Motor, mods?

Pics?

 

[mike@synapse]

well the filter alone is probly robbing a lot of power. then the fact that the turbo is probly sucking in all the exhaust gases from the wastegate would also cause a loss of power.

 

[bizoneoeh]

^ "robbing alot of power" the filter may be loosing him a little power but not alot like you say. I'm not sure if he did but alot of people take out off their filters at the dyno.


Not bad tho you have 8hp more than I did but all I have is a single cam @ 8psi

 

[civic92si]

i didnt actually i left it on. that one thing i forgot to do. but i think imma get it retune again. maybe it run to rich and it drop..or boost lag b/c its to rich

 

[TomTomTuning]

What size T3T04?

Honestly 194 @ 6lbs seems pretty low...
The car should put down about 150-160 N/A, then 6lbs should put that at 210-220 ish...

What are you suing for engine management, and is it tuned?

 

[civic92si]

yeah t3/t4 .50AR for both side. using chrome. tune by rd-tech. also if i leave the wastegate exhaust i can lose power?

 

[Billy.]

you need a dump tube for the wastegate (so do i though ). the numbers do seem kinda low, my lsvtec made over 280whp on 7psi same size turbo. what size is your downpipe/exhaust? the log mani would make a difference too

 

[civic92si]

i believe its 2.5inches for down pipe. so different manifold makes a different? also this is why cheap turbo are not as good as good turbo. i think imma switch to a td05HR from evo3? or should i get another .50 AR? EDIT!!! I FLOOR on 3rd stop at 8k it was 5psi!!!! s**t my i must have a boost leak!! meaning at the dyno its 5psi!!!

 

[mike@synapse]

5psi 6psi whatever it is something is wrong. im not sure all the parts you are using(t3/t4 doesnt mean much without trim or size) but a turbo gsr should be putting out a bit more than that even with a very basic setup with a conservative tune.

 

[lkailburn]

agreed. i've street tuned 2 gsr's with similar basic setups and they were each putting down around 250whp

[civic92si]

but how much were they boosting?

 

[Winki]

7-8ish psi i made 276whp
my buddys stock b16 on 8 psi made around 257whp

seems just a wee bit low and boost leaks

 

[12.8:1 Ls/vtec]

The way the graph is it appears that the tuner does not know how to make a good tune seeing as how the vtec engagement loses a lot of power. Mine actually gains a whole lot of torque and hp with no dips where vtec engages and is much more slick.

 

[civic92si]

so can that cause the problem of losing HP? also i guess i will retune it when i have the other motor in. in that way i wont lose so much $$ =D

 

[DarkCreep]

Why does it dip?

 

[civic92si]

tuner said that it might run to rich when vtec kick in. that why it dip. others said my vtec engage to early.

 

[bizoneoeh]

vtec isn't s**t when you are boosted.......





but then again, vtec isn't s**t anyway.

 

[Winki]

but then again, vtec isn't s**t anyway.

lol mine means something to me its like Vtec times 10

tuner said that it might run to rich when vtec kick in. that why it dip. others said my vtec engage to early.

why did your tuner not adjust AF then?

 

[civic92si]

well before my car was bogging. when vtec ingaged, it runs lean then jump to rich. so he rich it up a bit.
