Spun the 4dr EF on the dyno, results inside.
 

Had a chance to take my turbo LS-vtec 4dr out to the dyno on saturday and got some baseline numbers.

Motor is a LS-vtec with 90 B18a bottom end with mahle 9.1:1 forged pistons, scat rods, etc... head is a 99 B16a2 head, left it stock for now, i have a ferrea valvetrain and crane cams new turbo vtec cams lined up, just need some cash
management consisits of a PM6 running turbo edit and AEM FPR set to 37psi.

dyno run was done on a dyno dynamics with no correction factor, unlike the dynojets out there.

first pull: 120.7whp with major lean out in the top end, vtec activation at 4900 rpm.
second pull: 140.9whp, upped the fuel pressure to 52psi, moved vtec up the 5200rpm
third pull: 135.6whp, upped fuel pressure to 60psi, left vtec at 5200rpm, definate loss in power.

boost was at 3psi, with 440dsm injectors.

the tuning was primarily just a basemap i created with xenocron's basemapper program. We went back and played with the values for about an hour, but i didnt have time to get it back on the dyno. I will be going back this weekend now that i have 1000km on the motor, i will put the 10psi spring back in and give her ----.

Overall goal is 15psi, but my 440's max out at 11psi, so itll be on to 600cc injectors and a new fuel pump before it gets the 1bar spring.

ill post up the dyno sheet when i grab my willem burner and spares chips from the dyno shop.

Re: Spun the 4dr EF on the dyno, results inside.
 

i dont know too much but i would think the ls/vtec would have more then that na much less running 3psi, someone else can confirm, just my 2 cents of course

Re: Spun the 4dr EF on the dyno, results inside.
 

my stock N/A LS made numbers like those :-X

Re: Spun the 4dr EF on the dyno, results inside.
 

I thought the same thing. Good luck with the setup though. Keep us updated.

Just out of curiousity how much do you have in just the LS/VTEC setup less the turbo stuff?

Re: Spun the 4dr EF on the dyno, results inside.
 

my stock b16a puts out better numbers, basemap or not, those seem pretty low for an lsvtec.

Re: Spun the 4dr EF on the dyno, results inside.
 

Why are you running such high Fuel Pressure. At what point are you hitting 60psi? I hope not at idle!

Re: Spun the 4dr EF on the dyno, results inside.
 

Wow that seems super low. How long has this engine been built and running for or are you still breaking it in? That just seem really low for a stock LSVTEC. ???

Re: Spun the 4dr EF on the dyno, results inside.
 

Does this account for the low dyno numbers??

Re: Spun the 4dr EF on the dyno, results inside.
 

dude, those numbers are hideous! 440's max out just a hair over 300whp, so you have a lot of work to do before you even think about maxing those injectors out. i'd be worried about a lot more things other than getting new injectors :P what kind of goal is '15 psi' ??? you just want to be able to say "hey, i'm running 15 psi!" or would your rather say "hey, i put down 400whp" ?. what turbo was this with?

Re: Spun the 4dr EF on the dyno, results inside.
 

believe me, im not too happyy with the results. Im diagnosing the problems as i can find them.

projecteg: its about making power and being able to say i pushing 15psi. 15psi is useless if im not putting the power to the ground the way i want it.
turbo im using is a T3 48 trim turbine, 60trim compressor

im into the complete setup foir about 1500us, if that. It helps to work at a speed shop.

Ill keep everyone updated.


I found an exhaust leak at the manifold flange, gonna fix that and see how see runs.

Re: Spun the 4dr EF on the dyno, results inside.
 

u either have to much fuel or really low compression on a few of ur cylinders

Re: Spun the 4dr EF on the dyno, results inside.
 

with that amount of boost, you're probably just making up for that huge restriction you added with the turbocharger. although, i'm guessing tunning is a big issue here.

dont bother trying to tune with that FPR you have; just set it and do you're tunning with turboedit, thats what it's there for.

what have you done with your ignition timing?

Re: Spun the 4dr EF on the dyno, results inside.
 

my n/a gsr with i/h/e and a afc did 165 whp

Re: Spun the 4dr EF on the dyno, results inside.
 

messed around with it some more on the dyno today.

set the vtec to activate at 5500rpm

FP is set at 52 psi and we are leaving that alone.

we tuned the turboedit some more and pulled a 160hp out of it. goes way rich at past 6000rpm 10.0:1 a/f

so ill pull a little bit of fuel from the top end and go from there.

tuning takes up a lot of the time and effort thats for sure.

if anyone has more tips, keep them coming, its all definately helpful.

the exhaust leak was coming from the manifold gasket. Ordered up a OEM honda and gonna turf the mr.gasket copper piece of ---- in the trash.

Re: Spun the 4dr EF on the dyno, results inside.
 

get that leaned out a bit more and you ought to have a bit more luck, get yourself in clean 11.5-12:1 AFR range and a decent but conservative timing map, then up the boost.

