60-1 Spool up & Driveability

[camman420]

Im going to be getting my motor built at the end of the summer and my turbo just went out on my car...The issue is I was planning on putting a 60-1 stg3 .63ar turbo on AFTER the motor was built, but now im torn between just trying to find a replacement for a few months or to just go ahead and put it on there. With stock cams and 7.8 compression what kind of spool times am I going to be looking at here? Ive heard that a 60-1 puts out crappy power on pump gas, is this true? BTW I will also have all supporting mods other then fuel (which will go on with turbo) already on the car minus the built engine

On pump gas I would much rather run a 50trim for a 57trim as oppossed to a 60-1.

I ran that turbo on L26 (Nissan OHC6) and it was spooling full boost at 3500rpm on dyno. It's heavier wheel than 50 trim but I was making pretty decent power on pump gas. 12psi it made 253RWHP.

You'd be looking at 20 psi by around 4300 give or take 100rpm. 60-1 is fine on pump gas and even better on race gas, doesn't really come alive until 15+ psi though. And I'd run a beater turbo after you get your engine built, just to be sure the little metal shavings don't douche the oil seals in the 60-1.

I agree with TRBOTSI.

Just get a beater turbo to throw on there for now, rebuild you motor, run the beater then install a good turbo.

I have a T25 laying around that I use. I drove it on my built motor and I would drop off boost at 4K rpms. After I got the motor broke in I switched to a 50 trim.


My $.02.

Agreed

What do you want to use the car for. If you are taking the "Swiss Army" approach street, track, and strip go for the 50 or 57 trim. If you want top end power and you don't mind losing some on the bottom end go for the 60-1. Or if you want both run a 35 shot of Nitrous with the 60-1 and have the sweet bottom-end response when you need it.
Hope that helps. Or at least the third option is what I am gong to do.
Peace.

Im not too concerned about hp on pump gas since I know that a 50 trim is the pump gas king, I just didnt know how bad a 60-1 would be on pump gas until I get the motor built. The reason I was asking is I know things get blown out of proportion really easy and just wanted to get some clarification on how bad a 60-1 REALLY is on pump and not what it hypothetically is.

I've seen street driven FP Red Talon and GVR-4 around here. They are 60-1 right?

The people saying the 60-1 makes such bad power on pump gas probably havent drive a car with the 60-1 in it.

Also the t04e 60-1 will probably spool better than the turbonetics 60-1 with the 4 inch inlet.

I would say if your unsure just buy the 60 trim in the t04e cover.

It will make more top end... and it should be pretty good all around pump gas.

I know a few in CO using 60-1 compressors. They say spool is pretty tolerable, and they drive them daily.

I would, though, go with the 50 trim. It is much more efficient and you will be able to run higher boost on the street when you build the motor, ( I assume you will be running higher than 7.8:1 compression and the better effieciency of the 50 will allow you to run higher boost without knocking.)

If you are worried about not having enough top end, (never heard of someone with a 50 trim saying that), just use a good sized turbine and housing.

Incorrect.

I ran a 12.1117 trap on pump gas with my factory motor on the 60-1. I drove the car everday at that point because it was my only car. Most people here would kill for pump gas numbers like that. I still say that a 50 trim will make more power on pump gas with less lag. My buddy Racegate did something like a 11.7@122 with a green on pump gas in a pretty much full weight 1g. That sounds pretty nice to me.

However a 60-1 is a nice turbo if you don’t mind a bit of a compromise. It will start to make some serious power after 25lbs. Which will more than make up for the bit of extra lag. But most people that say they want to build a track car end up changing their mind.

Well my buddy here went 120 with the 50 trim on pump gas also... he hasn't made any pump gas runs with the 60-1.

I do know that high 120's should be possible with his setup, if he does it on pump gas or c16 really doesn't mean much to me.

BTW I bought his old 50 trim... it is still a great turbo... just not for thoose looking to trap high 120-130's.

I agree, most forums are known for people running their mouths when it comes to a thread where they have no firsthand information pertaining to the subject. BTW, I trapped 117 on pump with my 60-1...at only 20 psi..
