For a B16A2 with stock internals so far, and the redline set at say 8200, will the SC34 pull all they till redline or will it come up short? Thanks

JGurr81

the way* not they sorry

JGurr81

If it doesn't which Precision next in line would pull till redline but also make boost by ATLEAST 4200, 4000 would be nice though(if there is no turbo thats hits full boost at those rpm's and pull till redline, then just let me know and the thread will be no more haha)

It will probably pull to redline np. Your just going to have to use higher boost #'s to make big power #'s, but it's no big deal, that's what happens when the turbo is correctly matched to the motor. You will be rewarded with fast spool and a natural powerband.

When in doubt, look to greddy (at their turbo sizing). They pick some of the best matched turbo's possible for the given applications.

The Shodan

True dat, however, he would definately have to look at the compressor maps and compare size housings, turbines, etc. Since Mitsubishi Heavy Industries uses different sizing numbers

The SC34 should be alright to redline. From what I recall from the Choke Area of the compressor map, you should be fine to redline at about 640cfm... That should work fine for you

If your looking toreach full boost around 4200 rpm then this turbo is perfect for you IMO. I have the sc34 on my ls motor, full boost around 4100 (8psi),3" exhuast.
It pulls hard until redline, I dont feel any drop off in high rpm

sc34 is by no means a "small" turbo, people just get too brainwashed by the sc61

the sc34 is a good match for your application and redline.

The Sc34 is a medium sized turbo, it is by no means a slacker.

What's the SC44 spool like?

JGurr81

Also whats the spool time with a SC-61 w/ a lightened flywheel? Thanks

The 34 is not a small turbo. We are not talking about eclipse turbos or something here that max out before redline. You can rev ur b16 to 9k rpm all day long w/ an SC34 and have a beutiful powercurve to go w/ it.. The SC34 is efficient up to about 450whp this is not a small turbo.

Let's see some compressor and turbine maps.
Everything else is just B.S.
Have you considered garrett GT line of turbos?
They have all their maps in their online catalog.
You can plot your airflow on them and see how it looks. Something like a gt28R might look great for your engine. Not only is it small, it's also cartridge ballbearing which would spool you up about 15% faster AND produce more power by reducing friction. Don't let the small size put you off before you look at the maps i hear it blows very well too.

Im not sayin its a small turbo its just that if i can get similar spool times with a flywheel and a SC-61 then I would rather go with that but if i get good power across the whole band and theres like more than a 1K difference in spool up times then I would go with the SC-34, but stiill interested in what the SC44 spools like in comparrison to the SC-34

TurboJesse

how much power do you want to make?

JGurr81

i want to make atleast 300whp....I'm thinking about getting the lovefab sidewinder so it would help me with spool times but id have to raise a little bit more money. Keep in mind im gonna have this car for a while and want to make a "project" out of it and eventually get 400+ or maybe even 500+ in the future...not near future but future(1 year or 2) The SC-61 appeals to me because I will then never have to switch my turbo, and w/ a flywheel i was told it could spool similar to the SC-34...

TurboJesse

i would stick with the sc34 for now, you could still do 400+ with it...an sc61 will get annoying waiting for the power on the street with a stock b16a.

The SC34 will spool about 500-600 rpm's faster then the SC61... The SC61 uses a larger compressor wheel and a larger exhaust wheel, a T350 instead of a T31.. The SC44 will spool about the same as the 34, maybe 100-200 rpm's more lag.. It uses the same exhaust side as the 34 but has a slightly larger compressor wheel.

A lightwieght flywheel is not going to change the RPM ur turbo spools at, it will only get u to that RPM faster.. Same thing happens when u go into a lower gear.

I don't really think the sidewinder is gonna help w/ spool times.. There are no back to back comparison's that show any proof of this..

Basically if u go w/ the SC61 you will have potential for 500+ later down the road.. You said it will be a year or two before you would want power like that... In 2 yrs your prolly going to want to replace the turbo you get today because im sure it is going to get some abuse and mileage in the next yr or two..

Today u need to decide how much power u want, how much boost u wanna use to get there, and how quick of spool up do u want.. The 34 will take about 10-11psi to make 300whp.. It will spool app. 500 rpm's faster and has potential for 400+. The 61 will take about 8-9psi to make 300whp. You get 500 rpm's more lag and potential for 500+... Its all a big trade off and you won't be dissapointed w/ either of them.

JGurr81

Well i know the flywheel isn't going to change the rpm it gets at butr yea it would get there faster which is why i kinda wanna go with the SC61

thats makes no sense and i hope that isn't your sole reason for justifing teh sc61

JGurr81

A lightwieght flywheel is not going to change the RPM ur turbo spools at, it will only get u to that RPM faster.. Same thing happens when u go into a lower gear. &lt;---posted by DIRep....thats pretty much what I said how does it not make sense?? No thats not my sole reason for choosing the SC-61 others are that I think that it will be a better turbo in the long run, more efficient, less money in the end, same price as the SC-34....now somewhere i heard that Rev Hard now sells their kits with the SC-34...if this is the case then no i would not probably not upgrade to the 61 unless it however is free.

My sc61 pulls all the way to redline. This is dangerous, but even in fifth gear. I topped out very fast without even realizing i was topping out. I still like the sc61 out of the both. You have to just know what kind of power you want.

JGurr81

Well i know the SC-61 will pull to redline, and by the replies the SC-34 will too just that the SC-61 flows better and makes more numbers. And because i will be constantly building my block/head I think the SC-61 will be better for me because i wont have to swap out turbos/ unless i just trahs this one and have to buy a new one. Oh eyah to the comment about the sidewinder improving spool up times...i dont think the manifold ITSELF improves the spool up time, but the sidewinder allows you to run a 3" downpipe in conjunction with your A/C and besides custom i haven't heard of or found one that could do that yet, besides custom. Oh yea I know fullrace has one now but its pricey!!!

TurboJesse

there both good turbo's, i just think an sc34 has a more useable powerband, especially on a stock bore, stock internal b16a, i run a garrett t3/t04e 60 trim .63ar and the lag gets to me sometimes, i personally think for the year or 2 that you will have your stock engine you will be happier with the sc34...
