APEXI Si

I am putting together this kit and i am trying to figure out what numbers i can plan on getting.. I would like to make between 180-200whp.

JDM d15b (130hp)
tubular manifold
y8 intake manifold
10lbs
t3. .48hot .42 compressor
intercooled 2.5 inch exhaust.
450cc injectors
hondata s100 with boost

Ps. do you think i should run a bigger turbo. i just don't want to lose power down low

TorganFM

131hp

rjardy

~ 160
bigger turbo

damn.. i thougt it would be more than that.. i made 156 on 10psi with a dsm t25.

kranked91dx

you'll hit 200 easy,
a guy here, with the greedy kiton a d15b put down a +/- 210 hissssshhh P @ like 12 psi, not too shure of the number but it was pretty amazing though!, that's pretty much why I go turbo on my d15b.

keep us updated

you can make 200whp with a t3 easy, you just need to run a good amount of boost. I'd bet 12psi or so would get you there- if not, run more. t3's are efficient until like ~20 somthing lbs on dseries motors if u check the compressor maps

APEXI Si

well maybe i should run a bigger turbo then.. like one from a SVO mustang. those have .60 and .63 ar's..

VTC_CiViC

Run a 60-trim or even a 50-trim T3 and you should see close to 200whp by 10psi.

damn right... 60 trims own on d-series

Jkan2001

should be making some decent power

i made 176/173 on a tiny IHI turbo RHB5 and the apex kit on the AFC hack on 8 psi.

oh yeah this was on a y8 with 2.5" turboback exhaust

CivicSoul

I made 209 hp, semi-tuned at 9 psi on the t3 50 trim, .60 comp, .48 hot

APEXI Si

so what turbos are you guys running... to make that power .. like j-yard turbo or brand name turbos

Sinner

I'm gonna say around 130whp or 160 flywheel at 5psi. I had a similar setup.

Who are you???? Efficient to ~ 20 lbs......No. I think you need to learn how to read compressory maps a little better buddy. Plus, there are 6 different garrett t3's alone. I think the Super 60 may be able to run almost 20 psi....but it would way past its surge limit.

And 130 whp???? If this is what you made with your turbo setup, I'm sorry to hear that. But that doesn't mean thats a normal outcome. Tuned properly with his hondata and running 8 lbs or so should get him about 200 whp.

APEXI Si

do you think that is possible with the .48 turbine and the .42 compressor

DigitalFusion

Here's an ITR with a 40 Trim T3 at 8psi
EDIT: damn pic wont work.. go to this thread:

westcoastcat

i have a b16 and a jdm d15b, which one would be cheaper to turbo, @ like 6-8psi, and what turbos are good for those motor's?

Are you one of thoes people who knows it all and you're always right? LOL, you people bug me. This is going to hurt, but here are some facts. Goto: http://www.turbofast.com.au/FlowT3.html and look at all the popular T3 compressor flow maps. Now realize that a pressure ratio (those are the numbers on the Y colum LOL) of 2.3 is 20 psi at sea level. Notice that every compressor has at least part of a 70% efficency island above that point? A 70% efficiency island is a perfectly acceptable number to shoot for when designing a turbo car. Now, you will have to choose a bigger compressor to flow as efficently at higher CFM (or more accuratley lbs/min) levels.

Thankyou for your time.


EDIT: One final thing, you have absoutley no clue what a surge limt is do you bwhahahaha.

I'm building a similar setup (and I know how to read compressor maps). I decided on the "Garrett TB0344" (Merkur 85-88 XR4Ti +Watercooled center) turbo to stay in the higher efficiency at the upper rpms. I think if you find one at the boneyard it won't be watercooled though (I may be wrong). I'm shooting for ~200hp at 8-10psi on a bone stock z6. I went with the .48 turbine side A/R like was found in the auto tranny T-birds to help spool time.

Hey danl....I don't think I know jack **** compared to a lot of people.....but guess what? When it comes to compressor maps, I obviously know more than you. Just because there is an area on the map that corresponds with the 2.3 pressure ratio does not mean ANYTHING!!!!! Do you know what the x axis represents? I don't think you do. For a turbo to be efficient at a certain boost level, it has to be so at certain flow rates (x axis.) Do you know how many lbs/in a d16 flows at 20 psi at 3000, 5000, 7000 rpms???? Because if any of these points our outside of the efficiency rating that makes the compressor not efficient at that boost for that engine at that rpm. Guess what? At 3000 rpms, the plotted point of lbs/in and pressure ratio is well to the left of the surge limit.

So guess what? You bug me.

Either way, back on topic. To run 6 - 8 lbs, all you need is a t3 50 trim from garrett (or any comprable sized turbo from another manufacturer.) But I wouldn't go much any smaller than that. If you want more like 10 - 12 lbs, I would jump up to the 60 trim. Good luck.

great info guys..

I stipulated for flow levels in my post. Re-read it an comprehend it this time LOL.

yah knowing the air flow requirements for the motor will be better to decide on which turbo to go with. when u know that u can plot both points on each axis (ie 2.3 pressure ratio for 20psi, and say 24lb/min for the air flow axis)

this site may help some:

Exactly! The point is many T3 compressors can efficiently provide 20 psi. However you still have to pick one for your lbs/min of airflow.

Hey monkey ***... just a quick check... if your running, hmmm, 3.0 PR... what would that amount to? hmmm, 28+14.7 / 14.7 = 2.9 PR, soooo if i'm reading the map correctly, you can boost 28lbs on a 45 TRIM T3 AND STILL be in the 70% efficiency range. My statement was by NO means inaccurate.



By moving up to the 60 trim, you can easily see a 2.8pr is supported within the 70% efficiency range. This is about 25psi, but the big difference here is airflow. Notice how the 60-trim flows almost 10lbs of air more per minute at the same boost level. That's the difference.
