Thanks to Tim at Xact Dyno in Tempe, AZ. Before the T-day trip I dropped the car off to get a new AEM Series II standalone plug and play computer. Yaayaa I sold out on the stock computer and FMU setup. I finally had enough with dealing with RaceGas and had a few $ in my pocket for once in my life soooo..
In went the new unit out with the old and FMU in favor of a new fuel pressure reg and on the dyno she went. Tim calls and says all is good you will like the results. Some of you may remember my New year's trip experience from last year. Not good. Looked kinda like this after OSoto provided the 10# spring I asked for to replace my 7# one.

Hope we don't have that happen again.
Well now new computer allows some controll so I decided to try the bigboy spring again. Looks a bit safer now but will definetly be testing the stock rods. (verified visually that they are different than the last engine that let go..supposedly forged variety in this engine)

Results = (RED)12.5# boost on pump gas as opposed to (GREEN)7# on 110 Race gas before. I can really feel the torque now when on the skinny pedal. Not to bad for a little minivan motor. Gets me around the dunes pretty good.
I'm happy for now until I get some full forged Pauter rods and new pistons so we can do maby say 15-18# boost??

Wow..... Im Impressed!!! I Need to go for another ride down the drags in your car.

So almost 23 more hp with pump gas? and an upgrade and from 8 to 12lbs of boost ...... pump gas?..... 435 hp. What?

Happy to see you will be the first to try out the Aem.

I can tell from running 8 now from 11 on my car. Turned it down she was going to blow for sure. I want my 11lbs back.

How much to switch it over Chad? Did he get you the computer and hook it all up?

Im next.. I wana play!!

Yup Tim handled it!! He is a dealer for AEM and tunes like a madman. Tim@xactdyno.com. Computer is $1200 + dyno time and ?? depending on what else has to be done. I did all the de-install and re-install myself before taking it to him with exception of the computer which is only 3 plugs. All in all maybe $1700. Worth it? I'm happy and now have one of the major obstacles out of the way so I can do a "built Honda" as $$ permits.

Nice power curve.

What transaxle you running?

Thats fantastic!!!!

Man... You really had a flat spot/loss of power at 3500-4k before the ecu...
I bet she is snappier...
Awesome power curve my man!!

I can tell you that I can see a difference the way his car handles the power now. I think he went to a much lighter front tire setup now

Oh yah she is way more responsive now. Running a 2D with all the good stuff in it. I hope it holds togather.

Lifts the front in 3rd gear now with a heavy foot.

Bring it.....

Looked for ya for quite awhile Saturday at the drags......

I was there Friday and rode to glamis on saturday...didnt make it back in time for the drags....do you have car to car communication?..

Did you have to up the injectors?

Did the tuner lock the comp?

The stock injectors are about at top of their range.. I may go to some 550cc injectors down the road. Computer is fully unlocked and programmable by anyone. free updates too

I used the same ems tuned on e85. Works great!!! @ 16lbs of boost it made around 550hp and 587tq (if my memory serves me right) with alot of timing pulled out on the top end. The motor lived on the dyno for a few pulls. took it to glamis, one pass, and TWO rods let go. Guess the rods couldnt handle it....lol. Ive talked to someone else that has a turbo honda motor running 16lbs of boost with rods, the rods held up fine but split a sleeve. I know darton makes sleeves for this motor, I believe with a 89mm - 90mm bore.

If youre goin to go over 12lbs of boost the rods should be replaced cuz they are the next weakest part of the motor

Rods pistons and sleeves are all on the wish list along with a stout spring. I will see what the future holds.

Very col. Keep us updated after each trip

Fixed it for ya bro...


I've got all the parts for a 18+ psi monster, but I need a 10k-12k trans...

I have a set of brand new never used RC 440cc injectors for the Honda V6. PM if interested. I am running the same injectors on my J35A3 turns out I inadvertently bought two sets in haste last summer.

Glad to hear that more people are finally realizing what a properly tuned engine can do. Years ago I was on here trying to inform people to go with standalone computers and there benefits and I was made fun of because there were so many people on here that were using stock computers to run their cars claiming it was the best. Here is yet another car that has proven that you can make more HP on pump gas with a TUNED STANDALONE ECU VS. a stock Ecu running on race gas

here is the thread where I decribed in depth what the benefits of a Stand alone ECU was. This is was done with a AEM ECU
honda Standalone ecu Benifits

Hoternhell Did you replace your stock fuel injectors with High flows because looking at your Air/fuel ratio it is going lean in the top end it goes from 11:1 afr directly up to 12.5 AFR at red line. Typically when engines do this it is a sign of running out of Fuel Injector. Afr should be a flat line of 12:1 afr yours is all over the place

Talked to Tim Today.. I take out my Fmu and install a fuel pressure regulator.. Drop it off and its 1500.00 all tuned and ready to go.

