someone please try to help me out so i can go back and make more power

I see two possible culprits right there, but thats not the whole story, by looking at your graph, it looks like its in the tune. Post up some arf's, and fuel and timing maps.

What system is the car being tuned with?

Are you sure vtec is engaging properly?

Is the timing on the motor synced? I would check cam/engine timing.

jdmb16turbo

hey all i got was the dyno graph from him or i would post it

jdmb16turbo

its tuned on crome gold.im sure the vtec is engaging right.it they check timing it was right.i didnt have a tube tube on it he said it was sucking in the hot air.but i dont think that would make that big of a difference

Turbo manifold

that graph is pretty choppy after vtec, and doesnt crome gold still have some bugs?

its gotta be the tune, before vtec looks like sex then once it kicks in, somethings happening either the tune, or maybe somethings mechanical.

The graph looks odd, and a Log manifold and big cams will kill it too, ditch the cams and get a decent manifold, a Dart Block and a Log Manifold shouldnt even be used in the same sentence. Not having a dump tube will kill the power too if the turbo is sucking it back up.

jdmb16turbo

^^^what do you mean by the graph looks odd?what kind of mani should i go with and also will it mess up my tune if i put gsr cams back in it

jdm602

the graph looks odd up top, after vtec...it shouldnt be that choppy. whats your duty cycle at for the injectors? your not maxing those 450s out? dont think cams are the problem. it think it might be something mechanical, after vtec kicks in.

jdmb16turbo

what you mean mechanical like what should i check for?im needing to fix this so i can make more power

dude your motor doesnt have to be built to make over 500 im all stock and got 740whp in my hatch stock single cam

LMAO Nice first post.

He forgot too mention compression test shows 120s and 130s, thats kinda low!!

96 GSR-T

lol, had to re-quote this for emphasis

96 GSR-T

Its choppy after the crossover, and obviously you have super low power. Yes GSR cams will change the tune, but if everything else is in line they should make more power with your junk manifold that whatever those cams you got in there now will.

120-130comp is very low IMO, I use the same dished Wiseco's and at 8.8:1 I read 190 on my compression test, did you do a leakdown test too?

jdmb16turbo

^^^yeah my buddy redone the comprssion its between 135-140 in each cylinder.he also has a built h22 with the same compression in each cyinder he made 238 on 12 psi

jdmb16turbo

the thing is what do i need to do to get my power

jdm602

more boost, bigger injectors, retuned. im assuming pump gas? if so maybe look into a different gas. then you can make a lot more power.

jdmb16turbo

i was gonna use the 1000 cc injectors but they didnt have no seals for the bottom of the injector.didnt have the boost controller hooked up or i would of pushed more.and it was just plan oh 93 pump gas. whats the most you think i can get out of my setup without changing the mani and turbo right now

jdm602

well if nothing is wrong with the motor, i would put the 1000's in and tune it on ethanol if you can get your hands on it, that or q16. oh and up the boooost too.

motor could prolly handle 500-600 wheel. with that low of compression you gonna lost of boost tho. idk if the turbo you have is that good of a choice but you can see what itll push.

jdmb16turbo

motor should be fine.if something was wrong with the motor wouldnt it at least be smokin if something was wrong

blinx9900

Lots of bad info here, people claiming pump gas and low compression to be the problem please stop posting. The Drag mani is holding him back and its unclear what turbo is being used.

The low compression pistons are NOT the problem at all, i have 8.3:1 and make 340whp at 12psi with my 3076r on a 1.6 b16 with 91 octane!!!

jdm602

no maybe no smoking at all, i saw a thread where some guy bought a head from someone that didnt think the pins in two of the mid rocker arms was necessary, and his dyno just dropped off after vtec. that or maybe its something with the lma's?

jdmb16turbo

lma's whats that?
