AGP 60-1 turbo spools 30 psi @ 4000 rpm

[bigfoot]

You guy's need to see this thread. Would this thing surge on a 2.4?

I think 30lbs by 4k with a ball bearing center section AND a stanadlone is feasible. You guys wouldn’t believe how much faster you can spool a turbo with a stanadlone.

It would be dumb to put a bolt on turbo on a 2.4. Get the Garret version or just go full T4. I see about 30lbs by 4k on my 2.4L but my turbo has a 82ar exhaust housing. The 2.4 BEGS for a big turbo. At this point my BR57 would be the absolute smallest turbo I would put on. A GT56 or something in full T4 would be the best choice if you wanted all out power.

Yes the bolt on is just too small on the 2.4. If you spool a 60-1 below 4000, it will surge. The .82 60-1 is the absolute smallest for the 2.4. The 2.4 just screams for a TO4R. But the 56/stg5(.82 a/r) would also be very good.

T04R..... hehe... My bank account screams when I say T04R.. :laugh:

That's incorrect.

that is a vague statement,,,




help us out... don't leave us hanging...

That's incorrect.

Actually that's quite wordy for Kevin. He isn't always so talkative.

To say that compressor X will surge if it reaches Y boost before Z RPM is incorrect.
X compressor will surge if it reaches Y boost before Z airmass. You do NOT always have the same airmass at 4000 RPM. A million different parts effect how much air your eninge can consume at 4000RPM.

That's incorrect. Probably only like 10,000 parts.

I understand...

you would need to bring in the factors of A valve size/material, B CFM rates per port, C velocity of aforementioned CFM... etc... I didn't think of it that way... thanks for clearing that up...

You are right Kevin. Im sorry. I should have explained it better. From my experience, I have found that larger compressor wheels, on higher compression, larger displacement engines, will surge if the wheel is spooled too quickly. I guarentee that if rdrkt was to put a larger compressor wheel bolt on on his 9.0cr, 2.4, it would surge itself to death.

But your explanation both sounds better, and is absolutely correct.

so with all the given information ...what would be a good high HP decent spooling( full boost @~ 4k rpm) turbo for a 2.4l block?

I myself am building a hybrid motor and was thinking about a

t3/t04e 60-1 compressor wheel stg 3 exhaust wheel with a .63 a/r exhaust housing

 

[Black95TSIawd]

wouldnt that be too small for a 2.4. I'm not too familiar with those setups but i "think" that would be too small

I don't know that's why I am asking.

 

[Rick@AP]

I personally would not put a t3/t4 on a 2.4L. I think its too small. With the correct supporting mods I would probably do a straight t4 either a 60-1 (don't really like these a whole lot but they work) or a t61 with a small exhaust housing (my top choice).

 

[swordfish]

I agree. You should look into a full T4 for a 2.4L. If you are worried about clearing the DP with a full T4 and really want a T3/T4 so you can just bolt up a DP, then use the T350 turbine wheel in an .82 AR.

A 60-1 t3/t4 with a stage 3 wheel and .82 A/R turbine housing works absolutely awesome on a 2.4L. Provided the car is setup well and tuned well you will have full boost well before 4000rpm. The .63 would be too small. Engine displacement and turbine housing A/R go hand in hand. The t3/t4 makes for a killer street strip setup. If you are after ultimate power capability and willing to do a little fabrication then step up to a straight T4. The new 56trim compressor wheel would probably be an even better choice for the 2.4 though along with alittle more turbine wheel than the stage 3.

 

[mlopez]

My buddy has a full t4 on his 2.4 and it works just fine. Don't know the specs on the turbo but I know its a full t4. It spools up around 3900-4000rpm range.

 

[talonted_one]

thanks guys...I would love to put a full T4 on my car but I dont think money retrictions would allow me to do that but I will look into it I have a new turbo hook up so thinkgs might change.

so for now a 60-1 t3/t4 with a stage 3 wheel and .82 A/R turbine housing will do me fine. maybe next year I will step up.


thanks again

Full t4 isn't that much more, if any than a t3/t4 so whats the issue? Call AGP and get some pricing.

 

[talonted_one]

see the thing is ...I already have a T3/T04E 57trim . 48AR I figured since I need a rebuild and I no longer have a 2.0 I should upgrade.

Besides I like the idea of having 30psi at around 4k rpm. The car will still be a daily driver( don't worry I have 2 more turbo DSMs just in case )