Dyno mike... Sorry you got so slammed before.. you said 370 on pump gas and some called BS.. Guess they will have to eat Crow now.

Also Chad is still running meth from what Tim said.. Also said an Intercooler is the way to go.Hmm Kinda took the wind out of the sails of a few..Whole new concept for those that said an Intercooler is a waste of money also...

Serve up the crow, but I still don't believe 370 TO THE WHEELS.. On pump gas??!!
Why, with my upgraded TB,550cc injectors, dual BB turbo, h20/meth all being controlled by an Autronic, I can only squeak out 300 to the wheels on RACE GAS?
I'll tell ya why.. Because all dyno's are different...
If Dynomike is secure in his published ratings, maybe he should take Outfronts bet... No stock honda will hit 400whp on his dyno...

mine was close.. it was in the 380's if I remember right..

the issue in the past with the aftermarket ECU was the cost of it all.. AEM finally come up with a set up that is affordable.. I would have loved to have it tuned, making the power it does now, with the new ECU on pump gas. It just wasn't worth it.

Well.. I'll continue to claim 300hp and keep whooping up on stock ecu'd Honda's...

If ya do the math, with VE, boost, etcc.. you can quickly see these dyno's are inflated unless your motor is 200% efficient...

Tim was also claiming 400 hp today...Could be inflated.

I told him Just give my my 8lbs of Boost no meth and no cooler.. I just want out of the race gas.. He said no problem 1500 bucks.. So do the math and it just paid for itself after a season of race gas for me.

oh I agree... they are a tuning tool... the tuner can make them say anything they want.

I'm re-tuning mine for pump gas too.. Race gas can suck it!!!
I may just take it to Dynomike and see where his magic takes me, I hear he's pretty good with my ECU.

Ive got enough in the shop for one more trip.. Then it might be headed down there.

I think everyone was into the idea of true tuning but the claim that all those stock setups only being capable of 170hp is what started the fun. Close to 3g is what I remember being thrown around at the time for your tune, this seems to less expensive with solid results.

its still close to 3k for the ems, injectors, labor to install injectors (if you dont do it yourself), and dyno time.

My old car layed down 367 WHP @ 5# and 406 WHP @9# stock injectors and stock comp. It was on a Dynojet.

I am wondering what benefits the AEM might have in an na application. I know you can bring down the vtec x over point and that should help drive-ability.

Not to talk down about Tim's abilities, but if he used his water box dyno, it is very generous with the numbers..

yes we know that a car even on a stock PCM will make more than this. This was the baseline that was done on the customers car that he thought ran pretty good. When I asked him what he thought the car was making he said he thought it was around 320whp, boy was he wrong. The stock computer was in a major Limp mode. This was do to the car being setup incorrectly. The thread was never meant to say that a turbo honda on stock computer will only make 170whp it was simply saying that the stock computer can go into a major back up mode with out you knowing.

Now that AEM is making a direct plug and play for this engine the price will go down because I do not have to custom wire the AEM to the car now. Anything that is turbo charged will have to upgrade there injectors or you will not have enough fuel delivery. I do not agree with what Tim@exact dyno is doing, he is asking for problems with running stock fuel injectors and turning base fuel pressure up. On hoternhell's car the fuel injectors are being run at 100% duty cycle which can lead to fuel injector failure resulting in an engine potentially going lean and detonating

Legit duner
you should bring the car down and see what it makes on my dyno. I have been on every kind of dyno through out the country and my dyno has always seemed to read right in the middle. So you either were on a dyno that is ridiculously low or your car is slow

All dynos are different, I will not mention whos dynos on the board here but I have had a 50hp differiental between two commonly used dynos.
My new Honda we are building twin BB turbo, larger injectors, rods, pistons, closed deck, valves, porting etc. all the goodies, made over 325 at 6lbs instantly to the ground (low boost) 16lbs #2 boost, and now 20lbs of boost. I will run it at 18lbs most likely, and yes this is on pump fuel with an aftermarket computer and a large intercooler. I will have final numbers shortly. I need a set of projects or mudders for the dyno my current all terrains keps breaking loose above 14lbs of boost. I will post the final numbers soon, we are guestimating on a conservative dyno 450 plus to the ground. The twin turbos are awesome you can hear them spool at idle and they take off extremely fast at low rpms. Vicious throttle response is what I was going for.



Brandon

Sounds like you nailed it...
Can't wait to hear your final numbers..
You use different camshaft's? Valve springs? TB?
Did you use the single port heads?
What is your primary exhaust tubing diameter?

hells yes!! one of these days ill gather the nuts to take you up on your offer from a few years ago chad...maybe

BRING IT

Running on race gas or E85?

arco 87 gets the job done

I rode in Chads buggy about 4 years ago, I sure did like it.

91 octane for my set up
