a bit of a lazy wheel, it has very nice hP potential, it's just that it's left line is very oddly shaped making for weird points of surge and choke at different pressure ratios

How does the 60-1 compare? I'm not trying to thread jack, but my ultimate goal is ~450-460 ..no less when maxed out, but i want the fastes spool possible and not have to run 30 psi to get it.. i'd like to make it in the 26-28 range tops.. there's so many new turbos that are the weird "new comers" since i took my aprenticeship and i'm very interested in them..

can anyone PM me or answer here about a turbo suitable for that i decribed above that would have hte fastest spool possible without breaking the bank..it it's too much i'm either downsizint to a 50 trim or up to a 60-1 or 60-2..... I love my 57 as it has great range and power output... i'd just like a bit of an "attitiude change" in the way she comes on. I think this tubro would be awesome for a 2.3 or 2.4 swtroker though. With the added exhaust for spool and the flow of the turbo it could be a very powerfull combo!
