faster spooling turbo?

[danielkile]

I am currently running an hx35 and im looking to find something that is around the same size and can make 500+ hp but spool a little faster, price isnt really an issue just looking for a good fast spooling turbo. let me know what you guys think. (I have the extream psi hotside on it)

 

[TofastForU_99]

My sentiments precisely.



I would be shocked if he could get even a 12cm2 housing on stock cams to spool that turbo any faster than the bolt on he already has.

Back when I had the 59mm S200sx in the bolt on housing (74/64 turbine mind you) it spooled similar if not identical to a Greddy 18G I had some years ago. That was with a relatively big cam as well. Now a 56-58mm HX35 with a smaller turbine in what is basically the same housing should easily out-spool that.

He does have junk BC cams though, maybe his problem is they are not dead nuts on to begin with.. which is where the cam gears recommendation is coming from.

So if he's exhausted all the other options listed.. maybe he should just downshift

Or by some folks logic.. a T25 and a 250 shot.. Hope you have some 20lb bottles on hand.

As far as I have seen, the stock 12cm2 housings have a way better powerband than the bolt-on setups. I ran a 7-blade HX35 in twin-scroll form on my Evo and it was awesome on the street.

A 1.25 runner manifold and a 7-blade HX35 in a 12cm2 housing is about as fast as a 500whp turbo is capable of spooling this side of an EFR.

Does the OP have a 7 or 8-blade HX35?

Has anyone done a compound turbo setup on a 4g63 yet? I know it has potential on the 2JZ 6cyl but not sure if it is useless on a 4 banger. Sorry to drift off topic but the faster spooling made me think about the peak of the turbo which made me think about the length of the power band of the turbo.

Surprised it took so long for anyone to mention compounding.

Yep, viperlp just made a record run on a compound auto setup. Plenty of others have done it

Wow now my use of logic is in question because I asked to learn you are amazing.

DIY Nitrous Oxide (N2O) Injection and Turbo Engines n20 increases exhaust rate, do not know where 250 shot came from, I think he is taking it to extremes in an attempt at being funny. I truly was looking to find out why this wouldn't help the op as long as it was done legally. Seeing as 500hp cannot be fully utilized on public roads legally I made a few assumptions I ###### shouldn't have. OP I hope you find a route that works for your goal good day!

Basically what Hal said.

My last combo was moving 65-67lbs/min @ 38psi regularly on the street. 2nd gear getting on the highway was a blast, and it made for easier over-taking.

The 250shot suggesting was because the T25 will tap out just north of 250 whp, and to make the 500whp + requirement listed by the OP that would be whats required..

If you were looking to learn you should get acquainted with the search feature.

You don't have a ####ing clue what you're talking about.

Making blanket statements like this.

My car makes 500hp @ 70mph.

That's certainly a legal speed on some the roads around here, so accelerating to that speed while entering the freeway is a legal use of 500hp.

Do yourself a favor, stop posting and start searching.

The knowledge you seek can be gleaned with a little effort on your part.

Actually I do, your not talking about crusing at 70mhp making 500hp, you are talking about hard acceleration for that power. I would love you to do this while any officer is around, you would fall under more than a few laws broken. Aggressive/recklace driving to start with and if I assume you are in Colorado as your profile shows you can be reported by any driver as an aggresive driver on the CHP hotline.

(2) (a) Except as otherwise provided in subsection (4) of this section, it is unlawful for a person to knowingly engage in a speed exhibition on a highway.
(b) For purposes of this section, “speed exhibition” means the operation of a motor vehicle to present a display of speed or power. “Speed exhibition” includes, but is not limited to, squealing the tires of a motor vehicle while it is stationary or in motion, rapid acceleration, rapid swerving or weaving in and out of traffic, producing smoke from tire slippage, or leaving visible tire acceleration marks on the surface of the highway or ground.

From the code DOT. All states are similar in code FYI

I stand by my Legally statement I made earlier.

The combo used here was the extreme (t25) for an attemt at humor... below is a "search" of a more realistic example of the combo thanks again tho for making this day entertaining at the least.

The TD06/20G is a great option. I can build one for you if you wish. The T3 76 trim Turbine Wheel with a T4 57 trim compressor or 60-1 compressor is also an excellent choice. One of the Holset's problems with spool up is that the turbine wheel is pretty heavy. You could go to a smaller A/R rating on your turbine housing as well to help spool up. Check out "Switchblade Turbo at Motorhead Garage" on YouTube. It is extremely advanced technology.

