Circuit Star-29

Was at the dyno yesterday while Crescent from C-speed was doing some tuning... He made 216hp and 159 torque on a DynoJet 7. Car baselined at 124 and 105.

Stock b16 w/ GSR cams
Tuned w/ Crome
2.5 inch exhaust (custom)
Greddy T3/to4e
TE Manual Boost controller...

The owner got a little upset because he stated a friend of his was making 300 on 10 lbs... Just curious about power production...

A/f was dead on at 12.5, timing was very conservitive... The owner did mention to me that his clutch had slipped during the last dyno tune a few months back...I explained to him that that was probably an issue...could have been losing a lot of power due to clutch slippage...

That is pretty low. I would expect at least 240 whp, and even at that its pretty weak for 9 lbs.

Circuit Star-29

Yes, I would think the clutch takes alot of the power away from the motor...

tallyturbo

that is really low imo. i guess its because of the size of the turbo. 9 lbs on a smaller turbo isnt the same as 9 lbs on a bigger turbo. im not positive but i think i am over the 300hp mark with my setup at 10 lbs

jdm b16a
garrett t3/to4e 60 trim

my b16 numbers are in the sig

i feel the same way but need more info on the car. greddy mani? or 18g? i know you said t3/t04e.

i laid down on the 18g 272/242 on 11psi with a spike up to 15-16. not much help i know but it is kind low?


maybe he has some boost leaks like i had. my 1st dyno was 224/176 but the damn last bolt on the greddy mani was not tight so there was 1 boost leak. I know i fixed a few more.


Best of luck tho.

That pretty low my stock b16a @7psi run 240fwhp. 165fwtq alil slipage @7krpm-8k

I think is ur clutch bro

Edit;
But my question is why his tq looks kinda ok maybe not the clutch or maybe bad compression

Compression test

civicdx1

my stock b16 put down 225hp at 7 psi with a drag t3t4e kit.i also had a boost leak at my manifold.

kdawgy2k1

Hey guys wassup... My b16a tuned really conservative and low timing made 215 hp and 165 tq to the wheels on 6-6.5 psi... Car isnt to stock though its got 9.0 compression pistons with stock b16 cams..

Circuit Star-29

Hey, guys...

Thanks for all of your replies...I find it really interesting the numbers you guys are getting and why this motor isn't seeing at least similar numbers...One should assume that boost is boost no matter the turbine...I feel that the differences in turbines show during spool and would make a "different" type of boost.

Can you guys list the dynos you performed your tuning on?

I see similarities here....Interesting...

Im running 9 psi on a 50 trim t3/to4e--.48 a/r turbine housing , 2.5" DP and 60mm Spoon exhaust.I got 210whp/151tq--like the guy above me my B16 is 9:1 though.Also remember the more exhaust restriction, the less power it will make (explains my numbers anyhow)..I notice you said "dead on" at 12.5:1 a/f---that seems way lean to me, my car runs 11.3.-11.7 thoughout my whole boost section, I mean damn the shop that tunes mine runs built NA cars at 12.5:1

atec

we made 300hp/270whp at 7psi on our last customers car,
stock b16, w/ stock cams, internals etc.
it was with a full-race stg1 kit (t3-t04e)

..so I think 216hp was a little low.
Better replace the clutch

tallyturbo

i think iti s also your clutch, but like i said your not going to make big numbers on low boost with a small turbo.

That is not the case. As said before 10lbs on a small turbo is not the same as 10lbs on a large turbo. I made 240whp with a 57 trim t3/t4 at 10lbs and 260whp at 8lbs with a SC61, both on a stock B16.

asilaydying1984

300 on a b16 at 10 pounds is very very unlikely i think he should be happy to get anywhere near the 250 mark at 10 pounds

spoon95eg

I don't believe 10 psi will get u to 300 mark on a stock b16 pump gas. But u will on a race gas, cams and IM for sure .

Sooo in my opinion @10psi pump gas stock b16---- 300whp Bull cRap

Well you know what they say about opinions....

I think this person is looking for facts not some uneducated opinion like your own. 300whp at 10psi has been done by many people, stock motor, stock cams, and pump gas. That is a fact.

92TypeR

Crescent, any more details on the size of the turbo? Here is a graph of a stock B16 we tuned a few months back.

atec

300whp on pumpgas is not a problem on 10psi..

Do you live in the 80`s still?

spoon95eg

whats the date today?????

slowhonduh93

I made 256whp and 178wtq @ 9psi... stock b16, skunk2 IM 450cc injectors, apexi ws catback with stock cat... yeah yeah I know... turbonectics t3/t4 57 trim .63 ar....tuned on uberdata

atec

By the REAL date its 06, by you date Im not shure

Try research some before throwing BS comments about things

spoon95eg

Will do N00B lmfao

Circuit Star-29

Thanks again for all of your replies...

Just to clearify, this was a customers car...

I'm no tuner but I've seen better results on NA motors, such as mine, with at around 13.5... I have seen some motors run pig-rich and make more power...such as an RSX-S we did a few months ago...thing made 14 more WHP at 7500rpm at 10:1 A/f then it did running it any leaner...

I think a big problem here is the clutch...Although I am seeing numbers close to those I posted.

I think the clutch should be replaced...

This is interesting...shows you the extent of the knowledge I have about boost... I've been reading alot of posts on a number of setups and I'm starting to see this trend you speak of.

This is Nathan... The only specs I "THINK" I heard from the owner were T3/To4E w/ .62 AR.

FYI guys, leaner mixtures will normally result in more power, but raise the risk of engine failure due to lack of thermal management. Yes, most turbo cars will easily make more power at 12.8:1 than they will at 11.8:1, but the motor probably won't last as long..

Personally, I run them on the rich side, I'm not out to set power records, I'd rather keep the motor alive..