Re: Spun the 4dr EF on the dyno, results inside.
 

i know its unpopular therory, but we mainly use dyno dynamic dynos here is australia. Our readings are way lower then u guys inthe US. a stock b16a will pull 104hp and a header/intake might pull 120whp. if its anything like ours, those numbers seem pretty much spot on. for 3psi and 9.1 compression. Im guessing the gains u saw on ur 160whp run were through extra boost with a fixed gasket?

You suck at life, and at making HP.

Re: Spun the 4dr EF on the dyno, results inside.
 

52psi static fuel pressure is still pretty high. there's no need to raise your fuel pressure unless you're running out of injector, which i think you're far from doing. i would set the fuel pressure around 45psi.

Re: Spun the 4dr EF on the dyno, results inside.
 

No seriously do everyone a favor and remove yourself from the gene pool.

Re: Spun the 4dr EF on the dyno, results inside.
 

will do man, ill give it a shot and see what happens.

Re: Spun the 4dr EF on the dyno, results inside.
 

do me a favor and ---- off from my thread unless you got something 1/2 assed to say

Re: Spun the 4dr EF on the dyno, results inside.
 

i agree

Re: Spun the 4dr EF on the dyno, results inside.
 

I'm being concise with bashings because there are a million other ricers out there just like you with more money than sense.

You've obviously thrown some serious coin at the car. It takes at least a couple grand to do a bottom end build on a VS/VTEC and get her running. We'll say $2,500 to be fair.

Then you even say that you've put another $1,500 into the turbo setup for a little 48/60 T3.

Not too bad honestly, $4,000 in performance upgrades to be very conservative and just consider the motor and turbo. Now your saying your best pull is 160whp. ::)


I could keep going on about you being a retard for spending four grand and making #'s like that, but instead I'll offer a few tips:


- 440cc injectors will do anything you can throw at em with a small T3 turbo. Supporting modifications are your friend (walbro 255 fuel pump, wideband to tune on the street since dyno tuning is useless, tuning, tuning, and more tuning)

- Stop ------- around at 3psi, you have the tuning software and the fuel to at least do 9-10 pounds no problem. Of course it is going to be pig rich at retarded low boost with big fuel injectors and high fuel pressure.

He's breaking in the engine(in some sort of way) so he wasn't just doing 3psi for shits-n-giggles.

"breaking in" motors takes about an hour tops.

Re: Spun the 4dr EF on the dyno, results inside.
 

more money then sense? good one there jackass.

If that was the case, i wouldnt have spent on a EF chassis or a LS motor to begin with.
The motor is peanuts when i work at a speed shop and i assemble the motors myself. There is absolutely nothing wrong in being easy on a motor for the little while, if you feel otherwise, thats fine, but id rather not beat the ---- out of a motor on start up.

As well, i didnt ask for your bullshit, i posted up results and hoped to gather a consesnus as to why the power was lower than normal and what i may be doing wrong and go abouts correcting it.

If i wanted useless comments i would have gone to hondatech and posted my ---- there.

for someone that comes off as helpful in other threads, you seem to love to beat down on my thread.

"Although these pistons came out of engines which were raced for a full season, they weren't set-up with any special clearances or other preparation.

These engines were never worked on prior to being raced. They were totally stock as built by Honda.

The only difference was the break in method they used...

The one on the right was broken in as per MotoMan's instructions.

The one on the left was broken in exactly according to the owner's manual. The resulting leaky rings have allowed pressure to "blow by" down into the crankcase on acceleration, and oil to "suck-up" into the combustion chamber on deceleration.
Needless to say, this bike was slow !!"

Re: Spun the 4dr EF on the dyno, results inside.
 

if you map out your turbo to your motor and motors' operating range you'll find the region where that turbo will work, if you are below the efficiency range then any gains are lost, don't waste your time running 'too low' boost. You'd be better off just to remove the cold side altogether and block it off with a plate, and you'd probably get higher numbers.

Make sure you are in the efficiency range and you'll see a big difference.

Re: Spun the 4dr EF on the dyno, results inside.
 

these are my suggestions..
go obd1..

turbo edit is great tuning software.. but you're limited in obd0

get a Moates Ostrich rom emulator and do some real time tuning

before you put ur car on the dyno.. get the a/f tuned on the street...
then you can take some time and work on your IGN tables on the dyno and not have to screw around with getting your a/f set..

my old all motor lsvtec made 160 whp baseline.. at that time i didnt have the wbo2, or my rom emulator.. i took 3 chips with me with slightly different tunes.. that was about 2 years ago.

anyway.. datalogging + wbo2 + rom emulator = how to make more power :)

about breaking in motors.. everyone has their own way of doing it..
i've got a buddy who ran his car nice for 10 miles then couldnt stand it any longer and ran the piss outta it.. he's run that race motor for 3 seasons and the motor is still running great.. my machinist who builds $35k race motors for nascar style race cars has an engine dyno and he's done testing on breaking in the motor.. says after 8 runs on the engine dyno the motor is 98% broken in.. but if someone wants to break their motors in the long way.. its their decision.. i went 250 miles on my lsvtec before running the piss outta it.. had 230 psi across the 4 cylinders when i pulled the motor and traded it for a stock gsr motor. good lsvtec.. had other plans tho ;)