Actually I do

Actually you don't

You are assuming that it's not possible to put 500 to the wheels without breaking the law, when it most certainly is. Passing, especially up hill, is a great example.

Uphill, full throttle, 70mph is 500 hp. Do that in a 65mph zone (where normal traffic flow is normally 75 anyway) and you're not going to get a citation for anything. Never mind doing it legally where the posted speed limit is 70+ or higher (say some of the two lane highways in the Texas panhandle).

You assume that it can't be done without breaking the law in some way, when in reality the law is based upon HOW YOU DRIVE not how much power you are making while doing it.

So again, you make assumptions without having any real basis in fact.

Who really gives a shit, these cars with 195-210 horsepower will do WELL past the speed limit and accelerate faster than what most would feel safe driving around a cop.

And now your being ridiculous it is up to the interpretation of the officer

For purposes of this section, "speed exhibition" means the operation of a motor vehicle to present a display of speed or power. "Speed exhibition" includes, but is not limited to

There are assumptions on your end as well, perfect weather, no tire slipping up hill at WOT with the hp to weight ratio you have at 500hp by 70mhp c'mon.....

I will not even to pretend to be as specific as you would need to be to make this fool proof, especially since now to most of this thread we both look ridiculous.... I stand by my statement of LEGALLY and will not entertain any more rediculous specifics the point stands up hill, down hill, forwards or backwards using a potential 500hp at once in our cars most likely will not be legal with the exception of some far off lunar alignment that blinds the cop maybe .

And you've been off topic for most of your posts in here. Everyone needs to stop the arguing back and forth and stick to the topic. Another warning will be handed out if this continues.

Do you mean sequential or compound? Sequential will suffer as the motor is so small to start with. Compound like the Mazda Sky-Activ diesel would probably work quite well.

 

[Kokomoguy30]

I have an hx35 with the bep bolt on .55 a/r housing and in 3rd gear I can hit 30 psi by 3500 rpm. It's not as fast as my e316g, 20psi at 2700 rpm, but that is the price you pay for 500 hp over 350-375 hp.

 

[Archer Fabrications]

Fast spool? 500hp? Sounds like you have an awesome turbo for the job. The only thing it sounds like you need is a driver mod. When lag persists, downshift and haul! Legally, illegally, whichever pleases you most doesn't matter to me.

On a separate note. A twin scroll setup also sounds like it would get things spinning quicker for you. Me on the other hand. My hx40 spools 28 psi ( around 59lb a min give or take) is seen by 4300, with the new BEP .70AR t3 set up I'm actually expecting to see a quicker spool at the same boost level, hopefully 4k flat or 4200 even would be nice. Lag is great though! It gives you great gas milage when you just wanna cruise. Plus there is honestly nothing better than hearing your turbo spool up before your waste gate opens screaming at you and your hauling ass at 4.3k+ 4300 is pretty good for full boost especially since stock rev
Limit is 7500
If you want t-25 spool, guess what use a t-25. They are 1,200 dollars new from the mitsu dealer. Thats what i was quoted when i first bought my car in 2011 anyway. Ha like that would ever happen.

 

[swifteagle]

You could get a hx82 .

 

[Archer Fabrications]

Da fuq? How is that even relevant? Do you know how effin big that turbo is? It's like the surface area of the whole 4g63 with an intake manifold. You think THAT will spool fast?

My uncles boom truck has that turbo and it's literally like 3 or 4 of my head big.

 

[swifteagle]

It was a joke.

 

[GDNF2ET]

Although an HTA3076 is an expensive turbo if purchased new, it will do everything you want..Defiantly cheaper and less work than a 2.3 build....

 

[jimblay]

The HX35 is widely-known as being the fastest-spooling and least-expensive turbo capable of 500-550whp with the proper supporting mods.


I'm not sure what you're seeking here, but you can't have a 500+hp turbo that spools like a 16G....it just doesn't exist. You can spend more money for something ball bearing and you may get quicker spool or boost recovery, but you're not going to gain any real airflow and the price is ridiculous. You can also drop down to a smaller platform running a TD05H turbine, but then you're limited to power output as I don't know of any TD05H turbos that are 500hp-capable.

You're at a crossroad of dealing with what you have, spending more money to gain spool but not gain any power, and downsizing to get some spool back but make less total airflow.
