I've done some research but still can't really come up with any difference besides the wheels. Can anyone else give me anymore insight. Both with same trims and all. What I'm looking for is a turbo that can make some good power and lower boost leves. I would love to make over 400 runnning under 15psi.

 

as far as i know (i spoke to rod about it this past week). the only main difference is the GT turbine wheels. interms of real world comparisons... he told me that inlinepro switched to one (i think from an SC61) and spoolup was pretty much the same but they picked up 50hp.

 

Wow thats not bad for and extra 50hp. I've found that there is only about $100.00 difference between the two. Anymore

 

yah. i was considering upgrading hehe.

 

U wouldn't happen to know how much boost they were running do u

 

nah. if you want just call up precision and speak to rod. he's a cool guy, very easy to talk to and is always glad to help whenever he's not busy

to rod

 

Just in case you guys might be looking for a GT35E. I have on for sale. Here's the link. https://honda-tech.com/zerothread?id=920822

 

Yeah I would def agree with that, I've talked to him a couple times by email.

 

thats a damn good deal.

 

ttt

 

GT35S unless you want to bone up and go for the GT35R! If you are looking for more hp at lower boost than the GT series are gonna get you just that.

 

thanks homie

 

i vote the gt35s ...

 

i think for max power the sc61 will own... the t350 or t4 turbine housing is where its at

They picked up 15hp, not 50hp.

How do you figure? the GT35 84 trim turbine wheel flows more volume and is more efficient then the T350 turbine wheel.

thanks for the correction ... i probably just heard him wrong lol

have you ever put a gt35r and a t350 sc61 side by side...... the t350 turbine housing is way bigger than the gt35r turbine... all a more efficent turbine wheel means is less lag

i'm not smart but i wouldn't think that efficient ONLY means less lag. doesn't the turbine wheel also aid in power? when i say that i mean better designed, less restrictive wheel would create more power. it makes sense to me because hell even the sc61 is rated based on the turbine wheel... T350 SC61 ~630hp, 69 trim T04 ~650hp, T04 P-trim ~680hp.

Have you seen the flow #'s for the two wheels?

 

on precisions website all the sc61's are rated for the same 680hp

and its not the turbines alone that limit power... hell the sc50 has the same turbine specs as the sc44 and the sc60. the sc61 has a bigger housing and a bigger wheel. i have had the 2 side by side, both apart and the differences in the turbine wheels are minimal at best, the have close to the same shape, the gt35 is a touch smaller... the biggest difference is the turbine housing... anyway you cut it a t350 housing flows more than a t3 housing.... thats like saying a 1 inch hose will flow as much water as a 2 inch hose.

the compressors are the same between the 2 turbos, hell if the bolt holes were in the right spot you could swap the compressor covers.

 

the site must be wrong then... or maybe just an advertising ploy. rod himself told me that the differences in turbine wheels determined the power output on the SC61's. Yes they (SC50, 44, and 60) have the same turbine wheels but obviously different compressor wheels (50 trim vs 60 trim vs 60-1). The base SC61 has the same E housing as all the other turbos with the GT35R compressor wheel. T350 refers to the wheel as far as I know...
T31 69 trim = stage 2 wheel
T31 76 trim = stage 3 wheel
T350 76 trim = stage 5 wheel

so a T350 housing vs a T31 housing (i'm assuming that's what you meant by T3 housing)... the T350 would be a little bigger because of the bigger wheel.



SC61 on left, SC60 on right... T350 vs T31, both are .63 a/r T3 housings

 

I'm just wondering, if the sc61 is so much better why does the gt35 make better power at lower boost. Yeah if you were to peak out the turbos the s61 would win but I'm not looking to peak it out I just want to make good power at lower rpms and lower boost levels and it seems that the gt35 would be the better one for this

my guess is that turbine wheel. just because it's smaller doesn't mean it's not as good. it's probably more efficient than a T350 wheel... who knows. and efficiency can be better than all out power or size right?

 

we arent talking about low boost, we are talking max power. of course a smaller turbo (when compared to one thats too big) will make better power on low boost. that and the dual ball berings dont hurt either.

for max power, my money is on the sc61, for a normal car.. the gt35r would probably be better just because it will spool alot faster and both these turbos should be good for low 10sec power.

 

this is some really good info for both.
