Re: Help- Built engine makes less power than before (dyno graph)
I have Head studds in and only 4k miles on the new engine so the HG should be just fine. the engine was built to handle boost.
I guess i am going to put the old F/I back in and see what we can do with that. there has to be another issue here though. I just cant put my fnger on it quit yet.

Re: Help- Built engine makes less power than before (dyno graph)
oh one other thing. it was 105 degrees acourding to the electric thermostat by the computer. dont know how acurate that was but it was AT LEAST 98 degrees out side
Re: Help- Built engine makes less power than before (dyno graph)
Doesn't emanage ultimate have O2 skewing? If so no reason you won't be able to run srt4 injectors on less boost and this would leave you plenty of fuel at WOT and you wont' be maxxing out the injectors. Just a thought.. either way good luck and don't destroy that new built engine.
Re: Help- Built engine makes less power than before (dyno graph)
150? How can you possibly come up with that number? The regulator alone is at least 130....
The stock fuel pump is worthless. I wouldn't try running it at more than 5 or 6 psi, if that. If you do what I suggested, you will make the power you're looking for. You have way too many weak links in the setup right now to make decent power. You need to get the right parts to do what you're trying, there are way too many things to troubleshoot with the setup the way it is now.

Handling power and handling detonation are completely different things. You can destroy forged pistons and rods with enough detonation, I've seen it. Don't think that just because you have that done your engine will survive anything. Headstuds won't prevent the head from lifting with detonation...
Re: Help- Built engine makes less power than before (dyno graph)
As far as getting the right parts, besides the fuel system, i have the right parts. I will try and get a print out of the A/F and what it was doing and give you more info on it.
And i know you can destroy parts. it doesnt matter how new they are I know it happens to the best of them. What I am saying is that if you take out some compression you can replace it with a little more boost. it it wasnt for the turbo the car would make less than a stock civic @ 9:1 compression. Now I know i am no expert at this by any means and that why i ask for help. I will try to update the first post and be a little more specific once i get more info.
Re: Help- Built engine makes less power than before (dyno graph)
May I ask what your goals are this may clear up some questions? Are you shooting for 200whp safely or 300whp. Do you plan on running 15psi daily or was that just to see how much power you can make at that boost level?
Re: Help- Built engine makes less power than before (dyno graph)
I want a Daily use of 230-250. so i am literrally 100hp off my goal at this point. I just bought a second car about 1 hour ago so i can park this one after i pick it up this weekend (I am not rich, the damn car was only $545 tax and title!)
I have already set up to meet with my tuner on friday when i get off work and we are going to go over the parts and the build peice by peice until i am confident that it is the fuel and not something else. the actual power of the car was more like 175 HP. he told me before the car ever touched the dyno that his was a proven 10% lower than others and that it was long over due for a calobration. not to mention the 100+ degree weather here in Sout GA.
If i can make more power with less boost, then by all means i want to. But i feel as if i can run 13+PSI and pull it off.
Re: Help- Built engine makes less power than before (dyno graph)
Dial it back for now. I agree with andy you're short on gas, and I think its pretty dangerous to be running piggyback trying to run 10+ psi. All engine managements have their place... you wanna get up into higher boost levels, you need to step up the game.
Get it running 7psi for now just so you're sure it works, and upgrade the fuel and management, then try again. I'd also look for a leak in the system with the boost dropping off.

yeah i am currently in the process of replaceing all of the worm clamps with "T" clamps. much more durable and you can tighten them with out the worry of braking them. i went throught the system last night and found a small leak where the nitrous was hooked up and fixed it. It wasnt very much of a leak but the turbos respons picked up a good bit this morning when i drove it.
I will back off the boost to about 12PSI, down from 15. but I wont be driving the car as much now thankfully.
Agian guys, thanks for all of your help and to anyone who posted in this thread. I learn something new every day it seems.
Re: Help- Built engine makes less power than before (dyno graph)
where is the cam gear set at?? where is the AFR curve on the dyno? is your tuner retarded? im surprised he even tried after seeing how lean it would run.

Re: Help- Built engine makes less power than before (dyno graph)
FYI I made 280.1 HP before I maxed the stock fuel pump out. This was at 17.5 PSI. The only mod I did to my fuel system was DeatschWerks 750cc injectors, kpro and I modded the stock in tank FPR with a boost ref line so it would increase pressure at a 1:1 ratio. I refused to do a return conversion because im in cali and it SUX out here with emissions testing… and cops actually know what to look for.
