How much difference in Spool Time

[VETTE_50_TH]

So, my plans for this summer includes building a nice 2.0 6 bolt for my new talon, full suspension work, exhaust and fuel setup. The FMIC will be the S/S by ETS. However, the turbo is where im kinda iffy on. I like my evo 3. It spools quick. no problems in entering traffic quickly from a low rpm. But i want something bigger. I've have seen a ton of people talking about the s25x. I've been wanting to get the fp3052 or 3065. But the s25x is cheaper and will put out just as much power. However, before i choose one, how much difference will i see on spool up between my evo3 and these turbos? I would hate to take away that quick city car for a strip monster. I want both. So, tell me what is the difference? Lastly, what is your opinions on the said turbos? Thanks

BTW, the cams will be 272's if that means anything

Roughly 800rpms going by 3000-3200 for full boost on the Evo 3 and 3800-4000 on the 3052.

 

[VETTE_50_TH]

Is that considered a lot? It doesn't seem like much. Gives me 4000 rpm's to play with.

But while that 800 rpm difference, the car is going to pull a hell of a lot harder. Would it be correct to assume that?

[chavez408]

with a much better top end too. What are your goals?

 

[VETTE_50_TH]

a nice 12 sec timeslip, over 400 hp and tq. a street driven, track monster. I want something streetable, its a DD, but able to take to the track and compete at the same time.

the spool difference will not be a big issue one the turbo spools and kicks you in the rear ..

I have an sc63 and I full spool at 4600 in 3rd. about 5k in second and it doesnt bother me to bad.. the car is a monster once its spooled. For a smaller setup like the s256 it will be an awesome daily with plenty of power..

I honestly want a smaller turbo like the s258.. You'll do fine with the s256 its an aswesome turbo.

 

[VETTE_50_TH]

Im guessing you have a t3 or t4 manifold? I think i like the fact that i can use a dsm manifold and its a bolt on. However, i would go to a t3 or t4 if it is worth it. How much power do you get out of your sc 63. BTW, what is the a/r and trim.

Well if you only want a 12 second time slip the evoIII is more then capable of that. Guys are running mid-high 11's with street cars (ie full interior) on pump/meth injection with the evoIII.

As Tyler said the 3052 will add about 800 rpms spool time vs an evoIII, this is what I run & previously ran the evoIII, & I think its an amazing turbo. Being BB you don't really even notice the extra lag, it is much more linear in spool & will start to build boost around the 3000 mark or slightly under. The boost recovery after shifts is basically the same as an evoIII. Last summer I ran 22-24 psi daily & it performed great, I would highly recommend this for a daily driven turbo. For conmparinson the FP30 turbine housing will net you flow resaults comparable to the .63 AR T3 turbine housing.

the spool will not be horrible bro. You can expect a pretty sizeable difference too. Once you get on it that "assing lane" now become a launch pad.

i have a t3... 63 hotside to4e cover.. i made 400awhp on 20psi on a bad tune .. it was a street tuned.. still more tuning to come.. hoping to get a meth kit to get into the efficiancy range of the turbo 25+psi then the power will be

 

[VETTE_50_TH]

Awesome. Thanks guys. I'm leaning towards the s25x or the FP3052. Either or, i could go either way, but thanks for the info. At least im not scared to jump up to the big turbos now

Wow, how things have changed. I remember several years back when I thought, "Wow, that guys running a 20g, thats a huge street setup, I wonder if that will ever spool..... " Now a 3052 or s25X is considered a "quick spooling" street turbo & defently don't consider my turbo to be large.

I was abit worried about lag before I ran my 3052 but with that being said, I can honestly say I have since never once wished I was still running the evoIII on my DD'er. Plus you just can't beat the loudness of dual BB spool, puts a smile on my face everytime I go for a drive

 

[chavez408]

DBB are louder than a regular turbo? i never knew that.

 

[talon187]

ahh im running a 16g now myself and want somthing bigger gives me somthing to look into i may get a 62-1 for cheap so i may go that route but i think ill keep the 16g for the glant vr4 im building as a daily driver

 

[VETTE_50_TH]

Why does the fp3053 look more intimidating than the fp3065?

One of the few factual item in FnF, "Thank goodness for ball bearing turbos".
One thing to remember about the larger turbos is efficiency. 20psi on the GT30 will be much cooler than the EVO3 plus you can way more room before hitting the edge of the map.
Check the recent thread for the folks running 16g, 20g, and GT30. He initially mentions the EVO3 hitting a wall at 20psi and doing nothing but inducing knock after.

I think it's actually the big 4" diameter intake with anti-surge ports that makes them louder. The compressor makes more "noise". I've heard S256 owners say the same thing and they aren't bb.

James

You mean FP3052?
The difference that jumps out at me is the very different way of doing the anti-surge ports in the compressor inlet.

The picture of the fp3065 on the FP website now looks to me like the latest and greatest anti-surge cover like they are using on the GT3582HTA. The anti-surge opening is very thin.
The fp3052 has the same cover that's been used for a long time on the GT3076. I've wondered if they will replace that now with the newer style cover, but as far as I know the older style cover works fine as is (the aggressive looking one).
Hey guess what, I just looked and now FP has a pic for the GT3076HTA showing it with the new style cover. I bet they could sell you the fp3052 however you want it: regular garrett compressor wheel or HTA compressor wheel; older Garrett style cover or the newer HTA style cover. The HTA parts would just add a little to the price.

Gary

As mentioned above I also think the 4" inlet with anti surge is what makes all the noise, all my buddies tell me "Your car sounds mean whats in there a dbb turbo", but its actually an h1e which is comparable to the hx40 and this thing sounds like a truck even when I'm just driving around.

BTW forgot to add you better look into the s2XX or s3XX series turbo's. After some researching you'll realize that this is the way to go, the gt35 is so overrated and most people just slap one on just to say "I got a gt35 in there", the s256 is a perfect street/track turbo and spool up time is crazy fast.

 

[Larry L]

if your looking for big top end power, and not sacraficing spool. I'd suggent going ball bearing. I switched from the B16G to the HX-35, and the lag bothered me for some time. However, I have learned to compensate, and the huge gains up top has me quite amexiac about the whole lag issue... What were we talking about again???

 

[dsmmike50t]

I actually jumped from a hybrid 20g(frankenstein stage 3 turbo) to the h1e(hx40) and haven't noticed any difference in spool up time. Someone on here once mentioned that the s256 spools up faster than the gt35 is that true.

 

[Burnett03]

What compression ratio do you plan on running? That will determine your spool up also.

 

[VETTE_50_TH]

8.3:1 Man this thread went wild after i stopped posting in it.

Im having so many hard decisions to make right now. I dont know whether to get a fp3052, s2xx or gt35r. I just want a good turbo thats good on the street and track. I have a evo III now, and i love how quickly it spools, and the power i get from it. I just want more. Also, cost is a factor. I would spend 2400 for the whole outfit for the forced performance stuff. But if i dont have to spend that much, i wont.

I went from an EVOIII GT 16g to a full garrett t3/t4 50 trim and I have to say that the difference is noticable...at first. I was going from full boost at 3300 rpm to full boost right over 4000rpm. Once I started driving it though I totally forget about it because it is so much more fun to drive, the power increase is very nice and it holds boost all the way to redline and then some. I have to say that my 50 trim is my favorite turbo so far, and I drive my care daily btw.

mmmmm s256 +1
