Who has one? How do you like it? Where does it spool in at?

thanks!

Mr.DC2TurBo

dont get it unless you have a ls/vtec or you plan on reving pass 7K rpm. By the time you hit full boost ~5K rpm you got to shift again. Very good power but tooooooooooooooooooooo much lag.

i though these sc61's are know for spooling up relatively fast???!!

I think you heard wrong. In general the larger the turbo the larger the lag. But the power of the sc61 is uncomprimised! Just search for member b18cx and look at his numbers!

Lag time depends in part which version of the SC61 you get. We make these with three different tubine wheels for different sized engines as follows:

2.0L and under - T350 76 trim exhaust wheel - 630 hp
2.0L to 3.0L - T04 69 trim - 650 hp
3.0L and up - T04 76 trim - 680 hp

A lot of people select the biggest SC61 because they're all priced the same and they want the big hp numbers when really they're probably better off with a smaller turbo. It's all in choosing the right combination.

SC34 on stock LS with Hondata and 550cc injectors.



SC61 on stock LS with Hondata, GEM blockguard and 660cc injectors.



There are allot of variables too. Wheel trims, compressor cover, manifold, downpipe size, exhaust pipe size, tuning, fuel, weather conditions, etc. Just a general comparison above.

i have an sc61 on my ls turbo set up.....it does have its pros and cons.......yes it does spool slow...for me around 4200 to 4500...but once it starts..it doesnt stop.....once spooled, its like a hhuge rush......top end is amazing!......ive had the sc34 and the sc61....if i was u ..i would get the sc34 or the sc50....the sc61 in my opinion is better built set ups...it seems to be more effecient.....ive had it on fully built ls and compltely stock ls.......i would rather have my sc34 right now on my set up right now.....but either way i have no complaints.....

0x64 on that sc61 dyno what psi of boost is it set at?

Rod Short

You're all over it. I was trying to say that lag time depends, in part, on . . . Throw in inlet flange size and A/R and you probably got all the bases covered.

Mr. Softee

unless you are making above 350whp don't get the sc61... imho.

I couldnt agree more.

T3 is good for under 325-350whp.

what r the main differences between having a sc34/sc50 on the LS? spool time? I was looking into the sc61, but after this post i might be swayed to either the 34/50. Can anyone comment more on these 2 and how they are on an LS?

SiRkid

so you reach full boost at 4500 OR you start to spool at 4500?

RedTegLS

Being that the LS redlines 1000 rpms sooner than a GSR the sc34 seems like a more reasonable sized turbo. Quicker spool time is very cool becuase its more useable power on the street. It would be cool to have one that kicks your *** at like 4400 rpms though. Just an opinion.......

nevin

it really isnt that bad

Mr. Softee

it might not be 'that bad' but why pay more for less. By this I mean you are paying $700 for a turbo that isn't efficient for under 300whp. You will lose midrange and have a slower spool up, but you will have the sc61 BLING factor. A smaller t3/t4e is much more suitable for under 350whp as it is much more efficient at lower flow levels and thus produces much more midrange power. A broad powerband is obviously ideal, and having an LS motor basically essential or you will drop to low power levels when shifting.

I couldnt agree more. People are just buying these turbos that dont fit their cars. no reason you need a 400whp+ T3/t4 on your 200whp sohc. That is why people use T3's. A friend of mine just made 210+whp and 180-190wtq (i forget the exact numbers) on his Z6 at 10psi w/ uberdata and a T3 .48/.60. You dont need a T3/t4 or a ghey precision to make power. you need the right turbo for your setup. that is why he made such killer numbers.

So what would be a straight turbocharger?

Straight T3, of course.

So would a T4 be bi or straight

its ghey, not gay, big difference buddy. Anyway precision turbos will be a waste of money until i see 1 legit dyno graph showing with the exact same setup they make more power or atleast the spool times change

I agree if you building a "junkyard" based setup. But if your building something with power, You can't beat an SC61 for the price. find another turbo for &lt;$700 that has teh ability to make insane power while still being effiecent @ low boost levels.

lend your great advice somewhere else.

Precision turbo's have been well proven. There are so many dynos already posted.

How about you find me a dyno of a t3/to4e garrett or turbonetics that will prove your point

b18cx's car made 320 whp at 9 lbs with sc61 and stock jdm b18c

those are vtec motors but you get the point.
